Interoperability between versions

Refer to the following guidelines if the system where you are installing SharePlex is in a configuration where one or more other systems will continue to use an older version of SharePlex. An example is when installing or upgrading SharePlex on a target, but the source will continue to use SharePlex 8.6.x.

Versions with full interoperability

The following SharePlex versions are fully interoperable, including the Compare/Repair feature:

  • 8.6.x
  • 9.0.x
  • 9.1.x
  • 9.2.x
  • 9.4.x
  • 10.0.x
  • 10.1.x

To support replication from a higher to a lower version, set the SP_SYS_TARGET_COMPATIBILITY parameter on the source system to the lower SharePlex version. If Capture is running, restart it.

Important: Downgrading from a higher to a lower version of SharePlex is not supported.

Notes:

  • The older version of the SP_SYS_TARGET_COMPATIBILITY parameter, SP_OCT_TARGET_COMPATIBILITY, was deprecated in version 9.0. If your source SharePlex is currently replicating to a lower SharePlex version on the target and you have SP_OCT_TARGET_COMPATIBILITY set to the lower version, SharePlex will continue to use that value after you upgrade to the current version.
  • If you upgrade the target to the current release at a future time, issue a reset for SP_OCT_TARGET_COMPATIBILITY on the source system to remove it from the SharePlex environment. Going forward, SharePlex will use the setting of the new SP_SYS_TARGET_COMPATIBILITY parameter, which defaults to the current version.

    To reset SP_OCT_TARGET_COMPATIBILITY

    1. Stop Capture.

      sp_ctrl> stop capture

    2. In sp_ctrl on the source system, issue the following command:

      sp_ctrl>reset param SP_OCT_TARGET_COMPATIBILITY

    3. Restart Capture.

      sp_ctrl>start capture

Source and Target System Requirements and Data Types

  • In addition to the Supported Operating Systems for Oracle and the Supported Cloud Platforms for Oracle, the Oracle versions listed above are also supported when running on an Oracle Exadata Database Machine.
  • Amazon RDS for Oracle 11gR2 (supported 11gR2 versions are 11.2.0.4.v11 or later), 12cR1 (supported 12cR1 versions are 12.1.0.2.v7 or later), and 19c. Support for Oracle features on Amazon RDS is limited to the default option groups: default:oracle-ee-11-2, default:oracle-ee-12-1, default:oracle-ee-19 & default:oracle-se2-19.

Supported Data Types: Oracle to Oracle

SharePlex supports the following Oracle data types for replication to Oracle targets. See the Conditions of support for additional information.

  • ANYDATA 1
  • B-FILE
  • BINARY DOUBLE 7
  • BINARY FLOAT 7
  • BLOB 2
  • CHAR
  • CLOB 2
  • DATE
  • INTERVAL
  • LONG RAW2
  • LONG 2
  • NCHAR
  • NCLOB 3
  • NUMBER
  • NVARCHAR2 8
  • RAW 8
  • ROWID
  • SDO_GEOMETRY
  • TIMESTAMP
  • TIMESTAMP WITH LOCAL TIME ZONE
  • TIMESTAMP WITH TIME ZONE
  • UDT (User Defined Type)5
  • UROWID
  • VARCHAR
  • VARCHAR2 8
  • VARRAY collectors
  • XMLTYPE 4

Note: SharePlex supports columns that are defined as INVISIBLE.

Conditions of support

1. ANYDATA

  • Replication of ANYDATA is supported, except when it contains a UDT or the storage is defined as SecureFile LOB with compression. SecureFile LOB without compression is supported. Only the following data types within ANYDATA are supported by SharePlex:

    • CHAR
    • DATE
    • NUMBER
    • RAW
    • VARCHAR
    • VARCHAR2
    • TIMESTAMP
  • A data type within an ANYDATA type must be in-row (inside the column data). Oracle encapsulates the ANYDATA type as an in-row secure file LOB. If the encapsulated data is longer than the length allowed for an in-row LOB, that data appears as out-of-row LOB data. SharePlex assumes that the encapsulated data always appears as in-row LOB.
2. LONG and LOB (BLOB, CLOB)
  • Any table that contains a LOB or LONG should have a primary key or unique key defined on it. If a table does not have a key, SharePlex builds its own key from all of the columns except LONGs or LOBs. If a LOB or LONG is the only difference between two rows that otherwise satisfy the Post WHERE clause, SharePlex cannot guarantee that the correct row will be updated.

  • SharePlex supports SecureFiles LOBs as follows:

    • Logging must be enabled.
    • SharePlex supports uncompressed SecureFiles LOBS and SecureFiles LOBS with high or medium compression
    • SecureFiles LOBS are not supported when the storage specification includes encryption and/or deduplication.
  • SharePlex does not support LONG and LONG_RAW data types in a configuration where transformation or conflict resolution are performed.
3. NCLOB

NCLOBs are not supported by Compare/Repair if the source and target have different character sets.

4. XMLTYPE

SharePlex supports the replication of XMLTYPE stored as CLOB and BINARY. SharePlex does not support XMLTYPE stored as OBJECT RELATIONAL. Additionally, the following applies:

  • XMLTYPE stored as BINARY is not supported when the storage is defined as SecureFile LOB with compression. SecureFile LOB without compression is supported.
  • Binary XMLTypes are not supported by Compare/Repair when the source and target character sets are different and require character set conversion.
  • Compare/Repair does not support comparison of XMLTYPE when the source and target have different storage clauses. Compare/Repair only supports compare/repair when source and target are both stored as BINARY or both are stored as CLOB.
5. User-defined types

SharePlex does not support abstract data types and VARRAYs in a configuration where the SharePlex conflict resolution feature is performed.

NOTE: SharePlex replicates tables with the UDT fields in the base type ONLY. In case of columns containing multiple subtypes, replication is applicable only for base type fields.

6. General

If the precision or size of the target data type is not large enough for the data being replicated, the data may be truncated or rounded by the database when applied.

7. BINARY DOUBLE and BINARY FLOAT

The BINARY DOUBLE and the BINARY FLOAT data types are not supported for the copy command.

8. Extended Data Types
  • Extended Data Types are not supported for the copy command.
  • Extended Data Types are not supported on a key column. The keys that do not support the Extended Data Types include:
    • Primary key on the Oracle table
    • Unique key on the Oracle table
  • Horizontal partitioning is not supported by tables containing the Extended Data Type columns.
  • SharePlex does not replicate data with Extended Data Type when target type is JMS Message Queues, File output (XML, JSON, SQL), Event Hubs, or Kafka.

Additional Information about Data Types

Notes about Open Target data type support: 
  • Replication of SecureFile LOBS to non-Oracle databases is supported except if the storage specification includes any level of compression, encryption, and/or deduplication.

  • Replication of LOB operations generated by dbms_lob are not supported when replicating to non-Oracle targets.

  • SharePlex applies replicated Oracle data to the target according to the data type of the target column, rather than mapping to a default data type. Corresponding source and target columns must contain compatible datatypes to ensure successful DML operations.
  • If the precision or size of the target datatype is not large enough for the data being replicated, the target database may truncate or round the data when SharePlex applies it.
SharePlex does not support the replication of data from Oracle to Open Targets for the below Extended Data Types: 
  • VARCHAR2 (4000-32767)
  • NVARCHAR2 (4000-16383)
  • RAW (2000-32767)

Supported Objects and Operations for DML Replication

SharePlex supports DML operations on tables and sequences, with some conditions. DML can be replicated from an Oracle source to an Oracle target or an Open Target target.

Note: Replication to targets with a different character set is supported, with limitations. When posting to Open Target databases, XML files and JMS, SharePlex supports only UNICODE and US7ASCII on the target, but conversion can be performed by an Oracle client installed on the target system. For full details, see the Preinstallation Checklist in the SharePlex Installation and Setup Guide for an Oracle Source.

Tables

SharePlex supports the following DML operations on tables:

  • INSERT, UPDATE, DELETE, COMMIT, ROLLBACK

  • Direct-path loads (SQL*Loader) (INSERT AND FULL ROLLBACK).

    Note: Replication of partial rollbacks of DLOADs is not supported.

The target table must support the column types that are being replicated from the source Oracle table.

SharePlex supports the following table types for DML operations:

Supported table type*

Conditions of Support

Regular Oracle tables

 None

Index-organized tables

SharePlex does not support:

  • Replication to/from index-organized tables that contain LOB or VARRAY columns
  • Replication from a non-index-organized table to an index-organized table
  • SharePlex hash-based horizontal partitioning of index-organized tables

Partitioned tables

None

Views

None

Materialized views

SharePlex does not support replication from a materialized view to a materialized view. SharePlex can replicate the underlying table of a materialized view to a regular target table.

SharePlex does not support the following table types:

  • Replication to/from nested tables
  • Replication to/from clustered tables

*SharePlex does not support the following for any table type:

  • Replication to/from Identity columns.
  • Replication of rows changed by 'UPDATE WITH CASE' syntax.
  • Replication of rows in which data exceeds 319 KB in size, excluding LOB and LONG columns
  • Replication of external tables or tables with external partitions

Sequences

  • Transactional changes to Oracle sequences can be replicated only from Oracle to Oracle.
  • To replicate transactional changes to sequences, the supplemental logging of primary and unique keys must be enabled at the database level, or you must enable supplemental logging for primary keys on the sys.seq$ table.

Secured and Compressed Objects

SharePlex supports DML operations on secured or compressed objects as described in the following table. See "Conditions of support" following this table for additional information.

Secured/Compressed Object Can be replicated to:  
DML on tables encrypted by Oracle Obfuscation Toolkit All target types  

DML on tables with Transparent Data Encryption (TDE)1

 All target types  

DML on Oracle Label Security (OLS)2

 All target types  

DML on compressed objects: Basic, Advanced Row (OLTP) Compression, HCC3

 All target types  

Direct Load (DLOAD) on compressed objects: Basic, Advanced Row (OLTP) Compression, HCC3

 All target types  

Conditions of Support

1. Conditions of support - TDE

SharePlex supports Tablespace Encryption and Column Encryption, both source and target.

The SharePlex  copy/append command does not support TDE.

TDE is not supported for sources on RDS.

SharePlex only supports the AES and DES encryption algorithms.

2. Conditions of support - OLS

By default, SharePlex cannot process rows that are protected by OLS (Oracle Label Security) because users granted DBA privileges (like SharePlex) do not have enough privileges to access those rows. However, if privilege is granted from the OLSSYS user, SharePlex can support OLS. SharePlex was tested under the following OLS configuration:

  • The SharePlex user was granted full privilege to the objects in replication.
  • Test tables with OLS security were created.
  • Data was replicated using INSERT, UPDATE, DELETE, ROLLBACK, and TRUNCATE operations, and ALTER TABLE to add and drop columns.

Note: If the OLS policy data label column is defined as hidden, the data in that column cannot be replicated by SharePlex.

Important: Shareplex does not support OLS policy configuration changes on tables during active replication. Users need to apply these configurations before activating the configuration.

3. Conditions of support - compression

For HCC compression: SharePlex does not support query low compression. Supported types of compression are query high, archive low and archive high.

For Advanced Row (OLTP) Compression: Under certain conditions, Oracle does not provide enough information in the redo log for SharePlex to replicate a DML operation on a OLTP compressed object. Testing of OLTP compressed objects is advised.

Supported Operations and Objects for DDL replication

SharePlex provides default and optional DDL support.

Note: Support for DDL on compressed Oracle objects is limited to the following:

  • SharePlex supports DDL on compressed objects only for Oracle 11gR2 and later source Oracle databases.
  • ALTER TABLE to ADD COLUMN and ALTER TABLE to DROP COLUMN are supported on Basic, Advanced Row (OLTP) Compression, and HCC compressed Oracle objects for replication to all Oracle and Open Targets.

SharePlex does not support:

  • ANALYZE TABLE and ANALYZE INDEX
  • DDL to ALTER TABLE ADD OVERFLOW to an IOT in replication
  • DDL operations issued by the SharePlex database user
  • DDL to ALTER INDEX to an IOT in replication
  • During DDL replication, data containing the ALTER statement related to Oracle extended statistics— 'Virtual by User'— is not supported. Oracle also does not recommend to use the extended stastistics 'Virtual by User'.

Oracle-to-Oracle DDL Support

This section outlines both default and optional DDL support.

DDL on objects listed in the active configuration file

SharePlex supplies default and optional DDL replication for objects whose names are listed in the configuration file explicitly or by wildcard. See "Conditions of support" following this table for additional information.

For details about the controlling parameter, see the SharePlex Reference Guide.

Conditions of support
  1. ALTER TABLE has the following conditions of support:
    • ALTER TABLE DDL that involves multiple tables, such as EXCHANGE PARTITION between tables, requires all tables involved to be in replication.
    • Default DDL support for ALTER TABLE on partitions/subpartitions applies to user-named interval partitions/subpartitions. For system-named (system generated) interval partitions/subpartitions, SharePlex supports only ALTER TABLE to DROP and TRUNCATE the system-named partitions. To enable support for DROP and TRUNCATE of system-named partitions, set the SP_OCT_TRUNC_PARTITION_BY_ID parameter to 1, and ensure that both source and target are updated to SharePlex version 8.6.4 or later. NOTE: This requirement has changed from previous SharePlex releases in that the parameter must now be set regardless of the Oracle version, including for Oracle 12.2 and later.
    • SharePlex does not support TRUNCATE of a system-generated sub-partition if the sub-partition is empty. In such cases, Post stops with error SP-OPO01002. To configure Post to ignore this error, stop Post, set the SP_OPO_CONT_ON_ERR parameter to 1, and add error number SP-OPO01002 to the top of the oramsglist file. See the SharePlex Reference Guide for more information about this parameter.
  2. For CREATE TABLE AS SELECT, SharePlex supports the following datatypes: LONG, DATE, RAW, LONG RAW, ROWID, LONG VARCHAR, CHAR, CLOB, BLOB, CFILE, BFILE, TIMESTAMP, INTERVAL YEAR TO MONTH, INTERVAL DAY TO SECOND and ANYDATA.

  3. For CREATE MATERIALIZED VIEW the following applies:

    • SharePlex supports the following datatypes for CREATE MATERIALIZED VIEW: LONG, DATE, RAW, LONG RAW, ROWID, UROWID, LONG VARCHAR, CHAR, CLOB, BLOB, CFILE, BFILE, TIMESTAMP, INTERVAL YEAR TO MONTH, INTERVAL DAY TO SECOND and ANYDATA. SharePlex does not support ALTER MATERIALIZE VIEW.
    • SharePlex converts a CREATE MATERIALIZED VIEW to a CREATE TABLE, applies the CREATE TABLE to the target, and then replicates the DML that populates the view. SharePlex does not replicate materialized views to materialized views.

  4. To replicate sequences, the supplemental logging of primary and unique keys must be enabled at the database level, or you must enable supplemental logging for primary keys on the sys.seq$ table.

  5. Amazon RDS restricts DBA users from issuing the GRANT command. Because SharePlex runs as the DBA user, SharePlex cannot replicate GRANT to or from an RDS database.

DDL on objects not listed in the active configuration file

SharePlex provides expanded DDL support for Oracle objects that are not listed in the configuration file. SharePlex replicates the DDL statements for these objects, but does not maintain synchronization of the objects through DML replication. Expanded DDL replication is optional and is enabled with the following parameter setting:

SP_OCT_REPLICATE_ALL_DDL=1

Note: Expanded DDL replication supports not only tables and sequences but also a wide range of other objects such as procedures, functions, users, and views, which are not part of replication. Some of these objects may have underlying objects that are in replication. In those cases, Expanded DDL replication applies to the underlying objects in replication, as well as to the object that is not in replication.

Table Notes:

  1. Amazon RDS restricts DBA users from issuing certain commands on an Amazon RDS database instance. Because SharePlex runs as the DBA user, SharePlex cannot replicate the following commands to or from an RDS database:

    • CREATE or DROP DIRECTORY
    • GRANT

Oracle to Open Target DDL support

SharePlex provides limited DDL support for replication from Oracle to Open Target. The involved objects must be listed in the active configuration file explicitly or with a wildcard. There is no optional DDL support for replication from Oracle to Open Target.

The default Oracle to Open Target configuration is represented by the following parameter setting:

SP_OCT_REPLICATE_DDL=3

See "Table Notes" following this table for additional information.

Supported object Supported Operation
Table and IOT Truncate1
Alter table add column2
Alter table drop column

Table Notes:

  1. TRUNCATE TABLE is not supported from Oracle compressed objects to Open Target targets.

  2. The default mappings of Oracle data types to their Open Target counterpart for replicated ALTER TABLE ADD COLUMN DDL is shown in Supported Operating Systems for Oracle . When SharePlex adds the column, it defines it with the default data type. This mapping applies to the entire configuration (not per table).

Non-supported Oracle Features

This is a list of commonly used Oracle features which SharePlex does not replicate and are not listed elsewhere in this document. Since both Oracle and SharePlex continually change and improve, this list of exclusions cannot be considered complete. Unless an item is stated here as being supported, assume that SharePlex does not replicate it.

Object/operation/feature Not supported
Oracle operations Operations that do not appear in the redo logs. This includes any DML or DDL not in the redo logs, and also PL/SQL packages which do not write results to the redo logs, for example, dbms_shared_pool.keep and related packages.

dbms_scheduler.create_job

This object is not supported.

Flashback

SharePlex does not support the Oracle Flashback Table feature. If the SP_REPLICATE_ALL_DDL parameter is enabled (value of 1), SharePlex may try to replicate the flashback DDL, which will return an error. To perform Flashback Table on a table that is in replication, use the following procedures in the SharePlex Administrator Guide to work around this issue:

  1. Remove source objects from replication
  2. Perform the flashback
  3. Add or change objects in an active configuration

Known issues

Known Issues in this Release

The following is a list of issues, including those attributed to third-party products, known to exist at the time of release.

PostgreSQL known issue
Known Issues Issue ID

While running the pg_setup utility, if users encounter the "file not found" problem on a Linux system , even though the file is present. This issue occurs because the SharePlex has upgraded the OpenSSL library and the PostgreSQL ODBC drivers continue to function with the older version of OpenSSL.

Workaround: Create a symbolic links to the OpenSSL libraries of SharePlex in the <prod>/lib directory.

For example: The symbolic link libcrypto.so.1.0.0 will point to libcrypto.so.1.1 and the symbolic link libssl.so.1.0.0 will point to libssl.so.1.1.

Commands:

ln -s libcrypto.so.1.1 libcrypto.so.1.0.0

ln -s libssl.so.1.1 libssl.so.1.0.0

 SPO-22081

 

SQL Server known issues

DDL Drop Column known issue
Known Issues Issue ID

While activating a config file with an Oracle SCN number, users are not able to delete a column in a DDL activity.

 SPO-21993
General known issues
Known Issue Issue ID
The reported core file was not generated on systems running Oracle 11g on the SunOS, and Linux operating systems. 66306
If the customer issues an "ALTER TABLE ... MOVE COMPRESS" DDL command against a table in replication, SharePlex will replicate the DDL to the target by default. After post issues the DDL, if the target table had indexes, they are now unusable and post will subsequently fail trying to apply changes to the table. If post gets an error on the table such as "ORA-01502: index XXX or partition of such index is in unusable state" , the user must rebuild any indexes the table may have before restarting post in order to rectify the situation. N/A
SharePlex copy is not supported for tables created with "MAPPING TABLE" clause. SPO-19626
Windows known issues
Known Issue Issue ID
On Windows systems, the uninstaller does not prompt for the version of SharePlex to be removed from a system. When there are multiple versions of SharePlex installed on a system, it removes only the first installation. N/A
In the Windows environment, always run sp_ctrl from the same drive on which you have installed SharePlex. If you run sp_ctrl from another drive, you will be prompted for a login ID and password. After you provide the login ID and password, sp_ctrl will run normally. N/A
If the user wants to change the installation directory for a given port, the user must first uninstall from the previous location. Note that if the user wants to keep the previous VARDIR it should be copied to the new location prior to the uninstall. 62620
Installing on Windows 2019 as Windows Administrator user will cause sp_wallet and qview to fail. Workaround: Set NUT_TREAT_ADMINS_AS_ROOT environment variable to 1 for the Windows Administratoruser before starting any SharePlex utilities or applications. SPO-20785
During installation when upgrading from 9.2.x it is possible to get a file not found error in the PTC NuTCRACKER Platform Components.
Workaround: Rename or remove the mks_oe directory under the SharePlex installation directory before upgrading.		 SPO-20910
ASM known issues
Known Issue Issue ID
If the redo_log or archive_log that SharePlex is currently reading is involved in “rebalancing” due to the removal of a disc group, the Capture process will pause until the rebalance procedure for that file is complete. N/A
On raw device ASM systems, the sp_desvr may get stuck and the process can not be killed even when kill -9 is issued; users must reboot the system to recover from it. 61713
Startup known issues
Known Issue Issue ID

If you have SharePlex configured to start from a startup script and it returns an error similar to: System call error: sp_cnc (connecting from cdrpx.mcit.med.umich.edu) Bad file number Can't dup2 stderr try adding nohup to your script. The nohup command directs a command (in this case the startup of SharePlex) to continue in the background after the current user (the script) logs out. The syntax is:

cd /product_directory/bin

nohup ./sp_cop &

N/A
Character Sets known issues
Known Issue Issue ID

Avoid replicating NCHAR data types using different character sets such as AL16UTF16 on the source machine and UTF8 on the target due to byte size limitations. Oracle stores NCHAR data with a maximum limit of 2000 bytes. A fixed length NCHAR character set such as AL16UTF16 has a different maximum number of characters than a variable length NCHAR character set such as UTF8. For the fixed length AL16UTF16 character set, each character is stored as 2 bytes; thus, the maximum number of characters is 1000 for NCHAR data. For the variable length UTF8 character set, the maximum number of characters a column can accommodate depends on how many bytes each character requires. If you replicate 1000 3-byte characters from a source machine using the AL16UTF16 character set to a target machine set to UTF8, you will get the following Oracle error message on the target, since it needs 3000 bytes:

ORA-01461 can bind a LONG value only for insert into a LONG column

35198
compare known issues
Known Issue Issue ID

If the compare command specifies a WHERE clause that includes a column name containing one or more spaces, the spaces are removed in the WHERE clause in the query used in the comparison causing the comparison to fail.

 N/A
A compare of a partition can't be done if the partition is an Oracle hash partition. The compare can still be done on the whole table or with a specified where clause. SPO-20141
Compare/Repair using [schema].[table] may not work on AIX7.2 with Oracle19c due to establishing a network connection. SPO-20451
Compare will hang and the compare server will exit comparing table that has VARRAY containing UDT type. SPO-20733

 

Copy/ Append known issues
Known Issue Issue ID
If you need to copy a materialized view to a table, you should drop the target table before copying. Please be aware that the new target table created by copy will have an additional column named M_ROW$$ which does not exist on the source. The use of append on a materialized view to a table is not supported. 41679
The BINARY_FLOAT and BINARY_DOUBLE data types are not supported for the copy command. SPO-16453
Copy job status shows 'Locked' even when competed. SPO-20843
Conflict Resolution known issues
Known Issue Issue ID
The !ControlExtendedCharSet prepared conflict resolution routine and the !DEFAULT parameter currently cannot be used for generic conflict resolution. N/A
Partitioned Replication known issues
Known Issue Issue ID
When using a compound routing map in a placeholder route in the configuration file, do not use spaces between each routing component. For example, sysb@o.orab+sysc@o.oraC is correct because there are no spaces before or after the + symbol. N/A
Post will fail with ORA-14400 performing DML on partitioned table with VARAY residing in an OLTP compressed tablespace. SPO-20841
Capture known issue
Known Issues Issue ID
The SharePlex Capture process is getting stuck when users change the Oracle compatibility parameter from 11g to 12c. This issue is observed on the 12c 4 node RAC database. SPO-21339
 
Vertical and Horizontal Partitioning known issues
Known Issue Issue ID
When using horizontal partition replication with DATE data type in the column condition, the DATE needs to follow the SP date string format, 'MMDDSYYYYHH24MISS'. Otherwise, the Read and Compare processes are not able to process it. 55268
   

 

LOBs, VARRAYs, and XML known issues
Known Issue Issue ID
Users may encounter an out-of-sync condition when an UPDATE occurs on a table that contains a UDT with a VARRAY column, and there is no KEY on the table. This issue is specific to Solaris x86 operating systems. 29650
On Oracle 19c processing large n-items can lead to OOS and/or missing commits. SPO-20842

 

DDL Replication known issues
Known Issue Issue ID
Replicating CREATE ROLE (set param SP_OCT_REPLICATE_ALL_DDL 1) is changing the grantee name on the target to the name of the SharePlex Administrator. 2242
If the Capture process is behind in reading the Oracle redo or archive logs when the SP_OCT_REPLICATE_ALL_DDL parameter is enabled it will replicate DDLs whose time stamps precede this event. 56957
In replication from an Oracle source to a non-Oracle target, SharePlex does not support ALTER TABLE to add a number column in which the scale is larger than the precision. SPO-14372
In replication from an Oracle source to a non-Oracle target, SharePlex does not support ALTER TABLE...ADD COLUMN DDL operations when the column name is more than 30-bytes in length.

SPO-15585

 

Partition DDL known issues
Known Issue Issue ID
If separate SQL statements for partition DDL and index rebuild are run on the source, SharePlex only replicates the partition DDL and leaves target global index unusable. This is because ALTER INDEX is not supported by SharePlex. The recommended work around is that all partition DDLs which mark global indexes as unusable should be run with an appending clause UPDATE GLOBAL INDEXES to the ALTER TABLE SQL statements. The alternative is to manually rebuild the global indexes on target. 57939

 

Function based index known issues
Known Issue Issue ID
If there is more than one function defined in the index, SharePlex will choose the first. SharePlex cannot support multiple functions. 92931

 

Post to JMS known issues
Known Issue Issue ID

Replication of batch operations to ActiveMQ may cause a hang. The workaround is to set the SP_ORD_BATCH_ENABLE parameter to 0.

SPO-11335

If the post process that is writing to JMS is not on the same machine as the source database, and if the two machines are of different endianness, NCHAR data will not be written to JMS correctly. 107471

 

Post to non-Oracle targets known issues
Known Issue Issue ID

Replication of tables with varray columns from an Oracle source to a non-Oracle target can get out of sync because Oracle doesn't include key information on updates.

SPO-19048

Oracle Compression known issues
Known Issue Issue ID
Oracle 19c OLTP Compression. SharePlex does not support replication of DML operations on objects compressed using OLTP Compression in Oracle 19c. SPO-19793
Hybrid Columnar Compression. Activation will not fail if a table with “COMPRESS FOR QUERY LOW” compression is activated. Capture will log a message indicating that “COMPRESS FOR QUERY LOW” is not supported. 107487
Oracle 18c OLTP Compression. SharePlex does not support replication of DML operations on objects compressed using OLTP Compression in Oracle 18c. SPO-16449

Third-party known issues

Third-party known issues: Linux
Known Issue Issue ID
RHEL with 11g may encounter issues when producing core files. To work around this issue users will need to change the parameter "core_pattern" in the /proc/sys/kernel/core_pattern file. The following command enables core files: sysctl -w kernel.core_pattern=core. The original setting is: /corefiles/core. In this state, the system looks for a directory named /corefiles, which does not exist, therefore a core file could not be created. 54799
Third-party known issues: Oracle
Known Issue Issue ID
There is an Oracle issue that can cause SharePlex Capture to fail when replicating the OLTP compressed table that is having a column name with more than 30 characters. This is a known Oracle issue addressed under Oracle Bug 31776789. SPO-23856
There is an Oracle issue that can cause SharePlex Poster to fail when replicating the OLTP compressed table that is having a column with more than 30 characters. This is a known Oracle issue addressed under Oracle Bug 31786282. SPO-23509
Oracle may allow an invalid date, such as year 0000, to be inserted as the key value of a table without generating an error. This causes SharePlex to return an “Invalid DATE format detected in record with rowid” error when trying to insert the record to the target. SPO-1368
Users wishing to employ IOTs with overflow need to be running Oracle 11g or higher. This is a known Oracle issue addressed under Oracle Bug 4627859. 44626
On Windows systems, the Post process May exit when it encounters an "ORA-07445: exception encountered: core dump" error. Please refer to Oracle Bug 6658912 for more information and the Oracle provided work around. 67441
Oracle 11gR2 - During a SYNC job, the copy of a new table (without data) failed at “EXP-00011: table does not exist” . The table that failed is a new table without any data. The EXP-00011 is caused by 11gR2 new feature "Deferred Segment Creation" that is controlled by the initialization parameter DEFERRED_SEGMENT_CREATION. The default is ON. To avoid this error, disable the parameter. A tar has been opened with Oracle and Oracle created a note 960216.1 Original Export Raises EXP-11 Table Does Not Exist. 75179
OLTP compression with supplemental logging enabled may corrupt the Oracle Undo block, so Oracle suggests disabling supplemental logging when running OLTP compression. However, SharePlex requires supplemental logging to be enabled, so you may encounter this bug. This affects Oracle versions 11.2.0.2, 11.2.0.1 and 11.1.0.7. See Metalink ID 1191474.1. 92152
Sometimes the Post process will hang updating a SecureFile LOB. For more information please refer to Oracle tar SR 3-2898230851: OCILobWrite hangs at the OCI_LAST_PIECE for securefile LOB. N/A
There is an Oracle bug that can cause the database to crash when supplemental logging is enabled and transactions involving tables in a compressed tablespace are rolled back. Please refer to Oracle bug 8331063 for more information. N/A
A known issue in PL/SQL prevents the SharePlex conflict resolution logic from compiling the PL/SQL for tables whose names are the same as their owners. Oracle has stated that the issue will not be fixed. See Oracle TAR 2577886.996 for more information. This issue does not affect replication; SharePlex supports tables with identical owner and table names. N/A
Third Party Known Issues: Misc
Known Issue Issue ID
When replicating data from Oracle to SQL Server, the Microsoft SQL Server ODBC driver supports Owner names of up to 127 bytes only. SPO-14331
A known issue in EDB Postgres ODBC driver prevents support for emoji UTF-8 character set with EDB Postgres target. SPO-15251
