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 9.4.x/10.x.

Versions with interoperability for Oracle database as a source

The following SharePlex versions are interoperable for Oracle database as a source, including the Compare/Repair feature:

  • 9.4.x
  • 10.0.x
  • 10.1.x
  • 10.2

Notes:

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

Oracle source basic conditions of support

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
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 data types to ensure successful DML operations.
  • If the precision or size of the target data type 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)

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.

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.

Oracle to open targets DDL support

SharePlex provides default and optional DDL support.

Notes: 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

SharePlex provides limited DDL support for replication from Oracle to open targets. 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 cross platforms.

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:
  • TRUNCATE TABLE is not supported from Oracle compressed objects to open targets.

  • The default mappings of Oracle data types to their open target counterpart for replicated ALTER TABLE ADD COLUMN DDL are shown in the "Supported Data type" section of the respective target. When adds the column, it defines it with the default data type. This mapping applies to the entire configuration (not per table).

Conditions of support
  1. Because Oracle and MySQL handle this data type differently, there may be a very small difference in precision between the value of the source and the value of the target row. You may see the difference when viewing the data from SQL*Plus or other utility, but SharePlex will not report this difference as an out-of-sync condition.
  2. If the MySQL target database is earlier than version 5.6.4, the fractional seconds will be truncated. Earlier versions did not support fractional seconds.

See Conditions of support for the additional conditions of support for the above-mentioned supported data types.

Supported data types

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. Conditions of support - 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. Conditions of support - 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. Conditions of support - NCLOB

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

4. Conditions of support - 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. Conditions of support - 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. Conditions of support - 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.

Supported operations and objects for DDL replication

SharePlex provides default and optional DDL support.

Note: 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
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.
  1. For CREATE TABLE AS SELECT, SharePlex supports the following data types: LONG, DATE, RAW, LONG RAW, ROWID, LONG VARCHAR, CHAR, CLOB, BLOB, CFILE, BFILE, TIMESTAMP, INTERVAL YEAR TO MONTH, INTERVAL DAY TO SECOND, VARCHAR2, NUMBER, and ANYDATA.
  2. For CREATE MATERIALIZED VIEW the following applies:

    • SharePlex supports the following data types 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, VARCHAR2, NUMBER, 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.
  3. 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.

  4. 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.

Oracle to Snowflake replication

SharePlex supports replication from Oracle to Snowflake, according to the details below.

Supported operating systems

SharePlex replicates remotely to Snowflake. Remote replication from the following operating systems is supported:

Red Hat Linux version 7.x, 8.x

Note: SharePlex Snowflake supports only the 64-bit version of the listed operating systems.

Supported target versions and ODBC requirements

Snowflake 6.31 Enterprise, Community version

ODBC driver requirement: Snowflake 2.25.10

Note: If you cannot use ODBC 2.25.10, use the ODBC 2.24.2 version instead.

Limitations:

The following ODBC driver related limitations are observed while replicating data from Oracle to Snowflake:

Supported target cloud platforms

Microsoft Azure

Supported data types

SharePlex supports the following data types for replication from Oracle to Snowflake:

Oracle Snowflake
CLOB TEXT
NUMBER INT, INTEGER, NUMBER
CHAR(n) VARCHAR(n)
CLOB VARCHAR(n)
NCHAR CHAR(n)
VARCHAR2(n) VARCHAR(n)
CLOB VARCHAR(n)
NCLOB TEXT
CLOB VARCHAR(n)
LONG TEXT
BLOB BINARY, VARBINARY
RAW(n) VARBINARY
LONGRAW VARBINARY
BINARY_FLOAT REAL
NUMBER SMALLINT
NUMBER BIGINT
NUMBER NUMERIC, DECIMAL
DATE DATE
BINARY_DOUBLE DOUBLE PRECISION
TIMESTAMP TIMESTAMP
TIMESTAMP_TZ TIMESTAMP_TZ

Note: It is anticipated that the Snowflake DB's default "HEX" format for binary type will be maintained for Oracle binary to Snowflake binary data type replication. Since source Oracle DB binary data is stored only in "HEX" format, Shareplex does not guarantee data integrity for any other format.

Conditions of support
  • Char(n) data type - In Oracle, Char(n) is a fixed-size data type. If you insert char data with a length less than "n" into the "Char(n)" column, the remaining slots (n - length) are padded with space to occupy the complete "n" memory positions. Snowflake uses  VARCHAR(n) for char storage since Snowflake lacks a comparable fixed-length character data type and only saves char data up to its length. Live replication will ensure that char column data is correctly copied. However, if users are manually inserting data into Snowflake for the equivalent of a Char(n) Oracle column, then the user will need to handle padding as well to occupy the full "n" length so that data will be in sync in both the source and target DB.

  • Binary & Text data types - Snowflake Binary & Text data types have size limitation of 8 MB, so Oracle’s advance Data type replication will be restricted to max 8 MB size limit of equivalent counterpart. Refer table below.

Oracle Data type Max Size Snowflake Data type Max Size
LONG 2 GB TEXT 8 MB of unicode chars
CLOB 4 GB TEXT 8 MB of unicode chars
LONGRAW 2 GB BINARY or VARBINARY 8 MB
BLOB 4 GB BINARY or VARBINARY 8 MB

See Conditions of support for the additional conditions of support for the above-mentioned supported data types.

Supported operations and objects for DML replication

SharePlex supports DML operations on tables, with some conditions. DML can be replicated from an Oracle source to a Snowflake target.

Tables

SharePlex supports the following DML operations on tables when replicating data from an Oracle source to the Snowflake target:

  • Singular and bulk operation - Insert with key(s)/ non key(s)

  • Singular and bulk operation - Update with key(s)/ non key(s)

  • Singular and bulk operation - Delete with key(s)/ non key(s)

Limitations:

The following DML operations related limitations are observed while replicating data from Oracle to Snowflake:

  • Slowness while performing DML operations

    • Single Insert: Frequent commits and rollbacks can cause slowness in replication.

    • Batch Inserts: Insert with advance data types [target Snowflake data types: TEXT and BINARY] can cause significant slowness in replication for data with plain text or binary JSON and XML.

    • Single Update and Delete : Frequent commits and rollbacks can cause slowness.

    • Batch Update and Delete: The Snowflake ODBC driver does not support batching of transactions. It can cause significant slowness in replication.

For additional information, see Supported Operations and Objects for DML Replication.

PostgreSQL Snowflake
TEXT TEXT
INT INT,INTEGER,NUMBER
CHAR(1:2000) VARCHAR(n)
CHAR(2001:) VARCHAR(n)
CHAR(n) CHAR(n)
VARCHAR(1:4000) VARCHAR(n)

BIGINT BIGINT
NUMERIC (whole number without fraction) NUMERIC, DECIMAL
NUMERIC (fractional number) FLOAT
DATE DATE
DOUBLE PRECISION DOUBLE PRECISION
TIMESTAMP TIMESTAMP
TIMESTAMP_TZ TIMESTAMP_TZ
BOOLEAN BOOLEAN
TIME TIME
Conditions of support
  • Char(n) data type - In PostgreSQL, Char(n) is a fixed-size data type. If you insert char data with a length less than "n" into the "Char(n)" column, the remaining slots (n - length) are padded with space to occupy the complete "n" memory positions. Snowflake uses  VARCHAR(n) for char storage since Snowflake lacks a comparable fixed-length character data type and only saves char data up to its length. Live replication will ensure that char column data is correctly copied. However, if users are manually inserting data into Snowflake for the equivalent of a Char(n) PostgreSQL column, then the user will need to handle padding as well to occupy the full "n" length so that data will be in sync in both the source and target database.

  • Text data types - Snowflake Text data types have size limitation of 8 MB, so PostgreSQL’s TEXT data type replication will be restricted to max 8 MB size limit of equivalent counterpart. Refer table below.

PostgreSQL Data type Max Size Snowflake Data type Max Size
TEXT unlimited TEXT 8 MB of unicode chars

See Conditions of support for the additional conditions of support for the above-mentioned supported data types.

  • Singular and bulk operation - Update with key(s)/ non key(s)

  • Singular and bulk operation - Delete with key(s)/ non key(s)

Limitations:

The following DML operations related limitations are observed while replicating data from PostgreSQL to Snowflake:

  • Slowness while performing DML operations

    • Single Insert: Frequent commits and rollbacks can cause slowness in replication.

    • Batch Inserts: Insert with advance data types [target Snowflake data types: TEXT and BINARY] can cause significant slowness in replication for data with plain text or binary JSON and XML.

    • Single Update and Delete : Frequent commits and rollbacks can cause slowness.

    • Batch Update and Delete: The Snowflake ODBC driver does not support batching of transactions. It can cause significant slowness in replication.

      • Batch Update and Delete: The Snowflake ODBC driver does not support batching of transactions. It can cause significant slowness in replication.

    For additional information, see Supported Operations and Objects for DML Replication.

    Supported operations and objects for DDL replication

    Currently, SharePlex does not support DDL operations when replicating data from a PostgreSQL Database as a Service as source to a Snowflake target. It only supports tables as objects for data replication.

    Known Issues in this Release

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

    Issue ID Known Issues Component/ Feature
    SPSQL-5252

    In the bi-directional replication of data from PostgreSQL 14.7 Google Cloud Platform to Oracle, the Poster process stops with an error when a user-defined procedure tries to resolve the conflicts that occurred on columns with a VARCHAR data type.

    This issue is observed if the update statement is triggered simultaneously in the same row on both source and target.

    Bi-directional replication
    SPSQL-4982 When there are multiple Named Queues set up in replication, after activating the config, the SharePlex Poster process displays the execute select pg_replication_origin_create ('sp_post_2600_7'); failed error upon its initial startup. However, after displaying the error, SharePlex automatically restarts the Poster process to resolve the issue. Poster
    SPSQL-4981

    The SharePlex Poster process abruptly stops with the Can't find object id error when the SP_OPX_THREADS parameter is set to a higher number of threads that the system does not support.

    Example: Number of CPU(s): 4, Thread(s) per core: 2, Core(s) per socket: 2. Therefore, the optimal value for the SP_OPX_THREADS parameter is 4, with a maximum of 3 Post processes in a single server.

    Workaround: Reset the SP_OPX_THREADS parameter to a lower value than the previous setting and restart the Poster process.

    SPSQL-4854

    The SharePlex Poster displays an error regarding the invalid length for a variable character string while replicating CLOB column data from Oracle to Oracle. This issue has been observed while working on Oracle 19c on the RHEL platform, and Oracle 21c.

    Affected versions: SharePlex 10.2, 11.0, 11.1, and 11.2 on the Linux platform.

    Oracle to Oracle
    SPSQL-4909 SharePlex displays a value in the TARGET_ROWID column of the shareplex_conf_log table even when the user sets the parameter SP_OPO_LOG_CONFLICT to 1. This issue is observed while replicating data from PostgreSQL to Oracle and Oracle to Oracle. PostgreSQL to Oracle and Oracle to Oracle.
    SPSQL-3596 In bi-directional replication of data from PostgreSQL to Oracle, an Oracle custom routine (splex.PROCEDURE1) is not taking priority over a SharePlex-prepared routine. On the contrary, the SharePlex-prepared routine (LeastRecentRecord) is taking priority over the custom procedure on Oracle Peer for conflict resolution. PostgreSQL-Oracle BDR
    SPO-24757

    SharePlex displays the “ORA-04036: PGA memory used by the instance exceeds PGA_AGGREGATE_LIMIT” error while performing the Compare/Repair operation on the XML data.

    Workaround:

    1. Upgrade Oracle to 19.19 DBRU

    2. Set appropriate PGA_AGGREGATE_LIMIT using the below Oracle suggested script :

      WITH

      MAX_PGA as

      (select round(value/1024/1024,1) max_pga from v$pgastat where name='maximum PGA allocated'),

      MGA_CURR as

      (select round(value/1024/1024,1) mga_curr from v$pgastat where name='MGA allocated (under PGA)'),

      MAX_UTIL as

      (select max_utilization as max_util from v$resource_limit where resource_name='processes')

      SELECT

      a.max_pga "Max PGA (MB)",

      b.mga_curr "Current MGA (MB)",

      c.max_util "Max # of processes",

      round(((a.max_pga - b.mga_curr) + (c.max_util * 5)) * 1.1, 1) "New PGA_AGGREGATE_LIMIT (MB)"

      FROM MAX_PGA a, MGA_CURR b, MAX_UTIL c

      WHERE 1 = 1;

    SR 3-33906406631 After moving the LOB segment, users may encounter an 'ORA-22275' or 'ORA-22990' Oracle error when performing DML operations. Additionally, the Compare result may be displayed as out of sync. This intermittent issue has been observed on Oracle 21c. This is a known Oracle bug. See Oracle bug report SR 3-33906406631. Oracle
    101806 When replicating data from Oracle to MySQL, SharePlex Poster displays an error after performing the Update operation on columns with the data type integer and column values that are multiples of 1000. This issue is related to a defect in the MySQL database: https://bugs.mysql.com/bug.php?id=101806 MySQL
    54799 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. Linux
    125639 There might be an issue when replicating VARRAYs with FLOAT(n) type to a target machine running Oracle 10g, due to the way that Oracle handles Float(n) types. Float is not an Oracle type; it is a SQL-92 type and Oracle is not consistent in the way that it handles the float type. This is a known Oracle bug. See Oracle bug report 4266304. Oracle
