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

For OLTP, SharePlex supports the following operating systems only:
CentOS Linux 7.x and 8.x
SuSE SLES 12.x and 15.x
HP-UX 11.31 Itanium
SharePlex supports the Standard and Enterprise Editions of Oracle 12cR1, 12cR2, 18c, and 19c for replicating the OLTP compressed data.
SharePlex supports DML operations on tables and sequences, with some conditions. DML can be replicated from an Oracle source to an Oracle or an open 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.
SharePlex supports the following DML operations on tables:
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:
|
|
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:
*SharePlex does not support the following for any table type:
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 |
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:
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.
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:
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

For CREATE MATERIALIZED VIEW the following applies:
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.
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.
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.

| 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.
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.

The target table must support the column types that are being replicated from the source PostgreSQL table.
|
Limitation: In PostgreSQL to Oracle replication, in the source database table and column names are created in lower case by default, and in the target database they are created in upper case. In such a case, if we configure such tables in replication with the source table name in lower case with a double quote and the target table name in upper case with quotes in the configuration file, in the Post process, while creating a query, the table name is used in upper case as specified in the configuration file, but column names are used in lower case by default. Hence, this query fails in execution as the target table contains column names in capital letters. The scenario will work fine if the target table or column name is created in lower case using double quotes in the database and the target table name is specified in small case in the configuration file. |

| Issue ID | Known Issues | Component/ Feature |
|---|---|---|
| SPSQL-3596 |
An Oracle custom routine does not take priority over a SharePlex prepared routine in PostgreSQL to Oracle bi-directional replication when !DEFAULT is specified/used in the conflict resolution file. Workaround: Change the sequence of routines in the conflict resolution file. Mention the custom routine first, followed by Shareplex Prepared Routine. Example: Instead of !DEFAULT IUD !LeastRecentRecord(col_name) !DEFAULT IUD schemaName.ProcedureName
Use !DEFAULT IUD schemaName.ProcedureName !DEFAULT IUD !LeastRecentRecord(col_name) Note: We are planning to resolve this issue in SharePlex 11.1 version. |
BDR |
| SPSQL-3255 |
Updating conflict resolution fails when SharePlex performs multiple updates using MostRecentRecord and LeastRecentRecord routines. This issue is observed in PostgreSQL to PostgreSQL and PostgreSQL to Oracle bi-directional replication. Note: We are planning to resolve this issue in SharePlex 11.1 version. |
BDR |

| SPSQL-3024 | The vulnerability issue (CVE-2022-1471) is observed in the snakeyaml-1.32.jar SharePlex PostgreSQL library. This issue was found during the WhiteSource scan. Currently, there are no fixes available for this issue as per the National Vulnerability Database. | SharePlex PostgreSQL library |
| SPO-24687 | SharePlex does not replicate data when the table or column name in replication has more than 30 characters. | Open targets |
| SPO-24119 | SharePlex Poster is displaying the ODBC Driver Invalid precision value error when replicating the BLOB data type with the data size of more than 8000 bytes. | SQL Server |

| SPO-20843 | Copy job status shows 'Locked' even when competed. | Copy/ Append |
| SPO-20842 | On Oracle 19c processing large n-items can lead to OOS and/or missing commits. | LOBs, VARRAYs, XML |
| SPO-20841 | Post will fail with ORA-14400 performing DML on partitioned table with VARAY residing in an OLTP compressed tablespace. | Partitioned Replication |

| SPO-20451 | Compare/Repair using [schema].[table] may not work on AIX7.2 with Oracle19c due to establishing a network connection. | Compare |
| SPO-20205 | Oracle to Kafka supported data format: Kafka replicates the varray column data only in the XML format. Currently, Kafka does not replicate the varray column data in the JSON format. |
Kafka |
| SPO-19048 | 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. | Post to non-Oracle targets |
| SPO-16453 | The BINARY_FLOAT and BINARY_DOUBLE data types are not supported for the copy command. | Character Sets |
| SPO-15585 | 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. | DDL Replication |
| 107487 | 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. | Oracle Compression |
| 107471 | 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. | Post to JMS |

| 61713 | 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. | ASM |
| 57939 | 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. | Partition DDL |
| 56957 | 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. | DDL Replication |
| 55268 | 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. | Vertical and Horizontal Partitioning |
| 41679 | 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. | Copy/ Append |

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: |

| 29650 | 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. | LOBs, VARRAYs, XML |
| 2242 | 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. | DDL Replication |
| N/A | 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. | General |
| N/A | 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. | ASM |

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 & |

| 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 |
| 44626 | 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. | Oracle |
| 53701 | There is a known issue with INSERT DIRECT LOAD VALUES (IDLV) in Oracle 11g that prevents the reading or modification of an object after modifying it in parallel. Oracle has provided three (3) solutions for addressing this issue. They can be found in the Oracle update of SR6849411.993 dated 05-07-2008. This issue was fixed by Oracle in 11gR2 | Oracle |
| 59258 | Oracle versions 10.2.0.1 through 11.1.0.6 on AIX 5.3 (64 bit), members of SharePlex Admin group, other than the installation user, cannot run ora_setup or start SharePlex. This is an Oracle issue. Please refer to Oracle Bug# 6800649 and apply Patch 6800649. | Oracle |
| 75179 | 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. | Oracle |
| 92152 | 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. | Oracle |
| N/A | 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. | Oracle |
| 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. | Oracle |
| 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. | Oracle |
