This chapter contains the requirements when capturing OLTP compressed data from an Oracle source database and replicating it to a supported target database.
The following operating systems are supported for capture from a supported Oracle database and replication to a supported target database.
SharePlex supports only the 64-bit version of the listed operating systems.
For OLTP, SharePlex supports the following operating systems only:
SuSE SLES 12.x and 15.x
Windows Server 2019 and 2022
SharePlex supports the Standard and Enterprise Editions of Oracle 12cR1, 12cR2, 18c, 19c, and 21c 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. 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. 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. 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.
|
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:
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 | |

SharePlex supports the following Oracle data types for replication to Oracle targets. See the Conditions of support for additional information.
Note: SharePlex supports columns that are defined as INVISIBLE.
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:
2. LONG and LOB (BLOB, CLOB)
SharePlex supports SecureFiles LOBs as follows:
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 or TRANSPORTABLE BINARY. 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.
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
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:
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'.
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.

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.

|---|---|
| CLOB | TEXT |
| NUMBER | INT, INTEGER, NUMBER |
| CHAR(n) | VARCHAR(n) |
| CLOB | VARCHAR(n) |

| 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.
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.

SharePlex supports the following data types for replication from PostgreSQL Database as a Service to Snowflake:
| PostgreSQL | Snowflake |
|---|---|
| TEXT | TEXT |
| INT | INT,INTEGER,NUMBER |

| TIMESTAMP | TIMESTAMP |
| TIMESTAMP_TZ | TIMESTAMP_TZ |
| BOOLEAN | BOOLEAN |
| TIME | TIME |
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.

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-8730 |
In SPUtils Task Manager on Windows, the port for Sp_CopSvr is visible, but the port details for the SharePlex processes started by Sp_CopSvr are not displayed. Workaround: Check for the SharePlex process connected to the specific port using sp_ctrl. This will display the processes associated with that port, showing their Cygwin PIDs. The corresponding Windows PIDs can be found using the ps command. |
SPUtils/Windows |
| SPSQL-8734 |
The PIDs displayed for all SharePlex processes in the sp_ctrl Status command output do not match the PIDs shown in the SPUtils Task Manager tab. Workaround: Execute the following command in the Command Prompt to view the Windows PID when the process is in a running state: ps -W | findstr <cygwin_pid> |
SPUtils Task Manager/Windows |
| 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-8400 |
In the Compare/Repair process, the row count in the Oracle table might be outdated because it is initially fetched from the system table sys.tab$, which is not updated in real-time and depends on the DB stats analyzer process. As a result, users may encounter the error source vs target table size difference too large incorrectly in some cases. Workaround: Either wait for the row count to be updated in the system table by the stats analyzer process, or use the override option as suggested. |
Compare/Repair |
| SPSQL-4858 | SharePlex displays the ORA-22990: LOB locators cannot span transactions error, and Compare results show out-of-sync data when users perform DML operations on data in replication after moving a LOB segment. This issue occurs during 23ai batch execution. | Compare |
| SPSQL-5664 | The Copy command fails on Windows machines due to the ORACLE_HOME environment variable not being populated correctly. | Copy command |
| SPSQL-4971 | The tables are going out of sync after performing DML operations through otest, and the CLOB column data is not being inserted during the script execution. | DML operations |
| SPSQL-5274 | SharePlex displays incorrect column names for schemas when the column name exceeds 30 characters on the source, in JSON and XML formats, during replication from Oracle to Kafka. | Kafka |
| SPSQL-4764 | The Poster process fails to replicate data from Oracle 19c to the file target after a Truncate operation is performed on the replicated data. This issue specifically affects tables containing BFILE and SDO_GEOMETRY columns. | Poster |
| 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-8303 | The Poster process stops due to an error after activation when a partial wildcard in the config file matches both SharePlex demo tables and user-created tables. | Poster |
| SPSQL-8404 |
The Poster process stops with an error when users try to replicate a horizontally partitioned table with a case-sensitive schema, table name, and a single partitioning scheme from the Oracle to the PostgreSQL database. Workaround: Create separate partitioning schemes for each target table name and create a separate entry for each table in the config file. |
Poster |
| SPSQL-8415 | The Snowflake Poster encounters a core dump issue when calling SQLDriverConnect from OdbcDriver::connect() for Snowflake connections. It also fails when running the snowflake_cleansp utility during a function call. This issue is observed with ODBC driver version 3.3 and above. | Poster |
| SPSQL-6104 | The SharePlex Poster process stopped due to an ORA-40441 error: JSON syntax error, triggered when users insert bulk JSON data for CLOB/NCLOB storage, which is stored as BASICFILE. | Poster |
| SPSQL-5630 | The Poster process stops due to an error when only the target table has a check constraint, and the inserted data violates that check constraint. | Poster |
| SPSQL-5454 | The SharePlex Poster process stops after activating the configuration for a hash partition on a target VM that has a '-' in its hostname. This issue is observed on the Windows platform. | Poster |
| SPSQL-5459 | When inserting the same rows multiple times into a table without a primary key and then updating all rows, an OOS (out-of-sync) error message appears in the Poster log. This issue occurs for both tables with normal names and table names longer than 30 characters during Oracle to PostgreSQL replication. | Poster |
| SPSQL-6117 | The undo_provision utility is not fully reverting all the changes made by the Provision utility. | Provision |
| SPSQL-5894 | When the Capture, Export, and Post queues have messages, and users run the Purge Config command, all queues are emptied as expected. However, error messages are observed in the source event logs. | Purge Config |
| SPSQL-5550 | When using the Query command 'job status "Error"', the status history for previous jobs with the "Error" status is not shown during Oracle to Oracle and PostgreSQL to PostgreSQL replication. | Query command |
| SPSQL-8019 |
SharePlex displays the error index row size 3040 exceeds btree version 4 maximum 2704 when users set the parameter SP_DEQ_USE_SP_CKSUM=1 and try to repair a table without a Primary Key (PK) during Oracle to PostgreSQL replication. Workaround:
|
Repair |
| SPO-21339 | 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. | Capture |
| SPO-16453 | The BINARY_FLOAT and BINARY_DOUBLE data types are not supported for the copy command. | Character Sets |
| SPO-20733 | Compare will hang and the compare server will exit comparing table that has VARRAY containing UDT type. | Compare |
| SPO-20451 | Compare/Repair using [schema].[table] may not work on AIX 7.2 with Oracle 19c due to establishing a network connection. | Compare |
| SPO-20843 | Copy job status shows 'Locked' even when competed. | Copy/ Append |
| SPO-21993 | While activating a config file with an Oracle SCN number, users are not able to delete a column in a DDL activity. | DDL Drop Column |
| SPSQL-8632 | The Copy command executes successfully, but when checking the status with the Job Status command, it displays Syncing instead of Done. | Job Status |
| SPSQL-8407 |
During Oracle to Kafka replication, the schema records of all tables are being replicated, not just the tables being replicated from Oracle to Kafka. Workaround: Set the schema value to 'no' to avoid sending the schema record. However, validate whether the schema record is used internally before applying this setting. |
Kafka |
| 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-20842 | On Oracle 19c processing large n-items can lead to OOS and/or missing commits. | LOBs, VARRAYs, XML |
| SPO-22342 | Performance issue is observed while performing the DML operations in bulk. | MySQL |
| SPSQL-4971 | The tables are getting out-of-sync after users perform bulk DML operations on the CLOB column data. This issue has been observed while working on Oracle 21c. | Oracle 21c |
| SPO-22517 | Performance issue is observed during replication while using partition table over the cloud. | Partition table |
| SPSQL-6609 | SharePlex displays an error when users attempt to create a database name in lowercase during pg_setup that matches an existing database name in uppercase on the system. | pg_setup |
| SPSQL-4982 | The SharePlex Poster process displays the Poster: execute select pg_replication_origin_create ('sp_post_xxxx_x'); failed error when creating an origin with logical replication for PostgreSQL to PostgreSQL replication. | Poster |
| SPSQL-5252 | The SharePlex Poster stops due to an error when attempting to resolve conflicts on VARCHAR columns in a PostgreSQL-Oracle bi-directional setup using a user-defined conflict resolution procedure. | Poster |
| SPO-24922 | SharePlex does not support the RAISE command on PostgreSQL databases. Poster stops with the Post stops error=-1 when trigger issues a RAISE [LABEL] error message. | RAISE command |
| SPSQL-5625 | SharePlex displays the Error encountered in remove_trigger objectid error when users attempt to disable or enable any trigger using the sp_pg_add_trigger.sql and sp_pg_remove_trigger.sql scripts for the given schema. | Trigger Scripts |
| 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. | varray columns |
| Issue ID | Known Issue | Component/ Feature |
|---|---|---|
| 29865658 | On Windows Server, Oracle 19c versions below 19.6 have an Oracle bug (29865658) that causes the SharePlex ora_setup, Reader, and Poster processes to get stuck. This bug is fixed in version 19.6 and later.To avoid this issue with SharePlex, either upgrade the Oracle 19c database to version 19.6 or higher. Users need to contact Oracle to obtain a patch for bug 29865658 or set the CLIENT_STATISTICS_LEVEL database parameter to 'OFF'. | Oracle |
| 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 issue is observed intermittently on Oracle 21c. 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 |
| 44626 | Users wishing to employ IOTs with overflow need to be running Oracle 11g or higher. This is a known Oracle issue addressed under 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 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. Please see 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.
