By default, SharePlex replicates some Oracle DDL for objects that are listed in the active configuration (explicitly or by wildcard), but you can expand this support with parameter settings.
Important!
SharePlex provides default DDL support for objects in the configuration file. You can expand this support through parameter settings.
See the SharePlex Release Notes for detailed information about the DDL that is supported by SharePlex.
SharePlex provides some basic DDL support by default.
By default SharePlex replicates:
ALTER TABLE to:
ADD, MODIFY, DROP, SPLIT, COALESCE, MOVE, TRUNCATE, EXCHANGE PARTITION/SUBPARTITION
ADD, MODIFY, or DROP columns
when:
This functionality is controlled by the SP_OCT_REPLICATE_DDL parameter. The valid values are as follows:
0 (disable replication of both ALTER TABLE and TRUNCATE)
1 (enable ALTER replication only)
2 (enable TRUNCATE replication only)
3 (enable replication of ALTER and TRUNCATE)
By default, the SharePlex Auto-Add feature is also enabled to provide DDL support for tables and indexes that are created after activation. When SharePlex detects a CREATE statement for one of these objects and its name satisfies a wildcard in the configuration file, SharePlex does the following:
The Auto-Add feature is controlled by the SP_OCT_AUTOADD_ENABLE parameter, which is set to 1 (enabled) by default.
See the SharePlex Reference Guide for details about this parameter.
You can enable the replication of the following DDL when it is issued on objects that are in the configuration file. To enable the replication of a DDL command, set the associated parameter to 1.
| DDL command | Set this parameter to 1 |
|---|---|
| CREATE / DROP TRIGGER | SP_OCT_REPLICATE_TRIGGER |
| CREATE / DROP SYNONYM | SP_OCT_REPLICATE_SYNONYM |
| GRANT | SP_OCT_REPLICATE_GRANT |
See the SharePlex Reference Guide for details about these parameters.
You can expand Auto-Add support to include any of the object types listed in the following table. The object is added to replication if its name satisfies a wildcard specification in the active configuration file.
To enable auto-add of individual object types
Set the appropriate parameter to 1, using the following table as your guide.
| DDL to auto-add | Parameter to set to 1 | Additional requirements |
|---|---|---|
| CREATE / DROP SEQUENCE | SP_OCT_AUTOADD_SEQ |
Set the SP_SYS_TARGET_COMPATIBILITY parameter to at least 8.6.3. |
| CREATE /DROP MATERIALIZED VIEW* | SP_OCT_AUTOADD_MV |
Set the SP_SYS_TARGET_COMPATIBILITY parameter to at least 8.6.2. |
* SharePlex does not replicate materialized views to materialized views. 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 replicates DROP MATERIALIZED VIEW, but not ALTER MATERIALIZED VIEW. See the SharePlex Reference Guide for details about these parameters.
You can configure SharePlex to replicate DDL for certain objects that are not listed in the configuration file. SharePlex replicates the DDL statements, but does not replicate any data change operations made to the objects because they are not part of active replication. Therefore, SharePlex does not maintain synchronization of these objects on the target. The objects must exist in the source and target prior to configuration activation.
NoteS:
|
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 not only to the object that is outside the replication configuration, but also to the underlying objects that are in replication. |
|
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 to work around this issue:
|
To replicate DDL for objects outside the replication configuration
Set the SP_OCT_REPLICATE_ALL_DDL parameter to 1.
See the SharePlex Reference Guide for details about this parameter.
See the SharePlex Release Notes for more information about supported DDL for objects that are not in the configuration file.
