DDL EXCLUDE ALL

DDL EXCLUDE ALL is a special processing option that is intended primarily for Extract. DDL EXCLUDE ALL blocks the replication of DDL operations, but ensures that Oracle GoldenGate continues to keep the object metadata current. When Extract receives DDL directly from the logmining server (triggerless DDL capture mode), current metadata is always maintained.

You can use DDL EXCLUDE ALL when using a method other than Oracle GoldenGate to apply DDL to the target and you want Oracle GoldenGate to replicate data changes to the target objects. It provides the current metadata to Oracle GoldenGate as objects change, thus preventing the need to stop and start the Oracle GoldenGate processes. The following special conditions apply to DDL EXCLUDE ALL:

  • DDL EXCLUDE ALL does not require the use of an INCLUDE clause.

  • When using DDL EXCLUDE ALL, you can set the WILDCARDRESOLVE parameter to IMMEDIATE to allow immediate DML resolution if required.

To prevent all DDL metadata and operations from being replicated, omit the DDL parameter entirely.
