Last updated on JULY 31, 2020

Applies to:

Oracle GoldenGate - Version 12.1.2.0.0 to 12.3.0.1.0 [Release 12.1 to 12.3]
Information in this document applies to any platform.

Symptoms

If there are multiple DDLs executed on a table in a short period, extract may need to generate multiple TDRs for the same table within one millisecond. When this occurs, the generated TDRs have the same timestamp.This leads to issue downstream because pump or replicat fails to invalidate the table metadata when needed.

Note:
TDR (Table Definition Record) is a definition info of table and columsn, and those are written in trail file.

 

Changes

Multiple DDLs are executed on a table within sub-millisecond apart.
