Oracle GoldenGate – LOGALLSUPCOLS | NOLOGALLSUPCOLS

Use the LOGALLSUPCOLS and NOLOGALLSUPCOLS parameters to control the writing of supplementally logged columns specified with ADD TRANDATA or ADD SCHEMATRANDATA to the trail.

LOGALLSUPCOLS supports integrated Replicat (for Oracle database) and the Oracle GoldenGate Conflict Detection and Resolution feature (CDR). The supplementally logged columns are a union of the scheduling columns that are required to ensure data integrity across parallel Replicat threads and the conflict detection and resolution (CDR) columns. Scheduling columns are primary key, unique index, and foreign key columns. Including all of these supplementally logged columns satisfies the requirements of both CDR and dependency computation in parallel Replicat processing.

LOGALLSUPCOLS causes Extract to do the following with these supplementally logged columns:
Automatically includes in the trail record the before image for UPDATE operations.
Automatically includes in the trail record the before image of all supplementally logged columns for both UPDATE and DELETE operations.

NOLOGALLSUPCOLS is the default and prevents the supplementally logged columns from being written to the trail.
