OGG-01959
Failed to validate table {0}. The IOT is created with the COMPRESS option to use key compression. This is not supported by Oracle GoldenGate and prevents further redo capture.
Cause
The index-organized table is created with key compression. Oracle GoldenGate does not support IOTs with key compression.
Action
Remove the table from the Extract and Replicat configurations, and then restart the processes.
