Troubleshooting
Problem
Latency can grow significantly if InfoSphere CDC for Oracle databases is processing many ROLLBACK entries in a large transaction from the Oracle redo log. ROLLBACK entries are logged with the following types of operations: -- INSERT / UPDATE / DELETE with constraint violation (except NOT NULL constraint) -- ROLLBACK TO SAVEPOINT -- ROLLBACK
Symptom
Replication is slow with high or increased latency.
