Some of the Oracle GoldenGate (OGG) Range Replicats abend with following error
ORA-00054: resource busy and acquire with NOWAIT
It happens if one of the Range Replicats applies DDL changes and during that brief moment when the other Range Replicats try to apply the same DDL changes as applied by the first Replicat it abends with ORA-00054: resource busy and acquire with NOWAIT
Try restarting the Replicat again to see if the status shows as “RUNNING”.
Also make sure that only one of the Range Replicat applies the DDL changes and include DDL EXCLUDE ALL in the other Range replicats to avoid this DDL duplication.
