OGG-00712
Updating I/O checkpoint after purging orphaned transactions on thread {0,number,0} with current position (Seq#: {1,number,0}, RBA: {2,number,0}).
Cause
A node failed and Extract could not capture the rollback. This causes the transaction to become orphaned. Because the TRANLOGOPTIONS parameter includes the PURGEORPHANEDTRANSACTIONS option, Extract validated that the transaction was orphaned and purged it. This message indicates that Extract is updating its checkpoint in consideration of the purge.
Action
None
