"PDML child %s %s %s for parent %s %s %s cannot be skipped."
*Cause: A request was made to skip a parallel DML child transaction id.
This is not supported.
*Action: Using the DBMS_LOGSTDBY.UNSKIP_TRANSACTION procedure, remove
the child transaction id, then specify the parent transaction id
using DBMS_LOGSTDBY.SKIP_TRANSACTION if appropriate.
