solve
This error is due to not recognize the tag in the new version of the old version backup lead, so we need to clean up the old version of the tag and back up again in the new version.
Now that can not see the name tag normal, we select Remove tag directly from the underlying table and restart the DTM. Proceed as follows,
- Stop the database
sqstop abrupt
- Delete DTM related tables
disable 'TRAF_RSRVD_5:TRAFODION._DTM_.MUTATION'
disable 'TRAF_RSRVD_5:TRAFODION._DTM_.SNAPSHOT'
disable 'TRAF_RSRVD_5:TRAFODION._DTM_.LOB_META_SHADOW'
disable 'TRAF_RSRVD_5:TRAFODION._DTM_.MUTATION_SHADOW'
drop 'TRAF_RSRVD_5:TRAFODION._DTM_.MUTATION'
drop 'TRAF_RSRVD_5:TRAFODION._DTM_.SNAPSHOT'
drop 'TRAF_RSRVD_5:TRAFODION._DTM_.LOB_META_SHADOW'
drop 'TRAF_RSRVD_5:TRAFODION._DTM_.MUTATION_SHADOW'
- Start the database
sqstart
- Revalidate View tag command
SQL>get all backup tags;
