When the database catalog was migrated to UNICODE, some triggers could not be recreated. The database system created replacements for these triggers.
In the MIGRATIONERRORPROTOCOL system table, check the CREATE statements for the triggers that could not be recreated. The CREATE statement for a trigger can be incorrect for the following reasons (for example):
The trigger is referencing a table or view that was renamed or does not exist any more.
The syntax within the trigger has changed.
You can delete the replacement trigger once you have fixed the original one.
