If you get an SQL1042, you may want to have a look at the output from the db2diag command to figure out if something was logged during the operation. That can help you (or your DBA) to diagnose and fix the issue.
p.s: You should try to get a new DBA because SQLxxxxC are critical errors, which should be investigated. And those are the DBA's problem. If you get stuck, you can call IBM support and open a PMR to get this resolved.
