A v8.01 database on AIX 5.3 (both will be upgraded in the coming days) gives me serious errors when I run db2dart on it. Errors are on some indexes and LOB tables. All data entry operations on this database were done with JDBC, and no exceptions were returned, so these errors are a complete surprise.
Are there fixing tools/procedures for such problems?
What should be my next step?
Below are a few snippets from the report.
Thanks for any help you can give me.

Re: Please help with corrupted database2012-12-11T15:37:24Z in response to SystemAdminDo you have any database backups or have you attempted to perform a database backup?
Index corruption can be fixed by marking the index as bad (using db2dart /mi option) and then rebuilding it.
LOB corruption - you can try to do a table reorg with longlobdata option.
