Database Marked Bad

Scott Jones

Hello,

In an attempt to save disk space, I went in and gzipped all of the log
files for my database running DB2 version 7.2 . This resulted in the
database being marked bad because a log file was no longer found (I
think).

Here is an excerpt from db2diag.log:

String Title:sqleMarkDBad: PID:7980 Node:000

I have a backup that is pretty old and all of the log files so I can
rollforward, but was wondering if there is a way since I actually HAVE
the ability to recover -- it just may take me a while.

Is there a way that I can use the dump files that are mentioned in the
line after the "marking the database bad" error message in order to
make my log file useable again? Every time I attempt to connect to
the database, I get a generic system error:
SQL1042C An unexpected system error occurred. SQLSTATE=58004

It apparently tries to do a crash recovery but fails:

If there is a way to fix the current database, using some of these
dump files, that'd be wonderful. Thanks for any suggestions anyone
has.

Sincerely,

What happens if you stop the database, unzip the logfiles and start the
db again?

If you have a backup copy of your database before the problem, you
may restore the backup copy..
If you dont, check with system restore(in case of windows..) you can
take backup copy and restore it !
