DB2 FOR LUW / DB2FORLUW / A50 - DB2

This APAR applies if a database is configured to use a userexit
program to archive logs.

In very rare cases, IBM Db2's log writing EDU may still be
writing to a log file as Db2 invokes the userexit program.  No
warning or error message is produced.  Instead, the log file is
archived as a corrupt log file.

To detect such a case, IBM recommends users add code to their
userexit programs to verify the log archived, with the db2cklog
utility.  If the db2cklog responds with:

DBT7087W  The db2cklog utility found information in the current
log file which indicates that the log file might be active.

then Db2 has hit this APAR and the archived log file is corrupt.
