I would like to know how other people are handling the backups of the
Informix logical logs.

It appears that you can not use ADSM because the logical log names are never
reused so they never go inactive and thus never expire. Unfortunately, I
can't find an ADSM command which will delete a specific file (rather than a
filespace) so I can't simply delete the old ones.

Is there any way to use ADSM to backup the logical logs and not retain them
forever?
