Is there an option to only log specific databases to the LXX, e.g., CA 7 not CA 11?
There is not an option to log specific databases for the Log File (LXX). CA 7 performs logging to the LXX. CA 11 does not.
If you are going to share the MUF with both products, you will need to perform logging for both.
If you do not want CA 11 to perform logging, you will need to use a different MUF for CA 11.
