Hello, we have a HP-3000, using minisoft's ODBC for our Web Portal applications.

Yesterday, we received a turbo-image error, indicating our database transaction log file had reached its maximum number of user processes.
Doing some research via DBAUDIT, I discovered one of our web applications did indeed have a large number of transactions.

I found the following article on the FAQ section of the HP3000-L list:



Concurrent accessors when using database logging on the HP3000





Due to limits in MPE's internal tables, the maximum number of processes that can share a log process -- which in this case means the maximum number of processes that can open a database with modify-access -- is 1140. Beware of this on limit on large systems.

My question:  If I break-out the transactions from our heaviest web application (the heaviest one is from a separate database) into a separate db transaction log file (currently one log file shares a number of different database transactions), will this help reduce the number of problems with the above mentioned limitation?
