DB2: The transaction log for the database is full, But there is no 'First active log file'

Question

First, I wish to say that I have very little experience with DB2. However, I've been tasked with tracking down the problem and solution to this problem.

This is a DB2 database, and our testers are saying that they get:

The transaction log for the database is full.. SQLCODE=-964, SQLSTATE=57011, DRIVER=4.13.127 SQL Code: -964, SQL State: 57011

I did increase the number of LOGPRIMARY to '40'. However, it appears that the transaction logs are still full. I then decided to 'prune' the transaction logs. The procedure I have is to Prune all prior to the active transaction log. However, I cannot determine the active log:

$ db2 get db config for MyDB | grep -i 'log'

 Log buffer size (4KB)                        (LOGBUFSZ) = 1997

$

I do note that the transaction log files do appear in /home/db2/db2inst1/db2inst1/NODE0000/SQL00001/LOGSTREAM0000/.

Is transaction logging correctly setup ? Would increasing the logs be the answer? Or should I push back on the users to encourage them to do more commits?
