Copied from DB6 597

What causes this issue?

This value is the maximum fill level (in percent) of the secondary log
area since the system was started or since the last monitor reset.

System Response

The more secondary log area that needs to be added, the worse
performance is. If the secondary log area is full, it means
transactions are terminating due to insufficient log area. As it is
these transactions that have logged a large number of changes,
resetting them can be expensive.

How to fix this error?

If an error occurs, you can extend the log area by increasing the
maximum number of log files:
<LB>UPDATE DB CFG USING LOGPRIMARY <value></> (primary log files)
<LB>UPDATE DB CFG USING LOGSECOND <value>,,</> (secondary log
files)
You can also extend the log area by increasing the size of individual
files:
<LB>UPDATE DB CFG USING LOGFILSIZ <value>,,</> (parameter
LOGFILSIZ)

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
