How To Fix HH035 - Edit the Informix ONCONFIG file

SAP Error Message - Details

• Message type: E = Error

• Message class: HH - (Long) text for check tool 'infcfgcheck'

• Message number: 035

• Message text: Edit the Informix ONCONFIG file

What causes this issue?

You configured ONCONFIG parameter LOGSIZE differently from the
recommended value.
The recommended value is only a guide value, since other factors
(logical log backup, checkpoints, long transaction, ...)
are relevant when choosing the 'right' size
(for details, see 'Informix Administration Guide,
Vol. 1, chap. 'Logical log'').
This single check is primarily intended for consideration purposes,
since a good configuration of LOGSIZE also results in a better
performance (especially if LOGSIZE is set very small and was
increased).

System Response

How to fix this error?

To reconfigure LOGSIZE, edit (as user 'informix')
file '$INFORMIXDIR/etc/$ONCONFIG'.
CAUTION: The change only becomes active when the database is started
up.
