How To Fix HH036 - Edit the Informix ONCONFIG file

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 036

• Message text: Edit the Informix ONCONFIG file

What causes this issue?

You defined ONCONFIG parameter 'BUFFERS' to be less than the
recommended minimum value.
'BUFFERS' defines the size of the database buffer in shared memory,
or, to be more precise, defines the number of pages. The value
'BUFFERS * pagesize' (page size can be determined from the output of
the shell command 'oncheck -pr') should not be less than the
specified minimum value (exception: main memory of the DB server is
very small or is used elsewhere). A small configuration of
'BUFFERS' results in a high displacement rate in the buffer, that is
in loss of performance. As a rough formula for dimensioning the
database buffer, define 20% of the physical memory (see Note 38307).

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

System Response

How to fix this error?

To configure 'BUFFERS' larger, edit (as user 'informix')
file '$INFORMIXDIR/etc/$ONCONFIG'.
CAUTION: The change only becomes active after starting up the database.
