Database Monitor Troubleshooting for
Informix
For Informix, the SNMP environment is established by issuing the
following command, either before or after the database instance is
started:
onsrvapd -rall -k0
onsrvapd is the Informix daemon, which launches the Informix SNMP
subagent (onsnmp), if there is an Informix database instance running on
the node. If there is no Informix instance running, onsnmp will not be
started.
Normally, onsnmp starts and stops when a database instance is invoked.
However, by specifying -k0 on the command-line, the subagent remains
active even if the database is shutdown. The -rall option ensures that
frequent updates to the Informix MIB are made. Please consult your
Informix documentation for details on the frequency of these updates or
contact Informix support.
