For Informix, the SNMP environment is established by issuing
the following command, either before or after the database instance
is started:
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.
