About the Informix Agent

The Informix agent monitors the Informix database processes. Specific agent operations include:

• Online---Starts the Informix database by using the following command:

  oninit
• Offline---Stops the Informix database by using the following command:

  onmode-ky
• Monitor--- Scans process table for oninit and, optionally, uses MonScript.

Detecting an Application Failure

By default, the agent faults if the monitor process cannot find an oninit process in the process table. By configuring the MonScript attribute to the provided OnstatTest.p1, the agent will fault if the monitor process does not detect the word "online" from the output of the command onstat -. When this happens, the entire database server service group switches to the next available system listed in the service group's SystemList attribute.
