Operations of the Oracle 9iAS Application Server Probe

The Oracle 9iAS Application Server probe checks the following:

• Test whether the OIDMON process is running. If this fails, then the probe will restart the OIDMON resource.

• Test whether the directory service is available by running $ORACLE_HOME/bin/ldapsearch. If this fails, then the probe will issue a half failure as usually the Oracle Internet Directory Monitor OIDMON process will restart the Oracle Internet Directory Process OIDLDAP. If at the next probe cycle the test fails again then another half failure is issued. If two half failures are issued by successive probes, then the probe will restart the OIDLDAP resource.

• Test whether each managed OPMN component reported by $ORACLE_HOME/dcm/bin/dcmctl getstate -v is Up. If this fails, then the probe will try to restart the OPMN component. However, in reality the OPMN process is responsible for restarting these components. If the OPMN probe tries to restart the OPMN component and the OPMN process has already tried to start the OPMN component then the duplicate restart will simply be ignored.
