Agent operation

Description

Online

Starts the Oracle ASM instance by using the following SQL command:

startup nomount

The Online operation starts the ASM instance without mounting any disk groups.

Offline

Stops the Oracle ASM instance by using the following SQL command:

shutdown immediate

Monitor

Verifies the status of the ASM instance.

The ASMInst agent can monitor the ASM instance in two ways; process check monitoring and health check monitoring. The default is process check monitoring.

In the process check monitoring mode, the agent scans the process table for the asm_pmon, asm_smon, asm_lgwr, asm_rbal, and asm_dbw0 processes to verify that the ASM instance is running.

The agent also checks if the ocssd.bin process is running. The agent returns offline for the following conditions:

  • The process is not running.

  • The process is restarted.

Note:

Make sure that the OCSSD process is running. The ASMInst agent only monitors the OCSSD process. The agent does not start or stop the process.

Clean

Forcibly stops the Oracle ASM instance by using the following SQL command:

shutdown abort

If the process does not respond to the shutdown command, the agent kills the process using the SIGTERM or SIGKILL commands.
