ASMInst agent functions
The ASMInst agent monitors the processes of ASM instance.
Table: ASMInst agent operations lists the ASMInst agent operations.
Table: ASMInst agent operations
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:
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. |
