How to Use ASMCA in Silent Mode to Configure ASM For a Stand-Alone Server

Oracle ASM Configuration Assistant (ASMCA) was introduced in Oracle ASM version 11.2. ASMCA supports installing and configuring Oracle ASM instances, disk groups, volumes, and Oracle ASM cluster file systems (Oracle ACFS). ASMCA can be used interactively, in both GUI and command-line modes, or non interactively in silent command-line mode.

This post demonstrates the use of ASMCA in silent mode, to configure ASM with ASMLIB disks, on Linux and in Oracle Restart (single instance) setup.

Before configuring ASM, perform the following tasks:

  • Prepare disks to be used for ASM and present them to the OS.
  • Setup ASMLIB and create ASM disks.
  • Install Oracle Grid Infrastructure - software only.
  • Configure Grid Infrastructure install for a stand-alone server by running

Configure ASM with a single disk group and use all ASMLIB disks. All commands are to be run from the Grid Infrastructure home, as the Grid Infrastructure owner.

1. Check for available ASM disks:

$ oracleasm listdisks

2. Configure ASM:

$ asmca -silent -configureASM -sysAsmPassword sysPassw0rd -asmsnmpPassword asmsnmpPassw0rd -diskString 'ORCL:*' -diskGroupName DATA -disk 'ORCL:*' -redundancy EXTERNAL

3. On successful run, the above command should have returned:

ASM created and started successfully.
DiskGroup DATA created successfully.

And it should have performed the following:

  • Start the cluster services daemon (process ocssd.bin).
  • Start three agents (processes cssdagent, oraagent.bin and orarootagent.bin).
  • Start the disk monitor (process diskmon.bin).
  • Start the ASM instance, with instance name +ASM.
  • Create the external redundancy disk group named DATA.
  • Create ASM’s own spfile in disk group DATA.
