Applies to:

Oracle Server - Enterprise Edition - Version: 11.2.0.1 to 11.2.0.2 - Release: 11.2 to 11.2
Information in this document applies to any platform.

Goal

In order to provide the maximum ASM high availability on a cluster, it is always better and recommended to setup the powerful Oracle RAC architecture (this is the best option).

But if you decided to setup ASM on an active/passive cluster you can follow the next steps to setup ASM:

Solution

A) Setup the Active/Passive Cluster using third party clusterware (which provides the failover) such as Veritas, SFRAC, IBMPowerHA, or HP Serviceguard.

Note: Please check with your cluster vendor for details about the clusterware configuration.

B) Then in order to setup an ASM 11gR2 (Grid Infrastructure) Active/Passive Cluster (non-RAC), please follow the next steps:

On Node #1

1) You need to install the 11.2 GI Infrastructure Standalone “Software Only” first.

2) Then configure the CSS & OHAS services as root user:

# $/crs/install/roothas.pl -deconfig -force

# $/crs/install/roothas.pl

3) Perform. the next steps as oracle user:

$> /bin/crsctl modify resource "ora.cssd" -attr "AUTO_START=1"

$>/bin/crsctl modify resource "ora.diskmon" -attr "AUTO_START=1"

4) Check the CSS & OHAS state as oracle OS user:

$> crsctl check has

$> crsctl check css

5) Create the default listener (LISTENER) thru the NETCA using port 1521.

6) Create the init+ASM.ora file on the $/dbs directory with the next parameters:

asm_diskgroups=

asm_diskstring= 'ORCL:*' -- or '/dev/oracleasm/disks/*'

instance_type='asm'

large_pool_size=12M

7) Add the ASM instance as oracle user or the Grid Infrastructure installation owner and execute:

$> $/bin/srvctl add asm

8) Enable Auto Start as follow:

$> $/bin/crsctl modify resource "ora.asm" -attr "AUTO_START=1"

9) Make sure the disks are discovered by kfod:

Example:

kfod asm_diskstring='ORCL:*' disks=all

kfod asm_diskstring='/dev/oracleasm/disks/*' disks=all

10) If so, then startup the ASM instance as follow:

$> export ORACLE_SID=+ASM

$> sqlplus “/as sysasm”

SQL> startup pfile=init+ASM.ora --#init file from point #6

SQL> show parameter asm

11) Create a new diskgroup:

SQL> create diskgroup DATA external redundancy disk '';

12) Validate the diskgroup was mounted:

SQL> select name, state from v$asm_diskgroup;

13) Then shutdown the ASM instance to setup node #2.

On Node #2

14) You need to install the 11.2 GI Infrastructure Standalone “Software Only” first.

15) Then configure the CSS & OHAS services as root user:

# $/crs/install/roothas.pl -deconfig -force

# $/crs/install/roothas.pl

16) Perform. the next steps as oracle user:

$> /bin/crsctl modify resource "ora.cssd" -attr "AUTO_START=1"

$>/bin/crsctl modify resource "ora.diskmon" -attr "AUTO_START=1"

17) Check the CSS & OHAS state as oracle OS user:

$> crsctl check has

$> crsctl check css

18) Create the default listener (LISTENER) thru the NETCA using port 1521.

19) Create the init+ASM.ora file on the $/dbs directory with the next parameters:

asm_diskgroups=

asm_diskstring= 'ORCL:*' -- or '/dev/oracleasm/disks/*'

instance_type='asm'

large_pool_size=12M

20) Add the ASM instance as oracle user or the Grid Infrastructure installation owner and execute:

$> $/bin/srvctl add asm

21) Enable Auto Start as follow:

$> $/bin/crsctl modify resource "ora.asm" -attr "AUTO_START=1"

22) Make sure the disks are discovered by kfod:

Example:

kfod asm_diskstring='ORCL:*' disks=all

kfod asm_diskstring='/dev/oracleasm/disks/*' disks=all

23) If so, then startup the ASM instance as follow:

$> export ORACLE_SID=+ASM

$> sqlplus “/as sysasm”

SQL> startup pfile=init+ASM.ora --#init file from point #19

SQL> show parameter asm

 

24) Validate the diskgroup was mounted:

SQL> select name, state from v$asm_diskgroup;

Note: You do not need to create new diskgroup(s), since they were already created from node #1 on a shared storage between the 2 nodes.
