How to Configure Oracle Database Access Using Oracle ASM
Use this procedure to configure Oracle Database access using Oracle ASM. You can use
Oracle ASM on
Solaris Volume Manager.
Note -
If you use Oracle ASM in a global cluster as well as in a zone cluster
configured in that global cluster, you must ensure that, in each particular cluster,
Oracle ASM can see only those devices that are intended for its use, whether in the
global zone or in a zone cluster. If Oracle ASM can see devices that are used by
Oracle ASM in a different cluster, this can cause start problems for Oracle Clusterware or
Oracle Grid Infrastructure, because Oracle ASM sees the devices as already mounted elsewhere.
-
Configure a Support for Oracle
RAC framework resource group.
The Oracle RAC framework resource group is used by the HA for Oracle Database data
service to enable Oracle Solaris Cluster and Oracle Clusterware software to interact with each
other.
Follow procedures in Registering and Configuring the Support for Oracle RAC Framework Resource Group in Oracle Solaris Cluster Data Service for Oracle Real Application Clusters Guide
.
-
Configure the disk devices for Oracle ASM software to use.
See Using Oracle ASM in Oracle Solaris Cluster Data Service for Oracle Real Application Clusters Guide
for
information about how to configure Oracle ASM.
-
Set up the permissions for the Oracle ASM disks to be used by Oracle ASM disk
groups.
-
Run the following commands for each DID device on each Oracle Solaris Cluster node that
can master the Oracle Database resource group.
# chown oraasm:dba /dev/did/rdisk/dn
# chmod 660 /dev/did/rdisk/dn
-
Verify that the changes are effective.
# ls -lhL /dev/did/rdisk/dn
