Solaris Cluster Unlike other Solaris Cluster data services, it is not registered to the Solaris Cluster framework. This is also the case with the shared disk groups that are used by RAC and Solaris Volume Manager, and are supported with the Cluster feature. The Cluster features enables the ability to create shared disk groups. Shared disk groups are simultaneously imported on multiple cluster nodes. The Cluster feature requires a separate license in addition to the base Veritas Volume Manager license. RAC also can be used without a volume manager with Solaris Cluster. In this configuration, redundancy is provided by the RAID support on the storage array. General setup guidelines for configuring Solaris Cluster OPS/RAC data service Refer to detailed configuration instructions in the Solaris Cluster Data Service for Oracle Real Application Clusters Guide. The following steps assume that the Solaris Cluster framework and RAC and Volume Manager are installed. Refer to the installation guides for those products for specific installation procedures. This examples assume that Veritas Volume Manager is being used. 1. Install the Solaris Cluster Support for RAC packages from the Solaris Cluster Data Services distribution cd. For Solaris 9: # cd /cdrom/suncluster_3_1/Sol_9/Packages On all cluster nodes that will be running the OPS/RAC data service install the packages: # pkgadd -d . SUNWscucm SUNWscor SUNWudlm SUNWudlmr SUNWcvmr SUNWcvm Repeat these procedures on the other cluster nodes that will run the data service. Do not reboot the nodes until the Oracle Distributed Lock Manager (UDLM) has been installed and the shared memory settings have been set up in the /etc/system file on all nodes. Verify that licenses for both the Veritas Volume Manager and Veritas Cluster Feature are installed on all nodes. 2. Install the Oracle UDLM If not already created, a database administrator group and Oracle user account must be created. On each node, an example entry in to the /etc/group file for the dba group could look like the following: dba:*:600:root,oracle One each node, create an entry for the Oracle use ID in the /etc/passwd file. For example: # useradd -u 600 -g dba -d /oracle-home oracle The group/Oracle user ID should be the same on all nodes running the RAC data service. Install the ORCLudlm package on each of the nodes to run the RAC data service. 3. Update the /etc/system file to provide appropriate shared memory resource. These values depend on available resources of the server nodes. Note: This is an example of the /etc/system file parameter settings only: Examples 67

Solaris Cluster
Unlike other Solaris Cluster data services, it is not registered to the Solaris Cluster framework.
This is also the case with the shared disk groups that are used by RAC and Solaris Volume
Manager, and are supported with the Cluster feature. The Cluster features enables the ability to
create shared disk groups. Shared disk groups are simultaneously imported on multiple cluster
nodes. The Cluster feature requires a separate license in addition to the base Veritas Volume
Manager license.
RAC also can be used without a volume manager with Solaris Cluster. In this configuration,
redundancy is provided by the RAID support on the storage array.
General setup guidelines for configuring Solaris Cluster OPS/RAC data service
Refer to detailed configuration instructions in the
Solaris Cluster Data Service for Oracle Real
Application Clusters Guide
.
The following steps assume that the Solaris Cluster framework
and RAC and Volume Manager are installed. Refer to the installation guides for those products
for specific installation procedures. This examples assume that Veritas Volume Manager is
being used.
1.
Install the Solaris Cluster Support for RAC packages from the Solaris Cluster Data
Services distribution cd.
For Solaris 9:
#
cd /cdrom/suncluster_3_1/Sol_9/Packages
On all cluster nodes that will be running the OPS/RAC data service install the packages:
#
pkgadd -d . SUNWscucm SUNWscor SUNWudlm SUNWudlmr SUNWcvmr SUNWcvm
Repeat these procedures on the other cluster nodes that will run the data service. Do not
reboot the nodes until the Oracle Distributed Lock Manager (UDLM) has been installed
and the shared memory settings have been set up in the
/etc/system
file on all nodes.
Verify that licenses for both the Veritas Volume Manager and Veritas Cluster Feature are
installed on all nodes.
2.
Install the Oracle UDLM
If not already created, a database administrator group and Oracle user account must be
created.
On each node, an example entry in to the
/etc/group
file for the dba group could look
like the following:
dba:*:600:root,oracle
One each node, create an entry for the Oracle use ID in the
/etc/passwd
file. For
example:
#
useradd -u 600 -g dba -d /oracle-home oracle
The group/Oracle user ID should be the same on all nodes running the RAC data service.
Install the ORCLudlm package on each of the nodes to run the RAC data service.
3.
Update the
/etc/system
file to provide appropriate shared memory resource. These
values depend on available resources of the server nodes.
Note:
This is an example of the
/etc/system
file parameter settings only:
