You must install the Oracle UDLM software on the local disk of each node.
Before you install the Oracle UDLM software, ensure that you have created entries for the database administrator group and the Oracle user ID. See How to Prepare the Sun Cluster Nodes for details.
Become superuser on a cluster node.
Install the Oracle UDLM software.
See the appropriate Oracle Parallel Server/Real Application Clusters installation documentation for instructions.
Ensure that you did not receive any error messages when you installed the Oracle UDLM packages. If an error occurred during package installation, correct the problem before you install the Oracle UDLM software.
Update the /etc/system file with the shared memory configuration information.
You must configure these parameters based on the resources that are available in the cluster. Decide on the appropriate values, but ensure that the Oracle UDLM can create a shared memory segment according to its configuration requirements.
The following example shows entries to configure in the /etc/system file.
*SHARED MEMORY/ORACLE set shmsys:shminfo_shmmax=268435456 set semsys:seminfo_semmap=1024 set semsys:seminfo_semmni=2048 set semsys:seminfo_semmns=2048 set semsys:seminfo_semmsl=2048 set semsys:seminfo_semmnu=2048 set semsys:seminfo_semume=200 set shmsys:shminfo_shmmin=200 set shmsys:shminfo_shmmni=200 set shmsys:shminfo_shmseg=200 forceload: sys/shmsys forceload: sys/semsys forceload: sys/msgsys |
Shut down and reboot all of the nodes.
Before you reboot, you must ensure that you have correctly installed and configured the Oracle UDLM software. Also verify that you have correctly installed your volume manager packages. If you use VxVM, check that you have installed the software and that the license for the VxVM cluster feature is valid. Otherwise, a panic will occur.
After you have installed the Oracle UDLM software on each cluster node, go to How to Install the Oracle RDBMS Software and Create Your Oracle Database to install the Oracle RDBMS software.
