Installing the Oracle UDLM involves the following tasks:
Preparing the nodes
Installing the Oracle UDLM software
For the Oracle UDLM software to run correctly, sufficient shared memory must be available on all of the cluster nodes. See the Oracle Parallel Server/Real Application Clusters CD-ROM for all of the installation instructions. To prepare the Sun Cluster nodes, check that you have completed the following tasks.
You have correctly set up the Oracle user account and database administration group.
You have configured the system to support the shared memory requirements of the Oracle UDLM.
Perform the following steps as superuser on each cluster node.
This group normally is named dba. Verify that root and oracle are members of the dba group, and add entries as necessary for other database administrator (DBA) users. Verify that the group IDs are the same on all of the nodes that run Sun Cluster Support for Oracle Parallel Server/Real Application Clusters. For example, add the following entry to the /etc/group file.
You can make the name service entries in a network name service, such as the Network Information Service (NIS) or NIS+, so that the information is available to the data service clients. You can also make entries in the local /etc files to eliminate dependency on the network name service.
This Oracle user ID is normally oracle. For example, add the following entry to the /etc/passwd file.
# useradd -u 120 -g dba -d /oracle-home oracle
Ensure that the user IDs are the same on all of the nodes that run Sun Cluster Support for Oracle Parallel Server/Real Application Clusters.
After you set up the cluster environment for Oracle Parallel Server/Real Application Clusters, go to How to Install the Oracle UDLM Software to install the Oracle UDLM software on each cluster node.
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.
You must configure these parameters on the basis of the resources that are available in the cluster. Decide the appropriate values, but ensure that the Oracle UDLM can create a shared memory segment that conforms 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
Shut down and reboot each node on which the Oracle UDLM software is installed.
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.
For detailed instructions, see “Shutting Down and Booting a Single Cluster Node” in Sun Cluster System Administration Guide for Solaris OS.
After you have installed the Oracle UDLM software on each cluster node, the next step depends on your storage management scheme.
If you are using VxVM without the cluster file system, go to Creating a VxVM Shared-Disk Group for the Oracle Parallel Server/Real Application Clusters Database to create a shared-disk group for the Oracle Parallel Server/Real Application Clusters database.
Otherwise, go to Registering and Configuring Sun Cluster Support for Oracle Parallel Server/Real Application Clusters to register and configure Sun Cluster Support for Oracle Parallel Server/Real Application Clusters.
