Sun Cluster 3.1 Data Service 5/03 Release Notes

Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters

This section discusses errors and omissions from Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters.

Pre-Installation Considerations

Pre-installation considerations for using Oracle Parallel Server/Real Application Clusters with the cluster file system are missing from “Overview” in Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters.

Oracle Parallel Server/Real Application Clusters is a scalable application that can run on more than one node concurrently. You can store all of the files that are associated with this application on the cluster file system, namely:

For optimum I/O performance during the writing of redo logs, ensure that the following items are located on the same node:

For other pre-installation considerations that apply to Sun Cluster Support for Oracle Parallel Server/Real Application Clusters, see “Overview” in Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters.

How to Use the Cluster File System

Information on how to use the cluster file system with Oracle Parallel Server/Real Application Clusters is missing from “Installing Volume Management Software With Sun Cluster Support for Oracle Parallel Server/Real Application Clusters” in Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters.

To use the cluster file system with Oracle Parallel Server/Real Application Clusters, create and mount the cluster file system as explained in “Configuring the Cluster” in Sun Cluster 3.1 5/03 Software Installation Guide. When you add an entry to the /etc/vfstab file for the mount point, set UNIX file system (UFS) file system specific options for various types of Oracle files as shown in the following table.

Table 1–3 UFS File System Specific Options for Oracle Files

How to Install Sun Cluster Support for Oracle Parallel Server/Real Application Clusters Packages With the Cluster File System

Information on how to install Sun Cluster Support for Oracle Parallel Server/Real Application Clusters packages with the cluster file system is missing from “Installing Volume Management Software With Sun Cluster Support for Oracle Parallel Server/Real Application Clusters” in Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters.

To complete this procedure, you need the Sun Cluster CD-ROM. Perform this procedure on all of the cluster nodes that can run Sun Cluster Support for Oracle Parallel Server/Real Application Clusters.

Note –

Due to the preparation that is required prior to installation, the scinstall(1M) utility does not support automatic installation of the data service packages.

  1. Load the Sun Cluster CD-ROM into the CD-ROM drive.

  2. Become superuser.

  3. Change the current working directory to the directory that contains the packages for the version of the Solaris operating environment that you are using.

    • If you are using Solaris 8, run the following command:


      # cd /cdrom/suncluster_3_1/SunCluster_3.1/Sol_8/Packages

    • If you are using Solaris 9, run the following command:


      # cd /cdrom/suncluster_3_1/SunCluster_3.1/Sol_9/Packages

  4. On each node of the cluster, transfer the contents of the required software packages from the CD-ROM to the node.


    # pkgadd -d . SUNWscucm SUNWudlm SUNWudlmr
Caution – Caution –

Before you reboot the nodes, you must ensure that you have correctly installed and configured the Oracle UDLM software. For more information, see “Installing the Oracle Software” in Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters.

Where to Go From Here

Go to “Installing the Oracle Software” in Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters to install the Oracle UDLM and Oracle RDBMS software.

Using the Sun Cluster LogicalHostname Resource With Oracle Parallel Server/Real Application Clusters

Information on using the Sun Cluster LogicalHostname resource with Oracle Parallel Server/Real Application Clusters is missing from Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters .

If a cluster node that is running an instance of Oracle Parallel Server/Real Application Clusters fails, an operation that a client application attempted might be required to time out before the operation is attempted again on another instance. If the TCP/IP network timeout is high, the client application might take a long time to detect the failure. Typically client applications take between three and nine minutes to detect such failures.

In such situations, client applications may use the Sun Cluster LogicalHostname resource for connecting to an Oracle Parallel Server/Real Application Clusters database that is running on Sun Cluster. You can configure the LogicalHostname resource in a separate resource group that is mastered on the nodes on which Oracle Parallel Server/Real Application Clusters is running. If a node fails, the LogicalHostname resource fails over to another surviving node on which Oracle Parallel Server/Real Application Clusters is running. The failover of the LogicalHostname resource enables new connections to be directed to the other instance of Oracle Parallel Server/Real Application Clusters.

Caution – Caution –

Before using the LogicalHostname resource for this purpose, consider the effect on existing user connections of failover or failback of the LogicalHostname resource.
