9 Installing Cluster Ready Services on Windows-Based Systems

Installing Cluster Ready Services on Windows-Based Systems

Perform the following procedures to complete phase one of the installation of the Oracle Database 10g with Real Application Clusters (RAC).

Using the Oracle Universal Installer to Install Cluster Ready Services on Windows

Perform the following procedures to install CRS on Windows-based systems:

1. Run the setup.exe command on the Oracle Cluster Ready Services Release 1 (10.1.0.2) CD-ROM. This will open the Oracle Universal Installer (OUI) Welcome page.

2. After you click Next on the Welcome page, the Specify File Locations page will allow you to accept the displayed path name for the CRS products or select a different one. You may also accept default directory and path name for the location of your CRS home or browse for an alternate directory and destination. You must select a destination that exists on each cluster node that is part of this installation. Click Next to confirm your choices and proceed to the Language Selection page.

   
   

   Note: Your CRS home cannot be installed in an Oracle Cluster File System.

3. Select the language or languages for your CRS installation on the Language Selection page, then click Next for the Cluster Configuration page.

4. The Cluster Configuration page contains predefined node information if the OUI detects that your system has the Oracle9i Release 2 clusterware. Otherwise, the OUI displays the Cluster Configuration page without predefined node information.

   Provide your own cluster name if you do not wish to use the name provided by the OUI. Note that the selected cluster name must be globally unique throughout the enterprise and its allowable character set is the same as that for hostnames, which excludes special characters such as (, ), !, @, #, %, ^, &, and *.

   Enter a public and a private node name for each node. Neither the public nor the private name should have a domain qualifier. When you enter the public node name, use the primary host name of each node, that is, the name displayed by the hostname command. The private node refers to an address that is only accessible by the other nodes in this cluster, and which Oracle uses for Cache Fusion processing. You may enter either a private node name or a private IP address for each node.

   Click Next after you have entered the cluster configuration information. This saves your entries and opens the Private Network Enforcement page.

5. In the Private Interconnect Enforcement page the OUI displays a list of cluster-wide interfaces. Use the drop-down menus on this page to classify each interface as Public, Private, or Do Not Use. The default setting for each interface is Do Not Use. You must classify at least one interconnect as Public and one as Private.

6. On the Select Disk Formatting Options page, you indicate what OCFS you want the OUI to format for you. The formatting options are as follows:

   • Format two logical drives for data and software storage. In this case, the OUI creates two cluster file systems, one for the database files and one for the Oracle home. The OCR and voting disk are created in the datafile directory.

   • Format one logical drive for software storage. In this case, the OUI creates one cluster file system for the Oracle home and requires two additional partitions, one for the OCR and one for the voting disk. If you select this option, then you must have configured the partitions as described in "Creating Partitions and Logical Drives" before proceeding with the installation. These partitions will be stamped with "ocrcfg" for the OCR and "votedsk" for the voting disk.

   • Format one logical drive for data file storage. In this case, the OUI creates one cluster file system for the database files which is also used to store the OCR and voting disk.

   • Do not format any logical drives. In this case, the OUI requires two partitions, one for the OCR and one for the voting disk. If you select this option, then you must have configured the partitions as described in "Creating Partitions and Logical Drives" before proceeding with the installation. These partitions will be stamped with "ocrcfg" for the OCR and "votedsk" for the voting disk.

   Click Next after making your selection on the Select Disk Formatting Options page. The next page that the OUI displays depends on your selection on the Select Disk Formatting Options page, as described in the following step.

   
   

   Note: If you are installing on a cluster with an existing cluster file system from an earlier release of Oracle, then the OCR and voting disk will be stored in that file system. In this case, you do not require new partitions for the OCR and voting disk, even if you do not format a logical drive for data file storage.

7. If you selected the "Format two logical drives for data and software storage" option on the Select Disk Formatting Options page, then you must complete the Select Software Storage Drive page and the Select Data Storage Drive page as described in Steps a and b respectively.

   If you selected the "Format one logical drive for software storage" option on the Select Disk Formatting Options page, then you must complete the Select Software Storage Drive page, the Disk Configuration - Oracle Cluster Registry (OCR) page, and the Disk Configuration - Voting Disk page as described in Steps a, c, and d respectively.

   If you selected the "Format one logical drive for data file storage" option on the Select Disk Formatting Options page, then you must complete the Select Data Storage Drive page as described in Step b.

   If you selected the "Do not format any logical drives" option on the Select Disk Formatting Options page, then you must complete the Disk Configuration - Oracle Cluster Registry (OCR) page and the Disk Configuration - Voting Disk page as described in Steps c and d respectively.

   1. On the Select Software Storage Drive page, choose a shared drive to see a list of available partitions on that drive. Choose a partition with sufficient space to hold your Oracle home and select the partition's disk number and partition number from the list. Click Next to proceed.

   2. On the Select Data Storage Drive page, choose a shared drive to see a list of available partitions on that drive. Choose a partition with sufficient space to hold your database files and select the partition's disk number and partition number from the list. Click Next to proceed.

   3. On the Disk Configuration - Oracle Cluster Registry (OCR) page, choose a partition with sufficient space to hold your OCR and select the partition's disk number and partition number from the list. Click Next to proceed.

   4. On the Disk Configuration - Voting Disk page, choose a partition with sufficient space to hold your voting disk and select the partition's disk number and partition number from the list. Click Next to proceed.

   
   

   Note: The OUI pages described in this step display logical drives from which you must make your selections. To be valid for selection, a logical drive must be located on a disk without a primary partition.

8. After you click Next, the OUI checks whether the remote inventories are set. If they are not set, then the OUI sets up the remote inventories by setting registry keys. The OUI also verifies the permissions to enable writing to the inventory directories on the remote nodes. After completing these actions, the OUI displays a Summary page that shows the cluster node information along with the space requirements and availability. Verify the installation that the OUI is about to perform and click Finish.

9. When you click Finish, the OUI installs the OCFS and CRS software on the local node and validates the installation again. The OUI will also create any required OCFS file systems. After validating the installation, the OUI completes the CRS software installation and configuration on the remote nodes.

At this point, you have completed phase one, the CRS installation and are ready to install the Oracle Database 10g with RAC as described in Chapter 10, " Installing Oracle Database 10g with Real Application Clusters".

Formatting Drives to Use Oracle Cluster File System after Installing Oracle Database 10g with RAC

If you install the Oracle Database 10g with RAC, and later want to install OCFS, then execute the ocfsformat.exe command from the crs_home\cfs directory using the following syntax:

crs_home\cfs\ocfsformat.exe /l drive_letter /c clustersize [/v volume_label] [/f]

where:

• drive_letter is the drive on which you want to format the OCFS

• clustersize is the size of the partition in kilobytes

• volume_label is an optional volume label
