Share configuration is the process of setting up and running NFS mount points for client access. Two projects should be created for the Oracle SPARC SuperCluster configuration: one project per pool. A project is an entity that provides a higher level management interface point for a collection of shares. To optimize share management, update the default mount point for shares contained in the project to reference the database name, such as /export/dbname. For a performance-optimized system, create four shares for each project in each pool, for a total of eight shares (four for each head). To configure a project, perform the following:
1. Log on to the BUI of Head 1 and navigate to Shares > Projects.
2. Click the plus icon next to Projects, enter a meaningful name for the project, and click Apply. Since a similar project will be created on the other head, uniquely name the project for Head 1, such as H1-mydb.
3. Click the pencil icon next to the new project name to edit the project.
4. Click General and complete the properties as follows:
Change the Mountpoint to include the database name (for example, /export/H1-mydb).
Change Synchronous write bias from Latency to Throughput and click Apply.
5. Click Protocols and add an NFS exception as follows:
Click the plus icon next to NFS Exceptions.
Change Type to Network.
Enter the subnet and netmask (for example, /24) of the InfiniBand network.
Change Access Mode to Read/Write.
Verify that Charset is set to default.
Check the Root Access box and click Apply.
6. Next to General, click Shares.
7. Create four filesystems for Head 1 and uniquely name them so they will be different from the names for Head 2. To interleave the backup streams to distribute the data across the two heads and, thereby, provide better performance, use odd-numbered names for Head 1, such as backup1, backup3, backup5, and backup7; and use even-numbered names for Head 2, such as backup2, backup4, backup6, and backup8. To create the filesystems, click the plus icon next to Filesystems, enter the name of the filesystem (backup1), and click Apply. Repeat this step to create the remaining three filesystems (backup3, backup5, and backup7).
8. Repeat steps 1 through 7 for Head 2. Remember to use a unique project name (for example, H2-mydb), and specify even-numbered backup IDs (backup2, backup4, backup6, and backup8) for the filesystem names.
