Additional tuning might be necessary to achieve optimal performance. Refer
to Oracle SPARC SuperCluster Tunables document 1474401.1, available at My
Oracle Support (http://support.oracle.com), for the latest information. Also, the
January 2013 QFSDP release added a "ssctuner" tool that automatically sets
tunables. Refer to the Oracle SPARC SuperCluster release notes for additional
information.
Configuring Oracle Direct NFS (dNFS)
On each Oracle SPARC SuperCluster node, configure dNFS as follows:
1.
Shut down the running instance of the Oracle Database software.
2.
Change directory to $ORACLE_HOME/rdbms/lib.
3.
Enable dNFS:<br/>
make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk dnfs_on
4.
Update the oranfstab file (located in /$ORACLE_HOME/dbs) with the server, path, and
export names specific to the configuration, where:<br/>
■
The server parameter refers to the local name of the ZFS Storage Appliance head on the
InfiniBand network.<br/>
■
The path parameters should reflect the address(es) for that head specified during
configuration.<br/>
■
The export parameters should reflect the mount points similar to the entries created in /etc/
vfstab. The entries should look similar to the following.<br/>
5.
For single IP configuration (only Oracle SPARC SuperCluster T5 without external
leaf switches):
server: aie-zba-h1-stor
path: 192.168.30.100
export: /export/test1/backup1 mount: /zba/test1/backup1
export: /export/test1/backup3 mount: /zba/test1/backup3
export: /export/test1/backup5 mount: /zba/test1/backup5
export: /export/test1/backup7 mount: /zba/test1/backup7
