3.7.0 HP StorageWorks HP Scalable NAS File Serving Software provisioning guide for Oracle HP Scalable NAS (AG513-96013, October 2009)

For example, you may determine that the Oracle owner is oracle and user oracle
will have uid 500. Groups dba and oinstall will have gids 1000 and 1001
respectively. The NAS administrator then runs the following commands on each server
in the cluster:
groupadd g 1000 dba
groupadd g 1001 oinstall
useradd u 500 g oinstall G dba d /home/oracle oracle
If the exports for this Oracle owner are from /u03/app/oracle (for
$ORACLE_HOME) and /u04 for oradata, then on any of the NFS servers run the
following commands to set the proper permissions:
mkdir p /u03/app/oracle
chown R oracle:oinstall /u03/app/oracle
chown R oracle:oinstall /u04
This step is completely optional, but highly recommended.
Hosting Virtual NFS Services for high performance
HP Scalable NAS includes a script called SizingActions that configures certain
operating system parameters to improve system performance, particularly in a file
serving environment. The changes improve network throughput and make better use
system memory. On HP X5500 Storage Gateway for Linux, HP Scalable NAS
Clustered Gateway, and HP 4400 Scalable NAS File Services systems, additional
changes are made to tune the operating system for the hardware provided with those
systems.
The SizingActions script is run when HP Scalable NAS starts up. The script does
not determine whether the system parameters it adjusts have been modified from
their default values by a user on the system. This can be an issue if, for example, you
are running an application that requires system parameters such as vmem_max or
mmem_max to be modified, typically in the /etc/sysctl.conf file.
If you do adjust system parameters to support external applications such as Oracle,
you should disable the SizingActions script as described below. Because disabling
the script will typically result in a degradation to network file serving performance,
HP recommends that you do this only if you must adjust parameters for best
performance for your application. HP does not recommend manually editing the
SizingActions script, as it may be replaced during an upgrade or hotfix and
those changes will not be preserved during the upgrade process.
