Sun N1 System Manager 1.2 Installation and Configuration Guide

N1 System Manager Performance Tuning

Tune the N1 System Manager for maximum performance based on the number of provisionable servers you plan to manage. The following procedure should be done before you run discovery.

To Increase the N1 System Manager Performance

Steps

Linux only: Update the NFS file.
1. Edit the file /etc/sysconfig/nfs file and add the following line:
```
RPCNFSDCOUNT=32
```
2. Save and close the file.
3. Type /etc/init.d/nfs restart to restart NFS.

Update the package.cache.xml file.

Edit the /opt/sun/n1gc/lib/package.cache.xml file and locate the line containing attribute name="FirmwareInfos". Update the line to read as follows:
```
<attribute name="FirmwareInfos" refresh-interval="-1" delay="none" persistent="true"> />
```
This instruction ensures that the first invocation of the show server command after a restart of the N1 System Manager does not take a long time to complete.

Stop all N1 System Manager processes.

Type /etc/init.d/n1sminit stop to stop the N1 System Manager.

Wait for all N1 System Manager processes to stop.

Start all N1 System Manager processes.

Type /etc/init.d/n1sminit start to start the N1 System Manager.
