N1 System Manager Performance Tuning

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

To Increase the N1 System Manager Performance

Steps

1. Log in to the management server as root.

2. 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.

3. 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.

4. Stop N1 System Manager.

   • On a Solaris management server, type svcadm disable n1sm

   • On a Linux management server, type /etc/init.d/n1sminit stop

   Wait for all N1 System Manager processes to stop.

5. Start N1 System Manager.

   • On a Solaris management server, type svcadm enable n1sm

   • On a Linux management server, type /etc/init.d/n1sminit start

Next Steps

If you have updated an earlier version of N1 System Manager to version 1.3, you can now use N1 System Manager 1.3.

If you have completed a first-time install of N1 System Manager 1.3, perform the following tasks:

• Log in to the N1 System Manager as described in Accessing the N1 System Manager Through the Command Line in Sun N1 System Manager 1.3 Discovery and Administration Guide.

• Define the N1 System Manager users as described in Managing Users in Sun N1 System Manager 1.3 Discovery and Administration Guide.

• Define the N1 System Manager roles as described in Managing Roles in Sun N1 System Manager 1.3 Discovery and Administration Guide.

• Run discovery to locate and identify the manageable servers as described in SP-Based Discovery in Sun N1 System Manager 1.3 Discovery and Administration Guide .

• Create the operating system distributions for the managed servers as described in Managing UNIX OS Distributions in Sun N1 System Manager 1.3 Operating System Provisioning Guide.

• Create the operating system profiles for the managed servers as described in Managing OS Profiles in Sun N1 System Manager 1.3 Operating System Provisioning Guide.

• Install the operating system distributions on the managed servers as described in Installing the UNIX OS on Managed Servers in Sun N1 System Manager 1.3 Operating System Provisioning Guide.

• Back up your N1 System Manager installation as described in Chapter 3, Backing Up and Restoring, in Sun N1 System Manager 1.3 Discovery and Administration Guide.
