Sun N1 System Manager 1.1 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.

ProcedureTo Increase the N1 System Manager Performance

Before You Begin

If your management server is running Red Hat, add RPCNFSDCOUNT=32 to the /etc/sysconfig/nfs file and run /etc/init.d/nfs restart as root to restart NFS.

Steps

  1. Log in to the management server as root.

  2. Update the NFS file.

    1. Change directory to /etc/sysconfig.

    2. Edit the nfs file and add the following line:

      RPCNFSDCOUNT=32

    3. Save and close the nfs file.

    4. Type /etc/init.d/nfs restart to restart NFS.

  3. Update the /etc/opt/sun/n1sm/monitoring.properties file.

    Edit the /etc/opt/sun/n1sm/monitoring.properties file and set the following tunable parameters based on the number of provisionable servers.

    Tunable Parameter (in seconds) 

    Number of Provisionable Servers 

    1–32 

    33–64 

    65–96 

    97–128 

    pollinginterval.hardwarehealth

    120 

    300 

    480 

    600 

    pollinginterval.osresources

    120 

    300 

    480 

    600 

    pollinginterval.network

    120 

    300 

    480 

    600 

    Note –

    You can also set the tunable parameters for an individual provisionable server as follows from the N1 System Manager command line prompt:


    N1-ok> set server server monitor hardwarehealth interval interval
N1-ok> set server server monitor osresources interval interval
N1-ok> set server server monitor network interval interval

    Where server is the management name of the provisionable server and interval is the monitoring interval expressed in seconds.

    For more information, type help set server at the N1 System Manager command line prompt.

  4. 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 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.

  5. 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.

  6. Start all N1 System Manager processes.

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