Tuning Central Dispatch for Solaris

To run Central Dispatch on Solaris, you must first configure Central Dispatch.

To tune Central Dispatch for Solaris

  1. Make sure that the virtual IP address and the IP address of the Primary Scheduler are on the same Subnet.
  2. Use a dedicated user account for the Central Dispatch admin user and disable the lockout feature for this particular user.

    3. If the lockout feature is enabled, it will have an impact on the availability of the Central Dispatch site.

  3. On the Central Dispatch machine, change the Heart Beats Until Down and Agent Heart Beat Interval as follows:
    1. Bring up the Central Dispatch Manager.
    2. Navigate to Site Setup >Operations >Advanced Options.
    3. Set Heart Beats Until Down to 100.
    4. Set Agent Heart Beat Interval to 1.
    5. Navigate to Site Setup > Operations.
    6. Stop and restart the site.
  4. If are using a Sun ERI Network Interface Card (NIC), use a text editor such as vi and open /etc/system for editing.

    5. Because Central Dispatch binds to the physical NIC card, this can interfere with packet processing. Set the following variable to disable checksum on network packets processing:

    set ip:dohwcksum=0

    NOTE:  The environment variable $RESONATE_ROOT is set automatically for you when the server is started. You should not set this variable in .profile or siebenv.sh.

  5. On the Central Dispatch machine and Siebel Server machines, set the following environment variables in the /etc/rc.cdagent file (Central Dispatch startup script file). These values are the maximum permitted.

    6. HTTP_INACTIVE_CONN_TIMEOUT = 31536000

    SERVER_INACTIVE_CONN_TIMEOUT = 31536000

  6. Use the command /etc/rc.cdagent restart to restart the Central Dispatch daemons.
  7. Make sure that there are no scheduling rules registered with Central Dispatch before restarting the Siebel Servers after the site or servers were down for a refresh.

    8. NOTE:  If any open connections are observed across the site from the Dispatch Manager console, stop and restart the Central Dispatch site before starting the Siebel Servers.
