Tuning Siebel Application Object Manager Instances for Oracle Solaris

This topic is part of Tuning Siebel CRM for Oracle Solaris.

Oracle Solaris computers running more than 50 Application Object Manager instances (multithreaded processes for Siebel Application Object Manager) might experience a situation where one or more of the processes do not start correctly, while the rest start and function normally. The log files for the processes that do not start will indicate that they have not started correctly. If you experience these symptoms, then change the tcp_conn_req_max_q and tcp_conn_req_max_q0 default values, using the ndd command.

To change TCP values

  1. Log in as root.

  2. Issue the ndd command:

    Note: The responses are noted in bold.
    ndd /dev/tcp
    name to get/set ? tcp_conn_req_max_q
    value ? 1024
    name to get/set ? tcp_conn_req_max_q0
    value? 4096
    
  3. Add the following lines to the /etc/system file, using any text editor such as vi:

    set tcp:tcp_conn_req_max_q = 1024
    set tcp:tcp_conn_req_max_q0 = 4096
    
  4. Save your changes and exit the editor.
