Tuning AOM Instances for Solaris

Solaris machines running more than 50 Application Object Manager instances (multithreaded processes for AOM) may 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, 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.
