Tuning Siebel Application Object Manager Instances for Oracle Solaris

This topic is part of Tuning Siebel Business Applications for Oracle Solaris.

Oracle Solaris computers running more than 50 Siebel 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, change the tcp_conn_req_max_q and tcp_conn_req_max_q0 default values, then 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.
