Tuning Object Manager Instances for Solaris

---

Solaris machines running more than 50 Object Managers may experience a situation where one or more of the Object Managers do not start correctly, while the rest start and function normally. The log files for the Object Managers 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 with the ndd command.

NOTE:  These settings will be lost when the machine is rebooted. Please add them to /etc/init.d to have these changes take effect even after reboot.

To change TCP values

Log in as root.
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

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

These parameters will be automatically set, when the machine is rebooted.

Restart Siebel Server as the Siebel install owner.
