Best practice of listener queuesize

edited Apr 15, 2014 5:03AM in Database Networking (MOSC) 2 commentsAnswered

Hi Guys.

Background:

1) Oracle 11.2.01 EE 64bit database on Solaris 10 64bit server.

2) Based on listener log we can found there are 10 - 15 successful connections per second,

3) The default number of concurrent connection requests is operating system-specific. The defaults for TCP/IP on the Solaris Operating System and Windows follow:

Solaris Operating System: 5

4) current Solaris 10 server IPC queue size 128kb

Configuring and Administering Oracle Net Listener

If you are using the IPC protocol, you can improve performance by specifying the maximum number of concurrent IPC connection requests to match your expected connection requests. In listener.ora

5) listener.ora isn't spcify queuesize.
