Hi Pankaj,
Try the below steps,
1.Please check the /tmp folder for files :
*) GCL-SiteMinder-A.pipe
*) GCL-SiteMinder-B.pipe
*) GCL-SiteMinder.sem
Stop SiteMinder Policy Server
2. Delete files from /tmp folder
*) GCL-SiteMinder-A.pipe
*) GCL-SiteMinder-B.pipe
*) GCL-SiteMinder.sem
3. Source the environment variable . ./ca_ps_env.ksh
4.Make sure the current user who runs policy server has full rights to these pipe files or Start Siteminder using a correct user like (smuser) etc
5.Check the smps.log does not have the Failed to create the Management Command Listener error after start-up.
Regards,
Leo Joseph.
