Maximizing Siebel Server Performance for Solaris

To gain the maximum CPU performance for your Siebel Server when running on Solaris, use the Multiple Page Size Support (MPSS) with optimal configuration of 4 MB heap size and 64 KB stack size, as outlined in the following procedure.

To set up MPSS with optimal configuration of 4 MB heap size and 64 KB stack size

1. Using an editor such as vi, open the /etc/system file for editing.
2. Add the following line to the file:

   set kernel_cage_enable=1

3. Reboot the server.
4. Create a configuration file (mpss.cfg) for MPSS configuration with the following line in the file:

   sieb*:4M:64K

   where 4M is the heap size (4 MB) and 64K is the stack size (64 KB).

5. Add the following lines to the $Siebel_Root/siebsrvr/bin/siebmtshw file:

   LD_PRELOAD=/usr/lib/mpss.so.1

   MPSSCFGFILE=Full path, including the file name, to the MPSS configuration file created in Step 4.

   MPSSERRFILE=Full path, including the file name, to the MPSS error log you want to be generated in case of any errors.

   export LD_PRELOAD MPSSCFGFILE MPSSERRFILE
