Maximizing Siebel Server Performance for Solaris 9

To gain the maximum CPU performance for your Siebel Server when running on Solaris 9 or higher, 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. MPSS is available only for Solaris 9 or higher.

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
