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
- Using an editor such as
vi, open the
/etc/system file for editing.
- Add the following line to the file:
- Reboot the server.
- Create a configuration file (mpss.cfg) for MPSS configuration with the following line in the file:
where 4M is the heap size (4 MB) and 64K is the stack size (64 KB).
- Add the following lines to the
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.
