Enabling Siebel Native Load Balancing


After you install and configure the Siebel Servers and install the Siebel Web Server Extension (SWSE), you start the SWSE Configuration Wizard to enable Siebel native load balancing. You generate the load balancing configuration file (lbconfig.txt) and place it in the directory where you store the SWSE logical profile, and then you configure the SWSE (apply the logical profile). For information about generating the lbconfig.txt file and applying an SWSE logical profile, see the Siebel Installation Guide for the operating system you are using. For more information about the lbconfig.txt file, see Structure of the lbconfig.txt File.

When you select Siebel native load balancing in the SWSE Configuration Wizard, the wizard then adds the Siebel native load balancing information specified in the lbconfig.txt file by modifying parameters in the SWSE configuration file (eapps.cfg) of the installed SWSE. The SWSE Configuration Wizard also copies the lbconfig.txt file from the directory that stores the SWSE logical profile to the SWSE_ROOT\admin directory, where SWSE_ROOT is the installation directory for the Siebel Web Server Extension.

NOTE:  You must apply the SWSE logical profile to all of the Web servers where the SWSE is installed for Siebel native load balancing to function correctly.

Table 10 describes the load-balancing parameters in the eapps.cfg file.
