Changing the Enterprise Configuration Under Siebel Native Load Balancing
The most common configuration changes that affect load balancing performance are as follows:
- Adding or removing Siebel Servers
- Enabling or disabling Application Object Managers (AOMs)
Update your lbconfig.txt file to reflect post-configuration changes in your Siebel environment. The recommended method of updating the lbconfig.txt file is to regenerate it and reapply the SWSE logical profile as described in Enabling Siebel Native Load Balancing. The following topics describe how you can manually edit the lbconfig.txt file to reflect post-configuration changes.
Adding or Removing Siebel Servers
If you add or remove Siebel Servers that are being load-balanced, you must revise the lbconfig.txt file to add or remove the servers from the VirtualServer definition. You can revise the lbconfig.txt file as described in Enabling Siebel Native Load Balancing. Alternatively, if you have optimized the lbconfig.txt file as described in Optimizing Siebel Native Load Balancing Performance, consider editing it instead. This preserves your existing settings. After you edit the lbconfig.txt file, restart the Web server. Do this for all Web servers on which the SWSE is installed. You do not need to revise the SWSE configuration file (eapps.cfg).
Enabling or Disabling Application Object Managers (AOMs)
If you enable or disable a load-balanced Application Object Manager, you must edit the lbconfig.txt file if either of the following is true:
- You are enabling an AOM on a Siebel Server that is not included in the VirtualServer definition in lbconfig.txt. Edit the definition to add the server.
- You are disabling an AOM on a server, and the AOM is the only one being load-balanced on the server. To prevent failed connection attempts, remove the Siebel Server from the VirtualServer definition in lbconfig.txt.
After you save the file, restart the Web server. Do this for all Web servers on which the SWSE is installed. You do not need to edit the SWSE configuration file (eapps.cfg).
