Uneven Load Balancing of Forms when using using OHS Weblogic Plug-In (Doc ID 2437483.1)

Last updated on MAY 31, 2023

Applies to:

Oracle Forms - Version and later
Information in this document applies to any platform.


The Oracle HTTP Server (OHS) Weblogic (WLS) plug-in is configured to direct Forms requests to two different Weblogic servers.  For example, the mod_wl_ohs.conf or forms.conf file is configured as follows:

<Location /forms>
    SetHandler weblogic-handler
    WebLogicCluster server1:<PORT1>,server2:<PORT2>
    DynamicServerList OFF

When this is configured, by default the WLS plug-in will load balance using a simple round-robin algorithm between all available servers.

However, it is observed that load balancing between the two servers is uneven with 60% or more connections being serviced on one server.
