lbplugin (libpassthrough.so) can not be used when server is running in 64-bit mode (ID 6480952)

Description

When running Application Server Enterprise Edition 8.2 with Web Server 7.0 in 64–bit mode, attempts to run a 64–bit version of the load balancer plugin fail with the following error:

failure: CORE2253: Error running Init function load-modules: dlopen 
of /export/home/mareks/opt/webserver7/plugins/lbplugin/bin/libpassthrough.so 
failed (ld.so.1: webservd: fatal: /export/home/mareks/opt/webserver7/plugins/
lbplugin/bin/libpassthrough.so: wrong ELF class: ELFCLASS32)
failure: server initialization failed

The problem is that there is no 64–bit load balancer plugin for Application Server Enterprise Edition 8.2, and the 64–bit Web Server requires 64–bit plugins.

You can determine whether Web Server is running in 64–bit or 32–bit mode by using the following command:

wadm get-config-prop --user=admin --config=xxx --password-file=xxx platform

Solution

No 64–bit load balancer is planned for Application Server Enterprise Edition 8.2. To work around the problem, either use the Web Server 7.0 reverse proxy feature, or configure Web Server 7.0 to run in 32–bit mode. Refer to the Web Server documentation for instructions.
