Set the LD_PRELOAD Variable for Apache Web Server on SUSE Linux 98

After you install the Web Agent r12.1 on an Apache web server running on SUSE 9, you must set the LD_PRELOAD environment variable as follows:

LD_PRELOAD=web_agent_home/bin/libbtunicode.so

Without this setting, two problems may occur:

• The Apache web server may dump core upon shutdown.
• When a SAML Affiliate Agent is running on an Apache Web Server, a load change may spawn multiple processes that eventually consume 100% of the CPU cycles.

Note: Setting this environment variable causes any application executed from that environment to bind with libbtunicode.so. Therefore, only set this variable when starting or stopping a web server that loads the SOA Security Manager Web Agent.
