Set the LD_PRELOAD Variable for an Oracle 10G Web Server on Linux

After you install the Web Agent r12.0 SP2 on an Oracle 10G web server running on a Linux platform, you must set the LD_PRELOAD environment variable in the apachectl script.

If the LD_PRELOAD variable is not included in the apachectl script, the Oracle 10G web server may dump core upon shutdown and fail to restart.

1. Open the apachectl file.
2. Add the LD_PRELOAD entry as follows:

   LD_PRELOAD=web_agent_home/bin/libbtunicode.so

   export LD_PRELOAD

3. Run the script to start the Apache server.

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