## Root Access and Administrative Privileges

If TIBCO Enterprise Message Service is installed and `tibemsd` is started as root, it drops root permissions after the server starts.

This protects the EMS server from security exploits. Once the server has dropped root privileges, it cannot write to the files created during the installation. As a result, it is not able to create configuration and log files. To avoid this conflict, create the necessary directories and assign the appropriate privileges to the regular user ID with which the EMS server is started.

## Load the JVM on AIX

The JVM is required to run certain features, such as extensible security and database storage.

In order to load the IBM JVM on AIX, you must set `module_path` in the tibemsd.conf to point to the directories containing the `libjvm.so` and its dependent libraries. These libraries are part of your JRE installation.
