Installation on UNIX

This section gives information that is specific to UNIX platforms.

Supported Platforms and Installation Packages

TIBCO Enterprise Message Service is available on the UNIX operating systems listed in Table 4. (For the latest changes, see the README file.)

Multicast and Root Access

To use multicast on UNIX, the EMS server and multicast daemon require root access when started. This can be accomplished in two ways:

1.	Start the tibemsd and tibemsmcd as the root user.

2.	Enable the setuid (set user ID) flag on the files and give root ownership to the executables.

The second method allows you to start the processes as a normal user and still provide root access on startup. However, on AIX, this prevents the server from loading the Java virtual machine (JVM) for features such as database storage or extensible security. Furthermore, this method also prevents certain Unix operating systems from saving the process's core file in the event of a crash.

If you wish to use both multicast and JVM-based features on AIX in the same EMS server, or if you encounter a crash which requires saving a core file, you must use the first method, starting the server and multicast daemon processes as the root user.

Note that once multicast initialization is complete, the EMS server and multicast daemon release root privileges.

Loading the JVM on AIX

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

In order to load the JVM on AIX, you must set LIBPATH to include the directory $JAVA_HOME/jre/bin.

To use JVM-based features with multicast, you must also start the tibemsd and tibemsmcd as the root user. This is described above, in Multicast and Root Access.

Dynamically Linked Libraries

The EMS server dynamically loads the SSL and compression shared libraries, rather than statically linking them. If the tibemsd executable is executed from the bin directory, it automatically locates these libraries. If the server is moved elsewhere, the shared library directory must be moved as well.
