Install Apache Tomcat

As a prerequisite, the Java Runtime Environment 1.5 or later (31–bit) must be installed under z/OS.
Although any version of Tomcat above 5.5 can be used, to properly secure RMM using SAF/RACF, we recommend downloading the "T:Z - Quickstart for Tomcat" package provided by Dovetailed Technologies LLC. It can be downloaded from the following site: http://dovetail.com/downloads/tomcat/index.html.
Please follow the instructions provided by Dovetailed Technologies, LLC to download, transmit and extract Tomcat to the Tomcat installation directory within the UNIX system services on your target z/OS system
Ensure these environmental variables are set:
```
$CATALINA_HOME=tomcat_directory
```
(Replace tomcat_directory by your actual Tomcat installation directory.) You can make these settings by appropriate "export" statements within $HOME/.profile or /etc/profile. For example:
```
export CATALINA_HOME=$HOME/tomcat/apache-tomcat-x.x.x
export _BPXK_AUTOCVT=ON
```
Also verify that the $JAVA_HOME variable is set to the actual Java home directory and that the $PATH variable contains $JAVA_HOME/bin. The $LIBPATH must contain $JAVA_HOME/bin and $JAVA_HOME/bin/classic.
To make the Tomcat script files executable, tag them as follows:
```
chtag -t -c ISO8859-1 $CATALINA_HOME/bin/*.sh
```
The DFSMSrmm Web service uses a C++ DLL from the z/OS Link List. The program object is called EDGXHCLL. To make this DLL available for the DFSMSrmm Web service, install a link in the systems library path ($LIB_PATH). Go to the library path in the file system, for example: /usr/lib, and type "ln -e EDGXHCLL libEDGXHCLL.so". This step establishes an external link to the DLL in LINKLST.
