How to change the database port for IDM Role Mapping Administrator

By default it is not possible to set the database port during the installation of IDM Role Mapping Administrator.  This means if
someone wanted to use a single machine for both a staging sandbox as well as a production server, they would not be able to.

Currently when you start the 2nd instance of the IDM Role Mapping Administrator application you get
the following error at startup:

[Server@bf2d5e]: [Thread[HSQLDB Server @bf2d5e,5,main]]:
run()/openServerSocket():
java.net.BindException: Address already in use

To customize the embedded DB listening port to avoid conflicting use the following steps:

1. Go to Role Mapping Administrator's installation folder, find
tomcat/bin/catalina.sh and open it in an editor.
2. Find the section of "#Start the HSQL Database" where you can see the
following command which invokes the DB server:
"$_RUNJAVA" -cp  "$CATALINA_BASE/lib/hsqldb.jar" org.hsqldb.Server -database.0
file:$CATALINA_BASE/db/mydb -dbname.0 idmrmap
3. Insert the following option to the command right before "-database.0":
-port <customized_port_number>
4. Save and close the file.
5. find tomcat/webapps/IDMRMAP/WEB-INF/classes/hibernate.cfg.xml and open it in
an editor.
6. find the following line:
<property name="connection.url">
7. modify the value of the property from:
jdbc:hsqldb:hsql://localhost/idmrmap
to
jdbc:hsqldb:hsql://localhost:<customized_port_number>/idmrmap
8. Save and close the file
