Installing messaging services on multiple servers requires careful analysis and planning of system usage and resources. We strongly recommend that you use the Single Server option for most cases, and only use Multiple Servers option if you have specific needs to do so and you have a detailed deployment plan in place.
Not using Multiple Servers does not exclude you from installing messaging services
on multiple computers for load sharing and fail-over. Messaging services can be installed
on multiple computers using the Single Server option.
The information in this section is for users with special needs that require the implementation of messaging services using multiple JMS providers in a JBoss environment.
-
Insert the HxGN EAM CD, and run the installation. See Installing EAM for JBoss.
At the point during the installation when you must choose whether to install messaging services, the system displays the following dialog box.
-
Select Yes to install messaging services.
-
Click Next.
-
Select the type of messaging services to install. Select Advanced multi-server to install the messaging services for multiple servers.

Will this computer host the Databridge transactions? Select No, and then click Next.
Select Yes only if the computer on which you are installing the application server will also
host the Databridge transactions. See HxGN EAM™ Databridge System Administration.
-
For the Will this computer host a message queue? prompt choose one of these options:
Option
Description
Yes
Select if the computer on which you are installing the application server will also host a message queue.
No
Select if you do not want to host a message queue on the computer on which you are installing the application server.
For most installations, you will select Yes. However, you may want to select No for installation situations in which you are installing a large number of application
servers for which you will only want to install JMS queues on a limited number of
those application servers.
-
Click Next.
-
Enter the address of the application server(s) that are hosting the message queue(s). Use a comma (,) to separate multiple addresses, e.g., usgvl002-machine:1099, usgvl003-machine2:1099, etc. For a JBoss installation, the address is in the form of <server name>:<JBoss JNDI port number>.
