The JAMS OpenVMS Connection Server comes in the SetupJAMSOpenVMS package. This package includes the JAMS Client, JAMS Agent, and JAMS OpenVMS Connection Server.

Note the Client and Agent are exactly the same as paired in the Windows Setup kits. |
Where to Install the OpenVMS Connection Server
The JAMS OpenVMS Connection Server is a Windows service that can be shared by many JAMSWin Clients simultaneously when installed on a server.
As an alternative, you can choose to install the JAMS OpenVMS Connection Server on individual workstations to be used by exclusively by one JAMSWin Client. This is perhaps the more flexible option, but can require more resources on the OpenVMS server. You can, of course, use a mixture of these two approaches.
Installing the Connection Server
- Log on to Windows using an account with administrator privileges.
- Run the SetupJAMSOpenVMS executable to start the JAMS setup wizard.
- On the Welcome page, verify this is the proper edition and version and then select the Next button.
- On the License Terms page, review the terms and conditions. If acceptable, select I accept the terms of the License Agreement and click Next.
- On the Feature Selection page, choose the features that you want to install or upgrade, and choose Next.
- On the Select Target Directory page, select a target directory or accept the default, and click Next. If this is an upgrade, the target directory cannot be modified.
Configuring the JAMS OpenVMS Connection Server
When installing the JAMS OpenVMS Connection Server for the first time, you will need to edit the User.config file. The configuration settings are described in the table.
| Setting | Description |
| ServerName | Required: Enter the name and IP address of the OpenVMS server. |
| ServerPort | Include the TCP/IP port for the OpenVMS server. The default is 773. The following table describes the specific TCP/IP ports used by JAMS |
| SMTPServer | Include the name of the SMTP server. This setting is used to notify you via email if the service fails. Note: the best way to configure you SMTP server is from your machine.config file to apply the settings to all applications on the PC. |
| ErrorEmail | Enter the email address to receive any error reports. |
| MinimumConnections | Include the minimum number of connections to the OpenVMS server. The default is 1. |
| MaximumConnections | Include the maximum number of connections to the OpenVMS server. The default is 4. If a client has to wait too long for an OpenVMS connection, a new connection will be created until the maximum number is reached. |
|
Note: Even though the OpenVMS Connection server runs on the JAMS Server, the JAMSWin Client never connects directly with the OpenVMS machine. |
JAMS TCP/IP Ports
JAMS uses the following TCP/IP ports:
| Port | JAMS Executable | Description |
| 77 | JAMSAgent.exe | The JAMS Agent listens on port 77 for Job requests coming from other JAMS machines. |
| 773 | JAMSServer.exe | The JAMS Server listens on port 773 for connection requests from JAMSWin Clients. |
| 2773 | JAMSScheduler.exe | The JAMS Scheduler listens on port 2773 for connections from the JAMS Server and JAMS Debugger. This process is usually confined to the local machine. |
| 3773 | JAMSExecutor.exe | The JAMS Executor uses port 3773 for connections from the JAMS Scheduler and JAMS Debugger. This process is usually confined to the local machine. |
