Issue/Introduction

By default, CA Message Queuing (CAM) will bind to the IP address that is the highest in the order.
Sometimes it is necessary to force CAM to bind to a different IP but changing the binding order is not acceptable.

Environment

Client Automation - All Versions

Resolution

To force CAM to bind to a different IP address

1. Determine what IP address CAM is currently binding to by issuing the command:
   
   camping -a <hostname>
   The hostname can be the local server hostname. The camping output shows the IP address that CAM is using.
   
   
2. If you need to have CAM use another IP address, run the command:
   
   camsave persist
   This will create a cam.cfg file located for Windows under %CAI_MSQ%
   
   Find the location for UNIX/Linux by issuing the command:
   more /etc/catngcampath
   
   
3. Open the file cam.cfg and add the following under the *ROUTING section:
   *ROUTING
   forward 127.0.0.1= <local IP address to use>

Example:
forward 127.0.0.1=192.a.b.c

1. Save and close the file.
   
   
2. Recycle the CA Message Queuing Server service.
   
   
3. Run the camping - a test again:
   
   camping -a <hostname>
   If the correct IP address is displayed, you are finished.
   
   
4. If the correct IP address is not showing, open the file cam.cfg again and edit the *ROUTING line as follows:
   
   forward 127.0.0.1=<local IP address to use> <local IP again>

Example:
forward 127.0.0.1=192.a.b.c 192.a.b.c

1. Save and close the file cam.cfg.
   
   
2. Recycle the CA Message Queuing Server service.
   
   
3. Rerun the camping -a test and verify that the correct address is now in use:
   
   camping -a <hostname>
