Modify the Ports Configuration File

This section describes how to configure the protocols and ports that Arcserve Backup uses to communicate in your environment.

To modify the ports configuration file

1. Open PortsConfig.cfg using a text editor such as Notepad. You can access the file from the following directory:

   On 64-bit platform:

   (installation_drive):\Program Files (x86)\CA\SharedComponents\ARCserve Backup
   

   On 32-bit platform:

   (installation_drive):\Program Files\CA\SharedComponents\ARCserve Backup
   

2. Replace the value of ENABLE_CONFIGURABLE_PORTS from 0 to 1.
3. Add one or more lines of code using the following format:

   ServiceName(%s)    PortRange_1;PortRange_2;...;PortRange_n    [HostName(%s)]  [IPAddress(%s)]
   

   • Use one of the following formats to specify a port or port range:

     	SinglePort(number)
     	PortBegin(number) - PortNumberEnd(number)
     

   • Use the following format to specify an IP address:

     	%d.%d.%d.%d
     

   • The ServiceName is a string without spaces.
   • The HostName is a string that represents a valid computer name.
4. Close PortsConfig.cfg and save your changes.
5. After changing the Portsconfig.cfg file, restart all services affected by the changes. For all Arcserve Backup services, you can run cstop and cstart to stop and start the services.

To support backward compatibility, the keys corresponding to Arcserve Backup database agents are written to the PortsConfig.cfg file below the comment section. The database agents affected are the Tape Engine (tapeengine), the Job Engine (jobengine), and the Database Engine (databaseengine). These Arcserve Backup database agents send jobs to the Arcserve Backup queue using old ports. If you do not have old agents using old ports in your network, you can safely remove these lines from the PortsConfig.cfg file. However, you must restart each Arcserve Backup database agent service to enable communication using system ports.

Note: For more information about requirements for Microsoft Windows system services ports, see the Microsoft Support website.
