Configure Process Engine server general properties

Use the General tab to configure the general properties for the Process Engine server.

The General tab includes these fields:

Name Description

IP address

The IP address of the local Process Engine server.

NOTE  If you change the IP address, you should back up the Process Engine configuration files.

You can safely change a server's IP address without affecting Process Engine, provided the following rules are observed:

  • If you are using the Domain Name System (DNS), you must update the DNS server host table to correspond to the changes you make.
  • You must update the hosts file on the related servers. The hosts file must contain the PC server name and IP address of all computers this Process Engine server will communicate with remotely, including the database server. The location of the hosts file depends on where the operating system software is installed; for example, for Windows the file might be in \winnt\system32\drivers\etc, for UNIX, the file is in /etc.
  • If the server is part of a farmed Process Engine system, you must update your load balancer configuration with the new IP address.

For instructions on changing your server's IP address, see the documentation for your server platform.

Number of VWKs processes

Sets the number of VWKs server processes to run on the Process Engine server. The default is five processes.

The main purpose of having multiple VWKs processes is to take advantage of multiple processors. Each VWKs process consumes approximately 6 to 8 MB of memory on the Process Engine server. IBM recommends 1.5 to 2 VWKs processes per CPU. For example, a single-CPU system should configure the Process Engine server for two VWKs processes; a quad-CPU system should configure six to eight VWKs processes.

If all VWKs processes are processing other requests, Process Engine queues new incoming requests and waits for an available process. If you lower the current setting for this option, Process Engine removes each VWKs process as soon it completes the current request, until the number of processes equals the setting.
