Additional Process Engines

To improve performance, you may eventually want to add another Process Engine to your system. You can add up to ten additional Process Engines. Note that if you currently have only one Process Engine, the workflow database it uses must be remote in order for you to add an additional Process Engine.

CAUTION Once added, you cannot remove an additional Process Engine.

NOTE (FileNet Web Services Client and Open Client only) If you have a Process with Imaging deployment, you cannot use the procedure below to add a Process Engine. Instead, first use fn_edit to add an application server and a SQL service to the new Process Engine (see your FileNet Image Services documentation for details). Then complete the procedure titled "Configure Image Services to support Process Engine(s)" in the Process Installation Guide for FileNet Image Manager.

To add a new Process Engine

  1. On the primary Process Engine:
    1. Add an entry to the hosts file. The hosts file must contain the PC server name and Internet Protocol (IP) address of all computers this Process Engine will communicate with remotely, including the database server and primary and additional Process Engines. 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 Solaris, the file is in /etc/hosts.
    2. Stop the Process Service.
    3. Select the Additional Process Engines folder, then click New on the Action menu.
    4. Enter the General properties.
      Property Description
      Server Name The name of the additional Process Engine. You cannot change the server name once it has been configured. The name must meet the Process Engine naming requirements.
      IP Address

      The IP address of the Process Engine.

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

      • Do not change a server’s IP address while another server in the VWService is in the process of being deleted.
      • If you are using the Domain Name System (DNS), make sure that you update the DNS server host table to correspond to the changes you make.

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

    5. Enter the Database properties.
    6. Name Description
      Instance Name

      (SQL Server only) The name of the SQL Server database instance on the remote server. This is set at installation, and cannot be changed. A blank instance name indicates the default instance. The name must meet the Process Engine naming requirements.

      NOTE If the remote database is installed across a subnet and referenced by an alias, the alias name must include both the remote server name and the instance name.

      Database Name (SQL Server only) The database name created during installation of the SQL Server database. The name must meet the Process Engine naming requirements.

      Dedicated Filegroup/
      Tablespace

      The name of the filegroup (SQL Server) or tablespace (Oracle) where you want the Process Engine database to reside. The name must meet the Process Engine naming requirements.

      Index Tablespace (Oracle only) Optionally, the name of the tablespace where you want the Process Engine database to store its index data. The name must meet the Process Engine naming requirements.
      Version Number (Oracle only) The version of the database software.
    7. Click OK.
    8. Restart Process Service.
  2. On the database server, create the database instance. See the appropriate database installation procedures in either the FileNet P8 Installation Guide or the Process Installation Guide for FileNet Image Manager, depending on the type of system you have.
  3. On the additional Process Engine:
    1. Install the Process Engine software, specifying the server as an additional Process Engine. For installation instructions, see either the FileNet P8 Installation Guide or the Process Installation Guide for FileNet Image Manager, depending on the type of system you have.
    2. Start the Process Task Manager.
    3. Select the Process Service node, then select Update Configuration from the Action menu.
    4. Start the Process Service.
