Starting DWA on Linux systems

To start running IBM® Engineering Requirements Management DOORS® - Web Access (DWA), you must start its components in a specific order.

Before you begin

Review the Installation roadmap for DWA and related help topics for prerequisites, installation topology and minimum requirements, and license options.

Before you start the interoperation server, you must set up a valid DISPLAY variable and then make it accessible to the user who starts the interoperation server. You can use either an X server or virtual DISPLAY with a solution, such as Xvfb.

Attention: Do not use a remote DISPLAY variable. If you export a DISPLAY variable from another system for the interoperation server to use, the interoperation server becomes vulnerable to network interruptions. These interruptions can stop the interoperation server and cause DWA to fail.

If your version of DWA is earlier than 9.5.2.1, then see this topic in a previous version of the help.

About this task

If users and groups are managed in IBM Rational® Directory Server, and the directory server is backed up or restarted, users cannot log in to the web client until all of the interoperation servers are restarted.

For instructions to start DWA on Linux systems when the server starts, see technote 1420620.

The Derby installation supports data exchange and reporting that uses tracked resource sets (TRS) and the Lifecycle Query Engine (LQE). For more information, see Tracking changes by using TRS and LQE

Procedure

  1. If your system is configured for data exchange and reporting, start the Derby database server. Browse to the directory where you installed DWA and run derby.start.sh.
    Important: If you use a Derby port number other than the default port 1527, you must change the value of the DERBY_PORT variable in the derby.start.sh script before you run the script. Also, add this command line parameter to the script: -Dderby.drda.portNumber=%DERBY_PORT%. Alternatively, you can add the following entry with the new port number in the derby/derby.properties file: derby.drda.portNumber=derby_port_number.
  2. Start the web access broker:
    1. On the computer that hosts the web access broker, log in as the owner of DWA.
    2. Go to the directory where you installed DWA.
    3. Enter broker.start.sh.
  3. If the IBM Engineering Requirements Management DOORS (DOORS) database server is not already started, start it.
  4. Configure and start the interoperation server:
    1. On the computer that hosts the interoperation server, log in as the owner of DWA.
    2. Set these environment variables:
      DOORSHOME=doors-home-path
      DOORSDATA=36677@myserver
      PATH=$DOORSHOME/bin:$PATH
      export DOORSHOME PATH DOORSDATA

      Where the DOORSHOME variable relates to where the interoperation server is installed. This variable might be different from the DOORSHOME variable that you use for the database server.

    3. Browse to $DOORSHOME/bin and start the interoperation server by entering its command-line attributes in this format:
      ./doors9 -interop -data port@myserver -brokerHost myBroker -brokerPort brokerport &
      Where
      • port is the port number that the DOORS database server is using.
      • myserver is the name of the system where the DOORS database server is installed.
      • myBroker is the name of the system that hosts the broker.
      • brokerport is the port that the broker is using, which by default is 61616.
      For more startup options, see Command-line switches for the DOORS client and interoperation server.
  5. Start the web access server:
    1. On the computer that hosts the web access server, log in as the owner of DWA.
    2. Go to the directory where you installed DWA.
    3. Enter server.start.sh.
