CA Workflow Considerations

Before you install CA Workflow, consider the following information to help ensure a successful implementation:

• AIX (Primary Server) and the Java Runtime Environment (JRE)—On AIX for the primary server, CA Service Desk Manager installs the IBM version of the Java Runtime Environment (JRE) in the SC directory. The cryptography functionality in this JRE is limited, and in its current form must be updated to enable the CA EEM authentication feature and CA Workflow. You can download the full-featured cryptography features from the IBM website. Download the IBM SDK Policy Files, otherwise known as Unrestricted JCE Policy files for SDK 1.5.

  On the primary server, complete the following steps:

  1. Shut down CA Service Desk Manager.
  2. Copy the following JRE 1.5 folder from the installation media to a folder you specify:

     /aixsrvr.cd1/ca_tps.aix/JRE_1_5/jre

     The CA Service Desk Manager privileged user needs execute permissions on this folder and its contents.

     Note: You specify this JRE folder location in NX.env in the following Step 4.

  3. Replace the policy JAR files in the lib/security directory using the policy JAR files from the IBM website.
     1. Navigate to the IBM website at the following location:

        http://www.ibm.com/developerworks/java/jdk/security/50/

     2. Click the IBM SDK Policy Files link and follow the download instructions.
     3. Install the JAR files and replace the policy JAR files in the lib/security directory.
  4. Add the following entry to NX.env:

     NX_JRE_INSTALL_DIR_CAWF=<JRE 1.5 folder>

  Note: Replace <JRE 1.5 folder> with the location specified in the previous Step 2. For example, NX_JRE_INSTALL_DIR_CAWF=/opt/testDVD/aixsrvr.cd1/ca_tps.aix/JRE_1_5/jre

  1. Restart CA Service Desk Manager services.

     You are now able to log in to CA Workflow. If necessary, use the CA Workflow design environment (IDE) to load/import manually the process definitions and actors shipped by CA Service Desk Manager. The process definitions and actors can be found in $NX_ROOT/data/workflow on the primary server.

  • CA MDB Database User or Password—Consider the following information:
    • If you change either the CA MDB database user or password after the initial CA Service Desk Manager installation, rerun the CA Workflow installation so CA Workflow applies the changes and can communicate with CA Service Desk Manager. When you rerun the CA Workflow installation, CA Service Desk Manager automatically sets the new user name or password for CA Workflow and you are not able to change the values manually during the CA Workflow installation.

    Note: Oracle environmental variables must be set before installing CA Workflow on UNIX and Linux. If the ORACLE_HOME variable is not set, you receive an error message when clicking the install link.

    • If you are migrating to a new database, run the Workflow Migration Utility.
  • IPV6—If your Linux server is configured for IPv6 support, you might be unable to log in to the CA Workflow IDE. To correct this situation, modify the ide.sh script file located in $NX_ROOT\site\Workflow\Client by changing the second line which reads: "VMARGS=" to read: "VMARGS=-Djava.net.preferIPv4Stack=true". Then, save the script file and start the CA Workflow IDE again.
  • Tomcat—Consider the following information:
    • If you have any difficulties with Tomcat being started, and as a result, the CA Workflow and web interface are not available, increase the Tomcat memory.

    Note: For information about how to address this situation, search for the Knowledge Base Article TEC418959 on http://ca.com/support.

    • During the installation of CA Workflow, CA Service Desk Manager and CA EEM share a separate port number for Tomcat. If you have any difficulties with Tomcat when installing or using CA Workflow, stop and restart the service.
    • If you have installed and changed the installation defaults for the Tomcat port (8080) or the default privileged userid/password (ServiceDesk/ServiceDesk), make the following changes to the default CA Workflow definitions/actors so they work properly.
  1. Log on to Workflow IDE.
  2. Complete the following steps to modify the default Service Desk Web Service Actor:
     1. Click the Actors tab.
     2. Expand the Web Service tree.
     3. Right-click the Unicenter_Service_Desk_Web_Service actor and select Properties.
     4. Select and copy the content of the WSDL URL entry.
     5. Modify the Name of the Actor and click OK.
     6. Right-click the Web Service Tree and select Add Actor.
     7. In the Name field, enter Unicenter_Service_Desk_Web_Service.
     8. In the WSDL URL entry, paste the previously copied content.
     9. Modify the port number in the URL to match the Port Number selected during the Tomcat configuration.
     10. Click OK.
