Uninstalling the IMS Server 8.2.1-ISS-SAMESSO-IMS-FP0008

When you install a fix pack for IMS Server, you can uninstall the fix pack and revert to the previous version if necessary. You can uninstall the fix pack automatically or manually.

To uninstall the fix pack and to revert IMS Server to the previous version, you must have access to the IMS Server installation files.

Uninstalling the fix pack automatically
These steps uninstall the IMS Server fix pack and automatically redeploys the IMS Server in the WebSphere Application Server.

Note: This procedure is applicable for WebSphere Application Server Version 7.0 only.

Ensure that:

• You extracted the etc-ISS-SAMESSO-8.2.1.zip file into your selected directory and copied the extracted etc folder into the root of the IMS Server installation directory.
• IMS Server fix pack is installed.
• WebSphere Application Server 7.0 is installed and running.
• IBM HTTP Server is installed and configured for the IMS Server.

Procedure
1. From the <IMS Server installation directory>\etc\ folder, open the tamesso.ims.appserver.properties file with a text editor.

2. Edit the values of these variables.

• • was.hostname=was_hostname
    was.connector.port=was_connector_port
    was.security.enabled=true
    was.admin.user.id=was_admin_id
    was.admin.user.pwd=was_admin_pw
    was.truststore.file=truststore_file
    was.truststore.pwd=truststore_pwd
    was.keystore.file=
    was.keystore.pwd=

 

• • a. Replace was_hostname with the name of your computer.

    b. Replace was_connector_port with the SOAP connector port. For example: 8880.

    • • Retrieve the SOAP connector port value from: C:\Program Files\IBM\WebSphere\AppServer\profiles\<profile_name>\logs\AboutThisProfile.txt
        
        Note: If you use WebSphere Application Server Network Deployment, <profile_name> is the deployment manager profile name.
      
      
    c. Take one of the following actions:
    • • • If WebSphere Application Server security is enabled, replace was_admin_id and was_admin_pw with your WebSphere Application Server user name and password.
        • If WebSphere Application Server security is not enabled, set the value of was.security.enabled to false.

    d. Set the truststore_file and truststore_pwd.

    • Note: Use any of these valid formats when you specify the path for the truststore file:
      • C:/.../...
      • C:\\...\\...
    • • truststore_file
        Replace truststore_file with the path where the truststore file is located. Follow the format in the tamesso.ims.appserver.properties file.
        • For WebSphere Application Server stand-alone:
        
        
        • C:\Program Files\IBM\WebSphere\AppServer\profiles\<profile_name>\config\cells\<cell_name>\nodes\<node_name>\trust.p12
          
          See the following example:
          C:\Program Files\IBM\WebSphere\AppServer\profiles\AppSrv01\config\cells\ibmusvr1Node01Cell\nodes\ibmusvr1Node01\trust.p12
        • For WebSphere Application Server Network Deployment:
        
        
        • C:\Program Files\IBM\WebSphere\AppServer\profiles\<Dmgr_profilename>\config\cells\<cell_name>\trust.p12
          
          See the following example:
          C:\Program Files\IBM\WebSphere\AppServer\Profiles\Dmgr01\config\cells\ibm-svr1Cell01\trust.p12
        
        truststore_pwd
        Replace truststore_pwd with your WebSphere Application Server trust store password.
        The default password for WebSphere Application Server trust store is WebAS.
    e. If two-way SSL is enabled, set the was.keystore.file and was.keystore.pwd.
    • Note: Use any of these valid formats when you specify the path for the keystore file:
      • C:/.../...
      • C:\\...\\...
    • • was.keystore.file
        Specify the path where the keystore file is located. Follow the format indicated in the tamesso.ims.appserver.properties file. For example:
    • • • For WebSphere Application Server stand-alone:
        
        
        • C:\Program Files\IBM\WebSphere\AppServer\profiles\<profile_name>\config\cells\<cell_name>\nodes\<node_name>\key.p12
          
          See the following example:
          C:\Program Files\IBM\WebSphere\AppServer\profiles\AppSrv01\config\cells\ibmusvr1Node01Cell\nodes\ibmusvr1Node01\key.p12
        • For WebSphere Application Server Network Deployment:
        
        
        • C:\Program Files\IBM\WebSphere\AppServer\profiles\<Dmgr_profilename>\config\cells\<cell_name>\key.p12
          
          See the following example:
          C:\Program Files\IBM\WebSphere\AppServer\Profiles\Dmgr01\config\cells\ibm-svr1Cell01\key.p12
     
    • • was.keystore.pwd
        Specify the WebSphere Application Server keystore password.
