Migrating to a WebSphere Extended Deployment Compute Grid Version 6.1 cell

This topic describes how to migrate a WebSphere® Extended Deployment Version 6.0.2 cell to a WebSphere Extended Deployment Compute Grid cell.

Before you begin

You must have a WebSphere Extended Deployment Version 6.0.2 Compute Grid cell that you want to migrate.

About this task

Follow these steps to upgrade your existing WebSphere Extended Deployment Version 6.0.2 Compute Grid cell to a WebSphere Extended Deployment Version 6.1 Compute Grid cell.

Procedure

  1. Install WebSphere Application Server Version 6.1 on the workstation hosting the deployment manager.
  2. Create a Version 6.1 deployment manager profile. The profile name must match between the Version 6.0.2 cell and the new Version 6.1 cell
  3. Install WebSphere Virtual Enterprise and WebSphere Extended Deployment Compute Grid on the workstation hosting the Version 6.1 deployment manager. Augment the deployment manager profile.
  4. Migrate the deployment manager by using the WASPreUpgrade and WASPostUpgrade utilities. See the WebSphere Application Server Version 6.1 migration tools migration tools topic in the WebSphere Application Server Information Center.
  5. Create a Version 6.1 scheduler managed node and Version 6.1 execution endpoint managed node on the WebSphere Extended Deployment Version 6.1 workstation.
    1. Federate those nodes into the cell.
    2. Augment the profiles with the xd_augment or wxdcg_augment augmentations.
    The Version 6.1 scheduler managed node will host the Job scheduler application, and the Version 6.1 execution endpoint managed nodes will (later) host the WebSphere Extended Deployment Compute Grid endpoint application and your compute grid applications.
  6. Use the appropriate Migrate*.ddl in the ${was.install.root}/longRunning directory to migrate the lree and lrsched datasources that migrated from the WebSphere Extended Deployment Version 6.0.2 cell.
  7. Uninstall the LongRunningScheduler application which migrated from the WebSphere Extended Deployment Version 6.0.2 cell. WebSphere Extended Deployment Version 6.1 requires a Version 6.1 job scheduler.
  8. Configure the Version 6.1 job scheduler using the JobScheduler panel of the administrative console. Configuring the Version 6.1 job scheduler causes the Version 6.1 LongRunningScheduler application to be installed.
  9. Perform WebSphere Extended Deployment migration on the deployment manager. You can use the XDPreUpgrade command .
  10. Start the WebSphere Extended Deployment Version 6.1 nodes.
  11. Start the WebSphere Extended Deployment Version 6.0.2 execution endpoint node. Do not start the Version 6.0.2 job scheduler node.

Results

Jobs can be dispatched from the Version 6.1 job scheduler to run on the WebSphere Extended Deployment Version 6.0.2 grid endpoints. New applications can be installed in the WebSphere Extended Deployment Version 6.1 endpoint nodes and dispatched to those endpoints. The process of installing a J2EE batch/compute-intensive application into a WebSphere Extended Deployment Version 6.1 endpoint node will cause the grid endpoint application to be installed to that endpoint if that application does not already exist.
