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
- Install WebSphere Application Server Version
6.1 on the workstation hosting the deployment manager.
- 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
- 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.
- 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.
- 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.
- Federate those nodes into the cell.
- 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.
- 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.
- 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.
- 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.
- Perform WebSphere Extended Deployment migration
on the deployment manager. You can use the XDPreUpgrade command
.
- Start the WebSphere Extended Deployment Version
6.1 nodes.
- 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.
