Enabling 64–bit mode on all z/OS servers

If you have z/OS® servers that are running in 31–bit mode, you can run a script to convert all of your application servers to 64–bit mode.

Before you begin

About this task

To convert your 31–bit mode servers to 64–bit mode, you can run the updatezOS31bitTo64bit.ant script on the deployment manager profile.

Procedure

  1. Run the script to convert all of your application servers to 64–bit mode.
    /WebSphere/ND/DeploymentManager/bin/ws_ant.sh -file 
    /WebSphere/ND/DeploymentManager/profileTemplates/xd_augment/actions/updatezOS31bitTo64bit.ant  
    -DWAS_HOME/WebSphere/ND/DeploymentManager  -DprofilePath/WebSphere/ND/DeploymentManager/profiles/default
  2. Synchronize the changes to all of the nodes. For more information about synchronizing nodes, see Synchronizing nodes with the wsadmin tool and Managing nodes.
  3. Restart your application servers. For more information about starting servers, see Starting an application server.

Results

Your z/OS application servers are running in 64–bit mode.
