Preparing to migrate a standalone application server node to Version 6.0.x

Preparing to migrate a standalone application server node to WebSphere Application Server for z/OS Version 6.0.x includes activities related to inventorying your existing configuration as well as generating CNTL and DATA data sets for the migration utilities.

About this task

Migrating a standalone application server node is relatively simple because it consists of a single server and a daemon:

You might have configured multiple application servers inside a standalone application server node. Generally, this configuration is not recommended. But, if you have this configuration, the migration utilities will migrate all servers in the node, just as it would all the servers in a Network Deployment application server node.

WebSphere Application Server for z/OS Version 6.0.x supplies five migration utilities in the data set that you specify during the "Allocate target data sets" step in the Customization Dialog (see Frequently asked questions about the migration process for a description of each utility):
  • BBOWMG1B
  • BBOWMG2B
  • BBOWMBMT
  • BBOWMG3B
  • BBOMBCP

These are the jobs you will use to perform the migration.

Procedure

  1. Inventory your existing configuration.
    • WebSphere Application Server for z/OS Version 5.x configuration general information:
      Cell short name:  
      Cell long name:  
      Sysplex name:  
      Location of original Version 5.x configuration data sets:  
      WebSphere Application Server Version 5.x home directory (configuration HFS):  
    • WebSphere Application Server for z/OS Version 5.x standalone application server node:
      Configuration mount point:  
      Configuration HFS data set:  
      Home directory:

      Default: /AppServer

      Your value: ___________________

      WebSphere Application Server SMP/E home:

      Default: /usr/lpp/zWebSphere/V5R0M2

      Your value: ___________________

      Controller JCL start proc:  
      Servant JCL start proc:  
      Daemon JCL start:  
    • WebSphere Application Server for z/OS Version 6.0.x installation information:
      SMP/E data set HLQ:  
      SMP/E HFS Mount Point:  
      WebSphere Application Server Version 6.0.x product directory (SMP/E target for Version 6.0.x):  
      WebSphere Application Server Version 6.0.x in LPA/LNKLST?:

      __ No

      __ Yes

  2. Produce skeleton migration CNTL/DATA for the node.

    You must provide a set of CNTL and DATA data sets for the migration utilities to read in order to perform the migration. To do this, use the ISPF Customization Dialog for Version 6.0.x to generate a set of customized jobs for the node in your configuration.

    Some important points about these steps:
    • You will be submitting these customized jobs
    • When you go through the panels to generate these customized data sets, on most of the panels it will be necessary to supply information related to your configuration. This information is used to generate your customized jobs.

    The purpose of creating these customized CNTL and DATA data sets is to give the migration utilities access to some key information about your new Version 6.0.x configuration (for example, mount points and paths), as well as access to shell scripts customized with this new information. As illustrated here, the migration utilities get the bulk of the configuration information (for example: settings and applications) from your existing Version 5.x configuration HFS.

    For a detailed description of what you must do in the Customization Dialog to create your customized CNTL and DATA data sets, see Customization Dialog walk-through for migrating a standalone application server node.
