Preparing to migrate a z/OS standalone application server

Preparing to migrate a standalone application server node to WebSphere® Application Server Version 7.0 includes activities related to inventorying your existing configuration as well as generating CNTL and DATA datasets that you will use in the actual migration.

Before you begin

Read Overview of migration, coexistence, and interoperability and Premigration considerations.

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 WebSphere Application Server, Network Deployment application server node.

WebSphere Application Server Version 7.0 supplies eight migration jobs in the target dataset that you allocate when you generate your migration jobs. Use these jobs to perform the actual migration.
  • BBOWMG1B
  • BBOWMG2B
  • BBOMBHFS or BBOMBZFS
  • BBOWMG3B
  • BBOWBPRO
  • BBOWBPRE
  • BBOWBPOS
  • BBOMBCP

Procedure

  1. Inventory your configurations.

    Print this procedure, and enter the values for your configurations in the appropriate columns of the following tables.

    • Table 1. WebSphere Application Server for z/OS Version 5.1.x or Version 6.x configuration general information. . Table containing WebSphere Application Server for z/OS Version 5.1.x or Version 6.x configuration general information.
      Item Value                                                              
      Cell short name:  
      Cell long name:  
      Sysplex name:  
      Location of original Version 5.1.x or Version 6.x configuration datasets:  
      WebSphere Application Server Version 5.1.x or Version 6.x home directory (configuration file system):  
    • Table 2. WebSphere Application Server for z/OS® Version 5.1.x or Version 6.x standalone application server node. . Table containing WebSphere Application Server for z/OS Version 5.1.x or Version 6.x standalone application server node.
      Item Value                                                              
      Configuration mount point:  
      Configuration file system dataset:  
      Home directory:

      Default: /AppServer

      Your value: ___________________

      WebSphere Application Server SMP/E home:

      Default: /usr/lpp/zWebSphere/V5R1M2

      Your value: ___________________

      Controller Job Control Language (JCL) start procedure:  
      Servant JCL start procedure:  
      Daemon JCL start procedure:  
    • Table 3. WebSphere Application Server Version 7.0 installation information. . Table containing WebSphere Application Server Version 7.0 installation information.
      Item Value                                                              
      Product dataset HLQ:  
      Product directory (SMP/E target for Version 7.0):  
      WebSphere Application Server Version 7.0 in LPA/LNKLST?:

      __ No

      __ Yes

  2. Produce migration CNTL and DATA datasets for the node.

    You must provide a set of CNTL and DATA datasets for the migration utilities to read in order to perform the migration. Generate a set of customized jobs for the node in your configuration that you want to migrate.

    Some important points about these steps:

    The purpose of creating these customized CNTL and DATA datasets is to give the migration utilities access to key information about your new Version 7.0 configuration as well as access to shell scripts customized with this new information. The migration utilities get the bulk of the configuration information from your existing Version 5.1.x or Version 6.x configuration file system.
