Activities for migrating a standalone application server
to WebSphere® Application Server Version 7.0
after you generate the appropriate Job Control Language (JCL) jobs
include activities related to general preparation, transaction-log
clearance, and node migration. Use the following checklist as a quick
reference to these activities. Follow the instructions that were generated
by the z/OS® Migration Management Tool or the zmmt command
to complete the process of migrating your standalone application server
to Version 7.0.
About this task
Key similarities to migrating a deployment manager:
- You must still create CNTL and DATA datasets.
- You must still allocate and mount a new configuration file system
to act as the target for the new Version 7.0 configuration, either
manually or using the BBOMBHFS or BBOMBZFS job.
- You must still run the BBOWMG3B job to perform the migration.
Key differences from migrating a deployment manager:
- You must clear the transaction logs using the BBOWMG1B job; you
do not have to complete this step for a deployment manager migration.
- You must disable Peer Restart and Recovery (PRR) mode using the
BBOWMG2B job; you do not have to complete this step for a deployment
manager migration.
- There is no deployment manager node to migrate.
Procedure
- Prepare to migrate the application server.
- Clear the transaction logs for the application server node.
