You can migrate a job manager profile and its registered
set of servers from Versão 7.0 ou posterior to Versão 9.0.
About this task
Job manager profiles can have one or more of the following
server types registered:
- Deployment manager servers
- Managed base application servers (which are also registered to
an administrative agent)
Evitar Problemas: - Managed base application servers and deployment manager servers
cannot accept jobs from a job manager that is of a previous version.
To avoid problems, migrate your job manager profiles to Versão 9.0 before you migrate
managed base application servers and deployment manager servers to Versão 9.0.
- When migrating the managed base application server or managed
deployment manager in a flexible management environment, the node
names must be the same in Versão 9.0 and the previous releases.
gotcha
Procedure
- Back up the current job manager configuration by running the backupConfig
command.
The backupConfig command saves the job manager configuration to a file that
you can use later for recovery purposes.
- Change to the job_manager_profile_root/bin
directory.
- Run the backupConfig command with the appropriate parameters on the job
manager. For example:
/opt/WebSphereV70/profiles/jobMgr01/bin/backupConfig.sh /mybackupdir/jobMgrBeforeV90migration.zip
-username myuser -password mypass -nostop
Alternately, you can use the PAX command to back up all HFS files. For more information, see
Using the z/OS UNIX pax command.
- Install WebSphere Application Server para z/OS®
Versão 9.0 onto each target host.
For more information, see the installation documentation.
- Specify the new job manager migration configuration in the z/OS Migration Management
Tool.
Use the z/OS Migration Management Tool to create a migration definition and upload the jobs for
migrating the job manager.
Evitar Problemas: The
Versão 9.0 cell name must match
the cell name in the
Versão 7.0 ou posterior configuration. If you create a
profile with a new cell name, then the migration will fail.
gotcha
- Complete the following worksheet: Specifying a deployment manager migration configuration in the z/OS Migration Management Tool: Worksheet
- On the Migration Node Type Selection panel, select Migrate a job
manager.
- Complete the fields on the subsequent panels using the values from your worksheet.
- Review the job manager migration definition to make sure that all the values are correct.
- In the WebSphere Application Server for z/OS migration definition table, select the migration
definition that you want to review.
- Click View.
- For information about the migration definition, click the Summary,
Instructions, or Response file tab.
- Upload the migration jobs to the target z/OS system.
- Stop the job manager that you are migrating. Any jobs that exist within the old job manager database will be migrated as part of the
migration.
- Run the migration jobs for the administrative agent
Follow the instructions in the 'Migration Instructions' view of the z/OS Migration Management
Tool or in the BBOMAINS member of the CNTL dataset that you uploaded to the target z/OS system.
The CRPROF (profile create), PREUPGRD (preUpgrade) and UPGRADE steps are all executed during this
process.
- Verify all output created in the working directory of the HFS/ZFS (specified in ZMMT) and all
MVS job output created by the batch jobs.
Verify that you are getting return codes of 0, and review the log files in the
migration temporary directory on the configuration file system.
The migration temporary directory is temporary_directory_location/nnnnn,
where temporary_directory_location is the directory specified for the temporary
directory location and nnnnn is the numeric value generated for the migration
identifier when you generated your migration jobs. The default temporary directory location is
/tmp/migrate.
- Start the Versão 9.0 job manager.
Ensure that both Versão 7.0 ou posterior and Versão 9.0 of the job manager are running.
- Change to the new Versão 9.0 job manager profile
bin directory.
- Run the startServer jobmgr command.
- Check the SystemOut.log file for warnings or errors.
- Migrate the registered servers.
The Versão 9.0 job manager can manage Versão 7.0 ou posterior registered servers. For the Versão 7.0 ou posterior topology to function with the Versão 9.0 job manager, you are not required to migrate the
registered servers.
For each registered server that you plan to migrate to
Versão 9.0 perform the following steps:
Results
You migrated a job manager profile and its
associated managed base application servers from WebSphere Application Server Versão 7.0 ou posterior to Versão 9.0 using
the migration tools.
