The following explains how to change the IP address and host name of the Systemwalker Operation Manager server. Also, it explains the items you must change.
Procedure
Use the following procedure to change the IP address and host name of the Systemwalker Operation Manager server.
Before changing the IP address and host name of the Systemwalker Operation Manager server, check the points of server and clients you must change by referring to "Items You Must Change".
You may need to shut down or restart the Operation Manager server other than the one whose IP address and host name you change. Check the items carefully.
Shut down Systemwalker Operation Manager both on the server whose IP address or host name you will change and on the server where you must shut down Systemwalker Operation Manager due to change of its items.
Change the IP address and/or host name of the Systemwalker Operation Manager server.
Change the items on the Systemwalker Operation Manager server or client.
Restart both the server where you have shut down Systemwalker Operation Manager and the Systemwalker Operation Manager server whose IP address and/or host name has been changed.
Items You Must Change
When changing the IP address and/or host name of the Systemwalker Operation Manager server, you must check or change the following items.
Defining the Power Control (if the batch power control is used or if the server is turned on by the client)
Defining a Monitoring Permitted Host (if multi-servers are monitored)
Defining the requesting host name and the default host name (if network jobs are used)
Defining a Trust Host (if the trusted host has been defined)
Defining a node name in the operation information (if the cluster system configuration has been defined)
Defining the configuration host name (if the Distributed Execution function or the Previous Load Distribution function is used)
Defining the Process Monitoring function (if the process monitoring has been defined)
Setting the message event destination (if a message is generated by the command)
Defining a calendar (For the cluster system configuration).
Defining the logical IP address of operation information (For the cluster system configuration).
Defining a demand job (When using the network job).
Defining Master Schedule Management [UNIX] (if the Master Schedule Management function is used)
Defining a Monitored Host
If you have changed the IP address or host name of the Systemwalker Operation Manager server, you must change the definition of the Monitored Host on all servers which monitor or operate the Systemwalker Operation Manager server you have changed.

It is required to set the changed IP address for each of the operation node and standby node [Windows]. For details, see "Setting IP address for job execution control" in the Systemwalker Operation Manager Cluster Setup Guide for Microsoft Cluster Server for Windows.
Defining a demand job
When the Operation Manager Server whose IP address or host name has been changed is the destination of network job submission, confirm the following definitions of demand job and set the changed host name on the Operation Manager Server which is the source of network job.
Set this host name when the corresponding job is not running. To activate this setting, no restarting is required.
Edit Job Information/Submit-Additional Information-Execution Server Name
A host name specified for -rh option of qsub command.
A host name specified for connect control statement in JCL.
Theo host name specified for -rh option in the second argument of job input API (MP_SubmitJob)
For details, see the following manuals. "qsub Job Submit Command" in the Systemwalker Operation Manager Reference Guide and "Registering Demand Job in Job Folders" in the Systemwalker Operation Manager User's Guide
Defining Master Schedule Management [UNIX]
If the host name or IP address is changed for an Operation Manager server where a Master Schedule Management environment has already been created, then the definitions will need to be changed.
If you have changed the IP address of the management server:
Execute the stemConfig command on the management server and on all schedule servers, and change the definition.
If you have changed the IP address of a schedule server:
Execute the stemConfig command on the management server and change the definition.
Alternatively, edit the schedule server using a Master Schedule Management Environment Setup dialog box connected to the management server.
If you have changed the host name of the management server:
Edit all of the schedule servers using a Master Schedule Management Environment Setup dialog box connected to the management server. Do not change the IP address of each schedule server, but click OK to register the schedule servers again.
If you have changed the host name of a schedule server:
In a Master Schedule Management Environment Setup dialog box connected to the management server, clear the host name of the schedule server, and add the new host name to the schedule server.
If the host name of the schedule server has been changed, the Master Schedule Management function will treat the schedule server as a different host.
Refer to the Systemwalker Operation Manager Reference Guide for details on the stemConfig command, and refer to the Systemwalker Operation Manager User's Guide - Master Schedule Management for details on the Master Schedule Management Environment Setup dialog box.
