Dynamic Workload Console: compatibility

Compatibility considerations

When you have a backup master domain manager at the V9.5FP2 version level, but the master domain manager is still at a previous product version level, problems can occur when monitoring objects that support the definition in a folder such as, prompts, workstations, and resources, as well as objects that contain the workstation in their object identifier, for example, job streams. More specifically, these objects are not displayed in the results of the monitoring query on the plan if you use filters in your query.

Solution: Upgrade the master domain manager to the V9.5FP2 level, and then run planman resynch to resolve the issue.

IBM Workload Scheduler for z/OS: compatibility

To find the fix packs released for IBM Workload Scheduler, and the Dynamic Workload Console including links to the related readmes files, see Fix Central.

This section contains product limitations not resolved with this release of Dynamic Workload Console, and their workarounds (where applicable)

Application Lab starts by connecting to the first engine of the manage list.

When running Application Lab from the welcome page, it automatically connects to the first engine set in the manage list. Workaround: To connect to a different engine, replace the engine name and engine owner in the URL.

The Dynamic Workload Broker user interface and command line are not supported for the current release

The listed components, also known as Broker CLI and Broker UI, are not supported in version 9.5. To be able to use these components, install version 9.5, Fix Pack 1 or later.

 Note: The Broker CLI and the Broker UI require both the Dynamic Workload Console and the master domain manager at the Version 9.5, Fix Pack 1 level or later.

Browser limitations

-If you use the Workload Dashboard with Firefox, by clicking on a bar chart there is no drill-down on the objects selected.
-To optimize performance when using the Graphical Views it is recommended to use Chrome or Firefox.

Workload Dashboard

You cannot launch more than one dashboard that requires an engine selection at a time. Use a new session for each dashboard.

Limitations with Workflow Folders

- The folders are not available with cross dependecies and reports. 
- In the Workload Designer when opening a job plugin in view mode, folder field does not appear. Workaround: Open the job plugin in edit mode.
- Limited number of objects in Workload Designer: when clicking the tab Explore in the Workload Designer, the maximum number of jobs, job streams and folders that can be displayed is 250 for each object type.
- Shadow Jobs and SAP Jobs on Dynamic Agent in folders: These jobs can only be saved in the root folder.

The status of a job changed within a rerun chain does not appear in the Dynamic Workload Console

When you modify the status of a job within a rerun chain using conman confirm, and the job is not the last job in the chain, the status is correctly displayed in conman, but remains unchanged in the Dynamic Workload Console. However, because the job in object is not the last job in the chain, this modification does not affect the overall job stream status.

Launch in context not supported

The Launch in context is not supported for this version of the Dynamic Workload Console. 

Backward compatibility problems with IBM Workload Scheduler 9.4
- To monitor objects from an engine version 9.4 remove the folder filter from the the predefined query.
- Before importing preferences from the Dynamic Workload Console 9.4 perform the following procedure:

open the TDWCSettings.xml file and find and replace as follows:

find:
<java.lang.String id="PARAM_EngineType">distributed</java.lang.String>
replace with
<java.lang.String id="PARAM_EngineType">tws-distributed</java.lang.String>

find:

<java.lang.String id="PARAM_EngineType">zos</java.lang.String>
replace with
<java.lang.String id="PARAM_EngineType">tws-zos</java.lang.String>

 Poor performance for Dynamic Workload Console dashboards containing both distributed and Z engines

Using a Dynamic Workload Console dashboard containing both distributed and Z engines, might affect product performance negatively, especially on the distributed database server, leading to high CPU consumption.

Workaround: Create separate dashboards for distributed and z/OS environments.

The following are limitations that affect the installation and upgrade of the Dynamic Workload Console:

Characters allowed for password

Windows environment: The following are valid characters to be used in the password: alphanumeric, dash (-), underscore (_) characters, and ()|?*~+.

UNIX environment: The following are valid characters to be used in the password: alphanumeric, dash (-), underscore (_) characters, and ()|?=*~+.

The installation directory name and path cannot include non-ASCII characters
           Recent JVMs do not fully support use of non-ASCII characters with the -jar and -javaagent commands. Use only ASCII characters in your installation directory names and paths.

Migration of roles from the Dynamic Workload Console
           The migration of the roles from the Dynamic Workload Console Version 9.4 to Version 9.5 is not supported. The user have to recreate the roles in the latest version.

All updates to the IBM Workload Scheduler documentation that are required for version 9.5 are included in the editions of the publications at the IBM Knowledge Center.
