Software limitations and their workarounds

Top

 

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


 
Communication problems with the engine when using IPv6
If you are using Dynamic Workload Console in environments where you are using the IPv6 protocol or in mixed environments where both the IPv4 and IPv6 protocols are in use, you might experience connection problems.

Workaround: To fix this problem set a configuration parameter in the application server, as follows:

  1. Open the following file for editing: $TWA_HOME/eWAS/profiles/jazzsm_profile/config/cells/jazzsm_cell_name/ nodes/jazzsm_node_name/servers/server1/server.xml
  2. Locate the variables: java.net.preferIPv4Addresses and java.net.preferIPv6Addresses
  3. Set the variables as follows:
    Pure IPv6 environment
    java.net.preferIPv4Addresses=false
    java.net.preferIPv6Addresses=true
    Pure IPv4 environment
    java.net.preferIPv4Addresses=true
    java.net.preferIPv6Addresses=false
    Mixed IPv4 and IPv6 environments
    java.net.preferIPv4Addresses=false
    java.net.preferIPv6Addresses=false
  4. Stop and restart the application server, using the commands stopappserver and startappserver


Job stream editing limitations with IBM Workload Scheduler for z/OS
In Dynamic Workload Console for z/OS there is no job stream editor available to manage jobs within the job stream in a plan. As a consequence, on z/OS, there is no Submit and Edit option available within the Predefined Job Stream action.

Incorrect selection of jobs in manage browsed workstations panel
In the panel to manage browsed workstations, when you select Jobs from the More Actions menu, the displayed list shows all the jobs belonging to job streams defined on the selected workstation, and not just the jobs running on it.

Special character validation problems with IBM Workload Scheduler for z/OS
In z/OS environments, during task creation or editing, a few special characters might not be validated by Dynamic Workload Console. As a consequence, an error might occur on the z/OS connector causing the result table of the task to be empty. This happens when the code page of the z/OS engine is not the same as the code page of the z/OS connector client. Invalid characters are those that map the hexadecimal values 0x7B, 0x5B, 0x7C in all supported EBCDIC code pages (for example #, $, @ for IBM-37 EBCDIC codepage).

Stop of application server hangs
The command that stops the embedded WebSphere Application Server hosting Dynamic Workload Console might hang or end due to a timeout. This can occur randomly after several days of activity. It might be necessary to stop the server manually. The server process ID to stop is stored in the following file: $TWA_HOME/eWAS/profiles/jazzsm_profile/logs/ffdc/dwc_server_name.pid

Bookmarked tasks may not work using Internet Explorer
If you have tasks bookmarked with Dynamic Workload Console "Add to bookmark" feature, this might not work with the new Dynamic Workload Console version. You can use another browser to use the feature.

What if: update screen help "Show Job" (128426)
In the contextual online help for the General Filter for Jobs panel, the name of the field "Exclude complete" should read "Exclude completed (z/OS only) and Until first completed (distributed only)"

Launching a portlet results in error message: "This portlet page is not ready. Please try again.".
When launching a portlet, such as clicking the Manage Engine link from the single entry point page from the Dynamic Workload Console, or when launching the Dynamic Monitoring Query portlet from Application Lab, the portlet does not respond immediately and returns the error message: "This portlet page is not ready. Please try again." Repeating the request several times eventually produces the portlet and its contents correctly.

Dynamic Workload Console workload dashboard unable to establish a connection with the master domain manager
Unexpected security exception in Dynamic Workload Console SystemOut.log due to security exception after a trusted login

Adding a new dependency from the Monitor Workload entry the search does not work correctly if there is more than one job stream with the same name
When trying to add dependencies to a job or a job stream from the Monitor Workload entry, if the job stream selected in the search panel has the same name as another job stream, the search reports all jobs related to all job streams with the same name.

IBM Jazz for Service Management Dashboard Application Services Hub (DASH) in high availability mode becomes unresponsive during workload execution with hundreds of users accessing the database simultaneously
When multiple threads access the database to retrieve the data, it makes the system become unresponsive. This is a known DASH problem and a workaround to resolving the problem is documented in the technote IBM Jazz for Service Management DASH hub in HA mode becomes unresponsive during workload execution with more than 300 users accessing the database simultaneously.

Dynamic Workload Console installation fails on Windows 10 (166339)
Dynamic Workload Console installation fails on Windows 10 if JazzSm is installed in a virtual directory (i.e. C:\Program Files). A pop up appears asking for the credential, to circumvent the problem, insert the JazzSm credentials or install both Dynamic Workload Console and JazzSm in a non-virtual directory.

Application Lab limitation by using Internet Explorer (156948)
If both Application Lab and Workload Designer panels are opened and you take action in the Application Lab (i.e. enhance your workload), the objects shown in the panels could not be the same, if you are using Internet Explorer.

Production and forecast plan reports do not work by using REST API (168178)
Dynamic Workload Console v9.4 uses REST API protocol, but production and forecast plan reports do not work with this protocol. To circumvent the problem, run reports by using reportcli command. The fix will be available in a short period of time and the link to download the fix will be provided.

The import Workload Application Template panel is not shown when there is only one engine (168208)
The workaround is to define another engine or duplicate the same engine with a different name.

 


Tivoli Common Reporting

Top

Tivoli Common Reporting is an optional integration service of Jazz for Service Management, which is installed with WebSphere Application Server.

 

Before you install the Reporting Services package, ensure you run IBM Prerequisite Scanner. IBM Prerequisite Scanner is a stand-alone prerequisite checking tool that analyzes system environments before the installation or upgrade of an IBM product. For more information, see the section about running the Prerequisite Scanner manually in the Jazz for Service Management documentation. For detailed information on Tivoli Common Reporting available within the Dynamic Workload Console, see the Tivoli Common Reporting Reports
