Products in a mixed environment

Support for multiple versions of an agent that run in the same environment is provided to support a staged upgrade. However, you should be aware of certain issues while you are working with a mixed environment.

Tivoli Enterprise Portal user interface

Product information in the Tivoli Enterprise Portal reflects the level of support for applications that are installed on the portal server, not the version of the monitoring agent. After you install support on the portal for V5.3.0 monitoring agents, you will see accurate workspace and attribute information for the monitoring agent. However, for prior versions of the monitoring agents, you might see potentially misleading information in flyovers, full-text help, and information that is provided in the situation editor.

You can use the predefined dynamic workspace links provided by V5.3.0 agents to link to the workspace of a OMEGAMON® at an earlier version if the target workspace exists in that version of the product. If the target workspace does not exist, you receive the KFWITM081E message.

In cases where the target workspace has been modified (for example, to accept link parameters to limit the data that is displayed) you might notice different behavior when you upgrade the target product to V5.3.0.

OMEGAMON enhanced 3270 user interface

The current release of the enhanced 3270 user interface does not support SDA processing. If the enhanced 3270 user interface is configured in the same runtime environment as the hub address space and you plan to upgrade with an OMEGAMON agent that is not configured in this same runtime environment, it is suggested that you run the configuration load processing for both the runtime environment that contains the agent and the runtime environment that contains both the interface and the hub monitoring server and recycle the interface address space.

The OMEGAMON enhanced 3270 user interface does not support releases of OMEGAMON earlier than V5.1. Although some of the OMEGAMON V4.2.0 agents return data that is viewable in the new 3270 user interface, only the displayed data that is returned by the OMEGAMON V5.1.* and V5.3.0 monitoring agents is supported.

Users of the enhanced 3270 user interface can experience operational limitations when they are running configurations that run multiple versions of OMEGAMON agents during a staged upgrade period. Table 1 summarizes related operational considerations by product. For more information about limitations, consult the product configuration and upgrade documentation. Not all new features introduced in V5.3.0 releases will display data for prior agent versions.

Product version that provides enhanced 3270 interface support Operational considerations with multiple agent versions running
OMEGAMON for CICS® on z/OS® V5.3.0 Only data that is returned from OMEGAMON for CICS V5.1.0 and V5.3.0 agents is displayed in the enhanced 3270 user interface. Data that is returned from the V4.2.0 agents can be viewed from one of the other available interfaces: Tivoli Enterprise Portal, OMEGAMON for CICS, or OMEGAMON II for CICS.
OMEGAMON XE for Db2® Performance Expert on z/OS V5.4.0
OMEGAMON XE for Db2 Performance Monitor on z/OS V5.4.0		 Only data that is returned from OMEGAMON Db2 V5.1.1, V5.2.0, V5.3.0, and V5.4.0 agents is displayed in the enhanced 3270 user interface. Data that is returned from V5.1.0 and V4.2.0 agents can be viewed from one of the other available interfaces.
OMEGAMON for IMS on z/OS V5.3.0 Only data that is returned from OMEGAMON for IMS V5.1.0 and V5.3.0 agents is displayed in the enhanced 3270 user interface. Data that is returned from the V4.2.0 agents can be viewed from one of the other available interfaces: Tivoli® Enterprise Portal, OMEGAMON for IMS or OMEGAMON II for IMS.
OMEGAMON for Networks V5.3.0 The enhanced 3270 user interface for OMEGAMON for Mainframe Networks is designed to display data from V5.1.0 and later agents. Continue to use the Tivoli Enterprise Portal to view data from V4.2.0 agents.
OMEGAMON for Messaging for z/OS V7.3.0 The enhanced 3270 user interface for WebSphere® MQ monitoring is designed for V7.1.0 and later monitoring agents. The WebSphere MQ Health Overview will not contain Queue Manager Status rows for queue managers that are monitored by previous release agents. Some workspaces function with previous release agents, but you will not be able to navigate to them using health overview options for queue managers. Use the Tivoli Enterprise Portal interface or the old 3270 interface to view data that is produced by previous release agents.
OMEGAMON for Storage on z/OS V5.4.0 The enhanced 3270 user interface displays only data from V5.1.0, V5.2.0, V5.3.0, and V5.4.0 Storage agents. Data from prior versions is ignored in the interface.
OMEGAMON for z/OS V5.3.0 The product must be configured so that only V5.1.0, V5.1.1, or V5.3.0 agents are eligible to assume the sysplex proxy role. Otherwise, sysplex data is not available in the enhanced 3270 user interface until all OMEGAMON for z/OS monitoring agents are upgraded to version 5.3.0.

Incompatibility of V4.2.0 agents and native 64-bit monitoring servers

Tivoli Management Services on z/OS V6.3.0 and higher supports monitoring servers on native 64-bit Windows and xLinux systems. The IBM® Tivoli OMEGAMON V5.1.0 (or higher) family (including OMEGAMON XE for Db2 PE/PM V5.1.1 and OMEGAMON for Messaging for z/OS V7.1.0) supports the native 64-bit monitoring server. The OMEGAMON V4.2.0 family (including OMEGAMON XE for Db2 PE/PM V5.1.0 and OMEGAMON for Messaging for z/OS V7.0.1) supports only monitoring servers that run on 64-bit Windows and 64-bit Linux® platforms that use 32-bit compatibility mode with IBM Tivoli Monitoring V6.2.3.
If you are installing or upgrading a hub monitoring server on native 64-bit Windows and xLinux systems, the metaprobes that collect plex data for the following V4.2.0 family products are disabled until the products are upgraded to the V5.1.0 or above family versions:
  • OMEGAMON XE for Db2 Performance Expert V4.2.0, V5.1.0
  • OMEGAMON XE for Db2 Performance Monitoring V4.2.0, V5.1.0
  • OMEGAMON for z/OS V4.2.0
  • OMEGAMON for Messaging for z/OS V7.0.x

Globalization of interfaces

User interfaces for OMEGAMON V4.2.0 and later monitoring agents are globalized, with the following exceptions:

  • z/OS configuration tools, which are the Parameter Generator (PARMGEN) Workflow user interface and also Configuration Manager.
  • Installation program
  • OMEGAMON enhanced 3270 user interface
  • OMEGAMON II (CUA) interface
  • OMEGAMON (3270) interface

OMEGAMON V4.2.0 (or later) workspaces in the Tivoli Enterprise Portal are displayed in the specified language (for example, Spanish or Chinese).
