This workspace provides an overview of all the sysplexes in your enterprise. You can use it to view at a glance information about the sysplexes in your network and select a specific sysplex to investigate in more detail. The Sysplex Enterprise Overview workspace is the default workspace for the z/OS Systems Navigator entry.
The Sysplex Enterprise Overview workspace presents seven views, one for every area of information provided by Tivoli OMEGAMON XE on z/OS, as well as information about enterprise-wide global enqueues.
Sysplexes Global Enqueue
The Sysplexes Global Enqueue table view provides information on all global enqueues conflicts in a sysplex. In terms of business goals, this view enables you to expedite the release of a particular resource.
From this table you can link to a workspace providing details for a selected workspace, such as a list of contenders for resources, as well as the amount of time a user has been waiting for a resource. See Global Enqueue Data for Sysplex workspace.
Sysplexes GRS
The Sysplexes GRS (Global Resource Serialization) table provides information about the condition of ring connections, the traffic on the rings, and the rings relevant to specific z/OS systems and their activities and response times. You can use the view to understand when GRS response time is elongating or if there are disruptions on the ring. The information is important for analyzing enqueue delays in workloads.
From this view, you can link to a workspace displaying GRS ring systems data for a selected sysplex. See GRS Ring Systems Data for Sysplex workspace.
Enterprise Global Enqueue
The Enterprise Global Enqueue table view displays detailed information on all global enqueues in the enterprise. It contains data on all enqueue conflicts in the enterprise, including conflicts between sysplexes in those configurations in which enqueue management spans two or more sysplexes. In such configurations, each z/OS image can be defined as belonging to an Enqplex.
An Enqplex is a group of z/OS images under common enqueue management. A resource in one Enqplex is distinct from a resource having the same name in another Enqplex. Systems (that is, z/OS images) that do not define the Enqplex to which they belong are assigned to the *DEFAULT Enqplex and are assumed to share resources and enqueue management. Two or more sysplexes having the same Enqplex name share qname/rname resources.
From this workspace, you can link to a workspace displaying global enqueue data for a selected sysplex. See Enterprise Enqueue and Reserve workspace.
Crypto Coprocessor Overview
The Crypto Coprocessor Overview table displays the name and status of Integrated Cryptographic Service Facility (ICSF) subsystems on all monitored z/OS images and the status of cryptographic services in those subsystems.
From this workspace, you can link to a workspace displaying summary information about Integrated Cryptographic Service Facility (ICSF) subsystems on each z/OS image, service call performance information by system, and top users by system. See Cross-system Cryptographic Coprocessor Overview workspace.
Sysplexes Workloads
The Sysplexes Workloads table displays information that enables you to determine whether your workloads are meeting their performance goals. Through detailed views, you are able to examine how a particular business workload is performing without regard to the number of address spaces or z/OS images involved in processing the work. You are also able to identify specific address spaces and systems hindering the performance of a workload.
From this table, you can link to workspaces that provide information about the services classes, service definitions, resource groups, and report classes associated with a selected sysplex. See Service Classes Data for Sysplex workspace, Service Definition Data for Sysplex workspace, Resource Groups Data for Sysplex workspace, Report Classes Data for Sysplex workspace.
Sysplexes Coupling Facility
The Sysplexes Coupling Facility view displays coupling facility information for all your monitored sysplexes. The coupling facility acts as a shared storage device, allowing address spaces on separate z/OS images to share data buffers and messages. This table provides an overview of coupling facility resources, which allows you to ensure that connections are working, that an acceptable number of structures are defined within the coupling facility, that CPU and storage are used properly, and that I/O rates are maximized.
From this table you can link to workspaces displaying data for the coupling facility policy, structures, and systems associated with a selected sysplex. See Coupling Facility Systems Data for Sysplex workspace, Coupling Facility Structures Data for Sysplex workspace, Coupling Facility Policy Data for Sysplex workspace.
Sysplex Shared DASD
The Sysplexes Shared DASD table enables you to view information regarding DASD shared by systems in a monitored sysplex.
From this view, you can link to a workspace which provides detailed information about the DASD groups shared by a selected sysplex. See Shared DASD Groups Data for Sysplex workspace.
Sysplexes XCF
The Sysplexes XCF view provides information on cross-system coupling facilities (XCF) use by all the sysplexes. XCF allows address spaces on different systems of a sysplex to communicate with one another in order to process work cooperatively. You can use the Sysplexes XCF view and related workspaces to perform the following tasks:
This report makes it easy to uncover problems that may require a path redefinition or adjustments to hardware (such as the failure of a link).
From this table, you can link to workspaces that display information about the XCF groups, systems, and paths associated with a selected sysplex. See XCF Systems Data for Sysplex workspace, XCF Groups Data for Sysplex workspace, and XCF Paths Data for Sysplex workspace.
