IMS system-level workspaces
OMEGAMON XE for IMS on z/OS default workspaces contain a variety
of charts that reflect the health of your monitored environment. The
following list includes descriptions of each of the default workspaces.
- The IMS Address Spaces workspace displays
detail address space information for the IMS Control Region and its
dependent regions. This workspace is comprised of three views:
- Paging and EXCP bar chart
- CPU Usage for TCB and SRB bar chart
- IMS Address Spaces table view
To improve integration among the applications and monitoring
agents that use the Tivoli Enterprise Portal to display data, a new
dynamic linking between workspaces is now available and is known as dynamic workspace linking. If a z/OS target node
is available, the IMS Address Spaces workspace offers links to four
OMEGAMON XE for z/OS workspaces:
- Address Space Bottlenecks Detail workspace
- Address Space Storage for Job workspace
- Address Space CPU Usage Details workspace
- Address Space Common Storage - Allocation Details workspace
Dynamic workspace linking is supported only between V4.1.0 (and
higher) workspaces. Predefined cross-product links to other
product workspaces are not displayed if the other product has not
been installed and configured.
- The IMS Bottleneck Analysis workspace allows
you to focus on workloads, rather than on resources. Its charts provide
summary-level short-term and long-term CPU use
percentages, transaction counts, and wait percentages by category.
In addition, the workspace displays (short term) wait counts by category.
- The IMS Bottleneck Analysis Details workspace,
available by link from the IMS Bottleneck Analysis workspace, displays
detail-level bottleneck analysis data. Its charts provide short-term
and long-term CPU use percentages and transaction counts. In
addition, the workspace provides a variety of data associated with
execution states.
- The IMS Coupling Facility Data Sharing Status workspace
shows detailed information about data sharing status, buffer counts,
queues, and structure size for the data sharing group you choose.
Up to 32 individual IMS systems in the IMS Sysplex attach to the Coupling
Facility through the OSAM and VSAM structures. These Coupling Facility
structures have information on the connections and the shared data.
Buffer status and connection information is found in the IMS control
blocks. Use the workspace to verify that Data Sharing is active, view
the number of buffers cached in the Coupling Facility and the number
for which data sharing is implemented, and determine the structure
size required.
- The IMS Coupling Facility Data Sharing OSAM Details workspace
displays a global view of the data sharing OSAM structures. The OSAM
cache structures are used to implement IMS database buffer invalidation.
When a data sharing buffer is changed by one of its applications,
IMS issues a buffer invalidate call to the Coupling Facility. IMS
is notified that its local copy of the data sharing buffer is not
valid and must be reacquired.
- The IMS DASD Logging workspace displays
DASD logging environment data.
- The IMS DBCTL Thread Summaries workspace
displays counts of thread states for each CCTL (CICS), the percentage
of active threads for each CCTL (thread ID), and summary information
for each CCTL. In addition, the UOW Rates graph indicates the input
and processed unit of work rate for each CICS system connected to
the IMS.
- The DBCTL Detailed Thread Activity workspace
displays the thread elapsed time, thread occupancy, and additional
details for each thread.
To improve integration among the
applications and monitoring agents that use the Tivoli Enterprise
Portal to display data, a new dynamic linking between workspaces is
now available and is known as dynamic workspace
linking. If a CICS target node is available, the DBCTL Detailed
Thread Activity workspace offers a link to the Transaction Analysis
workspace of OMEGAMON XE for CICS on z/OS.
Dynamic workspace
linking is supported only between V4.1.0 (and higher) workspaces.
Predefined cross-product links to other product workspaces
are not displayed if the other product has not been installed and
configured.

status information for dependent regions, including BMP checkpoint
counts, database calls, locks held count, and message inserts. The
workspace indicates the total DL/I calls and total service calls made
by a Fast Path Dependent Region application program during the processing
of a transaction. In addition, the workspace provides OTMA information,
if applicable, including the TMEMBER name, TPIPE name, commit mode,
synchronization level, and TPIPE status. This workspace is comprised
of two views:
- Dependent Region Counters bar chart

supports a link to the IMS Dependent Region Locking
Conflict in Classic workspace which displays lock conflicts for
the selected region in the Classic interface and a link to the IMS Console in Classic workspace which displays
OCMD or ICMD in the Classic interface configured to stop the current
transaction in the selected region.

Regions DL/I Statistics workspace displays counts for a variety
of DL/I message and DL/I database calls.
To improve integration
among the applications and monitoring agents that use the Tivoli Enterprise
Portal to display data, a new dynamic linking between workspaces is
now available and is known as dynamic workspace
linking. If a DB2 target node is available, the IMS Dependent
Regions workspace offers a link to the Threads workspace of OMEGAMON
XE for DB2 Performance Monitor/Expert on z/OS.
Dynamic
workspace linking is supported only between V4.1.0 (and higher) workspaces.

information about each active device in the system that this IMS system
is currently using. Exception cases are when Responding or Ready have
a value of No or when In Error Recovery has a value of Yes. Note that
this is a snapshot of device activity and will only show devices that
are active at the time of the error or for devices that are not ready,
not responding, or in error recovery at the time of the sample. This
workspace is comprised of a single view, the IMS Device
Activity table view.
