The CICSplex Region Overview attributes report on the internal resources of CICS regions. These resources include storage, files, queues, and enqueues.
AIDs Indicates the number of automatic initiate descriptors (AIDs) found on the AID chain within a given CICS region. The value format is a positive integer, maximum four characters. An AID is created when CICS is unable to start a task because a resource is not available. An accumulation of these descriptors can adversely affect CICS storage and CPU availability. An AID remains in CICS until the resource is available, CICS is shut down, or the AID is stopped.
Any Current WS Timeouts Indicates if any current Web Service requests had a fault associated with them.
Any Current WS Faults Indicates if any current Web Service requests had a timeout associated with them.
CICS Region Name Indicates the job name or the modify ID of the CICS region being monitored. Each CICS region in a z/OS operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters, and case-sensitive. CICS region names are always in uppercase characters.
CICS SYSIDNT Indicates the four character CICS system ID assigned to this CICS region. The value format is an alphanumeric string, maximum four characters, and case-sensitive. CICS system IDs are always in uppercase characters.
CICS TOD Clock Indicates the time of day clock setting in the CICS Common System Area (CSA). The time value is measured to two decimal places. The value can be entered in the hh:mm:ss.dd format, for example, 00:20:00.56 or as sssssss.dd, for example, 1200.56. If you are using variable substitution, the value in this example would display as 120056.
CICS TOD Updated Indicates whether the CICS time of day clock is being updated. When a task goes into a loop and the CICS task dispatcher is unable to regain control, the CICS time of day clock field in the Common System Area is not updated by task control. These are the values: Yes and No
CICS Version Indicates the version of CICS running in the region.
CPU Utilization Indicates the percentage of accumulated CPU time for the CICS region. This value is calculated at the beginning and end of a short elapsed-time interval. The difference between these two values is the amount of CPU consumed in the CICS region during that interval; this difference is then represented as a percentage of the elapsed-time interval. The value format is a percentage in the range 0-999.
Example:
Therefore percent of CPU used during time interval = 3/10 =30%
A low-to-zero value indicates the absence of a workload or non dispatch by z/OS. A high-to-100% (or greater) value indicates a heavy workload or a potential loop in either your application or CICS code. If the workload is running on multiple CPUs, the CPU utilization can exceed 100%.
Current VSAM Buffer Waits Indicates the total number of current VSAM buffer waits for the file definitions in the current CICS region. The value format is a positive integer, maximum four characters.
Current VSAM String Waits Indicates the total number of current VSAM string waits for the file definitions in the current CICS region. The value format is a positive integer, maximum four characters.
Enqueue Waits Indicates the number of CICS enqueues exclusively controlling a resource that tasks are also waiting for. The value format is a positive integer, maximum four characters. A large number signifies that too many tasks are competing for exclusive access to the same resources at the same time, which indicates a looping task, a deadlock situation, or poor response time from a task that holds an enqueued resource.
This value is stored in units of 1/100; therefore, when you open an event as attributes, you must interpret the performance index value of 1234 as 12.34. When you see the performance index in a view, however, a decimal point is inserted; therefore you interpret a value of 1234 as 12.34.
ICEs Indicates the number of interval control elements (ICEs) found on the ICE chain within a given CICS region. The value format is a positive integer, maximum four characters. An ICE is created whenever a time-dependent request for a CICS service is made. When the expiration time for the ICE is reached, the CICS service requested is initiated if the resources required for the service are available. If the requested service is task initiation, CICS creates an automatic initiate descriptor (AID) on ICE expiration. The AID either initiates the task or waits until required resources become available.
I/O Rate Indicates the rate at which I/O operations are being performed in a specified CICS region per second of elapsed time. It includes both application- and CICS-initiated I/O operations. The value format is a maximum of four characters.
Largest Contiguous Available LSQA Indicates the largest amount of contiguous local system queue area (LSQA) that is available. If LSQA accumulates to reach the top of the allocated private region, address space termination occurs. The value format is a positive integer, maximum four characters.
Largest Contiguous Available OSCOR Indicates the largest amount of contiguous free operating system core (OSCOR) that is available. If OSCOR is consumed to meet the IEALIMIT or expands to the bottom of the local system queue area (LSQA) address space termination occurs. The value format is a positive integer, maximum four characters.
Maximum Tasks Percent Indicates the total number of tasks within a CICS region, expressed as a percentage of the MXT limit. Attaching of new tasks within the CICS region stops when the maximum task limit reaches 100%. The value format is a percentage in the range 0-100.
Origin Node Is the combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.
When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.
Page Rate Indicates the number of page-in operations in the CICS region per CPU second. The paging rate is important because CICS transactions wait until a page-in resolves. The value format is a maximum of four characters.
Queued Remote Requests The CICS region's total number of queued allocation requests for MRO, ISC, and IP sessions. The value format is a positive integer of maximum four bytes.
Region Status Indicates CICS address space position. These are the values:
SOS Is the short-on-storage indicator. These are the values: YES and NO.
Storage Violations Indicates the number of storage violations that have occurred within the last hour. A storage violation occurs when CICS detects storage corruption for a task. The value format is a positive integer, with a maximum of four characters.
System ID Indicates the four character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum four characters, and case-sensitive. z/OS System IDs are always in uppercase characters.
Transaction Rate Indicates the average number of transactions executed in one minute of elapsed time. For example, if the statistics are collected every 10 minutes, and the total number of transactions during the last 10 minutes is 300, the average number of transactions per minute is 30. The value format is a positive integer of maximum two bytes.
VTAM ACB Open Indicates whether the VTAM Access Method Control Block (ACB) is open or closed. The VTAM ACB defines the interface between the application code (CICS) and VTAM routines enabling CICS to use the VTAM facilities. These are the values: Yes and No.
VTAM Applid Indicates the eight character name that specifies the VTAM applid of the CICS region. Each CICS region has a unique VTAM applid. The VTAM applids are always in uppercase characters. The value is an alphanumeric string, maximum eight characters and is case-sensitive.
VTAM Generic Applid Indicates the eight character name that specifies the generic VTAM applid of the CICS region. Each CICS region has a specific and a generic VTAM applid. Generic VTAM applids are always in uppercase characters. The value is an alphanumeric string, maximum eight characters and is case-sensitive.
Working Set Size Indicates the amount of central (both real and expanded) storage owned by the address space, including both address space and other storage, for example, dataspace, expressed as kilobytes. If the working set size value is high and central storage is constrained, considerable paging activity occurs, which degrades the response time. The value format is a positive integer, maximum four characters.
Worst Region Performance Index The worst performance index value for the CICS region, which is calculated using the response time for a service class and its' response time goal. This value is a useful indicator as to which CICS region’s response time might be starting to degrade. The number is presented as a percentage, accurate to two decimal places. A performance index greater than 1.00 indicates that the service class is no longer meeting its defined response time goal.
Worst Region Service Class Name The name of the service class whose transaction response times are performing the worst with respect to the user defined goals in the CICS region. The name is an alphanumeric string, with a maximum of eight characters, in length. The designation n/a is shown when there is no data to display.
XCF GROUP Indicates the eight character name of the XCF group where the CICS region belongs.
