The CICSplex Units of Work attributes report on transaction (UOW) activity.
CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS image has a unique name. This name is an alphanumeric string, with a maximum of 8 characters, and case-sensitive. CICS region names are always in uppercase characters.
CICS Version Indicates the version of CICS running in the address space. OMEGAMON XE for CICS on z/OS supports the following IBM software releases of CICS: 4.1.0, 5.1.0 (CICS Transaction Server 1.1); 5.2.0 (CICS Transaction Server 1.2); and 5.3.0 (CICS Transaction Server 1.3). Values are: 4.1.0, 5.1.0, 5.2.0, and 5.3.0.
CPU Time Indicates the amount of accumulated CPU time (in milliseconds) for this task. The value format is a positive integer, maximum 4 bytes.
Dispatch Time Indicates the amount of time (in milliseconds) that the tasks in the unit-of-work spent dispatched. The value format is a positive integer, maximum 4 bytes.
Exception Wait Indicates the amount of elapsed time (in milliseconds) that the task spent waiting for exceptions. The value format is a positive integer with a maximum of four bytes.
FEPI Suspend Indicates the amount of elapsed time (in milliseconds) that the task waited for all FEPI (front end programming interface) services. The value format is a positive integer with a maximum of four bytes. This data is available in CICS version 4 and above.
File Wait Indicates the amount of time (in milliseconds) that the task waited for file I/O to complete. The value format is a positive integer with a maximum of four bytes.
A high percentage of elapsed time spent waiting for file control requests can indicate inefficient local shared resource (LSR) specifications, too few strings, or lockout conditions.
First Dispatch Delay–Delay Indicates the amount of time (in milliseconds) that the task spent waiting for the first dispatch. The value format is a positive integer with a maximum of four bytes.
First Dispatch Delay–MXT Indicates the amount of elapsed time (in milliseconds) that the task waited for the first dispatch because the number of executing tasks reached the MAXTASK limit. The value format is a positive integer with a maximum of four bytes.
First Dispatch Delay–Other Indicates the amount of elapsed time (in milliseconds) that the task was delayed before the first dispatch because of conditions other than MAXTASK or CMXT. For example, this item can indicate a delay caused by CPU contention. The value format is a positive integer with a maximum of four bytes.
First Dispatch Delay–TCLASS Indicates the amount of elapsed time (in milliseconds) that the task was delayed before the first dispatch because the TCLASS limit was exceeded. The value format is a positive integer with a maximum of four bytes.
Journal Wait Indicates the amount of time (in milliseconds) the task waited for journal requests to complete. Journal waits occur as a task waits for Journal I/O to complete. The value format is a percentage in the range 0-100.
Explicit journal I/O includes any journal switching, buffering, and intervention that occurs between the time the journal requests were issued and the time they completed. Implicit journaling occurs when you define a file to CICS with the logging option. Updates to the file trigger journal operations, the elapsed-time percentage for which is included under File Control Percentage.
A high percentage of elapsed time spent waiting for journal I/O can indicate disk contention or reserves, elongated journal switching times, excessive journal buffer sizes, or inappropriate journal options.
KC ENQ Delay Indicates the amount of elapsed time (in milliseconds) that the task waited for a CICS task control enqueue. The value format is a positive integer with a maximum of four bytes.
LU6.1 I/O Wait Indicates the amount of elapsed time (in milliseconds) that the task waited for control at this end of an LU6.1 link. The value format is a positive integer with a maximum of four bytes.
LU6.2 I/O Wait Indicates the amount of elapsed time (in milliseconds) that the task waited for control at this end of an LU6.2 link. The value format is a positive integer with a maximum of four bytes.
MRO Wait Indicates the amount of time (in milliseconds) that the task waited for an MRO request to another region to complete. The value format is a positive integer with a maximum of four bytes.
A high percentage of time spent waiting for MRO operations can indicate problems in a connected CICS region that caused the originating transaction to wait for an extended period of time.
Number of Transactions Indicates the total number of tasks that executed in a CICS region on behalf of the unit-of-work. The value format is a positive integer with a maximum of four bytes.
Origin Node 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.
Overall Elapsed Time Indicates the total elapsed time (in milliseconds) between a task being attached and the current time for every transaction that makes up the unit-of-work. The value format is a positive integer with a maximum of four bytes.
Long-running transactions can produce performance records at regular intervals if you have specified the MNFREQ parameter with the SIT. If you have specified this parameter, this item can indicate the elapsed time from the start of the interval.
Redispatch Wait Indicates the amount of time (in milliseconds) that the task waited between a request completing and the task being redispatched by CICS. The value format is a positive integer with a maximum of four bytes.
This is the aggregate of the wait times between each event completion and user-task redispatch, but it does not include the time spent waiting for first dispatch. A high percentage of elapsed time spent waiting for redispatch Indicates that you can have looping transactions or that you can have reached the CMXT limit.
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 with a maximum of four characters, and is case-sensitive. z/OS System IDs are always in uppercase characters.
Task Number Indicates the number sequentially assigned by CICS to uniquely identify each task. The value format is an alphanumeric string with a maximum of four characters, and case-sensitive.
Task Status Indicates whether the task is running or complete. Values are:
Temporary Storage Wait Indicates the amount of time (in milliseconds) that the task waited for VSAM temporary storage I/O. The value format is a positive integer, maximum 4 bytes.
A high percentage of elapsed time spent waiting for this type of I/O Indicates inadequacies in the configuration of the temporary storage data set DFHTEMP. Typical causes include:
Terminal I/O Wait Indicates the amount of elapsed time (in milliseconds) that the task waited for user input from the terminal. The value format is a positive integer, maximum 4 bytes.
This item Indicates the amount of elapsed time (in milliseconds) that the task spent waiting for various operations to complete. This time does not include the first dispatch wait time.
Total RMI Elapsed Indicates the amount of elapsed time (in milliseconds) that the task spent in task-related user exits (TRUE). The value format is a positive integer, maximum 4 bytes. This includes the RMI (resource manager interface) calls to DBCTL and DB2.
Total RMI Suspend Indicates the amount of elapsed time (in milliseconds) that the task was suspended while within the task-related user exits (TRUE). The value format is a positive integer, maximum 4 bytes. This includes the RMI (resource manager interface) calls to DBCTL and DB2.
Total Wait Time Indicates the amount of elapsed time (in milliseconds) the tasks in the unit-of-work spent waiting for various operations to complete. The time does not include the first dispatch wait time. The value format is a positive integer with a maximum of four bytes.
Transaction ID Indicates the four-character identifier for the task. The value format is an alphanumeric string with a maximum four characters, and is case-sensitive. If OMEGAMON II for CICS umbrella transaction IDs are defined, the umbrella transaction ID is shown here.
Transient Data Wait Indicates the amount of time (in milliseconds) that the task waited for VSAM transient data I/O. The value format is a percentage in the range 0-100.
A high percentage of elapsed time spent waiting for this type of I/O Indicates inadequacies in the configuration of the transient data data set DFHINTRA. This can be caused by:
Unit of Work Identifier Indicates the CICS logical unit of work identifier. The value format is an alphanumeric string, maximum 52 characters.
