z/OS Degradation Delay Analysis

Degradation delay metrics will appear only for the top 20 worst 'Job Name_ASID' as determined by the delay percent value. If a job is no longer within the top 20, the metrics will not be reported; the metrics will be absent and the job name will change to gray.

The metrics for each degradation delay appear under the folder: z/OS Metrics|Degradation Delay Analysis|<Job Name>_<ASID>.

These metrics are listed in the order they appear on the Degradation Delay Analysis Typeview table and so are not in alphabetical order.

Job Name

Specifies the name of the job. The value of this metric forms the first part of the degradation delay's folder name.

ASID

Specifies the hexadecimal address space ID. This metric will not appear if it has no value. This becomes the second underscore separated segment of the degradation delay's folder name when it exists.

Reason

Specifies the reason for the delay. The value of this metric determines how the ‘Detail’ metric should be interpreted. This table lists the possible reasons and the meaning of the details provided.

Reason	Explanation of the delay	The 'Detail' metric provides
CPU	CPU time was not available	The top five users upon which the CPU resources were waiting. It is possible for a multi-TCB ASIC to be waiting on itself.
DEVICE	Device(s) were not available	The top six devices upon which the job was waiting.
STORAGE	Storage was not available	No additional details are available.
JES	JES resources were not available	JES2 Code Explanation: 0001 - Processing TSO OUTPUT command request 0002 - Waiting for JES2 to cancel a job 0003 - Waiting for job status information from JES2 0012 - Waiting for JES2 to purge a SYSOUT file 0013 Waiting for JES2 to restart a job JES3 Code Explanation: 0023 - Dynamically allocating data set to JES3 0026 - Changing DDNAME of device or data set 0027 - Changing data set use from SHR to OLD 0132 - Allocate or deallocate spool data set
HSM	HSM resources were not available	Code Explanation 03 - A data set is being recalled from auxiliary storage 05 - A data set is being recovered 06 - A data set is being migrated 07 - A data set is being backed up 08 - A control data set record is being read, or a JES3 C/I locate is being done 12 - A data set is being deleted
XCF	XCF resources were not available	No additional details are available.
MOUNT	A device was waiting to be mounted	VOLSER waiting to be mounted.
MESSAGE	An operator reply was pending	The operator reply number.
ENQUEUE	An enqueue conflict exists	The QNAME:RNAME of the enqueue.

CPU: Specifies the percent of time the job was waiting for CPU resources during the interval.
Device: Specifies the percent of time the job was waiting for a device during the interval.
Storage: Specifies the percent of time the job was waiting for storage during the interval.
Subsystem: Specifies the percent of time the job was waiting for a subsystem request during the interval.
Operator: Specifies the percent of time the job was waiting for an operator response during the interval.
Enqueue: Specifies the percent of time the job was waiting for access to an enqueue during the interval.
Delay Percent: Specifies the percent of time the job was waiting for resources during the interval. On the typeview Degradation Delay Analysis table this field will highlight yellow to indicate warning if it is 50 percent or greater but less than 75 percent. It will highlight red to indicate problem if the percent is 75 percent or more. The typeview threshold values for the warning and problem status modes are not modifiable.
Detail: See the detail supplied in the table for the Reason metric.

The typeview on the z/OS Metrics folder tab Degradation Delay Analysis displays all the individual degradation delays. The Degradation Delay Analysis displays all the individual delays in a single table. The columns appear in the general order as the CA SYSVIEW delays display; with the different that ASID will be displayed to the immediate right of the Job Name and several other fields are not displayed. The rows are sorted on the Delay Percent column, so that the most delayed items appear at the top and the highest status is first. The Delay Percent column will be color coded as to severity with Red indicating greater than 75% delay and yellow indicating greater than 50% delay. This typeview is also available by selecting the z/OS Metrics|Degradation Delay Analysis folder in the tree and tab Overview in the right hand panel.
