Detail line descriptions

CICS transaction detail line

This is the first-level detail line. Each line shows information about a CICS® transaction for which measurement data was recorded.

Under Heading This is Displayed
Name The CICS transaction code.
NTxns The number of executions of the transaction.
Description If this is a recognized CICS transaction, a functional description.
Error The margin of error for the mean values calculated by using the number of executions of the transaction as the sample size.
Execution The mean time, in seconds, a CPU was actively executing for the transaction.
Suspend The mean time, in seconds, CICS had suspended execution of the transaction.
Delay The mean time, in seconds, execution of the transaction was delayed. This is a fourth-level detail line shown directly under the CICS transaction detail line. This line represents a CICS resource type or a wait type. The complete list of resource types is documented in the CICS Transaction Server for z/OS® Problem Determination Guide

The most common wait types include:

CICS
The CICS region was busy processing other transactions and could not dispatch this transaction.
MVSWait
The entire region was in a wait for an MVS™ service.
MVSBusy
The MVS system was busy and did not dispatch the CICS region.
CICSSusp
The transaction has been suspended by CICS while waiting on a resource.
Service The mean service time for the transaction. This includes execution, suspend and delay time.

CICS program or system services detail line

This is a second-level detail line shown directly under the CICS transaction detail line. This line represents a CICS program (usually an application) that was in control during execution of the transaction. The third-level lines shown under this item can be either CICS command lines, SQL Request lines, DL/I Request lines or Module lines.

If no CICS application program was dispatched, "CICS" is shown under the Name heading and "System Services" under the Description heading.

Under Heading This is Displayed
Name The module name of the CICS program. If lines grouped under this line are CICS command lines, DB2® SQL, or IMS™ DLI calls, this field is displayed in red. For Module lines grouped under this line, the field is turquoise. "CICS" is displayed here if no application program was in control.
NTxns If lines grouped under this line are CICS command lines, this displays "EXEC CICS". If lines grouped under this line are SQL request lines, this displays "EXEC SQL". If lines grouped under this line are DL/I request lines, this displays "EXEC DLI". Otherwise, if the program name is a recognized CICS module name (a DFH* name), a functional description is shown, and "CICS Program" is displayed if it is not recognized; indicating this is likely an application program. "System Services" is displayed if no application program was in control.
Description If this is a recognized CICS transaction, a functional description.
Execution The mean time, in seconds, CPU execution was observed while transaction control was under the CICS program identified in the Name column.
Suspend The mean time, in seconds, CICS had suspended execution of the transaction while transaction control was under the CICS program identified in the Name column.
Delay The mean time, in seconds, execution of the transaction was delayed. This is a fourth-level detail line shown directly under the CICS transaction detail line. This line represents a CICS resource type or a wait type. The complete list of resource types is documented in the CICS Transaction Server for z/OS Problem Determination Guide

The most common wait types include:

CICS
The CICS region was busy processing other transactions and could not dispatch this transaction.
MVSWait
The entire region was in a wait for an MVS service.
MVSBusy
The MVS system was busy and did not dispatch the CICS region.
CICSSusp
The transaction has been suspended by CICS while waiting on a resource.
Service The mean service time for the transaction control was under the CICS program identified in the Name column. This includes execution, suspend and delay time.
