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 A functional description (if the transaction is a recognized CICS transaction).
Error The margin of error based on a sample population of the number of executions of the transaction.
Execution The total time, in seconds, that a CPU was actively executing for the transaction.
Suspend The total time, in seconds, that CICS had suspended execution of the transaction.
Delay The total time, in seconds, that execution of the transaction was delayed.

Transaction execution can be delayed for one of the following reasons:

  • CICS dispatch delay
  • MVS™ dispatch delay
  • MVS WAIT
Service The total service time for the transaction. This includes execution, suspend, and delay time.

CICS region applid detail line

This is the second-level detail line shown directly under the CICS transaction detail line. This line represents the VTAM applid of the CICS region sampled. If a transaction shows more than 1 region applid, then activity was measured in multiple regions for that transaction.

Under Heading This is Displayed
Name The CICS region applid. This is the VTAM applid of the region where the samples were taken.
NTxns The number of executions of the transaction.
Description "Region Applid"
Execution The total time, in seconds, that a CPU was actively executing for the transaction in the region.
Suspend The total time, in seconds, that CICS had suspended execution of the transaction in the region.
Delay The total time, in seconds, that execution of the transaction was delayed in the region.

Transaction execution can be delayed for one of the following reasons:

  • CICS dispatch delay
  • MVS dispatch delay
  • MVS WAIT
Service The total service time for the transaction in the region. This includes execution, suspend, and delay time.

CICS program or system services detail line

This is a third-level detail line shown directly under the CICS region applid detail line. This line represents a CICS program (usually an application) that was in control during execution of the transaction. The fourth-level lines shown under this item can be either CICS command lines, SQL Request lines, DLI 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, 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.
Description If lines grouped under this line are CICS command lines, the description displays "EXEC CICS." If lines grouped under this line are SQL request lines, the description displays "EXEC SQL." If lines grouped under this line are DLI request lines, the description 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 the CICS module name is not recognized; indicating this is likely an application program. "System Services" is displayed if no application program was in control.
Execution The total time, in seconds, that CPU execution was observed while transaction control was under the CICS program identified in the Name column.
Suspend The total time, in seconds, that CICS had suspended execution of the transaction while transaction control was under the CICS program identified in the Name column.
Delay The total time, in seconds, that execution of the transaction was delayed while transaction control was under the CICS program identified in the Name column.

Transaction execution can be delayed for one of the following reasons:

  • CICS dispatch delay
  • MVS dispatch delay
  • MVS WAIT
Service The total service time for the transaction during which control was under the CICS program identified in the Name column. Service time includes execution, suspend, and delay time.

CICS command detail line

These lines are displayed under a CICS Program detail line. Each one represents a CICS command issued by the program identified in the name field of the CICS Program line under which these lines are grouped.

Under Heading This is Displayed
Name The hexadecimal offset in the identified CICS program of the return address of the EXEC CICS command. This hexadecimal offset appears in +xxxx format. If the CSECT containing the EXEC CICS is not the same name as the module identified in the CICS Program line above, this field contains the CSECT name. In this case, the offset is shown in the description field. This field is always displayed in red.
Description The CICS command description. If, as noted above, the CSECT name containing the EXEC CICS is different from the module name, the CICS command description is preceded by the hexadecimal offset of the command from the start of the CSECT.
Execution The total time, in seconds, that CPU execution was observed while the CICS command was being processed.
Suspend The total time, in seconds, that CICS had suspended execution of the transaction while the CICS command was being processed.
Delay The total time, in seconds, that execution of the transaction was delayed while the CICS command was being processed.

Transaction execution can be delayed for one of the following reasons:

  • CICS dispatch delay
  • MVS dispatch delay
Service The total service time for the transaction during which the CICS command was being processed. This includes execution, suspend, and delay time.

SQL request detail line

These lines are displayed under a CICS program detail line. Each line represents an SQL request issued by the program identified in the name field of the CICS program line under which these lines are grouped.

Under Heading This is Displayed
Name The hexadecimal offset in the identified CICS program of the return address of the EXEC SQL command. This is in +xxxx format. This field is always displayed in red.
Description The SQL request function - SELECT, FETCH, UPDATE, etc.
Execution The total time, in seconds, that CPU execution was observed while the SQL request was being processed.
Suspend The total time, in seconds, that CICS had suspended execution of the transaction while the SQL request was being processed.
Delay The total time, in seconds, that execution of the transaction was delayed while the SQL request was being processed.

Transaction execution can be delayed for one of the following reasons:

  • CICS dispatch delay
  • MVS dispatch delay
Service The total service time for the transaction during which the SQL request was being processed. This includes execution, suspend and delay time.

DLI request detail line

These lines are displayed under a CICS Program detail line. Each line represents an IMS™ DLI request issued by the program identified in the name field of the CICS Program line under which these lines are grouped.

Under Heading This is Displayed
Name The hexadecimal offset in the identified CICS program of the return address of the EXEC DLI command. This is in +xxxx format. This field is always displayed in red.
Description The DLI function code followed by the PCB name.
