The IMS TranNameView panel displays.

If you have specified one or more transaction codes in the IMS Monitoring Criteria panel (see "Monitoring criteria for IMS" on page 83), the IMS TranNameView panel will display one line with the transaction code other. This transaction code represents all other transactions that are intercepted but DO NOT appear in the list of specified IMS Monitoring Criteria transactions.

You can see additional fields by scrolling to the right.

The fields in this panel are described next.

CTL Region

Name of the MVS main storage region that contains the IMS control program.

IFP/BMP/MPP Region

Name of the MVS main storage region that contains the IMS message processing program.

IMS ID

Name of the IMS system.

Region Active

Percentage of time that the IMS Region was active during the monitor session.

Region Idle

Percentage of time that the IMS Region was idle during the monitor session.

Region Total

Total time that the IMS Region was operating during the monitor session.

Average Elapsed

Average elapsed time (in seconds) for all transactions detected.

Tran Code

IMS Transaction name; the panel is sorted on this field.

PSB Name

Name of the PSB to which the transaction is defined.

A PSB can be associated with multiple transactions. In a Message Processing Region (MPR) the PSBname must be the same as the Program name.

Tran Count

Number of times this transaction was executed during the monitor session..

Total Elapsed Time

Total time (HH:MM:SS.NNNNNN) that the transaction was executing.

Avg Elapsed Time

Average time (HH:MM:SS.NNNNNN) that the transaction was executing.

DL/I Call Interface

IMS data manipulation language, which is a common high-level interface between a user application and IMS.

Visual

Depicts the elapsed time of the transaction compared to all transactions.

CPU Time (CPU sec)

Total amount of CPU time required to process all occurrences of the transaction (in CPU seconds). You need to scroll to the right to see this field.

CPU Avg. (CPU sec)

Average amount of CPU time required to process a single occurence of the transaction (in CPU seconds). You need to scroll to the right to see this field.

Region Idle and Region Total ONLY include the period of time between the first and last DLI call intercepted in the IMS message region being monitored. Therefore Region Total can be equal or less than the total monitor session elapsed time.

Enter the PSBname primary command on the COMMAND line and press Enter to see the activity and delays for all the detected IMS calls by PSBNAME, PCB #, call type, and segment.

The IMS Statements panel displays.

Summarize the activity and delays for all the detected IMS calls from the transactions by database by entering the DBDname primary command on the COMMAND line of the IMS TranNameView panel and pressing Enter.

Display the IMS Statements panel for a specific transaction by entering the Statements line command (S) next to a transaction from the IMS TranNameView panel. The IMS Statements panel displays for that transaction.
