Display Example: DBEC I,MUF(??)

When you key an E in the action field of the first MUF row of the MUF-level display, the return code summary for that MUF displays.

MUF(01) DATABASE RETURN CODE SUMMARY MSIDNAME(DBDVMS): The MUF and MSIDNAME values reflect the MUF from which this inquiry was selected on the MUF display screen.

From the previously shown screen, PF3 returns you to the MUF-level display where you can select another display, and PF1 refreshes the current display. From the MUF-level display, you can then key a T in the action field of a MUF row. The resulting display is the active task summary for that MUF.

Field Descriptions

A: Specifies that there is no available action.
SYS: Identifies the CICS system to which this display line refers. *LOC means local CICS or TOR.
MUF: Identifies the ID of the MUF accessed by the current event, consisting of two numbers nn, where nn can be 01 through 99.

TIME: Time of day when the task first used this Task Control Block.
REQS: Number of CA Datacom/DB requests issued by the referenced task using the referenced TCB.
URT1-URT9: First through ninth URT used for exclusive control in this task.

From the screen:

PF1 refreshes the data of this screen
PF10 returns to the first screen of active task data
PF3 returns you to the MUF-level display where you can select another display.

From the MUF-level display, you can then key a U in the action field of a MUF row. The resulting display is the task usage summary for that MUF.

Field Descriptions

USERS

Specifies a sequence number for a user invoking reserving transactions or physically waiting on a read event. Asterisks following the sequence number carry the following meaning:

The highest number without an asterisk identifies the value assigned to the USERS= parameter, for example, 3 in the display example.
The 12 extra USERS (021**-032**) beyond the allocated USERS represent how many more USERS you could allocate to have better distribution of TCB usage.

FREQUENCY

The values under the FREQUENCY heading denote the total number of requests at the time a request arrives for service. CA Datacom CICS Services requires n threads (for USERS: nnn) to service the request without waiting for thread availability. For example, for USERS 006 in the example, means that 685 requests were counted at a time when there were six concurrent users issuing requests.

PERCENTAGE

Indicates the percentage of time that concurrent requests are issued by the number listed in the USERS column. That is, 6 users are attempting requests concurrently about 97 percent of the time. In the display example, USERS 006 percentage data 96.88 was computed by dividing 685 (frequency of USERS: 006) by 707 (frequency of USERS: 001, which was serviced 100 percent of the time).

CONCURRENT USERS FOR MUF(nn) MISDNAME(xxxxxxxxx)

Users concurrently invoking reserving transactions or physically waiting on a read event. The MUF and MSIDNAME values reflect the MUF from which this inquiry was selected on the MUF display screen.

Note: After statistics are captured over a longer time period, the graphical display under "Concurrent Users" becomes more meaningful.
