Action to perform with DBEX:
Select and display the return code summary for that MUF.
Select and begin browse display at the URT level.
Select and begin browse display of active tasks for that MUF.
Select and begin browse display of the concurrent users summary for that MUF.
Identifies the CICS system to which this display line refers. *LOC means local CICS or TOR.
Identifies sequence number of the MUF.
Indicates the CONNECT status of the MUF:
Not yet connected by a program call, PLT, or a DBEC transaction.
Explicitly disconnected with a DBEC P,DISCONNECT.
Disconnect requested by DBEC P,DISCONNECT command, but not yet disconnected pending completion of a read in progress, URT closes, or a transaction having exclusive control.
Connected by CA Datacom CICS Services but no transaction to disconnect it has been issued.
Connect requested by DBEC P,CONNECT command, but not yet connected pending completion of the request in progress in the MUF.
(WHEN) Indicates when CA Datacom CICS Services connects the MUF:
(PLT) Specifies the MUF is to connect by CA Datacom CICS Services at startup time.
(AUTO) Specifies the MUF is automatically connected by CA Datacom CICS Services when an application request or URT open needs this MUF.
(DEFER) Specifies the MUF can only be connected with an explicit DBEC command.
The E (EOJ_OK) value represents CA Datacom CICS Services participation in an EOJ being issued for the default MUF. A value of No indicates that CA Datacom CICS Services does not participate in the EOJ of MUF. This means that MUF cannot EOJ until the MUF is disconnected in CA Datacom CICS Services. The value of Disconnect or Immediate determines the CA Datacom CICS Services action when notified of a MUF EOJ. If these two values are specified and there is no request activity within a specific time interval in CICS for this MUF, MUF severs the connection. The MUF startup option of X_EOJ_OK_S_DELAY determines this interval. This feature is not supported in CA Datacom/DB Version 12.0.
Number of tasks allocated to this MUF for processing requests.
The SIDNAME specified on the DBCSID macro in the DBCVTPR or the default SIDNAME of DBSI*DPR if no DBCSID macro has been specified in the DBCVTPR macro.
Note: The status of any MUF displayed in this manner is current as of the time of the last request processed by that MUF. For example, if the last request processed by a MUF was 90 seconds ago, a DBEC I,MUF (or DBEX I,MUF) request displays the status of that MUF as it was 90 seconds ago.
Identifies the job name of the active MUF.
Identifies the release level of the active MUF.
This field displays the MUF name if the SIDNAME module is assembled with a name that is specified by the MUFNAME= that matches the MUF name specified in the MUF startup option. Otherwise, this field displays the number of the SVC and SVC sub-ID associated with this MUF as defined in the SIDNAME module.
Specifies one of the following:
The last connect request for this MUF failed for the reason indicated by CA Datacom/DB return code nn and internal return code yyy.
The last disconnect request for this MUF failed for the reason indicated by CA Datacom/DB return code nn and internal return code yyy.
For CICS regions defined in CICS by CONNECTION and SESSION CSD definitions, see the Message Reference Guide for a description of the messages that are displayed if that the inquiry cannot retrieve the requested MUF-level display information.
From this display, if you key an E in the action field of the first MUF row, the resulting display shows the return code summary for that MUF.

Identifies the CICS system to which this display line refers. *LOC means local CICS or TOR.
The ID of the MUF accessed by the current event, consisting of two numbers nn, where nn can be 01 through 99.
The Task Control Block sequence number which identifies the thread used by the current event.
The CICS transaction ID associated with the listed task.
The ID of the terminal which initiated the listed command, or ???? if no terminal was attached to the issue of the command.
Time of day when the task last issued a CA Datacom/DB request.
CICS Task number.
AWAITING DB RESPONSE—A request passed control to the MUF and has not yet returned control to CA Datacom CICS Services.
ABENDING—The task has an abend condition or the MUF detected an abnormal condition.
COMMIT IN PROCESS—The task is terminating and CA Datacom CICS Services is performing final task cleanup.
EXCLUSIVE CONTROL—The task has acquired exclusive control by reading a record for update and the TCB is dedicated to this task until it finishes.
COMMIT FAIL—The task is terminating, but the CA Datacom CICS Services final cleanup for the task has failed.
DWE IN PROCESS—The task is terminating.
SYNCPOINT IN PROCESS—The task is currently in CICS SYNCPOINT processing.
DTB IN PROCESS—The task ended abnormally and is terminating with dynamic transaction backout.

A sequence number for a user invoking the reserving of transactions or physically waiting on a read event, where asterisks following the sequence number carry the following meaning:
The values shown 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, this means that 3 requests were counted at a time when there were six concurrent users issuing requests.
Indicates the percentage of time that concurrent requests are being issued by the number listed in the USERS column. That is, 6 users are attempting requests concurrently about 13 percent of the time. In the display example, USERS 006 percentage data 13.04 was computed by dividing 3 (frequency of USERS: 006) by 23 (frequency of USERS: 001, which was serviced 100 percent of the time).
Users concurrently invoking reserving transactions or physically waiting on a read event for the selected MUF indicated by its sequence number in the DBCSID macros of the DBVTPR and the SIDNAME specified in the respective DBCSID macro.
Note: After statistics are captured over a longer period of time, the graphical display under Concurrent Users for Selected MUF becomes more meaningful.
