In an MRO environment, you can maintain MUF-level processing options for remote systems using the DBEC command with the SYSID option to specify all connected CICS systems or a specific CICS system. Requests for information on MUF resources are issued with the DBEC transaction followed by the INQUIRE operand. The options enable you to invoke a display of all MUFs or a limited set of MUFs for a remote CICS system or all connected CICS systems.
You can alter certain fields on the panel. Any alterations made, take effect immediately and are valid only during the life of the CICS session.
The following is an example of a DBCSID macro. DBCSID macros are appended to the DBCVTPR macro, each defining a particular CA Datacom/DB MUF. The values for the bold-faced parameters in this example are displayed on the MUF-level inquiry.
DBCSID SIDNAME=DBSIDPR,USERS=3,CONNECT=PLT,EOJ_OK=DISCONNECT
Invoke the inquiry as shown following to display the status of CA Datacom/DB MUFs or to display the statistics for MUFs.
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.

(Required) Specify a transaction ID valid with Enhanced commands used to monitor MUFs. Select the transaction ID for which you are authorized. Leave a space between the transaction ID and the command.
(Required) Requests a scrollable display of MUFs (INQ and I are valid abbreviations) for the remote CICS system or in the case of all CICS systems, in the order in which the connections are defined to this CICS.
(Required) Specifies the inquiry is to invoke the MUF-level display. The value within the parentheses identifies the number of the MUF relative to the order of the DBCSID macros appended to the DBCVTPR macro, if multiple MUFs are defined.
Specifies that you want to display only the MUF with the specific 2-digit number nn.
Alternately, instead of using the nn number to specify only a specific MUF, you can use the wildcard symbol ? (a question mark) to accept any digit 0 through 9 for one (or both) of the two digits of the number.
(Required) Specifies the inquiry is to invoke the MUF-level display. The value within the parentheses identifies the name of the MUF specified in the DBCSID macros appended to the DBCVTPR macro, if multiple MUFs are defined. The MSIDNAME(xxxxxxxx) qualifier should not be used with the MUF(nn) qualifier. If it is used with the MUF(nn) qualifier then the MUF(nn) qualifier takes precedence and the MSIDNAME(xxxxxxxx) qualifier is ignored
Specifies that only the MUF with the specific SIDNAME in the DBCSID macro coded with the DBCVTPR is displayed.
Alternately, you can use the wildcard symbol * (an asterisk) to display all MUFs or characters succeeded by the asterisk to display all MUFs beginning with a range of SIDNAMEs by beginning values as specified in the DBCSID macros appended to the DBCVTPR macro.
(Optional) Specifies a MUF-level statistics display for the remote CICS system or optionally all remote CICS systems as opposed to a MUF-level display for that or those CICS systems. From this display, a line command is available to reset the statistics for a selected MUF when the DBEC transaction ID is used and the user is allowed to perform updates.
(Optional) Limits the inquiry to MUFs of designated status, or how defined for opening. A limiter can be specified with the STATS option to invoke the MUF-level statistics display that is further limited by this option. The following are the values for designating limiters of each type:
MUFs explicitly disconnected through a DBEC command. (DIS is a valid abbreviation.)
MUFs with a disconnect in progress, where the status is set to disconnected at the completion of the current read or update and URT closes.
MUFs that are currently connected. (CON is a valid abbreviation.)
MUFs with a connect in progress, where URT opens are invoked at the completion of the current connect.
MUFs defined as AUTO or DEFER that have not been connected by a program call or a DBEC transaction.
MUFs defined to be connected when required by a program.
MUFs defined to be connected only by an explicit DBEC command. (DEF is a valid abbreviation.)
MUFs connected at CA Datacom CICS Services startup, that is to say those not defined for AUTO or DEFER.
