CEMT INQUIRE UOWLINK
CEMT INQUIRE UOWLINK
Function: Retrieve information about connections involved
in units of work.
Description: INQUIRE UOWLINK returns information
about a connection involved in a unit of work. The connection
can be to a remote system, or to a task-related user exit. If it
is to a remote system, INQUIRE UOWLINK displays the
netname of the connection, its sysid, and whether it is the
coordinator or subordinate. If it is to a task-related user exit,
INQUIRE UOWLINK displays the exit’s entry name and
qualifier.
Input: Press the Clear key to clear the screen. There are
two ways of commencing this transaction:
Type CEMT INQUIRE UOWLINK (the minimum abbreviation
is CEMT I UOWL ). You get a display that lists all the
current UOW-links.
Type CEMT INQUIRE UOWLINK ( CEMT I UOWL ) followed by
as many of the other attributes as are necessary to limit
the range of information that you require. So, for
example, if you enter
cemt i uowl rmi , the resulting
display will show you details only of UOW-links to
external resource managers.

Note: There are blank fields on the screen where a value
does not apply or is ‘negative’; that is, the value
begins with ‘No’. To modify these fields, locate them
by tabbing (they appear in the same sequence as in
the expanded format), and overtype with input valid
for that field. You may find it more convenient to use
the expanded format when setting one of these
values, (negating is easier because you are
overtyping a displayed field with its negative causing
the result to become non-displayed).
If you place the cursor against a specific entry in the list and
press ENTER, CICS displays an expanded format as shown
in Figure 136.

Displayed fields
LInk( value)
displays, for a TYPE value of CONNECTION, the
8-character netname of the remote system. For a TYPE
value of RMI, LINK displays the entry name of the
task-related user exit. For a TYPE value of CFTABLE,
LINK displays the 8–character name of the coupling
facility data table pool.
NEtuowid( value)
displays a 27-character string containing the
network-wide LU6.2 name for the UOW.
Note: Nondisplayable characters appear as periods.
You can use PF2 on the expanded panel to see
the value in hexadecimal.
Protocol
displays the communication protocol used by the
connection. The values are:
Irc Inter-Region Communication. This is an MRO
connection.
