CICSplex Unit-of-work Link Details attribute group

The CICSplex Unit-of-work Link Details attribute group displays information about a connection involved in a unit of work. The connection can be to a remote system, to a task-related user exit, or to a CFDT server.

Connection Type Is the type of connection associated with the unit-of-work link. Values are:

CFTABLE
A connection to a CFDT server.
CONNECTION
A connection defined in a CONNECTION resource definition.
OTS
An OTS link.
RMI
A connection to an external resource manager using the resource manager interface (RMI).

Connected System ID Is the ID of the connected CICS region.

CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS image has a unique name. This name is an alphanumeric string, with a maximum of 8 characters, and case-sensitive. CICS region names are always in uppercase characters.

Host ID Is the TCP/IP host name, or the TCP/IP address for the participant in the OTS transaction. This can be a string containing the dotted decimal TCP/IP address, used to refer to the participant in the OTS transaction. This is useful for identifying the participant, especially when problems occur. This is a 255-character data-area. Strings of fewer than 255 characters are padded with blanks. Note that the UOW and the participant can belong to the same CORBA server.

Link token Is the identifier token for the current Unit-of-work Link.

Link ID Is the netname of the remote system for CONNECTION types, or the entry name of the task-related user exit for RMI types, or the name of the coupling facility data table pool for CFTABLE type, or blanks for an IIOP type.

Network Unit-of-work identifier Is the network-wide LU62 ID of the current unit of work.

Origin Node Is the combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.

When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.

Protocol Indicates the communication protocol used by the connection. Values are:

APPC
Advanced Program to Program Communication.
IRC
Interregion Communication. This is an MRO connection.
LU61
LUTYPE 6.1.
IIOP
OTS.
RRMS
The UOW is coordinated by RRS/MVS.
N/A
This is a connection of type CFTABLE or RMI.

Resync. status Indicates the resynchronization status of the connection. Values are:

COLD
The connection has been cold started by the partner system. The partner can no longer coordinate any in-doubt conditions for this system; nor can this system pass to the partner any decisions remembered for it.
NOTAPPLIC
The connection was not created using recovery protocols. It could be an RMI, an APPC single-session, an APPC synclevel 1 connection, or a CFDT server.
OK
The connection is operating normally. If there has been a failure of the partner system, the partner has been restarted and the connection is able to resynchronize the associated UOW.
STARTING
The connection is being acquired, but the exchange lognames process has not yet completed.
UNAVAILABLE
The connection is not currently acquired.
UNCONNECTED
There is no associated connection.

RMI Qualifier Is the RMI qualifier of the task-related user exit. It is the 8-character entry qualifier of the task-related user exit. For a TYPE of CONNECTION, CFTABLE or IIOP, RMIQFY returns blanks.

Role Indicates the role for the connection. Values are:

COORDINATOR
This connection is to the syncpoint coordinator for the UOW.
SUBORDINATE
This connection is to a syncpoint that is subordinate to the UOW.
UNKNOWN
The syncpoint role of this connection cannot be determined.

System ID Indicates the four-character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum 4 characters, and case-sensitive. z/OS System IDs are always in uppercase characters.

Unit-of-work identifier Is the identifier of the current unit-of-work.

Unit-of-recovery ID Is the RRMS unit-of-recovery indicator.
