The CICSplex MVS TCB RESOURCE Details attributes report addresses, storage, tasks, and transactions running on a CICS TCB.
CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters, and case-sensitive. CICS region names are always in uppercase characters.
CICS Task Number Is the CICS task number (1-99999) of the current task running on this TCB, if any.
CICS TCB Specifies whether this is a CICS-owned TCB or not. CICS-owned TCBs are the CICS jobstep TCB and those that were attached by CICS system code. Non-CICS TCBs are those that were attached by other products in the CICS address space.
CPU Time Is the accumulated CPU time (in seconds accurate to thousandths of a second) for this TCB, taken from TCB field TCBTTIME. The valid format is a floating-point number, accurate to three decimal places.
CPU per cent Is the percentage of the CPU time for all current TCBs of this type (CICS or non-CICS) that this TCB has taken. Note that only currently attached TCBs are listed. There can have been others that have now terminated.
Daughter TCB Is the address of this TCB's daughter TCB, that is, one that it attached.
Mother TCB Is the address of this TCB's mother TCB, that is, the one that attached it.
Origin Node 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.
Private Storage Below 16M Is the amount of private storage below the 16 megabyte line currently allocated to this TCB. This consists of whole pages allocated to the TCB by z/OS. Each page will typically contain bytes that are not in-use (have not been returned in response to a GETMAIN request) and are only available to GETMAIN requests from this TCB.

Sister TCB Is the address of this TCB's sister TCB, that is, the next one attached by its mother.
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.
Task Status Is the run status of the CICS task on this TCB. These are the possible values: DISPATCHABLE, RUNNING or SUSPENDED.
TCB Address Is the address of the z/OS Task Control Block (TCB).
TCB Name Is the name of TCB such as QR, RO, DFHTRTCB for CICS-owned TCBs otherwise the value 'non-cics' is used for TCBs running in the CICS address space but not owned by CICS.
Transaction Identifier Is the transaction ID of the CICS task currently running on this TCB.
