Address Space TCBS attributes

The Address Space TCBS attributes provide information about the tasks active in an address space. Among the attributes included in the group are the mother, daughter, and sister relationships, the dispatching priority, and the CPU seconds used by each task.

Abnormal Dump Abnormal termination in progress for the task. Y=Yes, N=No.

Abnormal Wait The task is a subtask of a failing task and has been placed in an abnormal wait state for clean-up. Y=Yes, N=No.

APF Status Indicates the APF authorization status of the task. Y= Authorized, N=Unauthorized.

ASID Address Space ID in Hexadecimal. The address space ID is a unique number assigned to an address space when it is created. It is used by MVS to differentiate between address spaces.

Attached Nondispatchable The task is temporarily nondispatchable because it was attached with the operand DISP=NO. Y=Yes, N=No.

Attention The task is nondispatchable because the stage 3 exit effector must run to synchronize an attention interrupt. Y=Yes, N=No.

Cancelled The task is set nondispatchable by the initiator to prevent job step execution so that cancel processing can be done. Y=Yes, N=No.

Completion Code The completion code of the task.

CPU Seconds The number of CPU seconds used by the task displayed in .01 seconds.

Dispatching Priority Number Specifies the signed number (-255 to +255) to be algebraically added to the current dispatching priority of the mother task. The resulting number is the dispatching priority of the child, i.e., this task.

DAR Permanent The task is permanently nondispatchable due to the damage assessment routine (DAR). Y=Yes, N=No.

DAR Temporary The task is temporarily nondispatchable due to the damage assessment routine (DAR). Y=Yes, N=No.

Daughter TCB Address The address of the daughter TCB for this TCB.

Daughter TCB Name The program associated with the first RB of the daughter TCB.

DDR Allocation The task is allocating a device and dynamic device reconfiguration has set the task nondispatchable. Y=Yes, N=No.

DSS The task has been set nondispatchable by the dynamic support system (DSS). Y=Yes, N=No.

ECB Wait The top RB for the task is waiting on an ECB. Y=Yes, N=No.

Environmental Recording System environmental recording in progress. Y=Yes, N=No.

Excessive Paging The task is nondispatchable due to an excessive paging rate. Y=Yes, N=No.

FLIH Processing The task is waiting for an SRB to be scheduled to do PIE/PICA processing (First Level Interrupt Handler). Y=Yes, N=No.

Input Wait The task is nondispatchable because it is waiting for input. Y=Yes, N=No.

Initiator Waiting The task is nondispatchable because the initiator is waiting for the region. Y=Yes, N=No.

Job Name Address Space name (JOB/STC name, TSO User ID).

JOBSTEP TCB Address The address of the jobstep TCB for this TCB.

JOBSTEP TCB Name The program associated with the first RB of the jobstep TCB.

Key The storage protect key of the TCB. Valid range is 0 - 15.

Limit Priority Number Specifies the number (0 to +255) to be subtracted from the current limit priority of the mother task. The resulting number is the limit priority of the child, i.e., this task.

Managed System Managed system name where this data is collected. It has the format: <plexname>:<smfid>:MVSSYS. <plexname> is the sysplex this LPAR resides in. <smfid> is the system's SMF identifier.

Mother TCB Address The address of the mother TCB for this TCB.

Mother TCB Name The program associated with the first RB of the mother TCB.

No RQEs I/O Request Queue Elements are exhausted. Y=Yes, N=No.

Output Wait The task is nondispatchable because it is waiting for output. Y=Yes, N=No.

Parallel TMP The task is nondispatchable because an authorized TSO request is active on another task. Y=Yes, N=No.

RMS Permanent The task is permanently nondispatchable due to recovery management support and system error recovery. Y=Yes, N=No.

RMS Temporary The task is temporarily nondispatchable due to recovery management support and system error recovery. Y=Yes, N=No.

Set Up Abterm The task is temporarily nondispatchable while it is being set up for abnormal termination. Y=Yes, N=No.

Sister TCB Address The address of the sister TCB for this TCB.

Sister TCB Name The program associated with the first RB of the sister TCB.

SMF Exit Running There is an SMF exit running. Y=Yes, N=No.

SRBs Stopped The task is nondispatchable because SRB's have been stopped as a result of a STATUS STOP,SRB command. Y=Yes, N=No.

Status Indicating if the task is dispatchable or non-dispatchable. If the task is non-dispatchable, then at least one of the non-dispatchable reasons should be indicated. N=Non-dispatchable, D=Dispatchable.

Step Must Complete A different task is in step must complete status. Y=Yes, N=No.

SLIP PER The task is nondispatchable so that the request block PSW PER bit can be altered by SLIP/PER. Y=Yes, N=No.

Status Stop The task is nondispatchable because a STATUS STOP has been issued against it. Y=Yes, N=No.

Subtask Abending The task is abending and nondispatchable because it has a jobstep subtask that is abending. Y=Yes, N=No.

Swapping Out The task is nondispatchable because it is in the process of being swapped out. Y=Yes, N=No.

System Must Complete A different task is in system must complete status. Y=Yes, N=No.

Task Dumping The task is nondispatchable because SVC dump is executing for another task. Y=Yes, N=No.

Task Terminated The task has terminated. Y=Yes, N=No.

Task Terminating The task is terminating and an open for a dump data set or an abend close is in progress. Y=Yes, N=No.

TCAM Waiting The task is being delayed until a TCAM I/O appendage or SVC routine has completed execution. Y=Yes, N=No.

TCB Address The address of the TCB.

TCB Description A description of the TCB based upon a table of well-known program names executing in the first RB.

TCB Name TCB name. The name of the program on the first RB under the TCB.

Wait for Resources The task is waiting for resources. Y=Yes, N=No.
