CEMT INQUIRE DB2ENTRY
DISabling
The DB2ENTRY is in the process of being
disabled. New transactions cannot access the
DB2ENTRY. Existing transactions using the
DB2ENTRY will be allowed to complete unless the
DB2ENTRY is being disabled with the FORCE
option.
PLAN
returns the name of the plan to be used for this
DB2ENTRY. If PLAN is returned, PLANEXITNAME is
blank.
PLANExitname
returns the name of the dynamic plan exit (if any) to be
used for this DB2ENTRY. If PLANEXITname is returned,
PLAN is blank.
PRIority
returns the priority of the thread subtasks for this
DB2ENTRY relative to the CICS main task (QR TCB).
The values are:
High subtasks attain a higher priority than the CICS
main task from which the subtask was generated.
Equal
subtasks have equal priority with the CICS main
task.
Low subtasks have a lower priority than the CICS main
task.
PROtectnum
returns the maximum number of protected threads
allowed for this DB2ENTRY.
PTheads
returns the current number of protected threads for this
DB2ENTRY. A protected thread is an inactive thread
available for reuse by a new transaction. If no
transaction has reused the thread by the time it has
been processed by 2 purge cycles, the thread is
terminated.
THREADS
returns the current number of threads active for this
DB2ENTRY.
THREADLimit
returns the current maximum number of threads for this
DB2ENTRY that the CICS DB2 attachment allows active
before requests are made to wait, overflow to the pool,
or are rejected (see THREADWait).
THREADWait
returns whether or not transactions should wait for a
DB2ENTRY thread be abended, or overflow to the pool
if the number of active DB2ENTRY threads reach the
Threadlimit number. The values are:
TWait
If all threads are busy, a transaction waits until
one becomes available.
NOTwait
If any threads are busy, a transaction is
terminated with an abend code AD2P.
TPOOL
If all threads are busy, a transaction is diverted to
use a pool thread. If the pool is also busy, and
NOTWAIT has been specified for the
THREADWAIT parameter on the DB2CONN, the
transaction is terminated with an abend code
AD3T.
