CEMT INQUIRE DSNAME
serialized by a backup manager such as
DFSMS/MVS before a data set backup copy can
be made.
Dynamic
The data set is accessed in RLS mode and is
eligible for BWO processing. Data set backup is
allowed while it is open for output, using a data
set backup manager such as DFSMShsm or
DFSMSdss.
2
Notapplic
The data set has not been opened by the CICS
region in which the command is issued, or the
data set is BDAM or a VSAM PATH. NOTAPPLIC
is also returned if the dataset has been opened in
RLS mode. The VSAM catalog should be referred
to get the BWO status.
FRlog(
value
)
displays the numeric journal identifier of the journal
being used to log the updates for forward recovery if this
data set is forward recoverable (FWDRECOVABLE). The
FRLOG value is undefined if the data set is not forward
recoverable. You can define a data set as forward
recoverable either in the ICF catalog or, if it is accessed
in non-RLS mode, in the file resource definition. This
option is meaningful only for data sets accessed in LSR
or NSR mode, and for which the forward recovery
attributes are obtained from the CICS file resource
definition.
For data sets accessed in RLS mode (if DFSMS 1.3 is
installed), or non-RLS mode data sets for which CICS
obtains the recovery attributes from the ICF catalog,
CICS displays a value of zero.
Availability
displays information indicating whether the data set is
currently flagged, in this CICS region, as available or
unavailable for use. The availability indicator is a local
flag that a CICS region maintains in a data set name
block (DSNB) for each data set. If the file is a BDAM
data set, no information is returned. The values are:
AVailable
The data set is available for use according to the
CICS data set name block. CICS can issue either
RLS or non-RLS open requests for this data set.
Note: Although a data set is available according
to information held by CICS, an open
request could still fail if the ICF catalog
indicates otherwise. This can occur, for
example, if data set recovery is pending or
actually in progress.
UNAvailable
The data set is marked by CICS as not available
for use. The CICS region is unable to open the
data set in either RLS or non-RLS mode.
AVAILABILITY can be reset by specifying AVAILABLE.
Lostlocks
displays whether there are any lost locks for this data
set. The possible values displayed are:
NOLostlocks
The data set has no lost locks.
REMLostlocks
The data set has lost locks, hence is unavailable,
but no recovery is required on this CICS. (The lost
locks belong to a another (remote) CICS region.)
RECOVERLocks
The data set has lost locks and therefore is
unavailable. This CICS system is performing
lost-locks recovery.
Retlocks
displays whether there are any retained record locks, as
a result of deferred recovery work by this CICS region,
for the specified data set.
RETAined
This CICS region has deferred recovery work
causing retained locks for the data set. One effect
of this is that, if the data set was last opened in
RLS mode, the locks are RLS locks and therefore
the data set cannot be opened in non-RLS mode.
Another effect is that any FILE definitions that
specify this data set cannot be changed to specify
a different data set.
If the data set is a BDAM data set, or a VSAM
data set accessed in non-RLS mode, the locks are
CICS record locks, otherwise they are RLS record
locks.
NORetained
This CICS region has no deferred recovery work
for the base data set, and therefore no retained
locks.
Note: Noretained can also mean that the CICS
region is currently processing deferred
recovery work. When the recovery work is
successfully completed, the value remains
as NORETAINED until more deferred work
is created. If the recovery work is not
successfully completed, the value reverts
to RETAINED.
