CEMT PERFORM DUMP|SNAP CEMT PERFORM ENDAFFINITY
CEMT PERFORM DUMP|SNAP
Function: Obtain a CICS system dump.
Description: To get a CICS system to dump and continue
processing, you can use either the CEMT PERFORM DUMP
command or the CEMT PERFORM SNAP command. Both
commands produce a “snapshot” of the CICS system.
The use of CEMT PERFORM DUMP or CEMT PERFORM
SNAP prevents all other tasks from running. Consequently,
terminal operators may experience delays in response.
Syntax
─ ──CEMT Perform ──┬ ┬─DUmp─ ──┬ ┬────────────── ─
└┘─SNap─ └ ┘──Title(value)
Options
DUmp
specifies that a system dump is to be produced.
SNap
specifies that CICS is to issue the MVS SDUMP macro
to produce an SDUMP (system dump) of the CICS
region.
Title(
value
)
specifies a title of up to 32 characters; it is added at the
beginning of the dump. If your title includes spaces, you
must enclose the whole title within single quotation
marks ('').
CEMT PERFORM ENDAFFINITY
Function: End an affinity owned by CICS.
Description: Where CICS is a member of a VTAM
generic resource group, PERFORM ENDAFFINITY instructs
VTAM to end an affinity owned by CICS, whether or not the
connection has been deleted. If the connection has not been
deleted, it must be out of service and have no recovery
information outstanding—that is, its RECOVSTATUS (as
displayed by CEMT INQUIRE/SET CONNECTION) must be
NORECOVDATA.
Generic resources and affinities are described in the
CICS
Intercommunication Guide
.
Syntax
─ ──CEMT Perform Endaffinity ──NETName(value) ──
─ ──┬ ┬────────────── ─
└┘──NETId(value)
Options
NETId(
value
)
specifies the 8-character name by which the network
containing the connected LU is known to VTAM.
If you do not specify a NETID, CICS takes the value
from the installed connection, if it exists. If you do not
specify a NETID and the connection does not exist, the
command fails.
NETName(
value
)
specifies the 8-character APPLID of the connected LU. If
the connected LU is a member of a generic resource,
you must specify its member name, not the generic
resource name.
Note: There is no facility in VTAM for inquiring on affinities,
so CICS has no certain knowledge that an affinity
exists for a given connection. Whenever there is a
possibility that an affinity has been created that you
must end explicitly, CICS issues message
DFHZC0177. This message gives the NETNAME and
NETID to be passed to VTAM.
If a request to end an affinity is rejected by VTAM
because no such affinity exists, CICS issues
message DFHZC0181. This may mean either that
you entered the NETNAME or NETID incorrectly, or
that you (or CICS) was wrong in supposing that an
affinity existed.
