ZD - Default device control statements (SLU2 / 3270)
This reference topic describes how to add, modify, or delete the default SLU2 / 3270 device record.
The following keyword parameters can be specified:
- ASOT=
- This represents the automatic signoff time. The numeric value must be 0, or within the range of 10 - 1440.
- ALOT=
- This represents the automatic logoff time. The numeric value must be 0, or 10 - 1440.
- BYPSEC=
- Specify one of the following keyword options:
- YES
- When the user ID attempting /SIGN ON matches the Node name, IMS ETO Support sets the bypass the security flag in DFSSGNX0. The /SIGN ON completes without RACF® authentication.
- NO
- No special message handling is done for the /SIGN ON command.
- CONVREC=
- Specifies how IMS manages
conversational status.
- Y
- Specifies that if SRMDEF global/local is set, conversational status is recoverable.
- N
- Specifies that conversational status is not recoverable.
- (blank)
- If no option is specified, conversational recovery is managed based on the:
- Setting from the IMS ETO Support global options
- Setting in the DFSDCxxx PROCLIB member
- IMS system default
- DEVICE=
- Represents the device/model of the terminal. This should be the name of a statically SYSGENed terminal. IMS ETO Support uses the definition of this terminal to obtain the device type (MODEL=2) or the screen size (that is, for 3270-Ann devices).
- DFS3649=
- Specify one of the following options for processing the DFS3649 signon panel:
- DFS3649=IMS (for the IMS default panel)
- DFS3649=DFS2002 (to get message DFS2002)
- DFS3649=ETOS (to get IMS ETO Support provided signon
panel)
If DFS3649=ETOS is specified, you can also use the PASSSIZE= parameter to specify whether to use the IMS ETO Support password signon or the passphrase signon.
- DFS3649=DFSGMSG1 (for user DFSGMSG1 greetings exit)
- DFS3649=MOD (for user-supplied MFS mod name)
If DFS3649=MOD is specified, you must also specify MOD3649=<modname>.
- DFS3650=
- Specify the option for processing the DFS3650 session status panel:
- DFS3650=IMS (for the IMS default panel)
- DFS3650=DFS058 (to get message DFS058I)
- DFS3650=BLANK (to get a cleared panel)
- DFS3650=DFSGMSG1 (for user DFSGMSG1 greetings exit)
- DFS3650=MOD (for user-supplied MFS mod name)
If DFS3650=MOD is specified, you must also specify MOD3650=<modname>.
- DFS3650=DFS2002 (to get message DFS2002)
- DFS3650=TRX (to input a transaction)
If DFS3650=TRX is specified, you must also specify TRX3650=<trxname>.
- FPREC=
- Specifies how IMS manages
Fast Past status and message disposition.
- Y
- Specifies that if SRMDEF global/local is set, Fast Path status and messages are to be recoverable.
- N
- Specifies that Fast Path status and messages are not recoverable.
- (blank)
- If no option is specified, Fast Path status and message recovery
is managed based on the:
- Setting from the IMS ETO Support global options
- Setting in the DFSDCxxx PROCLIB member
- IMS system default
- LOGON=
- Specify one of these options:
- LOGON=ETOS (to use IMS ETO Support process)
- LOGON=DFSLGNX1 (to use DFSLGNX1 user exit)
- LOGON=AUTO (to use IMS ETO Support auto signon feature)
- MOD3649=
- Specify the 1- to 8-character alphanumeric MFS mod name. This
parameter is valid only if
DFS3649=MOD
is also specified. - MOD3650=
- Specify the 1- to 8-character alphanumeric MFS mod name. This
parameter is valid only if
DFS3650=MOD
is also specified. - MSGDEL=
- Represents the messages that are discarded by IMS for the specified terminal. The options are:
- MSGDEL=SYSINFO
- MSGDEL=NOTERM
- MSGDEL=NONIOPCB
- PASSSIZE=
- You can specify one of the following options if DFS3649=ETOS is also specified.
- PASSSIZE=P (to use IMS ETO Support passphrase signon panel)
- PASSSIZE=W (to use IMS ETO Support password signon panel)
- PASSSIZE= (to specify that the signon panel is to be determined by the MFSPPDEF parameter of the
DFSDCxxx PROCLIB member).
- MFSPPDEF=Y (to use IMS ETO Support passphrase signon panel)
- MFSPPDEF=N (to use IMS ETO Support password signon panel)
If this parameter is not specified and DFS3649=ETOS, the default is PASSSIZE=.
- QNAMING=
- The following options can be used to determine the USER/LTERM
structure names:
- QNAMING=IMS (for the IMS default)
- QNAMING=NUL (for NODE=USER=LTERM)
- QNAMING=USER (to specify a user from the table)
- QNAMING=SUFFIXED (to specify a suffixed user ID)
- QNAMING=DFSSGNX1 (for user-supplied DFSSGNX1 exit)
- QNAMING=APPEND@ (to specify user ID plus "@" character)
- QNAMING=IMSSUF (to specify IMSID-based user ID suffixing)
If
QNAMING=USER
is specified on the Device Default Options record, it merely sets the default action for ETO support processing. In order to actually obtain the USER/LTERM from the table, a user ID or Node record needs to be created defining the USER/LTERM names to be used. - RC3649A=
- Specifies whether IMS ETO Support will append error text to message DFS3649A if a signon failure
occurs when DFS3649=MOD is used.
- Y
- IMS ETO Support will append error text to message DFS3649A if a signon failure occurs when DFS3649=MOD is used.
- N
- IMS ETO Support will not append error text to message DFS3649A if a signon failure occurs when DFS3649=MOD is used.
- RESP=
- This represents the terminal response option. Valid specifications
are:
- RESP=NORESP
- RESP=FORCRESP
- RESP=TRANRESP
- SECURITY=
- Specify the name of the Security Group assigned to these devices. This option is used only if IMS ETO Support Security Table Lookup option is selected.
- SGNUSREC=
- Specifies whether a user ID record must be defined for a signon
to be successful.
- YES
- The IMS ETO Support user ID table is searched at signon time. The signon fails if there is not a matching entry in the table.
- NO
- Signon continues even if there is not a matching entry in the user ID table.
- SRMAFF=
- Specifies whether signon is allowed when an IMS Resource
Manager (RM) affinity exists.
- Y
- Signon is allowed even though an IMS Resource Manager (RM) affinity may exist.
- N
- Signon is not allowed if an IMS Resource Manager (RM) affinity exists.
- (blank)
- If no option is specified, signon with IMS Resource Manager
(RM) affinity is determined based on:
- Setting from the IMS ETO Support global options
- Setting in the DFSDCxxx PROCLIB member
- IMS system default
- SRMDEF=
- Specifies the status recovery mode.
- GLOBAL
- The IMS Resource Manager (RM) is to maintain terminal and user end-user status.
- LOCAL
- Terminal and user end-user status is to be maintained in local control blocks and log records.
- NONE
- Status is to be discarded at signoff/logoff/IMS restart.
- (blank)
- If no option is specified, status is maintained based on:
- Setting from the IMS ETO Support global options
- Setting in the DFSDCxxx PROCLIB member
- IMS system default
- TODCHECK=
- Specify one of the following keyword options:
- NONE
- Time-of-day checking is not done.
- LOGON
- Time-of-day checking is performed at logon.
- SIGNON
- Time-of-day checking is performed at signon.
- TRX3650=
- Specifies the name of the IMS transaction to schedule after a successful signon, instead of presenting the usual DFS3650I successful signon message. Specifying this option means that no values for options MOD3650= can be specified.
