VTAMLU Parameters

LINE Statement Parameters

TYPe is VTAMLU

Specifies the line type.

APPlication identification is vtam-application-id

Specifies the VTAM application identifier used by DC/UCF at runtime to open a VTAM access method control block (ACB) and prepare for communication with logical units.

Vtam-application-id must match the system identifier specified for the DC/UCF system in the VTAM system definition.

The APPLICATION IDENTIFICATION parameter is required to create an executable system.

CONnect

Specifies the line is treated as a connect-type line.

CONNECT is the default when you specify neither CONNECT nor NOCONNECT in the LINE statement.

NOConnect

Specifies the line is not treated as a connect-type line.

PASsword is vtam-password

Specifies the password used by DC/UCF to open a VTAM ACB.

Vtam-password must be the password specified for the DC/UCF application in the VTAM system definition.

RPL count is rpl-count

Specifies the number of request parameter list (RPL) storage areas to be used by the SNA/VTAM line driver to support all logged-on logical units. This number represents the maximum number of write I/O requests that can be handled concurrently by the SNA/VTAM line.

Rpl-count must be an integer in the range 1 through 32,767. The default is 5.

Typically, rpl-count should be lower than the expected number of logical units in the line. An insufficient RPL count value will result in degraded response time.

PTERM Statement Parameters

TYPe is

Specifies the device type for the physical terminal. Valid values are:

Note: For more information about SNA and LU 6.2 system generation considerations, see SNA and LU 6.2 Considerations.

ALReady VERified/NOT

For VTAMLU types LU and LU62, determines whether the requesting system has verified the user ID. The default is NOT.

ACQuire

Specifies the physical terminal is connected to the system automatically. The user does not have to log on through VTAM to access the system.

NOAcquire

Specifies the physical terminal is not connected to the system automatically. The user must log on through VTAM, supplying the DC/UCF system identifier.

NOACQUIRE is the default when you specify neither ACQUIRE nor NOACQUIRE in the PTERM statement.

CONtention is

Specifies whether a session bound using the physical terminal will be a bracket contention winner or loser.

Note: For LU 6.2 sessions, the multiple session service manager negotiates the numbers of contention winners and losers to be allowed with the remote LU. The CONTENTION parameter specification is used only for the initial count.

WINner

Specifies the session is a bracket contention winner. If a remote LU and the DC/UCF system attempt to allocate a conversation on the session at the same time, the DC/UCF system will have priority.

LOSer

Specifies the session is a bracket contention loser. If a remote LU and the DC/UCF system attempt to allocate a conversation on the session at the same time, the remote LU will have priority.

OFF

Specifies the session is either a bracket contention winner or a bracket contention loser.

OFF is the default when you omit the CONTENTION parameter from the PTERM statement.

HOLd

Specifies the physical terminal is not released when VTAM sends notification that another system is requesting a session with the logical unit.

NOHold

Specifies the physical terminal is released when VTAM sends notification that another system is requesting a session with the logical unit only if a conversation is not currently allocated to the session. If a conversion is allocated, the physical terminal is released after the conversation terminates.

NOHOLD is the default when you specify neither HOLD nor NOHOLD in the PTERM statement.

INFmh is

Specifies whether an input function management header (FMH) is expected as a prefix to a request/response unit (RU).

YES

Indicates that an FMH is expected. The FMH is not removed.

NO

Indicates the FMH is not expected. The FMH is automatically removed.

NO is the default when you omit the INFMH parameter from the PTERM statement.

LIMit on input is input-limit-size

Specifies the maximum amount of data, in bytes, the DC/UCF system is to buffer before the user requests that data.

Input-limit-size must be an integer in the range 0 through 32,767. The default, 0, directs the DC/UCF system not to limit the amount of data buffered.

MODeent is vtam-modeent-name

Identifies the mode table entry that contains the bind parameters to be used when initiating a session with the physical terminal.

Vtam-modeent-name must match the name specified by the LOGMODE parameter of the appropriate VTAM mode table entry.

Note: For real APPC support, vtam-modeent-name must match the name specified in the MODEENT parameter of a PTERM statement used to define a physical terminal for APPC.

You must name a mode table entry for logical unit type 6.2.

For more information about real APPC support, see Real APPC Support Considerations.

NOModeent

Specifies that VTAM is to use the default mode table entry for the logical unit.

NOMODEENT is the default when you specify neither MODEENT nor NOMODEENT in the PTERM statement.

NAMe is vtam-minor-node-name

Specifies the name of the VTAM node that will be associated with the terminal.

Vtam-minor-node-name must be the name of a VTAM minor node (logical unit) specified in the VTAM definition.

This parameter is required to create an executable system.

OUTfmh is

Specifies a default function management header (FMH) to be sent with all outbound transmissions for this logical unit.

'hex-fm-header-q'

Identifies the default FMH to be sent with all outbound transmissions.

Hex-fm-header-q is a 4- through 8-character hexadecimal literal enclosed in site-standard quotation marks that is included in every transmission.

NO

Indicates that no default FMH exists.

NO is the default when you omit the OUTFMH parameter from the PTERM statement.

RELease

Specifies the physical terminal is disconnected automatically whenever a conversation on the session terminates.

NORelease

Specifies the physical terminal is not disconnected automatically whenever a conversation on the session terminates; that is, the session will remain available for subsequent conversations. NORELEASE is recommended for greater efficiency.

NORELEASE is the default when you specify neither RELEASE nor NORELEASE in the PTERM statement.

NORELEASE should be specified for logical unit type 6.2.

SYNclevel is

For LU 6.2 sessions only, specifies the maximum level of synchronization to be allowed for a session that uses the physical terminal.

CONfirm

Directs the DC/UCF system to accept a bind with a synchronization level of CONFIRM or NONE.

SYNcpoint

Directs the DC/UCF system to accept a bind with a synchronization level of SYNCPOINT, CONFIRM, or NONE.

NONe

Directs the DC/UCF system not to accept a bind with a synchronization level of SYNCPOINT or CONFIRM.

OFF

Directs the DC/UCF system to accept the synchronization level specified in the bind parameters.

OFF is the default when you omit the SYNCLEVEL parameter from the PTERM statement.
