Purpose

Using the MODIFY DEFAULTS command, you can change the current value of the DLOGMOD operand of a definition statement for an LU, application program, or cross-domain resource without deactivating the entire major node.

Using the MODIFY DEFAULTS command, you can also change the delay timer for disconnection of a switched PU.

When VTAM® receives the MODIFY DEFAULTS command, it overlays the existing value for the specified operand with the new value.

Note:

If you use the MODIFY DEFAULTS command to change the DLOGMOD specification, be aware that later use of a VARY ACT,UPDATE=ALL command for dynamic reconfiguration can undo the effects of the MODIFY DEFAULTS command. This is because the DLOGMOD value in the definition file overrides the value that was established with the MODIFY DEFAULTS command. Even if no DLOGMOD is coded in the definition file, VTAM assumes a null value for DLOGMOD and the null value overrides the MODIFY DEFAULTS value. To prevent the new DLOGMOD specification from being deleted unintentionally, code the DLOGMOD definition statement with the required value.
You can use the to perform the same function as this command.

Operands

procname

The procedure name for the command. If procname in the START command was specified as startname.ident, where startname is the VTAM start procedure and ident is the optional identifier, either startname.ident or ident can be specified for procname.

If procname in the START command was startname, startname must be specified for procname.

DISCNTIM=time_period

Specifies the amount of time that VTAM delays deactivation of the SSCP-PU session when there are no outstanding LU-LU session requests.

You can specify the time in seconds (S). Specify the number of seconds as an integer in the range 5–65535.

DISCNTIM is valid only for PU types 2 and 2.1 that have DISCNT=DELAY specified on the PU definition statement.

DLOGMOD=logon_mode_name

Specifies the new value for the logon mode. If DLOGMOD is specified with a null value (left blank), the predefined DLOGMOD value is deleted.

Note: If DLOGMOD is specified with an unknown logon mode, a warning message is issued indicating that it is unknown and the change is accepted.

ID=resource_name

Specifies the name of the resource to which the command applies. The name can be a network-qualified name. If the name specified on the ID operand is network-qualified, this name is considered to be the real name of the resource.

Tip: If you are specifying a model resource (APPL or CDRSC), you can use wildcard characters in the name you specify. The use of wildcard characters on the ID operand does not depend on the value of the DSPLYWLD start option.

Note: If the resource name is a cross-network CDRSC which is defined with NQNMODE=NQNAME (either by definition statement or start option), be sure to use its network-qualified name on this command.
