Deactivating the VIT

To deactivate specific VIT options, use the corresponding commands that are listed in Table 1.

Table 1. Deactivating the VIT
To deactivate these user-selected options:	Specify:
Specific options	MODIFY NOTRACE,TYPE=VTAM,OPTION=`options`
VIT group options	MODIFY NOTRACE,TYPE=VTAM,OPTION=group_option All the individual VIT options encompassed by each group option specified by the group_option value are deactivated. Internal tracing continues for the default options that cannot be deactivated. Tracing also continues for exception records. For example, issuing a MODIFY NOTRACE,TYPE=VTAM,OPTION=EEOPTS command results in the deactivation of these options: CIA, CIO, HPR, MSG, NRM, PIU, PSS, SSCP, SMS, and TCP. But CIO, MSG, NRM, PIU, and SSCP option data continues to be traced internally (PSS and SMS option data is not traced internally).
Subtrace options	MODIFY NOTRACE,TYPE=VTAM,SUBTRACE=subtrace_option, OPTION=vit_option or MODIFY NOTRACE,TYPE=VTAM,SUBTRACE=subtrace_option, OPTION=(..,vit_option,..) The subtrace option specified by the subtrace_option value is deactivated. The option specified by the vit_option value must relate to the subtrace_option value in one of the following ways: If you specify SUBTRACE=ARBP, the vit_option value must be HPR or one of the group options that include HPR as an individual option equivalent: DLUROPTS, EEOPTS, HPDTOPTS, HPROPTS, QDIOOPTS, or XCFOPTS. If you specify SUBTRACE=DIO, the vit_option value must be CIA or one of the group options that include CIA as an individual option equivalent: EEOPTS, HPDTOPTS, HPROPTS, QDIOOPTS, TCPOPTS, or XCFOPTS. If you specify SUBTRACE=TGVC or SUBTRACE=TREE, the vit_option value must be SSCP or one of the group options (all of which include SSCP as an individual option equivalent): APIOPTS, APPCOPTS, CPCPOPTS, CSMOPTS, DLUROPTS, EEOPTS, HPDTOPTS, HPROPTS, LCSOPTS, QDIOOPTS, STDOPTS, TCPOPTS, or XCFOPTS.
Internal only	MODIFY NOTRACE,TYPE=VTAM,OPTION=END or MODIFY NOTRACE,TYPE=VTAM,OPTION=END,MODE=INT The internal trace table is reallocated to 4 megabytes for the default options. MODIFY NOTRACE,TYPE=VTAM,OPTION=ALL,MODE=INT The existing internal trace table is used for the default options. MODIFY NOTRACE,TYPE=VTAM,MODE=INT External tracing record is stopped.
External only	MODIFY NOTRACE,TYPE=VTAM,OPTION=END,MODE=EXT or MODIFY NOTRACE,TYPE=VTAM,OPTION=ALL,MODE=EXT MODIFY NOTRACE,TYPE=VTAM,MODE=EXT External trace recording is stopped and all 8 K buffers are freed.
Both internal and external	MODIFY NOTRACE,TYPE=VTAM,OPTION=ALL The existing internal trace table is used for the default options.
Notes: Exceptions and default options continue to be recorded internally. If you attempt to stop the VIT using MODIFY NOTRACE, OPTION=END, and the VIT does not stop, specify MODIFY NOTRACE,OPTION=FORCE to stop the VIT.
