MODIFY IMR command

Abbreviations

Purpose

The MODIFY IMR (intensive mode recording) command enables you to request that an NCP provide detailed information concerning temporary line errors or other hardware error conditions for a station on an SDLC link. IMR can be specified for a peripheral physical unit of an NCP or for a cross-subarea link station within an NCP. For more information about intensive mode recording, such as the reason for using it and information about where the output is recorded, see z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures.

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.

ID

Specifies the name of the resource for which IMR data is to be recorded.

ID=link_station_name

Records IMR data for a link station.

ID=pu_name

Records IMR data for a physical unit.

OPTION

Specifies whether IMR should be started or stopped for the named link station or physical unit.

OPTION=ACT

Specifies that IMR should be started for the named link station or physical unit.

OPTION=INACT

Specifies that ongoing intensive mode recording should be stopped, and that the NCP is not to generate any more IMR records for the named link station or physical unit.

RECLIM=number_of_errors

Specifies the maximum number of temporary errors that are recorded for the named link station or physical unit. When this limit is reached (or IMR is canceled with OPTION=INACT), the NCP reverts to sending only permanent error records to VTAM. Any decimal integer 1–65535 can be specified. The default is 10. RECLIM is not applicable if OPT=INACT is specified.
