Notes:

SAVERSCV is meaningful only if NODETYPE is also used.

Specifies whether or not Route Selection Control Vectors (RSCVs) for future sessions are to be saved for display purposes following the completion of session activation. SAVERSCV also specifies whether RSCV storage for existing sessions should be freed immediately. By default, these RSCVs are not saved. If YES or SAWDATA is specified, the D NET, SESSIONS, PATHINFO=YES, SID= command can then be used to display the saved RSCVs for the particular session specified.

SAVERSCV covers any session RSCVs reported by a DLUR node because of DLURSAW=YES having been specified as a start option, but SAVERSCV does not cover any RTP information (including HPR RSCVs) reported by a DLUR node.

You can change the value of SAVERSCV with the MODIFY VTAMOPTS command while VTAM® is running.

Note: The secondary values, FREE and KEEP, have no effect at VTAM START time.

SAVERSCV=(,FREE): Specifies that RSCV storage for existing sessions is to be freed immediately. The primary value currently in effect (YES,NO, or SAWDATA) remains unchanged.
SAVERSCV=NO: Specifies that RSCVs for future sessions are not saved following the completion of session activation. By default, RSCVs for existing sessions will remain.
SAVERSCV=(NO,FREE): Specifies that RSCV storage for future sessions are to be freed following session activation, and that RSCV storage for existing sessions is to be freed immediately.
SAVERSCV=(NO,KEEP): Specifies that RSCV storage for future sessions are to be freed following session activation, but that RSCV storage for existing sessions will remain.
SAVERSCV=YES: Specifies that RSCVs for future sessions are to be saved following the completion of session activation.
SAVERSCV=SAWDATA: Specifies that only the RSCVs associated with any sessions matching the PLU/SLU combination in the SAW data filter table are saved. This option can be used whether or not NetView® is running on the given VTAM. If a new SAW data filter table is activated and if SAVERSCV=SAWDATA, the SAW data filter table will control which RSCVs are reported to NLDM and will impact the saving and reporting of RSCVs associated with future sessions. The reporting of RSCVs for sessions that are already active will be governed by the previous SAW data filter table.

Note: Changing the SAVERSCV option from YES to NO, or from SAWDATA to NO, is intended to indicate that RSCV storage for future sessions is not to be saved.
