Fast Path log reduction

To reduce log volume you can use the LGNR parameter, which is specified on the DBC, FDR, and IMS startup procedures.

LGNR indicates the maximum number of DEDB buffer alterations that are held before the entire CI is logged.

Another way to reduce log volume is to designate the DEDB as nonrecoverable. No changes to the database are logged and no record of database updates is kept in the DBRC RECON data set.
