Overview of NDM
The following table describes the NDM data sets.
NDM data sets
Data set | Description | Attributes | Values |
---|---|---|---|
BMCLOADLIB | BMCLOADLIB contains the update or fix for the Reorg Online solution code. Its contents are copied by NDM to either BMCLIBA or BMCLIBB. BMCLOADLIB, BMCLIBA, and BMCLIBB should have the same BLKSIZE. | DSORG | Partitioned |
DSNTYPE | PDS | ||
RECFM | U | ||
LRECL | 0 | ||
BLKSIZE | > or = 18432 Default 18432 | ||
BMCLIBA/B | BMCLIBA and BMCLIBB contain BMCLOADLIB members. When one of these libraries is active (in use by the online product), the contents of BMCLOADLIB are copied to the other, or inactive, library for use in the next online change run. Prior to running online, you should APF authorize these data sets to the MVS system. BMCLOADLIB, BMCLIBA, and BMCLIBB should have the same BLKSIZE. | DSORG | Partitioned |
DSNTYPE | PDS | ||
RECFM | U | ||
LRECL | 0 | ||
BLKSIZE | > = 18432 Default 18432 | ||
BMCSTAT | BMCSTAT contains information to indicate which of the following suffixed data sets Online Reorg must use at initialization time. BMCSTAT must be the ddname for the BMCLIBA and BMCLIBB data sets. | DSORG | PS |
DSNTYPE | Sequential | ||
RECFM | FB | ||
LRECL | 80 | ||
BLKSIZE | Any multiple of 80 |
