Job DSNTIJCB
Job DSNTIJCB supports the DSNJCNVT stand-alone utility for converting the BSDS records to support 10-byte RBA and LRSN fields.
DSNTIJCB consists of the following job steps:
- DSNTDEF
- Activates IDCAMS to define new BSDS data sets with CLUSTER, DATA, and INDEX components under the temporary names prefix.BSDS01.NEW and prefix.BSDS02.NEW.
- DSNTCNVT
- Activates DSNJCNVT to read records from the existing BSDS, converts them to support the extended RBA and LRSN format, and writes them into the prefix.BSDS01.NEW and prefix.BSDS02.NEW data sets.
- DSNTRENO
- Renames the existing BSDS data sets to backup names, prefix.BSDS01.OLDFMT and prefix.BSDS02.OLDFMT.
- DSNTRENN
- Renames prefix.BSDS01.NEW and prefix.BSDS02.NEW to prefix.BSDS01 and prefix.BSDS02.
No job step can run unless all preceding job steps complete with return code 0.
When the installation CLIST customizes DSNTIJCB, it substitutes the BSDS names that are specified in fields COPY 1 NAME and COPY 2 NAME on installation panel DSNTIPH for prefix.BSDS01 and prefix.BSDS02. The fields allow each name to support names up to 30 bytes in length, so no special handling is needed to rename the existing data sets.
