Converting Uncontrolled Disk Datasets
Description Existing uncontrolled disk datasets can be placed under BIM-EPIC
control. Any existing dataset can be controlled as long as all the
associated extents reside in a single-disk pool that is defined to
BIM-EPIC. You can convert a disk dataset to catalog control or Start
Track 1 control.
Converting to a
Disk Dataset
Procedure
To convert a disk dataset to catalog control:
Converting to
Start Track 1
Procedure
To convert a disk dataset to Start Track 1:
Step Action
1 Catalog the dataset name as a work file. You can use Online
Manager and specify WRK on the Define an EDD panel or you
can use TSIDMNT CATALOG function and specify
WRK=YES parameter.
2 Renumber the dataset extents using the TSIDVUT RENUM
function. (BIM-EPIC-controlled disk files must begin with
extent sequence number 1.)
3 Change the dataset VTOC expiration date to permanent using
TSIDVUT RETAIN function. Catalog-controlled disk files are
scratched according to the retention criteria specified in the
EDD, not the VTOC expiration date.
4 Add the version to the DSN catalog using Online Manager or
TSIDMNT ADD functions. Be sure to specify the block size, if
it is known.
5 Update the file type from WRK to GEN using the Online
Manager or the TSIDMNT UPDATE function, if generation
retention for the dataset has been specified.This must be done
after the step 4 has been successfully completed.
Step Action
1 Renumber the dataset extents using TSIDVUT RENUM.
BIM-EPIC-controlled disk files must begin with extent sequence
number 1.
2 If necessary, change the dataset VTOC expiration date using
TSIDVUT RETAIN. Expired files in a BIM-EPIC disk pool are
eligible for immediate reallocation.
3 In all JCL that refers to the dataset, change the dataset EXTENT
statements to specify a starting track of 1 or the number
specified in the STRTRK configuration option.
