The
VERIFY command attempts to open a VSAM data set in order to verify that it can be read and that the index is usable. The data set
is assumed to be readable if it can be opened without error or if it is locked to another process.
If the index is found to be unusable, the
VERIFY command rebuilds the index by creating a new index file for the primary key and all alternate keys. The data portion of the
data set is not changed.
Parameters:
MFJAMS supports the following parameters. They are supported as documented in the IBM documentation unless otherwise stated below:
- FILE(ddname)
- Name of the
DD statement, contained in the JCL for this job step, that provides the name of the data set that is to be verified.
- DATASET(data-set-name)
- Name of the data set.
Comments:
FILE and DATASET are mutually exclusive. You must specify one of them.
