Secondary index
You must define one Secondary index for each data store and initialize it with a header record.
This is an example of JCL for the scratch and creation of the secondary
index file:
//DELSKI EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
DELETE OPCDEV.SKI0X CLUSTER PURGE
//*----------------------------------------------------------------
//DEFSKI EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DEFINE CLUSTER(NAME(OPCDEV.SKI0X)-
