IDC3306I ** PS PROCESSING INVALID FOR KEYED DATA SET
Explanation
Physical sequential access is not possible for the data set. Indexed sequential access method (ISAM) data sets may not be processed other than sequentially by key.
System action
The system ends processing of the command.
System programmer response
If the error recurs and the program is not in error, look at the messages in the job log for more information. Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the JCL and the SYSOUT output for the job.
Programmer response
Change the JCL statement to specify a virtual storage access method (VSAM) data set, or correct the usage of the data set.
