Issue/Introduction

An EZT program was created with the input file DD concatenating 2 VSAM files. The execution receives an error.

  Specific information for this return code: Specific information for this 
  return code: An attempt was made to open concatenated VSAM data sets.    
  Concatenation of VSAM data sets is not supported. This error can also    
  occur if the TIOT contains old entries and has not been refreshed after  
  the data set has been moved. For example, in the case of a               
  DELETE/DEFINE/REPRO in the same step and using the OUTFILE parameter     
  instead of the OUTDATASET parameter (which causes the allocation         
  information to be refreshed).

  Correct the JCL DD statement identified in the "ddn" field of the message
  by removing data set concatenation and rerun the JOB.     

Some other options to process 2 VSAM files:

-  Review Synchronized File Processing

-  Repro the VSAM files to sequential files, merge and sort them. Use the sequential file as input to the EZT program.
