Resolution

2659 RECORD LENGTH EXCEEDED - DSN (ddd)

Reason:

A spanned record in data set (ddd) exceeded the maximum Disk buffer size as set by sysparm IOMAXREC. Specify IOMAXREC with a value equal to the size of the largest spanned record and rerun the job.

IOMAXREC - This sysparm specifies the maximum logical record size for data sets processed by Disk. The default value is 65,000 bytes. The maximum value for this sysparm is 999,999 bytes. To save real storage, this sysparm should be set to the lowest value possible that still allows normal Disk  processing. Not available when using the DFSMSdss Data Mover interface. 

The value of the IOMAXREC should be greater than the MAX LRECL as per a LISTCAT of the concerned data set named in message 0394:      
 ADSVS067 2545 GET: WORK AREA NOT LARGE ENOUGH FOR DATA RECORD         
 ADSVS060 0394 dsname WAS NOT ARCHIVED DUE TO PREVIOUS ERROR
