Glossary

The SORT/XL subsystem has been modified to support Large File functionality available in release 6.5. SORT/XL can handle multiple input files and the sum of the input file sizes cannot be larger than about 107GB. SORT/XL normally allocates two scratch files each of which is about one hundred twenty percent larger than the sumn of the input files and those files must be smaller than the maximum object size of 128GB.

The maximum native mode data type record length handled by SORT/XL has been raised to about 32,000 bytes from the current limit of 4096 bytes. The actual maximum record length depends on the number and length of the keys.
