Thanks Kirk, I have multiple threads reading from and writing to a KSDS. After some reads I need to release the record lock. I can see there is a locate() method which I assume is a wrapper to flocate() and flocate() releases all record locks, according to the doc, so I'll try locate().

The methods are pretty much derived from the C library I/O functions. One common thing that ENDREQ is used for is for using a VSAM ACB to submit jobs to the internal reader and give you back the jobid. JZOS does have a class MvsJobSubmitter that does this. It does not expose a low level VSAM api. 2) There is no fread_unlocked in the ZFile class. You can use the javadoc or open the class file in an IDE to see exactly what methods are there.
