hmmm...in my lock method (which adds recNo, randomLong to a hashMap) can I just call the raf.lock() to lock the file...i think so? then just lock the section where this record is...thoughts, comments appreciated...

thanks

Hi Lucy,

Locking the entire file is not a good idea as it essentially brings concurrency to zero. What you need to investigate is logical per-record locks.

Best Regards,

Czarak.
