Hello Peter;
Just anecdotal evidence -- no concrete logs etc... just wanted to see
if anybody knew any issues there before I started a more involved
investigation. The new method I am trying is;
java.util.UUID.randomUUID().toString();
cheers.
I've been using this and haven't had a
problem..... yet.
Which cases have you found that it's not unique?
If you find a different method, do you mind posting it here so we can
look into it too?
...
The method;
EOTemporaryGlobalID.assignGloballyUniqueBytes(..)
...has javadoc that reads;
Assigns to uniqueBytes an array of bytes
that represent a byte string that's guaranteed to be unique network
wide.
In production I believe that I have seen some cases where it might not
be completely unique. Has anybody else come across this sort of
problem with the TGID before I start looking at the J2SE equivalent.
