Nice piece of work Brian, congratulations.
Can you explain a bit more about the 'fixed length' of a char?
CHAR in PL/SQL defaults to 1 character.
x := 'AB';
This will fail with
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 4
If it is declared like this then I understand the problem:
x := 'AB';

I finally figured out the problem with the SQL*Net more data to
client problem. The developer defined output variables as CHAR
since he was only passing back a single character.
Well the max size of a CHAR field in a procedure is 32K and it's
fixed length so it was returning the value back to the calling program
along with another 32000+ spaces to fill it out to the max possible
size. And he was doing this with 10 fields so that's a mere 320K
of spaces sent back to the java pgm each and every time this pkg was
called! Hence the need for Oracle to break that down into
manageable pieces to send across the network.
A quick change to VARCHAR2 fixed the issue.
Initial testing showed this to only be an issue when the package
was called by java - I didn't see this ...more data.. when I called it
via sqlplus from the same client.
