Unfortunately I do not have a solution your problem. We are still on
MPE 5.0(I know, Y2K is lurking), and I have not had time to put Java and
the appropriate patches on our 3000 so I can test it. I am interested
in timings of record retrievals using RMI on the 3000. I am concerned
about Object Serialization performance. Do you mind sending me some
timings/specs on retrieving records from the 3000 via RMI. I am
currently testing a beta of Adager's ADBC. I test timings on a dataset
of approximately 10,000 records, 546 bytes wide( 5 char columns(total 64
bytes), 7 I1, 4 R2, and 44 R4 columns ). It takes 10-12 seconds to pull
all 10,000 records to a client(266mhz Pentium, NT4.0, jdk1.2). If I
pull only 2 columns( U18 and U2 ), it takes 3-5 seconds. We have an
HP928 with 256 meg ram. Both Client and Server are on the same 10BaseT
network. I do want to note this is these times are based off the time
the last record has been retrieved. The first record is retrieved and
viewable almost instantaneously.

I know that this does not solve your current problem, but I will send
you a snip of ADBC update code offline. You may also be aware that
MiniSoft has a JDBC solution as well as HP. I am looking forward to
trying them both out.
