Hi Richard
I think the AS400FileRecordDescription object uses the DSPFD and DSPFFD
commands to build the record format objects.
Thanks
Neill

Are you calling DSPFD and DSPFFD or is the JT400 record level access API
caling it ?
If JT400 is calling it, I wouldn't be too alarmed since they must be
using these API's to get record layouts, however I would think they
would be using the API's instead to get metadata for a table. I would
imagine this would be faster than DSPFD/DSPFFD.

subject: RecordFormat threadsafety
Hi
For some time now I have been working on a multi threaded Java server
that will sit on the i5 (Power etc) and respond to requests from RPG via
a data queue.
Whenever the "Server" has to write back to files on the AS400, it uses
record level access, and each thread has its own AS400 connection object
for use with the KeyedFile object.
Everything seems to work ok, but I am a bit worried about messages that
are appearing in the Job log to say that the commands DSPFD and DSPFFD
are not thread safe.
I think that these commands are being called when the RecordFormat is
being created, does anybody have any tips for getting round this, or do
I just have to accept the fact that I cannot use threads in my server.
I am tempted to bin off record level access, and just use JDBC and SQL..
But before I do that are there any threading issue's I have to contend
with in JDBC?
Thanks, any help as always is very appreciated. Neill
