Is anyone out there using the IBM java toolkit record level
i/o classes in a multithreaded environment (all servlets, for example, are
multithreaded)? If so and you using the toolkit RecordFormat or
AS400FileRecordDescription classes, you may have a problem. The websphere
joblog says one or both of these classes is using DSPFD and DSPFFD under the
covers to retrieve the record format and field descriptions. These
commands are not threadsafe in either v4r3 or v4r4. You should see
messages in your joblog like "Command *LIBL/DSPFFD not safe for job with
multiple threads." and "Command *LIBL/DSPFD not safe for job with multiple
threads.".
While the actual i/o to a file may be threadsafe, retrieving
the record format and field descriptions is NOT. I cant believe I am going
to have to hardcode my file record formats in my java code. We are using
the latest mod2 toolbox. Please tell me this is fixed in the beta mod3 or
will be by GA?
