RE: JAVA Stored Procedure

["Himes, Jay" <jehimes@xxxxxxxxxxx>]

I tried creating a function based on the ones Patrick sent; however, now I
get the error below. 
I suspect there is a log somewhere that would give me more details but I
have no idea where to look. 
Does anyone have any ideas?

 Message ID . . . . . . :   CPF503E       Severity . . . . . . . :   30

 Message type . . . . . :   Diagnostic

 Date sent  . . . . . . :   04/02/04      Time sent  . . . . . . :

 Message . . . . :   User-defined function error on member NAMMSP.

 Cause . . . . . :   An error occurred while invoking user-defined function

   SYSDOWN in library LBUCMUSR. The error occurred while invoking the

   associated external program or service program s!getsysst in library

   storedproc, program entry point or external name ate. The error occurred
on 
   member NAMMSP file NAMMSP in library LBUCMFIL. The error code is 1. The

   error codes and their meanings follow:

     1 -- The external program or service program returned SQLSTATE 42724.
The 
   text message returned from the program is:
LBUCMUSR.SYSDOWNSYSDOWNget 
   .

     2 -- The external program failed before it completed.

     3 -- The database timed out waiting for the program to return. The
timeout

  value used by the database was 0 minutes and 30 seconds.

    4 -- The external program no longer exists or is not found.

    5 -- One of the input parameters of the function had a data mapping
error.
    For an external program, the program entry point displayed will be *N.

Recovery  . . . :   For error codes 1 and 2, determine the cause of the
error 
  from either the SQLSTATE or a previously listed message.

    For error code 3, either increase the timeout limit using the QAQQINI
file
  setting or determine why the external program or service program did not

  return in the time allotted.

    For error code 4, ensure the program or service program exists for the

  duration of the query.

    For error code 5, determine the cause of the data mapping error.

    Try the request again.

Hey Jay

I've recently created a few Java SQL functions. I haven't run into the error
you did. Here is my Java code maybe it will help.

Thanx, PLA
