Description:
------------
DB2(AIX 5.3/ DB2UDB 8.2/ 64bit instance)
 |
 |<-----------A_PLATFORM) windwos advanced serve 2000/Apache2.0.55 (Win32) PHP 5.1.1/pecl idbm_db2 1.1.6
 |
 |<-----------B_PLATFORM) AIX 5.3/Apache 1.3.34 64bit compile/PHP 5.1.1 64bit compile/pecl idbm_db2 1.1.6


A_platform & B_platform are using identical DATABASE server.
and php source for test is same too.
but result sets at A_platform/B_platfrom are different.


sorry my poor english

Sorry.
Platform was reversed.

Result set at A_platfrom(windows) are right.

Result set at B_platfrom(aix 5.3) are wrong. 
B_platform is buggy.

[2005-12-18 00:27 UTC] denials at gmail dot com

Interesting; this appears to be a type mismatch issue that just happens to work on 32-bit.

I've applied a simple patch to CVS head to try to enforce stricter type matching, but will get my hands on a 64-bit machine to actually test it out in a few days.

[2006-01-03 09:07 UTC] denials at gmail dot com

Hey, Krishna -- happy new year! Any chance you can reproduce and / or fix this?

[2006-01-10 14:03 UTC] denials at gmail dot com

Hellower, can you try the ibm_db2 package from CVS HEAD and let us know if that fixes the problem for you?

It would be great if you could give the ibm_db2 unit tests a run as well (you'll need to create the SAMPLE database by issuing the db2sampl command).

[2006-01-14 02:21 UTC] hellower at nate dot com

Still not solved.

i sent you mail(Please check your Gmail account)

sorry for my poor english.

[2006-02-09 08:49 UTC] denials at gmail dot com

Slow but steady progress -- the crash on connect should be resolved with the latest code from CVS HEAD. We had longs instead of ints for the char string lengths in _php_db2_connect_helper().

If you get the chance, could you run the unit tests in the ibm_db2/tests/ subdirectory and post the results here? Assuming you are currently in the /ibm_db2/ directory, edit ibm_db2/tests/connection.inc to reflect your DB2 connection credentials and then run the following command:

pear run-tests tests/

Thanks!

[2006-03-12 01:21 UTC] kfbombar at us dot ibm dot com

Are you still having an issue with the code from CVS HEAD?  Also, did you run the tests in ibm_db2/tests subdirectory as denials requested?  Please let us know so we can help you out.

Thanks for the info!

[2006-03-19 07:05 UTC] hellowre at nate dot com

Sorry for late response.--;

Currently, the test machine is out of order(h/w problem)
so, tape device is not regnized at server.

So, I can't recover test machine using backup tape.
Please, wait until a test machine will be recovered.

sorry for my poor english.
