SQL1131N after installing a new shared library.

[Michel Esber]

Hello,

DB2 V7 FP 13 running on Linux.

We have developed a C++ shared library that will be called by a db2
stored procedure. Every time my developers generate a new .so shared
library, I copy it to /home/db2inst1/sqllib/functions/ and then run a
test applications that calls the stored proc. I also run a "bind
file.bnd blocking all grant public". The first execution of the
procedure (after the .so has been replaced) always fails with SQL1131N
(DARI (Stored Procedure) process has been terminated abnormally.)

However, if I invoke the same procedure again (using my test app or
CLP), it works like a charm. In fact, it will never fail again. The
error happens only during the first execution.

This leads me to think that there is no application / C code error. Do
I need to run any command after copying the new .so file, so DB2 can
"reload" the lib ? I am not sure what I am missing here.

Here are the diag and stack trace files:
