[Quoted] Hello everyone,

I had a weird problem on Friday (see the log entry). Apparently, a stored function (a simple one) would work with some parameters and not with others. After I re-compiled the function (and it was a "VALID" object) it would work. I had another problem earlier that day with a trigger which reported the same error (I don't know were the error was occurring because it started to work when I did the re-compiles of all objects). As mentioned in the log, I re-compiled all of USER's objects (procedures, functions, & packages) whether they needed it or not, and got my application up and running.

The reason why I bring this up is, did anyone see a simular occurance elsewhere? Is this a known bug?

Let me know what you think!

[Quoted] At 1615 hours, an user had reported that his data was not updating. After
looking at the problem, I found that none of the data was updating. I investigated the APPL extraction process and found that the process had
been reporting errors since 0815 hours, with the following error:

  Getting ORA Module Data Controls Error:   ORA-06502: PL/SQL: numeric of value error   ORA-06512: at line 1

Looking at the source code, if found that it was getting the error when executing the stored function get_MDC. I found that the function would work

when on get_MDC('DP_PERIOD') &  get_MDC('DP_HISTORY'), but not for
get_MDC('DB_SHUTDOWN'), get_MDC('DB_EXCEPTION'),
get_MDC('DP_FLUSH_PERIOD'),

and get_MDC('DP_DEAD_BAND'). There was no reason for some to work and some
not, so I tried recompiling the stored function (even though it was "VALID"),
and it started to work properly. Since I experienced a simular problem in the
creation of an account in the APPL account definition page, I decided to compile all
stored PROCEDURE's, FUNCTION's, PACKAGE's, PACKAGE BODY's. After shuting all
SQL*net connection down I re-compiled the objects. APPL was restored to

service at 2000 hours.
