Have you used the DRCP settings in DBD::Oracle?

From the description of DRCP, it sounds like you should never lose the
connection. You may want to check the configuration.
From your debugging output, it looks like the
Hi Perrin,
The DRCP settings is configured as the document expects.
I made a simple script outside mod_perl and use DBI to test re-connect to
Oracle. The test shows where the problem is.
#!/usr/local/bin/perl
use DBI;
print first connect\n;
$dbh = DBI-connect('dbi:Oracle:','...','...');

That all sounds good. 0E0 is a true value in Perl. It means zero but
true. And undef is a false value. You don't need
I don't actually understand why you did that. What was wrong with the normal
ping?
With Oracle DRCP, even though ping succeeds, the connection to the server
process is actually terminated. Or ora_ping() may return 0E0 zero but true
and undef. I don't know. ora_ping() is foreign to me. I
one correct - In both cases, the return value is evaluated to false.
How do you distinguish?

OE0 as a string evaluates to true. If you use it as a bareword /
numeric then it's false, which is what your eval example below is doing.

So it returns string '0E0'? The document didn't say that.

It is in the DBI documentation. Search for 0E0.

I only looked at Apache::DBI not DBI document.
My test program works. It reconnects to database OK. I ran it multiple times
and every time it reconnects OK. But Apache::DBI doesn't work. You saw the
previous debugging info. Where is the problem?

Sorry, I can't determine the problem from your log. You'll need to either
run it in the debugger or add some debugging print statements to figure out
where it's having trouble. All I can say from that output is that it it's
not succeeding in making a new connection after the ping fails, because
That's fine. I can do more debugging.
But I have hard time to understand this line of code:
200 if ($Connected{$Idx} and (!$needping or eval{$Connected{$Idx}-ping})) {
Should this be:
200 if ($Connected{$Idx} and ($needping and eval{$Connected{$Idx}-ping})) {
What's the difference
That line stops it from running the ping if $needping is false. The or
and || operators in Perl are sometimes called short circuit operators
because of this.

As I turned on more debugging, when the problem occurs, the Apache cached
connection reference is different than the database handle reference the query
is using. It almost looked like the query is executing on a completely
different database handle. Sometimes the query can succeed but
