Here's a little test program I use to replicate the issue:
#!/usr/bin/perl -w
use strict;
use DBI;
my $dbh=DBI->connect('zzz','zzz','zzz');
while(1){
my $sth=$dbh->prepare_cached('select count(*) from EXAMPLE');
$sth->execute();
my @r=$sth->fetchrow();
print "$r[0]\n";
$sth->finish();
sleep 10;
}
$dbh->disconnect();
When I do the work to EXAMPLE that invalidates the statment handle, my example code returns the following:
DBD::Oracle::st execute failed: ORA-00942: table or view does not exist (DBD ERROR: OCIStmtExecute)
DBD::Oracle::st execute failed: ORA-01003: no statement parsed (DBD ERROR: OCIStmtExecute)
What I'd like is for prepare_cached to recover gracefully from these types of intermittent hiccups. Any ideas?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
