Hello,
I wonder if someone could possible help me with an issue
regarding Tie::RDBM.
I am using it on a mod_perl 2.0 enabled website with apache
2.0.51 with persistent database connections to a postgresql-backend.
Everything works fine, but every once in a while there will
be an error in the error_log stating:
Can't call method "fetchrow_arrayref" on an undefined value
at /usr/lib/perl5/site_perl/5.8.3/Tie/RDBM.pm line 166
Module version is 0.7
I use the Tie::RDBM functinonality to translate contents
of webpage like this:
print<<HTML;
<h1>$translate{welcome_fellow}</h1>
<h2>$translate{this_is_an_example}</h2>
HTML
where the %translate hash is either tied to a table including
German key/value pairs, or English, Danish, Polish or whatever.
Now sometimes it happens, that some keys within a single
webpage are translated, but suddenly there's one particular
key, where the above error is raised and script execution is
terminated with a 500 Internal Server Error.
My only explanation is that the connection to the backend dies
for some reason just between two requests to the backend.
Did you anyone ever encounter such trouble? Can you give me a hint?
Or would it make sense to modify the Tie::RDBM module by adding
a check whether the backend is still alive just before executing
a statement?
Any help appreciated,
thanks in advance,
