I have a program that has run without incident for 2+ years but now routinely hangs at random points during the data fetch cycle. It is a fairly simple program that fetches around 16000 records from an Oracle database on a different server and then builds a file from the results.
Unfortunately, no error or timeout occurs in the Perl program. This is the immediate problem since it is a cron job that kicks off at 7am and 11:30pm each day.
Since the Perl box is currently running Perl version 5.8.0, using $SIG{ALRM} is not an option. I'm looking at Sys::SigAction (there is a writeup on it here: http://search.cpan.org/~lbaxter/Sys-SigAction/dbd-oracle-timeout.POD) instead but was wondering if any knowledgeable Perlmonks might know of a different or preferred approach.

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).
