[OPEN-ILS-DEV] Adding Z39.50 host

[Bill Ott]

Has anyone else added additional Z39.50 hosts to search?

I thought this would be a simple matter of adding the host into the 
opensrf.xml <z3950> section.  However, the few I've tried have failed.  
Am I missing something?



My osrfsys.log, it looks like the initial search completes, in this case 
returning 2 hits

 From my gateway.log.  It looks like this is actually an error while 
trying to report an error.

So, I threw the following at the perl debugger, and sure enough, I get 
two records.

use ZOOM;

$host='library.usc.edu';
$port='2200';
$db='unicorn';

$conn = new ZOOM::Connection($host, $port,
                                  databaseName => "$db");
$conn->option(preferredRecordSyntax => "usmarc");
$rs = $conn->search_pqf('@attr 1=4 @attr 4=6 "learning perl"');
$n = $rs->size();
print $rs->record(0)->render();
