Description:

PDS is not working and we see this in $LOGDIR log file:

Undefined subroutine &HTTP::SimpleLinkChecker::user_agent called at /exlibris/aleph/a20_1/alephm/source/ext/check_url.pl line 4.
Undefined subroutine &HTTP::SimpleLinkChecker::user_agent called at /exlibris/aleph/a20_1/alephm/source/ext/check_url.pl line 4.

Error: URL did not return 200. PDS server down? URL:http://xx.xx.xx.xx:80/pds
 

Resolution:

If you encounter a problem with one of the following (Aleph 20):

(1) Checking validity of a URL in GUI Cataloging
(2) Running the batch process p_print_11
(3) Running PDS in the Web OPAC

First, check your version of SimpleLinkChecker by using the following command:

perl -MHTTP::SimpleLinkChecker -e 'print "$HTTP::SimpleLinkChecker::VERSION\n"'

If the result is "1.04", you need to update to version "1.15".

Contact your Ex Libris Support team to provide you with version 1.15.

After replacing the file check the version of SimpleLinkChecker with the command above. The result should be "1.15".

Try 
$aleph_product/local/perl/bin/GET https://google.com

If you get some http data, this means that the problem has been solved.
