Aleph is Unable to contact the PDS server though the pds URL is OK

• Article Type: General
• Product: Aleph

Description:
In the www_server.log the following error appears:
execlp: No such file or directory
Error: URL did not return 200. PDS server down? <pds_url>

When entering the pds_url in the browser - it is OK and the Aleph server can reach the PDS server via telnet / wget.



Resolution:

When Aleph tries to contact the PDS server, it uses the check_url.pl script that is located in $aleph_ext.
Make sure that the first line in this script exists and directs to the correct location:

> head -1 check_url.pl
#!/exlibris/aleph/a20_1/product/bin/perl

> ls -lrt /exlibris/aleph/a20_2/product/bin/perl
