Cause

1. Unix libraries are not linked properly.
2. A different version of Perl is used by Voyager.

Resolution

1. Link all *.so* libs from /oracle/app/oracle/product/11.2.0.3/db_1/lib to /lib.
cd $ORACLE_HOME/lib
for f in `ls ./*.so*`; do;
sudo ln -s $ORACLE_HOME/lib/$f /lib/$f
done

2. Run the following command to provide a soft link to resolve a missing DBD sub-directory in $ORACLE_HOME/perl/lib/site_perl/5.10.0/x86_64-linux-thread-multi/auto:
ln -s $ORACLE_HOME/perl/lib/site_perl/5.10.0/x86_64-linux-thread-multi/auto/DBD DBD

3. In oai-pmh.cgi, replaced #!/usr/bin/perl with #!/m1/shared/bin/perl to pick up the correction version of Perl.
