If you upgrade the operating system for all devices from SLES 11 SP3 to SLES 12, Access Gateway fails to start. The following error message is displayed:
/opt/novell/apache2/sbin/httpd: error while loading shared libraries: libpcrc.so.0: wrong ELF class: ELFCLASS32
This happens because Access Gateway dependencies do not get copied during an operating system upgrade.Workaround: Reinstall Access Gateway or create the following symbolic links at Access Gateway server:
ln -s /usr/lib64/libpcre.so.1.2.1 /usr/lib64/libpcre.so.0 ln -s /usr/lib64/libdb-4.8.so /usr/lib64/libdb-4.5.so ln -s /usr/lib64/libodbc.so.2.0.0 /usr/lib64/libodbc.so.1 ln -s /usr/lib64/libesmtp.so.6 /usr/lib64/libesmtp.so.5
