After RHEL6-7 migration setting up oracle jws web servers says "error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory "
/apps/oracle/jws-webserver-3.0.3/jws_proxy/httpd/sbin/httpd: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory
Well, it looks like your migration messed up a couple of things.
Check if you actually have or not the library.
find / -name libpcre.so.1
If you do, then check your LD_LIBRARY_PATH, if not, then add the path to it so the binary can get it.
Another option is, pcre is not even installed, then process to get it and install it.
