So you tried this:
[root@oamserver ~]# export LD_LIBRARY_PATH=/opt/apps/oracle/Middleware/Oracle_WG1/webgate/apache/lib[root@oamserver ~]# apachectl -k start
And ya got this:
httpd: Syntax error on line 1011 of /etc/httpd/conf/httpd.conf: Syntax error on line 9 of /etc/httpd/conf/webgate.conf: Cannot load /opt/apps/oracle/Middleware/Oracle_WG1/webgate/apache/lib/webgate.so into server: /opt/apps/oracle/Middleware/Oracle_WG1/webgate/apache/lib/webgate.so: cannot enable executable stack as shared object requires: Permission denied
Do this:
sudo vi /etc/selinux/config
Set this:
SELINUX=disabled
Reboot.
Piece.
