James,
The key parts in that output are -
2006-10-30 16:20:52 Thread-4136076976 ERROR http: snmehl_allocateListenerPort: f
ailed to bind socket: Address already in use (errno=98)

d to listen to HTTP port for http://localhost:3938/emd/mainThey are telling you that it could not bind to that particular port number (port 3938) because something else is already bound to it.
Try (as root) -
/usr/bin/lsof -i TCP:3938which should show you information about the process(es) that are currently listening on that port.
As for -
/app/oracle/product/10.2.0/companion/Apache/Apache/bin/httpd: error while loadin
g shared libraries: libdb.so.2: cannot open shared object file: No such file or
directorylibdb is a prerequisite of installing the Apache server, I believe you can get the library as part of the Berkeley DB installation/rpm's/packages (it should be listed in the installation document).
Hope this helps.
