Cannot completely reinstall Application Server
The Data Server is up and running, all data is loaded, and the enterprise manager is functioning as it should.
When the Application Server was initially installed there appeared to be a problem which I suspect was related to improperly constructed listener.ora and tnsnames.ora files. The enterprise manager for the Application Server did function, however; the Application Server was de-installed and a reinstallation initiated several times and while the database installed successfully every time, the Enterprise manager installation has failed.
