I have the following problem:
I have a production database(Oracle version 8.1.7) running on Windows2000,on which is running project with web interface(we are using jsp and tomcat). A few weeks ago something unexplainable has happened. A database became unreachable and I could not neither logon on the database server or the database. I checked the alert.log file, oracle.exe process but I could not find anything strange. A few times a day in the last weeks the database became unreachable and only thing I could do is to restart the database. But this doesn't solve my problem.
I will appreciate any suggestions!
