Oracle Health Check - How to use TOAD to Rectify the issues involved

Hi ,

I am working in a Web-based Environment on Windows 2003 R2 and Oracle 9.1. For the past some time, I have been experiencing a crawling Oracle database. The reports which used to take a few seconds are now taking minutes. The users are not able to connect to the database and complain of very slow database. Since, I am new Database Administration, I used the TOAD Health Check to find out what’s wrong with the Server. Can any of the expert assist me in resolving the issues involved.
