We have Oracle 9i in my company, and I am thinking to upgrade it to 10g,
I want to make the upgrade in a test machine before applying it to the main database server.
What should I do, what manuals should I read, all information Plz
If there is a risk of doing such thing, waht are alternatives? For example, We already have Toad connected to the database, and I can view all the data from it, but strang!!! I cannot insert or update any record in any table through Toad although I connect as SYSDBA, But with the SQL command I can.
