But that's begging the question. What actually occurs that allows you to say that there is a "context switch" ?
I know that one of the advertised performance enhancements in v9 was the 'more efficient context switching between SQL and PL/SQL' (or some such thing) - but a name is not a thing. Does the Oracle process run as a virtual machine, and build two completely independent top-level heaps/stacks and maintain a set of virtual registers - one for an SQL environment and one for a PL/SQL environment ? Do you get multiple "contexts" if SQL calls a pl/sql function that opens a cursor that calls a pl/sql function ? Can anyone put a description under the name ?
