Oracle internals, debugging and undocumented features
I am extremly busy these days and do not have any time to blog.That’s why my friend Granville Bonyate decided to write few small posts.Here is the first on in series.
Having worked with Oracle for many (twenty!) years, I sometimes find new features released several years ago that I didn’t catch at the time. Most recently, it would be that 10g added the display_cursor function to dbms_xplan. Most usefully, you can pass in the Sql-Id (from v$sql) and get the formatted execution plan for a SQL statement: Select * from table(dbms_xplan.display_cursor(‘d5dj7zctjwy1y’)); More information here:
Very useful when you’re at a site that doesn’t have TOAD or OEM.
