Hi All,

Is this grid technology and RAC is somehow quite same. Because in RAC
is good when we have so many server as well as according to grid it
uses the shared data among many servers.
Infact somehow grid is better because in RAC only one query is handle
by one server but in grid, the result will be fetch by all servers if
they have it's output in their sga.
I understand features of 10g but what is grid is confusing to me.
I know it is stupid question for some of you. Please clear my this
doubt.

Thanks

Only if you listen to the befuddled message put out my Oracle marketing.
The technologies are completely independent. You can have RAC without
GRID. GRID without RAC. Or both.

Actually it is not a stupid question. From day one Oracle has botched
the grid message creating confusion. RAC is a great solution to the
problem of servers and instances as a single point of failure. Grid has
nothing to do with that at all except that it can be used as a tool to
manage and provision RAC clusters.

If Oracle would clean up the message I suspect sales would go up.

A -Enterprise Grid - in Oracle related technology means :

Storage Grid : Automatic Storage Management
Database Grid : RAC
Middleware Grid : Application Server Farms or Clusters
Grid operations : Oracle Enterprise Manager Grid Control

And there are mechanisms related to AS and RAC that are grid related.
eg. FaN - Failure of a RAC node is signaled to the AS grid.

Grid Related Information here :

hope it helps.
