SQL statement's execution plan
which is the same for all sessions that execute this SQL statement.
Data that cannot be shared by sessions that use the SQL statement are in the
private SQL area
. Such data are for example the values of
bind variables
.
The
shared SQL area
is part of the
library cache
.
The shared SQL area is sometimes referred to as
