Oracle Solution for Error ora-00827

ORA-00827: could not shrink sga_target to specified value

What triggered the Error:

Attempted to shrink the SGA to the specified value but did not succeed because the SGA components could not be shrunk as they were already at their minimum sizes.

What should we do to fix it:

Do not set sga_target to a value below the current value without first shrinking the individual SGA components.
