Expression Support for Initialization Parameters

You can specify an expression when setting the value of an initialization parameter.

In previous releases, you were required to specify an absolute value when setting an initialization parameter. You can now specify an expression that takes into account the current system configuration and environment. This is especially useful in Oracle Autonomous Database environments.

Practice: Using Expressions in Initialization Parameters

This practice shows how to optimize the values set in initialization parameters when they depend on environmental characteristics, such as system configurations, run-time decisions, or the values of other parameters by using expressions.
