Goal
In Oracle Database 11g, the FROM MEMORY clause creates a pfile or spfile using the current
systemwide parameter settings.
In a RAC environment, the created file contains the parametersettings from each instance.
During instance startup, all parameter settings are logged to the alert.log file.
As of Oracle Database 11g, the alert.log parameter dump text is written in valid parameter syntax.
This facilitates cutting and pasting of parameters into a separate file, and then using as a pfile for a
subsequent instance.
The name of the pfile or spfile is written to the alert.log at instance startup time.
In cases when an unknown client-side pfile is used, the alert log indicates this as well.
To support this additional functionality, the COMPATIBLE initialization parameter must be set to
11.0.0.0 or higher.
