The Oracle ACFS plugin functionality enables a user space application to collect just-in-time Oracle ACFS file and Oracle ADVM volume metrics from the operating system environment. Applications can use the Oracle ACFS plug-in infrastructure to create customized solutions that extend the general application file metric interfaces to include detailed Oracle ACFS file system and volume data.
The Oracle ACFS plug-in functionality can be enabled on separate Oracle ACFS file systems mounted on a standalone host or on one or more nodes of an Oracle Grid cluster where the Oracle ACFS file system is mounted. This functionality enables message communication between a node-local plugin enabled Oracle ACFS file system and an associated user space application module using Oracle ACFS plug-in application programming interfaces (APIs).
The plugin message APIs support both polling and posting message delivery models and multiple message payload types.
