Grid Infrastructure is Oracle’s platform for running Oracle databases (single instance or RAC) and other services (e.g. Apache web servers) in a highly available, fault tolerant, manner. It includes facilities for shared storage (ASM, ASM Clustered File System/ACFS, aka Cloud FS) and network name and address management that underpin the capability to keep databases, application servers, and third party products running and available at all times.
Database Administrators and OS System Administrators will find this class and Grid Infrastructure essential for running Oracle Databases.
Grid Infrastructure is a required prerequisite installation for all Oracle RAC and ASM installations. It is also required for the Oracle Restart facility. Grid Infrastructure is the way Oracle is moving, for all databases and application servers.
Oracle Certified Master John Watson will teach you how to install and use Grid Infrastructure to manage Oracle Databases. John will also demonstrate that Grid Infrastructure is not necessarily complicated and can indeed make your life simpler. You will however also learn that exploiting its capabilities to the full can give fantastic levels of performance and fault tolerance, at a far lower cost than any competing products.
The environment is a two node Linux cluster for each student, to be configured starting with nothing more than the operating system installed.
Technical Requirements
Nothing is required for labs (workshops). SkillBuilders will provide everything you need for all hands-on labs. Modest PC or Mac specs are required to connect to the online class. Detailed specs can be found here.
Also, we strongly recommend using two monitors for this class.
