What is Oracle database grid?
The Oracle Grid Infrastructure for a standalone server is the Oracle software that provides system support for an Oracle database including volume management, file system, and automatic restart capabilities. Oracle Grid Infrastructure for a standalone server is the software that includes Oracle Restart and Oracle ASM.
What is the architecture of Oracle database?
An Oracle database system can easily take advantage of distributed processing by using its client/server architecture. In this architecture, the database system is divided into two parts: a front-end or a client, and a back-end or a server.
What is Oracle RAC and dataguard?
RAC provides for high availability (and scalability) “in a room”. Data Guard however provides for continuity of operations – if the room in which your RAC cluster resides “goes away” (fire, flood, explosion, whatever) data guard is “somewhere else, ready to take over”.
What is Oracle Grid Control?
Grid Control is a system management software that delivers centralized monitoring, administration, and life cycle management functionality for the complete Oracle IT infrastructure, including systems running Oracle and non-Oracle technologies.
What is database grid?
A Data Grid is a system composed of multiple servers that work together to manage information and related operations – such as computations – in a distributed environment. Unlike a relational schema, the application objects are often hierarchical and may contain information that is pulled from any database.
What is the difference between ASM and RAC?
Using ASM on a single-instance database means adding another software installation to the mix. Oracle RAC deployments require Grid Infrastructure anyway so using ASM for Oracle RAC does not require anything that isn’t already installed on the cluster nodes.
What is Oracle memory structure?
The basic memory structures associated with Oracle Database include: System global area (SGA) The SGA is a group of shared memory structures, known as SGA components, that contain data and control information for one Oracle Database instance. The SGA is shared by all server and background processes.
What is difference between Data Guard and RAC in Oracle?
so the difference between the two is that rac is highly available whereas the dataguard ensures data integrity. Since if the one oracle instance in rac has problem, then a restore will be inevitable. no. If one node goes down, the other node will take over for it.
What do you need to know about Oracle Grid architecture?
Overview of Oracle Grid Architecture. Grid computing is a new IT architecture that produces more resilient and lower cost enterprise information systems. With grid computing, groups of independent, modular hardware and software components can be connected and rejoined on demand to meet the changing needs of businesses.
What kind of architecture does Oracle Database use?
An Oracle database system can easily take advantage of distributed processing by using its client/server architecture. In this architecture, the database system is divided into two parts: a front-end or a client, and a back-end or a server.
How to install grid infrastructure on a database?
To install Oracle Grid Infrastructure for an existing database: On the same host computer as the database, use Oracle Universal Installer to install Oracle Grid Infrastructure, and select Install and Configure Grid Infrastructure for a Standalone Server as the installation option. Go to the Grid home’s bin directory.
What are the components of the Oracle 11g architecture?
Oracle Database 11g Architecture Basically, there are two main components of Oracle database –– instance and database itself. An instance consists of some memory structures and the background processes, whereas a database refers to the disk resources. In this section, will cover the following topics related to the Oracle architecture:
