Load-Balancing a RAC Database
 
01:05:46
RAC environments are very complex ones and include many different components. One of the goals of RAC database is to balance the load between the different instances and listeners. In this session we will dive into the load balancing mechanism. We will talk about the client configuration, SCAN listeners, services and more, and see some guidelines and best practices to better utilize the balance between the nodes.

Oracle RAC Components | Basic cluster components
 
12:51
https://dbagenesis.com/p/oracle-11gr2-rac-for-beginners A computer cluster consists of a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (i.e. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, and/or different hardware.

Introduction to Oracle Listener
 
16:41
https://dbagenesis.com/p/oracle-11g-advanced-dba DBA Genesis provides all you need to build and manage effective Oracle technology learning. We designed DBA Genesis as a simple to use yet powerful online Oracle learning system for students. Each of our courses is taught by an expert instructor, and every course is available on demand. A listener is a separate process than your database processes which runs on the database server to accept incoming connections. Any client connection first lands on to database listener and then its handed over to the PMON process. All the databases running on a server must have their services registered with the listener or else listener will not be able to accept the incoming connections.

Part 5: Partition creation, ASM RPM installation & ASM DISK creation & grid software Installation
 
22:03
Real Application Clusters Oracle Real Application Clusters (RAC) is a database clustering solution that allows more than one instance to mount and open an Oracle database. RAC can only be used on special clustered systems with shared disk storage and a private network interconnect. A normal Oracle installation consists of a single Oracle instance that accesses a database on the same computer system. In contrast, RAC allows multiple instances on different computer systems (nodes in a cluster) to access the same database files simultaneously. Communication between instances is managed by the Distributed Lock Manager (DLM). To address the possibility of two or more instances attempting to modify the same information simultaneously, Oracle uses up to ten additional background processes, named LCK0 through LCK9, to lock the resources in use by these instances. RAC is available with Oracle Enterprise Edition, and under certain conditions, with Standard Edition as well. These restrictions (for Standard Edition) include: • Must use Oracle Clusterware (no third-party clusterware allowed); • Must use ASM to store database files; and • Can only use a max of 4 CPU sockets in the cluster (either 2 nodes with 2 CPUs each, or 4 nodes with 1 CPU each). • RAC was previously called Oracle Parallel Server (OPS). Oracle re-branded OPS as RAC when they released Oracle 9i. Benefits Running Oracle in RAC mode can benefit you in the following ways: • High availability - If some nodes fail, the remainder of the nodes will still be available for processing requests. Failover support is available from Oracle 8 with Oracle's Transparent Application Failover (TAF) technology and from Oracle 10g, server side load balancing. • Speedup (increased transaction response time) - RAC normally adds some overhead. However, for some DSS applications one can achieve increased performance by running operations in parallel (mainly for DSS applications). • Scale-up (increased transaction volume) - RAC can be used to provide increased application scalability (mainly used for OLTP applications).

01 Overview of table Partition in oracle
 
07:26
Partitioning enhances the performance, manageability, and availability of a wide variety of applications and helps reduce the total cost of ownership for storing large amounts of data. Partitioning allows tables, indexes, and index-organized tables to be subdivided into smaller pieces, enabling these database objects to be managed and accessed at a finer level of granularity. Oracle provides a rich variety of partitioning strategies and extensions to address every business requirement. Moreover, since it is entirely transparent, partitioning can be applied to almost any application without the need for potentially expensive and time consuming application changes. Partitioning allows a table, index, or index-organized table to be subdivided into smaller pieces, where each piece of such a database object is called a partition. Each partition has its own name, and may optionally have its own storage characteristics. From the perspective of a database administrator, a partitioned object has multiple pieces that can be managed either collectively or individually. This gives the administrator considerable flexibility in managing partitioned objects. However, from the perspective of the application, a partitioned table is identical to a non-partitioned table; no modifications are necessary when accessing a partitioned table using SQL queries and DML statements. Partitioning Key ======================== Each row in a partitioned table is unambiguously assigned to a single partition. The partitioning key is comprised of one or more columns that determine the partition where each row will be stored. Oracle automatically directs insert, update, and delete operations to the appropriate partition through the use of the partitioning key. When to Partition a Table ========================== Here are some suggestions for when to partition a table: Tables greater than 2 GB should always be considered as candidates for partitioning. Tables containing historical data, in which new data is added into the newest partition. A typical example is a historical table where only the current month's data is updatable and the other 11 months are read only. When the contents of a table need to be distributed across different types of storage devices. When to Partition an Index ============================= Here are some suggestions for when to consider partitioning an index: Avoid rebuilding the entire index when data is removed. Perform maintenance on parts of the data without invalidating the entire index. Reduce the impact of index skew caused by an index on a column with a monotonically increasing value. Partitioned Index-Organized Tables =================================== Partitioned index-organized tables are very useful for providing improved performance, manageability, and availability for index-organized tables. For partitioning an index-organized table: ============================================ Partition columns must be a subset of the primary key columns Secondary indexes can be partitioned (both locally and globally) OVERFLOW data segments are always equi-partitioned with the table partitions See Also: Oracle Database Concepts for more information about index-organized tables System Partitioning System partitioning enables application-controlled partitioning without having the database controlling the data placement. The database simply provides the ability to break down a table into partitions without knowing what the individual partitions are going to be used for. All aspects of partitioning have to be controlled by the application. For example, an insertion into a system partitioned table without the explicit specification of a partition will fail. System partitioning provides the well-known benefits of partitioning (scalability, availability, and manageability), but the partitioning and actual data placement are controlled by the application. See Also: Oracle Database Data Cartridge Developer's Guide for more information about system partitioning Partitioning for Information Lifecycle Management Information Lifecycle Management (ILM) is concerned with managing data during its lifetime. Partitioning plays a key role in ILM because it enables groups of data (that is, partitions) to be distributed across different types of storage devices and managed individually.
