31: Oracle RAC - Failover and Load Balancing
Oracle RAC systems provide two methods of failover to provide reliable access to data:Connection failover and Transparent Application Failover
32: Installing Oracle Real Application Clusters
Install Oracle Clusterware and Oracle Database software using Oracle Universal Installer (OUI), and create your database with Database Configuration Assistant (DBCA). This ensures that your Oracle RAC environment has the optimal network configuration, database structure, and parameter settings for the environment that you selected.
33: RMAN Backups
Backing up all or part of your database is accomplished by using the BACKUP command from within the RMAN client.RMAN uses the configured settings and channels for your database, the record of previous backups in the RMAN repository and the control file's record of the structure of your database to determine an efficient set of specific steps to perform in response to a BACKUP command, and then carries out those steps.
34: MS SQL Server Versions
The latest version of SQL Server is Microsoft SQL Server 2005, this was released on 7th November 2005, at the time of writing this article I do not know of many organisations that are utilising SQL Server 2005 in a production environment but many organisations that utilise Microsoft SQL Server as a database solution have SQL Server 2005 setup in a test environment and have plans to migrate their production environments to this latest version in the future.
35: Oracle Real Application Clusters
Oracle RAC extends Oracle Database so that you can store, update, and efficiently retrieve data from multiple instances on different servers at the same time. Oracle RAC provides the software that allows the servers to work together in what is called a cluster.
36: Oracle Security - Get to know the basics
This article is aimed to help DBAs to assess their current level of risk, and then provide practical, applicable knowledge to appropriately secure the Oracle database. This article is designed to help you establish a practical security program for Oracle databases. We will create a means for measuring and assessing the security of your databases, and give you tools to create a security scorecard for each of your Oracle databases.
