  39. In database computing, Oracle Real Application Clusters (RAC) — an option for the Oracle Database software produced by Oracle Corporation and introduced in 2001 with Oracle9i — provides software for clustering and high availability in Oracle database environments. Oracle Corporation includes RAC with the Standard Edition, provided the nodes are clustered using Oracle Clusterware.
    Oracle RAC allows multiple computers to run Oracle RDBMS software simultaneously while accessing a single database, thus providing clustering.

    In a non-RAC Oracle database, a single instance accesses a single database. The database consists of a collection of data files, control files, and redo logs located on disk. The instance comprises the collection of Oracle-related memory and operating system processes that run on a computer system.

  40. Performance tuning is a broad and somewhat complex topic area when it comes to Oracle databases. Two of the biggest questions faced by your average DBA concern where to start and what to do. All you may know is that someone (a user) reports a problem about a slow or poor performing application or query. Where do you even begin to start when faced with this situation?
    Oracle's emphasis on this particular methodology changed when Oracle9i was released. The approach has gone from top-down in 8i to that of following principles in 9i/10g. Neither methodology is absolute as each has its advantages and disadvantages.

    The Oracle Server is a sophisticated and highly tunable software product. Its flexibility allows you to make small adjustments that affect database performance. By tuning your system, you can tailor its performance to best meet your needs.
    Performance must be built in! Performance tuning cannot be performed optimally after a system is put into production. To achieve performance targets of response time, throughput, and constraints you must tune application analysis, design, and implementation.
