You can add one or more disk volumes to
a rapidly growing VLDB without bringing down the instance.
In Chapter 6, we talked about bigfile tablespaces and how they not only allow the total size of
the database to be much larger than in previous versions of Oracle, but also ease administration by
moving the maintenance point from the datafile to the tablespace. Chapter 15 will focus on Oracle
Net, providing you with the basics for ensuring that your clients can reach the database servers in
an efficient and prompt manner. Chapter 16 will expand our coverage of bigfile tablespaces in
addition to presenting other tools to make large database management easier, such as partitioned
table support, transportable tablespaces, and new to Oracle 10g, Oracle Data Pump.
As your databases get larger, and the number of users increases, the need for availability becomes
even more critical. Real Application Clusters (RAC) will tie together OMF, bigfile tablespaces, a
robust network infrastructure, and ASM into key elements of the RAC architecture. In this chapter, we
will revisit many of these database features, but with an emphasis on how they can be leveraged in
a RAC environment.
This chapter focuses on a number of RAC topics, including how to set up your operating
system environment??”kernel parameters, network configuration, and user accounts. You will
perform the requisite installations to support RAC, such as Cluster Ready Services (CRS) for
creating a clustered environment, along with the various installation options within the Oracle
Universal Installer (OUI) to configure your network, shared storage, and database software
installation for both CRS and the Oracle 11g database itself.
