4 Administering Oracle ASM Disk Groups
Administration of Oracle ASM disk groups includes creating, altering, dropping, mounting, and dismounting tasks.
This chapter describes how to administer Oracle Automatic Storage Management (Oracle ASM) disk groups. This information includes how to create, alter, drop, mount, and dismount Oracle ASM disk groups. The database instances that use Oracle ASM can continue operating while you administer disk groups.
The examples in this chapter use SQL statements. These examples assume that SQL*Plus is run from the Oracle grid home where Oracle ASM is installed and the Oracle environmental variables are set to this home. The examples also assume that the Oracle ASM instance is running. This chapter contains the following topics:
