Oracle ASM installation consists of installing and creating an Oracle ASM instance and configuring the required Oracle ASM disk groups. An Oracle ASM disk group is a collection of disk devices to store data files that Oracle ASM instances manage as a unit. Oracle ASM instances mount disk groups to make Oracle ASM files available to database instances.
Before You Begin
Ensure that the Oracle Grid Infrastructure software is already installed.
Ensure that the Oracle RAC framework is running on all nodes where the Oracle ASM instance is to be created.
Ensure that the file system where the Oracle ASM $ORACLE_HOME directory will reside is already created.
Use Oracle ASM Configuration Assistant (ASMCA). See the appropriate Oracle ASM documentation for instructions.
