How to Install the ASM Software

ASM installation consists of installing and creating an ASM instance and configuring the required ASM disk groups. An ASM disk group is a collection of disk devices to store data files that ASM instances manage as a unit. ASM instances mount disk groups to make ASM files available to database instances.

You should decide the type of ASM instance you want to use. You can use ASM instance as single instance ASM or clustered ASM using Oracle Clusterware instances. For information on how to choose the appropriate ASM instance, see Choosing the Appropriate ASM Instance.

If you are using clustered ASM, you should first install the Oracle CRS software and then install ASM. If you are using clustered ASM on SPARC, you should also install the ORCLudlm package before installing ASM.

When you run Oracle Universal Installer, you have the option to configure and install ASM and create disk groups. For detailed information on installing and configuring ASM, see the Oracle documentation corresponding to the Oracle database version you are using.

When you create the same disk group with ASM on different cluster nodes, you must create the disk group one node at a time and dismount the disk group before creating the same disk group on another cluster node.

You should setup and configure the file system, where the ASM ORACLE_HOME reside before performing the ASM installation.
