Installing the Oracle Automatic Storage Manager

Edit online

The third and last step in the installation of Oracle RAC is to install the Oracle Automatic Storage Manager (ASM).

To install ASM, complete the following steps:
  1. Start the runInstaller program in the same manner as the RDBMS installation. However, the first selection is Configure Automatic Storage Manager (ASM). See Installing the Oracle relational database.
  2. Select the option to create a new diskgroup, which is a named group of shared disks.

    For this study, all the shared disks for data storage were put in one diskgroup, named disks1. The installer displays every possible partitioned DASD as a candidate for shared storage.

  3. When the disks are selected in Linux®, ASM is ready to take over their management.
Note:
  1. Selecting disks for shared storage for the database can be done after clusterware is installed.
  2. Additional disks can be added, at any time. To the user their storage appears as expandable storage, fully striped.
