Oracle^® MiniCluster S7-2 Administration Guide

Create DB Homes (CLI)

Create at least one DB home in each DB VM. You can create multiple DB homes, each with specific version of the Oracle Database.

1. Create DB home installations in each deployed DB VM.

   This command enables you to select the version of the Oracle Database that you want installed, then installs the DB software in the DB home directory that you specify. Homes are created in each DB VM.

   Respond to each prompt:

2. (If desired) Repeat Step 1 to install another version of the Oracle Database in the DB VMs.

   For example, if you originally installed Oracle Database 12c in /u01/app/oracle/product/12.1.0/dbhome_12c, you can then install Oracle Database 11g in another home, such as /u01/app/oracle/product/12.1.0/dbhome_11g.

   ---

   Caution  -  Wait until you see the message Database home installation succeeded before you repeat Step 1. Do not repeat Step 1 to install another version of the Oracle Database in the DB VMs until the process completes for the previous installation.

   ---

3. List the status of the DB homes.

   In this example, two DB homes are active in each VM.
