When complete, run e2fsck on your logical volume, resize your file system using resize2fs , and mount your
file system:

[root@cm01dbm01 ~]# e2fsck -f /dev/VGExaDb/LVDbOra1
e2fsck 1.39 (29-May-2006)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information

[root@cm01dbm01 ~]# resize2fs -p /dev/VGExaDb/LVDbOra1

[root@cm01dbm01 ~]# mount /u01

An alternative to extending your /u01 file system is to NFS mount external storage and symbolically link your
Oracle 11gR2 diagnostics directories for each of your database to external storage.

■ We recommend installing new Oracle Homes in a subdirectory under /u01 rather than using available
disk storage to create a new volume and mount point. Changing the default file system layout on Exadata can lead to
challenges performing LVM-snapshot-based recovery and compute-node reimaging; both of these features will still work
with a custom file-system layout, but they introduce risk and additional steps.

Note

Next, download and stage the Oracle 11gR2 software from My Oracle Support or the Oracle Technology Network
(OTN). Installing Oracle on Exadata is similar to installing Oracle on non-Exadata, and you will need to stage your
installation software on a directory on one of your compute nodes.

■ When Oracle aCS performs the initial Exadata installation, the Oracle 11gR2 binaries are pre-staged on
/opt/oracle.SupportTools/onecommand<version> and Step 19 of the installation process uses the Oracle installer
to install your first Oracle Gi and RDBMS Home on your compute nodes. this installation uses a seeded response file for
input parameters based on your configuration worksheet. you can attempt to adjust this response file and run the
/opt/oracle.SupportTools/onecommand/tmp/dbm-dbsw.sh script, which is called from Step 19 of the installation
process, but in many cases organizations patch and/or upgrade their binaries over time. We recommend downloading
current, supported software from Oracle and manually launching the installer to complete your installation.

Note

After downloading, staging, and unzipping your software, log in as your Oracle software owner, navigate to the
database directory, and launch runInstaller to install your new Oracle RDBMS Home.
