Sizing Disk Space for Oracle10g

Oracle says that about 2.5 GB of disk space should be reserved for the Oracle software on Linux.

When I did an Oracle 10g Release 1 (10.1.0.3.0) "General Purpose Database" installation (not including any software from the Oracle Database 10g Companion CD), the Oracle software used about 1.3 GB of disk space, and the preconfigured "General Purpose Database" (datafiles, etc.) used about 710 MB of disk space.

$ du -m -s /u01
1963    /u01
$ du -m -s /u01/app/oracle/oradata
720     /u01/app/oracle/oradata

If you also install additional software from the Oracle Database 10g Companion CD, then add at least 1 GB of free disk space.

So if you install Oracle10g Enterprise Edition and additional software from the Oracle Database 10g Companion CD, then you need about 2.5 GB of disk for the Oracle software. And if you also want to add a preconfigured database on the same filesystem, make sure to add another 1 GB of disk space.

NOTE: If you don't put Oracle10g on a separate filesystems, then make sure the root filesystem "/" has enough disk space. You can check the free space of the root filesystem with the following command:

df -h /
