I'm trying to install oracle 11g on AIX 6.1.

The install is failing stating that it needs 6,478MB of free space but df output below clearly shows it has 7183MB, what am I missing here?

Quote:

[FATAL] [INS-32021] Insufficient disk space on this volume for the selected Oracle home.
CAUSE: The selected Oracle home was on a volume without enough disk space.
ACTION: Choose a location for Oracle home that has enough space (minimum of 6,478MB) or free up space on the existing volume.

Oracle also use temp space in addition to final one.
Add space to the fs.

According to the Quick Install Guide:
Quote:

The following are the disk space requirements for installing Oracle Database 11g Release 2 (11.2):

At least 1 GB of disk space in the /tmp directory

The following table describes the disk space requirements for software files for each installation type:
Installation Type Requirement for Software Files (GB)
Enterprise Edition 6.40

As my /tmp was only 1GB in size I thought that might be the cause so increased it to 2GB but get the exact same complaint when running the install.

This appeared earlier in the outputQuote:

ORACLE_HOME /home/oracle/app/oracle/product/11.2.0/dbhome_1

So it's definitely referring to /home but this has more than the required space. How much free space should it have?

You need several GB more than the minimum, otherwise it will all fall over later anyway because of space needed in the Oracle Base for trace files, log files, audit records, and so on. I would give it a filesystem with at least 10GB. And then, where do you intend to create the database? And the Fast Recovery Area?

Isn't it usual for the database to be created under ORACLE_HOME? Otherwise I don't know. I know I'm demonstrating my noob credentials here but I'd never heard of a Fast Recovery Area before today. I'm entirely reliant on the documentation to get this installed and all I can find in the quick start guide is:

Quote:

Additional disk space, either on a file system or in an Automatic Storage Management disk group, is required for the fast recovery area if you choose to configure automated backups.

I've no idea how to configure automated backups and right now that's a far off problem as I can't even get the database itself installed. It doesn't indicate how much space this is likely to need, if it should be on another volume or the same volume... does anyone have any rules of thumb?

I was asking specifically about the Fast Recovery Area. Anyway, increasing the /home filesystem to 15GB (just over 12Gb free) got past that problem.

FRA size depends on what you want to do with it and depends on your database activity and so on.
FRA does not need (and should not in my opinion) to be in the same FS than Oracle binaries.
