linux file system arrangement with symbolic links supported by SAP?

[Former Member]

Hello Sap experts,

We are setting up a distributed SAP production environment. Application servers on windows and the sap database will be on linux servers (Oracle RAC). It is Netweaver 7.0 (2004s) and Oracle 10g.

DEV and QA are installed on the same linux servers. PROD will not share it's servers.

The standard linux SAP file system layout has everything installed under

/usr.

But in our case the available file systems are these:

/u01 (for Oracle software)

/u02 (For DEV SAP installation and database files)

/u03 (For QA SAP installation and database files)

For each Sap installation and database we use symbolic links that point to the relevant folder in the file system.

Specifically, where you might expect to see /usr/sap/QE1 and /usr/sap/DE1

we have the following under /usr/sap

lrwxrwxrwx 1 root root 11 May 26 2009 DE1 -> /u02/SAPLOC

lrwxrwxrwx 1 root root 11 May 26 2009 QE1 -> /u03/SAPLOC

The question, is this file system arrangement supported by SAP?

Many thanks in advance,

Best regards,

Hi Manfred,

my systems use quite a similar layout, but I have them located on NFS. This allows me to "move" my SAP instances between physical hosts just by creating symlinks on the target servers.

Regarding your question, I wouldn't find an argument, why symlinks shouldn't be supported. I know several customers as well that use symlinks in the SAP directories ... Just take care that you doesn't link to non-existing folders

Thanks,

Hannes
