Difference between directories

[former_member759680]

Hello,

Could someone explain me in details, the difference between the following directories in Unix

1. /sapmnt/DEB/exe

2. /usr/sap/DEB/SYS/exe/run (I think its the same as /sapmnt/QEB/exe, but why have 2 same directories?)

and

3. /usr/sap/DEB/DVEBMGS00/exe

Thanks.

1 and 2 are related to the kernel usually /usr/sap/DEB/SYS/exe/run and /sapmnt/DEB/exe are binded by a softlink basically everytime that you update /sapmnt/DEB/exe the contents of /usr/sap/DEB/SYS/exe/run get updated... is the same as a share in windows.

3. does not exist. and if it does someone put that directory in the incorrect location.

But Juan,

I see /usr/sap/DEB/DVEBMGS00/exe in all of the systems in my landscape.

whats the version of SAP you're running and under what flavour of Unix?

In any case it must be another softlink... .

I have a 4.7 in AIX 5.3 without that exe directory there.... anyhow as i said before it must be another softlink

Juan,

On a CRM 2007 system on Windows 2003, I've got a directory

D:\usr\sap\DCL\DVEBMGS08\exe

This the directory from where executables are actually loaded at runtime.

I have also

D:\usr\sap\DCL\SYS\exe\uc\NTAMD64

When starting the system, the main executables are copied from

D:\usr\sap\DCL\SYS\exe\uc\NTAMD64 to D:\usr\sap\DCL\DVEBMGS08\exe

Regards,

Olivier

As far as I'm aware In Unix the executables run from /sapmnt/<sid>/exe and distributed to /usr/sap/<sid>/sys/exe/run via softlinks, so i presume /usr/sap/<sid>/<instance>/exe is another softlink... to check that just do an ls -la at the /usr/sap/<sid>/<instance>/ to see if the exe directory is actually a directory or a softlink.

In Unix, /usr/sap/<sid>/<instance>/exe is not a softlink like /usr/sap/<SID>/SYS/exe. But the files are dynamically loaded from /sapmnt/<SID>/exe during runtime.
