Hi,

What are all the mount points shared to oracle database from the Central instance server in case of distribution installation with NW 7.45/ 7.50

/sapmnt/SID

/usr/sap/SID - Is this really needed?. If mounted, problems could arise with database installation?

I appreciate all your inputs..

Thanks in advance

Hi Daniel,

First thing - Oracle mount points means *sapdata* folders and the Oracle home.

/sapmnt/SID, /usr/sap/SID are SAP mount points which contain application specific things like executables (Kernel), Profiles, Instance directory etc..

/sapmnt is a shared mount point exported from your CI to apps servers so that all Apps will share Kernel, profile directory, TNS_ADMIN folder and other things which are in common.

/usr/sap/SID is a local directory exists on each apps server to have their own instance data.

/oracle/client is again a local directory you have everywhere, Client takes care of connectivity between application layer and the database layer.

If you want to install additional apps sever - you need /sapmnt/SID exported from CI, /oracle/client/* folder to extract client, /usr/sap/SID to have local instance

Hi Daniel,

/usr/sap/SID is store sap kernel, so this is needed. However this should not affect oracle database server.

Best regards,
James

Hi, No /usr/sap/SID is local directory, you should not share it.
Just /sapmnt/SID.

BR, Sergo.
