Distributed installation, sharing of profiles: Linux

Hi readers, in this post we will dive into sharing of profiles among Linux hosts while performing distributed installation.

In a distributed setup in which ASCS, DB and PAS are to be installed on Linux OS, we will have to share profiles from the ASCS host to the DB and PAS hosts. For this we need to perform the following steps.

First we pass the path along with the permissions by adding the required lines inside exports file in /etc directory, in the ASCS server.

For eg:
/sapmnt/<SID>/profile <target server name>(rw,no_root_squash)
/sapmnt/<SID>/exe <target server name>(rw,no_root_squash)
/sapmnt/<SID>/global <target server name>(rw,no_root_squash)

The above parameter depends on which files are to be shared, with the exe folder being optional. As the kernel related files can be provided manually during SWPM run. In <target server name> we give PAS and DB server names.

NOTE:
The SWPM run for installation of DB instance can be run from any one of the hosts. This is because the SWPM for DB instance just creates the schema user along with changes related to DB host in default profile. The only thing to be careful is about giving the correct DB server details during SWPM for DB instance installation. The SYSTEM users of DB gets created when we initially install the HANA DB using hdblcm executable in DB host.
