SAP distributed system on linux installation

[former_member459694]

Hello All,

I am now installing sap erp ehp7 system on redhat linux, with installation mode: Distributed System.

ASCS instance has been installed, after that I export /sapmnt/SID/exe, /sapmnt/SID/profile, /sapmnt/SID/global from ASCS instance host, and mounted them one by one on database instance, and now I am installing database instance, everything goes well except for the last step -  brconnect to update statistics, this was due to a permission issue, however when I try to change owner of those files, I found all global host files and files under /usr/sap/SYS has ownership "nobody" and group "nobody", and I can not change them.

Do you have any idea how to solve this? I know for windows installation of Distributed system, a domain installation is mandatory, is it also obligatory for linux installation?

Thanks a lot.

For the nobody user/usergroup please check the last post in the below link. Or you could also have your UNIX team to have a look at the NFS config.

linux - Why user becomes nobody? - Super User

Can you provide the exact error you have received?

Hi,

You could have mounted /sapmnt/<SID> from CI node to DB node and install oracle client on both the nodes DB node and CI node.

Second thing you should check how are the mount points create and the access given to which user.

 I found all global host files and files under /usr/sap/SYS has ownership "nobody" and group "nobody", and I can not change them

Can you please confirm that you are running the installation via root.

Would suggest you mount the /sapmnt/SID properly.

Please read the guide propley.

Thanks

Hi Abrol,

Thank you for your reply.

I strictly follow the installation guide "Installation Guide SAP Systems Based on the Application Server ABAP of SAP NetWeaver on Linux : Oracle Using Software Provisioning Manager 1.0"

First I installed ASCS instance on host A, and now I am installing database instance on host B (problem here), and later I will install CI on host A.

I have following questions:

1. to install Distributed system, is it obligatory that the linux operating system to be in a domain enviroment??

2. I exported /sapmnt/SID/exe, /sapmnt/SID/global, and /sapmnt/SID/profile via NFS from ASCS host, and then created those folders on the database host, and mount those three folders one by one, everything is doing with root, and following the sap official guide.

Please kindly advice, thanks a lot.

Hi,

Can you please explain the first question .

2. I exported /sapmnt/SID/exe, /sapmnt/SID/global, and /sapmnt/SID/profile via NFS from ASCS host, and then created those folders on the database host, and mount those three folders one by one, everything is doing with root, and following the sap official guide.

You should read section 4.2 in the installation guide.

.4.2Creating Operating System Users and Groups

Page 40.

I only see the issue looks to be with the user account .

can you go in /sapmnt/SID and do ls -ltr and see the permission.

We usually create the user account on all the host so that we have specific uid and gid on respective hosts.

Thanks
