SAP PO 75 Distributed Installation on Linux x86 – Part3

In the previous blogs Part1 and Part2 we have seen downloading the Stack XML and installing SCS instance. Now lets dive into Part3 and see how to install DB server.

Assumptions:

/sapmnt directory is mounted on pofdb00
SCS Instance is successfully installed.
Oracle Server and Client Software are downloaded.

Install DB Server:

1. Login into pofdb00 with root and goto root directory. Once we are in root create four directories like shown below. Once we create these directories we will add the mounts from SCS in /etc/fstab. Given below are the screenshots:

2. Once we added mount it using command mount -a and check they are successfully mounted using df -k.

3. Run SWPM using the command ./sapinst -nogui &

4. Login with root user and pwd in the next screen.

5. Once you logged in we are at home page of SWPM screen.

6. Now go to path: Software Provisioning Manager 1.0 SP22 –> SAP NetWeaver 7.5 –> Oracle –> Installation –> Optional Standalone Units –> Process Orchestration –> Distributed System –> Database Instance

CAUTION: Be very careful to select right DB and right option.

7. Select Next in above screen. If we say Typical in next screen SAP will picks default setting. But we would like to use Custom in my landscape, so select Custom and click on Next.

19. Specify the OS username for Oracle.

20. Specify sidadm password, userid and login shell in the below screen else it will give you by default the master password.
