Two NetWeaver ABAP in one server

[Former Member]

Hello,

Currently in our SUSE server exists SAP NetWeaver ABAP server. It's with a single disk, meaning instances, transport directory, oracle soft. and data exists there.

A second NetWeaver is to be installed in the same server, but in the newly attached disk (partition). All new instances, new transport directory, oracle soft and data (one more RDBMS) should reside there.

The installation guide states that I need to set up something manually, because it does not prompt for some things and would install in the 1st partition:

• The figure below assumes that you have set up one file system for the SAP system mount directory <sapmnt> and one file system for the /usr/sap directory. However, you have to decide for which directories you want to set up separate file systems. If you do not set up any file system on your installation host, the installer creates all directories in the root directory (/ ) . The installer prompts you only for the <sapmnt> directory during the installation.
• Set up the required file system nodes for the Oracle database before the installation.

How do I create these file systems and not mix them up with the existing ones?

Thanks!

Hi Nerijus,

Technically it is possible to install more than one ABAP instances on a single server.

Point to take care are

1) usr/sap/trans should be made different

2) Need to have different file systems like /oracle/SID

Hope this helps.

Yes, I know it's possible, but what should be done prior to running SWPM installer?

As I understand I need to create file systems manually somehow, how do I do it?

"If you do not set up any file system on your installation host, the installer creates all directories in the root directory (/ ) . "

"Set up the required file system nodes for the Oracle database before the installation."

Hi Nerijius,

For below requirement

"If you do not set up any file system on your installation host, the installer creates all directories in the root directory (/ ) . "
"Set up the required file system nodes for the Oracle database before the installation."

You need to ask OS administrator to help you in creating below file systems

/usr/sap/<SID>

/sapmnt/<SID>

/oracle/<SID>

Additionally if the other system is not part of same landscape you need to create a new transport filesystem  /usr/sap/trans_SID

Hope this helps.

Thank you, but these need to be created in a newly attached partition, do you know how it should be done?

Hello

You basically need to create separate file systems for the new SAP system.

How the file systems can be created using the newly added partition is an OS related question.

But for your information you can refer to this article.

Linux: How Do I Create a New ext3 File System If a Disk Was Added To The Server / Desktop?

Once the file systems are created and when you start the installation you can provide the newly created file systems for Oracle installation and SAP installation.

Thank you for that.

But as the document states "installed only lets to choose <sapmnt>" and i choose /2ndpartitionFolder/, wont the installer just put everything under /usr/sap/ (which is the 1st partition, and not the freshly added)?

[Reagan · Accepted solution]

Create new file systems called /sapmnt/SID and /usr/sap/SID for the second system.

Start the installation.

Ok, that seems more helpful, maybe you know exact console commands which are needed to be executed? for example to create file system " /usr/sap/SID">?

You should get the OS specialist to do that for you.

A quick search on Google have me these.
