Distributed installation

[Former Member]

Hello,

I've got a problem with distributed installation of SAP systems. I've got 3 servers - one is dedicated for Oracle, two for application servers (systems DD1 and DD2). How to distribute services and databases in all these servers?

One of the main goal is that systems will see each other as an active servers (list of servers in transaction SM51).

As I understood I should have one SCS service on the globalhost. For example let's globalhost will be host with database. But how to set parameters in the profile default.pfl? How to set it for several systems? Can the name of instance will be different from other systems (DD1 and DD2) - for example DSC?

The next thing is Oracle. I think I should install two instances of Oracle, one instance for one system. But where to set ORACLE_SID in the Windows system?

So I think I should have one instance of SCS (common), two instances of database (everything can be on the one server); and two instances of CI on the two separate servers. Am I right? But how to set parameters?

I hope, somebody can help me - thank you.

Regards,

Michal

You can design this way

DB Server (Dedicated DB server for DD1 & DD2)

DD1 & DD2 (2 CI's on one system)

DD1 & DD2 (Application server for both)

Jacob,

But this way he can't see 2 application servers in SM51?

If this guy want to see 2 sys. in SM51 he need's only one CI.

Hello Hari,

thank you for your reply. That's a part of my question. How to set parameters in the default profile? For example in other installation I've got:

SAPSYSTEMNAME = DDS

SAPGLOBALHOST = ddsap

#----

---

1. SAP Central Service Instance for J2EE

#----

---

j2ee/scs/host = ddsap

j2ee/scs/system = 01

j2ee/ms/port = 3901

#----

---

1. SAP Central Service Instance for J2EE

#----

---

login/system_client = 001

SAPDBHOST = ddsap

j2ee/dbtype = ora

j2ee/dbname = DDS

j2ee/dbhost = ddsap

rdisp/bufrefmode = sendoff,exeauto

#----

---

1. SAP Messaging Service for ABAP

#----

---

rdisp/mshost = saperp

rdisp/msserv = sapmsDDS

rdisp/msserv_internal = 3920

#----

---

1. SAP Messaging Service for ABAP

#----

---

#----

---

1. SAP Messaging Service for ABAP

#----

1. SAP Messaging Service for ABAP

#----

SAPTRANSHOST = ddsapbe

But there are parameters which depends on instance (I think so) like:

j2ee/dbtype = ora

j2ee/dbname = DDS

j2ee/dbhost = ddsap

SAPSYSTEMNAME = DDS

and others...

What to do with these parameters? Should I split them into start or instance profile? I don't understand it exactly.

I understood that I should have one SCS instance for several CI instances if I would like to see all the systems in SM51 (?). Can SCS has different <SID> than other CI instances?

Michal,

In a distributed environment we install oneCentral Instance(CI) and additional Dialog instances(DI). If you install one CI and one DI you will see 2 application servers in SM51. If you want to install a DI, first install Oracle client and start installing DI, it will automatically get's it Profiles there is no need of changing any thing.

Try to be more clear about your scenario then i can help you.

Hari.

Hello,

What SAP software do you want to install ?

And with which configuration ? (Abap stack ?, Java stack, Dual stack )

2 Oracle instances : you want to install 2 SAP systems ?

You don't give enough information to get answers...

PS : People should understand before asking a question that they need to give info about their context. Nobody can guess what is obvious for the person asking the question !

Hello,

it should be abap+java stack, two SAP systems (DD1 and DD2) - mySAP ERP 2005.
