Separate Dual Stack

[Former Member]

Good Day:

I need a recommendation, i need separate the Java system from a dual stack system, this not is the problem, the problem are 3:

1. Is a CRM System. (What i need look between systems to preserve the configurations and communications between systems)

2. Is a distributed system, the stack Java+ABAP is in one physical Hardware and the data base is in another, the destination for Java is another physical Hardware.

3. Taking on mind the point 2, is necessary install in the same DataBase.

Taks a lot for your answer!

Best regards!

Dear Costumer,

Currently, it is not possible to split an ABAP+Java system into two

separate stacks.

A tool to do that is still being developed, however, we cannot provide

an estimate time of arrival.

Therefore, the only option would be:

1. Deinstall the Java Stack first from the system (as described

per installation guide)

2. Perform a system copy of the ABAP only system if necessary

3. Install the Java Stack seperately on a new hardware

Unfortunately at the moment there is no tool available to transfer

the settings and the content of the Java Stack to the newly installed

Java system. You would need to set-up the newly installed java as you

had it on the source system and apply any java support packages to

match your sp level on the source.

I hope the above helps you.

Please let me know in case of any questions.

Kind Regards,

SAP Active Global Support, Business Suite & Technology

MY MESSAGE TO SAP

Good day:

Context:

We update our version of SAP CRM 2006 and CRM 7.0 EHP1 with Netweaver 7.2 so far everything

is correct.

Technical Environment:

SAP EHP 1 for SAP CRM 7.0 is on SAP NetWeaver 7.02 and installed on ABC-Server on dual-

stack, a the second server DEF-Server is the database is required only to separate

instances of the ABAP-JAVA, Java go to the server GHI-Server, but the database is not

split.

Problem:

Once make the system upgrade, se second step is splitting the Dual-Stak, in this step we

don't found a tool for make the split, the cuestions are three, 1) exist a tool for make

this task? 2) if not. how we can make this? 3) this is supported by SAP

under what

specifications.

we try to make a split by the stardart sapinst but when we try to import the data base the

system say what this is not support on the database but is the same database engine

(Server).

Normally this task is simple but the option, system copy and extraction, for a new

installation and the creation of the other system with individual database is not possible

Hi,

SAP has recently introduced dual stack split tool which takes care of most of the configuration while splitting this tool. It was planned to released in November. But I am not sure whether it is released or not. Have a look on below link:
