EHP4 Dual stack

[Former Member]

hi guys,

we plan to upgrade Enterprise Dual stack(ABAP+JAVA) System to EHP4 system.

In EHP4 upgrade document it says, No dual stack supported for EHP4 installation..was that mean

only for Installation or upgrade too.

Seperate SID is required for EHP4 system after upgrade? Please confirm.

thanks

EHP4 upgrade supports dual stack... Also, I am not able to understand by seperate system id..

During installation of EHP4, ABAP and Java asks for seperate SID. it does not accept single SID for Both as dual stack system.

so wondering how Dual stack can be upgraded to EHP4 with single SID.

we have upgraded our landscape to EHP4 but we did not faced any problem related to SID and in our landscape ABAP and Java has same sid...

thanks sunny

hi jaichan,

yes, you are right ..For new installation of SAP ERP to EHP4 level, you cannot install dual stack system..i have read in sap note 855534..please find below the extract from this note:

As of SAP Business Suite 7, you can no longer install Dual Stack Application Systems (ABAP+Java).

If you want to use both SAP Business Suite ABAP and Java Components in your system landscape, you have to proceed as follows:

1. Install a separate ABAP-based SAP Business Suite system.

2. Install the required Java components in a separate Java-based SAP system.

3. Configure the connection of the Java-based SAP system to the ABAP-based SAP Business Suite back-end system.

The SAP Business Suite 7 comprises: EHP4 for SAP ERP 6.0, SAP CRM 7.0, SAP SCM 7.0, SAP PLM 7.0, SAP SRM 7.0

As of now you will find the latest recommendations at a central place in SDN:

https://www.sdn.sap.com/irj/sdn/landscapedesign -> Distribution Models

You will also find information about the deployment of SAP NetWeaver usage types and the SAP Business Suite there.

but you can upgrade your previously installed SAP ERP dual stack system without having seperate SID's thing...

We have upgraded around 50 of our systems without any problem

thanks sunny

Hi,

Thanks for this interesting and very new SAP note !

At least, SAP recognizes that the dual stack concept was a very bad idea...

Too bad for the customers who made the "wrong choice" a few years ago.

If I understand well only BI and SOLMAN are supposed to keep the dual stack concept as mandatory.
