Introduction

The dual-stack split procedure got integrated into

software provisioning manager 1.0 –

the procedure is no longer available as standalone tool

Overall, software provisioning manager 1.0 offers relevant procedures

required to install, copy, and transform SAP systems in your landscape

Dual-stack vs. single-stack SAP systems

Definition – what is a dual-stack system?

Definition: SAP system that contains both SAP NetWeaver® Application Server ABAP and Java with following

characteristics:

One common SAPSID

One common startup framework

One common database

Examples:

SAP NetWeaver BW

with SAP BEx Web

(optional dual stack)

SAP NetWeaver

Portal (Java

single stack)

SAP ECC

(ABAP

single stack)

SAP NetWeaver PI

(mandatory

dual stack) Capability based on ABAP

SAP’s approach for better managing a system landscape Overview of general approach

• Ease landscape modeling

• Automate software logistic

processes by applying clear rules

• Offer tool support for changing

certain landscape layouts • Balance scope of different deployment options

• Ensure predictable landscape behavior

• Offer setups by selectable landscape pattern

• Provide best practice setups

• Reduce complexity of landscape planning

• Unveil landscape behavior of products

Dual-stack vs. single-stack SAP systems General recommendation

SAP provides clear recommendations for customers how to deploy

different SAP NetWeaver capabilities in a solution landscape

Based on SAP’s product strategy and considering experiences from existing

customer landscape layouts

General recommendation:

Deploy ABAP and Java in separate systems (where possible)

Aspect Dual Stack Single Stack

Setup & configuration effort

Backup & recovery effort

Sizing

Monitoring

Security

Administration / software maintenance

Flexibility

Scalability

Availability

Advantages for dual stack only in some areas of lifecycle management

Certain benefits can also be achieved with other means

For other areas, tools & procedures provided on landscape level

Altogether, only some goals reached on expense of other areas Conclusion

Dual stack vs. single stack SAP Business Suite

As of SAP Business Suite 7, you can no longer install dual-stack application systems

SAP Business Suite 7 comprises SAP ERP 6.0 EHP4, CRM 7.0, SCM 7.0, PLM 7.04, SRM 7.0

SAP Business Suite 7 i2011 is last SAP Business Suite release with dual-stack support –

no upgrade/update of dual-stack SAP Business Suite systems to higher releases!

SAP Business Suite 7 i2011 comprises SAP ERP 6.06, CRM 7.02, SCM 7.02, PLM 7.06, SRM 7.02

SAP NetWeaver systems that have SAP Business Suite components deployed might also be treated as

SAP Business Suite systems in this regard (for more information, see SAP Note 1816819) – for example,

an SAP NetWeaver Portal system with SAP Business Suite business packages deployed and set up as

dual-stack could not be upgraded to SAP NetWeaver 7.3x

Dual stack vs. single stack SAP NetWeaver

As of SAP NetWeaver 7.0 Enhancement Package 1

(EHP1), you can no longer install dual-stack

application systems (apart from SAP NetWeaver PI)

Dual stack

ABAP only

Java only

SAP NetWeaver 7.31 is last release with support of optional dual-stack

systems – no upgrade/update of optional dual-stack SAP NetWeaver systems

to higher releases (such as SAP NetWeaver 7.4)!

Exceptions:

Workarounds to install dual-stack SAP NetWeaver BW 7.0 EHP1 system – see SAP Note 1181025

Dual-stack SAP NetWeaver PI systems remain supported – for more information, see next slide

SAP NetWeaver systems with usage type Mobile Infrastructure (MI) are not supported by dual-stack split

procedure

– SAP NetWeaver Mobile Infrastructure is not part of SAP NetWeaver 7.31 or SAP NetWeaver 7.4

– Therefore, dual-stack deployments of SAP NetWeaver Mobile Infrastructure cannot be upgraded anyhow, but have to

be migrated – for more information, see the Migration Guide – SAP NetWeaver Mobile

Dual stack vs. single stack SAP NetWeaver PI

SAP NetWeaver PI:

Dual-stack SAP NetWeaver PI systems remain supported, also in releases higher than

SAP NetWeaver 7.31

Starting with SAP NetWeaver 7.3, there is additional Java-only offering for main process

integration capabilities called Advanced Adapter Engine Extended, covering ~95% of a

classical SAP NetWeaver PI dual-stack environment, feasible to most use cases –

customers are recommended to migrate SAP NetWeaver PI content to single-stack objects

– Due to harmonized process orchestration stack (SAP NetWeaver PI and SAP NetWeaver BPM

running on same Java instance), many of ccBPM features in SAP NetWeaver PI can be expressed

using SAP NetWeaver BPM capabilities instead

– For more information, see the roadmap document SAP NetWeaver Discontinues Dual-Stack

For more information about the migration, see:

– SAP Help Portal: Migration of Dual-Stack Configuration Objects (“Classical Scenarios”) to Integrated

Configuration Scenarios (Java-Only)

stack and SAP Directory Content Migration Tool

Dual-stack vs. single-stack SAP systems SAP Solution Manager and SAP HANA

SAP Solution Manager 7.0 and 7.1

systems are dual stack

New installation, update and upgrade

of SAP Solution Manager systems to

these releases still supported

SAP HANA does not support dual

stack

Dual-stack split is prerequisite for

migration of existing dual-stack

systems to SAP HANA

Dual-stack vs. single-stack SAP systems Dual-stack split procedure

Post-split

activities

Re-configuration, such

as of technical

connectivity between

SAP NetWeaver ABAP

and Java system –

automated for certain

use cases

Removal of Java

stack from

source system

Removal of Java-

related SAP system

information within

source system

Can also be used to

only remove Java stack

Separation of

Java stack

Separation of Java

stack of dual-stack

source system into new

SAP system

1 2 3

Status Quo:

Existing optional dual-stack systems still supported as an exception at least in their current release

SAP wants to support customers to get aligned with the recommended landscape setups

SAP is offering a procedure for changing the landscape layout for certain use cases
