What is SAP NetWeaver Landscape Virtualization Management (LVM)?
- SAP NetWeaver Landscape Virtualization Management software is a management tool that enables the SAP basis administrator to automate SAP system operations including end-to-end SAP system copy/refresh operations
- The software is shipped as an add-on to SAP NetWeaver 7.3 (Application Server Java) and is available in two additions: Standard Edition and Enterprise Edition.
I would like to take a look at the Product, are there any demos available ?
- Yes, there are several demo videos available on the SAP Technology youtube channel
- SAP NetWeaver LVM - YouTube
Is LVM a licensed product? If yes, how does the licensing model work?
- Yes, SAP NetWeaver Landscape Virtualization Management software is a licensed product and the product is available in two editions: Standard edition and Enterprise edition.
- Standard edition is available to all SAP customers with at least one active SAP application license and has no license cost associated with it. The customer will have to obtain a license for Standard Edition but, do not have to incur any additional cost..
- Enterprise edition is available to all SAP customers as a separately licensed product. Please contact your SAP Account Executive or Sales Representative for further details.
Is the license model going to change with the next version of LVM ?
- No, there are currently no plans to change the license model of LVM
What is the value proposition of LVM and what are the business benefits ?
With SAP NetWeaver Landscape Virtualization Management software (LVM), you can simplify and automate the management and operations of your SAP systems running on traditional, virtual or cloud infrastructures.
- Greater operational continuity through centralized management, visibility and control of your entire SAP landscape using a single console.
- Reduced time, effort and cost to manage and operate your SAP systems through automation of time-consuming basis administration tasks.
- Increased operational agility through acceleration of application lifecycle management operations and fast response to workload fluctuations.
Does (LVM) replace SAP NetWeaver Adaptive Computing Controller (ACC)?
- No, SAP NetWeaver Landscape Virtualization Management software (LVM) is a new product which is generally available for SAP customers since June 2012. The new product is positioned as a management tool for SAP basis administrators and inherits all the ACC capabilities in addition to offering more advanced automation capabilities such as, end-to-end automation for SAP system clone/copy/refresh operations, automatic capacity management for SAP systems, landscape reporting and landscape visualization etc.
- All customers using ACC have the option to move to the Standard Edition of LVM without paying any license fee. The Standard Edition includes all the ACC capabilities and more. ACC 7.3 is the last release of that product and no new feature development is planned. Customers can continue to use ACC. However, we do recommend switching to LVM.
I am an existing ACC customer, how will I be supported in the future and how can I make the switch to LVM?
- ACC customers can continue to use the product and will be supported as part of their ongoing SAP NetWeaver support. However, we strongly recommend switching to SAP NetWeaver Landscape Virtualization Management (LVM) as it has taken over and continue all use cases from ACC.
- Switching from ACC to LVM is really simple and straightforward. All you have to do is export your existing ACC system configuration using export/import functionality in ACC and import it back into the LVM system using the same export/import feature available in LVM. As a best practice, SAP recommends installing a fresh LVM system and migrating the configuration from ACC to the new LVM system as explained above.
When will the next version of LVM be released ?
- LVM 2.0 is GA since Oct. 21, 2013
- For upcoming releases, please refer to our Roadmap presentation.
Are there any prerequisites for using LVM ?
- Yes, there are certain prerequisites for using LVM as it consists of several software components.
- The LVM software itself is shipped as an add-on to SAP NetWeaver (Application Server Java) and the minimum requirement is SAP NetWeaver 7.30 SP03 or higher (Application Server Java – “basic” usage type). Please check SAP Note 1527538 for further details.
- Depending on the product edition that you are using (i.e. standard or enterprise edition) and the product functionality that you would like to use, there are certain additional components required.
- The minimum dependency for managed systems is the SAP Host Agent, which must be running on each managed host (both SAP as well as non-SAP systems require SAP Host Agent for them to be managed via LVM).

What is the relationship between SAP Solution Manager and LVM? Are there any dependancies between these two products?
- SAP Solution Manager addresses Application Lifecycle Management for SAP systems (ALM). SAP NetWeaver Landscape Virtualization Management software enables running SAP systems on virtualized and cloud infrastructures and addresses infrastructure layer complexities. In addition, SAP NetWeaver Landscape Virtualization Management provides additional capabilities such as a framework for automated system copy/refresh and automatic capacity management which deal with the complexities of both the infrastructure and the applications through a single tool.
Can I run LVM as an add-on to the SAP Solution Manager Java instance ?
- No, this is not possible. LVM runs as an add-on on top of SAP NetWeaver 7.3 (Application Server Java) and the minimum requirement is SAP NetWeaver 7.30 SP03. Since, the latest release of SAP Solution Manager (i.e. SAP Solution Manager 7.1) runs on an earlier release stack of the Application Server Java Furthermore, even if this technical restriction is resolved in future, we would not recommend running LVM and SAP Solution Manager instances on the same host as part of best practices. Running both of these systems in the same host may cause performance degradation and moreover, in case of a system performance issue, it would become very difficult to diagnose and troubleshoot the root cause.
Does LVM integrate with SAP Test Data Migration Server (TDMS) ?
- No, currently there is no standard integration available between LVM and TDMS. However, TDMS compliments the use case of LVM and could be used in parallel to LVM. . TDMS offers data extraction of SAP business data and data scrambling which can be executed on SAP system copies that have been produced via LVM. Currently, we are evaluating various integration scenarios between LVM and TDMS and if something is available in future, we will update the product roadmap and communicate the same to our customers. We are looking into extending the SAP system copy workflow in LVM so that TDMS could be triggered as an optional step in one of the future releases of LVM.
Can I manage and monitor non-SAP Systems with LVM? If yes, what functionality is provided by LVM for management of non-SAP systems?
- Yes, LVM supports the management and monitoring of non-SAP systems and applications and this capability of LVM is called “custom services”. Technically, any application that can be detected as a service running an operating-system can be detected and managed by LVM
- LVM provides the following functionality for non-SAP systems (some examples of typical non-SAP systems would be middleware systems like Tibco/Biztalk, non-SAP data warehousing solutions etc.):.
- Performing basic monitoring and management of non-SAP systems such as, starting or stopping a system, collecting basic monitoring data such as CPU usage, memory usage, running state etc.).
- Performing mass-operations on non-SAP systems such as, mass-start or mass-stop).
- Configure Inter-System Dependencies (ISD) between SAP and non-SAPsystems:
Does LVM support management of SAP Sybase based systems?
- Yes. It is possible to manage SAP Sybase ASE based systems with LVM 1.0 SP5 onwards - including SAP System Copy operations. This requires the latest version of System rename. (system rename SP02 part of SAP SL Toolset)
Does LVM support management of SAP HANA based systems?
- Yes. It is possible to perform the basic operations (start/stop/monitor) for SAP HANA systems with LVM 1.0 SP04 onwards.

Where can i find more information on the Post Copy Automation for ABAP ?
My BDLS (logical system name conversion) takes forever, can you help me ?
- Yes. Even though we use the SAP standard BDLS functionality we have optimized it in several ways.
As you probably are aware, the normal BDLS is a single task, which means everything is sequential.
With the LVM PCA task list, we enable parallel processing with up to 26 tasks, which already speeds up things
significantly. In addition it is possible to convert multiple logical system names in one run.
The second major point is, that the standard BDLS goes through every table, independently if a conversion is needed or not.
We address this with a a preparation task. This task runs before the copy and actual conversion, scans all
the tables and creates a list of the tables that actually need a conversion. This list is then read after the copy
and only those tables that really need a conversion are being processed.
These features of the LVM ABAP Post-Copy Automation lead to significantly reduced runtimes.
Which stacks are supported by LVM for End-to-End automated system clone/copy/refresh (including System Rename and PCA) ?
Yes (workaround with manual steps available, see sectionJava System Refresh Workaround below)
No (see section Notes on Dual-Stack below)
No (see section Notes on Dual-Stack below)
NOTE: See SAP Note 1527538 for details on which SAP NetWeaver versions are supported.

Notes on Dual-Stack
Mandatory dual-stack systems (such as SAP NetWeaver Process Integration or SAP Solution Manager) are not supported by system copy/refresh of SAP NetWeaver Landscape Virtualization Management today.
For optional dual-stack systems (such as SAP NetWeaver Business Warehouse systems with BI Java), see the following best practice to use SAP NetWeaver Landscape Virtualization Management for copying or refreshing them:
· General recommendation: use the dual-stack split procedure to change the layout of your optional dual-stack systems to single stack
· SAP communicated to discontinue optional dual-stack systems with higher releases than SAP NetWeaver 7.31 and SAP Business Suite 7i2011. As a result, by splitting your optional dual-stack systems, you are prepared for future updates/upgrades to releases that do no longer support optional dual-stack (such as to SAP NetWeaver 7.40). You profit from the benefits that single stack deployments offer, such as higher flexibility, availability and scalability. Customer feedback shows that the dual-stack split procedure is easy, fast and reliable. For more information, see the dual-stack page in SAP Community Network at: http://scn.sap.com/docs/DOC-25162.
· After the split, you can profit from all the benefits SAP NetWeaver Landscape Virtualization Management is offering in the area of system copy and system refresh, as outlined in SAP Note 1527538.
· Reasonable alternative: un-install and re-install the Java stack of dual-stack SAP NetWeaver BW systems
· If you are using the Java stack of a dual-stack SAP NetWeaver BW system for BI Java only, it might be a reasonable procedure to un-install the Java stack and perform a new installation of a stand-alone BI Java system from scratch. For more information, see the SAP NetWeaver BW landing page in SAP Community Network at: http://scn.sap.com/docs/DOC-785 .
· After the un-installation, you can profit from all the benefits SAP NetWeaver Landscape Virtualization Management is offering in the area of system copy and system refresh, as outlined in SAP Note 1527538
· Possible exception: stay with dual-stack systems
· If you decide to keep the dual-stack layout for your optional dual-stack systems, you cannot profit from the benefits SAP NetWeaver Landscape Virtualization Management is offering in the area of system copy and system refresh as of today.
