Performing SAP system copies automatically
A system copy can be created either with SAP transactions (R3trans, from R4.6C SAPinst) or at file and database level. Costs and effort increase with the size of the system and the requirements for availability and data protection. In addition, administrative rework is often necessary, starting with the system name and extending to printers and interfaces.
SAP production system copies are created for a variety of reasons, including: - Generating a new non-production system for short- or long-term use - Updating an existing non-production system An SAP system copy is called homogeneous if the source and target operating and database systems are identical. If this is not the case, the system copy is considered heterogeneous. Heterogeneous system copies or platform migrations are not supported by the HP StorageWorks System Copy software for SAP and are therefore not discussed further in this document. In addition, this document deals exclusively with system copies for non-production target systems. Overview of a homogeneous system copy Figure 1 shows copies of an SAP production system that are created for non-production systems. Some copies are short-term (ad hoc) in nature, while others are intended for long-term use. Note that when a long-term system is created from a system copy, a system copy may be needed for updates later in the system's life cycle. This adds the latest transactional data from the original production system. Given their particular importance, this document focuses on scenarios with system copies created for updates. Figure 1: Overview of scenarios with homogeneous SAP system copies Scenario with system copies for updates In order to meet constantly changing business requirements, a production system must be continuously developed and adapted after the initial installation. To do this, you need development, consolidation, and quality assurance (QA) systems that can provide the production system with the appropriate updates as SAP transports.
SAP Landscape Copies
An alternative to this is a refresh using a client copy. The test environment will then be missing audit documents, among other things, but the development objects will remain untouched. The client copy only works from a running SAP system, but it burdens the system with database queries and transfers data more slowly than a system copy. The affected client is not available during the copy process. Since there are no options within the client to select what all should be copied, the runtime is often unacceptable.
A non-production SAP system should also have the same repository status as the source system, regardless of the data transfer method chosen for the refresh. All the data that makes up an SAP system is stored in the repository. This includes, among other things, the definitions for the database fields and tables for master and transaction data.
With "Shortcut for SAP Systems", tasks in the area of SAP system copying are simplified and can also be automated via the command line interface.
With the definition of package groups, the parallel processing of packages can be configured beyond the definition of the order: All defined groups run in parallel to each other.
In addition, the data still has to be imported from the production system, for example via a client copy.
