The system copy
DB-specific methods: - for DB-homogeneous system copies - no Unicode conversion possible!
Renaming and restoring the target system database - adjusting file system permissions. Renaming, recovery and startup of the target system database.
Shutting down and copying virtualized systems, such as VMware instances, requires just a few mouse clicks. VMware is suitable for running multiple training, development and test environments on one physical system. Larger productive systems, on the other hand, are not so easy to virtualize. If users have to shut down the productive system during the copy, the runtime of the operation or the unavailability of the productive system becomes a critical factor.
Job logic instead of customizing
One of the most common methods of creating an SAP system copy is to use SAP's own tool "BR*Tools". This tool provides the ability to create a backup of the database, which can then be used to restore the system. It can also be used to export certain data from the database and import it into another system.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
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.
Tools such as "Shortcut for SAP Systems" are extremely useful in SAP system copy.
In addition to HR data, the "Data Sync Manager" from the provider Epi-Use makes it possible to select additional objects from the areas of accounting and logistics.
Tables that should be saved beforehand in the old target system.
The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
