Solution Description
SAP Landscape Copies
Heterogeneous system copy: As the name suggests, the operating system and/or database on the source and target systems are different. One takes thus in the context of the copy a platform change. This procedure is currently gaining in relevance, as it is required for the migration from SAP ERP to S/4HANA. If the current system runs on Windows Server and SQL Server or Oracle, the target system must now run on Linux and SAP Hana.
On the other hand, such a tool must ensure that traceability or transparency is always available. What happens in the smallest detail during an SAP system copy creation must be visible in whatever form in order to be able to track down possible errors, but also, for example, to optimize the actual copying process or to accelerate it even further, for example by using log files and more.
Several advantages at once
When executing a system copy, all tables, processes, databases, etc. are taken into account when copying. Logical system names must also be converted (using the BDLS trasaction code). The process of a system copy usually does not change. If no structural changes have been made to the SAP systems involved, the process is even 100% identical. Due to the very high repeatability of the nevertheless complex process, it is advisable to automate it to a large extent.
Third-party tools sometimes have a different focus than TDMS. The tools each offer a more or less generally understandable user guidance and are thus "out-of-the-box" products that do not require external consulting on implementation or application.
Tools such as "Shortcut for SAP Systems" are extremely useful in SAP system copy.
In addition, daily work can continue as normal.
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system. Here you can find some useful information about SAP Basis: www.sap-corner.de.
So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.
For the following SAP installation you only have to specify that no SAP loads should be used, but that the database is already there!
