SAP SYSTEM COPY - A BEFORE AND AFTER GUIDE
After restarting the target system The SAP target instance has been started with a database that has been updated with content copied from the production database using fast and scalable disk array replication. The status of the target system now allows it to run without severe internal errors and disruption to the SAP landscape. However, the system does not have the same identity in the SAP landscape as it had before the update. That's why post-processing is required. UC4 Automated System Copy can handle most of the post-processing by restoring specific database content customizations (such as security settings, RFC targets, and operating modes) that were downloaded before the upgrade. Another goal in post-processing is to change the production system's logical system names to those used by the target system. Since these names usually need to be passed to numerous tables in a given system that have not yet been customized, SAP has the BDLS transaction that can be used to safely analyze and change logical system names. UC4 Automated System Copy can automate and accelerate this transaction by analyzing the underlying processes and executing them in parallel. It can also automate tasks such as reorganizing spools and instructing transport managers to process the delta transport list.
The steps to be taken before shutting down the target SAP system can be summarized as follows: Well before performing the upgrade, inform the target system users - especially project managers, developers, and testers - about the planned maintenance work via e-mail, SAP system messages, and/or a message at the system logon. Using the SAP transport system requires careful preparation so that software development projects can be completed as far as possible. Shortly before the start of the update, inform users again that maintenance work on the system is imminent and that they should log off from the target system. After logging users off and locking them out, download system-specific content from the target system database for customization (including security settings, Remote Function Call (RFC) targets, and operating modes).
Critical factor: Availability
In advanced SAP systems, there are also methods such as system cloning, which allows an exact copy of a production system to be created and used as a test system. These methods save time and effort in creating system copies and allow companies to make their IT processes faster and more efficient.
Of course, time savings also mean money savings. In addition, these processes for system copying using such automation tools can be planned, standardized and always run at a high level of process quality. Especially the latter is of great importance in SAP Basis departments (and of course also for service providers).
With "Shortcut for SAP Systems", tasks in the area of SAP system copy are simplified and made possible.
If it is a development system, all newer development objects must be saved and transported back in after the copy.
The website www.sap-corner.de offers many useful information about SAP basis.
As with the latter, the configuration is retained and ongoing development and test processes remain undisturbed.
