Shutting Down the Target System
Hybrid: for example, the source systems on-premises and the target systems on cloud
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.
In terms of its architectural approach, BSC takes standards into account wherever possible. As a result, the automation tool can be installed with minimal effort, fits very well into the respective system landscape and offers a fast ROI.
Performing SAP system copies automatically
SAP recommends that you always update enterprise software in your production system using the SAP transport system and never make changes directly in the production system. In addition, SAP suggests that you validate change transports through a QA system that is approximately identical to the production system and has up-to-date transaction data. Outdated data can affect the validity of change transport tests, which can lead to errors and failures in the production system. However, end-user transaction data is received only from the production system. Such data must therefore be passed regularly throughout the SAP transport chain to ensure that your non-production systems have up-to-date and valid transaction data. This can usually be accomplished by passing a system copy of the production system, created for updates, to the QA system. To reduce the number of test cycles, it is also advisable to update your development system occasionally.
Acceleration/table export: up to 4 times faster. The larger the table and the higher the effort for sorting, the greater the time gain during export.
A solution such as "Shortcut for SAP Systems" offers an automatable solution for many of the activities involved in an SAP system copy.
The website www.sap-corner.de offers many useful information about SAP basis.
Because such SAP system copies have to be created for each SAP application on the QA system and can thus quickly require dozens of system copies, they tie up a lot of resources and staff.
The Migration Monitor: is a standalone tool implemented in Java, takes over the management and control of the R3load processes, is downward compatible.
