Reliable and fast rework after SAP® system copies
Hybrid: for example, the source systems on-premises and the target systems on cloud
Over 30 productive systems at more than 9 customers successfully copied using IMIG. For the Unicode conversion of a 4.5 TB system (2.7 TB data) a downtime of 16 hours was achieved (including the follow-up work such as reconfiguration, updating DB statistics, generating reports, creating backups, testing the system).
Security-conscious companies usually keep their mission-critical IT infrastructures redundant anyway. Storage systems are usually secured in disk arrays by multi-level raid, spatially separated from each other and networked by a storage area network (SAN). Connected to this are at least two computers, also spatially separated. One of these acts as a backup system.
Create SAP HANA system replication levels
Database: For some databases (MS SQL Server) there is the possibility to copy the database files and reattach them on the target system. For the following SAP installation you only have to specify that no SAP loads should be used, but that the database is already there!
Unicode conversion: A Unicode target system is built from a non-Unicode source system. Unicode conversion can only be performed using procedures based on R3load.
"Shortcut for SAP Systems" can considerably simplify and shorten a number of activities within the scope of a system copy or a system refresh. By using this application in conjunction with the information on system-specific tables from the PCA tool, the system-specific data can be backed up and restored after the system copy / system refresh. As a result, many of the activities mentioned here regarding data backup / restore can be performed much more easily; the creation of screenshots and the subsequent manual restoration of the state documented in this way can then be completely eliminated.
Because the reliability is limited by the misuse of the backup system and the storage network is additionally burdened, users should keep the runtime of this refresh variant as short as possible.
The website www.sap-corner.de offers many useful information about SAP basis.
So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
There are now a number of tools that simplify refresh activities of non-production SAP systems.
