Save time, money and nerves with "Systemcopy as a Service
Planning Guide for the Connector for SAP Landscape Management
System copy of a Unicode system: Source and target system are Unicode systems. The same procedures can be used for the copy, as with the copy of non-Unicode systems.
For some time now, SAP customers have been supported in system copying by very powerful automation tools that can be used as needed. In addition to this area of activity, additional automation tools are also available, for example up to the creation of sandboxes, which provide valuable services.
The system copy
A SAN enables a system copy during dialog operation. In this way, virtual copies of a logical volume, so-called snapshots, can be created. Data is only copied if it is changed in the original data volume (copy-on-write procedure). When copying from a snapshot to file level, the affected systems remain available. However, this procedure puts a strain on the storage network. If this takes several days, the response times of the productive system deteriorate.
Checklist for preliminary work: Comparison of database sizes (target system must be the same or larger), comparison of database versions, kernel, host agent (ideally the same software version), dump of kernel files (export via SAPINST), saves download via SWDC, compile RFC connection passwords, inform third-party system administrators, provide memory, hard disk on the system for database and software import. Perform database dump, if necessary with transaction log, if possible with downtime, then without jobs or stop running jobs with report BTCTRNS1. Adminsitration passwords (DDIC, DB-Admin, Winadmin), create system snapshots (recovery), perform database import.
Tools such as "Shortcut for SAP Systems" supplement missing functions in the area of SAP system copy.
SAP upgrade: Before a very extensive SAP upgrade, you may want to test the run and analyze any errors that occur, especially if the development and test systems are not allowed to be down for too long.
Another goal in post-processing is to change the production system's logical system names to those used by the target system.
