Create SAP HANA system replication levels
SAP system/instance move
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.
Individual steps know exactly where they have to restart the actual copy run in the event of an error. In general, this means that error situations can be handled as needed and with pinpoint accuracy.
This is why companies need professional test data management
Post system copy rework - The collected information from the system copy prework is evaluated and the corresponding transport requests are reimported. The development status before the system copy is thus restored. In addition, this package includes a tool that, when individual transports are released, checks whether there are any overlaps on the target system with transports that are still open there. This prevents a transport from unintentionally "overtaking" an earlier released one with the same objects.
Packages that have not been explicitly assigned a special DDLORA file receive the DDL file specified via the "ddlFile=" parameter. The default is DDLORA.TPL.
Tools such as "Shortcut for SAP Systems" are extremely useful in SAP system copy.
Table splitting requires 2 tools: R3ta, which determines the WHERE conditions used to access subsets of a table.
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.
Increasingly, ad hoc requests are coming from IT or SAP Basis to provide an SAP system copy as quickly as possible, for example of an SAP ERP, BW or HCM system.
