![]() While planning a system copy make sure that it is not being heavily used to it is not the end of year closing. This controls the creation of a number of packages. In SWPM, there is a screen where you are asked to provide a Number of Parallel Jobs. Parallel Processing During Export and Import On the other hand, the Backup/Restore method will not change the structure of the database but just make it apple to apple. SWPM will automatically compress the tables during the import phase. This is a more complex process than backup and restore.Īlthough databases dependent copy is the fastest there is a significant advantage of using export/import where you want to reformat the structure of your database across a larger number of files, redistributing the tables and indexes across these files, thus optimizing the I/O load. This method involves the downtime where we have to shut down the SAP system. If SAP HANA is the source database, you cannot use the Database Independent System Copy procedure for SAP systems based on SAP NetWeaver AS for ABAP 7.52, because SAP NetWeaver AS for ABAP 7.52 already uses certain artefacts in the SAP HANA 2.0 database which are not supported by R3load. ![]() It exports the database in a flat file format which is imported on the target system. Software provisioning is the primary system copy tool (there are also other tools such as R3load, Jload, etc.,) used to copy the system from one to other. if the source database is in five physical disks and the target database is on six physical disks.Ģ.Copying using Database Independent Tools -Export/Import using R3load/Migration The only drawback is the physical layout of the source and target physical disks must match as some DBs can’t understand is there is a difference. This is also great for cloning the system to dev or test. After you restore or copy the backup to the target system run the SWPM tool to finalize the SAP DB upgrade as this tool will make some sap specific changes. ![]() ![]() This method involves no downtime to the productions, as DB can be restored for the backup, and hence is a preferred method. We can perform a homogeneous system copy for an SAP system on Azure or On-Prem by below-listed methods.ġ.Copying using Database Specific Tools (i.e. Please, note in the above case the in-place upgrade is not supported but still it will be a homogenous system copy.Ģ.Upgrading your database platform, for example from SQL Server 2008 to SQL Server 2012, you are not changing your database platform, and again it is a homogeneous system copy. Homogeneous System copy does not require special certification and can be performed by an experienced SAP Consultants.ġ.Moving or Copying between same Operating System, for example from Windows Server 2003 to Windows Server 2012 R2, we are not changing the OS and therefore we will call it a homogenous system copy. The purpose of a homogeneous system copy is to stand-up test, demo or training system or to move a system to new hardware. It can be used for Changing the operating system, the database, or both. The described concept has proven its maturity over several years of productive operations for customers of different sizes and branches.SAP Homogeneous system copy is a system copy between the same platforms (i.e. as provided by SUSE Linux Enterprise Server for SAP Applications. An optimal effect of the enqueue replication mechanism can be achieved when combining the application level redundancy with a high availability cluster solution e.g. The SAP Enqueue Replication Server constitutes application level redundancy for one of the most crucial components of the SAP NetWeaver stack, the enqueue service. SAP NetWeaver is a common stack of middleware functionality used to support the SAP business applications. Together with a redundant layout of the technical infrastructure, single points of failure can be eliminated. SUSE Linux Enterprise Server for SAP Applications is the optimal platform to run SAP applications with high availability. Many critical business environments require the highest possible SAP application availability. SAP Business Suite is a sophisticated application platform for large enterprises and mid-size companies.
