Verification of source system status and infrastructure - analysis of software versions, database disk layout, system status, etc.
Even if the target system is not used for production in an update scenario based on a system copy, it is of central importance for developers and thus also the software lifecycle of the production system. That's why you should avoid upgrade downtime in both the production source system and the non-production target system. Production system downtime depends primarily on the method you use to create the image of the production data to be used in the target system. This image must be a transferable database image - for example, a database export, a backup copy, or an array-based reconciliation. To eliminate downtime in the production system and minimize the impact on application performance-regardless of the size of the production data reconciliation-you can use, for example, HP StorageWorks System Copy for SAP (HP System Copy), which has a disk array-based replication capability. Downtime in the target system depends on the following factors, among others: The time required to restore production data reconciliation in the target system The amount of pre- and post-processing in the target system With HP System Copy, images of production data can be created in minutes, with each step between shutdown and reboot of the target system occurring automatically. However, after the reboot, the target system is not immediately ready for use, as additional steps must first be performed (see description below).

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.
SAP system startup and shutdown, including virtual hosts
Third-party tools sometimes have a different focus than TDMS. The tools each offer a more or less generally understandable user guidance and are thus "out-of-the-box" products that do not require external consulting on implementation or application.

A note box in which data of all kinds can be quickly filed and retrieved. This is what Scribble Papers promises. At first, the program looks very spartan. But once a small structure is in place, you realise the great flexibility of this little helper.

After shutting down the target system, the technical system copy for upgrade 1 can be created at the infrastructure level. To automate the creation of the technical system copy for upgrade, HP System Copy can be used for the following steps.

A solution such as "Shortcut for SAP Systems" offers an automatable solution for many of the activities involved in an SAP system copy.

Since there are no options within the client to select what all should be copied, the runtime is often unacceptable.

SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page:

The default is DDLORA.TPL.
