Key solution steps
TM-TMS (Transport Manager)
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).

After restarting the target system The SAP target instance has been started with a database that has been updated with content copied from the production database using fast and scalable disk array replication. The status of the target system now allows it to run without severe internal errors and disruption to the SAP landscape. However, the system does not have the same identity in the SAP landscape as it had before the update. That's why post-processing is required. UC4 Automated System Copy can handle most of the post-processing by restoring specific database content customizations (such as security settings, RFC targets, and operating modes) that were downloaded before the upgrade. Another goal in post-processing is to change the production system's logical system names to those used by the target system. Since these names usually need to be passed to numerous tables in a given system that have not yet been customized, SAP has the BDLS transaction that can be used to safely analyze and change logical system names. UC4 Automated System Copy can automate and accelerate this transaction by analyzing the underlying processes and executing them in parallel. It can also automate tasks such as reorganizing spools and instructing transport managers to process the delta transport list.

The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
Food for thought for another productive system: until when must the system be identical, keyword: transaction log
Until now, it has been common practice to create test systems as a client or system copy of the production system on a specific date. In these cases, a single client or the entire SAP system is duplicated. The corresponding instances of the SAP system have to be reinstalled. In addition, a copy of the source database must be created. These are standard procedures, but they can be disproportionately expensive for productive data sets of several terabytes. SAP and third-party tools for selective data extraction can significantly reduce the cost of deploying non-production SAP systems.

The suite idea has established itself here as well as in many other software areas. And for good reasons. In addition, such automation tools are moving even more strongly in the direction of the IT topic of system management.

Use "Shortcut for SAP Systems" to make a required SAP system copy easier and faster.

The work that is automated by LSC is in the preparation and post-processing of the files as well as the actual system copy.
