Nearline Database in System Copy

External data access: Setting up a read connection to the nearline database of the productive system. Only read access of the nearline database of the productive system P74 is supported from the Q74 system.

A copy of the nearline database of P74 is connected to the Q74 system. In this way, it is possible to support read and write access.

Companies that implement SAP, perform maintenance, and further development need at least one further system in addition to their productive system in order to perform, for example, development and tests based on scenarios and data that are realistic and current. For this reason, complete productive systems or clients are usually copied. While they copy systems using standard SAP tools, when a nearline database is being used, the question arises how this should be done in the case of a system copy or also of migration. Depending on the requirement, PBS supports two different scenarios:

External system access

If it is only necessary to support read access to the data of the productive nearline database in the newly created copy of the SAP system, then it is sufficient to set up a read connection to the nearline database of the productive system. This has the advantage that no effort is involved for the creation and maintenance of a further nearline database and all nearline data is also available in the copied SAP system for requests and evaluations. At the same time, the data remains protected and cannot be changed.

Copy of nearline database

If it is necessary to support both read and write access to the data of the nearline database with the copy of the SAP system, it is recommended to perform a backup of the productive nearline database with a subsequent restore on the new server. Afterwards, the new nearline database is adapted using special, predefined PBS scripts. The copy including nearline database can be run afterwards as a new production, quality assurance, or test system in parallel to the original system. This is not least of advantage in the case of a migration to SAP HANA.
