Migration of SAP systems to HANA DB
The database layer is used to store all company data and consists of the database management system (DBMS) and the data itself. In each NetWeaver system there is a database server on which the SAP database is located. It provides all other applications with the necessary data. The data is not only data tables, but also applications, system control tables and user data. All basic components ensure that the user has fast and reliable access to this data.
Transporting transport orders from one system line to another or importing third-party transport orders into the SAP system is also an occasional task for an SAP basis administrator. As in my last blog post on system modifiability, I would like to offer you a way to quickly present this topic. So you will find a step-by-step guide which you can follow if you have already understood the content of the topic, but only the steps need to be taken. What are the requirements? Transport orders include two files, titled "data" and "cofiles". These files consist of a six-character alphanumeric combination and a file extension, which often represents the system from which the files were exported. The first character is always a K (the cofiles file) or an R (the data file). For our example we call the files K12345_DEV and R12345_DEV. These files are of course needed for an import into your own SAP system. Furthermore, you need access to the file system or the SAP directories, as they have to insert the above files there manually. In addition, the transaction STMS is required in the SAP system because it attaches the transport orders to the import queue. Now, if you have all of this available, we can start with the import: What is the procedure? Operating System Level Preparation. The first step is to copy the files to the transport directory of the SAP system. This is usually below /usr/sap/trans, but can be changed individually depending on the system. If you want to make sure that you are working in the correct directory, you can look in the transaction AL11 to see which directory is specified under "DIR_TRANS". This is the right directory to work on. Here the existing files are copied into it, namely the cofiles file (K12345_DEV) in the cofiles folder (/usr/sap/trans/cofiles) and the data file (R12345_DEV) in the data folder (/usr/sap/trans/data). Note: In this case, especially for companies with multiple systems on multiple servers, the access permissions and the file owner need to be changed so that the import in the target system does not cause problems.
Client Management
The SAP Basis Plug-In is backward compatible and follows the release and maintenance strategy of the SAP R/3 Plug-In. SAP ships it together with the SAP R/3 Plug-In.
Basis is a set of programs and tools that interface with databases, operating systems, communication protocols, and business applications (such as FI, CO, MM, etc). The full form of BASIS is "Business Application Software Integrated Solution".
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
The cause of the error can be found in the appropriate protocol, for example in the import or generation protocol.
An Oracle administration expert with a decade of experience understood perhaps only about 5% of what the database required.
