Migration to SAP HANA
The area of expertise of an SAP Basis Admin should include:
The core of the three-layer model is the application layer. This consists of one or more application servers and a message server. Companies use the application server to provide services for the operation of applications in SAP. The message server serves as an "intermediary" between the applications and services, for example, by controlling communication between the individual application servers and determining the load on the application servers. Furthermore, the data is prepared for the user in the application view so that the user can call up the data visually in the presentation layer. At the same time, the user data is forwarded to the database.

The SAP Patch Manager offers two scenarios for inserting support packages or queues: Test Scenario Use the test scenario to determine whether conflicts or problems occur (e.g., unreleased repairs) or whether a modification match is necessary before the actual insertion. This scenario allows you to estimate and minimise the time and effort required to load support packages. In this scenario, no data is imported into the system, and you can continue to play in the event of an error without the error being corrected. You must select the test scenario explicitly. Note that once the test scenario has passed, the queue is empty and needs to be redefined. You must also explicitly choose the default scenario.
Further information
You will need to download the support package again. CANNOT_DETERMINE_DATA_FILES: The name of a data file could not be determined because a profile parameter was not configured correctly. Verify the settings using the RSPARAM report. CANNOT_DISASSEMBLE_R_DATA_FILE: Unable to extract an R3trans data file. A possible cause of error is that the appropriate OCS file was not found or the data file could not be opened for writing. An error occurred while transferring a 20K block from the EPS inbox to the /usr/sap/trans/data (UNIX) directory. CANNOT_DISASSEMBLE_D_DATA_FILE: Unable to extract an ADO data file. The reasons are the same as for CANNOT_DISASSEMBLE_R_DATA_FILE. CANNOT_CREATE_COFILE: The cofile could not be created from the corresponding data file. One of the possible causes of error is that adm does not have write permissions for the /usr/sap/trans/cofiles (UNIX) directory.

Some useful tips about SAP basis can be found on

The SAP Patch Manager (SPAM) is the online correction support (OCS) customer site. The SPAM transaction gives you the ability to easily and efficiently import support packages provided by SAP into your system. Depending on the system used or the configuration of your system, you must insert different types of Support Packages [page 8]. You will receive support packages in SAPNet - Web Frontend, in SAPNet - R/3 Frontend or on Collection CDs. Since SPAM runs within the SAP system, you do not need to know the operating system to handle the transaction. In the language usage of SAP, the term patch has been replaced by the term support package. Note that you can only work with this transaction in SAP GUI for Java and SAP GUI for Windows.

With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.

We recommend that you always install the latest version of a SPAM update before installing Support Packages.

This is because the management of the underlying SAP NetWeaver and SAP HANA platforms has become extremely complex.
