Application layer (application server and message server)
Each participant will install their own HANA instance for practice ;
SAP HANA base administrators can master the database in a way that wasn't possible back then. The SAP database is much more self-healing. Errors do less damage, are easier to detect and fix, and are less likely to impact system performance and availability before they are fixed. Monitoring tools can automatically scan the application logs, identify potential errors, and even suggest fixes, making it much easier to get to the root of the problem.

You can reduce the Queue selection. To do this, select the Support Package that should be the last in the queue. After that, the queue is recalculated. You can also start the recalculation explicitly with Queue. Note that you can only select Support Packages that are part of the software component you have selected (the mouse cursor will change its appearance accordingly). The support packages associated with the calculated queue are green. The highest support package of the previously selected software component is additionally marked with a green tick. The support packages that are no longer part of the queue are still visible in the list and can be selected again. If you want to set the queue for another software component, select New Component. Result You have defined a queue. Now insert the support packages in the queue [page 20]. Rules for the Queue The following rules apply to creating a Queue: If it is an FCS system, the first step is an FCS Support Package. If it is missing from the queue, it cannot be defined. Instead, you will receive an error message telling you the name of the missing FCS Support Package. You cannot insert an FCS support package in a non-FCS system (official state of delivery). Support packages for a selected component are queued in order. If support packages in the queue have connections to support packages of another component (further predecessor relationship, required CRT), the queue will be extended by additional support packages until all predecessor relationships are fulfilled. Note that the SAP Patch Manager takes into account the configuration of your SAP system and only adds support packages to the queue that can be inserted into your system.

How CodeProfiler for ABAP works
Using profile parameters, we can configure everything in the SAP system. Some parameters are dynamically modifiable, which means that they can be changed without restarting the system. However, these changes are not permanent, i.e. after a system restart, the pre-set profile parameters are used again. Other parameters, however, are static, i.e. only with a restart and only permanently modifiable. Most profile parameters for memory allocation are actually static. However, there is the possibility to adapt it dynamically with the report RSMEMORY. Read how to find out if a parameter is static or dynamic and how to use the RSMEMORY report to dynamically adjust the memory allocation parameters. RZ11 - Maintenance of profile parameters The transaction RZ10 gives us information about profiles, which in turn contain different profile parameters. In the transaction RZ11, however, it is possible to view information about individual parameters, provided that you know their name. As you can read in our Memory Parameter Post, the following 5 parameters are particularly important for memory management: abap/heap_area_total abap/heap_area_dia abap/heap_area_nondia ztta/roll_extension_dia ztta/roll_extension_nondia If you don't know exactly what a parameter might be called, it's worth using the F4 help here. For example, for the parameter abab/heap_area_dia, the RZ11 outputs: Description of the parameter abap/heap_area_dia in the RZ11 As you can see here, it is not a dynamic parameter. Now it is rather sorry if you want to test whether there is enough memory available to restart the system again and again. For this purpose, there is the RSMEMORY report. RSMEMORY - Test your memory allocation strategy Report RSMEMORY Report View No documentation or value help available here, but SAP documentation tells you how to use the report. This first distinguishes between dialogue and non-dialogue work processes. That is, in the first area you can set Extended Memory (Storage Class 1) and Heap Memory (Storage Class 2) for Dialogue Workprocesses, and in the second area you can set it for non-dialogue workprocesses.

Application layer: The application layer is the core of an R/3 SAP Basis system. This layer communicates in both directions, to the presentation layer and to the database layer. The application programs on the application servers request the required data from the database layer, process it, prepare it for the user and pass it on to the presentation layer. Data that the user enters in the SAP GUI is passed on to the database via the application servers.

Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.

Therefore, the customising/workbench developments must be transported to the appropriate system.

So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.


Furthermore, all business and IT departments are aware of the role and the scope of the SAP basis.
