TROUBLE-SHOOTING
BDLS Conversion of logical system names
In many companies, the SAP system is the linchpin of everyday business. To ensure that the system is available at all times, an SAP Basis team ensures its smooth operation.
The Advanced Memory thus contains mainly user contexts of different work processes, if these cannot be loaded completely into the roll area. Since the storage area is accessible for all work processes, the work processes can also access external user contexts that lie here. In addition, the Advanced Memory contains a global area where data can be stored independently of user contexts. The extended memory size is determined by the values of em/initial_size_MB and em/global_area_MB. The first parameter determines the size of the storage area in which user contexts can be stored, and the second determines the size of the global area. Parameters for Private Storage Last but not least, there is the private storage, which is only used when the user context of a work process has used up all the other storage areas available to it, i.e. its share of the extended memory and its rolling area. In this case, the workprocess goes into PRIV mode. A workprocess in private mode is bound to its current user context and will not become free for other tasks until the current request is completed. If it has used up all the private memory allocated to it, the workprocess will then be restarted and the memory released. This behaviour is controlled with the abap/heaplimit parameter. At times, the user context may exceed the value of abap/heaplimit. The parameters abap/heap_area_total, abap/heap_area_dia and abap/heap_area_nondia define an upper limit for private storage. The abap/heap_area_total parameter defines how much private storage all workprocesses can use in total. The parameters abap/heap_area_dia and abap/heap_area_nondia, on the other hand, determine how much private storage a single (non-)dialogue workprocess can use.

Remove weak password hashes from the system: Only updating the profile parameter does not provide you with the necessary security. There are still many weak hash values in your database that can be used to attack your system. These must be completely removed from the database. To do this, use the report CLEANUP_PASSWORD_HASH_VALUES. To do this, call the transaction SA38 and enter the name of the report in the input field. Run or F8 executes the programme and cleans your database Report CLEANUP_PASSWORD_HASH_VALUES This programme removes the outdated hash values across all clients.
