RESOLUTION OF SILO EDUCATION AND/OR SEPARATION OF SAP AND NON-SAP SPLITS
Maintaining the availability of critical business processes not only requires a high-quality infrastructure, but also places equally high demands on the management and operation of the underlying SAP NetWeaver and SAP HANA platforms due to their high complexity. These platforms are often referred to as SAP Basis.
After installing the GUI, the GUI patches should be applied as far as available. This includes the hotfixes after the patches, which are necessarily installed after the patches. BI Addon Patch A new service package and patch may need to be installed. It may also be that can be patched directly if another SP exists. The process takes about 30 minutes. The progress of the installation pauses at a certain percentage, as already mentioned above, so you do not have to cancel the installation prematurely. If the installation is not possible, the latest version will be included in another setup. Installation of the Precalculation Server The Precalculation Server is installed. You can also install any patches here. Service The installations create a service. This can be called under Services. Set the Startup Type of the service to "Automatic" (Standard Manual) Enter Login Credentials Recovery for First and Second Failure to "Restart the Service" Start Service Logon SAP Login to the SAP system with the appropriate client from the Precalculation Server. You can use the SAP system's own login. Warning: There must be permissions for the transaction RSPRECALCADMIN and SM51. The transaction SM51 will then be called. Before creating the instances, it must be ensured that the correct application server is selected, otherwise problems with the instances in the user's application may occur later. The transaction RSPRECALCADMIN is then called. A certain number of instances are displayed. They should all be marked and deleted until the view is empty again. They are then re-created with a continuous numbering in order to distinguish them later. Only the ID and description must be entered. The rest will be awarded automatically. The service will now restart and all instances should be green. This may take 2-3 minutes. Important: In the end, all instances must be green. This completes the creation and configuration.
What is SAP Basis Operation?
New risks in SAP HANA: In addition to the known risks, there are also new risks from the use of SAP HANA. A very good example are frequently used web applications that represent something new in the SAP area. In contrast to an SAP ERP system, HANA systems consist mainly of web applications, which were considered optional in the previous versions. These web applications can be found by various search engines on the Internet. This also applies to SAP Portal or Netweaver. There are URL schemes that help locate the system. This also applies to other SAP systems that use Web applications. This makes the new technology vulnerable to typical web attacks. SQL Injection, ABAP Code Injection, or XSS are all included. All risks known for a normal SAP system also apply to a SAP-HANA system. The data is stored unencrypted in RAM. Only then does the system gain this speed advantage. This results in risks such as a read-out by memory scraping malware. These pick up data in memory. Encryption costs performance, so it is not used by default. Especially during a migration HANA runs in a parallel system, therefore at least one new system comes to your landscape. Also note: HANA has its own tools and settings that need to be known and configured. The bottom line is that the system simply needs more attention when operating. Many settings often result in more errors. Three - points - HANA Security Plan 1) Roles and permissions In a previous SAP system, roles and permissions are certainly one of the main pillars of a secure system. Roles and permissions work differently in a HANA system. There are two types of users: 1) Default (limited): With this type of user, there are different access methods to the database. For example, the JDBC or HTTP technologies are used to give two examples.
SAP Basis is also known as module BC or application Basis. In this context, SAP Basis refers to all transactions, programs and objects that control the functions of the overall system. This includes, among other things, user and authorization management as well as the configuration of interfaces via RFC.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
On this page you can find out what is behind the term and what SAP Basis is responsible for in detail.
With an 'X' in this three-digit switch value you can now explicitly specify at which position in the user name no wide spaces and control characters may occur.
