SAP Performance Optimization
SAP Basis - trends for the coming years
SAP Basis operations manage the IT underlying the SAP system. In addition, the operation ensures the maintenance and availability of business processes. Various tools can be used for this purpose, which take over the maintenance, servicing, configuration and monitoring of the SAP system. Basis operation is the prerequisite for ensuring that the SAP system is fully operational and covers the business processes well.
In order to reduce the complexity of the SAP basis operation and to accelerate and simplify the tasks of the SAPBasis and to create free capacities, standardisation and automation of the existing activities is required. Details can be found in chapters 7.7 and 9.5 of the Master's thesis.

Support Packages from SAPNet - Web Frontend or Collection CDs are available in a compressed format. Note that you must unpack the support packages before processing. Download the support packages from the SAPNet - Web Frontend or mount the appropriate CD. Log in with the following user: Operating system users UNIX adm AS/400 OFR Windows NT adm Go to the following subdirectory in your system: Operating system UNIX and AS/400 usr/sap/trans/tmp Windows NT :\usr\sap\TRANS\TMP Unzip the archive containing the support packages with the following command: Operating system command UNIX CAR -xvf ///_CAR AS/400 CAR '-xvf /QOPT///_CAR' Windows NT CAR -xvf :\\ CHIVE>.CAR Put the unpacked support packages in the EPS inbox of your transport directory: Operating system EPS-Inbox of the transport directory UNIX /usr/sap/trans/EPS/in AS/400 /usr/sap/trans/EPS/in Windows NT :\usr\sap\trans\EPS\in Now bring the support packages into your system with Support Package Upload. You will see a list of uploaded support packages that are now known with all their attributes in the SAP system and can be handled in the right way by the SAP Patch Manager.

SAP will provide all SAP Notes in the SAP ONE Support Launchpad digitally signed. This is to increase the security when the updates are loaded. If you have unsigned SAP hints, there is a risk that the notice has been changed unnoticed and malicious code will be added to your SAP system when you install the notice. This poses a significant threat to the SAP system, which is why the digitally signed provision of the clues is an important improvement. However, to use digitally signed notes in your system, you will need to take a few steps to prepare them. If you install SAPCAR version 7.2 or later and have a user with the necessary permissions, all you have to do is insert the Note 2408073 into your system and do the manual pre- and post-processing. A digital signature technically ensures that any change can be detected at the notice and can be checked by the system to see if the present note, which is to be inserted into the system, is unchanged. Prerequisites to use digitally signed SAP hints To prepare your SAP system for digitally signed clues, you first have to meet some requirements: Digital signed SAP hints are provided as SAR files. The SAR files are unpacked with SAPCAR and checked for their digital signature. SAPCAR must be available on the Application Server in version 7.20 or higher. Therefore, it is strongly advised to update SAPCAR. If SAPCAR is not at least in version 7.20, the digital signature verification fails and the message cannot be unzipped. Installation of the digitally signed clue is then not possible. The implementing user also needs some permissions to perform the necessary manual pre- and post-processing of the note on the system: Authentication for the transaction SLG1 Read permission for the S_APPL_LOG permission to write and delete data from the application directory Upgrade the SAPCAR version on your system to version 7.20 or higher SAP basis version 700 or higher, for older versions the notice must be inserted manually If you have met these requirements, you can use the implementation of note 24080 Start 73. Implementation SAP Note number 2408073.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
