Troubleshooting and fault elimination
Authorization management: preparation and follow-up of audits as well as ongoing or selective support
The default value of the profile parameter is 1, so the weak hashes are generated for each user. Preventing weak password hashes The generation of unsafe hash values can be prevented by setting the login/password_downwards_compatibility profile parameter to 0. Note that a change only takes effect when the instance is restarted!
Parameters in the SAP create a high degree of flexibility. Profiles can be used to configure the system for almost any purpose. But with such a large number of parameters one quickly loses an overview of the influence of each parameter. For storage management alone, there are 20 different parameters that can be changed at different points in the SAP system. This article brings order to the mess and explains the most important parameters. There are three types of memory in the SAP system for a work process: ・ Roll Area - Local Memory Area for a Work Process ・ Extended Memory - Global Memory Area for All Work Processes ・ Private Storage /Dynamic Memory (Private Memory/Heap Memory) - Private Memory Overview of SAP System Memory Regions Parameters for the Rolling Range When a user starts a programme, a role area is created for that programme instance through a workprocess. The user context is stored in this memory area. The size of the roll area for a work process is determined by the ztta/roll_first parameter. If the storage area is not sufficient, a portion of the Advanced Memory will be allocated for the user context, the size of which will be determined by ztta/roll_extension, ztta/roll_extension_dia, and ztta/roll_extension_nondia. The latter two override ztta/roll_extension if used and offer the possibility to set different quotas for dialogue and non-dialogue work processes.
Daily checks and responsiveness
The following list explains the steps in the order they are performed by SPAM: PROLOGUE This step will check if you are eligible to play Support Packages. CHECK_REQUIREMENTS In this step, different requirements for inserting are checked, e.g. the login of the transport control programme tp to your system. DISASSEMBLE In this step, the data files are unpacked from the corresponding EPS packages and placed in the transport directory. ADD_TO_BUFFER In this step, the queue is placed in the transport buffer of your system. TEST_IMPORT This step checks whether there are any objects that are overridden during the commit and are in unreleased tasks. IMPORT_OBJECT_LIST In this step, the object lists for the support packages that are in the queue are fed into the system. OBJECTS_LOCKED_? This step checks to see if there are any objects that are overwritten during the commit and that are in unreleased jobs. SCHEDULE_RDDIMPDP In this step the transport daemon (programme RDDIMPDP) is planned. ADDON_CONFLICTS_? This step checks to see if there are conflicts between objects in the queue and add-ons installed. SPDD_SPAU_CHECK This step will check if a modification match (transactions SPDD/SPAU) is necessary. DDIC_IMPORT In this step, all ABAP Dictionary objects of the queue are imported. AUTO_MOD_SPDD This step checks whether modifications to ABAP Dictionary objects can be adjusted automatically. RUN_SPDD_? This step prompts you to customise your modifications to ABAP Dictionary objects by calling the transaction SPDD. IMPORT_PROPER In this step, all repository objects and table entries are fed. Then actions such as distribution, implementation, activation and generation take place. AUTO_MOD_SPAU This step checks whether modifications can be adjusted automatically. RUN_SPAU_?
Understanding the structure and functioning of the system is particularly important for IT administration. It is not for nothing that "SAP Basis Administrator" is a career field in its own right. Instead of data and application development, the focus here is on providing the software environment on which the company's tools are created. SAP Basis is therefore comparable to the server and platform infrastructure and its administration in companies - as distinct from application and web development.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
The infrastructure-related SAP basis in turn serves as the link between the application-orientated SAP basis and the infrastructure levels.
This means that confusion in user names cannot be completely ruled out.
