Migration of SAP DB systems (between different databases)
STAD SAP Workload: Business Transaction Analysis
In this step, a dialogue box prompts you to confirm the commit. If the user does not have permission to execute the transaction SPAM or the current queue has not yet been confirmed, the transaction stops SPAM with a message to that effect. CHECK_REQUIREMENTS In this step, different requirements for inserting are checked. There are the following reason that may cause this step to be cancelled: TP_CANNOT_CONNECT_TO_SYSTEM: tp cannot log in to the system database. QUEUE_NOT_EMPTY: There are incomplete OCS jobs in the tp buffer. You can view these jobs using the following tp command: tp SHOWBUFFER -D SOURCESYSTEMS= TAG=SPAM You cannot resume the processing of the queue until these jobs have been completely processed or deleted from the tp buffer. DISASSEMBLE In this step, files are extracted from the corresponding OCS files and placed in the /usr/sap/trans/data (UNIX) directory.
Understanding the structure and functionality of the system is especially important for IT administration. It's 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.
Configuration
SAP Basis experts ensure optimal integration of the SAP system into a company's individual IT landscape. Depending on the agreement, the team of experts takes care of the administration as well as the hosting and operation of the SAP system.
The security of an SAP system requires protection against unauthorised access, e.g. through the secinfo and reginfo files. A cleanly implemented authorisation concept protects against attacks within the SAP system. However, it is also possible to attack your SAP system via the network. Through the RFC Gateway Server, your system communicates with external servers and programmes. One particularly effective way to protect against this are so-called Access Control Lists (ACL). Find out what this is and how you can use it to better protect your SAP system. The SAP Standard offers different approaches for gate protection. All methods combined can provide even greater safety. For example, it is possible to use Access Control Lists (ACL) to monitor exactly which external programmes and which hosts can communicate with the gateway. Another option is to configure the gateway to support Secure Network Communication (SNC). Finally, there are various security parameters for the gateway. This article focuses on the use of ACL files such as secinfo and reginfo files. What is an ACL? Access control lists are files in which permitted or prohibited communication partners can be recorded. For the gateway to use these ACL files, parameters must be set in the default profile of the SAP system and of course the files must be maintained accordingly. With the help of logs and traces, which can be configured for this purpose, a precise investigation can be made in advance of the activation, which connections currently run via the gateway. This allows them to prevent important applications with which your system communicates from being blocked by the ACL files. The rules in the ACL files are read from top to bottom of the gateway to decide whether to allow a communication request. If none of the rules matches the requesting programme, it will be blocked. Network-based ACL The network-based ACL file contains permitted and prohibited subnets or specific clients.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
Since innovations through IoT (Internet of Things) or big data scenarios not only affect the SAP basis, but also highlight products and services for customers of their own company, the role of the SAP basis in relation to these scenarios and services must be clearly defined.
Basis is a set of programs and tools that interface with databases, operating systems, communication protocols, and business applications (such as FI, CO, MM, etc).
