SAP NetWeaver - maintenance and support
Manage batch jobs
Since 2000 we support companies with individual services around SAP and various databases. Our experts have more than 20 years of experience and support a large number of customers in various industries. You can find examples below.
The database layer is used to store all company data and consists of the database management system (DBMS) and the data itself. In every NetWeaver system there is a database server on which the SAP database is located. It provides all other applications with the necessary data. The data is not only data tables, but also applications, system control tables and user data. All basic components ensure that the user has fast and reliable access to this data.
SM58 Transactional RFC
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.
Depending on whether the user should edit or display the table, either "UPDATE" or "SHOW" can be used here. Enter an X as the value. It is important to use either"'SHOW" or "UPDATE" because a combination will cause an error when calling the parameter transaction. In addition, the table must set the view to be called. Use the "VIEW" field. Finally, the parameter transaction can be created using the "Save" button. As usual, it must be assigned to a package and a workbench order to become available. If a person's role is now assigned permission for this parameter transaction, it can open the specified view above it and does not have the ability to enter all possible views in the SM30.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
When you log in to another client or without the appropriate user profile, you can only use the display functions.
