Release upgrades/migrations
In every company with several SAP systems, there is a person responsible for the complete SAP Basis topics, usually there is even a separate department for this. This person ensures the trouble-free operation of the SAP systems. The person responsible also accompanies maintenance work or upgrades and intervenes in special situations, such as poor performance. Even for companies that hand over the operation of the SAP Basis to an external service provider, there are often still tasks from the environment of user and authorization management at this point.
The value for abap/heap_area_total can also be set dynamically in the lower pane. Once you click on the "Apply" button, the values are changed until the next reboot of your system. In addition, the report also provides ways to analyse the global extended global memory hidden behind the two buttons "EG Overview" and "EG Dump".
BACKUP, RESTORE, RECOVERY
It is possible to specify a trace level for each rule in the ACL file to monitor each communication channel individually. It can be used with SNC without any further configuration. The use of the file is controlled by the gw/acl_file parameter by simply setting it to the appropriate file name. Use of external programmes If an external programme wants to communicate with your SAP system, it must first register at the gateway. The programmes which this is approved are controlled by the reginfo ACL file. This defines rules that allow or prohibit certain programmes. The syntax of the file allows you to define not only the name of the programme, but also the host on which the programme runs and hosts that can use and exit the programme. The gw/reg_info parameter must be set to use this file. In addition, there is the ACL file secinfo, which allows to configure which users can start an external programme. This defines rules that allow certain usernames from the SAP system to use certain external programmes. In addition, you can also define the hosts on which these programmes will run. For example, it is possible to allow a user to run the programme "BSP" on the host "XYZ", but not on the host "ABC". This file is controlled by the gw/sec_info parameter. Using the gateway as a proxy Since the gateway of your SAP system can also serve as a proxy server, the prxyinfo ACLDatei should also be activated via the gw/prxy_info parameter. Suppose you have 3 SAP systems in your network: SRC, TRG and PRX. If SRC cannot communicate directly with TRG, but both with PRX it would be possible to use the gateway of the PRX system as a proxy server, i.e. to communicate via it. So, in order to prevent this from happening to everyone, this property should be urgently restricted. As with the other ACL files, rules are defined which hosts can communicate with which hosts via the gateway. The syntax of the different ACL files may vary depending on the release level. It is therefore advisable to read them in the appropriate SAP documentation before activating the ACL files. You can also find more support for using ACL files in the SAP Community Wiki.
The basic operation of SAP Basis includes the operational readiness of the SAP system, management of system changeability, configuration and administration of system profiles, analysis of system failures, operation and monitoring of technical interfaces, scheduling and monitoring of SAP standard jobs, and much more. The optional services as an extension include activities whose execution and frequency depends on the existing system environment and which can be optionally booked (client copies, execution of client transports and homogeneous/heterogeneous system copies, etc.). These include performing release upgrades, installing enhancement packages, adapting new printer types, device drivers or character sets, and much more.
The "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.
Some useful tips about SAP basis can be found on www.sap-corner.de.
Likewise, the SAP base system with the NetWeaver and HANA platform offers an environment in which the SAP programmes can run.
Similarly, this step provides a categorisation of the type of service.
