If the additional memory in the Advanced Storage Area is still not sufficient for the user context, the optional second role area can be used. The size of the second roll range is determined by the difference between the parameters ztta/roll_first and ztta/roll_area.

SAP System Monitoring
The basis of every SAP system is the SAP NetWeaver Application Server. Everything depends on this "SAP Basis" to keep SAP systems running. In the area of SAP Basis Operations, we handle all technical tasks for our customers that arise during the installation, operation and maintenance of SAP systems. We install, administer, configure, troubleshoot and optimize your SAP system.
Hosting environments and third-party offerings have also contributed to these improvements. Public cloud environments such as Azure and AWS provide a layer of abstraction that eliminates the difficult task of maintaining the hardware that was required with SAP on-premises.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
