Adaptive query throttling To edit authorization objects 1. Click the Edit SAP Authorization Objects link. 2. In the Authorizations pane, locate the object you want, and then click Edit. To delete an authorization object In the Authorizations pane, locate the object you want, and then click Delete. To add a new row for a new authorization object Click Add a new row. Adaptive query throttling The administrator must give permission for this setting to be available to users. The user setting appears in the Advanced Run Options pane. Using a patent-pending algorithm, QUERY adaptively throttles the execution of the query on the SAP server based on the current load on the SAP server. The available server resources are calculated from the total number of open dialog processes. When over 50 percent of the dialog processes on the SAP system are available, the query is executed at full speed, but when the available server load starts falling below 50 percent, the execution of the query is dynamically slowed. Adaptive throttling addresses the performance concern around querying on a live transactional system that query execution could take substantial computing resources that might compete against regular SAP transactions, and adversely affect the performance of these transactions. QUERY addresses this issue by allocating only available compute resources to execute queries in the live SAP system. The graph below shows the query performance time against the system load with and also without the adaptive query throttling algorithm applied. When the throttling algorithm is applied, query execution slows as the system load increases; however, without the algorithm, the query executes in constant time and competes for resources with other transactions on the system. 107
