3. Performance Rules overview > ActiveBase Performance includes a powerful rule engine. Each rule is built from a ‘matcher’ (identification criteria) and an ‘action’. Rule matcher identifies a incoming SQL request in real-time based on: SQL syntax, explain plan patterns, Oracle cost, time of day, no. of partition scans etc. > When conditions apply, the rule action will apply on the matched SQL. Actions enable: SQL rewrite, add Oracle ‘Hint’, Block, offload to a replication, delay, ‘search and replace’, rewrite based on PL/SQL function and audit. ActiveBase Ltd. All Rights reserved

15. Rule tree explanation Rules are built as a tree. ActiveBase rule processing engine applies the rules top-to bottom on every incoming SQL request in real-time . When a rule is applied on the SQL, you can specify whether to stop rule processing (and send the SQL to the database for execution), or continue down the tree. A Folder is a means to organize rules according to a common context that is defined in the folder matching criteria In the example, we have on top the tree a folder, with rules controlling user access and full-scans We have high-database load folder for rules applied when database is in high-load ActiveBase Ltd.
