AIOUG Webinar: Shareable Cursors with Christian Antognini
19 19+00:00 August 19+00:00 2020 @ 14:00 - 15:30
FreeSession Title:
Shareable Cursors
Session Abstract:
The result of a parse operation is a parent cursor and a child cursor stored in the library cache. Obviously, the aim of storing them in a shared memory area is to allow their reutilization and thereby avoid hard parses. But when can they be reused? The aim of this presentation is not only to discuss what parent and child cursors are but also, and foremost, to examine in what situations it is possible to reuse them. In doing so, topics such as bind variable peeking, bind variable graduation, adaptive cursor sharing and statistics feedback will be covered as well.
Christian Antognini is a strong believer that at the core it is all about the data, and on how effectively companies process and take advantage of it. For that reason, since 1995 he has focused on the efficient use of database engines. His main interests include logical and physical database design, query optimizers, and basically everything else related to data processing and application performance management. He is currently working as a senior principal consultant and trainer at Trivadis in Zürich, Switzerland.
If Christian is not helping one of his customers get the most out of databases, he is somewhere lecturing on application performance management or database performance features. In addition to classes and seminars organized by Trivadis, since 2001 he has presented at 100+ conferences and user-group meetings in two dozen countries. He is a proud member of the OakTable Network and is an Oracle ACE Director. Christian is the author of Troubleshooting Oracle Performance (Apress, 2008/2014) and the co-author of Der Oracle DBA (Hanser, 2011/2016).
