It’s not about keeping our kids safe at school. That wasn’t even mentioned in the president’s speech. They only care about their decades-old gun control agenda — ban every gun they can, tax every gun sold and register every gun owner. This president has taken the art of public deception and manipulation to a whole new level. Consider his proposal for so-called “universal background checks.” At first glance, it sounds like a reasonable, good idea. But there’s nothing “universal” about it. Think about it. Criminals won’t be part of their universe. They’ll steal their guns. | VMware vCenter Server Database Performance Improvements and Best Practices for Large-Scale Environments Performance Study TECHNICAL WHITE PAPER vmware VMware vCenter Server Database Performance Improvements and Best Practices for Large-Scale Environments Table of Contents Executive Overview of Statistics Subsystem in Database Performance Removed Staging Partitioned Statistics Redesigned Stored Database Best Practices for Large-Scale How to Lay Out Disks for Both Oracle and SQL How to Update Index Statistics for Highly Volatile How to Separate Tables and Indexes for Improved How to Take Advantage of Features in Enterprise Editions of SQL Appendix Test Bed TECHNICAL WHITE PAPER 2 VMware vCenter Server Database Performance Improvements and Best Practices for Large-Scale Environments Executive Summary VMware vCenter Server introduces some significant improvements to the statistics subsystem. Statistics data represents the largest storage impact in a vCenter Server database and therefore vCenter Server must handle this data in an effective way so that it does not hamper VMware vSphere performance. To help meet this need vCenter Server reduces the resource overhead of the database through enhancements in stored procedures in the database specifically the rollup and TopN procedures. This paper describes these changes and provides the following best practices for configuring the database to best take advantage of the improvements How to lay out disks for both Oracle and SQL Server How to update index statistics for highly volatile tables How to separate tables and indexes for improved performance How to take advantage of features in enterprise editions of SQL Server How to tune certain parameters for Oracle and SQL Server for example the parallelism threshold for SQL .
