Real-time SQL Monitoring

• Shining new light on long-running SQLs

• What? Who? Where? When?• Resource consumption

• Real-time monitoring of active SQL while executing

• On by default with no overhead for:• SQLs longer than 5 secs • Parallel Query/DML/DDL

• View statistics at multiple levels• System wide• Single Session• Single SQL

• Provide insights into the internals of SQL executions

• Ease tuning efforts

Data Masking

What• The act of anonymizing customer,

financial, or company confidential data to create new, legible data which retains the data's properties, such as its width, type, and format.

Why• To protect confidential data in test

environments when the data is used by developers or offshore vendors

• When customer data is shared with 3rd parties without revealing personally identifiable information

Real Application Testing with SQL Performance Analyzer (SPA)

SQL Plan ManagementBusiness Requirement• Unpredictable changes in execution plans can happen

• New Statistics• Changes in the Environment, Software upgrades

• Today you have to ‘freeze’ critical plans or statistics

Solution• Allow SQL plan changes, but only for the better !• Optimizer automatically manages ‘execution plans’

• Only known and verified plans are used• Plan changes are automatically verified

• Only comparable or better plans are used going forward• Using SQL Performance Analyzer (SPA) to pre-seed with good plans for

critical SQLs before making changes

SQL Plan Management is Controlled Plan Evolution
