The Quest for Response Time
Why is Response Time Important?
• Failure to meet service level agreements (SLA)
– Due to long response time
• Customer churns
– Competitive products offer better response time
• Decreased user productivity and decreased customer
satisfaction
– Unhappy customers
• Loss of revenue and decreased profitability
– Effect of lost business and opportunities

In-Memory Database Cache
Flexible Cache Group Configurations
Application
Transactions
Cache Groups
Automatic Data
Synchronization
• Cache Group describes the data in the Oracle
database to cache
• Collection of related tables
– All or subset of rows and columns
– Defined via SQL clause
CREATE CACHE GROUP name
FROM
owner.tab1 (col1, col2),
owner.tab2 (col1, col4)
…
WHERE <predicate>
• Cache tables are regular database tables in
TimesTen
– Joins/search, insert/update/delete
