Oracle TimesTen, In-Memory Database
0 likes1,393 views
Oracle TimesTen is an in-memory database that provides the following key capabilities: 1. It has a basic architecture that includes APIs, a storage manager, and transactional durability. 2. It supports high availability through multi-master replication between an active and standby database. 3. It allows caching of data in an in-memory cache grid that scales out as more grid members are added.

configuration
[Left Graph] the grid scales very effectively as we increase the number of grid members
[Right Graph] the performance of global scans scales fairly linearly with the number of
participating grid members](https://image.slidesharecdn.com/lahiripptxoracletimesten-150322091644-conversion-gate01/85/Oracle-TimesTen-In-Memory-Database-7-320.jpg)

- 4. Conclusions and FutureWork Experimental Results IMDB Cache GridIntroduction Basic Architecture High Availability If a failure of the Active occurs, the Standby can be promoted to become an Active Database. If a failure of the Standby occurs, the Active will then replicate directly to the Read Only Subscribers.

Conclusions and FutureWork Experimental ResultsIntroduction Basic Architecture High Availability IMDB Cache Grid Cache groups is a syntactic declaration and comprises one Root table, and optional Child tables related by foreign key constraints. Root Table Child tables In-memory cache grid, which consists of a collection of IMDB Caches for an application’s cached data and is deployed in the application tier. Cached data is distributed among the grid members.

Conclusions and FutureWork Introduction Basic Architecture High Availability IMDB Cache Grid Experimental Results Response time and throughput : The combination of in-memory execution and direct-linked access allow TimesTen to provide extremely low response times The experiment of response times was run on a standard commodity Intel Xeon 5670- system with 2 processors and 12 cores, running Oracle Enterprise Linux 5.6. The measurement of throughput were taken on a SPARC T5-8 system with 128 cores for TPTBM* and on a SPARC T5-2 system with 32 cores for a mobile call processing benchmark. * TPTBM : The standard TimesTen throughput performance benchmark
