«ORACLE ADVANCED COMPRESSION WITH ORACLE DATABASE 12C Introduction The amount of data that enterprises are storing and managing is growing rapidly - ...»

-- [ Page 2 ] --

In this example, we assume that the orders table is defined with Warehouse Compression enabled, so that rows are compressed at that level when they are first inserted. Oracle Database will automatically evaluate the ADO policies to determine when each partition is eligible to be moved to a higher compression level, and when each partition is eligible to be moved to a different tablespace. As with the previous Smart Compression example for OLTP, the automatic capabilities of ADO in Oracle Database 12c make it simple and easy for DBAs to implement ILM for Data Warehousing, and significantly reduce the amount of time and effort DBAs need to spend optimizing storage usage and storage performance.

Conclusion Information Lifecycle Management enables organizations to understand how their data are accessed over time, and manage the data accordingly. However, most ILM solutions for databases lack two key capabilities – automatic classification of data, and automatic data compression and movement across storage tiers.

The Heat Map and Automatic Data Optimization features of Oracle Database 12c support comprehensive and automated ILM solutions that minimize costs while maximizing performance. In combination with the comprehensive compression features in Oracle Database 12c, Oracle Database 12c provides an ideal platform for implementing ILM.
