An instance consists of a SGA and background processes.

SGA (System Global Area) consists of:
* Shared Pool: caching the sql which is shared among users
* Database Buffer Cache: caching the block.
* Redo Log Buffer: buffering the redo log until LGWR generates the redo log
* Large Pool: storing session info, IO slave, RMAN info etc.
* Java Pool
* Streams Pool: used by Oracle Streams

The major background processes are:
* PMON (Process MONitor)
* DBWn (DataBase Writer)
* LGWR (Log Writer)
* CKPT (Check Point)
* ARCn (Archiver)

The statistics in the memory is collected by the MMOM background process per every 60 mins in default, and the collected data is stored in AWR (Auto Workload Repository) in SYAUX for 7 days.

How do I turn on the trace?
The simplest way to turn the trace on programatically is to call

oracle.jdbc.driver.OracleLog.startLogging();

This sends the trace to System.out. To turn it off call

oracle.jdbc.driver.OracleLog.stopLogging();

You can also turn on the trace by setting the system property oracle.jdbc.Trace to "true".

java -Doracle.jdbc.Trace=true MyApp

Setting any of the other JDBC Trace Facility properties described below implicitly sets oracle.jdbc.Trace to "true".
