Any session that is connected to the database and is waiting for an event that does not belong to the Idle wait class is considered an active session. Oracle Database samples active sessions every second and stores the sampled data in a circular buffer in the shared global area SGA. The sampled session activity is accessible using the VACTIVESESSIONHISTORY view. Oracle Measurement Tool DownloadEach session sample contains a set of rows and the VACTIVESESSIONHISTORY view returns one row for each active session per sample, starting with the latest session sample rows. Because the active session samples are stored in a circular buffer in the SGA, the greater the system activity, the smaller the number of seconds of session activity that can be stored. This means that the duration for which a session sample is displayed in the V view is completely dependent on the level of database activity. List Of Measurement Tools' title='List Of Measurement Tools' />How to calculate IOPS in oracle is a common performance measurement used to benchmark computer storage devices like hard disk drives HDD.

Because the content of the V view can become quite large during heavy system activity, only a portion of the session samples is written to disk. By capturing only active sessions, a manageable set of data can be captured with its size being directly related to the work being performed, rather than the number of sessions allowed on the system. Active Session History ASH enables you to examine and perform detailed analysis on both current data in the VACTIVESESSIONHISTORY view and historical data in the DBAHISTACTIVESESSHISTORY view, often avoiding the need to replay the workload to trace additional performance information. ASH also contains execution plan information for each captured SQL statement. You can use this information to identify which part of SQL execution contributed most to the SQL elapsed time. The data present in ASH can be rolled up in various dimensions that it captures, including SQL identifier of SQL statement. SQL plan identifier and hash value of the SQL plan used to execute the SQL statement. SQL execution plan information. Object number, file number, and block number. Wait event identifier and parameters. Session identifier and session serial number. List Of Oracle Tools' title='List Of Oracle Tools' />Module and action name. Client identifier of the session. 9 Pin Serial Port Usb Adapter. Service hash identifier. Consumer group identifier. You can gather this information over a specified duration into an ASH report. Active session history sampling is also available for Active Data Guard physical standby instances and Oracle Automatic Storage Management Oracle ASM instances.
