Total number of write requests written to both Exadata Smart Flash Cache and disk This statistic is incremented once per mirror write. In effect, this is the amount of disk I/O saved by using Write-Back mode. Total number of write requests that overwrote an existing cacheline in Exadata Smart Flash Cache that had not been written to disk Number of bytes that were not offloaded and sent back to the database for processing
Number of bytes that were not offloaded and sent back to the database for processing due to a quarantine on the cellĬell num bytes in passthru during predicate offload Total size of uncompressed data that is processed on the cellįor operations on segments compressed using Exadata Hybrid Columnar Compression, this statistic is the size of the data after decompression.Ĭell num bytes in passthru due to quarantine Number of read requests for temp IO that were satisfied by the cache Number of read requests for smart IO that were satisfied by the cache Number of read requests that were satisfied by the cache Number of calls to routine kcsgrs to get a recent SCN Number of calls to routine kcmgcs to get a current SCN Number of calls to routine kcmgas to get a new SCN The SCN is allocated at the start of a transaction. Number of times a snapshot system change number (SCN) was allocated. Useful only for internal debugging purposes Total number of bytes sent over a database link Total number of bytes sent to the client from the foreground processes Total number of bytes received from a database link over Oracle Net Services Total number of bytes received from the client over Oracle Net Services Useful only for internal debugging purposes. Number of times a buffer was pinned when visited.

Number of times a buffer was free when visited. Number of times an index branch block was split because of the insertion of an additional value This is a count of the times where a background process has set an alarm for itself and the alarm has timed out rather than the background process being posted by another process to do some work.

Individual file checkpoints for operations such as offline or begin backupįoreground (user-requested) checkpoints (for example, performed by ALTER SYSTEM CHECKPOINT LOCAL statements)
This statistic includes only checkpoints of the redo thread. This statistic can be larger than "background checkpoints completed" if a new checkpoint overrides an incomplete checkpoint or if a checkpoint is currently under way.
Number of checkpoints started by the background process. This statistic is incremented when the background process successfully advances the thread checkpoint. Number of checkpoints completed by the background process. The total wait time (in centiseconds) for waits that belong to the Application wait class Table E-1 Database Statistics Descriptions Name
