Megabits per second measures the file size of data transferred per second over a channel. A megabyte is made up of 1,000,000 bytes. Other names may be trademarks of their respective owners. Megabytes per second generally refers to upload and download speeds. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. The source of the I/O throughput can be investigated by viewingĪ breakdown by either Component or Resource Consumer Group.Ĭopyright © 1996, 2009, Oracle and/or its affiliates. However, if high I/O latencies (for example, Synchronous Single-Block Read Latencies) are causing a performance problem, then reducing the total I/O throughput may help. If a file you download is 100 MB in size, it will take less around 8 seconds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.Ĭonsecutive Number of Occurrences Preceding NotificationĪ high I/O throughput value is not in itself problematic. If your connection speed is 100 Mbps, you can download 12.5 MB of data per second. The following table shows how often the metric's value is collected and compared against the default thresholds. The rest of the information in this section is only valid for this metric when it appears inĮither the Enterprise Manager Grid Control or the Enterprise Manager Database Control (if applicable). A very high value indicates that the database is generating a The total I/O throughput of the database for both reads and writes in megabytes per I/O Megabytes (per second) I/O Megabytes (per second) Description
