Hi jim,
our DBA has logged call with Oracle and also shared the patches we applied last month to get a response from them. Lets wait and see what oracle has to say on this.
After checking logs, DBA could only confirm that there is very high Logical I/O activity. There is no wait I/O on the system and DBA also confirmed physical I/O is negligible from his logs.
Could it be that the high logical I/O is caused by some application defect ? Also we have lot of memory available on the system which is not used by oracle. Shall i ask DBA to increase SGA to include the free memory ? Will it help reduce the logical I/O. Any comments will be appreciated.
If you are running a modern version of the Oracle DB then you can use and AWR report to determine if the DB needs more ram allocated.
