Operating Systems Solaris Negative impact on Oracle DB after Solaris recommended patching Post 302810529 by abhi_8029 on Wednesday 22nd of May 2013 02:27:41 AM

Hi os2mac,

nothing has changed in kernel parameters in /etc/system

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.
