Hi DBAs,
I've got one Onesight alert mail stating below:
Short Description: Onesight Alert: ZEUS DB Monitor (zeus04)
Description:
Solaris 5.8: vmstat memory(free) - Free Memory for zeus04 2065112 8:06:02 AM IST 2 min
Free Memory below 4GB: Value was 3,965,488 , threshold is 4194304.0 - 12:36:02 AM IST
Upon issuing OS level commands below I got the following understanding:
prstat
This command returned me the top process ID(3578) which is using more CPU. then,
prstat -Lm -p 3578
this command returned me the following output:
PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX ICX SCL SIG PROCESS/LWPID
3578 oracle 0.7 2.3 1.6 0.0 0.0 90 4.4 1.5 483 235 1K 0 java/838694
3578 oracle 0.3 0.0 0.2 0.0 0.0 95 1.5 0.1 52 8 41 0 java/839336
I thought some Java process would be running so asked the Apps Support team and the said:
we believe this process is related to the Oracle OEM agent Java process
Now how do i drill down the issue and resolve because free memory is going below 2GB almost everyday.
DB environment details:
OS:Solaris 5.8(Unix)
DB version: 10.2.0.5
Memory size:64 GB
Regards,
Ritu
