IO on linux

[satish]

Dear Erman,

Could you please let us know how can we check which process id is causing high IO.we can use iotop which shows process wise IO consumption but this is not installed by default.

Thanks for the support

From OS layer, you can use a tool like "iotop"

it is like "top", but it shows how much I/O each process is doing.

However, you should investigate it from DB level as well... Use AWR and Enterprise Manager.. From Oracle layer, you will identify it.. (if it is an Oracle process)
For other processes on OS, try iotop..
