Process Map for CPU and Memory for OS processes

Posted on 20-Dec-2005 By Admin No Comments on Process Map for CPU and Memory for OS processes

Remember :

2 commands to see OS stats.

(1) TOP : This command will provide following information.

SIZE column display Memory allocated to this process.

RES column display Actually allocated memory for the process.

tuningdb21->AWRTEST@(/db1/home/oracle/paresh)top

load averages: 0.17, 0.15, 0.14 10:51:36

120 processes: 119 sleeping, 1 on cpu

CPU states: % idle, % user, % kernel, % iowait, % swap

Memory: 10G real, 6893M free, 2062M swap in use, 8201M swap free

(2) PMAP -X 14627 : this command gives process wise memory usage.

This command will display All details about particular process Map.

Column KBytes displays total memory allocated by all inidivisual process.

Column Resident displays actual memory used by individual components of process.

Column Shared displays Shared memory usage of individual components of process.

Column Private displays private memory usage of individual components of process.
