Time at which paging was high??

[Former Member]

Hi,

We had high paging on our production system two days back.

we would like to know the time at which paging was high in a day.

No dumps reported about high paging.

Is there any way of finding the same from OS level.

Ours are AIX sytems.

Regards,

Venkat

Hi Venkat,

Use Tcode ST06 and double click in the required SWAP parameters.

Hope this helps.

Hi Pranay,

Thanks for the reply,

In STO6 I am able to see only last 24 hrs of data. But the paging has occurred on 22nd Jan.

Kindly let me know if there is any way of finding the previous paging status from OS level.

Hi,

You can find that using ST02. In the main screen click on any of the swapped fields (2nd cloumn from right) and from the top click on "history icon" ( icon between "Current Parameters" and "Detailed analysis menu" tab ) - it will show you history details.

As you asked earlier how to check paging from AIX level - you can try topas command fromOS level - but this will also give you real time paging information.

If you have proper permission, you can also try svmon or svmon -P <process id>.

Use the following commands to determine if you need to make changes regarding paging space

#iostat

#vmstat

#lsps

Hi Shivaji,

Thanks for you reply,

Even in the I am able to get the average stats of the page buffer of particular day in ST02, but how to get the detailed stats(hourly) of the that past day so that I can take that time as high paging time and analyze more.

I don't have permission to use the command "svmon *"

Hi Venkat,

Wish you a Happy Republic day.

As per my knowledge we dont have a command to check the swap activity on a particular day.. however you can view the syslog file for any entries...

/var/adm/syslog/syslog.log

#cat /var/adm/syslog/syslog.log

I'm talking about HP UNIX server.
