Open File Handles for a process

[Satish Kumar Malisetti]

Hello All,

I have a application called mediation , when i am startin a newprocess it is used to collect file and process then deliver to downstream

when i checked out open file handles are increasing for every process by 2 how can find from the application code where these are opening from

ex:

cor 19891 fwsup01a 79u REG 3,0xa 212 15965318 /fwdev3/data (cbfp0004:/vol/fv_FUSD1_APP04954_cbs_pa_0/qt_FUSD1_APP04954_pa_fwdev3_0)
cor 19891 fwsup01a 80u REG 3,0xa 88 18125768 /fwdev3/data (cbfp0004:/vol/fv_FUSD1_APP04954_cbs_pa_0/qt_FUSD1_APP04954_pa_fwdev3_0)


how find these 2 opened

>how find these 2 opened

You would have to debug your application, setting a breakpoint in open.
These open files could also be inherited from their parent?

These two are opening from the application
after file processed

So you need to dust off your grep and debugger skills. :-)

could lsof work or tusc

lsof lists open files

tusc allows you to see system calls for a process while it runs.
