XI Application threads - why don't they dissapear? for XI basis guys

[MichalKrawczyk]

Hi,

in visual admin - performance monitoring - JARM - thread overview

I see lots of threads for my communications channels

(sender file adapters) but they do not dissapear even if I turn the channel

to inactive - should't they be releasing the thread if the pooling interval

"is not running" and there are no files ?

does anyone know the default behaviour?

thank you,

Regards,

Michal

Hi michal,

I hope you have tried Refresh option to view the latest JARM data.

Also if the several threads have appeared still after deactivation then that may indicate the locking problem.

Thanks

hi Swarup,

Hi Michal,

Under Thread Overview tab you can see the threads running in application. If same action or component get repeated then that will be the case:--> thread was locked. You may need to switch OFF & ON, the JARM Monitoring to resolve it.

Under Performance tracing, the particular thread may have chance to be locked while monitoring, but this completely depends upon the server load. And server load can be indetified as per the listed threads.

Currently the threads that you might be getting will be disappear if either you refresh it or switch OFF the JARM Monitoring and again start it.

I hope explanation may help you.

Thanks

Hi Michal,

just a wild guess.

If they're FTP connections, is the connection with the type "Permanent"?

U may check the following parameter

administration.processHistoryLength Value type: Integer

Default: 25

This property configures the number of process status entries kept in memory for each channel in communication channel monitoring.

The maxConsumer properties define the number of threads to be used to process messages in parallel for each queue type and for each connection definition.

hi,

you can now set it per adapter - not only for all adapters

but this has nothing to do with it I'm affraid
