AW: CVS Update - 050627

Ok,

I will do the test tomorrow evening with the old CORBA server. The test with the new POA server comes later.

Regards
Roland

Can you repeat the tests with the latest CVS version? You can choose to use POA server, or the old one.

Regards,
Sasa.

Hi Sasa,

yes it works with SharkInterface but not with ExecutionAdministration.

I had run last night my stress test on a two processor machine with this shark CVS version and it had run very stable. Many thanks.

Regards
Roland

It works find on my side when I use SharkAdmin application. Admin's ProcessInstantiator (which extends WfRequester) calls doneWith() after received event is processed. But the difference is that SharkInterface.doneWith() is used. Can you try to use the same?

Regards,
Sasa.

Hi Sasa,

the call executionAdministration->doneWith( event ) in the method receive_event does not work. There's always a log in the console of the Shark engine:

Warning: object is not removed from collection!

Roland

Hi,

doesn't matter if you use EA or SC, but it is important to call doneWith wit the received CORBA event object.

Regards,
Sasa.

Hi Sasa,

my mistake. I have called doneWith for the wrong object. Sorry for the inconvenience. For which object have I to call doneWith if the method receive_event is called to free up the event? Is it EA or SC?

Regards
Roland

No, 1.1 version can use TrackAndDisconnect set to true, along with the usage of doneWith, and this is proffered way to use Shark CORBA. What could happen, is that you already called diconnect() on EA or SC, and afterwards used doneWith for the object that is already removed from the list of created objects for some connection (i.e. you've created WfProcess using SC, and after calling
disconnect() on SC, you've called doneWith() on EA).

Can you include some logs into methods of CollectiveCORBA (in Collective.java), and SharkCORBAServer.doneWith() method, and see what's going on?

You can use CORBAManualTest to test if everything is working fine (it properly calls disconnect() on SC and EA, and also calls
doneWith() for every created object). I personally used this utility to test CORBA memory leak.


Regards,
Sasa.

Hi Sasa

I'm calling the doneWith methods of the interfaces ExecutionAdministration and SharkConnection.

The object type are:

- activity,
- assignment,
- resource,
- process,
- ActivityIteratorExpressionBuilder.

Could it be that the meaning of TrackAndDisconnect must be toggled?

Greetings
Roland

Can you please tell me for which type of object you are freeing up the memory, and whos doneWith method are you calling?

Regards.
Sasa.

Hi Sasa,

I have a problem with this version of shark. I'm using the method doneWith to free up memory of CORBA objects but in the console log of the Shark engine I see following lines:

Warning: object is not removed from collection!

The config property of shark.conf is as follows:

CORBAServer.TrackAndDisconnect=true


In the task Manager window I can see, that the amount of memory of the process java ( Shark engine ) is increasing. If I toggle CORBAServer.TrackAndDisconnect to false than there aren't any log line like

Warning: object is not removed from collection!

and the memory increase of the Shark engine is much lesser.

Regards
Roland

Hi,

the CVS is updated with some bug fixes:

- DODS stdcaches.jar fixed - it caused concurent exception errors (thanks to Roland Schimmack)
- SecurityManager now reads proper entry from Shark.conf (thanks to Geeta and Sebastian)
- DODS EventAudit and InstancePersistence managers fixed to support persisting of null variables on Oracle (thanks to Roland
Schimmack)
- WfActivityIterator and DODSPersistence manager fixed to properly retrieve activities in a certain state when using
WfProcess.get_activities_in_state() method (thanks to Geeta)
- BaseIteratorWrapper fixed not to throw null pointer exceptions when there is no expression set (thanks to Neville van Deventer)


probably this week, we'll have a bug fix release (mainly because the crucial bug in DODS jar file), so we will appreciate if you can test this version, and give us a feedback if there are some more problems.

Regards,
Sasa.
