[omniORB] Re: removing unnecessary entries from the log file ?

[Stefan Radke]

Hello,

thank you for your reply. In fact, I meant that the objects no longer exist.
They remain logged in the log file, and the NamingContext's list() method
seems to return the list from the log file.

Is there any other way to find out, if an application is still registered with
the name service or not, without trying to obtain an object reference ?
How 'expensive' is it, to try, if an non-null object reference is returned by
the name service for resolve(objName) ?
