Re: Re: 回复：_Re:_[OB-Users]_a_question_about_how_to_use_a_common_connection_in Orbacus

Stan Lewis,
   In ooc.conf, if ooc.orb.conc_model is setted to threaded,  ooc.orb.cli=
ent_timeout=3D2 works well.
The following is the result:
----------------------
		******************Before string_to_object()...	=09
		Before narrow()...
		[ outgoing: trying to establish connection
		  timeout: 3000ms
		  id: iiop
		  remote address: 192.1.101.205:32323 ]
		[ outgoing: new connection
		  id: iiop
		  local address: 192.1.101.205:36612
		  remote address: 192.1.101.205:32323 ]
		[ outgoing: closing connection
		  id: iiop
		  local address: 192.1.101.205:36612

		  id: iiop
		  local address: 192.1.101.205:36614
		  remote address: 192.1.101.205:32323 ]
		before  say_hello() 1, sleep 10...
		After  say_hello()...
		[ outgoing: closing connection

		  local address: 192.1.101.205:36614
		  remote address: 192.1.101.205:32323 ]
		[ outgoing: closing connection
		  id: iiop
		  local address: 192.1.101.205:36613
		  remote address: 192.1.101.205:32323 ]
		******************Before string_to_object()...
		Before narrow()...
-----------------
    from the above, we can see the first connection(192.1.101.205:36613 t=
o 192.1.101.205:32323) was closed at the end of run() procedure, but we h=
ope it should be closed before the output "before  say_hello(), sleep 10.=
..", because here it sleeps 5 seconds. why is the second connection(192.1=
.101.205:36614 to 192.1.101.205:32323) not closed before the output "befo=
re  say_hello() 1, sleep 10...", here it also sleeps 5 seconds?  A now co=
nnection should be open for the second say_hello() call.  What is the dif=
fence between threaded and reactive client?
