Hi Again .    

  When the dbase hangs the listener.log file shows the following errors :    

  TNS-12547: TNS:lost contact
 TNS-12560: TNS:protocol adapter error
  TNS-00517: Lost contact
   32-bit Windows Error: 54: Unknown error     TNS-12500: TNS:listener failed to start a dedicated server process      TNS-12560: TNS:protocol adapter error    

  After i serached about window error 54 i found it is a network error ,also the error may be from swap space and virtual memory ( number of semaphores...) i will increase these and monitor performace event log.    

  Oracle version on window nt 2000 .    

  Can any of you add another suggestions ?

What version of Oracle is this? (and what Win version)? Put the listener in debug mode (lsnrctl then trace debug , or modify the listener.ora )

  I checked the listener.log it shows every thing normal.   however when the problem happens i check tns-service in contral panel->services i find sid service is running however the listner service is not running so i restart the server and so on... is the listener becoming tired when i have many connectins !   the system adminstrator cannot find the meaning of the error " local agent reponse " in the system event , how shall i proceed in the investigation.

what do you mean by 'listener is stopping'? if you do a 'ps -ef|grep tns', you see no tns program running? if that is the case, look at the listener.log (in oh/network/log) to see if there is any error message there.

  I need your help on this urgent issue .    

  Each day iam facing a problem , the applicaton is freezing and all my users (150) can not do any thing and you cannot do any new connections , some times this is accompanied by message (" can ot open dedicated server process...."),   when i checked the services i found that listener is stopped automatically !    

  I wonder why it is stopping IS it that i have to add new listener or what ?   Net work problems ? how i verify that it is a network problem ?   the alert .log do not show anything , the window event shows " local agent error "   where i shall start?    

  Wating your help.
