Re: shared server or dedicated server -- How to find ?

Re: shared server or dedicated server -- How to find ?
Use "lsnrctl services" to see which services have been registered with your listener. Your dispatcher hasn't probably registered it's services with listener. Try "alter system register". If you still don't see any "shared" services (handler=dispatcher) under lsnrctl services, then your dispatchers register with wrong listener (or don't register at all). Check values of local_listener, remote_listener, mts_listener_address and see if they match your listener's address. If the parameters are default then dispatchers try to register them with listener on localhost:1521 If you get your services registered, but all new connections still remain DEDICATED, then check whether you don't have (SERVER=EDICATED) in your tnsnames.ora entries. Note that background processes servers in v$session are always dedicated.

Re: shared server or dedicated server -- How to find ?
Don't worry about dispacther's address, they ought to be running on different ports than listener anyway. Don't use lsnrctl status for checkin services, lsnrctl services is for that. Yes, in Oracle you can directly connect to your dispatcher as well if you want to (some people have resolved firewall port issues that way, by setting dispacther to run on specific port). But generally you should use listener to connect. Listener acts just like a middle-man when estabilishing connection. When a new connection is made to listener and service "orcl" is requested for example, then listener checks whether it has a service "orcl" configured in it's confifguration (listener.ora) or has anyone registered this kind of service with it. If it finds the service, it also knows on which ports are the dispatchers or with which SID should it spawn a new server process.

Re: shared server or dedicated server -- How to find ?
Let me note that I used listener status to figure out services because the output of stat is more compact and easier to read. Of course, one should always use services to look see how services are configured.

Re: shared server or dedicated server -- How to find ?
Prem, MTS configuration requires cooperation of two peaces of software: RDBMS and listener. It's not enough to check the database configuration, you should also check listener.ora and tnsnames.ora On 12/02/2003 03:39:26 AM, Prem Khanna J wrote: Tanel , v$mts, v$dispatcher, v$shared_server all have a record each. but: SQL select server, count(*) from v$session group by server; this query says that all conn are dedicated. but the tnsnames.ora in the client (webserver) doesn't enforce for a dedicated conn. ...and LSNCRSTL STATUS doesn't show anything reg. dispatcher. why it is so ? any thoughts ?!!

Re: shared server or dedicated server -- How to find ?
Your database is not running on either share or dedicated session mode. Your sessions are connecting to either a dedicated server or a shared server. You can have a mix as well. Some sessions may be connecting to dedicated servers while others may be utilizing shared servers. It doesn't sound very logical, but if you want to find out about your sessions, you should go and consult V$SESSION. There is, believe or not, a column called SERVER Here is an example of a query that should tell you everything: SQL select username,server,module from v$session 2 where type='USER'; USERNAME SERVERMODULE - --- OPS$MGOGALA SHAREDSQL*Plus SYSTEM DEDICATED TOra SCOTTSHAREDSQL*Plus SYSTEM DEDICATED TOra SCOTTDEDICATED SQL*Plus So, I have a user called OPS$MGOGALA (I know, I'm a lazy bum, but I hate typing. I really do) logged in using shared server connection from SQL*Plus, user SYSTEM logged in using dedicated server connection using tora (2 connections, schema browser and sessions monitor) , then SCOTT logged in using shared server connection and another SCOTT using a dedicated server connection. Such a mix is typical. For some things I used shared servers, for others I utilize dedicated ones. V$SESSION tells me what is what. Database is said to be in the shared server mode as soon as you have dispatchers and shared servers configured and are able to connect in the shared server mode. Listener should look something like this: SQL $ lsnrctl stat LSNRCTL for Linux: Version 9.2.0.4.0 - Production on 02-DEC-2003 00:19:25 Copyright (c) 1991, 2002, Oracle Corporation.
