Please post me Helpful LinksYOu need to understand that ... as far as the database is concerned ... it's not an either/or situation between dedicated and shared server. Setting shared server parameter like DISPATCHERS simply allows the database to handle shared server connections. But it is up to the client to specify which method it wants, and the database will always allow dedicated server connections.

Problem with shared server mode

Hi,
I want to run my database in shared server mode.I have configured the fallowing parameters in init.ora
SHARED_SERVERS=2
MAX_SHARED_SERVERS=10
DISPATCHERS="(PROTOCOL=TCP)(DISPATCHERS=2)"
Then I opened the database.
In another sql*plus session and logged in as scott.There i ran a script to insert 50,000 record s into a table.When the script was running i opened another session as SYSDBA and queried v$shared_server view.
It showes.

Why it is ahowing status as WAIT and requests 0.
What is wrong with my init.ora setting.Please help me.

Hi,
Shared servers (the MTS) does not use PGA RAM, it gets RAM from the large_pool_size region.
BTW, I don't recomend using shared servers unless you have an acute RAM problem:

Sutdown of a Database in Shared Server Modus

Hi,
I have set up today a database called "db03" in Shared Server Mode. After the installation everything looked fine beside that there was no entry in the listener.ora file for the Database. Anyways I added the entry to the listener.ora and was able to connect to it via the command
sqlplus "sys@db03 as sysdba".
But when I tried to shut it down it gave me the error message
ORA-00106: cannot startup/shutdown database when connected to a dispatcher
back.
So I have checked in several forums and someone said the solution would be to connect to the Database via dedicated connection and there for a entry in the tnsnames.ora file must be added.
(server=dedicated)
I added the line to connection descriptor and if I connect back to the database it really works and I am able to shutdown the database.
But is that really the best and Oracle recommended what to shutdown a Database running in shared server mode ????
Thanks Marcus

There is a note in the administrator's guide that you have to have a dedicated connection to be able to shut down the database...
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96521/start.htm#7871
When a database is running in shared server mode, that just means that connections can be made to a shared server, not that all connections should connect to a shared server. When you are doing certain types of tasks, such as reporting, you are frequently better off requesting a dedicated connection. When you are shutting down the database, you have to request a dedicated session.
If you expect some of the sessions started from a particular machine to need dedicated connections and other sessions to require shared server connections, there are options other than modifying the TNS entry, but 99 times out of 100, anyone who will be shutting down a database will always want a dedicated connection.

Need To Create a table in Sql Server and do some culculation into the table from Oracle and Sql

Hello All,
I'm moving a data from Oracle to Sql Server with ETL (80 tables with data) and i want to track the number of records that i moving on the daily basis , so i need to create a table in SQL Server, wilth 4 columns , Table name, OracleRowsCount, SqlRowCount,
and Diff(OracleRowsCount - SqlRowCount) that will tell me the each table how many rows i have in Oracle, how many rows i have in SQL after ETL load, and different between them, something like that:
Table Name OracleRowsCount   SqlRowCount  Diff
Customer                150                 150
0
Sales                      2000                1998
2
Devisions                 5                       5
0
(I can add alot of SQL Tasks and variables per each table but it not seems logicly to do that, i tryid to find a way to deal with that in vb but i didn't find)
What the simplest way to do it ?
Thank you
Best Regards
Daniel

Hi Daniel,
According to your description, what you want is an indicator to show whether all the rows are inserted to the destination table. To achieve your goal, you can add a Row Count Transformation following the OLE DB Destination, and redirect bad rows to the Row
Count Transformation. This way, we can get the count of the bad rows without redirecting these rows. Since the row count value is stored in a variable, we can create another string type variable to retrieve the row count value from the variable used by the
Row Count Transformation, and then use a Send Mail Task to send the row count value in an email message body. You can also insert the row count value to the SQL Server table through Execute SQL Task. Then, you can check whether bad rows were generated in the
package by querying this table.

EJB newbie -- do i need to create the database?

I know this may seem an odd question but do i need to create a database and create all the tables with commands such as: CREATE TABLE (...)? or will the deployment descriptor do that for me?
clarkie

if u are using entity beans there is no need to create database.
u can make use of create function of the entity beans...if u are using bmp u need to write explicitly the code(sql code) for creating the database
if u r using cmp u dont need to explicitly write the code for creating the table

How to find documents on Configuring database to work on Shared server mode?

Hi,
Where can I find documents to configure my database (Oracle 9i Release 2) to work on Shared server mode?
The Aix 4.3.3 platform has 1 CPU and 1G Memory,and can support only less than 20 connectiions while serving a B/S application.So I want to try MTS.

Hi,
a good help for me was this

Not able to get Shared Server Mode to work in XE

The server is an HP Dual CPU Xeon, 4 GB RAM. 120GB HD.
Oracle XE reports the following:
SGA 768 Target, 768MB Current.
PGA 256MB Target, 55MB current (when there are a small number of client connections)
The application and database work properly with a small number of connections, but
memory usage goes way up on PGA when I start to add more connections.
I have tried to set up the Oracle server in "Shared Server Mode" , but it appears
that I was unsuccessful.
From what I can tell, the oracle listener does not seem to be fowarding the incoming requests to the shared server dispatchers, but
instead it is deciding to kick off a dedicated server process to handle each client request.
In other words, it is working in dedicated server mode.
I am stumped as to what needs to be done next. From what
I can tell from reading documentation this should be working.
Please advice as to what else I can do to get things working.
Here is additional information:
The parameter SHARED_SERVERS is equal to 4.
parameter dispatchers=(PROTOCOL=TCP) (SERVICE=XEXDB)
max_shared_servers, max_dispatchers, shared_server_sessions have no values.

I don't think it is supported because of XE multiple cpu usage limitations but "shared server" is not documented in the XE documentation - http://www.oracle.com/pls/xe102/ranked?word=%22shared+server%22

How to convert dedicated server-mode to shared server-mode ?

Hi
I am having 3 oracle client machines(each with sql*plus or Toad tool),all these 3 client are to be connected through Jboss-4.0.5(application server) to Oracle 10g database server.
[ all 3 clients + 1 application server + 1 database server are with different ip address]
Question-1
Is it possible to convert a running Oracle-10.1.0.2.0 database server in[b] Windows server-2003 os from dedicated server-mode to shared server-mode ?
Question-2
What all are the init parameters I have to change ?
So far I have changed (a) alter system set shared_servers=5;
(b) alter system set dispatchers=(pro=tcp)(dis=3);
(c) alter system set max_dispatchers=10;
(d) alter system set shared_server_sessions=5;
(e) alter system set circuits=300;
Question-3
How to configure Listener in the Client system ?
Question-4
What all are the changes to be made in Jboss server ?
Regards
Sbmk_design

ad 1) Yes this is possible
Ad 2) From the top of my head, these seem like the settings to change
Ad 3) You do not have to change the listener (ow.. and clients have no listener) just make sure that you do not have '"server=dedicated" in your local tnsnames.ora file
Ad 4) in jboss, just check your datasource. If it is using a thin connection you are ok, if you are using a oci connection check the tnsnames.ora file.

Oracle 10gr2 rac, ora-12545 error when configured in shared server mode

Hi i have fresh installation on two node rac on linux, with oracle 10gr2. It is running successfully, when i configure it in shared server mode and try to connect from client it gives error ora_12545:
I have referred the oracle metalink notes and configured the local_listener as well as the remote_listener,
still it is giving the error. I am able to tnsping all the entries on tnsnames.ora,
i m also able to ping the hostnames,
It connects most of the times succeessfully but some times it gives the error.
how to solve this problem,
please help me

Basically this error means you misspelled the hostname or typed a wrong IP Address.
Oracle Error :: TNS-12545+
Connect failed because target host or object does not exist
Cause
The address specified is not valid, or the program being connected to does not exist.
Action
Ensure the ADDRESS parameters have been entered correctly; the most likely incorrect parameter is the node name. Ensure that the executable for the server exists (perhaps "oracle" is missing.) If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric IP address and try again.
I suggest you to check the dispatcher instance parameter.
