Is dedicated server process part of Instance or not?
Hi friends,
I am new to Oracle Database. I have been reading famous book "Expert Oracle Database Architecture" by Thomas kyte. At page no. 62 he has said that "This dedicated server process is not (by definition) part of the instance."
But in the [email protected] documentations at almost most of the places they have mentioned that dedicated server is part of an instance. Interestingly Tom Kyte has coauthored book. I got confused because Dedicated server process would also have PGA so it will be part of Memory so it should be part of instance. So has Tom Kyte said for that particular dedicated process and why? He must have said that with some reason? What is that?
I have also asked my trainer. But I didn't get satisfactory answer.
Thanks.

Can you cite a specific instance of the documentation stating that dedicated server is part of the instance? Your embedded link is a 'mailto' link, not a url to a document.
I can offer specific links stating otherwise.
If I start at Oracle Database Online Documentation 11g Release 2 (11.2) I am at the portal for all database 11.2 documentation.
From there, do a search for 'dedicated server' and get the results of that search at Oracle Database Search Results: dedicated server
The first result returned is the definition, at Glossary
The definition states:
dedicated server
A database configuration in which a server process handles requests for a single client process.
If I follow the embedded link for 'server process', I get the definition of a "server process" at Glossary
Note that this definition is for all "server processes", not just dedicated server. It says
server process
An Oracle process that communicates with a client process and Oracle Database to fulfill user requests. The server processes are associated with a database instance, but are not part of the instance.

ORA-12500 TNSLISTENER failed to start a dedicated server process
Environment W2000 Pro SP4 latest fixes
I just installed database 10g (10.1.0) in order to have a 10g (10.1) database (ORCL1) as required by Oracle Warehouse builder and other business intelligrence products like disoverer (from discoverer suite) and Portal 10g (9.0.4)
during installation of 10g database I got following messages
==>Oracle Cluster Registry failed to initialize (in french) and went on
==>error when starting OracleCsservice
i retried and went on.
Install finishes correctly
I can access the new database (type warehouse) with sqlplus in a dos window
However I can't reach it through SQL*Plus of oracle 10g database and get ORA-12500 TNSLISTENER failed to start a dedicated server process message

I only have one LISTENER service (the one that was created for INFRAstructure instance) is it OK ?
All other databases instances I am using where created from INFRA DBCA. and all defined with a dedicated server.
I tried to define it through DBCA of Oracle database
left dedicated server and finish
won't work DBCA refuses
I also tried to Stop/start OracleServiceOrcl1 but it won't stop
database ORCL1 is unreachable from other instances:
from Oracle WareHouse Builder's Enterprise Manager console I get the same ORA-12500 message
same with Oracle Net Configuration Assistant of
Oracle Developer Suite Net assistant
What's wrong,
is one listener enough? is there a bug in the product?..
I read quite a few enties but didnt get the answer to my problemHello Werner,
What means error 1058?
i posted an entry in application server
Listener.ora and tsnames .ora where updated on INFRAstructure instance to be nearly identical to 10g DB instance (diference is one db definition)
However starting infrastructure and portal instances has become erratic and error prone:u
It takes about 20 minutes to start these two instances by hand has before i had only to start them and everything went smoothly (but took also a long time).
Now i get the following messages and have to use following opmnctl commands to have the whole thing running as follows:
==> start INFRASTRUCTURE
lancement de tnslsnr: veuillez patientez...
failed to start service, error 1058 ==> new message

1)How can we limit the max number of dedicted server processes in a adatabase? or it will be a memory dependent?or any parameter to limit the dedicated server processes?
2)when i connect through database:
a) sqlplus "/as sysdba" or
b)sqlplus
connect sys/password
in the above two a and b cases, the user connects to the database through dedicted server process...right? so i want to over write this default connection means in above two cases i need to connect to the database through shared server process. how its possible...can any one explain?
3)In dedicated connection the resources are fully utilized and in shared server connection the resources are splitted to various users because shared server connection supports multiple user environment. How the resources fully utilzed in dedicated connection and splitted to various users in shared server connection?
Can any one explain this?1)How can we limit the max number of dedicted server processes in a adatabase? or it will be a memory dependent?or any parameter to limit the dedicated server processes?You cannot limit the number of dedicated connections. There is no such parameter. The only restriction that you can impose here is via the PROCESSES parameter.
Doing so, will restrict the number of connections to a particular database (irrespective of dedicated or shared server connection).
in the above two a and b cases, the user connects to the database through dedicted server process...right? so i want to over write this default connection means in above two cases i need to connect to the database through shared server process. how its possible...can any one explain?That's right and I don't think you can override this behaviour. You can get a shared server connection by using TNS alias when your database is running in shared server mode.
3)In dedicated connection the resources are fully utilized and in shared server connection the resources are splitted to various users because shared server connection supports multiple user environment. How the resources fully utilzed in dedicated connection and splitted to various users in shared server connection?Well you need to understand the configuration difference in first place.
Whenever a client connects to an Oracle database (via SQL * Plus, any application etc.), the client connection asks the database server to create a process on the server which will service the client's requests. Then this newly spawned server process would take all the requests from the client and process them and send the results of the same back to the client. This is “dedicated” server configuration.
Each of these client connections takes up some resources (memory, CPU time, net-work bandwidth…) on the database server. More the number of client connections, more is the resource consumption, more is the delay is processing the requests.
The clients can be working continuously or working at intervals. If the clients are working at intervals (e.g. inserting a record in approximately 10-12 minutes), then the “dedicated” server process spawned by this client connection is idle for more than 95% of the time and still consuming valuable resources on the database server.
A database serving an application, where-in most of the server processes spawned by the client requests are idle for 90+% of the connect time, is a good candidate for Oracle Shared server mode configuration.
Shared server is configuration method in which one server process can handle more than one client connections/processes/requests. As there are a few number of server processes created on server, the server resources are utilised to a minimum. This en-ables the database administrator to define more number of dispatcher processes to handle the requests from the clients and more number of shared server processes that handle and process the requests between these dispatchers and database kernel.
Edit: "Hub" beat me while I was typing the whole story :-(

Dedicated Server Process or Shared Server Process
Hi,
I am little confused to justify the number of users that may be best to use dedicated server process or shared server process.
Kindly advice.In addition, make sure you account for administrative issues. It's a lot more challenging to trace applications using shared server connections. Shared server configurations also tend to introduce a variety of gotchas into a DBA's world-- at a minimum, most articles you find on the internet tend to ignore any shared server specific issues. That's one of the reasons that I tend to be of the opinion that if you have to ask, you probably don't need to enable shared server.

Failed To Start A Dedicated Server Process
Hi
Oracle 9.2
Windows Advanced OS
6G Ram
We switched our server from Shared Server to Dedicated. All was going well, but suddenly no one could log in. Currently logged in users were okay.
Alert Log showed several of the following errors:
skgpspawn failed:category = 27143, depinfo = 9261, op = spdcr, loc = skgpspawn
No errors in the listener.log
Attempted login with sqlplus reported ORA-12500: TNS:listener failed to start a dedicated server process
At the time less than 2G of the 6G was being utilized.
Also, during the time of this event, the event log showed several of the following:
Event Type: Error
Event Source: Oracle.ACP
Event Category: None
Event ID: 31
Date: 5/16/2008
Time: 9:48:59 AM
User: N/A
Computer: ACP
Description:
Unable to begin another thread.
Any help would be appreciated.
kdHi Don
Thanks for the info. I now have the 3GB switch set. I have been leery of setting the indirect buffers due to some posts I have read like these:
ORA-00385: cannot enable Very Large Memory with new buffer cache parameters
Cause: User specified one or more of { db_cache_size , db_recycle_cache_size, db_keep_cache_size, db_nk_cache_size (where n is one of 2,4,8,16,32) } AND use_indirect_data_buffers is set to TRUE. This is illegal.
Action: Very Large Memory can only be enabled with the old (pre-Oracle_8.2) parameters.
ORA-07305: ksmcsg: illegal database buffer size.
Cause: The database buffer size must be a multiple of the extended cache mapping size for indirect data buffers to be used.
Action: Verify that the db_block_size parameter is correct in INIT.ORA, or disable the use_indirect_data_buffers parameter.
I'm assuming these are 10G and above errors, but I just don't know.
Our db cache is already at a fairly large size.(see non standard configs below).
Also, is this an either/or thing. In other words, /3GT OR /PAE and indirect buffers, but not both?
Thanks again.

'ORA-12500: TNS: Listener failed to start a dedicated server process'
Hi,
While connecting from one database to another users are getting the below error when they are giving a select statement,its taking around 30 minutes and showing
'ORA-12500: TNS: Listener failed to start a dedicated server process'...
What could be the issue...
Thanks,
Kr.If database to which they are trying to connect is running, then check listener.log ($ORACLE_HOME/network/log).
Probably there is not enough system resources - check opsystem logs as well (on unix /var/log or /var/adm) on windows look at events.
Look into db alert.log as well. -

DB 9i - TNS-12500: TNS:listener failed to start a dedicated server process
hi all,
I have a problem with the following configuration oracle 9.2.0.1 (32bits) on Win server 2003 - enterprise x64 edition - 10GM of RAM.
I installed DB without problem, run server, started listener - seems all is fine. But when trying a remote connection, "listener failed to start a dedicated server process"
log listener -------

I ask You, because I am not too familiar with Windows environment and very likely I forget/miss something obvious (in this env).
Thanks in advance
MarfyI solved installing upgrade to 9.2.0.8.
Now It's all OK.

Memory of dedicated server process
I have an oracle 10G 10.1.02 running on an AIX 5.3.0.10 System
every dedicated server process needs 80MB of memory.
i have 100 users
if i configure for SGA 1.2 GB and for 400 MB PGA_AGGREGAT_TARGET
Do I need really 100*80MB+1.2GB+0.4GB = 9.6 GB of memory??
How can i decrease the need of memory for the dedicated server process without decreasing the performance?I did a
ps -elf|grep oracleDBINSTANCE on the AIX
this gives
F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD
240001 A oracle 938454 1 0 60 20 6bf0b400 86792 f100090005a200c0 09:05:14 - 0:00 oracleENTIRE (LOCAL=NO)
And the core size is sz = 86792 KB -
Reg : Shared server process or dedicated server process
Hi,
Apologies if i have asked a silly question.How do we know whether our DB is running in dedicated server process or shared server process.Hi,
How do we know whether our DB is running in dedicated server process or shared server process.
I assume that, you are asking about the view of Oracle Processes in different OS Platform.
In a UNIX environment, Oracle processes (also other DB Processes) can be viewed as individual system processes.
On Windows platform Oracle Processes (also other DB Processes) are implemented as threads that run within one common Oracle operating system process, oracle.exe (e.g. in DB2, db2syscs.exe process). These processes are not visible when you list processes at operating system level.

Shared server/dedicated server process doubt?
when oracle database is not configured for shared server is it compulsay to include SERVER=DEDICATED clause in the connect descriptor.?
Thankx.Hi,
is it compulsay to include SERVER=DEDICATED clause in the connect descriptor.?No, the MTS is defined at startup time, via the MTS parms.
Here is a sample of shared server definition in the init.ora file:
# Multi-threaded Server parameters
local_listener="(address_list=
(address=(protocol=tcp)(host=sting.janet.com)(port=1521))
MTS_MAX_DISPATCHERS=5
MTS_MAX_SERVERS=20
MTS_DISPATCHERS="(ADDRESS=
(PROTOCOL=tcp)(HOST=sting.janet.com))(DISPATCHERS=3)
service_names=testb1
http://www.dba-oracle.com/unix_linux/epc_disabled.htm
However, be aware that the MTS is not a panacea, especially at times when you want to invoke a dedicated process for your program. For Pro*C programs and I/O-intensive SQL*Forms applications, or any batch processes that have little idle time, you may derive better performance using a dedicated listener process. For shops that segregate task into online and batch modes, the DBA sometimes create separate listeners—one with the MTS and another for dedicated connections.
Hope this helps. . . .

ERROR:ORA-12500: TNS:listener failed to start a dedicated server process
I'm getting this error when connecting to an 8i database. The setup was like this: I had an Oracle 8i database on this server and i installed Grid Control on this server which also created a listener.
From Metalink, I saw the following note: A version 10 listener is required for an Oracle Database 10g database. Previous versions of the listener are not supported for use with an Oracle Database 10g database. However, it is possible to use a version 10 listener with previous versions of the Oracle database.
So I deleted the 8i listener and set up the 10g listener to service the 8i database as well. However, every time I connect to this 8i database, I see the listener refusing the connection. Anything I can do here?
Thanks.I probably have posted this earlier,
please configure the listener static.
In other words, ensure that 8i registers with 8i listener and 10g registers with 10g listener.
c:\blah\blah\8i\.\lsnrctl start listener8i
c:\blah\blah\10g\.\lsnrctl start listener10g

Crystal Report Server XI recurring report instance is not viewable
I have scheduled a report to be run every morning, and each instance return status is "success". However, I encountered the following problem when I try to view instances of the report: There is a long time period of waiting (seems to be waiting for some kind of timeout), and then eventually the message: "A request was cancelled. The necessary security privileges could not be verified. This indicates a problem with the security server."
I also noticed that in event viewer (windows server 2003) I see many failure audits to login to the sql database, and the events contain the login used in my data source.
It's interesting to note, that when I run a single instance of the report "Now" there is no problem.
Some info about the report which may be relevant:
The report uses 2 formula fields to auto-parameterize 2 of the 5 parameters used by a subreport. The other 3 subreport parameters are set when scheduling the report.
The subreport uses a call into a stored procedure in a MS SQL server 2005 database to retrieve its records.
The 2 fields which are parameterized are datetime fields (StartTime, EndTime), and the main report is basically just a wrapper to only show the previous day.
JDBC data source to local Sql server instance.
Also, the crystal report server XI install uses the same sql server instance to store CMS data under a separate database.
I'm stumped on this.
Has anybody encountered this problem?
Is there a simpler way to auto-parameterize the report?
Why are the failure audits occurring when I view the instance of the report? Is this because the instance is setup to use RPT output format?
Are there logs I can look into aside from event viewer? I can't find anything that looks relevant under program files, but perhaps I missed something.
The failure audits would make more sense to me if it occurred with the other report instances, but some instances are shown correctly, and some just do this timeout thing.Hello AV,
please look for the log files here:
drive:install folder\businessobjectsenterprise11\logging
by default c:\program files\business objects\business objects enterprise 11\logging
Please make sure that tracing is switched on for the individual server.
Please find [online docu |http://help.sap.com/businessobject/product_guides/boexir2/en/xir2_crs_install_win_en.pdf]here
