Newbie ORA-12500 Connection Error

I am attempting to connect to the Oracle 10g database with JDeveloper, and whenever I attempt to connect, I receive this message:
Listener refused the connection with the following error:
ORA-12500, TNS:listener failed to start a dedicated server process
The Connection descriptor used by the client was:
192.168.0.101:1521:ORCL
I have tried using the computer name, localhost, 127.0.0.1, I get either an error saying that the network adapter can not resolve the connection, or the error message above. When connecting, I use Net Manager to configure the addresses. Any help would be greatly appreciated since I am a complete newbie to Oracle tecnologies.
Thank you in advance
Ryan

I am logged into SQLPLUS with no problem as the SYSTEM account, (I only receive the problem when trying to log in through JDeveloper) and I altered the spfile processes to 200, however...
bounce the database.I do not know how to do this, what command do you use to bounce the database and what does it do, also...
Then just restart the Listener from the command prompt
lsnrctl stop
lsnrctl startWhen I attempt to do any lsnrctl functions, including help, I receive this error in SQLPLUS: SP2-0734: "unknown command beginning "lsnrctrl s..." - rest of line ignored."
Any suggestions?
Check if the problem is solved.The problem is still the same after altering the spfile, hopefully after I bounce the database and reset the Listener, this will be fixed.
Thank you for all your help so far

ORA-12154 Connection error from HFM to Oracle Database

Hi,
I am trying to configure Hyperion HFM but can write to HFM database.
The implementation architecture:

All the products from server 1 are working fine, FDQM (server 2) is also working fine, but, when I try to do any action related with HFM database the system fails.
I have tested the connection is these scenarios:
1. SQLdeveloper: successfull!, I can create tables, views, etc. Double checking the user privileges it has all the required.
2. tnsping: successfull!
3. HFMApplicationCopy utility: Successfull using UDL file and writing the connection parameters.

Hi,
I Have solved one of my problems, the one that keep HFM from connecting to the Oracle database.
I just change the TNSNAMES.ORA, like this:
Initial tnsnames.ora
PRUEBA.WORLD=
+(DESCRIPTION_LIST =+
+(DESCRIPTION =+
+(LOAD_BALANACE = ON)+
+(FAILOVER = ON)+
+(ADDRESS_LIST =+
+(ADDRESS = (PROTOCOL = TCP)(HOST = <server_name>)(PORT = <port>))+
+)+
+(CONNECT_DATA =+
+(SERVICE_NAME = <service_name>)+
+)+
+)+
+)+
Modified tnsnames.ora
PRUEBA.WORLD=
+(DESCRIPTION =+
+(LOAD_BALANACE = ON)+
+(FAILOVER = ON)+
+(ADDRESS_LIST =+
+(ADDRESS = (PROTOCOL = TCP)(HOST = <server_name>)(PORT = <port>))+
+)+
+(CONNECT_DATA =+
+(SERVICE_NAME = <service_name>)+
+)+
+)+
I Just delete the line "+(DESCRIPTION_LIST =+" and its corresponding closing parenthesis, I did this cause in the configuration utility log I saw this line:
+TNS parsing: Entry: DESCRIPTION_LIST [[Address: Protocol:(TCP) Host:(<server_name>) Port:(1521) SID:(<service_name>)]]+
So, if the applications were trying to connect to connection descriptor DESCRIPTION_LIST, the driver could not recognize DESCRIPTION_LIST as a valid one.
There is a lot going on behind the scenes when you work with Oracle Database as the repository, maybe there is some other way to address this issue, but it worked for me, hope it can help you too.

ORA-12154 connection error???

Hi
I have a "ORA-12154 TNS cannot resolve service name" error message. This occurs when i try to connect from a data connection wizard in MSWord for the purpose of a mail merge. I have checked the tnsnames.ora file and the SERVICE_NAME is the default XE, i type this as the server name into the connection wizard and receive the error message. Could the sqlnet.ora file have something to do with it? Is it actually technically possible to connect to XE from this wizard?
Thanks for any feedback
GC

In XE, I think that heterogenous services are not supported!

WRT54Gs newbie: no internet connection error message

Greetings,
I picked up a used WRT54Gs v7 and am tying to install it in my network. I'm wanting to have another wireless access point other than our iMac.
After looking through the "Guide Me" here on this site, I was able to get the ethernet connection working so the iMac connects to the internet. Although I can connect my laptop via the iMac's wireless point, I haven't been able to connect wirelessly to the WRT54Gs with either the laptop or my cell phone. On the laptop, the error is "No Interntet Connection.".
It also feels like my internet connection is slower through the Linksys than it was through a "generic" switch.
So, since I'm a newbie, what should my troubleshooting look like in order determine if there are settings that need to be adjusted or if it's simply a bum unit?
Thanks

Hi, how did you connect the WRT54GS router? Did you connect that router to a modem or to another router? How was that router configured? Is it acting as a DHCP server or just a plain switch? I would suggest that you upgrade the router’s firmware and to reset the router in order for the router to have a stable performance. You can then check on the link below for different ways on how you can configure your router.

ORA-12500 error while refreshing webi report

Hi All,
The problem looks simple, but i am struck with this. I am trying to refresh a webi report in BO XI R3.1, it throws the error "DBD: ORA-12500: TNS:listener failed to start a dedicated server process". It looks like there is no issue with the tnsnames.ora and sqlnet.ora.whar could be the other cause for this issue ? Any input will be appreciated. Thanks in advance.
Thanks
Raj

Hi,
   You need to fix up the issue on the Oracle D/B side first prior to testing on WebI.
   Try this link, it explains the error encountered in more details.
             http://ora-12500.ora-code.com/
   Simply put, can you use client tool (e.g. TOAD) to log into Oracle D/B using the same machine?
   Fix up the connection then WebI will work.

Ken

Error Ora-12500 when using dblink

Hi all,
I have a database that I can connect directly with no problem, but there's error when I try to connect to that db from another db by using dblink
(Select * from someTab@link_name)
The error is Ora-12500
(Sure that tnsname.ora file is OK, I meant SID that using in dblink)
What can I do to deal with this prob?
Thank you!

Mr_what wrote:
Thank you guys! Of course I've known what Ora-12500 means, google is always the first thing I do when have to deal with any prob.Then you should have run across the cause of the problem..?
The client (in this case, the PL/SQL code using the db-link) uses a TNS alias to connect to an Oracle Listener. Part of the TNS alias is specifying the database the client wants to connect to (e.g. using SID or SERVICE_NAME).
The Listener confirms that it services this SID or service (it needs to be registered with the Listener). It then "+hands off+" the connection to that database. It can do this either as a dedicated or shared server process.
In your case, your TNS connection does not request a shared server connection. So the Listener needs to provide a dedicated server to service your client connection. It does so by executing +$ORACLE_HOME/bin/oracle+ - using the settings for that registered database (which includes the +$ORACLE_HOME+ dir). It passes command line parameters to this process (typically +(LOCAL=NO)+ ), and other data via the call (such as the socket handle this oracle executable needs to use to communicate with your client session).
This is the step that fails. The Listener fails to create this dedicated process. It uses a specific kernel call (differs from o/s to o/s) to create this dedicated server (a process on Linux/Unix, or thread on Windows). This call is usually what fails and results in the error you see on the client side.
There can be a number of reasons why this failed. The usual two suspects are:
- the kernel not allowing the Oracle o/s user to create more processes as it has reached it resource quota
- invalid +$ORACLE_HOME+ and the call fails to load the bin/oracle executable process
I would first eliminate these two as the cause of the problem. If it is not caused by these, then I would enable listener tracing and troubleshoot a connection that results in this error. There are various levels of diagnostics that can be enabled for tracing. At the lowest level one can trace the actual calls made by the listener, including the parameters values passed.

Frustrating ORA-12500 error

Hi all,
HELP!!!
I'm using Oracle7.3 database server on Windows NT4.0 and workstation is Chinese Windows98. My PB6.5 application make two connections whenever login. The first connection always success (retrieve application general data) and the second connection (retrieve specific data) always have the ORA-12500 error msg after ~1min24s waiting. However the 2nd connection always success on second/third attempt.
Anybody know why???
I've already checked the server's listener.ora and workstations's tnsnames.ora files, they seems normal to me.
When I run OEM, I got the ORA-12500 error msg also no matter how many times I try. But it is very normal when I use INSTANCE manager, SCHEMA manager, SECURITY manager, STORAGE manager.
Please help!!!

Generally speaking one only sets the processes parameter, the sessions parameter will be automatically derive from the processes parameter.
However: each process constitutes a Windows thread.
You may be hitting the maximum number of threads for a Windows process (There is one Oracle process, and each dedicated server process is a thread).
What the maximum number of threads is I don't know, but I have never managed to have more than 200 processes.
You should investigate to convert to shared server.
Open_cursors refers to the number of SQL statements which can be opened by an individual session.

solution ?
Thanks for your help,

I guess this problem is from the Oracle Server,
One of these steps might work,
1. Stop and start the listener. (May be not a good idea.)
2. May be you are not using the same user/password to start the listener as the database instance.
You may use, system/manager.
Please get back for any further assistance.
