ORA-12528: TNS:listener: all appropriate instances are blocking new connections

I'm working with OBIEE 11.1.1.5, with Ora DB 11.2.
Suddenly, the OBIEE is not accessible.
The logs showed that the issue is DB connectivity.
When I try to enter directly to the DB via sqlplus I get the error:

I tried restarting server, DB, listener, but nothing helped.
I've Googled and saw that I need to unregister some old connections, which were not closed correctly, i.e. entering DB and delete some records,
but I cannot login to the sqlplus.
I failed login as sys, system, scott - on the same error.
How can I solve this issue?

Does anybody have an idea about why this error is comming.
Note that we are using oracle 10g in a RAC environment with 02 nodes.
Thanks for your help.
Raitsarevo

I don't use SID in my tnsnames.ora, i use SERVICE_NAME and it's OK. May be someone who have configured iot's tnsnames made it wrong because there consultant installaing new application in our company and may be their tnsnames was wrong and causing that problem. Because in their application it always tries to connect in the database till connection will be established and may be it increase the database session number.
Isn't it and when session max number is reached may be database connection will hang.
Correct me if it is the case, we will have a look in their applivcation tnsnames configuration.
Thanks

TNS: listener: all appropriate instances are blocking new connections.

Hello,
when I start up my freshly installed developerday VB appliance, and try to connect to the database, following the tutorial in "Hands-on lab" - "SQL developer", as well as with any other attempt, the connection would not establish. I always get a message ORA-12528: TNS: listener: all appropriate instances are blocking new connections.
I cannot find any Readme or Tutorial which explains this appearance.
Weird, that obviously nobody else runs into this problem, otherwise this forum would be full of it. But isn't the VB appliance byte-for-byte the same for anybody?
Any ideas?

Hi Marco, thanks for replying. You can read the OS version from the lsnctl output. The OS of the host system of the Virtual Box is Windows7 64-bit. Hmm... "HOST=0.0.0.0" looks suspicious, doesn't it?

Ora-12528 all appropriate instances are blocking new connections

hi,
i get an error 'ora-12528 all appropriate instances are blocking new connections'
i have changed shared_servers parameters. from there itself i get the error

With zero substantive information about your environment, it is impossible to know for sure.
But, if you've just set SHARED_SERVERS=0, for example, and your tnsnames.ora has a line in it that says (SERVER=SHARED), then your client is demanding the use of shared servers which don't exist. You can therefore expect the sort of error you're getting.
The fix is to remove the explicit demand for shared servers in the tnsnames.ora. Just remove the line (or, not quite such good practice, set it to DEDICATED).

ORA-12526: TNS:listener: all appropriate instances are in restricted mode

Hi all,
I am trying to connect to Oracle10.2.0.2 in solaris9 as
conn sys/password@dbname as sysdba
but after this attempt it showing
ORA-12526: TNS:listener: all appropriate instances are in restricted mode
but if i connect like this
conn sys/password as sysdba
it works.
Can some one give me the solution for the same?
Thanks
Vipin

Hi,
When you want to connect to database there are majorly two kinds of protocols are involve
1. TCP and
2. IPC
when you are talking about <username>/<password>@<servername > then though you are on same server you are refering to TCP protocol and when you are talking about <username>/<password> then you are refering to IPC protocol
now here when you are going to connect to your database through
conn sys/password as sysdba
its working fine because you are using IPC and if you connect through
conn sys/password@dbname as sysdba
it will show you error because you are using Listener TCP.
So i think that you need to check your listener status and database status both and give the output.
Thanks

ORA-12526 : TNS Listener : all appropriate instances are in restricted more

I have configured configuration manager to listen to port 1610. When i try connecting to the database i get the above error. If i pass the configuration manager and use 1521 of the listener i can connect. The database is 10gR2.
The old data files were moved from a previous release . I had to open the database with the upgrade option.
Please let me know if any one has any idea about how we can get rid of this. Did not find much on metalink.

Is listener started successfully after changing the port to 1621?
did you change the port number in tnsnames.ora of the client?
Regards
Srinath

TNS-03505: Failed to resolve name
That's not the same error you reported in the thread subject ....
A TNS-03505 is very much like a 12154.
=================================
ORA-12154: TNS:could not resolve the connect identifier specified
This error means one thing, and one thing only. The client could not find the specified entry in the tnsnames.ora file being used.
As a follow-on to that statement, remember that when you use a dblink, the database in which the link is defined is acting as a client to the database that is the target of the link. So in this case, the tnsnames.ora file on the host of your source should have an entry for your target db, as defined in the db_link.
And for the umpteenth time ... this error has NOTHING to do with the status of a listener. The connection request never got far enough to reach a listener. If anyone tells you to check a listener in response to ora-12154, they are not paying attention, or do not understand how TNS works. This error is the equivalent of not being able to place a telephone call because you don't know the number of the party you want to reach. You wouldn't debug that situation by going to the other guy's house and testing his telephone, or by going to the phone company and testing the switchboard. And you don't debug a ORA-12154 by checking the listener. If I had a top ten list of "Incredibly Simple Concepts (tm)" that should be burned into the brain of everyone who claims to be an Oracle DBA, it would include "ORA-12154 Has Nothing To Do With The Listener".
=================================
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, with the default name of LISTENER, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners or to name the listener as if it belongs to a particular database. That would be like the telephone company building a separate switchboard for each customer.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
 (CONNECT_DATA =
 (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"

All Pipe Instances are Busy

I am running an Oracle Server 7.3.3.0.0 on an Windows NT4.0 server.
We currently are running about 30 small database instances on the NT box.
When I try to start an additional Oracle instance, I get the message "Could not start the service on xxxxxx. Error 0231: All pipe instances are busy". If I shut down one of the currently running instances, I can start another one, I just can't go over a certain total number of these services.
I have found some references that say that Oracle creates a Named Pipe ("ORAPIPE") and that it has a parameter called nMaxInstances which can be set to "PIPE_UNLIMITED_INSTANCES", but I can't figure out where to make this configuration change. Would changing my protocol to straight TCP/IP solve this issue? I have also found a parameter called "USE_SHARED_SOCKET" but am uncertain of where to set this.
Any help would be appreciated.

You may be running into an NT4 internal limit; I have checked the W2K resource kit though and can't find anything about max. number of pipes.

Can admin server be shutdown after all managed instances are started?

Hi all,
I'll like to ask, can the admin instance be shutdown after I have started all the managed instances? I'll restarted the admin instance whenever I need to preform admin duties, like application redeployment, configuration of the domain.
I reckon the answer is yes. But I'll like to know will my cluster still function? ie is there clustering function after I shutdown the admin instance?

Hi,
You can shutdown the admin server after all managed server instances are started. It will not effect working of cluster.
You will not be able to start any new managed server instance when the admin server is down, unless the managed server is starting in MSI mode.
Regards.
