Oracle 10g listener hang

Dear Expert,
I manage to create database 10g version 10.2.0.1 and listener using DBCA initially working . But few day later, when i try to lsnrctl status to check listener it was hang. I try to kill the listener process and run lsnrctl status but it hang forever. I using the netca to recreate the listener but hang as well... Do i need to patch the db in this case.
OS ... Solaris 10 spar 64 bit.

Oracle 10g listener standard

Hi all,
I am trying to define Oracle 10g listener standard in my organization.
We have 60 Oracle 9i databases in an AIX node. We are planning to upgrade these database to 10g. During upgrade we want to configure the listeners according to our standard.
Now we are not using dynamic registration for Oracle 9i databases. So there are 60 seperate listeners that always try to establish connections to the database even if the database is not up. This leads to server performance problems when the applications overload the server with connection attempts when there are hundreds of processes waiting to connect.
After upgrade, we want to make all databases register with a listener for performance problems. But one listener per node can be too risky, maybe we can register a database with more than one listener.
Also, there are some reasons for shutting the listener down:
1. Cold backup
2. Apply patches
If we use only one listener per node, for cold backup we would shut down the listener and then no clients would connect to the databases.
After these explanation, I am wondering if we can mix both reducing the number of the listeners for each node and using load balance for all databases.
Do you hane any ideas, suggestions?
Thanks,
Fatma

With Oracle 10g and RMAN there is no longer any reason to be doing cold backups.
I'd run one listener per node. If this is too risky than a single database instance is also too risky and you should be investigating other high-availabilty solutions. RAC isn't always the answer.
Connection manager might also be useful in your environment.
Cheers,

Oracle 10g Listener XP pro need to be restarted ...

Hello all.
Here is my problem. I have oracle 10g installed on a computer with Windows XP pro Sp1a. Every thing work fine despite 1 point. When the computer is restarted, a small software starts the different Oracle Services (Oracle Database Service and listener) and wait for the 2 services to be in the state "started". After startup, the two services are in the state "started" but, sometimes, I can not get connected to Oracle. In the listener log, I have a message "TNS-12514: TNS:listener does not currently know of service requested in connect descriptor".
To solve the problem, I have to restart either the listener service or the oracle service or both of them.
My problem is that this computer must be an "auto starting system".
What can I do to solve this problem ???? Is there a specific order to start the process ?, Should I put dependency between them ???
Thank for your help.
D. GARRIVIER

If you use, as I think, dynamic service registration (no SID_LIST in Listener.ora for your DB), then it would be better to start the listener before the Database. If not, the registration could take a few seconds (or minutes). Anyway, if this is the problem, you should be able to connect after a few seconds (or minutes).

Does anyone know what might be causing this? I have been having a hard time getting anything from Oracle installed on this Itanium machine and am wondering if Oracle really supports it.
Thanks for any help.

Jeff,
You should post your database technical questions in the database forum for an appropriate response: General Database Discussions

Oracle 10g Listener sees to stop - all was OK then a few days later it stop

lsnrctl status gives an error TNS-12560 TNS protocol adapter error followed by 32-bit windows error: 55: unknown error
All is fine after a reboot of the server but the listener will not respond to anything such as LSNRCT STOP - the only solution is a reboot of the windows server that Oracle 10g is installed on.

I cant understand this - if it was a configuration error somewhere the listener would most likely not start in the first place - but for it to start OK and then fail seems strange - and then there is no actual error written to the listener.log.

This is a problem with non-paged memory allocation on Windows,see on metalink:

Oracle 10g Database Hanging twice a day

My database server has 10g with MS 2003 server as OS.
Twice a day the database hangs and does disconnects all the users from local and remote locations.
Current SYSTEM tablespace has a size of 470 MB and is 98.86 in use, when I try to add another datafile as 'SYSTEM02.DBF' in the same path where other system data files are, I kept this operation running during weekends but datafile was not added.
Has it anything to do with the MS 2003 server no. of users.
Any other suggestions for SYSTEM Tablespace to be free.
Please reply.
Thanks

When we start using system with 4-3 users at a time, after few mins or few hours, that application slow down or hang.
and then after we are not even able to get a simple HTML page. It also affect the other applications as well, which are deployed on that server.
We have tried our best but not able to find what the exact problem is. Even we have used visualVM and Jconsole to monitor the application.
When application hang, we had found that there were 6,959 Loaded Classes, 200MB heap size, CPU usage 20%.
We have set the heap size to 2GB.
Another thing is, some procedures take 20sec to 2min to execute. But does this affect the application such a way that it goes hang?
Please help to found out the problem.

Oracle 10g listener processes on linux

Hi,
We have databases (10.1.0.3) running on linux x86 (RH AS3) and Tru64 unix.
I have noticed on linux that there are a number of processes for each listener whilst on Tru64 the listener has only one process.
Can anyone explain why linux has these extra processes?
Thanks
Mark

Hi Mark,
I've the similar issue on linux and solaris.It's a bug in 10g .There is a patch available for it.Apply Patch 4518443 for the problem .Or else you can do the work around like adding this text to your listener.ora file will fix the problem. SUBSCRIBE_FOR_NODE_DOWN_EVENT_<listener_name>=OFF

yes you can try copying the contents in the server first and then try the installation, if there is any problem with the disk, it will throw an error during copy itself.

Oracle 10g Listener Port Changes after every Restart

Hi All,
I have installed Oracle10g in my Laptop and was working fine till last week, but now when I start the Listener, it is starting with different port number other than the default port 1521. ( For example first time Listener started with port number 3110, then after restarting the Listener it becomes 3313, and so on) That means server is assigning different port numbers on every time when the listener starts.
Because of this I am not able to connect to the database.
How to make the Listener port as default 1521 permenantly.
Please help.
Regards

Hi,
Can you please check the listener.ora file? Do you have the port number
mentioned as 1521 as below:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = my_server_name_fully_qualified)(PORT = 1521))

Info about Listener for oracle 10g and 11g installed on single systm

I have installed oracle 10g n 11g on my system. I have question regarding oracle listener.
oracle 10g , Listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = kankala.kalyan)(PORT = 1521))

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = kankala.kalyan)(PORT = 1522))
my question is why the listener's names are same even though thy are on different ports?
and for people worrying, why i have installed 10 n 11 is
Initally only oracle 11g was installed on my system. Later, I was learning forms for first time and i have to connect to database frm developer suite 10g. so i installed oracle 10g database.

The names are the same because that is the way you created them.
If you want to make a change use NETCA to drop and recreate one of them.
Just make sure you've defined ORACLE_HOME correctly before you do it.

Oracle 10g tns listener

i have installed 10g database on the same server on which 9i already exists. i did it on two machines and on comp1 everything is going well, but on comp2 (which is main server in our company) i can't connect to database i created during the 10g installation. when i try to run enterprise manager console, i'm asked for host and/or database username and password, and when i enter these things i still can not run EM. after few attempts i figure it out that there might be a problem with listeners (i found it on net) and i found out that on comp1, with which i have no problem, oracle 10g listener is running (control panel->admin tools->services), but on comp2 9i listener is running, and there is no 10g listener listed in services at all, so this could be the problem which i don't know how to solve. what should i do to register or do anything else, to have 10g listener listed in services to make it run???? if i'm wrong about listeners, tell me some other ideas and solutions to work it out.
thanks a lot to anyone willing to help !

Hi
Stop and disable the 9i listener service and to create a 10g listener with the Net Configuration Assistant (Start -> Programs -> Oracle 10 Home -> Configuration and Migration Tools -> Net Configuration Assistant). As you saw on the other macine, the 10g listener will register the 9i and the 10g databases.

Oracle 10g DB listener does not work.

I am in a terrible situation.
My oracle 10g db listener often hang without any sign.
For example , sometimes user sql select one minute ago , then the database could't be conected next minute .

I have to kill process then start listener.
I try to find out what for , but i am don't know how to do .
May any one tell my why or how ?
Thank you .

Thank you .
I find how to happen the problem . It should be bug 4518443 .
Now i have another question .
I want to apply patch ,but fails.
following is my command line :
[oracle@localhost ~]$ opatch lsinventory
-bash: opatch: command not found
When I cd $oracle_home/OPatch , i find opatch file.
Iam not sure why i can't apply patch .
