Automatic renaming hostname in tnsnames and listener.ora

Is it realy not possible to change hostname automaticly in TNSNAMES.ORA and LISTENER.ORA after installing an image-CD with Windows XP and Oracle11GR1. In Windows , there is a SID Change Tool and in Oracle?
Thank's for your help !
René

Again, take a look at running "netca /silent ..." with a response file.
Another (perhaps better) option would be to burn a cd with a software only install and that upon "activation" would then run a dbca noninteractive session to configure a database (I assume you want one, mentioning listener.ora).

Changin from IPs to hostnames in tnsnames and listener heads to TNS-12541

Hello.
In order to prevent problems and extrawork in future with planned IP changes, i want to change the tnsnames and listener.ora server configuration files.
Now they are using the IP in the HOST parameter, and I want to use the hostname. But it doesnt works:

Best Practices: tnsnames.ora and listener.ora

I would like to know if it is better to use the public ip / public hostname or the virtual ip / virtual hostname in the tnsnames.ora and listener.ora files on the servers and clients. I have seen examples where the vip is used for all areas, and I have seen examples where the public has been used in all areas. And of course even some examples where both are used. It makes more sense to me to use the vip, as that is what is failed over But what is the public ip used for if all connections are made to the vip?
Thanks

So if I was to create a tnsnames files on the servers, would I use the vip information as the host or the public information?
Would I use the same tnsnames files for the clients?
Would I use the vip or public address in the listener files?

Tnsnames.ora and listener.ora dissappearing

We are ruinning oracle 9.2.0.6.0 on Solaris 9 on a Sun-Fire-440.
We are having an issue where the above mentioned files (tnsnames.ora and listener.ora) keep dissappearing on this box.
We cannot seem to find anything in the unix logfiles or oracle log files, has anybody got any ideas on what could be causing this?
Mark Stewart.

If the files are being deleted then the timestamp on the directory which contains them will be updated ( given by ls -l ) . this would enable one to find out the time when they were deleted ( as long as nothing else in the same directory is being changed ) . It would be interesting to see if the deletes always happen at the same time , which would imply some automatic process , perhaps running under cron.

What should have in equal tnsnames,ora and listener.ora?

Hi forum members again I'm very new in oracle, and I'm trying to create a sucessfull net service name, using oracle net configuration assitant, but when I try to test it I got this error, .***"""ORA-12514: TNS:listener does not currently know of service requested in connect descriptor."""*** And I have read that tnsnames.ora and listener.ora should have some parameters in common, but exactly I don't know, Do you know what parameters should be? or The ORA-12514 problem , doesn't have relation with the tnsnames.ora and listener files?, If doesn't wich is the reason of this message?

OK, here we go ... extra long as I intend to bookmark this and make reference, as this is a very common question ... skip to the bottom if you want my guess to the solution.
Oracle Net Services (formerly SQL*Net, Net8, Oracle Networking) has two parts - the client and the server side. I'll discuss the server first, then the client.
1) Server, and specifically Listener:
The Oracle Listener is a monitor that listens for Oracle service requests on one or more ports. Usually this is on TCP/IP port 1521. When it gets an Oracle request from any network client, it checks whether it's in the list of Oracle Services for which it is monitoring. If found, it will contact that service, request a connection for the client, tell the service and client where and how to connect, and get itself out of the loop.
Notes:
a) It can listen on behalf of any number of services;
b) A service can be a database instance, an EPG service (the DBMS_EPG is the replacement for Apache in the database in 10gR2), an external job, etc;
c) One listener can listen on behalf of multiple database instances;
d) The services can be listed in the LISTENER.ORA or they can self-register;
e) If databases self-register, they use the initialization parameter LOCAL_LISTENER
f) If self-registering, the listener should be up before the database
g) Shutting down the listener will stop future connections, but has no impact on existing ones.
One frequent point of confusion - a connection request on the local machine may loop out to the network and contact the listener, or it may bypass the listener entirely and use a bequeath adapter. The 'beq' connection is the 'normal' connection by "sqlplus / as sysdba" or "sqlplus system/manager" on the local machine (note that no @instance was used ... in *nix, that is derived from the $ORACLE_SID environment variable)
In your listener.ora, you specify global_dbname=oracle.gentoo and sid_name=oracle. I assume therefore you can find an initoracle.ora or spfileoracle.ora somewhere on your system.
2) Client:
A client that wants to connect to an Oracle service uses the client side of the Oracle Net Services. The definition of client includes: any Oracle client utiltiy (SQLPlus, SQLLoad, Forms, Reports, etc.); an Oracle database instance that wants to make a external procedure call or a dblink; third party tools such as ODBC and JDBC.
In SQL*Net version 1 the connection was made by specifying the target in the connect string ("user/password@host:listener_port:sid") and that is also used these days by many JDBC drivers, especially the Oracle Thin JDBC driver. Oracle's Easy connection mechanism uses a similar variant.
Since SQL*Net Version 2, Oracle has supported the concept of alias translation. Basically it's very similar in concept to DNS - give it the name of the service and tell it where to find the translation table. The translation tables include TNSNAMES.ORA, ONAMES servers (deprecated in 10g), LDAP usng Oracle's OiD. The choice of translation table, and alternate order if the lookup fails in one, is stored in the SQLNET.ORA (if one exists).
Assuming TNSNAMES.ORA, the chain of events is:
- get the alias to look up (in your case NORACLE);
- if the SQLNET.ORA has a DEFAULT_DOMAIN setting, (often =WORLD) append a dot and that value to the alias;
- go to the TNANSMES.ORA file pointed by the TNS_ADMIN variable (environment or registry), or (if not set) the one in the $ORACLE_HOME/network/admin directory;
- look up the first occurance of the alias;
- if found, use the protocol specified to request a connection to the host, usin DNS to unravel the host to an IP address if necessary (in your case TCP/IP, to TUX) ;
- if host connection if made, connect to the listener that is configured for that port (in your case 1521);
- if listener is there, ask it for connection to the service (in your case, you are asking for instance 'noracle');
i if the listener knowwss about the service, it will hand off the request.
Your problem appears to be asking for instance 'noracle' in the tnsnames but listeneing for 'oracle' at the listener. Of course, I can not see any auto-registered instances which you would get from "lsnrctl status" on the server.

Tnsnames.ora and listener.ora

I am studying oracle and came accross
tnsnames.ora and listener.ora file.
Can any one tell me in simplified terms about these 2 files. what are they and what exactly they do?

When you are accessing Oracle over network you need a listerner service (usually on server box) and SQLNet or Net8 client on client machine. Listener.ora specifies the parameters for listener process and tnsnames.ora contains the SQLNet or Net8 connection informations about database server(s)

Dbua tnsnames and listener

Hi
When I use dbua to upgrade the database to 11g,
I notice that dbua doesnt create tnsnames.ora and listener.ora for the new 11g oracle home.
What is the recommended approach to resolve this?
1-)
Remove old listener from old oracle home
Initiate dbau
create new listener in new oracle home
create new tnsnames in new oracle home
2-)
shutdown listener from old oracle home
initiate dbua
copy listener and tnsnames files from old oracle home to new oracle home

Ora_83 wrote:
Hi
Apart from above question, I have another question.
When a database is upgraded with dbua, I notice that dbua will automatically create initilization parameters file.
How can it determine the values in new spfile? Does it copy the existing values from old spfile and remove deprricated ones and add new parameters automatically ?It will copy the values from the old spfile and adds new parameters automatically.

Tnsnames and listener

I was finally able to get the installation of Oracle DB 11 with client. But not clear how the tnsnames.ora and listener.ora work. Appreciate if someone can clarify following.
1 Why is tnsnames.ora is found both in the client and server directories. Why is it required on the server host?
2 listener.ora is only in the server host? Is that correct? Not required on client?

Trying to make it simple, I am answering the second question first
2. listener.ora is only in the server host? Is that correct? Not required on client?Listener.ora contains the listener service configuration (Name, DBName, Port, etc), Typically, it must exist only at the Server, and client connects to it using their tnsnames.ora definitions.
Why is tnsnames.ora is found both in the client and server directories. Why is it required on the server host?whenever it is required to connect to database using TNS, an entry in tnsnames.ora required be made. Since may tools (e.g. OEM) uses the tnsnames to connect to database therefore, it is necessary to configure the tnsnames.ora at server.

Is there a way to figure out what my oracle instance is reading in terms of tnsnames.ora and/or listener.ora file? According to the 10g docs, they can be found in a few places:
1. $ORACLE_HOME/network/admin
2. $TNS_ADMIN
3. in a global configuration directory, on solaris it is /var/opt/oracle.
How would I know which one my instance/lsnrctl is reading, aside from checking out differences in behavior?
Plus, how would I change where to look for the file?
thanks.

On Solaris you can use 'truss' on the binary and grep for all the open() calls to see exactly which files are being used or tested for in order. I had an issue once where a tnsnames.ora was being used and it turned out to be $HOME/.tnsnames.ora (IIRC). There are similar calls under Linux (strace).

TNSNAMES.ora and LISTENER.ora tuning

Hello!
I have a PE 8.1.7 installed.
When connecting fron SQL Navigator to Oracle DB I get an error message and sqlnet.log contains the following:
Fatal NI connect error 12538, connecting to:
(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=myhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=Andrei1.domain)(CID=(PROGRAM=E:\SQL Navigator 3\sqlnav3.exe)(HOST=MYHOST)(USER=kr))))
VERSION INFORMATION:

Why is it stated that TNS version is 8.1.6.0.0? Could it be that OracleOraHome81TNSListener was overwritten when I installed Designer 6i? What should I do in this case?

What are the wait events you are getting?
You got to be careful with SDU packet size, mostly the default is suitable for all the environments. If you increase the packet size to say 8K, you may be wasting the space if you are not able to utilizing all 8K. That would have an adverse affect as well.

Any advice will be highly appreciated.

Alex,
Next time when you post code or output or any configuration, enclose them between \ tags to preserve formatting
Your code or output \h4. Anyway, modify your tnsnames.ora file on your client machine and add this lm3dprd1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.58.44)(PORT = 1521))
(CONNECT_DATA =
(SERVER = dedicated)
(SERVICE_NAME = lm3dprd1)
(INSTANCE_NAME=lm3dprd1)

Why does itunes automatically close when I try and listen to a podcast?

When I click iTunes and then click on podcast it automatically closes iTunes. I can listen to my music but podcast won't play. why is this and how do i fix it?

If it's just a single podcast that's doing this it may be corrupt. If that's the case delete it and try re-downlading it. If it's all podcasts then you may need to restore your phone. Follow this guide to do this: http://support.apple.com/kb/HT1414, being sure to back up your phone at step 6 (you will be able to restore your phone to this backup at the end of the process).

SphinxIf they are both on the same server, why do you specify two different IP addresses?
And "10.2.2.x" is not avalid IP address. That "x" must be a number in the range 0 to 255.
