Questions on sqlnet.ora, listener.ora files in RAC environment.

Experts,
I've some confusion with below files in RAC environment.
sqlnet.ora
listener.ora
These files are available in two locations: <GRID_HOME> & <DB_HOME>.
My questions:
1. Why do we have two versions of files ?
2. When I query lsnrctl status from BOTH the homes, it says it is using listener.ora from <GRID_HOME> as shown below.
Listener Parameter File D:\app\11.2.0\grid\network\admin\listener.ora
3. What is the use of files which are in <DB_Home>
4. If you make some changes to listener using "Netmgr" tool, we expect it will update listener.ora in <GRID_HOME>. Interestingly, it is changing the contents of listener.ora in <DB_HOME> .
Can anyone please clarify it ?
Thanks in advance.

1. Why do we have two versions of files ? In the past, the CRS s/w did not include ASM (ASM did not provide support for cluster voting and registration disks). Thus the networking components such as SQL*Net and the Listener were not part of the CRS installation.
With Grid Infrastructure, ASM supports cluster voting and registration disks and is recommended to be used for that (as oppose to the old style of raw disks or using an external cluster-based cooked file system like <i>ocfs</i>). And with ASM comes the SQL*Net networking layer and s/w (such as the Listener). As ASM ships with Grid Infrastructure, it now also includes the same networking layer as what the RDBMS installation will. Thus both <GRID_HOME> and <DB_HOME> will contain the same networking components.
However, only a single Listener is for example needed. And that can only run from a single base location. So for operational use, only one version will be actively in use.

Tnsnames.ora, sqlnet.ora & listener.ora files are not exit

DB version: 10.2
Hello All,
I just joined the project and notice tnsnames.ora, sqlnet.ora & listener.ora files are not exit under $ORACLE_HOME/network/admin.
But still we can connect to the database,
From command prompt or via enterprise manager studio from client site.
Any idea?
OR
what is the best way to create above files in the existing database?

tnsnames.ora and sqlnet.ora are client side files, listener.ora and sqlnet.ora are server side files.
Listener.ora need not exist if using defaults and dynamic registration of services. It may be possible to cope without all those files, depending on the environment.
Is the database on the local or remote computer and how are you connecting (from sqlplus)?
Maybe you have a tnsnames.ora somwhere else? (Try using find command) Maybe TNS_ADMIN is set?

Tnsname.ora and listener.ora files in RAC environment.

Want to clear my concept regarding
tnsname.ora and listener.ora files in RAC environment. Is there any good notes on Metalink for that?

Any major differences of exadata database, listener, processes than regular RAC environment?

I would like to ask for any input regarding any major differences of exadata database, listener, processes than regular RAC environment.
I know now the exadata not only have SCAN listener, but a lot other listeners. can expert here provide more details?
Thanks

We will use zfs to do backups, is that possible for the initiband listener to communicate with ZFS? where I can find documents for zfs?
The SDP (Infiniband) Listener is for client connections connecting to the database on Exadata over the SDP protocol on the Infiniband network. You should use the Infiniband network to connect the ZFS to Exadata and mount the ZFS shares to the Exadata compute nodes using DNFS; but this doesn't use the SDP listener because there is no database connection originating from the ZFS you are just backing up your databases to it. See the "Oracle ZFS Storage: FAQ: Exadata RMAN Backup with The Oracle ZFS Storage Appliance (Doc ID 1354980.1)" MOS note for good information and references regarding backing up from Exadata to ZFS.
Plus how do I know we have exalogic? I dont think we have one, but is there a way to check to be sure?
Exalogic is another of Oracle's engineered systems. It contains integrated compute, network and storage - similar to Exadata - but is used for running application environments, specifically for fusion middleware (e.g. Weblogic) applications, instead of databases. It uses a ZFS storage appliance for the storage, as opposed to the storage cells on Exadata, and for virtualized environments uses the Exalogic Elastic Cloud software. You would know if you have one.
So basically after oracle engineer installed onecommand and created sample database, as oracle dba, we can dbca to create a database just like regular RAC environment? There is nothing specific on exadata perspective?
Yes... Oracle on Exadata is still the same RDBMS - same Oracle Enterprise edition with the RAC option. The Exadata difference comes with the hardware integration and the storage cell software... the database software is the same.
Another question is do I have to configure exadata specific parameters in order for all those features of smart scan, storage index, comrpession, etc work?
Some Exadata features are mostly "black box" and work without any configuration others may take some configuration or tuning to take advantage of. For example, storage indexes are created dynamically on the storage cells... there is not much you can do to control them. For smart scans you need full table/index scans with direct path reads. So you need to tune for direct path reads. HCC requires setting up your tables/partitions to compress at one of the HCC compression levels and using direct path loads.

Tnsnames.ora / listener.ora files on Oracle Standby Database

Hi I am configuring an Oracle Standby Database to my production system 4.7 and Oracle 9.2.0.4
My production server is: PR01
Database SID: PRD
Standby database server is: PRDR
Database SID: PRD
I have already configured the server to a standby database offline backup. Was generated the control files of the standby database and the database is in standby mode.
Now I will create a script to start the synchronization of offline redolog from the production server to standby server.
I have a question: in the document SAP Oracle Standby Database, tells me I should change the tnsnames.ora production server pointing to an additional entry disaster recovery server. The tnsnames.ora file must have two entries??? corresponding to a production server and another to the disaster recovery server??
In several links of oracle tells me I should configure listener.ora disaster recovery server that is true??
Guys my question is: where should I change my listener.ora and tnsnames.ora files?
Please clear my doubt.
Best regards,
Desiree

Hi Desiree,
The entry in your TNSNAMES.ORA is a nothing but a tns service, when you define archive log destination it will point to a service. This service's host name will be resolved in your tnsnsmaes.ora file.
Below is the eg of an entry in pfile:
*.log_archive_dest_2='SERVICE=<service_name> ARCH OPTIONAL'
Below is the entry in your tnsnames.ora file
<service_name>.WORLD=
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS =
          (COMMUNITY = SAP.WORLD)
          (PROTOCOL = TCP)
          (HOST = <DR_HOST>)
          (PORT = 1527)
    (CONNECT_DATA =
       (SID = <DB_SID>)
       (GLOBAL_NAME = <DB_SID>.WORLD)
So, your tnsnames.ora will have one entry for your host and the other for the DR host, i.e two entries.
Listener entry for the convenience when there is a switch over.

Where the init.ora , tnsnames.ora, listener.ora, sqlnet.ora

If client-side and server-side software are located in different machines, basically, init.ora and listener.ora are located in the server-side, and tnsnames.ora and sqlnet.ora are located in the client-side, am I right?

The confusion comes because, as stated earlier by Sanjay, a server could also be a client...

Configuring tnsnames.ora / listener.ora with HOST = localhost

Dear Oracle experts,
presently I'm trying to configure an Oracle installation on a Win2k server
to work with HOST = localhost entries in my tnsnames.ora and listener.ora.
I have to do that because I want to use that Oracle installation as an image
for several computers which will get different IPs and computer names.
My problem is, taht I only can configure my entries with a real IP adres (127.0.0.1 does not work ) or with the present name of the system but not with localhost or 127.0.0.1.
My listener.ora looks like below :
# listener.ora Network Configuration File: D:\oracle\product\10.1.0\Db_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SDU = 4096)
(SID_NAME = EMS)
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(PRESPAWN_MAX = 10)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost )(PORT = 1521))
The listener above lead to a
ERROR - ORA-12541: TNS:no listener
if I try to connect via iSQLPlus. If I exchange HOST = localhost with HOST = mydnsname the I can connect to the computer via isqlplus.
Is there any possibility to configure the listener and tnsnames without using real IP adresses ?
Best regards,
Daniel Wetzler

Different listener log file in RAC system

we have 4 nodes 11.1.0.7 RAC at redhat 5.1 linux system.
I just find there are two listener log file (listener.log; listener_nodename.log ) in each node.
I want to know which difference function is in both listener.log and listener_nodename.log?
When or which condition does node run( record data) in listener.log?
When or which condition does node run( record data) in listener_nodename.log
I saw the 3 node3 listener_nodename.log is wroking on and one node listener.log is workig on.
why?
Does some experts explain this point for me?
Thanks

I make some clears for this requirements.
we have a schedule backup and stores in ASM diskgroup in SAN.
As system admin and policy of SAN disaster recovery, we need to generate backup in a local file system.
in this case, we only backup database plus archival files in external file system. but I still saw snapshot control file is still put into default linux location.
I am not able to see this snapshot in external file system.
For SAN disaster recovery, do we need to save a control file snapshot in external file?
Can I apply BACKUP CURRENT CONTROLFILE TO DESTINATION "external file path" for SAN disaster recovery?
Thanks in advance!

Why remote listener is used in RAc environment

why remote listener is used in RAc environment

I'm sure there is something in some concepts papers anywhere on tahiti.
But as I'm as lazy to search as you are, I will try to answer:
local_listener is the listener which serves the instances which register to it (as local_listener).
remote_listener(s) should be all the listeners which serve the other instances belonging to the database.
every pmon tells all the local and remote listeners the load of the system where it resists.
In server side load balancing, the listener will redirect the client to the listener on the system with the lowest load.

TSNnames.ora & Listener.ora - Where do I find these files

Greetings!
I'm trying to connect from a SQL server to an Oracle server through the SQL management studio's Linked Server. I'm a bit confused as I get the error ORA 12504, which it says "Listener was not given the SERVICE_NAME in CONNECT_DATA" .
Where are these files suppouse to be? In the SQL server or the Oracle Server? I did a search in both servers and I don't get any results with the mentioned files names. What do I need to have them?
If someone could point me to an article or some guide, I would be in great debt as I need to figure this out preety soon.
Thanks!

YOu can find these files on oracle server under $ORACLE_HOME/admin/network directory.

Trace file in RAC environment

When creating a trace file, is it possible to specify a node where the trace file will be created? If so, please give example?
thank u

Like Chandra mentioned i dont think we can have a trace file get generated on a specific node. however you can do the following.. you can identify your trace files using..
ALTER SESSION SET TRACEFILE_IDENTIFIER ='MV'
Then you can use the 'trcsess' utility to bring down the trace files from multiple instances (if any) into one file and then run a TKPROF.
Refer to metalink Note # 280543.1 on how to use trcsess

Help with Listener.ora file location on Suse Linux

Hi
Ok, 2 scenarios
Scenario 1
Installed Oracle 10.1.0.3.0 on Suse 9.2, the location of the listner is: /oracle/dborafiles/application_name/instance/admin/netadmin/
Which is great, as this is where i want the listener and tnsnames.ora files to be under.
Scenario 2
Installed Oracle 10.2.0.1.0 on Suse 9.2 (using exactly the same method for doing the above instllation), and for some odd reason, the location of Listner and tnsnames.ora files are under:
/oracle/dboracle/orabase/product/10.2.0.1.0/network/admin/
This is the wrong location for me, I want the listner and tnsnames .ora files to be under same like scenario 1.
2 Questions:
Q1: why the listener.ora and tnsnames.ora files are diffrent location in Scenario 2 comapred to Scenario 1.
Q2: How do I correct it.
Note: the TNS_ADMIN in .profile is exactly the same for the above 2 installations, changed the applciation name and sid offocure, but all the same:
TNS_ADMIN=/oracle/dborafiles/applicatio_name/instance_name/admin/netadmin
export ORACLE_SID ORACLE_BASE ORACLE_HOME PATH
Can someone please help?

For a long time now, the tnsnames and listener files have been placed in the ${ORACLE_HOME}/network/admin by default. That is the location that the installer will create these files in.
Don't know why 10.1.0.3.0 install created the files in that folder. That is not the default behaviour in versions prior to this and versions after this.
Check the settings of the environment variables that were in effect at the time of 10.1.0.3.0 install.

Virtual address configure listener.ora and tnsnames.ora files on Solaris10

Hi,
I have installed Oracle 10g R2 on Solaris 10 U4 SPARC.

Using the command listener start it starts successfully.
Kind regards,
Daniel

The port in listener.ora nad tnsnames.ora are now the same - 1521
After this trying logining by Web page there is an error:
Error
Io exception: The Network Adapter could not establish the connection
When I run netca tool and I reconfigure listener netca change the IP address to sun3 which has 10.160.19.49. After this listener works fine and I am able to connect by Web page.
bge0 10.160.19.49 - is the base IP address
bge0:2 10.160.19.64 - is the virtual IP address
I want listener to listen on 10.160.19.64.

Questions on sqlnet.ora, listener.ora files in RAC environment.
