We've been administering a multiple instance production dB server with 3 different versions of Oracle installed.Currently, each of Oracle version had corresponding listener.Oracle 9i had 2 instances, 10g 6 instances & 11g 2 instances also.how I can integrate this 3 listeners into 1.

1. stop the listener as lsnrctl stop (default listener).
2. chnage the listener.ora and tnsnames.ora with desire port numbers (1526) as follows:-

I run test with not too big loading. select count(*) from v$sessions gets ~ 200 in maximum loading, but after half minutes I get this error in my logs. Each time, lsnrctl services show that all is right. It shows one service with one handler. I see nothing in alert.log. This is very strange, I know, and I'm sure that this is an actual alert.log because, I see there other events in actual time.

View 1 Replies View Relatedconnecting two oracle database in two different server.I installed Oracle 10g XE in both system.Both system act as Server.I need to connect both server using database link concept.
how to use the tnsnames,ora and listener.ora file for connecting both system.
ODBC--call failed.TNS:listener was not given the SID in CONNECT_DATA (#12504)
TNSname sets the SID. SQL*Plus is able to connect from the client Windows XP Proff using the same name. Access, on the same client, uses the same Oracle driver to connect successfully to other Oracle databases. These other databases show equal tnsname (different name and SID...)
ODBC Data Source Administrator configures the database and the test connection is successful.
Cannot set up a link from Access to the Oracle database. At some point, I have created a new Access database and it did let me connect, view the list of tables, and set up links to several tables, but the next day I could not open any of the tables and the complain was: ODBC--connection to 'MYDB' failed.
It seems that SQL*Plus passes correctly the SID from the TNSname but ODBC, when invoked from Access, does not. Yet, ODBC does it right for other databases.
Connecting Oracle to SQL Server via database link.
I am trying to connect from Oracle 10G to a SQL Server database. I have looked at the manual and i will admit that i am finding the documentation quite difficult to follow. There seems to be several options to use but none of the documentation describe how each option works.
As an example, i have been given the following information on the database i need to connect to (i.e. the SQL Server database)
- Username
- Password
- Database Name [lets assume the database name is data_extract]
To connect the above i made the following changes
$ORACLE_HOME/hs/admin/inithsodbc.ora
---------------------------------------
HS_FDS_CONNECT_INFO = data_extract
HS_FDS_TRACE_LEVEL = 0
$ORACLE_HOME/network/admin/tnsnames.ora
---------------------------------------
sqlserver.db =
(DESCRIPTION =
[code]....
Note: In listener.ora, i only added the last SID_DESC entry. I then went on and created the database link as shown below
create database link sqlservdb using 'sqlserver.db';
When i try to access a table i get the following error
sqlplus> select * from TESTTABLE@sqlservdb;
select * from TESTTABLE@sqlservdb
*
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from ORASQLSERVER
A couple of things i am not sure of:
- Where do i specify the username and password to access the sql server from the oracle db to the sql server db
- Having read around on the internet, i can see some people refering to a DSN datasource. I am told that the information that i have is all i need. Is this correct or do i need something else?
- The sid i specified in inithsodbc.ora and tnsnames.ora is actually the sql server database. Is this correct?
I am using oracle 11.2.0 in linux platform.i have created a listener for the asm database. and i am using non default port of 1525 whenever i go for lsnrctl>status always shows for the port 1521. i don't want the default port 1521 and i have changed the local listener as listener1 with port 1525 protool tcp in spfile and registered with the asm database.Is there any option to change the default listener as listener1.
also,everytime when i give lsnrctl>show current_listener it is showing "listener"
i have set the current-listener to listener1 and save_config listener1 and reloaded.After exit and enter lsnrctl>status it will show for port 1521 When i attempt to start listener1 every time. it will prompt listener1 is already running.
In one of our RAC envrionment, we have more than 15 databases in a server running in AIX Operating system.the Listener file I am able to find only one entry (SID). But while trying to execute lsnrctl status it displays all the 15 SIDs in the list hosted in the ser ver. Not sure how it works?
As we created another one new database in the database, where i need to add this SID in the listener.ora file to reload the listener.
1) I put attention that TNS write events into its log in too big frequency: ~ 10 time in second. I see that it is for every connection, but I assume that this no too good to performance.Is there some way to tell to TNS not to write event for every connection but only for errors?
2) May I to remove alert.log of DB? Or DB will make me problems with this?
3) How can I tell to my client connect directly to my instance rather than during TNS?
I have Oracle RAC 11g running on Red Hat 4 64 bit.
Which parameters are required in init file for 'Dynamic Listener Registration'? (for default port/ protocol). I understand that Local_listener is required only if we are using not default protocol, port.
Also which cases we need listener.ora file? I understand we need it for 'Duplicate Database' using RMAN as well as for 'Data Guard'. what else will need it?
I am having a problem getting my listener to start.

Is it possible to bind an Oracle Listener on 2 different interfaces on the same host?
My initial situation: I've set up a new VLAN in eth1.8 on our database server. There are 2 Oracle instances on this host. One instance was set up for the new VLAN, this works fine. The other listener stayed in the old network, because an other customer also needs to access this instance.
Now the customer wo was set up for 2 new VLAN can't access the other instance listenig on the interface eth0.
In short I have the following setup:
customer1: eth0
customer2: eth1.8 (VLAN)
listener1: LST1
listener2: LST2
SSID1: SID1
SSID2: SID2
listener1 is listening on eth0 for SID1
listener2 is listening on eth1.8 for SID2
This works fine.
Now customer2 needs to access SID1, which is configured on eth0, but customer2 is configured for eth1.8
So I need a listener for SID2, that is configured for both interfaces eth0 AND eth1.8.
i have created a listener for my db and register the service to it some 2 years back now i have checked it and it display as follows

I have a database up and running (including listener) on machine A. From that machine, everything seems fine. However, when I try to connect to it from another machine (say, machine B) on the network, the connection cannot be established (exact message: connection to database failed: The Network adapter cannot establish the connection).
I can successfully ping machine A from machine B. The machine A db is a default install (ORCL).
Is it possible the DB listener is not configured properly to connect to remote clients? On machine B, I have oracle tools such as SQLPLUS, Oracle Net Manager, and Net Configuration Assistant.
ORA-12518 Tns: Listener does not currently know of service
from application server using client 10g to connect our database.This problem happens only in application server and we tried from another server we can connect to database easily but problem only in application server.
this error since TNSNAMES and network are properly hosted since there no network disconnection betwwen database server and application server.
I have configured oracle listener at Non-Default port 1526.
Is it mandatory to mention LOCAL_LISTENER parameter at pfile?
LOCAL_LISTENER='listenerr_alias'
I just found out that the LISTENER I've creating with a password was with "-inherit" settings. Twice I succeeded in doing this, but it seems that it's not working when I tested it. Thus, I opted to get rid of it's listener.bak file and set the password again. Now I just can't stop it because of this error message: "TNS-01169: The listener has not recognized the password".
I've tried every passwords I made, and tried resetting it, but I'm not successful either, it's the same error message.My last option would be to restart the db Server (since the original listener.ora is already intact),
I have set password on the listener and set the local_os_authentication parameter to "OFF", whenever i start/stop listener through "lsnrctl" ,it works fine and asks for password but i can stop/start listener through windows services without giving any password.
what is the use of setting password on listener if any body can start/stop it through services utility in windows xp sp3.
My database link to the remote database used to work fine until the company VPN was updated for some security reasons. Now When I try to connect using the DBlink now, error comes up:
TNS 12541 no listener.
Checked the actual listener on the remote database(destination) and it is up and running fine. I am able to ping their machine.
ping <remote host> -works fine
tnsping<remte host> -fails
it comes back with error
TNS 12541: no listener
Nothing has been changed on both databases. The destination database can connect to our database without any issues(they can tnsping and use the dblinks to our database).
LISTENER ENTRY:
LISTENER =

None of the above should be the cause because there was no change been made on any of these.
