Networking And Gateways :: TNS - Make Any Configure Change In ASM?
Jan 30, 2012
My environment is setup like this.
+ASM instance and 3 DB instance.
DB_US
DB_Aus
DB_Gulf
there is just single listener running from +ASM binary handoff connection to databases .i have individual tnsnames.ora for each DB $TNS_ADMIN. this query work from server ,since i have REMOTEDB tns in DB_US $TNS_ADMIN.
SCOTT:DB_US> select sysdate from dual@REMOTEDB;
-- same query fails from a remote client.eg laptop.
SCOTT:DB_US> select sysdate from dual@REMOTEDB;
select sysdate from dual@REMOTEDB
*
ERROR at line 1:
ORA-12154: TNS:could not resolve the connect identifier specified
-- issue is resolved when i add REMOTED tns entry to +ASM tnsnames.ora
now question is , Can i make any configure change in +ASM side so that if it dont find a tns in its TNS_ADMIN, it should look for it in DB_US $TNS_ADMIN . eg : multiple TNS_ADMIN path, or ifile etc..

We want to configure HSODBC on HP-UX 11.23 for Oracle Database 10g R2 in order to establish a DB link from Oracle to Netezza.We have installed the ODBC Drivers too..Currently we have not done any configurations and we go via an AIX box to establish a link.We want to get rid of the AIX box and instead establish directl link towards netezza from HP-UX Box.
Does Oracle support have some guidelines or steps to setup HSODBC on Oracle database 10g r2 residing on HP-UX 11.23 towards Netezza?

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.

I have the following chunk of code, which could return no rows, one row or many rows. When it returns one or many rows the DBMS_OUTPUT.PUT_LINE prints out my values. When no data is found 'Hello' is not printed?
Suggest a way I can change the code to make the exception print when no data is found?
SET SERVEROUTPUT ON;
BEGIN
FOR prec IN ( select * from xxx.part_maint where drop_partition = 'Y' )
LOOP
DBMS_OUTPUT.PUT_LINE (prec.SCHEMA_NAME || ' ' || prec.OBJECT_NAME);
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.PUT_LINE ('hello');
END;

I have one production server with oracle 11g R2 DB. I have to change Server Hardware and thats why I have to install oracle 11g R2 DB on New hardware and test it. I had installed DB with software only option and copied the cold backup of production server. The hostname and ip address of both the servers are different. I had change the "db_domain" parameter into init.ora with the hostname.Now my question is that can the same db runs on the same network with different hosts. Change of "db_domain" parameter into the init.ora is enough or i have to follow some other procedure.

I installed Oracle Express on my Windows 2003 Enterprise server. And right off the bat I cannot connect to it via command line. I have googled and read many sites, but am still getting the same error, no matter what I do. I am newbie again (was a DBA in 1990...when I used to have the same error and fix it in seconds...not sure why this problem still lingers in Oracle) so most likely I am overlooking something. Below are my tnsnames.ora and liserner.ora files
tnsnames.ora
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = myservername.domainname.com)(PORT = 1521))
(CONNECT_DATA =

(SERVICE_NAME = XE)

My client get the error Ora-12514 when he tries to connect to the db.Well;
1) we restart the services: "OracleServiceOrcl" and listener but nothing changes
2) We restart the server and nothing changes
3) We checked the dump and he was done on March,26th. No db export yesterday. Is there any link with the clock change of this week-end (location of the server: France)?
4) The lsnrctl services listener command run successfully but it doesn't mention the instance ORCL.

I'd got this error, TNS-12542, address already in used on my multithreaded application.
After finding some documents about this error, it happen because other application used same port as my listener. But i'd assured that only my listener, but it didn't happen in the first running process, but after some processes (hundreds of processes).

We're deploying a new product release however this build uses Oracle 11G. We want to perform a side by side install for testing purposes. These are low usage systems so installing another Oracle build will not hinder the system.
We intend to test for a couple of weeks and migrate data, then uninstall the 10G. I'm in the process of installing 11G now, the 10G is up and running. I don't want to impact the 10G install. I'm installing 11G in /home/oracle/oracle11G directory. I would like to use 1 Listener.ora file. I've broken down the install bellow.
10G
SID "processing"
Oracle home /home/oracle/oracle10g
/mnt/Oracle/Oracle10GData
/mnt/Oracle/OracleRedoLog
11G
SID "processing11G"
Oracle home /home/oracle/oracle11g
/mnt/Oracle/Oracle11GData
/mnt/Oracle/Oracle11GRedoLog
I've copied the listener.ora file bellow.
LISTENER_PROCESSING =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST= X (PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 1.1.1.2)(PORT = 1521))
[code].......
LISTENER_PROCESSING2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = X (PORT = 1522))
[code]......
Do I need to specify the databasename for Processing2? Also the front end boxes (managers) are two different servers so Processingweb1 and processingweb2.

I want to connect ORACLE-11gR2 that is on linux with an MS sql server. DO i need to use some third party drivers like easy soft ? Can i configure the database gateway without any third party drivers ?
Secondly if my oracle is on linux, can i configure the gateway on a seperate windows machine(that will connect to linux oracle and ms sql server) as i have found the gateway installation setup only for windows version.

I would like to implement connect time fail over from my JDBC thin client. The client will try to first connect with dedicated connection mode, if the connection time crosses more than two seconds, then connection will be opened with shared mode. To implement this, I have put the following connection string in my JDBC URL. I am able to connect to database with this URL, however it seems fail over does not work. Is it because, my database listener is not configured with dynamic service registration. If I implement the dynamic service registration, is fail over going to work? Note, I want to fail over in the same database instance but with different listener.
(DESCRIPTION_LIST =
(FAILOVER = TRUE)
(LOAD_BALANCE = FALSE)
[Code].....

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?

We had an escalation wherein one of team members accidentally deleted an LDAP entry for a database. We use Oracle Net Manager to add/delete the connect descriptor.
Are there any logs using which we can find out as to who deleted the entry.

I have two related questions:
Scenario 1:
1. I have two remote Windows machines with database on each. One is Win 2003 Server (machine A) and another one is Win XP (machine B)
2. I can ping from A to B.
3. I can ping from B to A.
4. I can tnsping from A to B.
5. I CAN'T tnsping from B to A.
6. Windows Firewall on both machines are off.
What could be possible reason for point# 5?
Scenario 2:Now, the second part:
1. I had an unwanted entry in tnsnames.ora on B which I removed.
2. Then I restarted the listener on B. Actually, I wanted to restart the one on A to check if that resolves issue mentioned in point# 5 above.
3. I tried tnsping from A to B but suprisingly it is also giving "operation timed out" error now. So now tnsping not working from either sides.
I didn't make any changes in listener.ora on B, just stopped it and started again. Only change made was removing unwanted entry in tnsnames.ora on B.
Why does that affected database connectivity from A to B which was working fine previously?
NOTE: The two machines are connected through VPN using LogMeIn Hamachi. Hamachi assigns it's own IP address to each machine. Machine A is Windows Server 2003 and B is Windows XP.
