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 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.
I have one query related to database connection from server to client.I have one database in the server and I want to connect from client.I set the tnsnames in client system as follows.
when i am connecting to my database in command prompt,sql * plus editor is it successfully connecting to the database but not connecting with the oracle client OEM.
but after connecting the LAN it is not connecting and also in the case when i am connecting to the internet through the USB datacard it is not connecting with the oracle client OEM.
how can i connect to database when the LAN,USB datacard connection.
I was trying to connect to a remote database from my client machine. Client machine runs a jsp code to connect to the database and execute a query. I have got oracle jdbc on my machine but still unable to connect to the database.
When checked in Google, i found that oracle connection manager has to be used to connect to the database from jdbc if the web server and database reside on different physical servers. But couldn't gather any further information regarding download and installation.
I do not have oracle connection manager on my system. I read in internet that it is shipped along with oracle 11g software. But i am not sure if that was the case in earlier version as well.
My question is where should i install oracle connection manager? (on database server or client machine) and is it possible to download and install only the connection manager as a stand alone so that i can connect to database from application?
I am getting the error TNS-12537. In the SQLnet.ora file, if no IP Address is listed everything works fine and the listener starts without any issue. But one of the Security requirements we have is, we need to list all the client IP address on the SQLNet.ora file. I checked the Windows Firewall services and it is disabled.

When i connect from client to server the client looks up for the host address and port number in tnsnames.ora and connect to it via listener.ora in server.Where does pga and sga come into picture here?
Also what is the role of sqlnet.ora in client?What will happen if i specify a different port for the instance in tnsnames.ora and listener.ora?
I am facing ora - 12537 TNS connection closed issue while I am trying to login into database.I have installed Oracle database 11g on windows 7 premium OS.
I have a JBOSS aplication server connect to database. When I tested on local, everything was ok. But when i test on real system , have a message "connection time out" on log file of app server while Oracle db still active. I viewed OEM, the system is executing the query :
"SELECT a.path songFilePath, a.BEAT beat from vp_song a, mst_my_album b "+ "where "+ "a.BEAT = b.BEAT "+ "and b.my_album_id IN "+ "(select my_album_id from (select my_album_id, ROW_NUMBER() OVER (order by my_album_id asc) "+ "R from mst_my_album where msisdn = ?) WHERE R BETWEEN ? and ?)";

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.
I would like to know that when the private network in oracle rac down, which is the preferable node in the cluster (cluster of 2 nodes) to takeover the cluster.
Can I set/get the failover policy to point to one node in the cluster?
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
# This file is actually generated by netca. But if customers choose to # install "Software Only", this file wont exist and without the native # authentication, they will not be able to connect to the database on NT.
i want to restrict particular ips ,for that i specified
TCP.VALIDNODE_CHECKING= YES AND TCP.INVITED_NODES=(IPADDRESS)
in sqlnet.ora file but whenever i connect to database from the particular specified IPADDRESS , the database allows the connection to happen ( doesnot restrict it),
i have a inventory system and trying to connect remote database one by one throught two static ips. If first ip is not ping then go to 2nd ip only when open the login.fmx page
I am getting beloww error very frequently in database log and not able to connect to the database.

I have two database TEST and TEST2 on same windows machine. In TEST database i have created one database link that access one schema in other TEST2 database. but when i passed select command to access object in TEST2 through Database link it is hanging indefinitely.
command that i have used to create Database link: create database link scott connect to scott identified by tiger using 'TEST2'
I don't believe it is using the TNSNAMES.ora entry for this, because when I take it out of there it still connects. I create a 10.1.0.5 database and copied the tables,etc to there. But I'm having problem connecting, getting "ORA-12154:TNS Could not resolve service name". Tried the following:
I new to this, but my guess is the other entry had the full path name..and this SERVICE_NAME does not. But then again I don't believe it looks at the TNSNAMES file. This NJZTEST is the 2nd instance on the NJZAINETTEST machine.
am getting this message when am connecting to a database :
ora-12519:Message 12519 not found;product=RDBMS80 facility = ORA
am not getting this message all the time, sometimes am connected without any problem sometimes i get this message and i have to try again several times until am connected
i searched the net and my database provider guided me to this log URL.....
