Hello

First check if you can successfully tnsping database on the command line. Or you are able to connect Toad, so that when you call Toad, you can see the location of the tnsnames.ora it file use. Just set the parameter TNS_ADMIN at the user level, so that the other application will also use the correct tnsnames.ora file for database name resolution.

AMT: could not resolve the connect identifier specified

Hi guys, I have installed Oracle on Windows XP SP2 11.2.0.1.0 C:\oracle folder
I use the ORCL service to connect to the database using SQL more. I am connected yesterday and it was very good. Now I get this error:

ORA-12154: TNS: could not resolve the connect identifier specified

Of course, this error is related to the file tnsnames.ora and identifiers of Service and not correct SID.

Here are my tnsnames.ora

Have you worked from the link I provided? (I don't think you have time to do).

It is possible that your tnsnames.ora is corrupted by some weird characters printable somewhere. In some versions of the oracle, he might be sensitive to spaces vs. tabs. If in doubt, netca to add entries, rather than doing it by hand.

It can be caused by the location of the TOAD software. The have you installed under "Program Files (x 86)? If Yes, then try to reinstall in a different directory, media in the path name can cause problems.

Hello

I see just a glance on the tnsnames file you are missing at least one sign =...

You have

ORCL

(DESC...

You should have

ORCL =

(DESC...

There may be other issues too, but give that a try at first - you better run netmgr to allow oracle to create the file for you.

See you soon,.

I've learned to trust in your obfuscation you covered something important, or you are showing some apples and oranges. Error to declare you come from not being able to find referenced in tnsnames.ora entry, but the way you say you created your link db, you hardcoded the entire connection, so he never users tnsnames.ora.

I would change the definition of db_link

create the database link * _DBLINK

connect to the USER IDENTIFIED BY 'user '.

using "REM."

Then create an entry in your tnsnames.ora

REM =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP) (HOST = *. *. *. *)(PORT = 1521))

)

(CONNECT_DATA = (SERVICE_NAME = REM)

)

)

Also, use server name instead of the HOST = IP address

The closer looks that you can miss brackets final closing on your original definition.

I was saying about the environment variables defined by you on the server of informatica/dac under the .profile or .bash_profile as below:

TNS_ADMIN = $ORACLE_HOME/network/admin; Export TNS_ADMIN

ORACLE_BASE = / home/oracle/app/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/11.2.0/; Export ORACLE_HOME

ORACLE_SID = InstanceName; export ORACLE_SID

Path = $PATH: / usr/sbin: $ORACLE_HOME/bin. export PATH

LD_LIBRARY_PATH=.:$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH

CLASSPATH = $ORACLE_HOME/jlib: $ORACLE_HOME/rdbms/jlib. Export CLASSPATH

Here are some examples I mentioned everything. You can set them in the user profile from which you installed the server informatica/dac.

If it is a CAR Forum, try to set the value of the instance-specific SID for example: orcl11 or orcl12 or orcl13... try to connect to each instance. Sometimes the general SID does not recognize configuration

OBIEE 11 g, ORA-12154: TNS: could not resolve the connect identifier
HI forumer,

I installed obiee 11g and I am trying to connect to oracle 11 g db installed on the same machine. I am able to create the DSN using the tnsnames.ora, but the same details used with obiee work not and fails with:

ORA-12154: TNS: could not resolve the connect identifier

Appreciate any help in this.

Thank you
This is a change in behavior when we have 10g and 11g. In BI EE 10 g, there was no Oracle Client delivered with BI EE. Thus, BI EE will use your Oracle DB client host to connect to the database. Usually not a problem in this case. But in BI EE 11 g, the software itself contains a client of 11.2 DB. Thus, when you try to connect to the database using the repository or the BI server, it will try to find the tnsnames entry in the customer Oracle of BI EE 11 g instead of your database. There are 2 options to work around this problem

1. copy your tnsnames.ora {Oracle_BI1} \network\admin directory & {oracle_common} \network\admin directory (only the first is necessary because it is the ORACLE_HOME)

2. or instead of the source tnsnames.ora entry, use the full expanded tnsnames as shown below

(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 172.16.66.173)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = orcl)))

Both of the above will work.

New installation of XE 11 G SQL more ORA-12154: TNS: could not resolve the connect identifier

Hello
Just do a fresh install on a Windows 2008 (32 bit) "vrigin" XE 11 G. Everything seems to work properly can access through the front-end web, connect to Apex etc.
I want to upgrade from the Apex to the latest version if you need to run SQLPlus scripts... Impossible to connect, get the error message in the title.
Have done exactly the same setup and procedure on the computer laptop Windows 7 and Windows 2008 (64-bit server) without problem... no idea why this would be different?

OK solved this... Windows problem, but I don't know what. Automatic updates were turns off so decided to let the server itself up-to-date patch while watching in this... one of the patches installed seems to fix the problem, which I do not know if.

Hello
It is not related to Toad, check the TNS entry in your TNSNAMES.ora & make sure what is it pointing to the appropriate service name.

ORA-12154: TNS: could not resolve the specified connection identifier [10g XE]
Greetings

There are a lot of topics about this problem on the internet, but none of them deal with this issue properly, so I couldn't find a solution to the problem.

I installed: Oracle Database 10 g Express Edition

After that the installation was done, I opened the SQL command line
and I used the command "connect" to connect
I enter username
Then I entered the password

After a few seconds, I got the following error message:
ORA-12154: TNS: could not resolve the connect identifier specified

Screenshot of the error:

I installed this version of Oracle on Windows XP 32 bit and Windows 7 32 bit and I get the same error message when it tries to connect.

Why Oracle does not immediately after installation?
Are there other measures that need to be accomplished in order to make this work? If so I'd appreciate any help step by step, I was stuck trying to find a solution for days.

I was able to connect using the above command, but I would like to know why can't connect using a user name and password? I still cannot connect using a user name and password even after the environment variable.

The problem is that the normal user accounts are either locked, you use is maybe not the right password or they may not have the necessary privileges to establish a session (there are a number of reasons).

Since you are in the console database, you don't need the environment variable set. SQL * Plus Gets the location of your database in the registry.

Make the alter statement that I posted earlier for a user which you know that there is and we'll take it from there.
