Quote:

ORA-12154: TNS:could not resolve the connect identifier specified
Cause: A connection to a database or other service was requested using a connect identifier, and the connect identifier specified could not be resolved into a connect descriptor using one of the naming methods configured. For example, if the type of connect identifier used was a net service name then the net service name could not be found in a naming method repository, or the repository could not be located or reached.
Action:
- If you are using local naming (TNSNAMES.ORA file):

- Make sure that "TNSNAMES" is listed as one of the values of the NAMES.DIRECTORY_PATH parameter in the Oracle Net profile (SQLNET.ORA)

- Verify that a TNSNAMES.ORA file exists and is in the proper directory and is accessible.

- Check that the net service name used as the connect identifier exists in the TNSNAMES.ORA file.

- Make sure there are no syntax errors anywhere in the TNSNAMES.ORA file. Look for unmatched parentheses or stray characters. Errors in a TNSNAMES.ORA file may make it unusable.

- If you are using directory naming:

- Verify that "LDAP" is listed as one of the values of the NAMES.DIRETORY_PATH parameter in the Oracle Net profile (SQLNET.ORA).

- Verify that the LDAP directory server is up and that it is accessible.

- Verify that the net service name or database name used as the connect identifier is configured in the directory.

- Verify that the default context being used is correct by specifying a fully qualified net service name or a full LDAP DN as the connect identifier

- If you are using easy connect naming:

- Verify that "EZCONNECT" is listed as one of the values of the NAMES.DIRETORY_PATH parameter in the Oracle Net profile (SQLNET.ORA).

- Make sure the host, port and service name specified are correct.

- Try enclosing the connect identifier in quote marks. See the Oracle Net Services Administrators Guide or the Oracle operating system specific guide for more information on naming.

Michel

thanks for the above help

i tried the same problem and error diminished

but instead of using database name i used whole connect descriptor in the tnsname.ora

like
rman target sys/pwd@(
(description =
(address=(protocol=tcp)(host=nineva)(port=1383))
(connect_data=(rpc=on))
)

and it worked fine now please tell me where i might have been mistaken even my tnsname.ora is perfectly ok

please reply

Are you sure? Some times it seems OK but it is not (like a "}" instead of a ")" hard to see the difference at first sight)
Are you sure you use the correct tnsnames.ora (check TNSADMIN variable, local tnsnames.ora, in /etc or /var/opt/oracle, in ?/network/admin)?
Are you sure you have no other naming methods in sqlnet.ora?

All the points I mentioned and you didn't answer.

For the other errors, my telescope is broken and I can't see over your shoulder.

sorry for not clearly mentioning my problem really sorry for
that

now practically describing problem is

connection to the target can be made as follow to my test database

rman target sys/pwd@test

is this will suffice? i think ok

but it give me error like
Recovery Manager: Release 8.1.7.1.1 - Production

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00554: initialization of internal recovery manager package failed
RMAN-04005: error from target database: ORA-12154: TNS:could not resolve service name

now if i try to connect with as follow

rman target sys/pwd@test(description=(address_list=(address=(protocol=tcp)(host=1##.##.##.#)(port=1521)))(connect_data=(sid=test)))

then it work fine

so it's cumbersome to type this all the time , so it's better that if i could simply write

rman target sys/pwd@test

finding solution to this problem is cumbersome as i am still a student on training and now my job is started in the same company
this child is new to this database environment , can u please help me out in this please.....

It depends on what your really want to achieve.
Point in time recovery is not a goal in itself.

sir my rman version was of 8.1.7.1.1 and database version was 9.2.0.4 which seems to me as a problem as i switched to rman 9.2.0.4 my problem was solved now i can keep myself busy with the backup and recovery

thanks sir for all your help

and another problem now i created two user bhavin and malvika on my test database

now when i tried to drop both of this user but it had taken up more than hour so i had to stop that abnormally

now when i try to drop that user again i get the message
'can not drop currently connected user'

but i can not see any information of the user in v$session

finally getting frustrated i shutdown database and restarted database and dropped that user

but this is not the optimal solution , i wan't to drop such user without shutting down my database

is there is any solution for that, please help me out in this

Dropping a user lead to a multiple a internal small transactions.
Aborting in the middle may in inconsistencies in memory structures. And it seems you are in this case.
I don't see no other way than to restart the database to solve this.

Start a topic per question.
This one begins to be a real mess unusable for anyone else.
What is the relation between "error in tns connection", drop user, backup tables, error in database creation, "no such file or directory", tablespace recovery...
