Error ORA-16724: could not resolve the deficit for one or more databases in waiting

I came to work today with the following error is displayed:

February 5, 2014 01:27:19 error ORA-16778: make the mistake of transport for one or more databases.

Looks like this error disappeared but now I have the following error:

February 5, 2014 11:52:40 error ORA-16724: could not resolve the deficit for one or more databases in waiting

I did some research on the forums and I think I need backup and restore, but I'm not sure.

Here are some questions that I saw others asking in the forums:

PRIMARY:

Select max(sequence#) from v$ archived_log; -24589

Select current_scn in the database of v$. -871568619

SECONDARY:

Select max(sequence#) from v$ archived_log; -24589

Select max(sequence#) from v$ archived_log in case of application = 'YES '; -24562

Select current_scn in the database of v$. -870987797

Select * from v$ archive_gap;

Thread # Low_Sequence # High_Sequence #.

1 24563 24563

Looks like everything is working, but the error is still appearing in OEM primer.

The issue ended up being with the control file. I followed of many blog posts on how to roll forward the database before and they all said to restore the control file before you recover the database. I followed this paper: http://docs.oracle.com/cd/B28359_01/server.111/b28294/rman.htm#CIHIAADC and it worked as expected. The old control file has had 6 data files that were in a different place than the others. The new control file, I created the primary had all the files of data in one place. After correcting the control to point to the locations correct datafile all started working again.

ORA-16783: could not resolve the deficit for the database
I have two databases emadb and emadbdg, governed by Data Guard. emadb is currently principal. emadbdg is currently pending physical.

ORA16783 - cannot solve the gap for the database is one I think, is the origin of the problem. Anyone can help solve the problem below. Logs attached.

It is misleading to the column sequence, sequence of real number is 65 series, but it's beyond. Have you restored any old backup with the incarnation?
When you perform incremental backups, is the current_scn in the two primaries and Eve was balanced?

And the sequence number * 29 * is transferred from the primary to the standby (or) he has been removed from the primary?
Perform the two methods.

(1) SQL > alter system set log_archive_dest_state_2 = 'reporter ';
(2) conduct 3-4 log switches
(3) SQL > alter system set log_archive_dest_state_2 = 'enable '.

and displays the alert log database and backup files.
And you mentioned the hostname in the entries of the listener, if this entry is added in/etc/hosts? otherwise you can use the IP address instead of the host name and then reload the listener.

second method
(1) copy archives missing from primary sequence of 29
(2) place manually and then perform a recovery
or
(3) retrieve manually

And update with your conclusions after all these lists.
Thank you.

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

Hi all
We need to make an entry in the tnsname.ora file in a local database to connect to the remote database using db link?
Here is my code: -.

using '(DESCRIPTION =)

After the creation of the DB connection when I'm trying to run select 1 of dual@***_DBLINK
He throws me an error ORA-12154: TNS: could not resolve the connect identifier specified
Am I expected to do an entry in the file tnsname.ora for "REM". I don't remember making any changes in the file tnsname.ora for the creation and access of the remote database via dblink.
Help, please.
Thanks in advance.

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.

Hi friends,
We do face-down question when executing the execution Plan in DAC for full charge. We are working on the project of modernization of the OBI Applications and my client has worked on this environment is a few days. Before this, they load to the source 'EBSTST' instance and now changed data for instance 'EBSWKLY '. We have changed the details of connection under the tab 'Physical Data Sources' DAC. Test the connection Source and target are good. We have added input TNS of EBSWKLY in the path: u01/app/oracle/oracle11g/product/11.2.0/client_1/network/admin.

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

ORA-12154 tns could not resolve the specified correct identifier

I am facing the following problem:

labVIEW 2012 32 bits 64 bits of Windows 7, 10.2.0.1.0 oracle client (32-bit).

I created a DSN from Data Sources (ODBC) (32-bit version of what in % windir%\syswow64\odbcad32.exe) pointing to an instance of Oracle 10 g.

I have test the DSN in this way (IE. Data sources (ODBC) and the connection is successful (which means that the tnsnames.ora is correct).

I use the "DB tools Open Connection.vi" in order to get connected to this database, passing as parameters the DSN above, the user name and password.

I get the error:

Hello everyone.

I already solved the problem (work until late Saturday).

the solution was to install the latest version of the Oracle customer, namely: Oracle 11 g Release 2 CLIENT for Windows 32 (11.2.0.1.0).

Now everything works OK.

I also tested in Windows 7 32 bit (the .vi even and the same Oracle client). This will also OK.

Thans a lot.

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.

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,.

URGENT: ORA-12154: TNS: could not resolve the connect identifier specified
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error occurred. [nQSError: 43113] The message returned by OBIS.

[nQSError: 17014] Cannot connect to the Oracle database. (HY000)

(1) I have TNS entries under MW_HOME/OracleBI/network/admin
(2) TNSPING works fine.
(3) source updated JDBC in place on the side WLS...

What should I do?
Show complete exception stack trace. This does not seem to relate to WebLogic. The WebLogic console
view running data source? In fact you use WebLogic DataSource?

Hello

«I installed on my laptop with win 7 Oracle Database 10g Release 2 (10.2.0.1) Express Edition for Microsoft Windows, but when I tried to connect with Toad for Oracle Freeware 10.6 I get the following error ' ORA-12154: TNS: could not resolve the connect identifier specifier (XE)» I read on the forum that the problem comes from the wrong configuration of the AMT.

Can someone tell me what is the problem?

Best regards
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.

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:
http://I35.Tinypic.com/14o26g7.PNG

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.

error 105: could not resolve the address of the DNS server

error 105: could not resolve the address of the DNS - why what it means and how to fix it?

I get this message usually one or two times a day, usually in the afternoon, when I try to go to the internet. I can use IE or Google Chrome - always get the message.

Eighty-five percent of the time, I get very well connected. But when I get this message, I unplug the cable modem from the power strip, wait 10 seconds, plug it in and after a few minutes, I'm connected to the internet. How to solve this regular error?

Hello

You have to contact your internet provider (ISP) as DNS are usually associated with ISP. Have they reset their modem or router not only feeding cycle?

Did you try the following steps below

Start > all programs > Accessories > command prompt. Do a right click on it and "Run as Administrator". Type follows and press ENTER: ipconfig/flushdns
