• 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-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:

  ADO error: 0x80040E4D
  Exception occurred in the Microsoft OLE DB provider for ODBC drivers:

  all will help much appreciated

  Thanks in advance

  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,.

  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

  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 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.

  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.

  (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?

• 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.
