• Link between Oracle database 10g and Oracle database 11g database

  We have a database from Oracle 10 g to which connect us with SID = mod

  The TNS names file is present in the directory Oracle NETWORK\ADMIN on the development computer contains the following two entries among others

  MOD =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = 10.70.10.23)(PORT = 1521))

  (ADDRESS = (PROTOCOL = TCP) (HOST = 10.70.10.21)(PORT = 1521))

  )

  (CONNECT_DATA =

  (SERVICE_NAME = mod)

  )

  )

  NEWMOD =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = 10.70.10.7)(PORT = 1521))

  (ADDRESS = (PROTOCOL = TCP) (HOST = 10.70.10.9)(PORT = 1521))

  (LOAD_BALANCE = yes)

  )

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = MOD)

  )

  )

  In the SQL client we can log on to the mod and newmod each with its own username and password.

  To create a link of database as follows

  CREATE newmod CONNECT TO DATABASE LINK Public user1 IDENTIFIED BY password1 USING 'newmod ';

  the database link is created without problems.

  However, in trying to retrieve data from tables in the database that uses 10.70.10.7 and 10.70.10.9 using a command like

  Select Column1 table1@newmod;

  We get the following error:

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

  How can access us the tables at the entrance to tns newmod because it resides on a server 11g, while tns mod entry is on a 10g Server? (both use the same service name, but are located on different ip addresses)

  Your help is very appreciated.

  Have you set TNS_ADMIN variable? Check if you have any additional TNSNAMES file. ORA in your ORACLE_HOME files.

  Point A of TN-entry NEWMOD to a host. Load Balancing is not needed.

  Try to create the dblink with the connect descriptor.

  create database DB_TEST link to connect to SCOTT

  identified by "password" ' (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 10.70.10.9)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = MOD)))';

• Drop the link of database in oracle 11g

  I created a schema with the name of sapsmc which has all the privileges, then I created 1 link of database. Now, I want to drop this database link, but I can't able to drop this error.

  «SQL error: ORA-00604: error occurred at recursive SQL level 1 ORA-20101: Sorry, can't remove any object without the permission of live database SAPGateWay.» ORA-06512: at the level of the 5 00604 line. 00000 - 'error occurred at recursive SQL level %s' * Cause: an error occurred during the processing of a recursive SQL statement (a statement applicable to the internal dictionary tables). * Action: If the situation described in the next error on the stack can be corrected, do so; otherwise contact Oracle Support.

  Then I tried to delete the user SYS, while doing this that I got below error.

  SQL error: ORA-02024: database not found link 02024. 00000 - "database link not found" * Cause: database to remove link is not found in the dictionary * Action: correct the name of the database link

  Please help me I appreciate your efforts.

  ORA-20101: Sorry, can't remove any object without the permission of live database SAPGateWay.

  There is not much we can do about it.

  It is an exception defined by the user, probably from a FRONT DROP trigger defined at the level of the database, which prevents people from dropping objects.

  Contact, one who is responsible (DBA?) about how to proceed.

• Oracle Discoverer 4i (Portal db - oracle 8i) connectivity with database 11g problem

  Hi all

  We have oracle discoverer 4i with Portal db (oracle 8i).

  Connect to external databases by using links in the portal db db and reports will use the link db to retrieve data from views in external databases.

  External databases, we have been connecting is oracle 10g version and now we have improved these databases to version 11g.

  Now I have a created a new database link to this 11g database and I have created a new EUL in the portal to connect to this database 11g.

  But when I try to create a report using the discoverer of this new EUL after login for the discoverer we get an "Unable to connect to the database" error.

  We all have the privilege of necesscary to the user and the new database link works perfectly well. (when we try to query directly using SQL as database portal using this db link the query works perfectly).

  I'm not sure if it is a compatibility issue in accessing an 11g database since oracle disk 4i.

  Can any advise if this is the case and if there is no work around for this?

  Kind regards

  REDA

  You say that you are having problems with a link of database from 8i to 11 g (pl exact position of 4-digit versions)? If so, expect as database of links between these two versions are not supported. Is there a reason you can't pass the portal of databases of at least 10 g 2?

• 1Z0-054: Oracle Database 11g Performance Tuning Expert

  I intend to give the exam 1z0-054 for the certification, "Oracle Database 11g Performance Tuning Expert".
  
  The path to Certification indicates that, if you are 'OCP DBA 11 g' then you can directly take this article and there is no requirement for training instructor. Therefore, I decided to prepare my own. Can someone guide me on study material and landfills?

  Therefore, I decided to prepare my own. Can someone guide me on study material and landfills?

  First of all, the word "shock" has a precise meaning. It is short for "landfills of brain", which are illegal and can cost you this certification and all others you have taken.

  http://blogs.Oracle.com/certification/entry/0477

  Second - there is currently no study guide or a specific book to this certification at the moment. I write the study guides and this one is actually next on my list when I finished the current book to * 1Z0-117: Oracle Database 11 g Release 2: SQL Tuning *. I have a guide for 1Z0 - 054 before sometime in may more likely. That said, I have a few links for legal study on the companion Web site material for my series of guide to the subjects for this exam. It also has links to the Oracle documentation that contains the information you need. Once I have started writing the book review, links will develop quickly because I research for her themes and links to the documentation could extend as well.

• Migration of database 11g (11.2.0.1) to 12 c (12.1.0.2)

  Hello

  I have two RAC environment of node on windows 2008 R2 with Oracle 11 g (11.2.0.1) 64. At the same time I built another environment of 12 c (12.1.0.2) software install only on windows 2012 64-bit using ASM. It is once again two-node RAC

  I want to migrate the database 11g (size about 400GB) on the 12 c environment.

  My preference is to use RMAN. Could you get it someone pls let me know what is the best way to perform this migration.

  Note: I don't do this in the Test environment so no issue on time.

  Any help would be appreciated.

  Concerning

  Hello

  The minimum version required to upgrade to 12 c is 11.2.0.2.0

  The version of your database is 11.2.0.1, so first you must upgrade to 11.2.0.2 or later and then update can be performed.

  This requirement applies to the backup rman as well.

  We do not have this restriction with datapump

• can I use "Oracle Database 12 c: performance management and Tuning" training for the certification "Oracle Database 11g: Performance Tuning 1Z0-054 '"»

  I took "Oracle Database 12 c: new performance management and Tuning" the oracle University training. Now I would like to get certified on "Oracle Database 11g: Performance Tuning 1Z0-054 ' exam. Is this possible?

  I guess you ask if you can use the course 12 c as long as the condition of course for the review of 11g.  Over 12 c is not listed as one of the options for the 11 g certification and course requirements are normally specific version - at least with DBA certifications.  If you are already an Oracle OCP DBA, of course, there is no requirement of course for the review of performance tuning.  From what I know the training requirements for other certifications, I do not that you will be able to use it. However, Brandye will provide a definitive answer to whether the course 12 c would be acceptable for 11g certification.

  That said, I'm with John - 12 c review is about a community of 85 to 90% in the review of the 11g and is currently about 20% of the price while it is in beta.  What is the point of trying to cross the releases?

• Link to database not be created using a stored procedure

  Hello

  I am creating a link of database using a stored procedure.

  Here is the code for it

  CREATE OR REPLACE PROCEDURE create_db_link (ca_db_name IN VARCHAR2,

  ca_service_name IN VARCHAR2)

  AUTHID CURRENT_USER IS

  BEGIN

  EXECUTE IMMEDIATE ' create public database link test_db_link connect to ca_db_name identified by ca_db_name using "ca_service_name" ';

  END create_db_link;

  During execution of the code is created the db_link. But, when I ask all_db_links I get the following result.

  PUBLIC

  TEST_DB_LINK. WORLD

  CA_DB_NAME

  ca_service_name

  20 Aug 13

  Could you please help me understand why it shows the parameter names in the name column of the USER and the HOST instead of the name of the database and the name of the service?

  This is to show exactly what you said to do.

  Did you expect that Oracle would read as if by magic through your string you passed to run immediately and magically know to replace all occurrences of the string that correspond to local (or even global) parameter/variable names with the values of these variables?  It does not work like that.  You could concatenate the values into the string.

  for example

  EXECUTE IMMEDIATE ' create public database link test_db_link connect to ' | ca_db_name |' identified by ' | ca_db_name: ' using the "' | ca_service_name | " ' ;

  But why are create you database links running?  Shouldn't this be part of the design of your application and the initial fact before the application runs?
