• Using Oracle ODBC connection to a remote Oracle database gateway

  Oracle 11 g 2

  RHEL 6.4

  Someone at - it use the Oracle ODBC gateway to connect to a different Oracle database?  Problems with this configuration?  Where can I get the drivers for Linux ODBC?

  (I know, "why not use a dblink?" -Well that would be against the strategies of enterprise security)

  Thanks for your reply.  What I wanted was 'just' a dblink of 1 db Oracle to another Oracle db w/o the use of the ODBC bridge.

• Unable to connect to remote oracle database!  Help, please!

  Hi all-
  
  I am a new user Oracle and you are allowed to access a remote Oracle database, however I have problems with the installation/configuration program! I downloaded the driver Oracle and the Instant Client (11.2.0.2.0) because I need to use Microsoft Access for the data access (the Access database is already configured to the correct Oracle database). I'm under the impression that, to do this, I need to be able to use the ODBC Administrator to get all set up. Note: Im working on Windows XP.
  
  I have questions:
  
  -I don't seem to have installed Netca (which seems to be the recommended method to configure a connection). I have manually adjusted the TNSNAMES file. ORA file so it matches the database, but I'm not sure what would be my next step.
  
  -When I open SqlPlus it wants a username and password, and I tried the default settings and got an error each time. I must first use SqlPlus, or establish a connection via ODBC first?
  
  -Also: ODBC requires a TNS Service name, and I'm not sure, where this is established; something that would give the database manager?
  
  I really just do not know how to configure this remote connection! I continue to run with obstacles and really want a reference "step by step" on the way to do it, if there is such a thing. Any help or additional reference material would be appreciated! I ran by the content of the forum, but have not been able to decode the jargon! Thank you very much in advance.

  Hi Ed-

  I use the Oracle's ODBC driver. I think there may be a problem with the TNSnames file because I tried to add this file as a"Data Source", and he also said that a connection could not be established. What do you mean by the MS implemented? A configuration of Data Source?

  By MS implemented, I was referring to the MS ODBC for Oracle driver, against the Oracle ODBC for Oracle driver.

  The "source of data file' has nothing to do with the tnsnames file. The ODBC Manager retains its DSN definitions in one of three places. "User DSN" is stored in the HKEY_LOCAL_USER registry, the "System DSN" definitions are stored in the HKEY_LOCAL_MACHINE registry and 'FILE DSN"definitions is stored in a file... I don't remember exactly where or what it's name is as I have (when he is forced to deal with odbc) just keep things simple and use "system dsn". But these aren't all the definitions of ODBC, Oracle tnsnames file.

  The link between the ODBC DSN and the tnsnames.ora presents itself as a property of the ODBC definition. Suppose you have this for a tnsnames.ora entry:

  houston =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = vmlnx01)(PORT = 1521))
      )
      (CONNECT_DATA =
        (SERVICE_NAME = orcl)
      )
    )
  

  Then
  -When you set up your odbc dsn, if you use the MS for Oracle driver, you must specify 'houston' as the 'server '.
  -When you set up your odbc dsn, if you use the Oracle odbc driver, you must specify "houston" as "the TNS Service name".

  Im going to try to post a modified version of the content of my TNSnames.ora file (for some reason any the "content is not allowed ' by the forum), but I would like to get some comments on whether the structure of the content may be the problem.

• Remote Oracle database import table

  We want to create a local copy of a remote Oracle database table, because we will use this table at about 14 locations to update other local tables. The table contains about 1 million records and does not change frequently. We can say that a row has changed in a month, but that's just guessing there is no guarantee.

  The contract synchronization process he uses begins everyday. He gets the new copy of this table, update other tables based on this table and then clean the intermediate table. I want to know how can I copy data this staging table in my local machine. I have following options:

  (1) using the Materialized view, do a full refresh every day before the process starts every day. (we cannot use fash refresh because we cannot change anything on the remote oracle database)

  2) Insert like the select statement, but what happens if the user started two processes at the same time by mistake.

  (3) just join with the remote table in each query, instead of making the local copy.

  (4) use the temporary table and insert as the select statement.

  CORE 10.2.0.4.0 Production

  AMT for Linux: release 10.2.0.4.0 - Production

  NLSRTL Version 10.2.0.4.0 - Production

  I suggest also using a synchronization logic to only transfer new data in the remote table.

  If data it does not change often (as you mentioned) then you can copy the table overall once, and after that the transfer only changed using some sort of regular job data.

  This will not work if you have a mechanism to understand when a record has been changed in the table.

  For example, if you have a timestamp column, which is always filled to insert and update you will be able to extract only the difference.

  You will have a brief fight with deleted records but still doable

• PC to tv connection error "no signal - check the connections and the external device is turned."

  Original title: pc to tv connection

A message appears on the screen saying "no signal - check the connections and the external device is turned on."
  I had posted before saying that I had problems ranging from VGA to VGA. That's why I bought the DVI adapter to try another solution.
  I hope I made things clear enough for someone to help him.

  Hello

  Oracle EM is the best to identify the use of the processor and memory used by each session.

  In addition, use after query to calculate the memory used by each session of the.

• sqlplus to connect to remote oracle database server

  Hello
  
  I have the server database oracle 10g on solaris 10 and I usually connect using my account to solaris and run sqlplus on the server itself. This works!
  
  I downloaded and installed the client instant oracle for solaris 64 and I can launch sqlplus command but I'm confused on what should be the syntax of the command to connect to remote oracle and solaris 10 database server where I have the system account.
  
  I tried sqlplus help but still I could not correct syntax that may be used to authenticate to the oracle server.
  
  I tried
  
  sqlplus user@hostname:1512/SID
  
  then he asked for password, but when I typed the password and you press on enter, it gave some error
  
  but he still asked as username so I type user@SID and then prompt password - typed password and it works!
  
  so I do not understand what should be the correct syntax for that in the first attempt, I'm able to connect.
  
  If possible, please give the exact command with realworld examples, (I tried with sqlplus - help already)
  
  Thanks in advance.

  wonder what if I didn't tnsnames.ora on the client machine, how will be the syntax?

  You generally need (or at least strongly want) a file tnsnames.ora on the client machine.

  -You could configure Oracle Internet Directory and allow this product provide TNS alias resolution for the Organization (similar to the DNS configuration for a LAN).
  -Many tools (I have not personally tried SQL * more and it can be dependent on version) allow you to specify the whole TNS alias in the tnsnames.ora file (i.e. everything that follows the abcd.domain.com = entry) but which is extremely heavy for type
  -According to the version of the Oracle file sqlnet.ora, the complexity of your configuration client (that is, if you try to use the more advanced features such as failover), you may be able to use the syntax EZConnect

  sqlplus username/password@host:port:SID/service_name
  

  Where host is the server that the database is running, the port is the port the listener (i.e. 1521 default) listening and SID/service_name is the SID or service name, you are trying to connect to.

• With the help of OBIEE with Oracle Database Express Edition? SOLVED

  I have a customer who wants a quick demo of OBIEE. They sent us as data source csv files. I migrated the Excel files for ease of use, but Excel files seem to have limitations on how I can combine columns, such as the concatenation and formatting.
  
  I then loaded them in a database Oracle Express Edition, assuming that more "database" functionality would be placed at my disposal. I managed to load in the Administration tool, but the answers gives me the following error when I try to view the results of the Express database:

• Configuration of the DBUM connector for an Oracle database more

  Hi, I only configure DBUM connector for Provisioning users for an oracle database. I need the provision to users of other databases on the test and production environment... I use OIM11.1.2.2 and DB version 11 GR 2.

  I duplicate the work using an existing task that is used for the existing work. Create n number of jobs and to provide different it resource for each work and the calendar (see: https://community.oracle.com/message/10594440).
