  Hello
  You can use the database for ODBC (DG4ODBC) gateway to establish a connection to the MySQL database, and then use the copy, "create table as select... "or select / insert commands to move the data from MySQL in Oracle tables.
  You will need access to My Oracle Support, but the following notes have details on setting up Dg4ODBC on variosu - platforms

• Connection to the database to Oracle using Oracle Apex 5.0.1

  Hi all

  Is it possible to connect to the Oracle (Oracle SQL Developer 4.1.1) database using Oracle Apex 5.0.1 instead of using the object browser. As he was more workspace after you have downloaded the data we have on CSV Excel.

  For example: regardless of the tables I've created in the Application Builder is created in the object browser. We have limited the workspace of 500 MB. This is the reason why we cannot use this method to load the data and retrieve it. (Note: can I ask 2 GB of space to work on the approval of the Director, who is still not sufficient)

  Is it possible that I will create an apex.oracle.com application by using the application builder and I will create in the database tables. When I load the file in application, data will be stored in the database Oracle instead of the object browser.

  Well let me know is possible, if yes, how can I proceed.

  If this isn't the case, please let me know how I can get more workspace.

  According to my understanding, other possibilities are: 1) taking backup of old files and free up space, 2) create another workspace and get extra work space.

  Thanks for your help!

  Kind regards

  Hello

  When you load data using APEX SQL Workshop utilities for example, the data is stored in your database tables.

  Object browser is just seen tool your schema as the table objects and the data in the tables, just as SQL Developer.

  If you have no good reason to keep these files that you downloaded in the workspace, delete those. Data is stored in database tables.

• Check the connection to a remote Oracle database

  
  Hello

  I have an application that runs on a server that connects to an Oracle database on another server.  The application uses Java and JNDI to connect, there is no Oracle client installed on the server hosting the application.  The application seems to have been to connect to the database on the other server.  How can I check that the connection to the database still work from the server hosting the application?  Is there a software tool that I use does not require Oracle client must be installed.

• 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?

• Developer unable to connect SQL database Oracle as a SYSDBA

  Hi all
  Recently, I installed SQL Developer3.0 on my machine and try to create the connection to the local Oracle server. But something confuses me. When I login as normal role, it can connect DB successfully; When I connect as sysdba role named sys, it has always failed and show "name of user and password invalid. I don't know that the username and password are right, because I haved connected the oracle DB from pl/SQL with the same user name and password. And I also chose the role as sysdba. SQL Developer3.0 not support connect as sysdba? I would be very grateful if someone could give me a helping hand. Thanks in advance.

  Hi 851634,

  Do you need a password for remote sysdba (old link) file?
  Cannot connect as sysdba in Oracle Enterprise Management Console

  You can try to open a session (loopback) on the network as sysdba, which requires a password file.

  Hey Vinny,

  No, the host tnsnames.ora must not refer to the place where the SQL * Server database is active.  The tnsnames.ora entries is intended to guide the user who calls the database link by using this entry to a listener running on the computer and the port in the entry. The listener then directs the user to everything that is referenced by the SID in the listener. If it is an Oracle database, then you are linked to the database. If this is an entry of gateway referenced by having the (HS = OK) then you are linked to the gateway which then liaises with what non-Oracle database is accessible through the gateway of the option.  You cannot directly connect to the non-Oracle database by using the IP address of machine non-Oracle in tnsnames.ora. You need to go through the door entry referenced by the listener to establish the connection.

  For the listener, you can set the path to the ORACLE_HOME of the gateway or RDBMS. However, the best option is to give the listener a different name from the default, so for the gateway, you might have-

  SID_LIST_LISTENER_GTW =

  (SID_LIST =

  (SID_DESC =

  (SID_NAME = GS2PIASQL03)

  (ORACLE_HOME=S:\app\oracle\product\11.2.0\tg_1)

  (PROGRAM = dg4odbc)

  )

  )

  LISTENER_GTW =

  (DESCRIPTION_LIST =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SLPIAM29)(PORT = 1525))

  (ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1525))

  )

  )

  You can then use-

  stop LISTENER_GTW

  Start LISTENER_GTW

  You cannot connect to a PDB file through a registration of the listener static like this, because there is just no SID not named MYPDB1. You must register the services dynamically. In the root.

  ALTER system set local_listener = "adc40:1550";

  editing the system registry;

• Copy of database SQL Developer - you can copy a database non-Oracle?

  
  I was hoping to use the database copy utility in Oracle SQL Developer 4.0.2.15 to copy data from a sybase database table in an oracle database table. I created both the Sybase and Oracle database connections, however only the Oracle connection is available in the 'Source' and 'Destination connection' lists drop-down in the copy database wizard. Is it possible to use this utility to copy a non-Oracle database, any advice would be much appreciated.

  Assuming that you don't have just to copy a single table (or just a handful of tables), 'copy Oracle"function should appear when you right click on your target table from the Tables node on the sybase connection.

  If you need to migrate tables more this can become tedious, but in this case probably consider using specially designed SQLDeveloper migration functions to migrate all drawings of third to Oracle databases (for this right click on the connection to sybase and choose "Migrate to Oracle").

• create the database with Oracle Client link

  Hello together,

  on my machine Windows 7 with Oracle Client installed 12.0.1.0, I'm trying to create a database link to a database server, which runs on Oracle Standard Edition1 11.2.0.2.

  When I connect to sqlplus on the client with "sqlplus/nolog" and type the command:

  SQL > create SID of the database link

  connect to the user identified by passwd

  using "tnsnames.ora connection."

  I have a SP2-0640: not connected. OK, it is clear, because I use sqlplus with option/nolog. But client-side normally I have no database, where I can connect. So I think, there is no user, or?

  The database to which I want to connect is located in tnsnames.ora.

  Generally: Is it possible to use the Oracle Client to create a database link? Maybe there's another way to do this?

  A big thank you and best regards,

  David

  You don't seem to understand the concept of a database link.

  A database link connects two databases. Not a client and a database.

  You need to link up in a data source to a target database.

  The only thing you need is a client of sqlplus in sqlplus client, you need to connect to the source database.

  If you can't connect to the source database, you must present the statement to someone.

• Problem when creating new connection of database with SQL Developer

  Hi all
  
  I am a beginner and I want to learn Oracle add up to my learning
  I installed SQL Developer on Linux Mint 12 (lisa).
  The installation went well, but when I try to create a new database connection in SQL developer, I get the following error:
  
  * Status: Failed - Test has failed: IO error. The network adapter could not establish the connection.* *.
  
  Could someone please suggest where exactly, I'm missing?
  
  Greetings - Vishal

  Have you installed the oracle database software locally? Have you created a database called "oracle?

  Developer SQL does not include a data base. For learning purposes, I recommend that you download Oracle Express Edition.

• Imported a few diagrams of Oracle database 11g oracle 10g

  Hello
  
  I have the task to import some schemas are basis of oracle 10g (10.2.0.4) in the database to oracle 11 GR 2 (11.2.0.2). Now I only oracle 10g export and import utility (the 11g server is not where I give myself the import duties).
  
  I can do the export of the g 10 patterns using the 10 g utility to export and then import into database 11 g using the 10 g import utility? I ran a test to do this and found it works but I would like also to have advice from experts on this subject.
  
  Also another question is: If the schema of the source is 11g - assume - can the utility of export/import of 10g still work in this case? I mean the scheme for the export of db1 say (which is 11 g) using 10 g utility to export and import them into 11 g db2 database (which is still 11 g) using 10 g import? I request because I don't have access to the 11g server and trying to find what I can do with the 10g utilities.
  
  Thank you

  set up a database connection to the database to version 10 gr 2 in 11 GR 2 database.
  Now using the client impdp GR 11, 2 utility use
  Impdp network_link =

  Fact.
  Your "objection" you have no access to GR 2 11 does not count that you can install a client of 11 GR 2.

  Also in general do not use a version more low imp to imp to a higher version database
  Exp and imp are also deprecated in 10g and more.
