• Urgent: db link from oracle 10g to sql server 2000

  Hello

  I have an oracle 10g db connection to sql server 2000. It was created a couple of years. This works.

  I have now created another link db of the same oracle on the same sql server server but it does not work.

  But I'm getting ORA-28500 and error IM002

  . Please notify.

  I can't understand what is wrong as I followed the hs odbc set up on this link db in the same way as I did 2 years ago.

  Thank you

  Just sort the problem.

  Basically, I use HSODBC to connect to SQL Server from Oracle (on windows 2003 64-bit).

  To do this, I need to create a connection ODBC from Oracle to SQL Server.

  HSODBC is a 32-bit application and is why we use the ODBC 32-bit driver when we create the ODBC connection.

  When I created the connection ODBC from Oracle to SQL Server, I used the ODBC 64-bit driver and that's why the system could not find the name of the data source.

  I have now created connection ODBC from Oracle to SQL Server via the ODBC 32-bit driver and everything works fine now.

  No offense to anyone, but as you all works using Oracle software, I was hoping a better answer than some of the answers above. You can say that you did not understand the question or you do not know the reason why it happened.

  I have just listed how the problem was fixed so that in the future one having the same problem can benefit.

• Oracle 11.1-> SQL Server Express

  Hello

  I have an Oracle RAC 11.1, 2 nodes running under Linux Red Hat.

  This database needs to connect to a SQL Server Express Edition 2012 to query a simple table with standard fields (varchar, number, date).

  For security reasons, we want that the Oracle database initiates the connection.

  Reading the documentation and various posts on this forum, I understand that I must install the database for (free) ODBC bridge or a bridge of database for MS SQL Server (need a license!).

  I would choose the free one, but I'm just a little surprised that I have to install a huge soft (~ 550 MB) just to query a table.

  • First of all, someone confirm that it is the only solution to interrogate a heterogeneous database to Oracle?
  • Second, what is the maintenance effort for the gateway database? Is there a backup instance, or something else?
  • Finally, if I have to use, can I install Database Gateway 11.2 (or 12?) and connect my 11.1 RAC with any problem?

  Sometimes I wonder if I had instead to make an interface with the .csv files...

  Thank you for your help.

  Kind regards

  Yann

  Yann,

  automatically when you install the Oracle database software you will get Dg4ODBC installed (on platforms where it is available). For you 11.1 installation DG4ODBC running on Linux, it is installed by default - you can check your Oracle_home is a HS/admin directory, you have the compiled executable dg4odbc (you'll find it in $ORACLE_HOME/bin directory) or whn using $ORACLE_HOME/OPatch/opatch lsinventory-detail.

  When you do not want to install anything on your production Oracle server, then you can either install the gateway on the MS SQL Server machine and use the MS SQL Server ODBC driver delivered with your SQL Server installation, or you can also install it on any computer, where you find a driver suitable for SQL Server ODBC.

  Thus, for example, that you can also use another Linux machine, install the driver ODBC for MS SQL Server on this machine, then on the bridge. Now, you can connect with your database of Oracle running on the Linux cluster to connect to the gateway on the other Linux machine. Then the gateway that will load the ODBC driver and connect to SQL Server.

  The only restriction is that you must have a driver ODBC for MS SQl Server on the computer where you install DG4ODBC.

• Oracle on the SQL Server tables dblinked query error ORA-00904

  Hello
  
  I created a dblink to a SQL from Oracle database using generic connectivity.
  The following query returns the error ORA-00904 invalid identifier in the (tblEmp.Empno) WHERE clause
  
  SELECT 'EmpNo', "EmpName", "DeptName".
  OF tblEmp@sqlserver.
  tblDept@sqlserver
  WHERE tblDept.DeptNo = tblEmp.Empno
  
  I had to include the column names between double quotes because of the case review of the columns, but I can't do the
  same thing for the WHERE clause.
  
  (1) so how can I fix this error?
  (2) also how can I include the Deptno column with the table alias in the columns list?
  (Deptno is ambiguous in the Emp and Dept tables)
  
  Kind regards
  Sam

  Looks like you have case-sensitive column names, try this

  SELECT "EmpNo","EmpName", "DeptName"
  FROM tblEmp@sqlserver e,
  tblDept@sqlserver d
  WHERE d."DeptNo" = e."Empno" --<--- are you sure this is the correct join condition
  

  What should we not

  WHERE d."DeptNo" = e."DeptNo"

  Details of base for sync history is MOBILEASDMIN. C$ SYNC_HISTORY. This will give you the id of the customer (name), start and end times, success or failure (and error if failure) as well as the total volume of data uploaded and downloaded.

  You can get more details by joining with c$ sync_his_pub_items on session_id, and this gives details of each downloaded table (phase = UPLOAD) regarding the timings and records and the same for the download. Upload tends to be the complete set of tables (records = 0 for no activity), while the download is only active tables and includes a full refresh occurred

  You can get information for the MGP process via mgp_history c$ and c$ mgp_his_clients

  As all the repository data is stored in the database, there are a lot of possibly interesting things if you look through it.

  We use SQL and PL/SQL to make reports on different users with clocks in a loading time and identification of customers having problems

• Dblink Oracle to sql server, multiple database on the same server sql under a dblink

  Hi, we managed to set up an Oracle dblink to sql server and retrieve data.

  The user of sql server have been using via dblink has access to multiple databases on the same sql server

  But the question is how in oracle (if possible) prepend you the SQL access to this?

  For example:

  Sqlserver_prod has the user sqlserver_user which seems to be set up as default database sqlserver_db1

  But we have select access to sqlserver_db2

  all work well as sqlserver_user

  Select * from table_fromdb1

  Select * from dbo.table_fromdb1

  Select * from sqlserver_db1.dbo.table_fromdb1

  as does

  Select * from sqlserver_db2.dbo.table_fromdb2

  more in Oracle

  Oracle_db a dblink sqlserver_prod. World connection sqlserver_user

  everything works fine

  Select * from 'table_fromdb1"@sqlserver_prod '.

  Select * from 'dbo '. "table_fromdb1"@sqlserver_prod

  But how to (if possible) access from oracle

  sqlserver_db2.dbo.table_fromdb2

  without having to create a new sqlserver_db2_user referenced in a new dblink

  If oracle for oracle would be

  Select * from remote_oracle_schema.table@remote_oracle_db

  Hello

  You cannot select a table in a different SQL * database server from that to which the gateway instance connects.
  As stated in the documentation-

  Oracle® database gateway

  Installation and Configuration Guide

  11g Release 2 (11.2) for AIX 5 L Based Systems (64-bit), HP - UX

  Itanium, Solaris (SPARC 64-Bit), Linux x 86 operating system,

  In the section.

  The example SQL Server multiple databases: Configuration of the modem router

  A separate instance of the gateway that is required for each SQL Server database. Each

  instance needs its own Gateway system ID (SID).

  You will need to create a new instance of the gateway for the SQL * Server DB2 as well as a link separate db.

  Sam,
  The link between DG4ODBC and SQL * Server is managed by the information and the driver specified in the system DSN defined as parameter HS_FDS_CONNECT_INFO.
  When you create the database link, you should double quotes around the user and the password under SQL * Server is case-sensitive. If quotes are not used, they are translated to uppercase, so try-

  create database GSIS_PQSR link
  connect to 'User_name' identified by 'PASSWORD' using 'GSIS ';

  in the correct case as defined on SQL * Server.

  For the ora-2019 check that-

  -initGSIS.ora is located in the C:\Oracle\app\amk1cob\product\11.2.0\dbhome_1\hs\admin directory
  -that the tnsnames.ora entry is located in the directory $ORACLE_HOME\network\admin for the RDBMS not the C:\Oracle\app\amk1cob\product\11.2.0\dbhome_1\network\admin of the entry door.

  There are 2 bridge - commercial database gateway for Ms SQl Server, which requires a license and database for ODBC gateway which is free. The license for DG4ODBC is included in your license data. You just need to install an ODBC driver on your Linux machine (for example, to use the MS SQl Server for Linux ODBC driver - details can be found here: http://www.microsoft.com/en-gb/download/details.aspx?id=36437 ). and then configure the gateway using the My Oracle Support Note:

• Oracle and SQL server database

  Hello

  Thank you

  What do you mean by "an external tool such as SQL Sever"?
  SQL Server is Microsoft's RDBMS product.

  Oracle data files are in a binary format that is known only to Oracle. (Like SQL Server data files are in a binary format known only to Microsoft). Unless you're talking about a binary dump, they can be "seen" by the published interface that is used by all clients. In the case of Oracle, these customers would include sqlplus and a multitude of third-party products, as well as programming languages that can make calls to the oracle SQL Developer interface. And in all cases, he will eventually return to pass SQL statements.

  What is your goal?

• Data migration from Oracle to SQL Server

  Hello
  
  I have the Oracle database in one or several table, I also blob data, i.e. images are stored, now I want to move that data to the sql server database, which is the best way to do this?
  
  I would like to test for a migration of the table that contains the image data in the Oracle database and invade the SQL Server table.
  
  How to test for an Oracle table data to SQL Server migration?
  
  But the first thing I want to confirm is that if the Image from Oracle DB to SQL Server DB data are possible? is there something must be supported during the migration?

  I think that it is supported. The equivalent data type in sql server is IMAGE/varbinary (max)

• Migration from SQL Server to Oracle database

  I have 2 questions:
  
  1. we intend to convert our sql server databases oracle OLTP databases. I tried to use SQL Developer to migrate a database of small sql server to oracle (size 5 GB) database. It was fine. When I tried to migrate to a different database (size 90G), it takes too much time. The problem with sql developer is I can not pick and choose tables. 250 paintings, I need to migrate tables abt 80 (the size will be abt 50 G). What is everyone can share their experiences, as appropriate, converting databases of size average sql server for oracle databases? other options?
  
  2. I intend to convert the sql server ddl to oracle ddl. I have tested bcp out and use sql loader to import the data. Right now I am manually creating the oracle tables sql server tables. I use http://download.oracle.com/docs/cd/E11882_01/gateways.112/e12069/apa.htm#BABCIIDI to convert the code. Are there other ways better to convert sql DDL DDL Oracle Server?
  
  Thanks in advance

  DDLS must be converted manually. Oracle is not SQL-Server.

  If for example, you have the option of partitioning, you should consider using the partitioning index and when it is possible. Not all tables must be hash tables. Do postpone you creation of segment or not? What type of tablespace? Set yourself free percentages and allows you to manage when the data block is on the free list and how much is reserved in the block of data to update rows in this block?

  There are many considerations to be taken with regard to the physical database design.

  Using BCP and SQL * Loader sound good. SQL * Loader is fast and scalable - use it to load up to 3.6 million lines every 60 seconds. Direct and parallel charges will give the best performance in this regard (assuming that the underlying table structure and use supports this approach).
