Can Oracle 9.2 client connect to Oracle 12c server?
We have an old server which is an 11g version, and so far there's no problem connecting from client.
Thank You.
That isn't a supported combination, no. As it says in the documentation, you can see the supported client/server combinations at My Oracle Support note 207303.1.
The 9i client used to be supported with an 11g server, but is not with a 12c server. There is a specific note about it:
Attempting to connect from 9.2 to 12.1 will fail with an "ORA-28040: No matching authentication protocol" error.
We are currently using the 9i 32bit Client to connect to Oracle 12c 64bit server in test at the moment and so far it works but with caution.
For example, whenever you query certain data types not available in 9i but available in 12c, the system may crash. We therefore had to build views that convert the timestamp data type to the date data type for example. Then it works fine. Even use of indexes seem to work fine.

I am looking for a way to establish a database connection to a AS400 Release V4R3M0 via ODBC or even better with .NET. Under Windows XP I can access the AS400 with the ODBC interface and the driver from the IBM Client Access software. But my release is not working under Windows 10. I have downloaded the IBM Data Server Client Packages - Version 11.5. But I could not establish a connection with it.
I tried it with ODBC Datasource configuration and with the commandline
db2cli execsql -connstring "DATABASE=databasename;HOSTNAME=as400;PORT=8471;UID=user;PWD=password;"
Thank you for your help.
First, you'll need a rather old version of the IBM ODBC driver. Newer versions yield a password error when connecting to very old systems. I'm using the driver from iseriesaccess for linux 7.1.0-2. I guess the same applies to Windows.
Please realise that V4R3 is from 1998 and it will get increasingly hard to find ways to get functioning connections to it from modern Windows systems.
I'm fairly new to Oracle SQL developer. As I'm trying to make a new connection via TNS, I'm getting this error down below which I've been looking to solve for a while fruitlessly.
Error Message:
Statut : échec -Echec du test : no ocijdbc18 in java.library.path
Assuming MySQL is a typo (You are using port 1521, which is the default port for Oracle database, also its giving you ODBC error, so I assume its an Oracle database. Remember that you can connect SQL developer to a MySQL database, so please clarify if you want to connect to a MySQL database rather than Oracle) your problem is due to lack of Oracle Data Base Connector driver (ODBC). From this link download the latest version of Oracle Instant client and install it on your machine. Then define ORACLE_HOME to the path of Instant client installation (To the actual installation folder, the one that contains folders like bin, network and so on) and restart SQL Developer, then you should be good to go.
P.S. : as #thatjeffsmith has mentioned correctly in the comments, it's not necessary to have Oracle Client and/or ODBC (or similar) drivers in order to connect to an Oracle database. Using basic as the connection type and adding the correct connection info would suffice. This Article in Oracle Magazine has extensively talked about the different connection types.
I've asked this question on serverfault and someone told me to ask here.
Can I make a connection to a PostgreSQL server using FreeTDS, more specifically using the tsql command?
I've been trying for a few days now, using many different configurations. Even though I am able to connect to the DB using isql and PostgreSQL odbc driver, I can't make it work using tsql (it also doesn't seem to use odbc.ini or odbcinst.ini). So, I was wondering if the tsql command only works with SQL Server.
If you want, I can post the files freetds.conf, odbc.ini and odbcinst.ini.
Thanks.
FreeTDS only supports the TDS protocol (hence the name). And this protocol is only implemented by Microsoft SQL Server and the Sybase database.
So, no you can not use FreeTDS to connect to a Postgres database.
You need to use the Postgres ODBC driver, the Postgres .Net driver or the Postgres JDBC driver to do this - depending on the programming language of your application. From a C program you can also connect to Postgres directly using the libpq library.
Please suggest what is the difference between odbc connection and oracle server connection in crystal reports while connecting to oracle database.
Please suggest when we will use both of them
ODBC works with "rectangular" or 2D data. If you have spatial data, you will need to use the native Oracle client. Our DBA also says Oracle ODBC has to convert data types while a native client would be "apples to apples".
If you have a Crystal Server accessing an Oracle database, use the native Oracle client. On your workstation, also run the same client whether ODBC or Native as the server.
Has anyone connected Adempiere (ERP) (or any PostGreSQL db) to SQL Server 2012 Express?
There used to be an IT manager to help me out with this, but now i'm left alone with this.
I downloaded the free Sql Server 2012 Express and wanted to use the SSRS for Adempiere. It seems its running on the SQL Server 2010 for SSRS.
I have already added the ODBC Data Sources for 32 Bit. My computer is using 64bit, is there any incompatibility? I'm not sure if my server is 32 or 64bit.
I've tried following the instructions on http://postgresblog.blogspot.com/ but to no avail.
I already have Crystal Report running, so i'm sure its possible to run 3rd party software for Adempiere.
Anyone knows how i can use SSRS for Adempiere? Thanks!
Since you're using Express edition, if you're trying to connect to any Data Source other than an database on the same SQL Server instance it won't work.
See Features Supported by Reporting Services in SQL Server Express.
From that article:
Report data sources must be SQL Server relational databases that run
locally in SQL Server Express.
Also:
Analysis Services, Oracle, XML, SAP, SQL Server Integration Services
(SSIS), OLE DB, and ODBC data sources are not supported.
You're going to need a different edition to connect to an ODBC Data Source.
