Using Mimer SQL with iODBC on Mac OS X
Tools and Interfaces
As an example of connecting to a Mimer SQL database server using ODBC we will use the iODBC product, an ODBC Driver Manager. To verify the connection setup we are going to use a demonstration program delivered with iODBC called odbctest.
In this article the Mac OS X platform, where iODBC is installed by default, is used.
Install Mimer SQL
First, install Mimer SQL for Mac OS X. The software will by default end up in the
/Applications directory with subdirectories like
examples under a main directory. Links to achieve a proper behavior of executables, man pages and library lookup will be made to system locations such as
You can find Mimer SQL Engine for Mac OS X on the Mimer SQL Download Page.
Create a Mimer SQL Database
As said before, Mimer SQL is by default installed under
/Applications. To create a database, use the Finder application to start the Mimer SQL Database Install application found in the main directory of the Mimer SQL installation, e.g.
When this application opens up, you should decide a name of your database and a password for the Mimer SQL database ident called SYSADM. This is the database user that is referred to as the System Administrator for any Mimer SQL database.
For now, you can use the default values for all other options available in the screen.
As you can see in the lower section of the screen, the option Add To ODBC Environment Setup is checked by default. This means that an ODBC Data Source definition, a System DSN, is created in the ODBC environment automatically when the Mimer SQL database server is installed. The DSN will be given the same name as the one you have chosen for the database.
Click the Create button to start the operation.
The ODBC Environment
If you want to list your ODBC definitions, make additional ones or if adjustments are needed, an ODBC Administrator is available. In the
/Applications/utilities folder you find the ODBC Administrator application. Click on the icon to start the administrator.
If a Mimer SQL Database Server was installed properly you should have a Driver definition for Mimer ODBC. Click the Drivers button:
You should also have a data source defined. Click the System DSN button to get to the Data Source list:
If you want to add a Mimer ODBC Data Source manually, click the Add button in the screen shown above. Select a Mimer ODBC driver in the Drivers list and press OK. You will now get a dialog where you should give a name and description for your data source. Do that and then press the Add button in the same window. Enter the Keyword "Database" by a double-click on "Key", press the tab key and enter the name of your Mimer SQL database as Value. Please note that you must unlock the ODBC Administrator, by using the locker icon in left down corner, to be able to do any modifications.
Verify your ODBC setup
When Mimer SQL is installed properly and a Mimer SQL database server is installed and registered in the ODBC environment, open up a Terminal application window so that you get a system prompter. The Terminal application is found in
/Applications/utilities. Start the
odbctest program (or iodbctest and iodbctestw, for wide characters, in later versions), the iODBC Demonstration program, and use the database name for the database that you created earlier. In the following sample session the mimserver database name and the SYSADM user (with the password chosen when the database was created) are used:

Have a nice day.
Note! The error message "Dialog failed" will be received if the ODBC connect string is not given in the format "DSN=mimdb".
The Mimer ODBC Driver and the DSN is automatically installed in system wide locations, i.e
/Library/ODBC. In some situations it may be necessary to define the ODBCINI environment variable to get access to these definitions:
# export ODBCINI=/Library/ODBC/odbc.ini
