For detailed information, see the Microsoft support site search on “file DSN”. The driver manager also performs any necessary tasks so that the client application can communicate with the client driver and, ultimately, the database server. The details needed depend upon the database technology. Some ODBC applications, however, hard-code this value. This is meant merely as an example. Because it is an ODBC standard to allow the storing of usernames and passwords in clear text, the sample initialization file includes the username and password required to access the sample DSN.

In order for a process to initiate an SSL connection with these values:. To use a different odbc.
The directory also contains a readme. Name and Location of the Initialization File. The ODBC query timeout setting specifies how long a client should wait for a specific operation to finish.
cachee The allowed values are as follows:. If an operation does not finish within the specified time, it is automatically cancelled. Select the appropriate one to create DSNs for bit or bit drivers. This may be preferred in some cases because the vendor driver may take advantage of its knowledge of how the database works internally to optimize performance or enhance reliability.
Overview – Using Caché with ODBC – Caché & Ensemble
The ODBC initialization file is used as follows:. For an application to connect to a database via ODBC, the application must generally provide the following connection details:. In general, this flag should be off that is, set to 0 unless you have a specific reason for not using the ODBC Cursor Library. To add a System DSN, specify flags -i -s -l -f and your odbc. To register the driver, specify flags -i -d -f and your odbcinst.
This should be the name of the service principal that represents InterSystems. Having established the connection, the client driver maintains communications with the database server. It provides information so that the driver manager can locate and connect to an available DSN, including the path of the ODBC client driver required for that particular connection. Some ODBC applications, however, hard-code this value.
This value can have an affect when the ODBC connection is interoperating with an application that uses the decimal separator as defined for the current locale. Specifies a file DSN rather than a registry entry.
Information about the ODBC client driver to use. Select the appropriate version as follows:. For more information on Kerberos, see the Security Administration Guide. The following options are available:.
Defines all connection information directly in the connection string. The default for InterSystems is Using this information, the client driver connects to the specified database.
Caché ODBC Driver FAQ
Because it is an ODBC standard to allow the storing of usernames and passwords in clear text, the sample initialization file includes the username and password required to access the sample DSN.
For more complete information, including specific supported databases, see the online InterSystems Supported Platforms document for this release.
On Windows, it is a registry entry. For a particular vendor database, that vendor may offer its own version of the ODBC client driver for that platform. When selected, specifies the use of the current locale’s decimal separator; not checking this sets the decimal separator in the process to a period “.
If you are using an ODBC application that does cqche allow you to set the timeout value and the timeout value is too small, you can use the Disable Query Timeout option to disable timeouts.
It looks for the file in the following places, in this order:. It can be on the same or a different machine than the client driver from which it is receiving calls.
