If an operation does not finish within the specified time, it is automatically cancelled. Specifies a file DSN rather than a registry entry. Having established the connection, the client driver maintains communications with the database server. For detailed information, see the Microsoft support site search on “file DSN”. In most cases, this information is stored within a DSN, which has a logical name for use within the client application.

The details needed depend upon the database technology. The InterSystems sample is called cacheodbc. This allows some Microsoft applications to allocate the properly sized buffers to hold multibyte data.
If you are using an ODBC application that does not allow you to set the timeout value and the timeout value is too small, you can use the Disable Query Timeout option to dobc timeouts. Specifies a file DSN rather than a registry entry. This log is for troubleshooting; you should not turn logging on during normal operation as it will dramatically slow down ODBC performance.
Caché ODBC Driver FAQ
A client application is linked to an ODBC driver manager, which accepts the calls. The ODBC initialization file is used as follows:.
The fields are listed below and are required unless otherwise specified:. For example, this may include the server on which the database resides and the port to use when connecting to it. Select the appropriate one to create DSNs for bit or intersydtems drivers. In the example above, the last three lines specify the SSL connection. This should be the name of the service principal that represents InterSystems.
This file includes odbx following variables:. Login credentials to access the database, if the database is protected by a password.

Information on locating and accessing the database. Having established the connection, the client driver maintains communications with the database server. For this option, also specify the following settings:. The default for InterSystems is If an operation does not finish within the specified time, it is automatically cancelled.

A popup window will display information on ping success or failure. It can be on the same or a different machine than the client driver from which it is receiving calls. When defined, this variable specifies a path and file, such as:. To register the driver, specify flags -i cachd -f and your odbcinst.
This is meant merely as an example. 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. Specifies the username to be used by the Intersystfms connection.
This example defines the following values:. Name and Location of the Initialization File. The directory also contains a readme. The following options are available:.
Some ODBC applications, however, hard-code this value. To add a local DSN, specify flags -i -s -h -f and your ccache. The values must be defined as follows:.
