Overriding the system-default session parameters

The database server obtains values for the session parameters from the parameter-information descriptor. The database server initializes the parameter-information descriptor with the system-default session parameters in the following table. To override these system-default values, you can initialize your own parameter-information descriptor to set session parameters.

The following DataBlade API functions access default session parameters for a client LIBMI application.

mi_set_parameter_info(): Sets session parameters for the current session
mi_get_parameter_info(): Obtains session parameters for the current session

To override the system-default session parameters:

Allocate a parameter-information descriptor.
Fill the fields of the parameter-information descriptor with the default session parameters you need.
If you do not set a particular field, the database server uses the system-default value in Table 1 for the associated session parameter.
Pass a pointer to this parameter-information descriptor to the mi_set_parameter_info() function.

You can examine existing session parameters with the mi_get_parameter_info() function. This function populates a user-defined parameter-information descriptor with the current session parameters.
