Default Option Management

Options can be handy for controlling the Data Virtuality Server behaviour, and the Data Virtuality Server has several stored procedures for handling default option values. On this page, we give information on these procedures; for detailed information on each option, please refer to this section.

SYSADMIN.setDefaultOptionValue

This procedure writes a default option:

SYSADMIN.setDefaultOptionValue( <optionname>, <optionvalue> )

Example

CALL SYSADMIN.setDefaultOptionValue( 'ALLOW_CARTESIAN', 'ALWAYS' )

SYSADMIN.getDefaultOptionValue

This option gets the value for the specified option:

SYSADMIN.getDefaultOptionValue( <optionname> )

Example

CALL SYSADMIN.getDefaultOptionValue( 'ALLOW_CARTESIAN' )

For both setDefaultOptionValue() and getDefaultOptionValue(), <optionname> should be passed without the dollar sign ($).

Setting a Default Option to its Default Value

A default option can be reset to its default value by providing an empty string as a value:

SYSADMIN.setDefaultOptionValue( <optionname>, '' )

Example

CALL SYSADMIN.setDefaultOptionValue( 'ALLOW_CARTESIAN', '' )
