Detailed Description

Holds access parameters and the configuration of the lease and hosts database connection.

The database access strings use the same format as the strings passed to the isc::dhcp::LeaseMgrFactory::create function.

void isc::dhcp::CfgDbAccess::setAppendedParameters ( const std::string & appended_parameters )

inline

Sets parameters which will be appended to the database access strings.

Parameters

appended_parameters String holding collection of parameters in the following format: "parameter0=value0 parameter1=value1 ...".

void isc::dhcp::CfgDbAccess::setHostDbAccessString	(	const std::string &	host_db_access,
		bool	front = `false`
	)

inline

Sets host database access string.

Parameters

host_db_access	New host database access string.
front	Add at front if true, at back if false (default).

Definition at line 62 of file cfg_db_access.h.

void isc::dhcp::CfgDbAccess::setIPReservationsUnique ( const bool unique )

inline

Modifies the setting imposing whether the IP reservations are unique or can be non unique.

This flag can be set to false when the server is explicitly configured to allow multiple hosts to have the same IP reservation in a subnet. In that case, the createManagers function will attempt to use this setting for HostMgr.

Note that the HostMgr can reject the new setting if any of the host backends used does not support specifying multipe hosts with the same IP address in a subnet.

Parameters

unique new setting to be used by HostMgr.

void isc::dhcp::CfgDbAccess::setLeaseDbAccessString ( const std::string & lease_db_access )

inline

Sets lease database access string.

Parameters

lease_db_access New lease database access string.
