Asterisk reload Problem for ODBC

Hi All,

I am trying to use asterisk for its real-time configuration for sippers.

While trying to to reload using the command
reload, I am getting the following error in the asterisk CLI.

[Dec 12 18:14:54] WARNING[3481]: config.c:2018 find_engine: Realtime mapping for ‘sippeers’ found to engine ‘odbc’, but the engine is not available

Can somebody help me to get rid of this problem.
