Question about b20 vtec?

I currently have this setup in my 92 civic hb. The car has been sitting, undriven for about eight months. When I went to start up the vehicle I found that the alternator is not giving power to the quickly dying battery. However, I also was bit worried by the amount of white smoke that comes from the greddy exhaust muffler. What should I do to make this smoke dissapear. I mean I have had many suggestions to let the car run for about thirty minutes and it may dissapear? I have bee told to buy a product to stop the burning oil that can cause such a problem? I have also been told not to run the car at all? Please any suggestions regarding my current situation would be greatly appreciated. thanks for your help and time.

if the cars been sitting for 8 months. i would first change the oil, then let the car run for 30 minutes. the white smoke is probably condensation in the exhaust
