Live cache start and stop

Hi Guys,

I have some problem in live cache in APO , i was posting in APO forum could not able to find clear findings

so i am diverting my questions here in this forum

basically the APO and R/3 system are running smoothly with no problem in CIF

but accidently we done the below steps

Entered into transaction LC-10

Click Live cache Monitoring

click the folder - Administration

click Operating under - configuration

There are two Icon bar - start LiveCache and stop LiveCache

First i clicked stop and then after few minutes i click start

After some time i try to open the Product view in APO, the system says Live cache not available

can some one help me in this regard

Thanks

Raj
