start the cube of Alphablox

[j***@gmail.com]

I want to design a program that start the cube of Alphablox,
the code is

public void StartCube(String cubeName){
Cube cube = null;
try
{
AdminBlox adminBlox = new AdminBlox();
cube = adminBlox.getCube(cubeName);
try
{
if(!cube.isStarted()){
cube.start();
}
}
catch(ServerBloxException sbe)
{
sbe.printStackTrace();
}
}catch(ServerBloxNotFoundException sbnfe)
{
sbnfe.printStackTrace();
}
}
the cubeName is "COST_CV",and the Cube works fine.
When I have stopped the "COST_CV" Cube,then the App runs error!
the error Message is
"B2 Alphablox has stopped?{1, date,MM/dd/yy kk:mm:ss}? ( DB2 Alphablox has stopped?{1, date,MM/dd/yy kk:mm:ss}? )

What can I do?

How did you stop the cube? Manually in your browser using the Alphablox administration pages, or programmatically? Can you provide the Alphablox Server.log file for this scenario?
