Re: [Wrapper-user] Service started by Windows cluster does not work properly

[波波 . <gw...@ho...>]

Christian,

Thanks for your reply.

I rechecked the log, the problem is about my application, not the wrapper. My application creates a working thread after it started and tries to connect to the database. If it fails to do so, the working thread quits but the main thread keeps running. Then the service still runs but does not output anything. After I restart it, it connects to the database successfully and works correctly.
