Today was interesting day. WebLogic server decided to not start applications properly after restart of linux server. In all application logs there were stuck threads. For some reason WebLogic 11g console did not respond and login was impossible. This is another shitty bug from Oracle mighty WebLogic application middleware. After killing all applications and server forcibly and starting again it worked properly. But what is the reason of this behaviour. Why this product of Oracle has so many bugs and it is still overpriced. In most cases diganostic of this well coded java container is out of scope, you simply can not identify problem. Google and Oracle documentation are not very useful. I wish good luck to everyone who use this “semi” professional tool.
