Weblogic 12c and Managed Server in incompatible state

Oracle WebLogic application server (WLS) is quite a behemoth and usually works much better than e.g. OC4J which we previously had to use. But sometimes things don’t go as they should and it gets stuck. Some time ago my managed Server was in “FORCE_SHUTTING_DOWN” state and when trying to restart it I got an error message.… Continue reading

Using the WebLogic 12c Maven Plug-In for Deployment

Using the WebLogic 12c 12.1.2 Maven plug-In for deployment is much easier and quicker than going through the WebLogic Server’s AdminServer and Oracle Documentation provides good examples how to do it.

Connecting Jabra HALO2 Bluetooth Headset with Windows 7

Recently I got Jabra HALO2 Bluetooth headset for teleconferences but had problems to get it work with Windows 7 and Dell Latitude E6530.

Windows and X11 forwarding with Xming

Usually I prefer to do thing directly from the Linux terminal but sometimes there is a need for remote graphical tools and X11 forwarding. Linux supports X Forwarding with no extra software, on OS X you need e.g. XQuartz and on Windows you need two pieces of software: a secure shell program (ssh) to establish the remote connection and an X Server to handle the local display.… Continue reading
