The FMW Configuration Wizard Is Very Slow On Linux Virtual Environments. The Startup Of WLS Servers Is Also Very Slow. (Doc ID 1344974.1)

Last updated on MARCH 01, 2023

Applies to:

Oracle Fusion Middleware - Version to [Release Oracle11g]
Linux x86
Linux x86-64


The Configuration Wizard of a FMW 11g installation is very slow on a Linux environment. The Configuration Wizard can take +1 hour to configure components.

Most of the time is taken starting WLS managed servers. A jstack <pid> of the WLS managed servers shows always the following stack:

After the configuration wizard has completed, starting the environment is also very slow. Starting 3 managed servers can take around 15 minutes.


The Linux operating system is running on a virtual environment like Oracle VM, Oracle Virtual Box, VMWare or Xen.

The problem can also happen on a non-virtual environment, although it should be much less common. In case of doubt, the thread dump obtained with kill -3 or jstack will confirm if you are hitting this problem.
