My Environment

Wls version: 10.3

OS Version: redhat6.5

Problem description

After weblogic restarts the service, it takes a long time to enter the user name and password in the console, and it takes more than seven or eight minutes.

Problem Analysis

The problem analysis is posted in the post of this great god.

Let me give a general summary.

Weblogic requires the system to generate a random number for weblogic to use after entering the username and password.

In linux or some unix systems, the/dev/random and/dev/urandom devices are used to generate random numbers. By default, jdk calls random.

Urandom is not highly secure than random, but it takes time to generate random numbers.

Weblogic was used once at the first startup, so we had to wait for such an interval, that is, we got more than seven or eight minutes from the console.

Solution

Modify the $ JAVA_HOME/jre/lib/security/java. security file,

Replace securerandom. source = file:/dev/random or securerandom. source = file:/dev/random (which is the first in my environment by default)

IsSecurerandom. source = file:/dev/./random
