The Java – Weblogic management console is too slow
I have installed Weblogic 10.3 3. A simple domain is configured using the default configuration After starting Weblogic, I can't use it through the administrative console because it starts too slowly (about 10 minutes) The management console application does not appear to be deployed correctly Even if I enable "temporary" mode in the adminconsole deployment option, it will not help Does anyone have a way to solve this problem? It really bothers me
Configuration properties:
Server: Dell PowerEdge r410 server (six core Intel) ® Xeon ® x64cpu,8GB RAM)
Operating system: Ubuntu maverick 10.10 x86_ sixty-four
Weblogic:10.3. 3 x64 (wls1033_generic.jar file for installation)
Java:1.6. 0_ 17_ I586 (try different jdks, including x64, but it doesn't work)
Solution
The result is that Weblogic uses a random number generator during startup Due to an error in Java, it reads random bits from / dev / random/ Dev / random has almost no problem, but it is very slow Sometimes it takes 10 minutes or more to generate a number There is a simple solution – use / dev / urandom It's not as good as / dev / random, but at least it's instant
The problem fix is very simple - exporting strings to Java_ Options = "– DJava. Security. EGD = file: / dev /. / urandom" added to / etc / bash Bashrc file Use / dev // Urandom, rather than simply / dev / urandom, is another hack Otherwise, the JVM does not understand the option value
If you try to set up Weblogic under UNIX based operating system, please pay attention to this problem
