Weblogic Server Is Too Slow

In Oracle Weblogic, sometimes our services open slower than expected, even if it is opened, the “7001/console” screen makes us wait.

I did a little research on some servers not having these waits on some servers.

Example log as below

Now let’s come to the reason; After Weblogic services are installed on Linux, when opening, it generates a random number for security reasons and processes it to the services and affects the performance of the startup.

This number generation is done with the ” /dev/random ” command. If you want to test it yourself, you can check the turnaround time on your own server by using the “head –n 1 /dev/random” command.

Like me, if your wait times are longer than necessary, we will shorten them with ” dev/urandom ”.

First of all, we enter the java.security file with the VI editor.

Find and replace this line.

In its place

You will see the difference when you turn off all services and turn them back on.
