WebLogic Server 10.3.x takes long to startup on RHEL 5.x. About 7 mins then eventually comes up in running mode. After this when you enter username and password on the WLS console, it takes 5-8 mins to come up.
Issue is that OS was running out of random number generation, and that caused the delay in startup. Following solutions will resolve this issue.
1) mv /dev/random /dev/random.ORIG ; ln /dev/urandom /dev/random
Note: The above mentioned solution is not recommended, though it does the job.
2) Add “-Djava.security.egd=file:///dev/urandom” to java parameters (JAVA_OPTIONS in setDomainEnv.sh file).
