Oracle Support

1. Feed the /dev/random device with additional I/O operations or using a random number generator tool (like rngd).

2. Instruct WebLogic server to use a non-blocking entropy device.

2.1 Long term solution

a) WebLogic Server Scope

i.   Edit the Weblogic startup script ($DOMAIN_HOME/bin/startWebLogic.sh)

ii.  Add the following to the JAVA_OPTIONS variable: -Djava.security.egd=file:/dev/./urandom

iii. Save the file.

iv. Set the domain environment. ($DOMAIN_HOME/bin/setDomainEnv.sh)

v.  Start WebLogic instances.

b) JDK Scope

i.   Edit the Java Security Properties file ($JAVA_HOME/jre/lib/security/java.security)

ii.  The securerandom.source property specifies the source of seed data for secure random. If that property points to /dev/random, set it as one of the options listed below.

securerandom.source=file:/dev/./urandom

securerandom.source=file:/dev/urandom

iii.  Save changes and start the WebLogic Server instances.

2.2 Temporary solution (usually applied for testing purposes)

i. Override the JAVA_OPTIONS environment variable before starting WebLogic Server via shell scripts.

$ export JAVA_OPTIONS="${JAVA_OPTIONS} -Djava.security.egd=file:/dev/./urandom"

ii. Start WebLogic instances.
