The library used for random number generation in Sun's JVM relies on /dev/random
by default for UNIX platforms. This can potentially block the WebLogic SIP Server process because on some operating systems /dev/random
waits for a certain amount of "noise" to be generated on the host machine before returning a result. Although /dev/random
is more secure, BEA recommends using /dev/urandom
if the default JVM configuration delays WebLogic SIP Server startup.
To determine if your operating system exhibits this behavior, try displaying a portion of the file from a shell prompt:
head -n 1 /dev/random
If the command returns immediately, you can use /dev/random
as the default generator for SUN's JVM. If the command does not return immediately, use these steps to configure the JVM to use /dev/urandom
