When you start a broker or client with SSL, you may notice a sharp increase in CPU usage for a few seconds. This is because the JSSE (Java Secure Socket Extension) method java.security.SecureRandom, which Message Queue uses to generate random numbers, takes a significant amount of time to create the initial random number seed. Once the seed is created, the CPU usage level will drop to normal.
Start the broker, providing the keystore password.
Put the keystore password in a password file, as described in Password Files and set the imq.passfile.enabled property to true. You can now do one of the following:
Pass the location of the password file to the imqbrokerd command:
imqbrokerd -passfile /passfileDirectory/passfileName
Start the broker without the -passfile option, but specify the location of the password file using the following two broker configuration properties:
If you are not using a password file, enter the keystore password at the prompt.
You are prompted for the keystore passwrd.
