You need to make sure that a JMS Message never expires. What value should you set for the JMSExpiration header? (Choose the best answer.)
Answer options:
A. 0
B. 999
C. 1000
D. 1
Answer correct:
A
WebLogic JMS calculates the JMSExpiration value as the sum of the application`s time-to-live and the current GMT. If the application specifies time-to-live as 0, JMSExpiration is set to 0, which means the message never expires. Reference: https://docs.oracle.com/cd/E13222_01/wls/docs90/jms/fund.html
