14.14.5 Defining an Expiration Logging Policy
The following section provides information on the expiration policy. The Expiration Logging Policy parameter has been deprecated in this release of
WebLogic Server. In its place, Oracle recommends using the Message Life Cycle Logging feature, which provide a more comprehensive view of the basic events that
JMS messages will traverse through once they are accepted by a JMS server, including detailed message expiration data. For more information about message life cycle
logging options, see Message Life Cycle Logging in Configuring and Managing JMS for Oracle WebLogic Server.
For example, you could specify one of the following values:
■
JMSPriority, Name, Address, City, State, Zip
■
header, Name, Address, City, State, Zip
■
JMSCorrelationID, properties The JMSMessageID field is always logged and cannot be turned off. Therefore, if the
Expiration Policy is not defined that is, none or is defined as an empty string, then the output to the log file contains only the JMSMessageID of the message.
14.14.6 Expiration Log Output Format
When an expired message is logged, the text portion of the message not including timestamps, severity, thread information, security identity, etc. conforms to the
following format:
ExpiredJMSMessage JMSMessageId=MESSAGEID HeaderFields Field1=Value1 [Field2=Value2] … ]
UserProperties Property1=Value1 [Property=Value2] … ] ExpiredJMSMessage
where MESSAGEID is the exact string returned by Message.getJMSMessageID. For example:
ExpiredJMSMessage JMSMessageID=ID:P851839.1022176920343.0 HeaderFields JMSPriority=7 JMSRedelivered=false
UserProperties Make=Honda Model=Civic Color=WhiteWeight=2680 ExpiredJMSMessage
If no header fields are displayed, the line for header fields is not be displayed. If no user properties are displayed, that line is not be displayed. If there are no header fields
and no properties, the closing ExpiredJMSMessage tag is not necessary as the opening tag can be terminated with a closing bracket .
Tuning WebLogic JMS 14-19
For example: ExpiredJMSMessage JMSMessageID=ID:N223476.1022177121567.1
All values are delimited with double quotes. All string values are limited to 32 characters in length. Requested fields andor properties that do not exist are not
displayed. Requested fields andor properties that exist but have no value a null value are displayed as null without single quotes. Requested fields andor
properties that are empty strings are displayed as a pair of single quotes with no space between them.
For example: ExpiredJMSMessage JMSMessageID=ID:N851839.1022176920344.0
UserProperties First=Any string longer than 32 char ... Second=null Third= ExpiredJMSMessage
