findEJBTimers command

The following examples illustrate how to use the findEJBTimers command to find EJB timers and explain the output statement. For relevant parameters and syntax information, read about the timer service commands.

To find all EJB timers on a server called server1, enter in the profile_root/bin directory:

findEJBTimers server1 -all

To find all EJB timers on server1, associated with the Increment bean in the DefaultApplication, enter in the profile_root/bin directory:

findEJBTimers server1 -app DefaultApplication.ear 
                      -mod Increment.jar -bean Increment

When EJB timers matching the filter criteria are found, the output appears similar to the following:

EJB Timer : 252     Expiration: 5/25/10 10:53 AM     Single
   EJB    : TimerPtestApp, TimerPtestEJB.jar, NoMoreTimeoutsBean
   Info   : Single
   Programmatic timer
EJB Timer : 253     Expiration: 5/25/10 11:47 AM     Calendar
   EJB    : TimerPtestApp, TimerPtestEJB.jar, NoMoreTimeoutsBean
   Automatic timer
Calendar expression: [start=null, end=null, timezone=null, seconds="52",
           minutes="47", hours="11", dayOfMonth="25", month="5", dayOfWeek="*",
           year="2010"]
2 EJB Timer tasks found

In this output, the following elements exist:

• EJB Timer is the unique identifier of the timer.
• Expiration is the next time the timer is expected to execute.
• Calendar expression is the calendar expression that defines the timer expiration intervals and frequencies, if the timer expirations were defined by a ScheduleExpression. All automatic timers have expirations defined by a ScheduleExpression.
• EJB Key is the toString() method output of the primary key for and entity bean. For other EJB types, Not Available will be output.
• Info is the toString() method output of the object passed by the application when the EJB timer was created.

Only the first forty bytes of toString() output are displayed for the primary key and timer information. This information is only useful if the application overrides the toString() method for these objects.
