The following examples illustrate how to use the findEJBTimers command
to find Enterprise JavaBeans (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 the following command in the
<install-root>\profiles\<profile>\bin directory:
findEJBTimers server1 -all
To find all EJB timers on
server1,
associated with the
Increment bean in the
DefaultApplication,
enter the following command in the
<install-root>\profiles\<profile>\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.
