Timer service commands

Information about EJBs timers is generally specific to the application that creates the timers, and the timers are not visible outside of the creating application. Therefore, management of EJB timers should be performed by the application that contains the enterprise bean and that creates the EJB timer.

However, we can use the following commands during application development. They provide some basic EJB timer management functions. These commands are not available on client only installs.

 

findEJBTimers

This command displays information about existing EJB timers based on specified filter criteria. The syntax for this command is:

findEJBTimers server filter [options]
   filter: -all | -timer | -app [-mod [-bean ]]
           -all
           -timer timer id
           -app   application name
           -mod   module name
           -bean  bean name

  options: -host  host name
           -port  portnumber
           -conntype connector type
           -user  userid
           -password password
           -quiet
           -logfile filename
           -replacelog
           -trace
           -help

where :

server

the name of the server process where the EJB timers are located

-all

find all EJB timers associated with the server process

timer id

EJB Timer ID that uniquely identifies the timer

application name

find all EJB timers associated with the application

module name

find all EJB timers associated with the module

bean name

find all EJB timers associated with the enterprise bean

host name

host name of the server process

portnumber

port of the server process

connector type

type of connection. For example, SOAP, RMI, or NONE.

userid

user to use when connecting to the server process

password

password to use when connecting to the server process

quiet

disable output

logfile

directs output to a file

replacelog

clears the existing log before executing the command

trace

enable trace

help

provides command-specific help

If the server you specify is configured to use a scheduler instance that is shared by multiple servers, then EJB timers created in any of the server processes might be found.

For an example of the findEJBTimers command, see FindEJBTimers command example.

 

cancelEJBTimers

This command cancels and removes from persistent storage EJB timers based on the specified filter criteria. The syntax for this command is:

cancelEJBTimers server filter [options]
   filter: -all | -timer | -app [-mod [-bean ]]
           -all
           -timer timer id
           -app   application name
           -mod   module name
           -bean  bean name

  options: -host  host name
           -port  portnumber
           -conntype connector type
           -user  userid
           -password password
           -quiet
           -logfile filename
           -replacelog
           -trace
           -help

where :

server

the name of the server process where the EJB timers are located

-all

find all EJB timers associated with the server process

timer id

EJB Timer ID that uniquely identifies the timer

application name

find all EJB timers associated with the application

module name

find all EJB timers associated with the module

bean name

find all EJB timers associated with the enterprise bean

host name

host name of the server process

portnumber

port of the server process

connector type

type of connection. For example, SOAP, RMI, or NONE.

userid

user to use when connecting to the server process

password

password to use when connecting to the server process

quiet

disable output

logfile

directs output to a file

replacelog

clears the existing log before executing the command

trace

enable trace

help

provides command-specific help

If the server you specify is configured to use a scheduler instance that is shared by multiple servers, then EJB timers created in any of the server processes might be cancelled.
