Attributes Summary

serviceNames : EString Specifies a list of services to make available to this work manager.

minThreads : EInt The minimum number of threads available in this Work Manager.

maxThreads : EInt The maximum number of threads available in this Work Manager.

threadPriority : EInt The priority of the threads available in this Work Manager

numAlarmThreads : EInt Number of alarm threads for the Alarm manager.

isGrowable : EBoolean Specifies whether the number of threads in this Work Manager can be increased.

defTranClass : EString The default transaction class is only valid for zOS platform.

daemonTranClass : EString Daemon transaction class only valid for zOS platform

workTimeout : EInt Specify the timeout value for a Work that is executing, Default value is 0 which means no work time out is enabled. The unit of the time is in milliseconds.

workReqQSize : EInt Specifies the size of the buffer that the Work Manager's thread pool uses to pull requests from. The total number of in-flight requests will be the sum of Max Threads and this wrok request size. If this value is not set, then the queue size is undefined. The value range is 1 to (2^32)-1. Notes: Use with extreme caution. Specifying a large value can lead to instability and memory resource issues.

workReqQFullAction : EInt Work request queue full action. Possible values: 0 - block; 1 - fail. If 0 is specified and the thread pool is unable to immediately allocate a thread or a free slot in the buffer, the request will block indefinitely until a thread becomes available in the pool. This is the default behavior. If 1 is specified and the thread pool is unable to immediately allocate a thread or a free slot in the buffer, a WorkRejectedException with an error code of WorkRejectedException.WORKREQUEST_QUEUE_FULL will be thrown. The request can be retried until successful. The WorkRejectedException may be thrown any time where a thread cannot be immediately be allocated and may not reflect the size of the thread pool and buffer.

isDistributable : EBoolean If false, Work started with this Work Manager will not be distributed to other cluster members. If true, Work may optionally execute remotely if the Work is distributable.
