General activitiesIntroductionThe General Activities palette contains several general-purpose activities and process starters. For example, the Timer process starter is used to start a process at a specific time.The activities are also used for error handling design time activities.The activities also contain some engine level activities like engine command , checkpoint etc.WISHTREE TECHNOLOGIES CONFIDENTIAL: This document is for your company's internal use only and may not be copied nor distributed to another third party.ActivitiesActivity IconsActivity NamesDescriptionAssignThe Assign activity allows you to assign a value to a user-defined process variable. When the Assign activity is executed, the entire schema for the selected process variable is replaced with the specified values.Call ProcessThe Call Process activity calls and executes an existing process definition. The input to the called process is defined in the Start activity of the called process. The output of the called process is defined in the End activity of the called process.CatchThe Catch activity receives control of execution when an unhandled exception occurs. You can select a specific exception type to catch or you can specify that this activity should catch all unhandled exceptions. You can have more than one Catch activity in each exception scope, but each Catch activity must have a unique exception type.CheckpointThe Checkpoint activity performs a checkpoint in a running process instance. A checkpoint saves the current process data and state so that it can be recovered at a later time in the event of a failure.ConfirmThe Confirm activity confirms any confirmable messages received by the process instance.

If there are no error transitions, the process instance halts execution. This activity is useful in a group or in a called process.Get Shared VariableThe Get Shared Variable activity retrieves the current value of a Shared Variable or Job Shared Variable resource.InspectorThe Inspector activity is used to write the output of any or all activities and process variables to a file and/or stdout.Job Shared VariableA Job Shared Variable shared configuration resource allows you to store data for use by each process instance. A copy of the variable is created for each new process instance.Lock ObjectLock Object shared configuration resources are used by Critical Section groups to ensure that only one process instance executes the activities in a critical section group at a time. MapperThe Mapper activity adds a new process variable to the process definition. This variable can be a simple datatype, a TIBCO Active Enterprise schema, an XML schema, or a complex structure. Map data values from the current list of process variables to the elements of the variable added in it.

This activity has a name and a description specified on the Configuration tab, but there is no input or output for the activity.RethrowThe Rethrow activity throws the exception caught by the Catch activity again. Use this activity when you wish to propagate the exception to the next level.Set Shared VariableThe Set Shared Variable activity allows you to change the value of a shared variable.Shared Variable

A Shared Variable resource allows you to share data across process instances.SleepThe Sleep activity suspends the process on the current transition for the given amount of time. If you have multiple control flows in your process, only the current execution branch of the process is suspended.
