Setting

Description

Base Collection Strategy

From the drop-down list, select a pre-defined collection strategy. The Default Collection Strategy is the standard collection strategy that is used by default by the Disk and FTP agents.

The available strategies are:

Default Collection Strategy
Control File
Duplicate Filter
Multi Directory
TMO Full Collection Strategy

Note!

The Base Collection Strategy is the collection strategy that your APL Extension will be based on.

When saving your new collection strategy, make sure to use a descriptive name since it will be added to the list of available strategies in the agent's configuration.

The code that you see in the dialog is a default 'skeleton' set of function blocks that are already defined in the Base Collection Strategy. By adding APL code within these function blocks, you customize the way by which the collection is going to be handled by the workflow.

initialize
deinitialize
prepareBaseDirList
accept
filterFiles
preFileCollection
postFileCollection
begin
commit
rollback
