Wait-For-File activity properties

In addition to the General and Triggers pages, The Properties dialog box for a wait-for-file activity contains a Wait For File page.

The Wait For File page contains:

Filename. The full pathname of the file that the activity is to wait for. The Arrow button offer you the choice of browsing for a file or inserting a job parameter whose value will be supplied at run time. For a job parameter, you can click the Browse button to open the External Parameter Helper, which shows you all parameters available at this point in the job sequence. Parameters entered in this field needs to be delimited with hashes (#). Parameters selected from the External Parameter Helper will automatically be enclosed in hash symbols.
Wait for file to appear. Select this if the activity is to wait for the specified file to appear.
Wait for file to disappear. Select this if the activity is to wait for the specified file to disappear.
Timeout Length (hh:mm:ss). The amount of time to wait for the file to appear or disappear before the activity times out and completes.
Do not timeout. Select this to specify that the activity should not timeout, i.e, it will wait for the file forever.
Do not checkpoint run. Set this to specify that IBM® InfoSphere® DataStage® does not record checkpoint information for this particular wait-for-file operation. This means that, if a job later in the sequence fails, and the sequence is restarted, this wait-for-file operation will be re-executed regardless of the fact that it was executed successfully before. This option is only visible if the sequence as a whole is checkpointed.
