Directory Scanner – Error Handling (Magic xpi 4.13)

The Magic xpi Server Flow Manager checks for errors during the execution of a step. If there is an error in a Directory Scanner component step, the Error Handler is invoked and handles the error.

The first error in the step causes the termination of the step execution. If the step has multiple methods, and an error occurs in one of these methods, all subsequent methods are not executed.

For Directory Scanner steps: While executing any method on the FTP server, if there is a connection error (Socket Exception), the Reconnection Policy (the Number of login retries and Delay between login retries parameters in the FTP Resource) is applied:

• If the reconnection is successful, then the process is continued.

• If the reconnection fails, then the process is terminated and an error message is shown in the Monitor.

For Directory Scanner triggers: The Directory Scanner connects to the FTP server to Get the directory listing. If the connection is successful, it processes each file in the list one after the other. If there is a connection error (Socket Exception) while Getting the Directory Listing, the Reconnection Policy is applied:

• If the reconnection is successful, then a message is shown in the Monitor and the process is continued.

• If the reconnection fails, then a message is shown in the Monitor and the Directory Scanner trigger is delayed for the Polling Interval (as specified in the configuration) and continues for the next processing cycle.

The error codes for the Directory Scanner component are listed below. You can also use Magic xpi's General Component Errors with the Directory Scanner component. The codes are returned to the Magic xpi Server in the Invocation program’s Error Code parameter.
