Informatica - Difference between STOP and ABORT

Informatica - Difference between STOP and ABORT

1. Process:
The main difference between STOP and ABORT is process timeout period.

STOP:
It will stop reading from the source. But it will continue updating/committing changes in the target.

ABORT:It is same as that of STOP. But ABORT has the timeout period of 60 seconds. If the session fails to update/commit the changes in the target before 60 seconds then the session will be compulsarily aborted by terminating the DTM process thread.

2. Memory release:

STOP:
STOP will release the memory block that was occupied by the session properly.

ABORT:
ABORT will not release the memory immediately (taken care of other memory release mechanisms).

3. Consistency:

STOP: Stop will try to rollback to ensure the consistency of data.

ABORT: It will kill the process immediately and can not be rolled back. (Equivalent to UNIX kill -9)
