Hi Notes Gurus!

Can somebody guide me on how to use LEI Activity? Should i be using Polling rather than replication? Please advise. Thanks!

Here's my problem:

I created 5 LEI Replication Activities:

 - 4 activities will replicate data (header and detail files) available (uses status as filter) from LN database to AS/400 (DB2), for processing at back-end.  I encountered error when i set them to run independently and always causes server downtime.

- the other 1 activity is to replicate the data from AS/400 (DB2) to LN to be able to update the status onced processed.

I changed the design to run them sequentially, using dependent activity.  Is it right to disable succeeding activities and only the 1st or main activity will be enabled?  How about the retry option, i tried to set the activities to re-run every minute, every 3 minutes, even tried to set them with different intervals, and yet i still encounter this error:
