Overview
OMS is a UNITY extension that allows for outbound emails to be sent from the extensions programs. Its known major usages are:
- Email order confirmations for POS orders
- Remittance advices
- An email version of the catalogue, where the catalogue is written to the email body (quite horrible).
Design
The main tables are:
- OMSQUEP (OMS-Outbound Message Queue File)
- OMSMHDP (OMS-Outbound Message Header File)
- OMSLINP (OMS-Outbound Message Lines File)
- OMSOUTP (OMS-Outbound Message Holding File)
Program flow:
- Job OMSPOSTPRD runs OMSNEP01CL (OMS-Process Outbound Email Msgs), a CL program. This runs all day in subsystem OMSSUBPRD.
- OMSNEP01CL calls RPG program OMSNEP01 (OMS-Process The Outbound Email Msgs for OMS System). This takes lines from OMSLINP and writes them
- OMSNEP01 calls OMSCRTFL (OMS-Create The IFS File For Domino Process) to create an IFS file for the database record (file member). This file goes into /omsfiles.
- OMSNEP01CL issues the Domino command
TELL AMGR RUN "OMSMAIL.NSF" 'OMS3-4'and then goes into a never-ending job, activating every 7 minutes.
OMSMAIL Domino agent
The CL/RPG side of OMS produces a text file in /omsfiles. A Domino agent (written in LotusScript) is what actually parses the contents of this file. It then builds and sends the email, deletes the IFS file, and SQL-updates the OMS tables. The script is located in /domino/maggie/data/. It can be viewed/edited in HCL Designer.
