I have a client the is using ODBC to import/export shipping information from the UPS Worldship. This has work for them for years, until recently we had to replace their AS400. They went from a 170 V4R5 to another 170 V5R1. Only the user libraries were restored to the replacement everything else like the profiles and devices had to be manually configured.
So after everything was set back up on the replacement we tested the import/export on the UPS and it still work with no problem, except every once in awhile the export (UPS --> AS400) pops up the error "CWBC01049 The iseries server application is not started." and that shipment information does not reach the AS400.
There is no specific day or time when this happens. Sometimes it will not happen for a week or two and sometimes it will happen a few times a day a few times a week.
Has anyone ever had this problem or ell me where to begin to look. I've tried looking through jobs logs but can not seem to find what is causing the connection issue.
