So to add some more color here, after further analysis on this, a teammate of mine noted that the Admin account had permissions to the AG in Test but NOT in PROD.
Having previously tried to load the failed load file in Test, I knew it worked there.
So on a hunch, I added the Admin to the permissions group as “Administrator” in PROD, set up just as it was on the AG in Test.
I attempted to reload the statements, and they loaded like a charm. And this worked on 2 AGs that had just started failing??
My IBM Case Support is one of the best guys at CMOD Support, and he, like I don’t think Admin access is required, and we have several AGs that don’t have Admin in the perms and they have been loading just fine.
Also, these AGs that JUST started failing have been running without fail or change to them for years?!?!?
I at least wanted to share that my solution so far has been the security change as noted.
These are NOW loading like Champs...
