The OpenEdge DBA Files

New DBA Series: No More AIxcuses – Part One

Unless it’s a read-only database, no OpenEdge production database should run without after-imaging. Period.

After-Imaging (AI) is an OpenEdge continuous change logging system that stores database changes in specially formatted log files.

Nice uppercut in the first round. When people talk to me about their high availability measures, I think about Marvis Frazier. Good looking guy.
