Before we start: if you’re a technical person reading this, please forward to your boss, your boss’ boss and your boss’ boss’ boss. Forward it all the way up the org chart. Print it out and tack it to the bulletin board in the cafeteria. Make sure no one in I.T. management or at the C-level can pretend they didn’t know.
If you read Part I, you’ve already analyzed your data and designed your Type II storage areas and you’re ready to dump your existing data and load it into the new structure. If you’re still using Type I storage areas, this will probably be the slowest part of the entire D&L process so don’t despair. The load and the index rebuild should take considerably less time than the dump.
Picture a Rubik’s cube in your mind: at the core is the holy grail of system performance, and every colored tile is a potential bottleneck preventing you from attaining that perfection. On one side, you find database issues, another side is the network, there are the physical servers, and mixed throughout is plain old bad code. Today we’ll focus on a few big red flags related to your physical system resources: CPU, memory and disk.
Congratulations! You finally decided to join the modern world and take advantage of Type II Storage Areas (SAII). Hey – better late than never. There’s a lot of old, out-of-date or just-plain-wrong information out there, so ignore all that stuff. I have conveniently digested some useful, pertinent and correct information right here.

The reason is simple, of course: cost. Unless your OpenEdge application is serving thousands of users, Linux can probably do the job just as well as one of the proprietary Unix flavours. If you have less than 250 concurrent users then this should be a no-brainer for 98% of you.
I was called in to consult at a site where the backups were exhibiting strange behaviour. The backup file was the normal 15Gb in size and the time stamp was from last night, but when they restored it in test there was no new data. In fact, the most recent data they could find was from a couple of weeks ago.
