I've tested it 3 times for the import process. Works like a charm for me, but I'm only using 2 8GB data files. I'll see if I can get a test environment for data guard to try to test this.

There can be glitches and as the process can take a long time - if you are copying large tablespaces you might not get many test attempts. My mistake was not to have a test area set up to iron out any glitches. 2009/12/7 SHEEHAN, JEREMY <JEREMY.SHEEHAN@xxxxxxxxxxxxxxxxx<mailto:JEREMY.SHEEHAN@xxxxxxxxxxxxxxxxx>> Hey all, I'm going into my first round of transportable tablespaces. I've done the work, got it working with relatively no problems. I was certainly concerned at first when I read how easy it was to do this... Naturally it made me somewhat wary. I'm ready to migrate this on over to production, but I have a Data Guard/Physical Standby configuration with my prod environment. My question is this... Is it really as easy as just moving the data files to the standby server and letting Oracle take it in? Again, it seems so simple that it makes me wonder if there is more involved, you know? If anyone can shed some light on this, that would be fantastic! Thanks in advance! Jeremy Consider the environment. Please don•'t print this e-mail unless you really need to. -- Howard A. Latham
