Re: Data Pump and compress on the fly in Unix

I opened a tar specifically asking if ZFS was supported. The analyst came back and stated explicitly that it was not supported. When I pressed the analyst for more information, basically I got the response that Oracle will try, but not commit, to support us if we use ZFS, but they (Oracle) would not "certify" this configuration. At that point I passed the information along to management, and I am not sure which direction we are headed.

Yes, ZFS is a filesystem (and a volume manager rolled into one). It has a 'compress' option so it can be either compressed or uncompressed. I'll try to post a couple of examples in my blog either today or this weekend.

To the best of my knowledge (meaning I could be wrong), Oracle does not certify against a filesystem unless that filesystem is a cluster filesystem. They certify against the OS release so they don't specifically state that ZFS is certified in their site. But I've also read somewhere that sometimes, they will explicitly NOT support something (pxfs?). It's kinda confusing sometimes.. :(
