RE: Snapshots of QTREEs

Snapshot/SnapRestore works on volume basis and not on qtree level. 31 Snapshots mean, you can have 31 backup copies of the volume using Snapshots.

Good question. As far as I am aware of, a snap shot is ONLY Per VOLUME. -----Original Message----- From: Jay Newton [mailto:jnewton@chkenergy.com] Sent: 04 September 2001 21:05 To: 'toasters(a)mathworks.com' Subject: Snapshots of QTREEs Is there a way to snapshot an individual QTREE from command line or must it be the entire volume.

Is there a way to snapshot an individual QTREE from command line or must it be the entire volume.

Oracle I/O block size tuning
by Brian Tao 03 Sep '01

03 Sep '01

Our senior DBA asked about Oracle's block size and I/O chunk size settings... are there optimal settings for the two values when running over NFS to a filer (a pair of F740's in our case)? Our Oracle instances run on Solaris 2.6, talking NFSv3 over UDP to the Netapps with 32K block sizes. My first reaction was to say "you don't need to tune this", but what do people use? It sounds natural to me to use 8K block sizes and an I/O chunk size of 4 to take advantage of the 32K NFS reads and writes. Does it make a difference? -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

My Earlier e-mail to Toasters
by venkatesh sampath vankipuram 02 Sep '01

02 Sep '01

Hello, First of all I aplogize on e-mailing my resume to this mailing list on June 9-10 2001. I would bring to attention those who ridiculed my e-mail and making it sound real foolish, that maybe you also were looking for ajob one day and you too have your bad days. You did not fall off from the sky with a cushy desk job which you might be having now. I feel embarassed on being openly ridiculed in a company mailing list. Maybe I should talk to the "right" people ??. to Mr.Fred Berfl, maybe you are not a high powered technocrat, but i am sure you probably know how to use a mailing list to abuse someone else !. You dont have to organize a fundraiser to transport me to Cambridge,UK. Try e-mailing your thoughts about some one superior than you and pick on some one your own size. I am sure you are diligent enough!. Mr.Chris thompson, the same applies to you too. I respect Mathworks as being a great company and I dont want to be bullied by some people who think they are superior than others.Its a pity that this mailing list has characters who have utter disrespect for fellow human beings and their education and who want to display their superiority at every chance they get. I felt this e-mail was necessary to get my point of view across and I refuse to be treated like this for a small mistake of mine. I apologize once again for my unsolicited e-mail on June 10,2001 with subject "Resume" Hope my email drills some sense into some thick skulls ! Venkatesh

RE: Mass chown + preserve NT ACLs

Brian, You could use a third party NT tool like Small Wonder's "Security Explorer" to backup the NT ACL's on the whole tree then restore them when you have completed the uid and gid changes.

Brian, I believe it depends on what you want to be as a result at the end. If you'll flip the qtree to ntfs, do the chown, you will end up with ACLs. What do you want the files to be at the end - with or without ACLs ? Eyal. ----------------------------------------------------------------- eTraitel - I'm the new eBuzzword around !!!
