RE: copy a datafile to a raw device

2003-06-22 Thread Hemant K Chitale
Stephen / Gene, Actually there is no difference between Raw Devices and File Systems when Oracle reads/writes Oracle Blocks. It is the OS interface that is different -- Character-device or Block-device. Most OSs include a header portion in a Raw Device which must be skipped because when Oracle

Hi Arup, Thanks for the reply, I agree with you that ops$ accounts are definitely weaker than database authenticated accounts. I would always advocate trying to find another way to allow access if possible, i understand that in some cases remote authentication is what an organisation chooses to

No, that's not true. It actually uses your NT security token to validate that you are authenticated in the domain. You can't just give a rogue PC the same domain name, boot it up, and log into the database with external authentication. The PC would have to be a domain member, which means you

Because external authentication checks the domain name you are logged into. You can't log into a local user JKILCHOE and connect to the externally authenticated database user MYDOMAIN\JKILCHOE. Beth -Original Message- Sent: Friday, June 20, 2003 4:05 PM To: Multiple recipients of list

Hi Pete, I don't think that's true about booting a PC with the same domain name that's not really part of the domain. Have you ever tried it? I'd be really interested if it works. I don't understand the part about booting into Linux and changing the username as its sent. Isn't the only

I have had some recent exposure to Access - people asking me to investigate why their query runs for so long. I can understand that if one table in the query is local then Access has to pretty much work locally, but I have been terribly surprised at how it approaches multi-table queries some

Hi, I don't remember seeing any doco as such, but you need to look at what's new in RAC and compare it to OPS. eg. No pinging on read and write, easier admin. etc. Can't remember off the top of my head. Rgs, Leng. -- From: VIVEK_SHARMA [EMAIL PROTECTED] Date: Wed, 18

Well, the greatest novelty in RAC is synchronizing blocks without write to disk. Here is it how it works: OPS: 1. Instance A requests instance B to downgrade its (PCM) lock for block C from X -- N. 2) Instance B writes block C to disk and downgrades lock to N. 3) Instance A reads block C

Hi! It just adds one more tab storage layout to your OEM console. If you are running on EMC you can drill down physical storage information to see on which disks your datafiles actually reside. I haven't heard that they have it for Veritas yet... but I've not worked with it either, EMC has its
