Re: Duplicating with rman
Hi,
I'm not sure why your RMAN output says

Where's the ) reuse shown in your RMAN script? Are you sure the script you

RE: OEM permissions
Hi, I think you're describing a real security hole. But I'm not sure how it's exploited exactly. Let's say John Doe sets up his database on his desktop, which is part of the production database network. He sees the hash value of SYSTEM's password on production and sets the hash value for his own SYSTEM user to be the same. Since now he doesn't know the clear text password for SYSTEM (Pete Finnigan may know how to find it, though), he can't easily create a private database link owned by SYSTEM. He can still create a public link, or a private link owned by somebody else, his SYS user e.g. Then what? (He can still create a link owned by SYSTEM from another account such as SYS using a little bit hacking. But he won't know SYSTEM's password. I don't know how security of the production database is compromised in any way) Yong Huang you wrote: Maybe I'm a being a bit touchy here; but it seems that my comments about having access to dba_users went completely unnoticed. Let's put it this way: There is NO WAY you can prevent somebody from setting up their own private oracle instance.

Thanks in advance John Author: John Blake INET: [EMAIL PROTECTED] John, any chance that you can create those 4 datafiles on 4 different mount points and re-test? at first glance, without knowing a thing about AIX, I'd say that you are having thrashing problems across the multiple datafiles. As Jared indicated, the 10046 trace should show you each wait. Usually, you'll see small waits when working on a drive track, and then a larger wait when a seek across tracks occurs. The waits should list what file# is being written to (or read from). This may sound funny, but what does the server sound like when this load is running? Its pretty easy to tell the difference between a drive writing serially, and one that is covering 8 GB of surface area every second. How many segments are you loading into, are you sure that 1 MB extents are a good size? I'm a fan of keeping files to 1 GB, so that compression and transfer aren't such a pain, but then again the largest db that I work with is under 100 GB. A File size of 2000 MB scare me, bugs in the past with 2 GB files. Pd __ Do you Yahoo!?

RE: OEM permissions
You could use protocol.ora to specify which machines are allowed to make a connection to the database. In some environments this would be fairly painless. SAP for example. The users do not connect to the database, they connect to the app server. The number of machines that legitimately require a connection to the database could be very limited. This would reduce the possibility of someone sneaking in through a database link. Jared On Sat, 2003-12-20 at 12:29, Yong Huang wrote: Hi, I think you're describing a real security hole.

Re: Hit Ratio
Actually, it isn't SAP. I was simply creating a set of MV's based on SAP tables in another database. The script I was running is used to keep track of how much IO is going on, just to ensure that everything is still working during the build. Once the physical IO exceeds the logical IO, the HR goes negative. I wonder what I need to tune to fix this? Jared On Sat, 2003-12-20 at 03:29, Nuno Souto wrote: D Unreal, eh? that's SAP for you...

I believe the point is not that you can create links to SYS or SYSTEM accounts, but instead to application accounts, e.g. if I created a link from my private database to the company's HR database using a duplicated HR_MANAGER schema, I may be able to access data that I otherwise should not have. -- Tom Thomas A.
