Question on Mean Time To Recovery Advisor.

Howdy all. Im reading up on the MTTR Advisor and I don't really understand the point. From what Im reading
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14220/mgmt_db.htm ,
this is the desired length of time I want to wait when recovering from backup? That seems kinda goofy, of course I want to wait as short of time as possible. Why would anyone ever want to have a longer time specified as opposed to a shorter time?
TIA, ChrisR

Aaahhhhhhh....... so other DB's on the same box will suffer a performance hit. This makes sense, thanks!

Not a valid photoshop document after time machine recovery and reinstall of photoshop

After a time machine recovery most of my photoshop documents recovered fine, however there are a select few (and my most recent work unfortuantely) that seem corrupt. It isn't all of my documents. Trying to recover them again from back-up doesn't seem to be working. I did have to reinstall photoshop CS4 after the recovery.
I have seen similar questions on here but none of the solutions have worked. I've tried opening with other programs, I've tried changing the file extentions etc. If the files were just corrupt recovering them from time machine should fix the problem. Many thanks if you can assist.

…but it doesn't feel like corrupt files are the problem…
If it's only a few selected files that are misbehaving but others do open without problems, then you do have file corruption in each of those files.
Go back in time machine to the earliest possible date after each file was created and restore only that particular version of the file.
If that doesn't work, then considered the files irretrievably lost. What kind of error message do they return when you try to open them?
In any event, it's imperative that you check the SMART status of your drive and Repair Drive (or at least Verify Drive) to check for a failing drive.
As an aside, taking a belt-and-suspender approach, it's my practice to supplement Time Machine with a clone of my working drive and daily backups of my files. For some reason, I've had three Time Machine disks fail on three different Macs and locations in the last six months or so.
I had Time Machine disabled on all my Macs until I decided to give it one more test run on a 65-lb Mac Pro recently. I'm not convinced one way or another yet, so all other Macs still have TM disabled for now. Time Machine is very intrusive, and the external TM drives run much, much hotter than external storage files—always a troubling sign in my book.

Hello Prasad,
Before attending interviews.....First you need to understand general things like CV writing, projects, sub modules etc., you should be gain knowledge on these concepts then you can move further.
1. CV 2.Projects 3.your strenths in sap (reading..reading...reading....practice...practice...practice)
2.you please interact with your friends who is on trails, then you can get more information like interview process, methodology, technical etc.,
I am sending some real time interview tech questions which will useful for you.
Questions:
1.When tickets are raised by end users who will give priority? After resolve the tickets who will close the status?
2.In real time at a time how many normal periods, special periods, MM periods we can open?
3.What is client dependant & Independent?
4.How to transport configuration settings from one client to another client or production client, which tools we can use for transport?
5.Why we donu2019t assign business area to company code?
6.What is the difference between General GL A/c, Control A/c, Reconciliation A/c & Offsetting A/c?
Answers:
1.The priority is generally decided by the Coordinator on the client side. After tickets are resolved, they will have to be closed by the coordinator on the customer site
2. In FI as many as you wants. In MM only 2 (current month + previous
3.Certain tables and customizations made in one client will affect the other clients also - then it is cross client i.e, client dependent. While if the changes made in one client has no impact on the other client - it is said to be client independent
4.Transports from one server to the other can be made with the help of transport requests. When a configuration is done the system generates a request number. First release the task and then release the request. Use TC-SE10 / SE09, SE09: workbench transport; SE10: customizing transport. But currently no such difference actually exists.
5.because in case of multiple company codes, same business area can be used across company codes. Business area is cross company code, means it is not confined to one company code thatu2019s why we don't assign BA to any of the company codes. It is client dependant, not company code dependant. We can pass values from one company code to any of the BA in that client.
6.General GL Account are those used for standard posting like for example Income and Expenses Accounts
- Control Account are basically used for reconciliation between modules like FI and CO, to ensure that both the modules are in sync.
- Reconciliation Account are those specific covering ADK (A-Assets, D-Customer, K-Vendor). For example a Customer Master would be mapped to a Bills Receivable Reconciliation Account and any transaction that needs to be posted are done against the customer code.
- Offsetting Account are used for variety of reasons and few examples are Intercompany Postings, at the time of Implementation when TB and Balance sheet are uploaded would be offsetted against a dummy account.
All the best.....dont forget and pl assign points if useful and if u have any querries pl revert back
thanks

(2) Remember font size setting
Are you using a feature of your email site to increase the font? If the site can't remember that for you, then there might be an indirect solution (a hack) to fix it. Which webmail site is it? There might be a userscript available.
If you mean Firefox's zoom setting, then Firefox should remember that between visits.

XMII Logic for calculating mean time

Hi All,
My xMII is connected to OPC and from OPC server I am getting the Status of few equipments. I am trying to calculate the mean time between failures. Let me be bit precise.
Lets take for example, an equipment called Reactor. The Reactor was in running status at 6:00. The status was failure at 6:15, again failure at 6:30. So, I have to track the mean time between two successive 'Failures'. If the time difference between two successive failures exceeds 15 mins, then an entry of that equipment is to be made into the database.
Can anybody help me out with a logic as to how should I proceed??
And please explain the steps in detail.
Thanks in Advance,
Lipsa.

If your OPC tag is a digital tag, you can se the totalizer block and some simple math to achieve this. But you'll need to read the documentation first, try it, then come back with questions!

Some questions about a Time Capsule

Hi!!
I just have a few questions about a Time Capsule, but first let me explain the backgroud to my questions.
I live in a 2 floor house(including a basement) and my bedroom is downstairs. My parents currently have a desktop PC connected to our wireless router and our printer. Me and my step-father both have 13 inch MacBook Pros, and he uses the Mac like a basic computer, so the equipment connected to our PC is good for him. I, on the other hand, use my Mac, iPad and iPhone to their fullest potential. I am a SUPER MEGA NERD when it comes to computers, so I plan on making my bedroom an amazing office at the same time. So I want an AirPrint Enabled printer in my bedroom (Under 100$$) along with a Time Capsule to back up my information, because everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
If you don't understand what I'm trying to ask (Even though I feel like it's self-explanatory)
ONE question about the PRINTER: Do any of you have any recommendations for an AirPrint Enabled printer under 100$? Even under-150$ would be okay.
THANKS FOR ANY HELP!!!!

everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
Don't just depend on TM.. use a disk image type utility.. either one of the Mac tools, SuperDuper, CCC, Chronosync or even a linux boot cd (if you have a cd/dvd drive still or via usb can boot) a great tool is Clonezilla.. it will do basically any computer, Mac, Linux, Windows.. and since it boots into its own OS can restore a computer in a flash. Then you can add the incremental changes from TM.
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
Actually I am surprised you get good wireless as usually directly above or below a router is often the worst spot. Time Capsule cannot extend the wireless of any other router than Apple.. it is a special system and only Apple can join the club. It has bad effect though, if you set the TC to extend wireless it turns off ethernet ports.. which is hugely dumb.
The best arrangement is ethernet to the upstairs.. or EOP adapters. If not then a wireless router that matches the existing unit will generally be better than mixing apple and non-apple.
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
You create a new wireless network by selecting manually the wireless channel and use different wireless name, ssid and security. There are 3 available channels on 2.4ghz.. your existing router will use one or two.. depending on if the setting is 20mhz or 40mhz.. so you need to manually set everything and not use auto.
TC is slow on 2.4ghz cf 5ghz and there are many more channels at 5ghz but not everything can use it.. iphone for instance is 2.4ghz only . whereas ipad can use 5ghz.. most full computers now can use 5ghz.
Buy a wireless network printer. Or alternatively an ethernet network would be also ok but now are more expensive than wireless ones. Network printers are not much more than straight USB and work much better.
I do not use airprint so have nothing to offer.. find the best HP model in your budget.. but others may have had more experience.. I use ethernet connected b/w laser business type HP.. they work great.. but airprint is too recent an innovation for me.

Can we ask more than one question at a time in Quick Poll?

Dear Experts,
Can we have more than one question at a time in Quick Polling.
The User has to answer more than one question in single poll.
is that possible?
Thanks in advance for your attention.
Regards,
Viswes.

Hi Viswes,
Through customize u can achieve ur requirement..
Create two Quickpoll with different campaign name and start ongoing..
Next create iview for each quickpoll by using KM QuickPoll iView Template enter the corresponding campaign name for the quickpoll iview.
Next create one JspDynPage component in NWDS
In that JSP file
<iframe src="Give the preview path of Quickpoll iView 1" align="left" >
</iframe>
<iframe src="Give the preview path of Quickpoll iView2 " align="left" >
</iframe>
Now u create one iview for that JspDynPage component
in that two Quickpoll question will display in one iView..

My iphone has been water damaged and in the mean time ive gone back to using my old phone. But i need to get all the contacts from my iphone i had synced to my laptop, but i don't know where to find them and im not sure if ive backed them up to anything!

my iphone has been water damaged and in the mean time ive gone back to using my old phone. But i need to get all the contacts from my iphone i had synced to my laptop, but i don't know where to find them and im not sure if ive backed them up to anything!

If your contacts are synced to your computer then they are in the supported app you are syncing with.
When you set up syncing of contacts on your device, which application did you select?

What does the folder with a question mark mean?

When I power on my black Macbook a white screen appears with a folder with a question mark flashing. what does the folder with a question mark mean? I just replaced the hard drive. When I put the install disc in the cd drive makes a very loud whirring noise then eventually the disc pops back out. Any ideas?

You will need to reinstall:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

You created your user ID today.
You asked "a question" today and received a response from user Chris CA.
Twenty minutes later, you created this post, which does not ask any question. It makes a statement, that is inaccurate!
So - you asked once. You did get a reply. If that reply did not answer your vague question, ask the poster to explain. It might help if you provided more information about why you are asking.

실수로 TABLE을 DELETE 또는 DROP한 경우 복구 방법 (time-based recovery)

제품 : ORACLE SERVER
작성날짜 : 2004-07-29
PURPOSE
사용자의 실수로 중요한 데이타를 delete 하였거나, 테이블을 drop하였을
경우 복구하는 절차를 정리한 자료이다.
Explanation
사용 중인 database 의 archive log mode 여부를 다음과 같이 확인 후
archive log mode인지 아닌지에 따라 복구 방법이 달라진다.
os>svrmgrl
SVRMGR> connect internal;
SVRMGR> archive log list
Database log mode ARCHIVELOG
Automatic archival ENABLED
Archive destination ?/dbs/arch
Oldest online log sequence 2525
Current log sequence 2527
1. Archive mode인 경우 복구 방법
archive log mode로 운영중이면서 full backup및 archive file들이 모두
존재하는 경우 복구가 항상 가능하다.
이때 다시 다음과 같이 두가지의 경우를 구분하여 복구 작업을 수행할 필요가
있으며 아래에 각각의 경우에 대한 절차를 자세히 설명한다.
(1) drop이나 delete한 시점이 얼마 지나지 않았거나, 혹은 필요에 의해
database 전체를 data 손실 이전 시점으로 돌리고자 하는 경우
(2) 손실된 data만을 drop이나 delete이전 상태를 받아내고, 나머지 data는
모두 drop/delete이후 발생한 transaction의 반영분을 유지시키기 위해
현재 시점으로 맞추어햐 하는 경우
1-1 database 전체를 drop이나 delete 이전시점으로 돌리고자 할 때
이러한 경우는 데이타 손실이 발생하기 이전의 datafile들에 대한 backup을
restore한 후 손실 발생 시점 직전까지 time based로 imcomplete recovery를
수행하면 된다.
(1) db를 shutdown시킨 후 현재 상태를 만약의 경우를 대비하여 cold
backup을 받아둔다.
shutdown immediate로 db를 내리고, datafiles, redo log files, control
files 모두 tar등의 명령어를 이용하여 backup을 받아둔다.
이것은 만약의 경우 이전 backup이나 archive file에 문제가 있는 경우,
삭제된 data의 복구가 불가능할 경우 현재 상태로라도 돌리기 위한
것이다.
(2) 데이타를 삭제하기 이전 상태에서 받아둔 datafile full backup을
restore한다.
redo log files과 controlfiles은 현재 것을 그대로 이용하고, 현재
상태의 모든 datafiles을 지우고 데이타가 삭제되기 전에 받아둔
backup datafile을 restore시킨다.
(temp datafile의 경우는 restore시간을 줄이기 위해 restore하지
않아도된다.)
(3) restore한 backup시점 이후의 archive file들을 archive log
destination에 위치시킨다.
full backup 이후의 archive file들을 일부 tape 장비등에 backup을
받아두고 지운 상태라면 그러한 file을을 다시 원래 위치에 restore
하여, full backup받은 시점부터 복구하고자 하는 시점까지의
archive log file들이 모두 log archive destination에 존재하는지
확인한다.
(4) 데이타 삭제 이전 시점까지 time based로 recover를 수행한다.
이때 날짜와 시간 지정은 항상 아래 예와 같은 형식으로 지정한다.
만약 데이타를 삭제한 시간이후로 지정하게 되면 recovery후에도
여전히 data는 지워진 상태로 보여진다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> startup mount;
SVRMGR> set autorecovery on
SVRMGR> recover database until time '2001-01-30:21:00:00';
SVRMGR> alter database open resetlogs;
(a) 만약 이때, controlfile이 현재것이 존재하지 않아 datafile뿐
아니라, controlfile도 과거것을 사용했다면, recovery command를
다음과 같이 지정하면 된다.
recover database using backup controlfile (아래줄과 이어짐)
until time '2001-01-30:21:00:00';
(b) temp datafile을 restore하지 않은 경우라면 startup mount수행
직후 다음과 같은 문장을 추가하면 된다.
alter databse datafile '/oracle/oradata/temp01.dbf'
offline drop;
/oracle/oradata/temp01.dbf는 temp datafile의 이름을 예로 든
것이다.
(5) 원하는 data가 제대로 조회되는지 확인한다.
1-2. 삭제된 data만을 복구하고 나머지는 현재 상태를 유지하고자 하는 경우
이러한 경우는 데이타가 삭제되기 이전 상태의 backup datafile 중에
SYSTEM, RBS와 삭제된 data가 들어있는 datafile만을 restore시켜 time
based로 recovery하여 db를 open시킨 후 원하는 table만 export를 받아낸다.
그리고 다시 현재 상태의 db에 export받은 내용을 import시키는 것이다.
이때 삭제된 data를 export받기까지의 절차에 대해서 다음과 같이 세가지
경우의 방법을 생각할 수 있다.
(a) 다른 시스템에 backup이나 test용으로 oracle이 설치되어 있는 경우
그 시스템에 backup을 restore하여 해당 table을 export 받는 방법
(b) 같은 시스템에 backup을 restore 하되, db name과 oracle_sid를 다른
이름으로 변경하여 다른 db를 만들어 recovery후 open하여 export받는
방법 <Bulletin:11616 참조>
(c) 현재 db는 cold backup받아 두고, backup을 restore하여 export을
받아내는 방법
여기에서 (a)의 경우는 다른 시스템에 이용하고자 하는 datafile의 oracle
version 이상의 oracle software가 이미 설치되어 있어야 한다.
(b)의 경우는 현재 상태의 cold backup을 받았다가 export받은 후 다시
현재 상태를 restore할 필요는 없애주지만, 대신 SYSTEM, RBS, user
datafile 만큼의 disk space가 추가로 필요하며, 새로운 db를 추가로
구성하는 것이므로 init.ora file 구성 등의 작업이 필요하다.
이것에 관한 자세한 절차는 <Bulletin:11616>을 참조하도록 한다.
이 자료에서는 이중 (c)에 대한 것만을 자세히 설명한다.
(1) 현재의 모든 datafiles과 redo log files, datafiles을 다음과 같이
신중히 cold backup을 받아두도록 한다.
이것은 이후에 삭제한 data를 복구하여 export를 받은 후에 다시 현재
상태의 db로 되돌아오기 위한 것이다.
단 이 때 tar 등을 이용하여 cold backup하는 대신에 disk 상에 cold
backup을 받아 시간을 절약할 수 있다. disk로의 backup이 가능한
이유는 export를 위한 time based recovery를 수행하기 위해 필요한
datafile이 SYSTEM, RBS, 삭제된 data를 포함한 user datafile
정도이기 때문이다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> shutdown immediate;
SVRMGR> exit
os>cp /oracle/oradata/*.ctl /oracle/backup/*.ctl
os>cp /oracle/oradata/redo*.log /oracle/backup/redo*.log
os>mv /oracle/oradata/system01.dbf /oracle/backup/system01.bak
os>mv /oracle/oradata/rbs01.dbf /oracle/backup/rbs01.bak
os>mv /oracle/oradata/tools01.dbf /oracle/backup/tools01.bak
redo log file이나 controlfile의 경우는 time based recovery시에도
필요하므로 cp를 받아두고, datafile의 경우는 mv를 이용하도록 한다.
위의 예에 제시된 file이름들은 해당 환경에 맞게 변경되어야 하며,
tar를 이용하여 tape에 옮겨도 관계는 없으나, 단 cold backup에
해당하는 모든 datafiles, redo log files, control files를 받아두어야
한다.
(2) 삭제한 data가 존재할 당시에 받아둔 backup에서 SYSTEM datafile, RBS
datafile, 그리고 삭제한 table이 들어있는 datafile만을 restore한다.
redo log files과 controlfiles은 현재 것을 그대로 이용한다.
(3) restore한 backup시점 이후의 archive file들을 archive log
destination에 위치시킨다.
full backup 이후의 archive file들을 일부 tape 장비 등에 backup을
받아두고 지운 상태라면 그러한 file을을 다시 원래 위치에 restore
하여, full backup받은 시점부터 복구하고자 하는 시점까지의
archive log file들이 모두 log archive destination에 존재하는지
확인한다.
(4) restore하지 않을 datafile, 즉 SYSTEM, RBS, 삭제된 data를 포함하
는 user datafile을 제외한 모든 datafile은 모두 offline drop시키
고, 데이타 삭제 이전 시점까지 time based로 recover를 수행한다.
이때 날짜와 시간 지정은 항상 아래 예와 같은 형식으로 지정한다.
만약 데이타를 삭제한 시간이후로 지정하게 되면 recovery후에도
여전히 data는 지워진 상태로 보여진다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> startup mount;
SVRMGR> alter database datafile '/oracle/oradata/temp01.dbf'
offline drop; (윗줄과 이어짐)
SVRMGR> alter database datafile '/oracle/oradata/userdata05.dbf'
offline drop; (윗줄과 이어짐)
... 이와 같이 resotre하지 않은 datafile을 모두 offline drop시킨다.
SVRMGR> set autorecovery on
SVRMGR> recover database until time '2001-01-30:21:00:00';
SVRMGR> alter database open resetlogs;
만약 이때, controlfile이 현재것이 존재하지 않아 datafile뿐 아니라,
controlfile도 과거것을 사용했다면, recovery command를 다음과 같이
지정하면 된다.
SVRMGR>recover database using backup controlfile until time
'2001-01-30:21:00:00'; (윗줄과 이어짐)
(5) 원하는 data가 제대로 조회되는지 확인한 후 필요한 table을 export한다.
예를 들어 scott user의 dept table을 복구하고자 한것이었다면 다음과
같이 export를 받는다.
os>exp scott/tiger file=dept.dmp tables=dept log=deptlog1
(6) time based로 recovery후 open한 db는 shutdown하여 없애고 (1)번에서
받아둔 현재 상태의 backup을 restore한다.
shutdown은 immediate나 abort 모두 가능하며, shutdown후 restore한
SYSTEM, RBS, user datafile모두 삭제하고, 사용하던 controlfiles,
redo log files도 모두 삭제한다.
그리고 (1)에서 mv나 cp로 (혹은 tar로) 옮겨놓은 모든 datafiles,
controlfiles, redo log files를 원래의 directory와 이름으로
위치시킨다. SYSTEM, RBS, user datafile도 반드시 (1)번 상태의
현재 상태 backup을 restore하여야 한다.
(7) db를 startup시킨 후 (5)에서 받은 export내용을 import시킨다.
os>imp scott/tiger file=dept.dmp tables=dept ignore=y commit=y
log=deptlog2 (윗줄과 이어짐)
(8) 원하는 data가 제대로 조회되는지 확인한다.
2. No archive mode 로 운영할 경우 복구 방법
archive mode 로 운영하지 않았을 경우에는, 삭제한 data를 export 받아
두었거나, 혹은 data가 삭제 전 받아둔 cold backup이 존재하는 경우
복구가 가능하다.
(1) export가 존재하는 경우
다음과 같이 import한다. scott user의 dept가 삭제된 경우를 예로 들었다.
os>imp scott/tiger file=dept.dmp tables=dept ignore=y commit=y log=log1
(2) cold backup이 존재하는 경우
다른 시스템에 사용가능한 oracle engine이 설치되어 있다면, 그곳을
이용하거나, 혹은 현재 database를 backup받아둔후 현재 시스템에
restore하여 export를 받아낼 수 있다.
(1) 현재의 모든 datafiles과 redo log files, datafiles을 다음과 같이
신중히 cold backup을 받아두도록 한다.
이것은 이후에 삭제한 data를 복구하여 export를 받은 후에 다시 현재
상태의 db로 되돌아오기 위한 것이다.
단 이 때 tar 등을 이용하여 cold backup하는 대신에 disk 상에 cold
backup을 받아 시간을 절약할 수 있다. disk로의 backup이 가능한
이유는 export를 위한 time based recovery를 수행하기 위해 필요한
datafile이 SYSTEM, RBS, 삭제된 data를 포함한 user datafile
정도이기 때문이다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> shutdown immediate;
SVRMGR> exit
os>mv /oracle/oradata/*.ctl /oracle/backup/*.ctl
os>mv /oracle/oradata/redo*.log /oracle/backup/redo*.log
os>mv /oracle/oradata/system01.dbf /oracle/backup/system01.bak
os>mv /oracle/oradata/rbs01.dbf /oracle/backup/rbs01.bak
os>mv /oracle/oradata/tools01.dbf /oracle/backup/tools01.bak
위의 예에 제시된 file이름들은 해당 환경에 맞게 변경되어야 하며,
tar를 이용하여 tape에 옮겨도 관계는 없으나, 단 cold backup에
해당하는 모든 datafiles, redo log files, control files를 받아두어야
한다.
(2) 삭제한 data가 존재할 당시에 받아둔 backup에서 SYSTEM datafile,
RBS datafile, 그리고 삭제한 table이 들어있는 datafile만을
restore한다.
backup당시의 redo log files과 controlfiles도 restore하여야 한다.
(3) restore하지 datafile, 즉 SYSTEM, RBS, 삭제된 data를 포함하는 user
datafile을 제외한 모든 datafile은 모두 offline drop시키고,
database를 open시킨다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> startup mount;
SVRMGR> alter database datafile '/oracle/oradata/temp01.dbf'
offline drop; (윗줄과 이어짐)
SVRMGR> alter database datafile '/oracle/oradata/userdata05.dbf'
offline drop; (윗줄과 이어짐)
... 이와 같이 resotre하지 않은 datafile을 모두 offline drop시킨다.
SVRMGR> alter database open;
(4) 원하는 data가 제대로 조회되는지 확인한 후 필요한 table을 export
한다.
예를 들어 scott user의 dept table을 복구하고자 한 것이었다면
다음과 같이 export를 받는다.
os>exp scott/tiger file=dept.dmp tables=dept log=deptlog1
(5) exprot받아낸 database는 shutdown하여 없애고 (1)번에서 받아둔
현재 상태의 backup을 restore한다.
shutdown은 immediate나 abort 모두 가능하며, shutdown후 restore한
SYSTEM, RBS, user datafile모두 삭제하고, 사용하던 controlfiles,
redo log files도 모두 삭제한다.
그리고 (1)에서 mv나 tar로 옮겨놓은 모든 datafiles, controlfiles,
redo log files를 원래의 directory와 이름으로 위치시킨다.
(6) db를 startup시킨 후 (4)에서 받은 export내용을 import시킨다.
os>imp scott/tiger file=dept.dmp tables=dept ignore=y commit=y
log=deptlog2 (윗줄과 이어짐)
(7) 원하는 data가 제대로 조회되는지 확인한다.

HT5312 I'm just trying to buy some things on the App Store and they ask me about those stupid Apple ID security questions I mean why do we still need to answer them if we forgot the answer do I wasted 15$ ****** for nothing I mean the money is still

Someone bought me a itunes gift card and it doesn't work cause this stupid Apple ID ask me to answer the questions I mean hello I'm the only one using it why do I need to answer these question?

I agree completely; email applications on the Mac lag (and I agree with the OP's frustration with responses as well).
I also have settled on Mail with Mail ActOn and MailTags; this functionality should be incorporated into the OS. I actually like using Outlook in Win 7 better; it's super easy to connect files, contacts, email and other stuff right from one application. And Win 7 has better preview and tagging built in, better than QuickLook. On the server side we desparately need gmail to use tags, but I don't see that happening. I still prefer the labeling scheme it has over Apple's mail, however. But I also find that it confuses many users (labels vs folders).
There are also other applications that integrate email functionality, like SOHO Organizer, or Contactizer. Good, but not the email holy grail.
I'd like to see communications built into the Finder or system, which badly needs an overhaul. It hasn't changed much since the 90's and shows it. Communication, whether it be email, tweets, social media posts, sharing, etc, is such an integral function of all work you do on a computer it should be better, um, integrated into all applications. You should be able to send data from any application to others in a variety of formats without having to go into an email application. Sure, you can now do this to a certain extent with either built-in menu items or services, but it's clunky. For example, when you write something you can either "save" and write to disk somewhere, or "export" in a different format, or maybe "email." All of those choices should at least be part of one dialog; it's just as likely you want to email, post, share or tweet what you just wrote, so just having a "save" dialog is way outmoded.
So, yeah, somebody get on this.
