Export in user mode?

Questions:
1. I need to export all object of auser named "target" if I make the following command line the data in the tables (rows) will be exported?
"exp SYS/password@instance AS SYSDBA FILE = export_target.dmp LOG=export_target.log OWNER=target"
2. If I want to export it in a target schema named "target", have I to specify TOUSER parameter or just import it, will import in a schema named target?
3. This command, from where I have to execute it (SQL Plus or Prompt)? where will put the file ".dmp" in the export.
Thanks in advance.

1. Do not export with sys account. ;-)
Consider using SYSTEM instead.
BTW, the exp command seems to be ok
2. Export is exporting. The Fromuser/toUser has sense only during import.
3. Run this at the prompt. The file will be generated in current folder.
4 and most important : make the tests by yourself !!!! you'll learn more and faster...
You can try those 3 points alone, without this forum... ;-)

Export/import (user mode)

can you help me please,
1- I exported the SCOTT schema (user mode):
exp scott/tiger FILE=D:\scott.dat LOG=D:\scott_exp.log OWNER=SCOTT
then I imported to new created before schema SCOTT_COPY:
imp scott_copy/tiger FILE=D:\scott.dat LOG=D:\scott_imp.log
fromuser=scott
touser=scott_copy
I got in scott_copy only tables from scott (all existed types were not successful imported) WHY only tables (see log)!!.
2- What is the best way to export user and import it with all (objects and privilegs granted to origin user).
thanks
jamil

EXPORT Problem. when i choose USER mode, it is exporting full database

Dear OTN Members,
we have a system ORacle 8i, 8.1.3 database, we created a user with DBA role, when we want to export data for a perticular user, after giving USER MODE Option, it is doing full database export including sys, system etc.
what is the reason?
Thanks in advance

Any ideas please,
Still im looking for this solution. I have a " user" with DBS role, we are trying to export only this user, it is coming up to type of mode like

we are choosing user mode, but all the time it si taking Entire databse, including, Systtem and other users eetc.
im struggling since 20 days. no success. Please

How to mount USB & CDROM drives from single user mode - Solaris boot disk?

Hi All,
I need to carry out ufsrestore on a single newly replaced system disk (no redundancy / mirroring) from either USB or CDROM drives from the following steps:
( i ) GRUB => e, e, cdrom –s, Enter, b (boot from Solaris 10 x86 media).
( ii ) Choose menu 1 for Install Solaris Interactive Mode to reach single user mode.Below are the commands that I have tried in single user mode without success:
mount –r –F pcfs /dev/dsk/c1t0d0p0 /cdrom (after unmount Solaris CD)
mount: /dev/dsk/c1t0d0p0 is not a DOS filesystem.
svcadm –v enable smserver
svcadm: Pattern ‘smserver’ doesn’t match any instances
svcadm enable autofs
svcadm: Pattern ‘autofs’ doesn’t match any instances
devfsadm
devfsadm: mkdir failed for /dev 0s1ed: Read-only file system
mkdir /mnt
mkdir: Failed to make directory “/mnt”; Read-only file systemPart of the problem is due to the current READ ONLY filesystems which does not allow the creation of mount point such as /mnt.
I have been able to create both / root (/dev/dsk/c1t0d0s0) and /export/home (/dev/dsk/c1t0d0s0) filesystems with newfs that are awaiting for restore using ufsrestore.
The only option I am left with is to attach a secondary disk to install Solaris 10 on either of them before bring the system to multi-user mode so that service such as volmgt, autofs, volfs are available to access USB & CDROM drives.
Any suggestion on how to resolve this issue?
Many thanks,
Jack

Hi JKGN,
Is the directory a located under the root filesystem. ie /a? Are there any other mount point for say USB drive as well? I am not in a position to try it out right now but will get back
to you soon on whether /a exist or not.
Btw, the last thing I managed to do on this system at the time was added a secondary 1TB internal disk with the intention to restore both / and /export/home data onto this disk while
making use of all the disk device management services such as the following services only available in a fully installed Solaris system (both single & multi-user modes) installed on the
primary disk:
# svcs smserver
STATE          STIME    FMRI

# svcs autofs

As a result, I am left with no option but the need to rebuild this system with only a single primary disk while in single user mode. However, the single user mode that I am in is the
one from Solaris installation disk with restrictive (_cannot create folder for mount point or running disk management utilities_) capability such as those services just covered, compared to one from a completed Solaris installation system with full access to all filesystems and utilities / commands in general.
I would very much value your assistance on how to mount both CD & USB in this restrictive limited Read Only OS (assume that it is running from memory) in order to get complete access to
the blank primary disk so that full restore with ufsrestore could take place.
Thanks in advance,
Jack

TABLESPACE - single user mode

Is it possible take a single tablespace in "single-user mode" ? In this way, only a single user ( a dba ) could apply transactions to the table in the tablespace, other user could not. This would be very useful for recovery. In case of a dropped table, I could take the tablespace unavailable to users, restore a table with the "IMP" oracle utility, use the logminer utility to identify all transaction applied to the table between the last exp and the drop of the table, apply transactions and take the tablespace available to users.
Thanks a lot for answers.

You can take the tablespace offline but then you can't import the table. In 10g to recover from accidentaly dropped table simple use flashback option no need to do any kind of recovery. Other option would be to imp the table from last export the rename it to something else and then apply all the transactions taken from logminer (a very tedious process) and then rename the table back to original one. If you using archivelog mode then you can also consider TSPITR.

User Mode Linux -- Compiling problem

Hi,
I want to run the user mode linux for linux-2.6.17.6. When I try to compile the user mode linux I get this error:
In file included from arch/um/include/os.h:13,
from arch/um/drivers/fd.c:14:
arch/um/include/kern_util.h:9:27: error: linux/threads.h: No such file or directory
make[1]: *** [arch/um/drivers/fd.o] Error 1
make: *** [arch/um/drivers] Error 2
I was looking up a lot of time in google.
My steps to compile it is:
export ARCH=um
make defconfig
make
If you have any suggestion, let me know.
Bye.

Using that option the kernel compiles smoothly. The problem here, is that I am not getting the kernel that I want. I am just building a normal kernel.
Any suggestion, let me know
Luis.

How to restrict the all access ? Single user mode....

I am doing export/import of schema objects from Windows to Oracle. How to make sure when I do the export in the migration database no one else is modifying the data. Is there any single user mode so that I can be sure of only one connection while exporting?
Oracle 10g R2 on Windows Server.
Thank you,
Smith

Perhaps you are not familiar with the concept of multi-version read consistency.
No one can see that which is not committed and reads can never be blocked.
If you want a system where no one can see things kill their sessions and do a STARTUP RESTRICT.

Data back up from Single User Mode

Hello,
I have a problem with my 700 MHz iBook, dual USB, with OS X 10.3.9.
Unfortunately the OS doesn't start up because of "overlapped extent allocation" problem...
I would like to re-install the complete OS but before doing it, I would like to back up some directories.
Is it possible to save some data, by connecting an Ipod or some sort of external peripheral, from the Single User mode?
If yes, how can I do it?
Thank you in advance from your kind support.

Before giving up the ghost check out these:
http://docs.info.apple.com/article.html?artnum=25770.
Manually fix Overlapped Extent Allocation Errors without Disk Warrior
Overlapped overlapped extent allocation errors can be the bane of any Mac user's existence. Often, these errors go unnoticed until the problem becomes visible: your Mac might refuse to boot, crash unexpected, or worse, critical data might disappear from the Finder. Disk Utility can detect, but not fix overlapped extent allocation errors, and certain third-party utilities, such as Alsoft Diskwarrior, can fix them, but generally without reporting the consequences.
Overlapped extent allocation error occur when the file system thinks that two files are occupying the same area on the hard disk, hence overlapping on the same "inode," which is the structure which holds the location of the data blocks the file occupies, and also file permissions and flags.
Clearing the "overlapped" or "overallocated" extent allocation essentially means that you'll have to lose some data, because the only way to remove the overlap is to delete the file that's occupying the inode. So, if you suspect, or find out, that the guilty file is a critical system file that resides in one of the hidden system directories such as /etc /var /usr/ or visible system directories such as /System or /Library, and you don't want to reinstall the whole OS (which might not fix the overlapped extent allocation anyway), it's good to have another disk available to copy the files back to your original disk if necessary: a second bootable hard drive or a firewire drive connected to your Mac when you remove the misbehaving file. Just make sure that when you copy the file back to your boot disk that the permissions are correct, so it's best to use the "ditto" command, so that all sticky bits, flags, and permissions are preserved.
In case you didn't know, you don't have to boot from an install CD in order to check for overlapped extent allocations. All you need to do is restart your Mac, while holding down command + S to boot in "single-user mode."
At the command prompt that appears, type:
$ fsck -fy
If you have an overlapped extent allocation, you'll see:
"Overlapped Extent Allocation" (File 123456d)
No matter how many times you run fsck -fy, you'll never be rid of the error.
So, simply issue the following command:
find / -inum 123456 -print
Note the "d" was dropped, or any extra letter that appears after the inode number.
The find will return a file name that matches with the inode number, and the path to that file. If you remove the file then the fsck will not return this error next time you run it.
However, before you can delete the file(s) in single-user mode, you'll need to mount the file system. Type:
$ mount -uw /
When done, issue the "sync" command, and that will flush the write cache so that all pending writes are written from memory to the disk. Also, since most OS X 10.3 Macs use the HFS+ Journaled file system, it might be a good idea to disable the journal before booting into single-user mode by typing:
$ sudo diskutil disableJournal /
then re-enable it when done fixing the overlapped extents and rebooting normally:
$ sudo diskutil enableJournal /

If you own Disk Warrior then it should be able to repair a drive with overlapped extents.
There are two backup utilities included in Unix - psync and rsync. You will find them in the /usr/bin/ directory. For documentation simply enter: man psync or man rsync. In order to write data while in single-user mode you need to issue the command: /sbin/mount/ -uw / (Note: there is a "space" between the "uw" and the "/".) To mount an external drive you will need to provide the mountpoint for it in place of the "/", e.g., "/Volumes/volname") without the quotes.

How do i repair my hard drive in single user mode when disk is full?

Hi there Apple Community!
I have an old Macbook Pro 17" with an upgraded 500GB harddrive and 4GB memory. I'm running Mac OSX Lion.
Was hoping you could help me out. THis is the situation:
Long story short I spilt wine on my macbook and the screen went a bit blobby. Switched it off for a few days, removed the battery etc. etc. Opened it up cleaned out as much of the wine as possible, but unfortunately some of it came in behind the LCD, so now the screen has a nice red stain. Obviously I'm not going to try to clean that out of the LCD.
My Macbook Pro still worked for a few days after that, but then my harddrive gave up. I booted in the Recovery HD menu, verified the drive and I got the error "Keys out of order - This disk needs to be repaired, click Repair Disk." I attempted to repair the disk but got the error "Keys out of order - Disk Full Error - The volume could not be repaired".
Unfortnately of this 500GB I only have about 7GB free on it, as I have a huge iPhoto and iTunes library. I did make a TIme Machine backup of my user directory, but not the system files. I don't really want to do a clean install because:
1) I'm paranoid that there's something I did not fully back up
2) I don't want to have to download the whole Mac OSX Lion again. I should have made a USB bootable backup when I had the chance. I don't have access to a broadband connection.
What I feel are my viable options, are as follows:
1) I did buy a replacement internal 500GB harddrive, so I can probably try to make an image of the hard drive to this new drive, but not sure how. I believe it's through the Disk Utility with the "New Image" option but not sure how to go from there.
2) Start up in Single User Mode and delete some unnecessary files and re-attempt to run the fschk -fy utility again (I tried this earlier and got the same Disk Full Error). - the problem with this is, I'm not familiar with the command line and have no clue how to delete files. I don't know my way around Unix.
3) I can also probably attempt to make a Ghost Image or Acronis Image of the failed drive to this new drive, but not sure if Norton Ghost or Acronis True Image will be able to read this HFS drive - I believe it's possible as it's a simple hard drive clone.
If you can guide me in the best option - probably there is a better solution than my proposed ones above, I appreciate any feedback and comments you might have!

hi Baltwo,
So I ended up copying my user folder to another harddrive. I managed to download the whole osx lion again, reinstalled, and recovered my home folder using this discussion:

I've done an Apple Software Update but it didn't find an update for iPhoto.
One thing to note is, this library was originally created on iLife 08, upgraded to '09 and it stayed on that version. It hasn't een upgraded to iLife '11. It worked fine on my previous install of OSX Lion. How do I recover the library without upgrading to '11 ?

Kernel panic on MacPro in Single-User mode after memtest.

I've had about 7 kernel panics in about 7 days on a new MacPro. 2 gigs of RAM (Apple Installed). Fresh install of OSX (no user import). While going through the troubleshooting process I ran memtest in single user mode. Ran it all night no errors.
So in the morning I typed ctrl-c and then exit (i think)... it seemed to start the process of booting and I got another kernal panic. I've actually done this three times now.
I checked panic.log and all the error messages but 1 were the same. Including the ones I got in single-user mode (copied below).
Should I be able to gracefully exit out of single-user mode without a kernel panic?
Does this point to a RAM error even though memtest and AHD for that matter ran all night without finding anything?
I'm all set to try again (taking careful notes this time) to see if I can reproduce but I was hoping for some feedback first.
Thanks,
Craig

Welcome to Apple Discussions!
Yes, your memory or memory slot, or memory seating is bad or off. "Uncorrectable Fbd memory error detected. ferr = 20000000 , nerr == 00000000, fErrFat = 20000000 nErrFat == 00000000"
Clearly a memory related issue. It may also be that memtest doesn't know how to diagnose the new kind of memory and is reporting that back to the logs. Take it in to a service center to have all the boards replaced to make sure the issue isn't reproduceable with new memory. If it is, then I'd consider the slots on the logicboard a problem.

I changed my wheel group properties to no access at top disk level. I messed up, how can I change back in single user mode "command s" as I am now in Thailand and not able to access startup disks?

I messed up, I changed my "Wheel group" properties to No Access ( or something other than the default) at the top level of my startup disk "Macintosh HD".   Now my computer won't start up, I just get the spinning wheel of death.    I also am in Thailand right now, so I cannot go to a Genius at an apple store, nor do I have startup disks available.
So I was hoping there was a way to change back the properties of my disk (Volume) in single user mode (via Command +s) during startup, i.e. can I do a chmod command on the Macintosh HD listing under the Volume Directory.    Or where do i fix this?   Is it fixable without startup disks, etc...
THANKS FOR ANY HELP!!!!
If you could also please let me know you have an answer, I WOULD REALLY APPRECIATE IT!!!
thanks so much

Thomas,
Thanks for the info on command-R, didn't know about that!!!
Yes I changed the sharing "Wheel Group" permissions on my hard drive via Get Info.    But that's all I did.    And then most of the apps wouldn't respond with anything.    So not knowing I did something stupid, I decided to re-boot, and then nothing but the Wheel of Death at startup.
I was trying to limit access to my computer on this network, changed my public folder settings, and then I thought why not the whole hard drive, but at that time I had no idea what the "Wheel Group" was... so I shouldn't have touched it, BUT IT DID ...... argggggg....
I managed to go to an internet cafe & research the problem yesterday.    I used the command +s single mode to get in, and then did the necessary steps to mount the drive so I could make changes.   I basically did this:
Boot into single-user mode (boot while holding down CMD-S)
Follow the on-screen instructions to mount the file system as read-write (a fsck command followed by a mount command)
Type the following: "chmod o+r /" followed by "chmod o+x /"
Type "exit" to leave single user mode and complete the boot sequence.
I found it at this link http://forums.macrumors.com/showthread.php?t=416180
It worked... thank God!!!   Well so far so good.
I was going to try my own fix by chmod on the Hard drive listed under Volumes directory, but that doesn't seem to match the info under Get Info Window.    So I just used the fix above.    I probably should now go and do "Disk Utility - repair permissions", however I am a little gun shy right now, so I will probably wait until I am back in the States so I can go to an Apple store if it messes up.   Right now I'm following the "if it ain't broke, don't fix it" MOTTO...
So Thomas I just wanted to say THANKS for replying so quickly, and I really appreciate your help!!!
(yes I know I shouldn't have used my email addresses, but I WAS DESPERATE, but that's still no excuse)
Hopefully maybe this thread will help someone else out in the future....
Okay, thanks again!

Why can't I enter single user mode on my Mac Mini for an admin password reset?

Hi,
I recently created a new user account for my mac and deleted the old one, not realising that this was the only account with admin priveleges. As such, I no longer have access to administrator priveleges, and cannot grant them to my new user account.
I have tried to boot in single user mode and recovery mode but neither command results in any reaction on the part of my computer.
This thread follows on from a previous, unrelated disscussion:
BDAqua: If you hold alt key at bootup do you see a lock in the middle?
Yenots: No...what does this mean?
BDAqua: If it did, it would mean Firmware Password Protection was enabled, which prevents booting in other modes, so that's not the problem, are you using a wired Mac KB, or Windows KB?
Yenots: I'm using an 'Apple Keyboard with Numeric Keypad' [ http://store.apple.com/uk/product/MB110B/B/apple-keyboard-with-numeric-keypad-br itish ]
If you find me here BDAqua, hit me with your knowledge!
Any other contributions are welcome and, now we're under the right heading, will hopefully help other users who have encountered this problem.
Thanks, Cristo

Hi,
Thanks for the link to MacPilot, and the sexy screenshot. I found an archived version for 10.4 on the koingosw website. That solves getting into single user/safe mode. Though I'd be interested to see whether sudo nvram boot-args="-s" will result in single user boot.
As for creating administrator priveleges for my new user account, I've found a method which looks good:
     \single user mode\
     cmd-s
     \mount drive\
     mount -uw
     \open 'directory access'\
     lauchctl load /System/Library/LaunchDaemons/com.apple.opendirectory.plist
     \list users\
     ls /Users
     \change password\
     dscl . passwd /Users/<username> <password>
I think that this method intends that if I change the root users password I'll be changing the administrator password (as root is the only user with administrator priveleges), and subsequently be able to change my new user accounts priveleges using 'netinfomanager'. But I'm not 100%. Could you give me your opinion on this?
Furthermore, three keys 'L' 'O' and '(' aren't working on my keyboard, which means I can't try this until I find an intact keyboard to borrow. I was thinking maybe a mod version of the above instructions would work in terminal using sudo, so I could use the keyboard viewer to type the missing characters. If you have any ideas on constructing such a mod I would be interested to hear them.
Otherwise, Thank You for your help BDAqua! And enjoy your summer wherever you are.

Error while exporting one user

Hi all,
While Exporting on user in Oracle 9.2.0.1 i am getting this error:
EXP-000008 ORACLE error 600 encountered.
ORA-00600: internal error code,arguments: [12811], [41965],[]
ORA-06512: at "SYS.DBMS_EXPORT_EXTENSION", line 248
ORA-06512 : at line 1
EXP-00000: Export terminated unsuccssfully
But this error message comes only for one user not for others.
Please suggest the solution for this problem.
Thanks in advance,
Vipin

This is a known 9i bug,
Bug# 2443896, it is documented here --> Metalink Note 2443896.8
OERI:[12811] from concurrent SELECT and DDL (DROP) with SQL_TRACE=TRUE
This bug was fixed in 9.2.0.2.0. I strongly suggest you to apply tha last patchset available. Since the terminal patchset available for 9iR2 is 9.2.0.8.0 you will prevent to hit known bugs up to this version.
This is just my personal recommendation, but Oracle Support Services has the last word on this issue.

Single User Mode : Read Only Filesystem

I can't edit files in single user mode as Root. When I try to edit them I get a msg saying "Read Only Filesystem".
I have tried chmod with no evial. I want to change my .profile as root so cls='clear'.
Any ideas?
Also when I try to login to my account in single user mode it says that account does not exist. However I'm in that accunt right now!
Thank You.

When you boot up into single user mode, there is a single recognized user -- root. That's why they call it single-user mode and not multi-user mode.
When you boot up into single user mode, the disk mounts as read-only. You have to make it writeable in order to do anything to it. I forget the actual command but it displays on the monitor nearby where it gives the "fsck" command syntax when you first boot into it. It's something like "mount -uw /" or something to that effect. It is saying to mount the root drive ("/") with user write privileges.
Then just "pico /Users/Mephux/.profile" (although I profess that I don't understand why you have to edit this file as root).
