The base backup.

Hello

Can we take full backup/dump DB and ignore a few sets on the data in the table while taking a dump.

Scenario is similar, suppose I have a database 'test' with some 20 paintings and all having some 1,000 records.
While I take export, can I take the table structure for all 20 tables but records for only 15 tables. I want to export 5 remaining tables with 0 records.

Physically I can't remove records from the tables prior to export.

Thank you

As I said on the thread SQL and PL/SQL,
If you use RMAN, no - you can only chose to back up specific storage space or the whole base
If you use export datapump (not really a "backup") then Yes, the QUERY parameter lets you specify a query for each table data filter. To export all the tables owned by davidp, but only the structure, not the rows, or tables "t" and "u":

expdp schemas=davidp query=('davidp.t:where 1=0','davidp.u:where 1=0')

You can also use the QUERY parameter to import, if the export included lines that you do not want to import.
Kind regards
David

    Hello!

    I am trying to restore to a different machine with a different database. I created the database with the same SID, but the computer name is different from the other.

    You may need to restore the controfile of these backups first before you can restore files.

    in this case to do that:

    Start the db2 as nomount with your pfile file instance

    then
    RMAN target /;

    RMAN > RESTORE CONTROLFILE 'filename '; -"the file name is backups that you have copied the disk."

    can do the

  • A key using self-powered USB causes the base station go "off-line".

    I found that by using a USB drive self-powered, as the WD My Passport, without a USB powered, hub attached to the base of the station USB port has caused the base station go "off-line". In fact, using a powered hub does not always remedy the situation, but it is more reproducible without one.

    This is true for the AirPort Extreme and Time Capsule 802.11ac. The problem does not occur immediately, but it may happen over several days. The symptom is that the player is no longer lies in the Finder, or the base station appears in AirPort Utility.

    My question is if others have had the same results? ... and did you find permanent solutions?

    USB key "seems" less reliable on the airports of AC model than on previous versions.

    I tend to not use USB attached to routers because I think it's convenient mediocre and poor speeds. But I tested with previous models, and it seems ok...

    KT those a few posts here a me trial there. These are not self powered readers... who I have long recommended people avoid the use (without a powered hub)...

    Re: External backup drive down regularly

    In fact, the wire is different from what I remember... Age don't you know.

    But I did the test on an AC TC. The result has been very reliable. He did not cause the TC to close... but I lost the connection of the USB almost every day... except for a trial where I kept the USB drive mounted in the Finder... so that the USB drive wouldn't turn it down. He then worked for a few weeks... until what the noise of rotation of disk (sitting next to me) drove me crazy... as soon as he was mounted is more, he would pass the same existence as before.

    The previous model TC was barely big enough for the internal use of the power supply units. So powered car running disc was impossible.

    Provide EI (GEN 1-5) at 1. 8A and 12v was adequate, but the standard USB port is estimated at 500 my wrong to manage disks free power.

    You would certainly think AC 12v 5A power supply models would have a lot of power. Yet, power problems are a major problem still. Supply is extremely sensitive and stop easily for reasons I'm still to understand.

    Where the long threads on power issues to the AE.

    Now, I'm going to speculate... I think that SOME problems are associated with power.

    What is the USB port side in airports of AC? Is it still 500ma? Apple never seem to give easy to find info on these details.

    Do you know? I haven't measured it, but I can try timing the time it takes to charge a phone.  Assuming that it will immediately trigger.

    Then he will have problems with a self-powered drive. Even if the drive has less energy than quotes, current during starting is much higher. The restriction of the power on the USB port is managed by a self regulator recovery... Once you triggered it, you must stop the power... then reboot the machine to restore power.

    Then, I also did the test with hub powered... and like your results... It was better. Longer time between the drive disappears from the network. But it was not enough to stop it.

    There is another interesting effect using self-powered hubs... I discovered this on a computer running Mac OS lets say! The computer would not start with a powered hub connected to the front USB. Hubs self-powered cheap, showing a defect in their design. They can refer to the USB port. In this computer, it was enough to stumble on the good power circuit and prevent the supply, commissioning... As long as the computer is running, everything was fine... but if I turned off it would not start. I finally woke up I had to exit the USB every time. At one point, I made a "special" Cup USB cable 5v line so the hub can stay connected. You can probably just to isolate the 5v of contact in the USB. Regardless of the configuration of power USB in the AE or TC is as you can assume she's sensitive enough... and at any time when the 5V on USB hub exceeds the 5V in AE it could trigger.

    The symptom is that the player is no longer lies in the Finder, or the base station appears in AirPort Utility.

  • Makes 32-bit is better for the battery backup?

    Original title: I got windows 7 32-bit professional to give above 4 hrs battery backup. And now I have installed the 64-bit but backup is about 3 hours. Makes 32-bit is better for the battery backup?

    Don't really know why it happened then... Should I switch to 32 bit? What is the best?

    There should be no significant difference in energy between 32-bit and 64-bit, you will need to check your settings of power and performance.

    As for which is better, it depends on two basic points. 1 do you really use all that needs or benefits of 64 bit, not a lot of programs don't. Second, how much memory is installed. 32 bit is limited to 4 GB native but about 3.2 GB of technical limit. However, 64-bit requires more memory base so in fact will help only if you have more than 4 GB

  • Rescue and recovery of backup fails: current drive does not match the previous backup

    I have just rebuild my T60p with a new hard drive for the recovery of Lenovo CD via the rescue and recovery CD. Once the system restore is complete and the laptop running, I took a full backup using Rescue and Recovery. This backup is the C:\ drive which was the only drive I had and was on a USB hard drive.

    In recent days I have the C:\ split in two, giving me a new D: drive, patched all system software, added my own data, and obtained the machine configuration as I want. I've also trashed the R & R hidden partition so I could make a bigger drive D:\ and created my own bootable CD R & R for future use - not that it makes a difference.

    Now, I want to take a second backup with the Rescue and Recovery tool. Naturally I want to back up the disks C:\ and D:\, but the backup fails saying: -.

    "The last backup of this system include the following drive letters: C: .

    Your system is now back up these drive letters: C: d:

    Please define drive letters, as they were before and Christine backup. You may need to exclude partitions created since the last backup. »

    Is there anyway that I can make a backup of disks C:\ so my D:\?

    The only option I see is to delete my previuos backup and I don't want to do because it can be useful in the future if I still want to restore my system to original state manufactured.

    Suggestions anyone?

    Thanks, Iain

    Given that you have saved on an external USB disk your backup will be saved in a

    the folder named RRbackups.  If you rename this file I - think - R & R going to think

    you do not have any backups, so the next backup will be a 'base '. If you

    never have to restore the original of your 'base' backup, rename the folders should allow.

  • find the right backup of cloning using up the time option

    Hello

    I'm trying to create a script to find out what files to backup (backup rman, rman backup control file and archivelogs) are needed to create a clone of production data base lets say for 1 month ago or two weeks ago.

    My backups are marked, performed on the disk, but a night job takes the disk backup files and moves them to tape.
    So, before I can restore correct correct tape files, I need to know what files to backup should I restore a band.

    I could start the clone and she'll tell me it cannot find the files of backup that is named xxx, yyy and it will eventually error and output, but I find the files.
    The idea is to find the files before the script (script clone) could not find the right files.

    I tried to use the v$ element_sauvegarde, v$ backup_files equivalent rc_ view (s) and tried to join them, but I couldn't find the join columns. I tried stamp column. This gives me some information so I can find the files, but I need to know the approximate duration of the backup.

    So my question is: how RMAN queries it sees? (v$ backup %) I couldn't find a link to foreign key between tables.
    Here is the result of what I managed to find, but I have to give the approximation of 1 hour (1 hour before NMR files have been generated and 1 h after) so I could find the controlfile files and the archivelogs rman backup files.

    I'm trying to set up an Airport base station and stuck because I have the following message is displayed, but no idea how do what he asks...

    Status is showing as Double NAT and then asking me to move on to the base station in bridge DHCP/NAT mode.

    But where do I do this?

    Thank you

    It can be difficult to get the router to bridge sometimes... but if all goes well... Click on the airport icon in airport utility and then click on edit.

    Go to the network tab and change DHCP and NAT to bridge.

    Click Update at the bottom of the page... Then, everything should be good.

    If you are having problems follow these steps.

    Reset factory airport and then do a manual installation. I recommend that you connect with ethernet which is much more reliable, but your MBPr is not the most important network port that exists... Although there is a bolt of lightning at low cost for the ethernet card.

    A few days ago, I backed up my iPhone 6 before heading to Verizon to update the iPhone 7 (128 GB). At this point, all my photos are in normal chronological order. Once I got the new phone, I plugged into my MacBook and put in place since the last backup, and my photos were so totally out of order and in all directions in my camera roll.

    HI - we are a company with about 350 users of iPhone and iPad.  I put this in the iCloud in the community section, but I've seen other users have the same problem in this section, so I thought I would add here.

    In order to stop users add their own e-mail accounts on the iPhone that lock us the device through restrictions - deactivation of the accounts section.  It stops and then access the iTunes settings.  In the test of iOS 10.0.1, we have one of the devices (a 16 GB 5 s, who had been a backup at 7:20 that morning), improved 9.3.2 that went well with no obvious problems, then, after a few days to leave the handset to the function, we have lifted the restriction and the backup on iCloud to find any backup not occurred since the upgrade and a message 'some files were not available during the last. backup"in its place.

    If all our staff upgrade their phones (we gave says not yet) then the backups look like they stop.  It is easy to fix, as a manual backup, will complete the process, but you have to remove the restriction to do this.

    We tested on iPhone 5, 5 s, air iPad iOS 8 to 9.3.5 and all have this problem.
