• TDE - Transparent data encryption

  Hi all

  I have an EMP table with encrypted column CREDIT_CARD_NO.

  This encrypted table resides on PROD.

  Then I export using the EXP of EMP table that resides on DEV server and it is not encrypted.

  Can I import (imp) this dumpfile prod that is encrypted?

  I tried, but I got error

  H/h = emp file tables IMP = expdat.dmp ignore = yes

  IMP-00058: ORACLE error 1031

  ORA-01031: insufficient privileges

  I have already given HR a dba role privileges EXP/IMP.

  Correction: I have only granted privileges DPPUMP, which is the equivalent for EXP/IMP?

  Thank you very much

  Hello

  My knowledge of database vault is that theoretical - I've never really used. As far as I know that same SYS cannot bypass the security of vault database - that explain the error you get with SYS. I think the error with HR is misleading (unless there no DBA) - try to remove the fromuser/touser completely you have not needed - does work?

  Users who access was granted to the Kingdom of database vault? You can import one of these users (temporarily give them s/n?)

  Can give you Kingdom access to HR through the vault db gui tool (see the example here for 12 c - Although it should be the same in previous versions http://docs.oracle.com/cd/E16655_01/server.121/e17609/tdpsg_dv.htm)

  You might have more luck this announcement in a database vault forum - I guess there's a?

  See you soon,.

• Windows 7 pro 64. The desktop icons won't stay where I put them. After a reboot, the desktop icons are always rearranged.

  I've set up my office while I have the following icons down the left side of the top in the following order: computer, network, System (C), (D) options, reader of DVD (E), trash.

  Whenever I restart my computer, the icons are rearranged as: computer, network, trash, reader of DVD (E), options (D), System (C).

  I don't want to add all the new icons on the desktop, because I know they won't stay where I put them. When I was using XP it would happen only when I changed resolution but with Win 7, it happens every time that I reboot.

  Reorganization of auto desk is off, snap to grid is turned off, sort by has verified. I use two monitors. All the gadgets that I have in my hand right 2ndary monitor are stay in place very well. The icons gives me the problem are on the left side of the left main screen.

  I made an image of my hard drive just after the installation of windows 7 and before to install the drivers of manufacturers and updates of windows.

  Today, I restored this image, reinstalled the drivers from manufacturers and made the updates of windows. The problem seems to have disappeared now.

  I am re-imaging my hard drive after you install the complete driver/updating. I hope I don't need to use it, but I will if I have to. I still don't know what caused it in the first place, but at least now I have an option of fast food if it happens again. I'll recreate the image on the hard drive after all major software install from that time, I have two images. A fundamental right after pilot installations and one after each installation of software.

• Transparent data encryption and Performance

  We started a project to encrypt our SAP database using the transparent data encryption.  The project is currently mandated by corporate policy, so there is not much choice involved.  The indications are:

  The server O/s: HP - UX 11.31

  CPU: HP Itanium

  Oracle Version: 11.2.0.3 (64-bit)

  DB Dimensions: Approx. 5 TB

  Core SAP: 7.x

  Our leadership is very concerned about the impact on performance.  If you have encrypted your database, SAP or not, I am very interested in hearing if you the performance of your server data after encryption.  Good news, bad news, either.

  TIA,

  Mike

  Dear Mike,

  I can give you a few comments based on direct experience, since we recently migrated from an unencrypted Oracle (11g Enterprise Edition Release 11.2.0.3.0) server to a new server with encryption TDE (same version db).

  Our application is a warehouse of data with massive volumes of data (terabytes) and a few very large tables.

  After having migrated to the new server, which was much more powerful than the former, we were surprised to discover that the performance was much worse (about two times slower, on average, measured on our typical user queries).

  A study on the causes of degradation in performance shows that transparent data encryption are the source of the problem, causing a saturation of the individual CPU (do not look at the aggregate average load on the CPU, which is misleading).

  Basically, we have been deceived by the official Oracle documentation that estimates the impact on the performance of the transparent data encryption in the order of 5 to 8%. Further investigation showed that this low impact may be true of operations that involve a small amount of data. With the full picture of the analyses on large tables however, the truth is that the performance may be (5 - 10 times) slower order that without transparent encryption of data.

  If you want more information, take a look at this excellent article (in two parts):

• Develop the encryption Transparent data with Oracle 10 g XE

  Currently I develop an application that will require encrypted in some tables columns, I will recommended to the customer buying an Oracle database for the application and that you have installed Oracle 10 g XE to begin development, I found that I can't create tables with columns TDE tho I can't create a portfolio. I searched the forums and found that a portfolio manager is not available with Oracle XE.
  
  My plan was to develop the application and then provide scripts for creating the DBA of the customer so that they can create data tables in their Oracle database... Can I develop the application without transparent data encryption and then say s/n, which must be implemented in the version of the application? The application needs to know the password of portfolio/TDE to encrypt/decrypt the columns!
  
  Any ideas how I could go on the development of the customer Oracle XE database without access to CDW?

  The T in TDE is transparent, so that your application should need not even be aware that all columns or storage are encrypted. Transparent data encryption are generally implemented in systems that were never designed to encrypt data, so in theory it should be 'perfectly safe' to develop not encrypted and have the client encrypt the columns during installation.

  Of course, when marketing people start talking about things that are 'perfectly safe', it is always a sign of coming danger. Although I have never heard of a case where encrypt a column caused a problem for an application, I would be very doubtful to the development in an environment different from that of production. This includes the exact version of the database (I guess that the customer has installed the last patchsets, so they run 10.2.0.4, for example) as well as editing. If you decide to rely on the fact that everything should go smoothly when you promote to a different version of a different edition of the database with a different schema definition, even if it would normally, you virtually guarantee that you will end up with a problem that will be difficult to solve.

  In your case, I would use XE to the development. It would be much safer to develop against the personal edition. It's not free, but it's the database licensed Enterprise edition to run on developer machines. It is not free, but it is much less than an enterprise edition license.

• How to reset the Master encryption key in the encryption Transparent data...

  Hello

  I use Transparent data encryption in Oracle Database 11g Release 2.

  After having specified an Oracle Wallet location in the sqlnet.ora file as shown below:

  
  

  ENCRYPTION_WALLET_LOCATION =

  (SOURCE =

  (METHOD = FILE)

  (METHOD_DATA =

  (DIRECTORY = D:\Oracle\enc\admin\tde\wallet)

  )

  )

  Created the master encryption key using the statement

  SQL > ALTER the ENCRYPTION KEY SET of SYSTEM IDENTIFIED BY 'Abc123def456 ';

  Modified system.

  When I reset the master Encryption Key by using the statement get an error as shown below:

  
  SQL > ALTER the ENCRYPTION KEY SET of SYSTEM IDENTIFIED BY 'Easy2rem ';

  ERROR on line 1:

  ORA-28353: cannot open portfolio

  Please help me how to reset the master encryption key.

  Kind regards

  Kalashnikoff.

  Hi currently,

  you need to reset the master encryption key by using the exact same statement:

  CHANGE the ENCRYPTION KEY SET of SYSTEM IDENTIFIED BY 'Abc123def456 ';

  
  

  The passworsd you provide is only the password of the portfolio, the MK is not derived from this, but

  using a secure random number generator, the Wallet password can be changed separately

  using owm or orapki.

  
  

  Greetings,

  Ora-00600 errors must be triggered through Support of Oracle. They have a corrector of error ora-00600 there, but it does not mean that there's something gone wrong internally and is not likely to be something that someone here can help with, unless they go to Oracle Support themselves and look it up.

• Update via subject: Firefox after the release date

  I noticed that in the latest versions of 4-6, after the official release date (for example today Firefox 38.0 was moved to release and pushed to free servers and for manual download on the site) as the day coming on: firefox does not update the program and said I use the latest version (37.0.2).

  Is there a reason for this?

  My guess: version stable/Adaptive QA in the case of a major bug
  -Tire due to an uncorrected critical vulnerability
  -Not overwhelming the server load
  -Help organizations deployment of delay of 1 day instead of trying to push several critical supplier updates every 2nd Tuesday of the month.

  I bet on the top 2 reasons.

  More information available on the subsequent restitution process after the release date? Is there a period of 1 to 2 days before the additional downloads are allowed via the built-in updater?

  • I read the timing of the release, but after the next day of the release date, there is no additional info provided

  Thank you in advance!

  fired 38 of Firefox version and updates are disabled for the time being to investigate and resolve some crashes on Windows and a version of Firefox 38.0.1 is underway and will be published in the next few days.

  You can continue to use Firefox 37.0.2 for now.

• Data are lost in the recording file

  I have problem with registration in the system binaries RT

  I started the registration of the host system

  After that some time suddenly power for the RT system disappeared

  then file was created in the system of the CR, but the data is lost

  It is showing 0 bytes

  Another fact to this problem

  My understanding is that the data is written, but indexing to access data is not done until the file is closed.  Therefore, the data are not available.

  The other possible explanation would be that the data are just put into a buffer to send on the hard drive.  There is a function buffer flush.  Maybe this will help you?

• Why the Date is always shown when I move my mouse over the clock in the taskbar? Most of the time, it works very well!

  Why does the Date not always appear when I hover my mouse by the clock in the taskbar on my Tablet? It displays immediately if I click somewhere near where on the clock.

  Often it doesn't appear when I go through the clock. Sometimes, it does. I don't know why he sometimes reacts different.

  And didn't someone jump in and start accusing malware etc. Just read my profile. That is not the issue and I don't want to be around anyone who wants just the head in this direction from the outset or even at all! Sorry on my intolerance but I think there are far too many people on the forums who dive on the issue of malware when someone asked a Question on how to change their settings to stop something that happens. I'm sick of this lazy malware junk.

  This is a bug. All XP do. Clicking the taskbar if it "development works most of the time.
