• Conversion from cold clone process in VMware Workstation

  Hello

  We would like to convert a Unix physical in our branch abroad using process cold clone with VMware Converter.

  In this industry, there is no ESX, so we will try to convert it to VMware Workstation.

  Can transfer us files from computer virtual via ssh we and configure a virtual machine on our ESX.

  The coldclone VMware is just a Windows Server bootable CD with VMware converter installed so it will convert into a virtual Workstation 3 machine. The major issues will be if she recognizes the installed physical devices (disk controller, NIC) If you are on a SUN server. If you like I want to practice so that you know what questions you have material. You can also use things like Ghost or Acronis or, possibly, Vizioncore vConverter.

• Backup Restore From Cold

  Hello
  
  I did exactly the same steps as metalink note NOTE: 174226.1 ... who is I added below.
  My problem is that when I open the database, he insists that system01.dbf is in need of a recovery.
  and when I «alter database recover...» "she complains redolog files and archive.
  When I followed the steps, after the installation of the database shut down a few times and go back again. could this be the problem... I don't know maybe he's confusing on the checkpoints etc because I read that when you restore from a cold backup the last log file must be identical to the backup day. could this be my problem? or any other suggestions?
  
  
  Prerequisite: The copy is between 2 machines, both must be on the same OS
  and have exactly the same version of the installed base.
  
  1. make sure that the database copy was closed with an IMMEDIATE STOP,
  NORMAL SHUTDOWN or SHUTDOWN TRANSACTIONAL.
  2 copy the init.ora files and control to create the instance and be able to go
  editing mode. Check the init.ora for places where the controlfiles
  be, if those places are not valid on the computer, place control files
  different places and adjust the init.ora accordingly.
  3.a. copy the data files (all).
  b. copy of the redo log files (all).
  4.a. (Unix only) set the environment variables:
  ORACLE_SID - name database that you want to create
  ORACLE_HOME - the value of the full path of the Oracle system base directory
  PATH - should include $ORACLE_HOME/bin
  b. (NT/2000 only) 'set ORACLE_SID = < SID >'
  Oradim to create the service for the instance. For more information
  oradim please consult (the part that relates to the creation of a new instance):
  Note: 68720.1 Create a new 7.3, 8.0, 8.1 Database Instance
  
  5. use servermanager (check the name to use for your version of oracle) or
  sqlplus (version 9i and above) at the start of the database in editing mode.
  Do
  CONNECT INTERNAL / < PASSWORD >
  then
  STARTUP MOUNT
  Then do a renaming of data files copied if they are not in the same way as on
  the other machine. For all the files that are in the result of the query:
  SELECT NAME FROM V$ DATAFILE;
  do
  ALTER DATABASE RENAME FILE ' < oldfullpath >-< Filename > ' on <
  newfullpath >-< Filename > '.
  6. the datadictionary for the former location of the using queries redolog files:
  SELECT MEMBER FROM V$ LOGFILE;
  If the new location is not the same as the old:
  ALTER DATABASE RENAME FILE ' < oldfullpath > \ < redologfilename > ' to &
  Lt; newfullpath > \ < redologfilename > ';
  7. now, open the database:
  ALTER OPEN DATBASE.

  I guess that the instance had increased the first time you have attempted a copy.

  Yes, your second attempt must be correct.

  Normally, the TEMPORARY file doesn't have to be copied. It can just be added after the ALTER DATABASE OPEN - see the other forum thread that I have provided a link to earlier.
  In addition, the 'normal' recommendation in the Oracle documentation is NOT backing up online redo logs (in fact, if I remember correctlly, the 10g tips strongly this!). But yes, if you ensure that the closing was of database completely, then you can save the recovery online newspapers - but a number of 'experts' would jump on me to say.
  Seems like heresy today to back up the online redo log. The reason is that a DBA could get lazy and use the 'save and restore online redo log' method even when restoring an old backup and wanting to rollforward using the archivelogs. If he does this (it means combining log redo with archivelog restoration online restore + applies), it will eventually lose the transactions in the last set of newspapers and could be confused as how to open the database (it would have to do a resetlogs, as much as it fact sufficient archivelog to ensure the consistency of all data files).

• A reading from an arbitrary point in the buffer

  With the help of the DAQmx API, is there a way to read part of the buffer from some indexes (non-zero) to aribitrary?  I would like to combine this technique with the recall of DAQmxRegisterEveryNSamplesEvent, so that I can post a video screen to the GUI of what the system during a long acquisition.

  There are two properties in DAQmx can be useful for you: the Offset and the RelativeTo property.  Changes in parameters offset in memory where read buffer begins, and the RelativeTo parameter determines what is this offset with respect to (for example the first sample or the most recent sample).

  Int32 __CFUNC DAQmxSetReadRelativeTo (TaskHandle taskHandle, data int32);

  Int32 __CFUNC DAQmxSetReadOffset (TaskHandle taskHandle, data int32);

• Win 7 Pro (x 86) Log in password is asked upon resuming from standby or hibernation

  It is a fresh install of Win 7 Pro 32 bit.

  I'm the only user, the guest account is disabled.

  To avoid the login screen I ran netplwiz and unchecked the "users must enter username and password...". "followed the instructions to fill out and restarted.

  From the pc from cold start or re-starting (reboot) the PC starts directly in the office (as it should), but the PC comes out of standby or hibernation in the connection screen and I have to enter a password.

  How to eliminate the need to enter a password during the recovery of the standby and Hibernate?

  TIA

• Cold backup RMAN

  Basically I ask this question for a problem surrounding in another thread, but here go us:

  Suppose we take a COLD backup. I know, not something directly related with RMAN, but further action is:

  This guy says: I take a backup to cold, I copy the files to another server, on which he has made the necessary in order to start this database.

  But then, since the backup and the time of the action above, time is up.

  So, there are archived redologs... because the database is in archivelog mode.

  And he wants to do what is obvious: use these Redos archived, to update the database at a later stage in time.

  To be clear; the Oder archived are created by the source database. The target database has been copied and started, nothing else.

  If the backup is a backup hot, without issue. But because the backup is cold, it is not possible, right?

  My idea is that he must also take a hot backup, in addition.

  I asked already, and despite the execution of the database in archivelog mode, the backup must be taken cold, backup mode for some reason. It is probably the old method, who they now want to just add redolog recovery, but without change from cold to hot.

  At some point, RMAN must be running, of course.

  I guess that RMAN is used for the entire operation, not "at some point" (I see no reason not to).

  The cold food at the start is to make a clone. THEN, the question is asked, but can we also restore to a point more recent in time?

  Yes, you can recover the "clone" until a more recent point in time as long as you do not OPEN it, and you have all necessary archivelogs. The sequence:

  1 startup nomount

  2 restore controlfile

  3. change the editing of the database

  4 restore your cold backup (do not open the database)

  5. If necessary, catalogue archivelog backups

  6 back to the desired point in time

  7. alter database open resetlogs.

  But I repeat, why did you stop your databases, if that is not necessary? (of course I think of my dozens of databases 24 x 7).

• Buffer max metadata

  Hello dear gurus!
  
  According to ducumentation:

  the cache buffers chains latches are used to protect a list of buffers in the buffer cache.
  These locks are used when searching, adding, or removing a buffer from the buffer cache
  
  Blocks in the buffer cache are placed on linked lists (buffer cache strings) having a stranglehold on a hash table

  how to fit between them, buckets, tampons, handles, blocks, and a hash table?
  
  I'm usung 10.2.0.5
  
  Thank you and best regards,
  Pavel

  >

  Hi Pavel,

  How match between them, buckets, tampons, handles, blocks, and a hash table?

  It's a matter of big and certainly not one that can respond to a single post.

  What I would say to you is to get your hands on Tom Kyte Expert database Architecture
  and work there. This will give you a good overview of the architecture of Oracle and others
  of what you mentioned above.

  Then you can watch Jonathan Lewis base Oracle and Steve Adams Oracle 8i internal services.

  Keep an eye on the blog of Jonathan Lewis, Tanel Poder and follow their blog rolls.

  It of a great topic and will require a lot of reading, but start by Tom Kyte - you can't
  need more according to your needs.

  HTH,

  Paul...

• Archive log file bloat - is currently out of cold back to the top of the best strategy?

  Hi friends,
  
  I have a database 10 g. / WinSvr2003 making heavy spatial processing of the Oracle.
  
  Previously, I ran the database in log mode archive and sparked a lot of files to archive log. 150 G (the worst week).
  
  I got fed up with backups (incremental) RMAN night heavy and put the database in a mode non - archive journal. (I was also worried about the time to get the data back out of band).
  
  Now, I come to launch the next nightly bat file: -.
  
  oradim-stop-sid DEV - syspwd *.
  
  del /S /Q D:\oracleBackup\DEV\*
  
  XCopy/e D:\oracle\product\10.2.0\oradata\DEV D:\oracleBackup\DEV
  
  oradim-startup-sid DEV - syspwd *.
  
  ----------------------------------------------------------------------------------------------------------
  
  1 week ago - when I arrived-in the morning the database had not restarted due to an inconsistency of data file.
  Recover the database fixed.
  
  I guess he had something that this necessary in the redo log files? (its mode no - archive).
  
  I have a DB 24/7.
  
  This cold offline backup is the best strategy to avoid the bloat of log file archive
  
  I can always use RMAN and do not back up files of newspaper Archives? How can I make sure that it is a consistent RMAN backup if she has no access to archive the log files. (I just use RMAN after an immediate stop - restart?)
  
  How instruct you RMAN is not to get the files to archive log?
  
  DATABASE INCREMENTAL LEVEL 0 BACKUP; <-this leaves archive the log file out of the backup.
  
  Thanks in advance.
  
  See you soon,.
  
  AA
  
  P.S. This is my first post on this forum. Yes!

  If you
  a. make a backup of the database CONSISTENT (that is to say in MOUNT but not OPEN) with RMAN
  b. do not save the ArchiveLogs
  c. yet the ArchiveLogs to create the database in ARCHIVELOG mode,

  You can still use the combination of consistent backup and ArchiveLogs generated since the backup database (assuming that the ArchiveLogs are still on the disk) in the method of 'Refresh '.

  In other words, RESTORE (but not RETRIEVE and OPEN) the database of the RMAN.
  Using sql RESTORE DATABASE with the HELP of BACKUP CONTROLFILE to 'Updating' then apply ArchiveLogs for what is just restored.

• MacBook Pro (retina, mid-2012) will not start

  I have the mac above and I have a weird problem. The mac wouldn't start, I could hear the fan running and if I pressed the power button I can hear her stop.  There is no visible display or no light. the shift lock lights.  Charger lights work normally, if I reset the SMC, the light on the charger goes from green to orange and green. I contacted Apple and they could not help, we have also reset the PRAM.

  I left it on and then when the battery was completely dead, I plugged in the charger and tried to turn it on, I was rewarded with the icon of the dead battery, progress! After a few minutes that he started ok, I had the Apple logo and progress bar and then start.  Alls well well except when he went to sleep, she would not start again until I have go through the flattening of routine battery.  I now have reboot, stopped, started from cold, sleep and he waken up - everything looks ok.

  My question is there will be any newspaper to show what was causing the machine does not go to sleep?  I lost confidence and am very reluctant to go to the genius bar as I don't think they understand the problem.

  Thanks for reading

  All saved entries are found using Console in your Utilities folder. Is simply a software problem, then you can erase the drive and install a new copy of Mac OS X. If it's a hardware problem you need an appointment with Apple Genius Bar for the service. If you need a Apple Store - find a store - Apple.

• Portege R700 - quick as lightning!

  Despite some reports of 'flaky' and similar operation, I decided to tear off my HARD drive and slap a SSD and W7 Pro 64 bit on my portege R700-184

  flippin heck its the thing to the top fast!

  I used a base of sandforce OCZ Vertex 2 120 GB drive and the Retail Media to install the 64-bit windows. It's with any other firmware or software update for the SSD or Laptop, so right on the box

  Before starting from cold to 95 seconds, down to 23 seconds on the SSD used! and he wakes up from his sleep in 4 seconds! VERY impressed!

  Similarly the 64-bit operating system has improved my WEI scores the CPU is 6.5 to 6.9, the RAM of 5.4 to 5.9 and obviously the SSD took a hard drive of 5.9 to a burning 7.4 :-)

  excellent upgrade in the embryonic stages, I will present long-term stable after that I have all my drivers and running upward and restore my files!

• Missing built-in Ethernet

  I have been using built-in ethernet, including the last 2-3 weeks clean installed El Capitan without problems. Today, inexplicably while working all of a sudden I'm not connected to the Internet. Network group says cable is not connected, and the usual troubleshooting ensues. I deleted all panel network connections, and the elements of Network/Library/Preferences and rebooted several times, and now network it is even not an ethernet interface. Information System > watch only network: bridge of Thunderbolt and a Wi - Fi, FireWire, Bluetooth PAN. No ethernet.

  OK, so I start a live image of Linux Fedora, he sees and uses the Ethernet very well. So the material is clearly OK, it seems that the OS has somehow planted face.

  Boot with command-r and Safari in the recovery environment works fine on built-in ethernet. Restart the system installed, and it is still not found. The only clue in the system log is:

• Equium M50-244 blocks black screen then restart

  I am currently in a laptop for a friend he pays a month of repair of malfunctions on his laptop, world pc so he sent 2 times back and the above error is still there

  the laptop started to hang and make the mistake of ati bsod

  now, I tried to clean the system and reinstall xp, I'm so far through the installation and then it crashes

  then when I try to reboot the screen is all black and if I try a monitor is just the same

  also crashes for the memtest86 + after that about an hour from cold start or 10 minutes of a boot hot and the laptop does not warm start

  What is CPU or gfx questions?

  can someone please tell me what to do

  Hello

  This problem may be related to different hardware parts
  You said col didn t of memtest86 + test correctly although this means there could be a RAM problem.
  You said that the screen becomes black and a BSOD with ATI error appears also that this would mean that the graphics chip is not ok

  It would also be possible that the temperature high inside the cell affects mobile functionality eventually the graphics chip becomes hot and that is why temperature affects the RAM and the laptop freezes.

  What to say if the graphics chip is the reason for this while the whole motherboard must be replaced and a motherboard is not cheap

  Maybe you need to find a second hand M50 and could replace the motherboard in order to test it

  Hello

  Sorry khar khar?   Mainly under the keyboard sounds would be Fan or HARD drive that could mean either the fan (if fan) is struggling to move due to dust build up OR the hard drive is a failure, it is difficult to give you a firm answer without more information. Can you tell the difference between the noise of the fan and hard drive noise?

• How to acquire samples still?

  Dear users of Labview

  I am new to Labview FPGA programming, and I have a 7962 SMU with a NI5734 or a NI5751.

  I want to acquire several channels simultaneously at 20 MHz.

  From what I can see in the examples and forums, I intend to create an fpga vi where I acquire signals at the same time using simple - cycle loops timed and store them in a FIFO with channel and then read the FIFO of the host. But I am confused on how to do it for more than the size of the FIFO without interruptions of the signal.

  Indeed, I would have preferred 1s of the acquisition, which gives 20 M per channel data (up to 16 channels if I use the NI5751). How can I do? Because the FIFO size will never be large enough to store the data of 20 M, but how to make sure the transfer between the target fpga and host is continuously without interruption in the acquisition?

  Thank you for your help.

  If you are thinking to continuously, do not think in terms of the finished sample size.  You don't want a 1 s.  You want continuous samples.   Another way to think about this is as a stream.

  See help-> example Finder and search for DMA streaming

  This should help you get started on a memory stream buffer from the FPGA to the host PC.
