• the digital switchover failed, primary status is "not allowed".

  Hello

  I used AS5 + 11 GR 2 + dg and you have a problem after normal passage to the.

  1. the switchover_status of primary education says not 'allowed '.

  2 newspaper doesn't seem to SYNC.

  3 dgmgrl shows incorrect "database role.

  everything is going OK before the switch to digital, how could this happen and how the transition to the back?

  Thank you all.

  Which path you used for the digital switchover?

  Have you used: DGMGRL > crossing the sztestdbdg?;

  I think, you have used SQL * more to perform the failover.

  Remember, if you use managed broker keeps data, you must use DGMGRL.

  Because every thing must be changed broker managed configuration files.

  In your case, your database roles has changed, but the configuration file is not changed.

  You found this error.

  If you're used to SQL * Plus, then you must remove configuration Broker safely.

  Once you create the configuration of broker again.

• Issue of digital entry behavior

  PCI-6143 with wheel wired to PFI0 & PFI1. LabVIEW pgm written in 8.5 full. Source code works well (on other Web development pages

  computer with USB-6211 card) but hangs, as is eating 100% cpu time in the destination computer. This machine it must run on a LV 7.1 installed and some 7.1 executables. I installed DAQmx 8.8 on this machine with LV 8.5 support. I'm trying to run the executable on this machine that LV 8.5 is not installed.

  If I enter MAX, select the card and run test panels, I get conflicting results. If I choose digital IO on both channels 1 or 0 I constantly receive all 8 lights. There is no signal. But if I'm going to count, use the trigger channels and count the edges I activity. Am I missing something? I need to remove these problems before you start to screw up my source code to find a bug that does not exist.

  Thank you 1 million.

  When you add the PLS_INTEGERs 2, the result is a PLS_INTEGER.  The amount you're trying to do is greater than the maximum value that can contain a PLS_INTEGER, that's why you get the error.

  If you change the assignment statement to

  n: = CAST (p1 AS NUMBER) + p2;

  you will not get this error.

  If you suspect that you will get anywhere near the limit, you should not use PLS_INTEGERs.

• issue of digital painting

  Make a comic. When you perform a digital painting, why people color all in blue before colouring with other colors?

  This is a pencil sketch technique used by the designers of old school comics.  It is called "no photo" or "no-repro" blue.

  Blue non-photo is a particular shade of Blue , which can not be detected by the cameras of graphic arts. This allows layout editors to write notes to the printer on the print flat (the image that must be photographed and sent to print) which will not show in the final form. More than this, it allows the artists to sketch lines without having to erase after inking.

  Blue non-photo - Wikipedia, the free encyclopedia

  You wouldn't think this would allow digital, but this explains: http://comicsaregreat.com/video-making-non-photo-blue-pencils-in-photoshop

• Digital switchover and Active Data Guard

  I spin a quarter-Exadata V2 support systems (two instances CARS) and am changing my sleep Physics (an Exadata V1 rack with four RAC instances) in an Active Data Guard configuration (i.e. bearer Real - Time Query). The RDBMS runs 11.2.0.2 with BP7.
  
  My question is if I need to disable RTQ/Active Data Guard before a planned failover? If this is not the case, the transition process will automatically start QTR on the 'new' standby (i.e. my 'old' primary)? We'll test this on next month, but he was curious to know what to expect in advance.
  
  I use DGMGRL (Data Guard Broker) to manage the transition to digital.
  
  Any thoughts?
  
  Mark

  If you use the broker, as you must do with RAC, the broker must manage everything seamlessly. If it's not, and you need to test this, open an SR with Oracle's Support.

• Laser digital lock with Labview FPGA?

  Hello

  Sorry to bother if you are not interested in this issue of digital signal processing. We are looking for a possible digital solutions to our problem locked frequency cavity closed-loop laser (see attached PDF file for more details).  The goal is to flatten the PZTs transfer function (cancel the resonances and anti-resonances and their phase shift matching) in the frequency domain, in addition to the normal PID control.  Input/output necessary voltage signals are small (we have our own amplifiers high power for the PZTs), and their bandwidth must be at least of 50 kHz (100 kHz would be optimal).

  Among various OR hardware/software (DSP, FPGA, cRIO etc.), would anyone recommend a cost-effective solution for rapid prototyping?

  Thank you!

  I would like to look at the FPGA PXI cards nor 7854r.  I rate of 750 kHz, 1 MHz AO.  According to the involved treatment, you might expect between 200 and 750 kHz closed control loop.  If the treatment is very intense, it's probably something less than 200 kHz.

  That said, the key to these performance levels is not trivial and great care and attention to detail must be used in the coding of the FPGA.

  Good luck

• transition to digital with broker 12 c, failed

  With the help of a knot of CARS; While tempted to make the switch to digital, broker tries connecting standby instance that isn't the target instance or does not.

  All successful audit of the primary and standby; However, he chose the wrong instance that is not upward.  TNS alias use as an analysis in the field of the host and the broker should have pick the current service which is ONLINE or LOAN based on listener registry services.  Notice, that he took the static instance that is the first instance, the _1, position in service and is not upward; However, the second instance is _2.  Not sure if this is a BUG.

  Hello

  Thanks for the review.  12 c, validate the statement of the database on the command line broker are successful and passage of State is 'READY' that's really weird why broker is trying to make the connection to an instance that is not alive on a single node RAC approx.  As I mentioned who uses scan; Therefore, it should be treated without error.  Not sure how bad it.  That an exemption must move current stdby instance _2 and when the new instance become _1, then will try to the digital switchover.  If that will be successful, then I can do the trick.  Is that the cmd-line passage statement can be in debug mode? and how?

  Thank you

• How to make the transition to digital in 10g

  Hi all
  
  
  We have 10g database of primary and standby, I have never worked before sleep, customer wants me start switch, can you please let me know how to make the transition to digital in 10g.
  
  
  Thank you very much.

  It's the way I'm following passage in the
  ------------------------------------------------------------

  (1) check that there is no active users connected to databases.
  (2) select message from v$ dataguard_status;
  (3) select protection_mode from database v$.

  Step 1 check if it is possible to perform a failover.

  SQL > select database_role, db_unique_name, SWITCHOVER_STATUS, v database name $;

  DATABASE_ROLE DB_UNIQUE_NAME SWITCHOVER_STATUS NAME
  ---------------- ------------------------------ -------------------- ---------
  PRIMARY OFMSREGT_SIM UNAUTHORIZED OFMSREGT

  SQL >

  If you get NO allow status for SWITCHOVER_STATUS, verify that the standby database is connectivity.

  If the SWITCHOVER_STATUS column displays ACTIVE SESSIONS, you can successfully achieve a failover by adding the WITH clause LOGOFF to the statement ALTER DATABASE COMMETTRE through PHYSICAL standby

  Step 2 open the passage on the primary database.

  SQL > SHUTDOWN IMMEDIATE;
  SQL > STARTUP MOUNT;
  SQL > ALTER DATABASE COMMIT TO SWITCH STANDBY MODE PHYSICAL;

  Step 4, check the transition state in the view V$ DATABASE.

  SQL > SELECT SWITCHOVER_STATUS FROM V$ DATABASE;
  SWITCHOVER_STATUS
  -----------------
  TO_PRIMARY
  1 selected line

  Step 5 place yourself in the role of physical standby database target the main role.

  You can switch a standby database physical role ensures the primary role
  When the standby database instance is mounted mode redo apply or open
  for read-only access

  SQL > ALTER DATABASE COMMIT AT THE GRADE CROSSING;

  Step 6 complete the transition of the database ensures the main role.

  If the physical standby database has not been opened in read-only mode since the
  the last time it was started, run the SQL ALTER DATABASE OPEN to open
  the new primary database:

  SQL > ALTER DATABASE OPEN;

  If the physical database was opened read only since the last
  time it was launched, you must close the database waiting for target and restart:

  SQL > SHUTDOWN IMMEDIATE;
  SQL > STARTUP;

  Note: There is no need to close and restart other bases before (not involved in the digital switchover) who are online at the time of the failover. These databases on hold will continue to
  function normally once the failover is completed.

  Step 7 if necessary, restart log apply services on standby databases.
  He must deliver the command FRO repeat apply as:
  SQL > change database recovery managed standby database disconnect from the session.
  or
  And stop repeating applies to give
  SQL > alter database recover managed standby database cancel;

  Step 3 Shut down and restart the former primary instance.

  SQL > SELECT OPEN_MODE FROM V$ DATABASE;

  Step 9 check the synchronization between the primary and standby:

  Primary
  SQL > select thread #, max(sequence#) in v$ archived_log where archived = 'YES' group by thread #;

  Sleep mode
  SQL > select thread #, max(sequence#) in v$ archived_log in case of application = 'YES' group by thread #;

  Stop the former primary instance and restart and mount the database:

  Sense of SWITCHOVER_STATUS
  --------------------------------------------
  The column SWITCHOVER_STATUS of v$ database can have the following values:

  NOT ALLOWED - this is a database of pending and the primary database has
  not been first switched, or it's a back-end database and there is no data pending.

  ACTIVE SESSIONS - indicates that there are active sessions of SQL attached to
  the primary database or emergency that must be disconnected before the
  failover operation is allowed.

  Transition to THE PENDING - this is a database of relief and the primary database
  application of the digital switchover has been received but untreated.

  LATENT pass - the digital switchover has been waiting mode, but has not completed
  and I went back to the primary database.

  Primary SCHOOL - this is a database of pending, any sessions active, i.e.
  allows to switch to a primary database.

  In STANDBY mode - this is a primary database, any sessions active, i.e.
  allows to switch to a standby database.

  RECOVERY NEEDED - this is a database of pending that has not received the
  application of the digital switchover.

  Hi guys
  
  I have two questions
  
  1. we use oracle 10.2.0.4.0 on windows server 2003. I have two databases on a server. I just created in sleep mode for a database on a remote server. Can I create a backup of the database on the same remote server. In short, can I have two databases waiting on a remote server
  
  2. before executing the command duplicate, I created logs waiting on the primary. The location of the standby logfiles is the same as online redolog files.
  
  The pfile on my standby database file has the following
  log_file_name_convert = a: \oracle\oradata\XXXX\',: \oracle\oradata\XXXX\std_'
  Following the setting above the log files and the day before on the primary log file are copied and renamed on the standby database. My question is does redologs Eve on the backup database
  
  Thanks in advance

  Hello;

  Yes you can. I have 12 standby using 3 different versions of Oracle Server 1. ORACLE_SID and ORACLE_HOME controls this.
  If you have only one version all what you need to do is change the ORACLE_SID to issue commands.

  The double moves almost always newspapers waiting for Redo on my system it move in the FRA.

  Redo Eve are used as a buffer, the digital switchover and failover work best with them. If I remember correctly in real time if applied will not work without them.

  Your data are of course with them is the simple answer. To directly answer the question no, you don't need them. But IMHO I wouldn't have Data Guard without them.

  Redo on primary eve do not serve unless he spends roles.

• Segmented regression analysis

  Hello

  I am writing a tool that allows me to calculate a segmental curve data discontinuous, similar to example 1 or 3 here or this photo. It is supposed to consist of a linear, followed by an exponential curve to adapt, which respond to a breakpoint. Just split the data table in part did not work, because that crises do meet at the optimal point (see example 2 in the above link). Is it possible to do with LabVIEW easily existing screws, or by going in mathematics? It was indeed closed mathematical formulations for lin - lin segmented curve adjustments that could be applied more or less easily, however, I failed to find for the given problem.

  Thank you

  Frank

  Your data are quite noisy and you don't have a lot of points. This gives a degree of uncertainty and also a sensitivity conjecture of initial setting. You know more about the system under consideration? For example the point of digital switchover is known exactly? In this case, you need not suitable for it.

  This is a small project of how you could do it. Modify if needed.

  

• E/s FPGA pin delay

  I have a question about a FPGA project I'm developing.
  I use a digital RIO NI PCI-7813R, objective and Module FPGA 8.6.1
  I implement a SPI bus, master.
  I use a state machine in a single loop of Timed Cycle. (about model on one of your examples IP)
  I'm running the loop at 20 MHz, which produced a clock of 10 MHz SPI bus data.
  I send you the data in 8-bit bytes delivered by a FIFO of the host.
  Similarly, I return data bytes of 8 bits of the host by using a different FIFO.
  I have no problem sending data, generate all the select chip and data impulses on my desired clock edges.
  It's manual clean and perfect as seen on a scope / Logic Analyzer.

  When I read data from i/o pin however I have found unexplained behavior.
  It is this: the data seem to be trolling by two read operations.
  When I read the axis of I/O data to the specified limit of the clock that I generate.
  I found that the data were two bits shifted to the right, i.e., deferred, one on the scope / Logic Analyzer.
  I did a work around by two pins I/O multiple read operations in time of the gap between the data bytes.
  There are no generated clock signal and no data valid on the I/O pin at the time of these two read operations as testified to by the scope.
  And now the data received matches perfectly to the one sent.
  I can only assume that there is some kind of pipeline or delay inherent in the IO read operations. (at higher clock rates)

  I suspect that there may be something in the optimization performed in the compilation of the structure of the SCTL the cause.
  I had found it, sometime before in my development, that data has been little offset from 1 only one position.
  I think it was at a slower pace of global clock.

  I also ran the same state machine in a classic logic expect everything in a loop with an FPGA, to produce a much slower system
  and I found that there is no delay at all.

  I don't see anything in the configuration i/o pins that can affect this. (I turned off arbitration)
  Similarly, I don't see anything in the documentation that could refer to this behavior.
  8.6.1 of LabVIEW FPGA Module Known Issues (http://digital.ni.com/public.nsf/allkb/F6B5DAFBC1A8A22D8625752F00611AFF)

  I'm about to use and deploy the code with the solution because it seems to be reliable.
  But I am at a loss to explain (in my documentation of the code) why it is necessary
  or how to solve this problem if the compiler changes.
  Do you have any suggestions?

  I think that what you run is that the number of sync records used with the digital I/o.  If you right-click on the I/O item in the project and select the property page, you should see an option for number of registers for output and output enable synchronization.  These settings are global settings for this I/O item that will be the effect on all nodes of the I/O writes to this point of I/O.  Similarly, if you right click on the e/s on the schema node and select Properties, you should see a setting for number of registers of synchronization for playback.  This setting is specific to this instance of the node for this element of I/O and can be configured differently for each node in the diagram.  The effect is that each sychnronization registry will delay this beating of a clock signal.  These records are inserted to prevent the problems of metastability and ensure that you always have signal levels valid when the IO is sampled on the edge of the clock.  There is a problem whenever the producer and the consumer of the signal are market off different clocks, or at different clock rates.  If the external device drive your digital inputs work synchronous clock you are producing, you can eliminate the registers of the synchronization.  However, you must perform an analysis of delays in propagation of the signal between the two devices and make sure that all the settings and hold times are always met before.  In the end, I think that the easiest and most robust solution will be to compensate for delays in sync in your code as you do already.  I hope this helps clarify things.
