Reset sequence

• ORA-04092 immediate execution may engage in a trigger - Reset sequence

  Hi all. I'm trying to reset a sequence of a procedure that is triggered in a trigger. The reason is that after each new transaction, a new series of point number must be generated, numbering each line as 1, 2, 3... After a new transaction, I need to start from the beginning again. The procedure is
  

  PROCEDURE Reset_Item_Serial_No IS
    
      Serial_No  NUMBER;
      p_seq_name VARCHAR2(20);
    
    BEGIN
    
      p_seq_name := 'SERIAL_NO_SEQ';
    
      EXECUTE IMMEDIATE 'SELECT ' || p_seq_name || '.nextval FROM dual'
        INTO Serial_No;
    
      EXECUTE IMMEDIATE 'ALTER sequence ' || p_seq_name || ' INCREMENT BY -' ||
  
                        Serial_No || ' MINVALUE 0';
    
      EXECUTE IMMEDIATE 'SELECT ' || p_seq_name || '.nextval FROM dual'
        INTO Serial_No;
    
      EXECUTE IMMEDIATE 'ALTER sequence ' || p_seq_name ||
                        ' INCREMENT BY 1 MINVALUE 0';
    
    END;

  This procedure is triggered by the following section in the trigger:
  

   SELECT COUNT(*)
        INTO v_Reset_Sequence
        FROM supply_items s
       WHERE s.requisition_code = v_refno;
    
      IF v_Reset_Sequence = 0 THEN
      
        account_interface.reset_item_serial_no;
      
      END IF;

  I can not use TRANSACTION INDEPENDENT of PRAGMA, the db detects this and restores. Advice, is to make the enforcement procedure, or somehow create a sequence number, whenever I need to insert a new transaction?

  In your case, I'd rather not a sequence. As your requirment is transaction after I'd go with a GTB (global temporary Table).

  Here is an example.

• CHANGE the SEQUENCE on a busy server translates into very high unexpected values

  Our sequence was 782,393,232, or so, when I came it up through 30 000. Here are the commands I used:
  
  change the sequence of OUR_SEQ increment in 30000;
  Select double OUR_SEQ.nextval;
  change the sequence of OUR_SEQ increment in 1;
  commit;
  
  When I questioned nextval in the sequence, a few minutes later, he had climbed up to more 8 billion! I have reset quickly up to 783 million or more, and it behaved correctly after that. I saw some posts on the net that infer that the reset sequence is heavily used can cause "unpredictable." Everyone knows this or y at - it a bug known?

  Sven,

  I'm not sure I understand what you're clarifying...

  In a CCR cluster, a sequence with a cache has a separate cache in each node of the cluster. If the cache has been set to 20 (the default), and the increase was set to 30,000, each node is hiding 20 values separated by 30 000. And caches would be overlapping (i.e. node A would get 20 values of 1-570 001, node B would get 20 600 001-1 170 001 values). I don't see that this is in contradiction with what I posted.

  Obviously, the presence of a cache creates a bit of a ride with when, exactly, you say that a sequence is incremented. The NEXT_VALUE in DBA_SEQUENCES is incremented by cache * interval when any node exhausts its cache. The NEXTVAL of a sequence for connections that hit a particular node will increase by interval every time another session gets the NEXTVAL of a sequence. The NEXTVAL of a sequence for connections on a different node is not affected by what is happening on the current node. What enlightenment do you? If so, I agree.

  user11300030,

  Discussion on the sequence of caching can provide insight into why none of the lines are between 780 million and 1 billion. It is quite possible that these values have been cached on one node other than the node where the pads were executed. Had caches was flushed not when change you the sequence, inserts run on these other nodes could have used this range values.

• Airport Extreme in brick after update firmware 7.7.7

  Error while trying to update the Airport Extreme (model A1521) firmware to version 7.7.7.  After clicking on "Refresh" for the EPA in the utility AirPort app on my MBP, it seemed like it was downloading and then restart, but then the "error during firmware update" message popped up.

  Then he disappeared from the AirPort Utility app. check the physical EPA, he got a quick Orange flashing light on.

  Perform a "hard" reset No change.

  Perform a reset "factory".  Solid green LED for 1 second, off for 1 second, then fixed Orange LED for 5 to 10 seconds, then orange flashing LED forever.

  Removed all connections to the EPAS, repeated above steps with identical results.

  Tried to plug the cable to all ports, a both MBP, then in a port to a different router.  No connection.

  Base from the bottom of the EPA to inspect the connection with the ohmmeter removed rubber physical reset button. Button contacts are open when not depressed, short circuit when pressed.

  EPA appears at all in the AirPort Utility (not in "Other WiFi devices" or the other).

  Pushing the reset button on the EPA has no effect, no matter how much time or when it is pushed.

  Once the power cord is removed and inserted, the indications are always the same, no matter what I do with the reset button. Green LED for 1 second, off for 1 second, Orange fixed for 5 to 10 seconds, then orange blinking forever.

  Interaction ONLY with the device, which had until this point was working perfectly for years, has been through the AirPort Utility software.  Physical interaction occurred after that the update of the firmware he bricked.  Simply, I do not understand how a botched firmware update might brick the MONKEY.  The default firmware must always be able to be loaded with the reset sequence.

  You should not open it... Apple may have been told by replacing.

  Firmware updates are always dangerous... the airport less then most of the routers.

  However very rarely something can go wrong and the firmware written correctly to the ROM. This will leave the router in a State of broken forever. You need to replace unfortunately.

  Hi Donald,.

  Welcome to the Community Forum of HP.

  I'm not the only one to help you with this; I never - ever - was able to get the version of series 8 HP SimplePass software works correctly.  When I was able to run, he soon blurred place a small ball of code-waddle.  Sigh.  I use the 6 series, the old version of AuthenTec's HP SimplePass - is no longer on the list official "support" but used by many and, oh, so strong and vigorous.

  However, series 8 is the official version of these days AND 8 series is the version that comes with the latest laptop computers.  Series 8 is the future.  We move.

  If - the following may be useful that everything else is equal, and the universe is not against you:

  Reference:

  ENVY of HP TouchSmart m7-j120dx Notebook PC drivers

  HP SimplePass upgrade instructions

  If your HP SimplePass is a heap of smoking rubble (broken):

  Jump down to about Page 10 (updated) - Look / search the Section Hard Reset séquence

  Next:

  See the Section on Page 2 (updated):

  HP SimplePass and fingerprint Scanner Support Document - Windows 8

  Then, if necessary:

  Better, you can complete the procedure / steps in the section:

  Procedure - updated / (install HP SimplePass Re)

  NOTES:

  • Observe the warnings that the series 6 and series 8 HP SimplePass are not the same program.  Do not try to install series 6 HP SimplePass on a computer on which you have already installed the 8 HP SimplePass series.  While it is true that we can term series 6 HP SimplePass on your laptop, you cannot have the two programs on the system at the same time.  They are not compatible - they were written by different programmers - they were written by competing companies - programs do not like each other.
  • Remember that series 8 has no 'fix' option for the 6 series mentioned in the Guide.  You need to reinstall the HP SimplePass software (available in the Guide, or in your case, Don, site Web on your computer supports pages).
  • For best results, do not skip the reboot / reboot sequences.  Windows like a good restart.  HP SimplePass really enjoys a good reboot sequence; the database is a fussy code fish.
  • If all else fails and you have tried everything and that the universe is against you - completely remove the program from the computer, perform the Hard Reset sequence - do not forget this isn't, won't erase your computer - and then, very slowly, start on the Section:

  Procedure - updated / (install HP SimplePass Re)

  • Don't forget that if you want really to CONNECT using your fingerprint, you HAVE not even fingerprints - Windows 8.1 has its own connection software native of fingerprints that will at least you connect to Windows.  You cannot use it to control the Web sites, but you can get at least on the computer by using the fingerprint reader.

  Good luck!

• OfficeJet 6500 wireless mode ensures no wake upward

  I have a wireless 6500 newly installed.  Once he falls asleep for a while (on the order of hours), he refuses to wake up.  The power button and not another button on front of it will bring to life, is not accessible via radio.  Only a restart of power switch it will bring back to life.

  A side effect, we noticed with latest FW upgrade Apple their Airport Extreme wireless routers is that our printers is no longer a default gateway IP address.  This should only affect printers that make outbound connections to the internet, as some of our printers.

  When you set a static IP address in our printers, you need to set the (usually 255.255.255.0) subnet mask and the default gateway IP (usually IP address of your network which is the IP address of the printer with the last byte to 1).

  I don't know if it's what you see with your Officejet 6500, but affecting a static IP address does not hurt as long as the printer is still on.

• OfficeJet Pro L7680 dropped off the grid, indicates 'No Link'

  I have been using this printer for about 3 years on my home network.   I assigned a static IP address, and the family had been printing happily.   A few weeks ago, the printer is offline and I was not able to put it back on the network.   We can print correctly by using the USB cable, but it does not help when the computer is a desktop machine in another room.

  I tried the automatic (DHCP) and manual settings on the printer, but I cannot be granted on the router, not to mention all the client computers.

  When I go into screen manual IP settings on the printer control panel, it shows 'No. Link' at the bottom.    The router not indicate any ethernet connection on the port, I have the connected printer.   Changing the port on the router has no effect, and other ports on the router are working fine (cable the computers are online).   When I look at the Ethernet on the back of the printer, I see a yellow light and a green light.  When I unplug the ethernet of the printer connector, the Green and yellow lights will remain lit.

  My theory is that there no ethernet on the printer controller.  If someone can tell me what means 'No. Link' and a green and yellow light?

  Sorry - seems bad.  You could try to reset the configuration of the network on the printer and then put cycling on the printer.

  If this does not work, then you can try a partial reset (hold it # and 3 keys while you plug in the printer and turn on).  You can also try a reset full semi (# and 6 keys) and a complete reset (# and 9 keys) as well.

  Note that you will lose all your settings with these reset sequences.

  Good luck.

• Creating primary key based on the Date

  Hi all
  I am trying to create a unique ID for each record, based on the date that the record is created. Example, if the folder is created today, I want to the key is 20101130XX where XX is a sequential list of numbers e.g. 01, 02, 03 etc... in the case where more than one person creates a record today.
  
  If 3 people created record yesterday their unique ID would be
  
  2010112900
  2010112901
  2010112902
  
  and then comes the midnight and someone creates a new record, that it would be
  
  2010113000
  
  This is intended to give each record with a unique ID that will be used to reference the ticket.
  
  We are already using the date format, but currently users have to manually enter the id and who can create errors such as 2011112900 when it should have been 2010112900 then instead of 2010 they put 2011
  
  I'm not sure how to create a trigger to generate this type of unique identification number and would appreciate any help
  
  Thanks in advance

  Never said it was perfect, but then again, it is a rather sticky issue... Reset sequence work would be scheduled to run @ some point... You entered in tables past 24/7? I would say that system could be locked for those 5 minutes sequence is updated, or the table is locked to allow no access while the process is...

  To be honest, that is the question in the design of a key value that is dependent on outside data, as apposed to a surrogate key, which is generated System... Again, you could have at ONCE and have the surrogate for a key key REAL primary and date + sequence as a secondary key for the use of basic unit of carbon...

  Yes, you can as in my sample code above. The bind variable are just placeholders, so you can call it what you like. What you should remember, is that you can only bind in values, not the column names or table names.

• Reset oracle sequence

  Hello world

  with the help of an ETL tool I'm migrating data in oracle database tables here I do not use oracle sequence. After the migration, I have to reset the sequence.

  ex: table: employee, name of the sequence: employee_id_seq

  initially:

  create sequences employee_id_seq

  start by increment of 1 by 1;

  data in the Employee table:

  employee_id ename

  --------               ---------

  1                    aa

  5                    bb

  6                    cc

  to restore order, I drop this sequence and recreate the sequence

  IE.,.

  employee_id_seq sequence of fall;

  Max (employee_id) here is 6 nextvalue is 7.

  create sequences employee_id_seq

  starts with 7 increment of 1;

  Select double employee_id_seq.nextval;

  nextval:

  --------

  7

  instead of delete and re-create the sequence any other method is there to reset the sequence.so, I want to create a dynamic script that will reset all of the sequences.

  Please advise on this.

  Thank you
