• FF has been fast, responsive and reliable. is not so much now

  I used once FF exclusively, it was great! I recommend it to everyone and even install it to people so that they can enjoy it also.
  Then for some reason any (over several years), it has become slower, inflated and would break more frequently, so I changed to a different browser.
  Given that I liked FF, I thought I would give it another go, but instead of an improvement, I think it is seriously degraded, crashing in the first run after installation.
  I'm really sorry for Mozilla, that's a shame.
  You guys have had a hand Director on what the internet should be since the early days, and I'd be happy to support you with your products and recommend once more; But if I can't run it myself immediately after installation, it is almost impossible.
  In this situation I saw simply google.com.au, adobe.com , and learningspot.com.au indicate that the browser completely locked up after loggin, with no indication that he had crushed other than a total lack of response.
  I will say that when I clicked on the X to close FF, it worked, but I see no dump on incident or any other information that might help solve this problem.
  Please understand during my presentation can its negative, it is constructive criticism, and if I had the crash dump, fortunately, I'd send it your way.
  I am pleased to send you the MS System Info dump if it would help at all (57 KB in 7z format).

• the question of the overall index was updated

  I have a partitioned table and the local partitioned indexes in 9i. In the past, when I add a new partition, partitioned indexes have become "unusable" so I have to rebuild the index to the "exploitable": State
  
  ALTER INDEX REBUILD PARTITION myindex TYPE my_partition nologging;
  
  I just found out that when you use the clause to UPDATE GLOBAL INDEXES, there is no need to rebuild the local index in the underlying table. It seems that updating the GLOBAL INDEX also update local index to the status of "exploitable".
  
  create tablespace you see
  
  ALTER TABLE my_table SPLIT PARTITION of VALUES 'TYPE_DEFAULT' ('new') INTO (PARTITION "TYPE_NEW" TABLESPACE "you see", "TYPE_DEFAULT" PARTITION) UPDATE GLOBAL INDEXES;
  
  I wonder if UPDATE GLOBAL INDEXES also update local indexes as it appears in this case. I thought that the UPDATE GLOBAL INDEXES only updated global index.

  Interesting! Can you post the DDL that you use for the table and index, so we can try to reproduce it?

  This seems to contradict what said documentation, but that would not be something new.

  See "Split of Partitions" in the Guide DBA 9i
  http://docs.Oracle.com/CD/B10501_01/server.920/a96521/partiti.htm#6736
  >
  Behavior of the index

  Regular (TAS)
  Oracle UNUSABLE brand new partitions (there are two) in each local index.

  Unless you specify GLOBAL INDEXES to UPDATE, all index global, or all partitions of global partitioned indexes are marked UNUSABLE and must be rebuilt
  >
  Also you not "add" a partition you split one and creates two new partitions, which both can have data. These two partitions of the local index must be rebuilt.

  When you "add" a partition it lacks all the data so there is not need to rebuild the local index for this 'new' partition.

• overall index using partitioning of the interval.

  Can we have an index that is partitioned across the world using range partitioning on the number field in the database table.

  Can we have an index that is partitioned across the world using range partitioning on the number field in the database table.

  No - a global index cannot be paritioned of the interval.
  You can create a range partitioned or Hash-Partitioned Global index, but it cannot use partitioning interval. The index may be on a table is partitioned apart, but the index itself cannot be partitioned apart.

• New MBP and two raid 0 drives 4 GB 7200 rpm or replace a small SSD

  Hello

  I apologize if this in the forum somewhere.  I'm looking for 4 hours through the posts and cannot find an answer to this question.

  I ordered a new Macbook Pro products listed below.

  MacBook Pro 15 inch with Retina display

  • 2.8 GHz Quad - core Intel Core i7, Turbo Boost up to 4.0 GHz
  • 16 GB 1600 MHz SDRAM DDR3L
  • Storage 1 TB PCIe Flash
  • Graphics card Intel Iris Pro + AMD Radeon R9 M370X with 2 GB of GDDR5 memory

  
  

  In my research, it seems that the best configuration will add two additional discs.

  
  

  I want to purchase the LaCie 9000601 robust Raid Thunderbolt.  Its configured as a RAID 0 4 GB (2x2gb configured raid 0) read and write speed is rated at 240 MB/sec.  For the third disc is there going to be any speed up if I did for one SSD drive with read and write speeds above 400 MB/s?  If I won't see any significant speed I would make the 3rd disc an additional LaCie.

  
  

  So the two configurations:

  #1

  C: 1 PCIe storage to Flash

  D: drive for raid 0 4 GB lightning

  E: drive for raid 0 4 GB lightning

  
  

  #2

  C: 1 PCIe storage to Flash

  D: drive for raid 0 4 GB lightning

  E: 500 MB SSD with reading and writing of at least 400 MB/s

  
  

  I will mainly be 4K video editing from a 3 ghost drone.  Most of the videos will need only some basic edition/transitions and possibly a color correction.  I would like to modify in real time or near it and have always render as low as possible. I will be editing in Premiere Pro CS6 and could switch to CC.

  
  

  I appreciate all the comments.  If it not is not much of a difference, I would #1 configuration where it provides an extra 3.5 GB or storage and is cheaper at the same time.

  
  

  Thanks for your comments and help.

  
  

  Gary
  

  It seems that the ghost 3 mp4/h264 files? These files will be slightly compact vs other formats, reducing the demand placed on the disc. LaCie rugged raid should operate correctly for the media to hold, and then you can set the project on the C: drive cache. If you work on small projects, you will be able to store everything on the flash disk and the backup to an external drive. If you want to keep on an external drive media, the DSS will provide faster response times to access the various elements when editing.

• nxGetProperty sometimes takes a long time

  Hi all

  I use a 9862 (XNET CAN interface) in a 9068 (cRIO controller).

  In my software (c / c ++ in eclipse), I have a session for each ID CAN (currently 4 out, 9 in.).

  I use the FrameInQueued mode with queue messages, CAN to incoming size 1.

  Then I'm just checking if there 'something' again in the loop in real time using nxGetProperty (session, nxPropSession_NumPend,...)

  Most of the time it works fine, but sometimes (distance approx. 10 s), this feature needs about 7-8 MS (once a line) that is much too much, because my loop has only 10 ms and there is much more to do in a loop.

  My app sends outgoing messages CAN by using FrameOutSinglePoint in the same loop.

  There is no thread using xnet functions in my application.

  Any ideas for the reason?

  How can I get rid of this behavior?

  Thanks in advance for your answers,

  Jens

  Hello

  Take a look at this:

  Getting started with the API OR-XNET for LabVIEW - National Instruments
  http://www.NI.com/white-paper/12375/en/#toc4

  ...

  In NOR-XNET, session for e/s single point modes are designed for use in loops of high priority. This applies to all four modes of single point: input, output, signal or framework. XNET Read.vi and XNET Write.vi provide fast and consistent execution times, and they avoid access to shared resources, such as the memory manager.

  Modes other than single point session all queues to use it to store data. You can use patterns from session queue in a loop of the high level of priority, these modes of use a variable amount of data for each read/write. It takes a variable amount of time to process the data, which can introduce jitter to the loop. When you use the modes in queue, measure the performance of your code in the loop to ensure that it meets your requirements even when bus traffic is

  ...

  If you get only in single point IO a timing loop deterministic and reliable,

• Get the response time more with First_Rows Hint.

  Hello
  I use 10.2.0.1.0 oracle version. I have a sql query that gives performance with cutting-edge FIRST_ROWS problem.     I expect the best response time with suspicion of "FIRST_ROWS (5)", but his is the worst, with use of a different set of the index, which is local to the partition. Please, help me to understand, the reason behind this change in negative execution path?
  

       First query gives all the ~3488 rows within ~1 minutes but the query with HINT is taking ~15 minutes for providing initial few rows itself. 
  For second one i am not able to get the exact and estimated cardinality stats , as it was taking lot of time for completion, so providing Autotrace plan only.

  Yes, Jonathan, in fact in the first case, i 'I' table is being analyzed using an overall index, but suspicion FIRST_ROW sound using the index that is local to the partition. resulting in the digitization of all partitions of 448. I think it's causing bottleneck. Is there something like: FIRST_ROW suspicion that affect this type of systematic index scan?

  In the first case the optimizer has unnested subquery of REACTION and used to bring to the table, I, and that's what dictated the choice of index.

  In the case of first_rows (5) decided that the range index scan will take adequate data if some time he chose a different index - running subqueries in the REACTION as a subquery for filter on each line. But it is the estimate of how long it will find adequate data (and how much time he will have to run the subquery to eliminate unnecessary data) does not.
