• The slow queries with WITH and JOIN

  Hello
  This code takes too long to complete:

  WITH rawData AS -- 563 rows in 0.07s OR 59 rows in 0.02s
  (
  SELECT
       date_releve AS x1,
       index_corrige AS y1,

       id AS id_releve,
       id_compteur
  FROM V_relevesCorriges
  ),
  
  meteoData AS -- 1082 rows in 1.34s OR 116 rows in 0.16s
  (
  SELECT avg(meteo.valeur) AS meteoValue, x2 AS dateMeteo, id_variable, id_releve, id_compteur
  FROM meteo, rawData
  WHERE date_meteo <= x2 AND date_meteo > x1
  GROUP BY id_releve, id_variable, x2, id_compteur
  ORDER BY x2
  ),
  
  consoData AS -- 1104 rows in 1.43s, 117 rows in 0.2s
  (
  SELECT
  to_char(x1, 'DD.MM.YYYY') || ' - ' || to_char(x2, 'DD.MM.YYYY') AS periode,
       meteoValue AS meteo_moyenne,
       (y2 - y1) / nullif((x2 - x1),0) AS conso_par_jour,
       (y2 - y1) AS conso,
       rawData.id_releve id_releve,
       meteoData.id_variable id_variable,
       meteoData.id_compteur id_compteur
  FROM rawData LEFT OUTER JOIN meteoData ON rawData.id_releve = meteoData.id_releve
  ORDER BY x2
  )
  
  SELECT periode, meteo_moyenne, conso_par_jour, consoData.id_variable id_variable, consoData.id_releve id_releve, id_compteur -- 1104 rows in 1.51s, 116 rows in 1.34s
  FROM consoData LEFT OUTER JOIN diagnostic2 ON consoData.id_releve = diagnostic2.id_releve AND consoData.id_variable = diagnostic2.id_variable
  WHERE Id_compteur = 4

  If I remove "WHERE Id_compteur = 4" on the last line, there is almost no difference in run time. Without this WHERE clause, it returns 1104 ranks in s 1.51, with her he returned 116 lines s 1.34.
  
  I say it takes too long because when I put this WHERE 'consoData' clause (WHERE meteoData.consoData = 4), he returns to 0 116rows. 2 sec., to get the same output of data. If I remove the LEFT OUTER JOIN diagnosis2 (last but one line) there are also 0. 2 s.
  
  I think that the solution would be to force "WHERE Id_compteur =... "to take effect before he joined the"diagnosis2"of the table, but do not know how to do.
  
  The subquery takes a lot of time when to return all the lines is "meteoData.
  
  This code is supposed to be a VIEW, so "WHERE Id_compteur =... ' will not be included in it but passed when you query the view. I tested it as a point of VIEW, same problem.

  I hope that my question is not too blurred...

  Ah, sorry, I missed that bit in your original post. I had a similar problem where I was adamant that the predicate must be pushed into the view (despite the use of analytical functions - they used the conditions that would allow the predicate be pushed): http://www.orchestrapit.co.uk/?p=55

  In the end, I solved my problem by using joins to inline, rather than the subquery factoring - maybe you can try to convert your view online views and see if that helps?

• Disable LOGGING for partition table based on the automatic INTERVAL

  Hello
  
  I created a database table of paritioned range interval with NOLOGGING as the default attribute for the table as well as the tablespace definition.
  
  When ORACLE automatically creates a new partition for this table, it activates the LOGGING for this automatic partition even if the table definition says anything else.
  
  How can I go about changing this behavior? Is it still possible?
  
  FYI my platform is 11 GR 1 (11.1.0.7) material on SUN SOLARIS 10 SPARC.
  
  Any help will be appreciated.

  Right, so refer to a new feature of Oracle 11 g partitioning called 'partitioning interval. "

  +"+
  + The interval partitioning: A new strategy of partitioning in Oracle Database 11g, +.
  + Interval partitioning extends the functionality of the method range to define equipartitioned +.
  + ranges using a definition of the interval. Rather than specify individual +.
  + going to explicitly, Oracle will create any partition automatically as needed.
  + every time the data of a partition are inserted for the first time. Interval +.
  + a lot of partitioning improves maneuverability of a partitioned table. For +.
  example, + a partitioned table interval could be set so that Oracle creates a +.

  + in the database. +
  + The techniques available for a partitioned table interval are interval, interval-+.
  + List, range-Hash, and interval range. +
  +"+

  In order to disable interval partitioning on the transactions table, use:
  
  ALTER TABLE transactions SET INTERVAL ();
  

  http://download.Oracle.com/docs/CD/B28359_01/server.111/b32024/part_admin.htm

  Disable partitioning interval on this table, create a procedure to run every day we'll say, to create a new partition and chop the old partition of the appropriate table. I presume that the automatic partitioning interval creates the partition with the logging by default option without checking the parameters in the table. I have seen no information on this in the Oracle documentation.

  Hope that helps.

• Reg: Cardinality Feedback for queries with variable bind

  Hi all

  One of my query (having no bind variables) takes a lot of time (10 minutes) to run for the second run.

  I came to know that its due to the feedback of the cardinality.

  I disabled _optimer_use_feedback for help and the query has been run within 2 seconds.

  If I disable _optimizer_use_feedback at the instance level, is there a problem for queries with variable bind?

  > Sorry! I'm not suppose to disclose the NAMES OF THE TABLES

  OK, no problem and I take this restriction as a chance to learn what is cardinality comments, and similar expressions.  Now, since you can't explain post program for our help, I would try to explain what is comments of cardinality and similar expressions: (since you did not mention Oracle version, so I guess it's 11.2.0.1)

  In the Oracle 11.2.0.1 database some SQL statements returns significantly different lines i.e. for some SQL statements earlier execution plan there are has 100 lines by optimizer in the first plan of execution and, where the same SQL statement executed, based optimizer 1000 lines.  This happens because of several cursors for child for a single SQL statement and change bind peeking, collection of statistics, characteristic of re-optimizing 11.2.0.1, permission to referenced objects, ACS (Adaptive Cursor sharing) etc.  The preaching of changes to lines due to above reasons as well regarding also the SQL statements that are not contains the variable i.e. AKA vibration cardinality of liaison function.

  I will highly recommend to read other links below:

• Partitioning interval. How to choose the name of the partition

  Hi all
  
  Is there a wat to choose the name of the partition when new partitions are created?
  Instead of "SYS_P101", I mean something like CUSTOMRES_P_256, where 256 is the new value that caused the creation of the partition.
  
  The reason is that, before you launch a long process I need to collect statistics on the partition based on this number
  
  Thanks in advance,

  You can rename a partition with your preferred naming convention:

  alter table CUSTOMER rename partition SYS_P101 to CUSTOMRES_P_256;
  

  But you first need to know the name of the partition. One thing I have used in cases when a partition interval has not created yet is to insert a record with the new partition key value so that the partition interval is created, then get the name of the partition and then push the insert. In this way, you know the name of partition before any data is loaded.

  Of course, you can query dba_tab_partitions and examine the high_value column to select the correct partition. However, I prefer the method of obtaining the name of the next partition. It gives you the name of the partition for a row in a table. This is also useful for existing data (not only new partitions) If you need to find the partition where a certain rank.

  select subobject_name
  into v_partition
  from ALL_OBJECTS
  where OWNER = 'SCHEMA_OWNER'
  AND data_object_id in (select dbms_rowid.rowid_object(rowid)
                                   from FACT_TABLE
                                   where PARTITION_KEY_COL = MY_VALUE
                                   and rownum = 1);
  

  You can then use the name of the partition to load your facts, statistics or rename the partition.

  Which must be read carefully. It is said should be "NUMBER or DATE type. Note that 'DATE type' does NOT mean 'Type of DATE data. A TIMESTAMP (but not TIMESTAMP WITH TIMEZONE) are a type of DATE. It's confusing and the doc must could be formulated differently.

  This code is very well:

• modify an existing table to selectively the partition interval range

  I'm using Oracle 11.2.0.3.
  
  I have an existing table that has parition interval range.
  
  example:

   
  create table Log( ts date, level  varchar2(20), scr varchar2(2000))PARTITION BY RANGE (TS)
  INTERVAL( NUMTODSINTERVAL(1,'DAY'))

  Currently, we have the log of the table that is the partition of the range by day and we drop old parition to a week. However, we want to change this to persist the records in the table of WHICH = LEVEL "IMPORTANT."
  
  What is the best way to achieve this?

  >
  Is it possible to modify the existing interval partition table to add partition in the list?
  >
  Only using the DBMS_REDEFINITION to do online. And that always involves the creation of a "provisional" table

  If you have a window of failure just to create a new partitioned table the way you want to and INSERT the data into it. You should be able to use a DEC to do if you want. You may not use swap partition since all data must be physically moved.
  >
  Can we do list-interval partition table i.e. (with partition interval as partition sup)?
  >
  No - subpartitioning of interval is not currently supported.

  Here is the code example of a partitioned table by using the RANGE-interval LIST. It uses a VIRTUAL column, but you can ignore it for your use case

  DROP TABLE mytable;

• Tips on how to make a business case for partitioning

  Hello world
  
  I am the architect of a team of business intelligence/data warehouse. We have grown to the point where I think that we need database partitioning. I believe that we are at approximately 1.5 TB of data. Our larger tables are the counts of 100 million lines with relatively large lengths Records (~ 100 columns). Our just a sort of large tables are of the order of 10 million to 50 million, however, they have very long line lengths (~ 300 columns). Based on the plans of our future source system, our data will become even more granular, and it is always necessary to maintain our historical data.
  
  Those who are not the only reasons, but are some conduct issues that make most of our team members think it's time we purchased database partitioning. Our team is fairly unanimous for partitioning, many of our partners from the source system also deem an 'evidence', however, we get a push back of our CIO saying that 1.5 TB and 100 million records is not only the large amount of data compared to other 'big Data' businesses and that it requires no partitioning.
  
  Anyone has any advice on how to make a business case for the purchase of partitioning? Is there a good way to demonstrate the value of profitability-vs?
  
  Thanks for your comments.

  The best cost c. analysis of benefits is that you put together based on points regardless of the pain you feel.

  For example, you have pain around your evening of meeting load ALS? If you do, you can watch how (and if) partitioning would allow you to streamline your loading process and how much time you would save probably every night. If you have no problem hitting your evening load ALS today, however, this probably isn't something you want to focus on.

  You have pain around query response time? If Yes, you can watch how (and if) partitioning would improve some of the queries and most important reports. Or, perhaps, he would have you to allow users to do an ad hoc analysis more than you can't afford today because the cost would be prohibitive.

  Although you will find no doubt generic cost v. benefit whitepapers, it tends to make a much better case if you focus on what causes the pain of the company and what you as the application developers are willing to commit to. It is easy for a CIO watch a generic white paper saying "partitioning reduces ETL time up to 99%" and the question of what improvements he or she would have actually see and how this is marketing hype. It is much more difficult to look at a document put in place by the data warehouse team saying "partitioning would allow us to reduce the load of X of Y hours on Z hours every night. "That would allow us to hit our SLA w % more often without adding hardware / additional treatment for A project that we have been postpone / let Department B start to work with the data more early every morning / what causes the pain of the IOC. Of course, this means that he must be willing to make such commitments (and, of course, to meet).

  Unfortunately, when we run the query XML is slow; a full table scan occurs on the query and the xmlindex do not get used.
  We are at a lost as to why the xmlindex serves not - before and after collecting pass them on the underlying table for the ACME_CUST?
  Especially with highly selective predicates in the WHERE clause.
  
  
  Here is the definition of table ACME_CUST:

  Could you post an explain plan?

• PC running slow increadibly with 128 MB of RAM - recommended to increase the RAM

  Original title: pc running slow increadibly with 128 MB of RAM

  My mother's PC runs incredibley slowly.
  After you perform a clean installation of win xp and addition of firefox, and avast antivirus, pc still increadibly slow.
  His laptop is a HP Omnibook xe4100 and has 128 MB of ram.
  What I do need to update the ram of the laptop computer or is the problem of something that can be fixed with software recording cleaning?
  Thanks for any help on this!

  If you did a clean install, it is not the registry slow down your computer. A clean installation removes all and back windows on the system with just windows files, so the registry is only what is absolutely need to run.

  128 MB of RAM is incredibly low, so even if the slowness is caused by something else, you should buy more in any case, because it will help the computer a little.

• OKR preserved with the implementation form/partition conversion?

  I am a new owner of an Ideapad S12 - as well as new to this forum, so I apologize if I didn't search well enough, but I could not find explicit answers to what I'm wondering.

  I understand that OneKey Recovery will continue to work as long as the disk partition HARD sizes remain unchanged. But let's OKR also continue working if I format and/or to change the file system, but leave the partitions and partition sizes unchanged? Specifically, I want to maintain the Restore Factory Default option when you press the OKR when arrested.

  Here are the current provision of the HARD drive:

  • Primary partition (C:, FAT32)
  • Extended partition (logical drive D:, NTFS)
  • (Inaccessible from Windows, NTFS) recovery partition

  I am considering the following actions:

  • convert C: from FAT32 to NTFS by using the command line in Windows
  • do a clean install of Windows, C: to NTFS formatting, leaving only the D:
  • do a clean installation of Windows, try to convert an extended in a primary partition partition D:

  I read on the people who make the first action without any problem, but OKR still work? I also have never worked with extended partitions, so I don't even know if the second and third actions are possible, a fortiori if they preserve OKR.

  I was quite surprised that the HARD disk has been partitioned so archaically, with FAT32 and extended partitions. I hope someone can tell me how can I go with formatting without losing the ability to restore my default HARD drive!

  Hello

  There is a big NO...

  Sentence: Small things could change the world... full up here

  ... But a full backup is always the best solution... When you invest a couple of hours after the backup

  You can do what you want... fresh install XP Home or Prof.... or Multiboot... Windows 7... Vista... SnowLeo... anything...

  but when you want to change something on the hard disk before the backup, you are alone in the dark .

  No one could help you easily or, in the case of bad tie...! Its your own risk!

  I prefer once again...

  Without costs high, why not use it... But needs a key-USB-DVD!

  EASEUS to do the backup will do likewise.

  the difference is, you need a CD player to start the rescue media program

  & minimum a 8 GB USB stick / HARD drive for the backupfile... & more time... but it's free...

  If you want to see what can happen Ive wrote a small article in German map S-series, translated by google

  Press F11 for lack of operating system

  Original article in German language, if you can read German

  Not translated Press F11 for lack of operating system

  In short repeat... it's S10e doesn't come with OKR but always symptom even on all S-Series...

  That's what you get after partitioning or re-formatting change

  First look seems OK...

  To start on the rescue and the recovery environment. Press F11

  But when press F11... you got it... uuuppps...

  Missing operating system

  So, what are you waiting for

  Trust people, not machines

• Time of very slow start with SSD

  Hello

  I spent the last few days the net trying to find a solution to the boot of win7 very slow but have led to nothing so far trawling.
  Im running Win7 Pro in bootcamp on a Macbook Pro with an SSD and 16 GB of RAM, but don't get a time horribly slow start, including a screen black (with usable mouse) for a long time before the watch office. I am not able to do a reinstall but would like to get the issue resolved if possible.

  So far, I checked the event viewer to see there are problems and I don't see anything significant that the mere fact that each entry includes an 'Error' level, but I don't see what this error. I also used the process monitor to see what takes so long and there are a couple of processes which are time consuming and show a result 'Cancelled', one being svchost.exe 110secs (path: ...system32\drivers\etc) and the other 23secs Explorer.exe (path: ...appdata\roaming\microsoft\systemcertificates\my)

  I should mention that I'm very new to this kind of troubleshooting but would appreciate any help I can get!

  Thank you!

  The problem is that windows has been hanged in trying to restore network connections. Problem solved!

• Slow WiFi with Broadcom 4322

  After upgrading my laptop HP DV7 with Windows 8, I found my wireless connection was extremely slow. My card is a Broadcom 4322AG. This seems to be the same problem as has been in the forum

  
  Slow WiFi with Broadcom 4322 and Windows 8 CP.

  Following the advice in this forum, I changed to TKIP AES security and everything seems to work properly.

  Thanks a lot for sharing your solution! My problem was that I downloaded at least 1 Mbit/s and transferred approximately 15 Mbps. Then I changed to TKIP, just as you said and now I'm moving 21 Mbps of download and 19 Mbps downloading. All this on a MacBook 5.1 :)
