Potential problem of Volume

• Potential problems with copy_table_stats.

  Guys,

  I have a table with the DDL below containing a huge number of records.

  CREATE TABLE APPEAL. CALL_DTL

  (

  DATE TIME STAMP,

  MSN VARCHAR2 (32 BYTE) NOT NULL,

  EVENT DATE NOT NULL,

  )

  PARTITION BY RANGE (EVENT)

  (

  CALL_P_01122015 PARTITION VALUES LESS THAN (TO_DATE (' 2015-12-01 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN ')),

  CALL_P_02122015 PARTITION VALUES LESS THAN (TO_DATE (' 2015-12-02 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN '))

  CALL_P_03122015 PARTITION VALUES LESS THAN (TO_DATE (' 2015-12-03 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN '))

  );

  We collect statistics for the 1st of the score of the month.

  BEGIN

  DBMS_STATS.gather_table_stats)

  ownname = > 'CALL. "

  tabname = > 'CALL_DTL ',.

  partName = > "CALL_P_01122015"

  estimate_percent = > 1,

  GRANULARITY = > 'APPROX_GLOBAL AND PARTITION,

  Cascade = > TRUE,

  degree = > 15);

  END;

  /

  And the stats will be copied in the rest of the partitions of the month.

  Start

  DBMS_STATS.copy_table_stats (ownname = > 'CALL')

  tabname = > 'PMS_CALL_DETAIL ',.

  srcpartname = > 'CALL_P_01122015 ',.

  dstpartname = > 'CALL_P_02122015');

  end;

  /

  Start

  DBMS_STATS.copy_table_stats (ownname = > 'CALL')

  tabname = > 'PMS_CALL_DETAIL ',.

  srcpartname = > 'CALL_P_01122015 ',.

  dstpartname = > 'CALL_P_03122015');

  end;

  /

  Start

  DBMS_STATS.copy_table_stats (ownname = > 'CALL')

  tabname = > 'PMS_CALL_DETAIL ',.

  srcpartname = > 'CALL_P_01122015 ',.

  dstpartname = > 'CALL_P_04122015');

  end;

  /

  ...

  ...

  Could someone advise if there could be potential problems with the copy of his stats?

  What I see, HIGH_VALUE and LOW_VALUE are the same for every single partition for the SQL below:

  Select nom_partition, HIGH_VALUE, LOW_VALUE from dba_part_col_statistics where table_name = column_name 'CALL' IN ("MSN");

  
  

  Will this result in CBO plan fetching suboptimal on SQL running on the table with predicate such as MSN and EVENT?

  Please suggest me resolution approaches.
  

  
  

  Thank you!!

  It will depend on (among other things), how use you it as a predicate and unique how the column is.

  If you try to filter using predicates of beach in function with a range outside the stats then the CBO will be predicate weak cardinalities and therefore will promote the access of the index and nested loops which leads to this.

  If you are filtering on equality predicates and the key is unique there should be no problem really.

  It will depend also on whether the request knows which partition will be scanned, otherwise it will use global statistics, which will be probably the same as a partition, but they could easily change if you were to collect stats on any other partition.

  You have an environment you can use a test and see approach?

• Potential problems for tables without primary keys and unique keys

  GoldenGate 11.2.1.0.3/Solaris 10
  DB: Oracle for Oracle (Source and target is 11.2.0.3)
  Topology: unidirectional
  
  
  In our one-way configuration GG, little of the tables being replicated is not a primary key or a Unique key.
  
  Last week when we have implemented GG for the test, we received warnings for these table below.
  

  GGSCI > add trandata WMHS_UD.crtn_dtl
  
  2013-01-12 11:34:33  WARNING OGG-00869  No unique key is defined for table 'CRTN_DTL'. All viable columns will be used to represent the key, but may not guarantee uniqueness.  KEYCOLS may be used to define the key.
  
  Logging of supplemental redo data enabled for table WMHS_UD.crtn_dtl.

  Replication seems to work very well for these tables.
  
  Googling, I think that there may be performance degradation when you replicate tables without PK or the United Kingdom.
  
  But are there other potential problems such as data of a certain kind not replicated to the lack of PK/UK?

  It really depends on the data.

  By default, GG is combining all columns as a virtual primary key but don't no conflict control by default. So when you can be sure that the record you insert into the table is unique, then it will work.
  BUT as soon as you insert the same record, which is already inserted, then you will encounter problems.

  Let me show what happens when you use an initial charge because it makes it easier to describe:
  We start at 10:00 the capture for a table. Now, you insert a record at 10:00 in the tables. When you now start an initial charge to 10.02, then check you have inserted in the database to 10.01 will be repeated two times. During the IPL as the initial charge is made to 10.02 and it includes data of 10.01 AND it will be replicated again through the process of capture/replicate.

• Potential problems with access to 10g EUL with 4i discoverer desktop?

  Hi all
  
  We have recently upgraded to Discoverer 10 g of 4i and still have a number of computers of the users with the old 4i desktop client. They have the ability to access the 10g EUL using the 4i client and I would like to know of any potential problem with them doing so.
  
  Thanks in advance, and any comments would be greatly appreciated.

  Hello
  A 4i Desktop cannot access a 10g EUL. When you did the upgrade you probably enriched by using the same schema, alias name of EUL.

  What's happened is that Discoverer 10 g installed a brand new 10g EUL in the same schema. 10 GB objects that all start with EUL5, the discoverer 4i objects while all begin with EUL4. The upgrade was non-destructive, which means that your old 4i posts clients and Desktop 10g clients can coexist, however they not have access the EUL even. 4i clients will connect to the old discoverer EUL 4 and your new or those connecting through a URL, will be connected to the 10g EUL. Any changes made in one as all new workbooks will not appear in the other.

  If you are satisfied with the upgrade, you must install Discoverer 10 g Desktop on any machine that still has access by computer, and then remove the installation 4i. If you want everyone to use a browser to connect you need to uninstall all versions of office 4i.

  In addition, if you have many versions of office you use is no longer, you should ask your Oracle sales representative if they will convert these licenses in other licenses for you. You paid good money for them and they are still valid as long that you have to pay the annual maintenance and support. Some sales representatives do not realize that it can be done.

  Hope this helps explain

• Problem of volume with Satellite Pro L630

  Hello
  Brand new on these forums so forgive me if I am in the wrong part of the forum.
  My L630 bought 19 November 2011, and has downgraded the OS XP Pro. Problems with the volume that is barely audible when full! Is there than some tweak I can do to improve the volume?
  Thanks heaps...
  Murphy

  Hello

  You can try to adjust the volume to a higher level.

  Go to control panel of control-> sound, speech and audio devices-> sounds and Audio devices

  Now, go to the Audio tab (line from the top of the buttons) and in reading his article click the Volume button.
  In the Volume Control Panel, click the Options menu button and choose Properties.

  In the properties panel check all the boxes unchecked.
  Now you should see all the volume controls which could be addressed at the next level.

• G20 - problems with volume wheel

  My volume wheel does not work as it should, when I'm trying to turn down the volume, he jumps again. even when turning upward, it's the jump down. Put upwards or downwards to turn and turn and turn until it moves. If I fire the sound upward is like it is move 1 up, 1 down, 1 up, 1 down, 2 up, 1 down... and so on.
  Does anyone have a solution for this problem? It's like that in the Qosmio player and Windows.

  Truls

  Hi Truls

  It's very strange question. I too have the Qosmio G20, but have no problem like this.
  This problem occurs only if you use the wheel of volume on the right side or the same thing will happen if you change the volume using Volume control tool?

• Satellite Pro P300 - problem with volume control

  Hello

  I have a problem with my volume control. He worked for the first two months of use value, but now refuses to lower the sound.
  He sort of stutters and actually transforms the sound upward when you turn, he 'left' to drop.

  I markets DEAMS it is a digital control and therefore is not a point 'end' like other laptops. I also noticed others are experieicing this problem.

  Is there a solution to this problem? I don't really like having to manually click on the volume control in the status bar on the window in order to be able to turn the laptop down. Maybe someone can help me?

  Thanks in advance.
  Sam

  Hello

  In your case, I recommend reinstalling the audio driver and controls (with Win XP) Toshiba or Toshiba VAP (if Vista is installed).
  In addition, you should check if the BIOS can be updated too.

  Sorry for this suggestion, but in my opinion that the question must be related software and the fact is that driver sound and the VAP multimedia button controls and the sound card.

  It of certainly worth a try

• Headphone and speaker volume problem. Volume is not stored.

  I have the Helix i5 and the problem I have is that when I plug in my headphones, the volume does not automatically adjust. If my speakers are at full volume, so are my helmet when I plug them in. Please help me solve this problem. My Microsoft Surface never had a ridiculous topic like this.

  On the top right side, press "Device avancΘs".

  Choose mode multistreaming

  For me this unlocked separate volume sliders to the speakers and headphones

• Problem strange volume with OS 7.1 MP3 playback

  Hi all

  I'm having a strange problem when playing an MP3 of my application.

  I use javax.microedition.media.player class, and I know it sounds weird, but after reading the his 25 times the volume becomes weaker.

  The application is compiled with version 5.0 of JDE and works without problems on all devices except those with OS version 7.1.

  I tested in a 9900 a 9860 and a 9810 with OS 7.0 and 7.1, and only detected this problem when this last operation, so I think that not is a code related issue.

  Also, I tried to recompile the application with JDE 7.1, but makes no difference.

  Even I put the volume level whenever the sound is played:

      public boolean play(String fnm, boolean isLoop)
      {
          if (!isDeviceAvailable) {
              return false;
          }
  
          Player player = (Player) soundsMap.get(fnm);
          if (player == null) {
              return false;
          }
  
          if (player.getState() == Player.STARTED){
              return true;
          }
  
          try {
              if (isLoop)
                  player.setLoopCount(-1);
              VolumeControl volumeControl = (VolumeControl) player.getControl("VolumeControl");
              volumeControl.setLevel(volumeLevel);
              player.setMediaTime(-1);
              player.start();
              return true;
          }
          catch(Exception e)
          { System.out.println("Could not play " + fnm);
          return false;
          }
      }
  

  All the world has noticed this same problem with any of your applications?

  I finally managed to find the problem.

  When you have more than one player loaded in memory appears this extrange with volume behavior.

  As I say this happens with OS 7.1

  If anyone is interested, this simple application to reproduce the behavior. Simply load two mp3 files and let them sound, until you enjoy a change in volume (not over 25 or 30 loops in my case)

  As you can see, only the second player is started...

• Problems with volume on a Windows 7 laptop

  Hi, I have a laptop with windows 7 installed and I have a problem with my volume control.

  My volume control acts as if someone or something has been pressed. For example I click on the icon to open the volume control and it shows that the volume is down. When I click and try to drag the control to the top, it will go up but immediately down as if someone he had the opposite effect. I tried to fix this on my computer nothing works. I tried to see if it has changed when I plugged my headphones but I always had the same problem. Open the volume mixer or enter the system of sounds does nothing either. I was wondering if anyone has had this problem before? I have never seen anything like this myself.

  See you soon.

  Have a read of this (rather long) post of similar sounding and see if the work of suggested corrections - http://answers.microsoft.com/en-us/windows/forum/windows_7-pictures/my-volume-slider-under-windows-7-keeps-going-down/2769853f-e412-4c4d-8b55-6885588a528f as some of the mentioned patches seem to have helped others. It seems quite a few possible interactions of audio RealTek to Audacity to Skype Manager, etc. and their related settings.

  Hope this helps, if not, I'm sure that someone will bring a possible solution.

• Problem with volume control options.

  Recently, I accidentally deleted everything on my laptop and had to have installed new drivers. Everything works OK except for one thing - volume command on the keyboard when the headset is connected does not work. When he has no headphones plugged and play music out loud, I can control the volume by pressing Fn + F11/F12 and volume is actually change, but with headphones the animation on screen shows the volume "evolves" but it does not really change, I have to do it manually. I have ux32a of Asus, Windows 7, 64-bit, and I don't know which driver should I download to make it work. I hope at least someone understands this problem because I am desperate. Thanks for any help.

  I go on the Web from Asus site, go to the driver download section, choose your phone model and then download the audio driver, it provides.

• If I delete the backup of the Service Pack files to create more disk space, I have created a potential problem?

  Periodically, I use Disk Cleanup to create more space and speed up the startup time. Today when my computer is on, it took an extra long time but when I ran disk cleanup, the amount of space to win does not jive with the time it took to load. Then I pulled the top "Clean up System Files" and cleaning the my backup files of the Service Pack, I have everything to gain from 920 MB of space.

  Question: If I delete those, am I causing potential damage to my system?
  Thank you.
