Weird performance in a guest VM problem

• Weird Performance problem

  Hi all

  11.2.0.1

  AIX 6.1

  We have 2 servers of db (TEST, PROD).

  Then we have an app1.exe that runs well in PROD, but works poorly in TEST, in the sense that it made full in TEST table scan, it does scan small index in PROD.

  The SQL sample problem and is captured by the report of ASHES is like this:

  Select empid, empname, salary from EMP where empid =: 1 FOR the UPDATE.

  
  

  I tried to explain the plan of the query on Server TEST, PROD and they use the index, which means they have the same execution plan.

  Can you give me a idea why when app1.exe is run on the TEST, it uses a full table scan? or different execution plan against PROD?

  TEST a Database Vault & TDE (transparent data encryption) installed, but I don't think that he is the culprit?

  Thank you very much

  in many cases, the auto_sample_size should be almost as good as 100%: http://structureddata.org/2007/09/17/oracle-11g-enhancements-to-dbms_stats/. One of the cases where auto_sample_size is not good is creation histogram.

• Performance of OBIEE report initialization problem

  Hi all:
  
  Thanks for reading this first, please forgive a few appropriate words, I'm not good in English...
  
  I encountered a problem on the production, when the report is selected, it appears very slow even I made a few adjustments of performance on this report. And after I checked the session, when the report is selected, it works again with some WHAT SQL with each guest has value and it doesn't show any results in the present report.
  
  So, my question is, is it possible to not run this SQL or y at - it another way to better performance on this report?
  
  Thanks for answering that.

  I certainly have a lot of suggestions. But to really help, I need a little more detail.

  How different measures do you have in the pivot table? You have all time series analytics in there (as there is or far)? Approximately how many records are displayed in the PivotTable (100, 1,000,100,000)?

  More important still, you followed its use is enabled? If this isn't the case, please turn it on. Blog of John Minkjan here can help you activate it. [http://obiee101.blogspot.com/2008/08/obiee-setting-up-usage-tracking.html]

  If you manage to turn on tracking usage, we can see how much time is spent in the database compared to OBIEE. If it turns out that the bottleneck is the database, then you will need to work with your DBA to set up the database.

• Performance wireless on Satellite P200 problem

  Hello world

  I decided to join this community because I'm looking to solve a pb on my WiFi connection.
  Last week, I bought a Satellite P200.
  OS: Vista
  Wireless LAN: Atheros AR5007EG

  Everything works, but I have a performance problem with the connection.

  This computer is connected to a network of personnel via a linksys WRT54G.
  I have 3 computers (Medion desktop plus 2 other laptops). These 3 computers remains stuck between 3 (WiFi) and 4 (ethernet) Mbit/s on the internet connection.

  The Toshiba receives between 300 and 500 Kbps. It is also very long to detect my network.
  If I connect it by Ethernet: 4 Mbps

  Here is a list of different things I tested:
  -updated drivers
  -test without any key secure over Wifi (WPA - PSK)
  -disconnect avast (or Norton)
  -change the MTU
  -Try a netsh command
  -change of frequency of the signal.

  All ping tests are perfect: it gives exactly the same results as the Ethernet connection. the pb happens only on internet surfing.
  I also try the recovery but the pb is already there when I bought it.

  If someone has a new idea or a trial, it will be great.
  Thank for your attention and sorry for my English (I don't practice for a long time: o)))

  I know Vista's problems if you use the WiFi network.
  This Microsoft article describes the various problems and provides the patch.

  The issue I'm having is on the slopes significantly slower than #2 #1 VM.  #2 works pretty decently.  #1... well over this long last week I started it after being unused for awhile.  I got the prompt to install VMTools so I did this. He took over 36 hours to install VMTools!  ;-((.  I want to update the operating system with updates from MS since several months, but I did not "months (or more!" to run through the update.

  What are the options (performance etc.) would you suggest for #1?  Apparently, the two #1 and #2 are the same, as far as I KNOW, in all other aspects of the guest operating system and settings.  Is there a setting/performance video or paper about this game and how build/debugging etc. for optimal performance?

  TIA!

  Hello.

  How did they build each of these virtual machines out there?

  #1 is slow if #2 is also well off?

  Good luck!

• SuSE Linux ARE 9 guest - installation problem

  Hi all

  under VMware 2.0.0 WinServber 2003, I tried to install SuSE Linux Enterprise Server as a guest operating system. But she didn't in this sense, I'm not able to read the contents of the console remotely.

  After that turn on/off the normal startup innstallationnprocess, but after passing all the tasks of detecting screen spit upward into two and one can only imagine that the last line says "from Yast"

  I tried to start the installation with another resolution, but has no - installation always splits the screen and you have two unreadable screens with mediocre colors (somehow amber "retarded") in the 2/3 of the top and bottom you have the typical SuSE.

  Any help or info how to make it useful to install SLES9 is welcome.

  Thank you and br

• Q10 guest - zone problem blackBerry calendar event

  Hi all!

  I've just switched back to BlackBerry, iPhone and love everything about it so far except for one thing: calls on the calendar time zone problems.

  My work using an OS X hosted the CalDAV server, and I was able to sync my existing calendars to it without problem.

  My timezone: Eastern

  My colleagues timezone: Central

  Question: I received an invitation from a colleague, and on my Mac, it shows 13:00 Eastern, as it should.  The invitation has been sent to 12:00 Central.  This same invitation appears on my BlackBerry at 07:00 Eastern.

  Completed test:

  I added an invitation on my BlackBerry at 06:00 Eastern as a test and it appeared on my Mac at the right time without problem.

  I added an event on another day of my Mac, and it synced to my BlackBerry without problem.

  So it seems that my problem is that when the receiver event invites others, possibly in different time zones.

  My Mac and BlackBerry are both set to the Eastern time.

  My co-workers Mac and iPhone are set to Central time.

  I looked at all the parameters BB and can't find anything that would explain this strange behavior.

  I tried a battery pull - same results.

  I'm on the latest OS available for a Q10: 10.2.1.2976

  Can anyone help with this?  I'd hate to go back to iOS for a question like this, however, a precise and reliable timetable is essential for my work.

  Another update:

  Only, the lady came back on the line and told me that it is a known problem that is "actively investigated."  When asked how long their ticket has been opened on this subject, I was told since September of 2013...

  It seems that there is no resolution for this problem.  I will go back to iOS

• Performance in ODI 11 g problem

  Hello world

  I created an interface, where source has 2 has no records and I used the incremental update of Oracle IKM.

  When I ran at full load it loads data into the target in a few minutes.

  When I ran the next day to delta load taking 1 hour for load data into the target.

  How to solve this problem please help me.

  Hello.

  There are a few things that you can play around incremental IKM to tweak it to make it run faster...

  * The first thing you will need to manually identify which generates ODI as sql code. If you don't like or don't know, then next step is to look at a few option that you can change to IKM level.

  The underside of my discoveries... in order to choose who should be.

  Solution 1: The best approach is to CDC, but I say again, I use the Golden gate for CDC + ODI for normal load combination (but you must have additional licenses for goldengate)

  Solution 2: Always check your value for the option of screening strategy, if you see a NOT EXISTS clause in sql generated by ODI, then better change detection at LEAST stragety. It will be faster to NOT exist.

  Work around 3: understand actuall incremental update, it will check all the lines from the source to target based on PK which is defined on the data store target, some of the IKM do it line by line, some of them by Setbased.

  so try to put the detection strategy option in an incremental update IKM votes to ZERO and then try... This means that... ODI will now try NOT to compare source and target again data for those rows that are already in the target...

  Knit approximately 4: try incremental update of revenge (FUSION) instead of the IKM incremtal update, as merge IKM will be club all operations update/insert in a single step, but not the same case in incremental update IKM.

  Hope this helps

• Effect weird transition in first pro 2015 problem

  As the title says I have a very strange problem. When I try to apply a transition between two cuts effect the transition begins to add some additional images that are not in the full video completely or one of the videos together. I know that because I deleted these same images when I started to edit at the beginning. Ill post a picture of example below and if anyone knows what it is I'll be most grateful to be helped!

  1st photo is at the beginning of the transition, and as you can see it the African woman is not supposed to be there and some pictures later, she disappears and the next video begins (which isn't supposed to to happen at all).

• Connect to the Oracle database on a guest VM - problem

  Hi all
  
  I was faced with a problem with my Oracle VM. Let me explain:
  
  I have a virtual machine running CentOS 6 with Oracle Database 11 g 11.2.0 installed. I want to do is use SQL Developer, Toad, SQL * PLUS the host machine that is running Windows 7 64 bit.
  The virtual machine uses a host-only adapter network connection and a bridged adapter (for when I need to use internet in the box).
  Here's the question, I can ping the virtual machine to the host without problem and also I can ping the host of the virtual machine. But I can't do tnsping between the host and the VM.
  
  Listening port is configured as a default (port 1521) and the tnsnames.ora in hospitality is OK, but when I tnsping it I get messages from downtime.
  
  Is this something related to the network between the host and the VM? Can someone seated?
  Please let me know if you need more information on.
  
  Thanks in advance.

• install ESX/ESXi on faster disks increases performance of the guest OS?

  for example, if you have installed ESX/ESXi on a faster local SSD or HARD disk, would be the overall performance of the ESXi and hosted OS be improved?

  Or ESX works completely in memory even after the start, so it does not improve a lot?

  If you have an iSCSI storage, I suggest you install ESX (i) on the local disk and attach (s) your storage iSCSI LUN as a VMFS data warehouses.

• Problems of performance of Premiere Pro, no problem with AE

  Hello

  Recently, when I use Premiere Pro, I seem to have big problems. It runs really slowly, the preview always stutters and some projects with many files imported not even loading. I thought it was my computer die, until I started to After Effects. I thought that After Effects is a much more difficult program for my computer to manipulate than Premiere Pro, but it works quite normal.

  Recently, my laptop has been too hot a lot of times, especially when using Premiere Pro. It automatically shuts off safety. Perhaps because he was running this program, some of the files I messed up because of the heat?

  Is there anyone who knows if it's my problem or if there is another problem that I don't see?

  Many thanks in advance!

  4 GB is really not enough.  I sometimes struggle with 24 GB.

  If you do not intend crop your pix, 5000 x 3500 are great - and the fact that they are 9 mb probably contributes to the problem.  Strip unnecessary pixels - which makes the 72 dpi image.  Which will reduce your pix to about 2-3 MB each.   Reduce them to 1920 x 1080 (if you are not pan and scan)

  You probably also have problems with hard drives.  C is going to be difficult to store temporary files with only 9 GB of available.  Similarly, the D is a tad grating.  Are these disks 7200 RPM?

• Flashback data archive commit the performance of time - a bug problem?

  Hi all
  
  I use the Oracle 11 g R2 on 64-bit windows environment. I just want to do some tests quue flashback data archive. I created one and add to a table. about 1.8 million records is to exist in this table. Furthermore, this table is one of the examples of oracle, SH. SALEStables. I created another table using the table and insert the same data twice.
  

  -- not a SH session
  
  Create Table Sales as select * from sh.sales;
  
  insert into sales select * from sh.sales;
  Commit;

  insert operation takes a few seconds. sometimes, in this code, validation command takes more of * 20 *, sometimes 0 seconds. If validation time is brief after insert, can I update the table and then validate again:
  

  update sales set prod_id = prod_id; -- update with same data
  commit;

  update takes a few seconds longer. If the first commit (after integration) has had too little time, second validation, after the update, takes more than 20 minutes. At this time, while that commit were working, my cpu becomes overloaded, 100% charge.
  
  the system that oracle runs on is good for quest staff use, i7 4 real core cpu, 8 GB ram, disk SSD etc.
  
  When I looked at the Business Manager - performance monitoring, I saw this SQL in my sql album list:
  

  insert /*+ append */ into SYS_MFBA_NHIST_74847  select /*+ leading(r) 
           use_nl(v)  PARALLEL(r,DEFAULT) PARALLEL(v,DEFAULT)  */ v.ROWID "RID", 
           v.VERSIONS_STARTSCN "STARTSCN",  v.VERSIONS_ENDSCN "ENDSCN", 
           v.VERSIONS_XID "XID" ,v.VERSIONS_OPERATION "OPERATION",  v.PROD_ID 
           "PROD_ID",  v.CUST_ID "CUST_ID",  v.TIME_ID "TIME_ID",  v.CHANNEL_ID 
           "CHANNEL_ID",  v.PROMO_ID "PROMO_ID",  v.QUANTITY_SOLD 
           "QUANTITY_SOLD",  v.AMOUNT_SOLD "AMOUNT_SOLD"  from SYS_MFBA_NROW r, 
           SYS.SALES versions between SCN :1 and MAXVALUE v where v.ROWID = 
           r.rid

  This consumes my resources for more than 20 minutes. what I do is, just an update 1.8 milion records (which use update is really takes little time) and validation (which kills my system).
  
  What is the reason for this?
  
  Info:

  Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
  PL/SQL Release 11.2.0.1.0 - Production
  CORE    11.2.0.1.0      Production
  TNS for 64-bit Windows: Version 11.2.0.1.0 - Production
  NLSRTL Version 11.2.0.1.0 - Production

  I see that in the example of Guy Harrison the SYS_MFBA_NROW table contains a very large number of lines - and the query is forced into a loop of neste join on this table (as is your query). In your case the nested loop is a vision (and there is no sign of a current "pushed" predicate.

  If you have a very large number of rows in the table, the resulting code is bound to be slow. To check, I suggest your run the test again (from scratch) with active sql_trace or statistics_level defined at all so that you can get the rowsource for the query execution statistics and check where the time is being spent and where the volume is displayed. You will have to call this one in Oracle - if this observation is correct that FBDA is only for OLTP systems, no DSS or DW.
