• How ORA_HASH can improve performance?

  I want to know how ORA_HASH can improve performance.

  Thanks in advance

  Not sure I understand what you want.

  ORA_HASH is just a function of Oracle (often used for the sample data by providing a hash value).

  It's nothing to do with the performance as such.

• Improved performance in vCenter

  Hello all - I hope that the community can help out me with this one.  It is related to the performance of vCenter.

  VirtualCenter arrived at the point where it's VERY slow almost all the time and I cannot understand why.  As examples, in the computers view models, and virtual VC locks up often for anywhere from 20 to 60 seconds, just by selecting one data center to another.  RVTools almost 20 minutes to come.  Also, if I try to install VeeamONE or VeeamBackup, they are slow slow is not usable and sometimes lower VC (so Veeam is not running - I just wanted to give an example).  Finally, if I restart the server (VM) VirtualCenter, it can sit to 'Apply the settings of the computer' for about 20 minutes.

  I support a vSphere environment that consists of the following

  vCenter: 5.0 Update 1 - running on a virtual of Win2k8R2 computer with 8vCPUs and 20 GB of memory

  SQL Server VC: 2008R2 SQL - running on a VM Win2k8R2 with 8vCPUs and 32 GB of memory

  MUV: VM dedicated

  VC Web: VM dedicated

  * The four run VMs on a dedicated Cluster 2 nodes 'management' which consist of two HP DL380p G8s DualProcs & a lot of memory. No other virtual machines running on the host & loans are all practically zero.

  He currently manages 316 ESXi hosts (all 5.0 Update 1) and about 6000 virtual machines.  When VC was installed, I chose the "Large" scale that we will add more than about 200 guests & about 1000 VMs more next year.  The use of the Cisco Nexus1000v ESXi hosts (excluding the 2 cluster nodes mgmt - those that are on the standard vswitches).

  The hosts and virtual machines are in data centers about 20 & 30 clusters, physically dispersed across the country (US).

  Any thoughts on how to make it better?

  Thanks in advance!

  From there, should I run the script to purge old data from the other KB, or should I expect to see improved performance immediately?

  Yes, but... To do the purge your vCenter Server Service must be stopped.  Always better this offline.  We usually do maintenance on our vCenter DB about each quarter.

• How views can improve performance

  Hello

  Can someone explain to me how the views can improve the performance

  When DMLoperations perform through VIEW rather than perform DML operations by table.

  Thank you and best regards,

  Ibrahim Sayyed.

  Hi Ibrahim.

  A view is not much more than a macro which is developed by the SQL engine when running. Generally speaking, views will not improve performance.

  You can take the help of INDEXED VIEWS to improve performance. Then, views have clustered index assigned and, when they do, they will store the temporary results that can speed up queries that result. These views can speed up and simplify the application design.

  What is the INDEXED VIEWS?

• improve performance on WHERE "ABCDEFGHIJK" AS FIELD | '%'

  Hi all
  
  I have several tables with a constant number of cases (between 1000 and 1 million) and an indexed field (usually a primary key) I need mark from a PL/SQL function. The database is 11.2.0.2.0 on RedHat.
  To make it simple guess this:

  CREATE TABLE A (A VARCHAR2(20) CONSTRAINT A_PKEY PRIMARY KEY);
  INSERT INTO A VALUES ('ABCD');
  INSERT INTO A VALUES ('ABCDEF');
  INSERT INTO A VALUES ('ABCDEFG');
  INSERT INTO A VALUES ('ABCDEFGH');
  INSERT INTO A VALUES ('AACDE');
  INSERT INTO A VALUES ('AACDEFG');
  INSERT INTO A VALUES ('AACCDDD');
  -- between 1000 and 1 million inserts
  COMMIT;
  ANALYZE TABLE A COMPUTE STATISTICS;

  I need the file with the longest field value corresponding to the front of a particular value, for example "ABCDEFGHIJKLMN". The correct result is 'ABCDEFGH '.
  A simple solution is this:

  SELECT * FROM (
    SELECT * FROM A WHERE 'ABCDEFGHIJKLMN' LIKE A || '%' ORDER BY LENGTH(A) DESC
  ) WHERE ROWNUM = 1;

  The problem is that the DB is not efficiently using the index (EXPLAIN the PLAN said Index Full Table Scan or Full Table Scan).
  My real solution is to query from the longest possible values:

  DECLARE
     RESULT VARCHAR(20);
  BEGIN   
  FOR LEN_PREFIX IN REVERSE 4..LENGTH('ABCDEFGHIJKLMN') LOOP
      BEGIN
          SELECT A INTO RESULT FROM A WHERE A=SUBSTR('ABCDEFGHIJKLMN',1,LEN_PREFIX);
          EXIT;
      EXCEPTION        
          WHEN NO_DATA_FOUND THEN
              RESULT := NULL;
      END;
  END LOOP;
  -- Do something with RESULT (it can be NULL too)
  DBMS_OUTPUT.PUT_LINE('RESULT: ' || RESULT);
  END;

  Is to use the primary key well and the query is compiled (not dynamic, it is located in a Package + PL/SQL function).
  What I don't like is that I'm running several queries (end with one exception) before obtaining the final result of "ABCDEFGH".
  Since I was 50 million to different values of 'ABCDEFGHIJKLMN', to the query it is increase the number of queries per about 5 times (or more)!
  
  Perhaps another simple solution is to place all the values in a list and then apply the ORDER BY to get the longest value:

  SELECT MAX(A) KEEP (DENSE_RANK LAST ORDER BY LENGTH(A)) FROM A
  WHERE A IN ('ABCDEFGHIJKLMN', 'ABCDEFGHIJKLM', 'ABCDEFGHIJKL', ... , 'ABCD');

  Explain the Plan said SORTING (ITERATOR INLIST (INDEX UNIQUE SCAN))).
  Because I want a compiled query I need to replace this list in a nested table or other objects (not sure which is better).
  But this solution has the disadvantage that any Oracle internally makes a query for each possible value such as the explain Plan tells me. While with the LOOP FOR that above, I'm from the longest to the first found value.
  
  Here's the code using a nested table:

  CREATE TYPE A_TABLE_TYPE IS TABLE OF VARCHAR2(20);
  /
  DECLARE 
       ALIST A_TABLE_TYPE := A_TABLE_TYPE();
       RESULT VARCHAR(20);
  BEGIN
  FOR LEN_PREFIX IN 4..LENGTH('ABCDEFGHIJKLMN') LOOP
      ALIST.EXTEND;
      ALIST(LEN_PREFIX-3) := SUBSTR('ABCDEFGHIJKLMN',1,LEN_PREFIX);
  END LOOP;
  SELECT MAX(A) KEEP (DENSE_RANK LAST ORDER BY LENGTH(A)) INTO RESULT FROM A
  WHERE A IN (SELECT * FROM TABLE(ALIST));
  -- Do something with RESULT 
  DBMS_OUTPUT.PUT_LINE('RESULT: ' || RESULT);
  END;

  I don't know if a nested query is preferred instead of the DENSE_RANK (I need other fields in the record).

  SELECT * FROM (
    SELECT * FROM A WHERE A IN (SELECT * FROM TABLE(ALIST))) ORDER BY LENGTH(A) DESC
  ) WHERE ROWNUM=1;

  Can I add fields, indexes, or whatever is needed to improve performance. Not sure if a partition is useful since they are small tables in any case (although with the number of records).
  
  Any help is welcome,

• ReceiverThreads JMS connector in 10.1.3.3 layout to improve performance?

  Gurus,
  
  I use nonBlockingInvoke = true property in bpel.xml to spawn a thread for each parallel flow activity.
  
  However, the definition of this property I found success in performance. I suspect that the parameter of ReceiverThreads to be the question JMS connector. If ReceiverThreads more could hear in the queue, you can improve performance. (Page 47 of the 10.1.3.1. Performance Document).
  
  But I'm not able to locate this property in orion-ejb - jar.Xml. This property holds a different file or this property needs to be added (please can you provide the exact code)?
  
  Thanks a ton!
  SP

  You can find the documentation of ReceiverThreads here:
  http://download.Oracle.com/docs/CD/B32110_01/Web.1013/b28958/JMS.htm
  (Table 4 - 11).
  There is above the table of examples that show how to add a property.
  (A property can be added to orion-ejb-jar. XML or ejb - jar. Good XML if you set the property via a file .xml orion-ejb - jar.xml is recommended because it is a specific OC4J parameter).

  Alternatively, you can set via the annotation. See here:

• How can I improve performance Adobe CS5?

  I got a trial of Adobe Creative Suite 5 on a PC at work and so far it's ok, but it's really trolling. The PC currently has an Intel Core 2 Quad Q9400 2.66 GHz, 4 GB of Ram DDR2, 160 GB HDD, and an integrated Intel graphics chip.

  Add a dedicated graphics card will improve performance of CS5? I read on the forums that Mac users use a 2nd hard drive as a "scratch disk" for the likes of photoshop which improves performance but do not know how to implement that.

  Any ideas would be great.

  The integrated graphics may well take all system RAM. In addition, you enter your operating system but I recommend Win 7 64 bit with a boat load of RAM.

  Fast hard drives with a drive of dedicated work will help, too.

• Super Proxy? Improve performance more?

  http://help.Adobe.com/en_US/AfterEffects/9.0/WSF13D6BED-c53b-408a-B2D6-C8B4205D4FB7a.html

  Apart from these tips from Adobe on improving performance, does anyone know any other tips?... even if it is a purchase of third party. It seemed that just when mandated, the machine still flat enough to annoy me and theyre proxy/lowres images is of course a bit blurry. I guess Im hoping there are some great plugin proxy that allows you to work superfast. The dream is to create animations 3D HD on a laptop. FTP then all in a cluster, and they do most of the work and send me a nice shiny bluray.

  No, sorry. There is no magic recipe. Computational mathematics defeated this dream. AE is a full buffer rendering engine, which means that everything that this process must adapts perfectly to the RAM. So, if your machine is not at the height - well, you know the story. That will change only when AE Gets a converter in mosaic or a user-friendly method to same memory or knows how to deal with a lot more RAM in a 64-bit version. So far, these solutions will have to get by.

• Improved performance for EBS

  Hi all
  
  We currently have a machine for EBS R12 dual server configuration. One (1) server for applications and 1 for the DB.
  In my view, is a standard and the most common installation.
  Assuming that we have another 1 server just to improve performance, which component of EBS devrais I moved
  in the 3rd Server?
  
  
  Thank you very much

  It will be managed by balancing the load itself. As far as I KNOW, you have no control over this (i.e. you can tell the user which layer application for access to).

• More on RAM one 512 MB to 2 GB Windows XP Pro will improve performance?

  Hello & happy holidays to all!

  First of all, some info system for your reference.  (Computer was purchased USED (s) at the end of 2010).

  Desktop Dell Dimension 3000 (Internet modem cable connection)

  Windows XP Pro, SP3

  Intel Pentium 4 3.00 gHz CPU

  512 MB of RAM (256 MB x 2)

  40 GB HD (60% freespace)

  I noticed my computer becomes slow... cold boots / restarts, Internet connection, e-mail load, and even just to open Word or Excel, while offline.  A number of occasions, (using a stopwatch), I checked how long it takes to do just a restart.  From the moment where I press ENTER> key after entering my password, it took as long as 23 minutes for the system show 5 items in the to-do bar , etc., and the hard drive light to go out before I can even begin to do anything on the computer.  (All the desktop icons willl display within 10 seconds of a restart).  AV & anti-malware scans reveal no problem.

  My question is the following: upgrading the RAM from 512 MB to 2 GB [1 GB x 2] (acceptable according to the specifications of Dell), would provide a significant improvement in my computer speed & efficiency, or would I just lose money & end up to have to go and try to find a used computer with more memory?  Living on a fixed, disability leaves me with many options.

  Thank you for your time and suggestions!

  Considerably improve the performance? N °

  All you need to do is determine what process is hogging memory and/or resources. To do this, open the Task Manager and make sure that the process tab is selected. Click on the CPU. Then click again on the CPU. This will cause the greediest process in resources to display at the top of the list. You can do the same thing with use of Mem. In your next post, tell us what are the worst offenders of both.
  About the memory, here's a way effective to determine if there is enough (in other words, if your system is too much relying on the swap file):

  Open (Ctrl + Alt + Delete) Task Manager, and then click the performance tab. Then the three values under Commit Charge (k) Note: in the lower left corner: Total, limit and peak.

  The Total number represents the amount of memory you are using right now. The vertex figure represents the maximum amount of memory you made since the last boot. If these figures are lower than the value of the amount of physical memory (K), then you probably have lots of RAM. In case you want to study it more, you can run the Page queue Monitor for Windows XP:

• will I get the improved performance on windows xp using the pagefile in enhanced USB flash

  Lenovo 3000 J200 512 MB RAM slow operation with the new installation of windows.

  How do I do this

  Are you talking about something like ReadyBoost?

  http://en.Wikipedia.org/wiki/ReadyBoost

  That feature (and SuperFetch) are not available in XP.

  My opinion is that unless you know more about managing memory than XP, you must set the option for the paging file to the size of the managed system and just let XP take care of things.

  I read somewhere that there are none or only a performance problem minute if you can get the page file to XP on a USB key.  Keep in mind that flash drives will also be "usury" after a number of cycles of read/write so who knows how long to set up your continue to operate reliably if you were beat your USB device, day and night.

  If your system is slow, you must define what slow means for you and provide more details on your system.

  If you think that it starts too slowly: for example, I would use some software tools to measure boot time to the millisecond so that you can see exactly how long it takes, make some adjustments and measure again to see if things improve.  It allows to eliminate the human element of subjectivity in the matter.

  For example, I know that it takes my system exactly 24.03.024 seconds to start, but I have zero startup items configured at boot time.  Maybe this isn't the right configuration to everyone, but I'm all about the search for better performance.

  If your Lenovo will have more RAM, I would consider that.  512 MB is not a lot and RAM is relatively expensive, these days, and who would probably be on the best thing you could do for your system.  I can run XP with 256 MB, very good (but a bit slow), but more RAM is usually better - seek 2-4 GB if you can rotate.

  If you want someone to watch you have, follow these steps:

  Provide information on your system, the better you can:

  What is your Version of XP and the Service Pack?

  Your system have IDE or SATA disks?

  Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

  Now make some clarifications:

  Click Start, run and enter in the box:

  Msinfo32

  Click OK, and when the system info summary appears, click on edit, select all (Ctrl-A), copy (Ctrl-C) and paste (Ctrl-V) the information back here.

  For information about video drivers, expand components, click view, click on edit, select all, copy and then paste the information here.

  I have a list of your startup items will also help.  Here's a way to do it:

  So tell us what are all your startup items and we will help you to look at to see if there are some that you may not need.

  Here's a way to provide a list of your startup items:

  Download and install CCleaner here:

  http://www.Piriform.com/CCleaner

  Launch CCleaner, click on tools, startup and at the bottom right of the screen, click on the button "Save to text file" to save the startup information in a text file (name it something like startup.txt, so you can find it).

  Save the information to your desktop (or somewhere you can find it) start, open the text file with a text editor, select all of the text copy (Ctrl-A) it
  (Ctrl-C) and paste (Ctrl + V) the contents of the startup list of back here for analysis.

  Uninstall CCleaner later if you don't like (most people seem to like for it of other features).

  Here's what my startup.txt file looks like:

  That's right - I have zero startup items.  Maybe this isn't the right configuration to everyone, but I'm all about the search for better performance.
