• Performance and memory problem

  Location:
  
  Have a mapping in Informatica (SDE), who joins about 15 tables from the OLTP database to create the staging table. This process joins the tables such as accounts, orders, and control elements. Great process that joins with very large tables. The process has been running in about 18 minutes, a change has been made.
  
  Change:
  
  Added three additional tables in the join (account tables and references) to pull 5 new fields. Two of these paintings are large enough with the third being small.
  
  
  Question:
  
  Now, the process that was running in about 18 minutes is more than 8 hours to run. If I take the SQL mapping code and run it in SQL Developer, it runs less than a minute.
  
  Possible cause:
  
  Don't know what the problem is that suddenly caused the process to change so dramatically. One thought is that the addition of three new tables in the join can be maxing some Informatica cache in temporary memory (storage). Looking at the workflow and I noticed that the size of the buffer of DTM has been set to 36 m. Not sure if this aspect will have to be increased, or if there is another parameter that we need change. Any insight and help would be greatly appreciated.
  
  Thank you...

  Better find an Informatica forum with expert tool specific.

• Big client - vCenter 5.5 response time of the customer Web U1c / questions of Performance and Navigation

  So we're all aware of the issues with vCenter 5.5U1 WebClient and how we are forced to use it to make use of all the features of the v10, vDS 5.5 vHardware (config switch changes the synchronization problems if an emergency change is done on c# client vDS) VSAN only available via the web client, flash, sluggish to questions do not respond the questions and the list goes with the presentation of the menus and hard to navigate, issues SSO (always after 5.5 upgrades)

  So @ VMware vCenter Architecture Team is going to make an effort to hear and give due to the much needed performance improvements and improvements to the user interface before adding more features and SSO type services which majority of clients don't use not and not force it's customers continue to loose faith its vCenter product?

  Looking for answers with options to remove vCenter 5.5 U1c installation as well as a promise to answer to these in vCenter 6.0 version!

  Here is your answer. First of all, to use Chrome as your browser, then you need to go with at least 4vCPU * 32 GB of RAM & adjust the segment size of java for SSO, Tomcat, (TC) Management Server, inventory server and profile based storage to "refine" vCenter device with DB Oracle embedded or external memory. I did, and performance gains went 10 X. This includes the vSAN enabled running clusters. My recommendation that works very well based on design documents:

  vCenter Server inventory	VMware VirtualCenter Management Webservices (tc Server)	The inventory service	(Sps) profile-based storage service
  Large (more than 400 guests or 4000 VMS) stock	4 GB	12 GB	4 GB

  Setting on the vCenter server 5.5 of the memory unit

  • Connect the unit to vCenter server using SSH
  • VI /usr/lib/vmware-vsphere-client/server/wrapper/conf/wrapper.conf configuration file, locate the JVM memory section and change maxmemory to 4096

  Line 66

  # Memory #wrapper.java.initmemory = 512wrapper.java.maxmemory = 4096 JVM

  • /usr/lib/vmware-vpx/inventoryservice/wrapper/conf/wrapper.conf VI configuration file, find the setting. MaxMemory and replace it with 12288

  Line 116

  # Size (in MB) maximum Java heap wrapper.java.maxmemory = 12288

  • VI /usr/lib/vmware-vpx/sps/wrapper/conf/wrapper.conf find the setting. MaxMemory and change from 1024 to 4096

  On line 154

  # Size (in MB) maximum Java heap wrapper.java.maxmemory = 4096

  • Restart the vCenter device w / DB (1000 hosts) external /embedded for lab (100 guests)

• Window Media Player.exe using 100% of CPU and memory

  I have a Pavilion dv4-2145-dx Windows 7 Ultimate SP1, 4 GB of memory. Windows Media Player.exe supports my CPU 100% usage and it is striking all my memory - 4 GB.   It started right after I set up a homegroup.

  I had to go into Admin/service and change the Startup Type to disabled for:

  • Windows Media Center Receiver Service
  • The window media services planning service
  • Windows Media Player Network Sharing Service

  I tried setting services to manual, but Windows Media Player has yet caught all the CPU and memory, he could then I disabled all the.

  I do not know how to disable homegroup and Windows Media Player services work together so I wonder if everything is always operate has designed with the homegroup and sharing my music.

  Hello

  I think this explains the problem.  The 2 entries here should be deleted, because the first will try to index all of your user profile and the second will attempt to index all of the Windows Partition.

  To remove them, click to the left of the entrance, highlight it, and then click Remove.  When these two entries have been removed, reboot the laptop and you should find that the problem has been resolved.

  I plan to upgrade my OS to El Capitan.  What are the processor speed and memory required for the operating system works well?

  I use a processor 2.3 GHz Intel Core i5 with DDR3 4 GB 1333 MHz memory.

  My last similar attempt on another machine resulted in a very slow computer.

  Thanks, Ron

  Apple says the following:

  General requirements

  • OS X 10.6.8 or later version
  • 2 GB memory
  • 8.8 GB of available storage

  For best performance, I would say not less 4 GB and preferably 8 GB or more.

  Your i5 is well able to support properly.

  I have a P100-160 with 2 GB of memory installed.
  I use Win7 (32 bit) and do some really serious graphics, and management changes.
  I use about 2.75 TB of hard drives (USB).

  Can you get it someone please let me know if I could reasonably expect to see an improvement in the performance and reliability by increasing the installed memory.

  Other (other than buying a new laptop) suggestions for performance improvement would be welcome.

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)

• Monitor performance and reliability of Vista not updated

  Hi all

  I have a HP Pavilion dv4 Vista SP2 machine is installed. From time to time, I check the performance and reliability of my machine monitor. Recently I discovered that reliability monitor has not been updated since 17/03/2012, while performance monitor is OK. I've used various methods to overcome this problem to delete the contents of the folders PublishedData and stateData evolution of their access permissions. However, no method has been of assistance. I also tested my memory with the Memory Diagnostic tool, and if all goes well no error has been detected.
  When I check the Task Scheduler RacAgent.exe, everything is OK and its State is mentioned as queued. But when I run it, nothing happens and the last Run result shows 0 x 0. Also when I run the command line RacAgent.exe nothing happens. I should mention that a few days ago the RacAgent.exe worked normally and the task manager has also shown its process for about 30 seconds and the field last result run the task scheduler has shown other useful addresses, but even at that time there, I had the same problem: reliability monitor not updated.
  I really need your help and I look forward to your itinerary
  Best regards

  Hey Amir,

  Thanks for asking! Looks like there could be possibly a corruption of system files or an infection. We will check by running the associated scans.

  The auditor of file system (CFS) scanner to check any file system corruption. Follow the article here.

  In addition, run Microsoft Safety Scanner to check any infections. Read this article for the same thing.

  I hope this helps! Don't answer that if they do not help, we can seek other options.

• Merging databases and memory settings

  I have two separate long-term database server (11r2 on RHEL 5). We seek to combine them into a single server in order to reduce the costs and delays of the admin. On both servers, I can run...

  select * from v$sga_target_advice order by sga_size;
  

  .. .and get plenty of data on each box. I can check the current sizes for parameters static EAMA does not dynamically as well.

  Question: if I'm their fusion, the initial memory parameters (sga_target, etc.) must simply be the sizes from two servers added?

  Aka, if SGA_TARGET is 4 GB on db1 and 5 GB on db2, the combined server is 9 GB?

  Thank you

  You should study hugepages.

  Sybrand is correct.  In a dynamic system with many variables, the merger of the two systems is not additive.  You go through an iterative process of adjustment.  Even the advisers are only a starting point, they tend to want to, just to keep memory more.  Find the paper to think clearly on Cary Millsap's performance and consider there are probably things that are fine when separate them, but you cut above the knees when combined.  Unless, of course, the two systems are currently passing too provisioned.

  You should be able to anticipate some things by taking the CWA (if authorized, statspack if not) reports to see what is normal.  Keep just a few looks at the pga and sga statistics.  Redo the calibration is probably something that is additive.

• Toshiba A50-frequency of 106:FSB Bus and memory problem

  Hello
  I have a problem with my new Toshiba A50-106. There are Celeron M 1, 5 GHz inside. That all specifications for this processor FSB speed should be 4x100MHz and for my memory bus speed should be 2 x 133, but when I check in SiSoft Sandra 2004 I see 4x187MHz (748 MHz) FSB and the speed of the Bus of Mem 2x249MHz (4 98 MHz). I can't fix it myself, because there is no such option in the BIOS and there is no standard software from Toshiba.
  Consequence of this is the problem of the temperature of my cpu. It is on average 54 c in an idle state.
  Perhaps you have had the same problem or knows what is in him and you can help me.
  What is a temperature average of your Celeron M?

  Thank you in advance,
  Michael

  Hi michael,.

  to your first question, have you run Sandra 2004 in battery mode because in battery mode CPU manages to set the speed of the FSB and memory also bus speed!

  So, try once more on AC power mode and let me know the results.

  Also, you should check these results with different bechmarking systems because these programs work differently.

  @ temperature problem: there is problem o with 54 HP. The home page of intel, said a 125 C is the maximum and then the CPU stops automatically!

  Hello:

  Your model does not include built in bluetooth network.

  The Atheros wireless network adapter is only wireless, not an adapter without wireless/bluetooth combination.

  You need this driver for the SD card reader...

  This package contains the driver that allows the Realtek card reader in laptop models running a supported operating system. The card reader allows users to read or write to removable storage cards supported, which are typically used in digital cameras, digital music players and cell phones.

• Daily series VS Performance and entertainment?

  HP has desktop computers in the "Everyday Computing" and "Performance and Enterment" series.

  I adapted a desktop computer in both series.  For the series of performance and Entertainment Office, you get more choice of components.

  However, the components that I need are available for both series.

  In addition, desktop computers has the same motherboard.

  If desktop computers have been adapted with the same components, wouldn't they have the same performance?

  I understand what you ask because I did the same thing and had the same questions.  The answer is Yes.

  But there are other differences between the two lines, in addition to the customizable options of cpu, ram, disk hard size and chip/card graphic.  Click the tab of the sheet and you'll see different chassis sizes, sizes of power, a different number of slots, etc.

  The series 'Performance and play' has a more robust architecture and is easier to add updates in the future, as the media platforms continue to evolve.  Also gives you a little more space inside to work with.

  I hope this helps.
