Memory Tuning - SAPPFPAR check

I was wondering on how to optimize the use of "SAPPFPAR check" in terms of Memory Tuning. Upon typing the command "sappfpar check pf=<profile>", the shared memory disposition overview is being shown. Are the values shown here present the current values defined in the system?
Furthermore, i was wondering what values are shown below? Do all the values shown below display the currently allocated values in the system or are the values shown below display the required value at the very least? If so, how can i change the value? How do i know what parameter these values are directly corresponding to so that i can check and change the said values if necessary? Especially the values shown in the "worst case" field, how can i check whether the currently allocated values satisfy what are indicated in the SAPPFPAR check?
In addition, i was wondering what does the error imply? Does it straightforwardly imply that there are incorrect values existing in the system, or does it imply that requirements are not met, or etc. I would like to know more about this from the SAP practitioners themselves since experience provide the best knowledge that can be taught since it occurred first hand.
Kindly enlighten me on this topic. Thanks.

Hi
The SAPPFPAR checks the current values that is mentioned in the instance profile . Unless if u have made changes to the instance profile. If u do make changes to the profile then the SAPPFPAR will show the result for the changed profile.
The output given by the SAPPFPAR will show you the current value and the required value (ie Proposed SAP values) to be changed. If there is any error in the profile parameters it indicates that in the output. Eventually it calculates all the SAP buffers , Physical memory and the SWAP space. It gives you the total required memory by adding the worst case scenario (heap) alongwith the buffer parameters.
When u change the buffer parameters for the system, it will calculate and adjust according to the SAP proposed value. Since the shared memory values depends on all the buffer parameters like program, screen, table buffers..etc.
The SAPPFPAR is a very helpful tool for calculating the physical memory space required based on the SAP buffer and for checking error in the instance parameter.
Thanks & Regards,

Memory tuning

Any memory tuning to improve window 7 enterprise performance? Pls advice

Hey Sam,
There are some things that can improve performance, because I wrote things that moderators do not have the specs of the computer and the software installed.
Cooling is important to have a good enough computer, and check the temperature of the processor (Fans often recommended to replace it incredibly improves performance)
Check out time access I / O hard disk (using Disk HIRENS possible) and check the disk responds correctly (50-100) and no BAD SECTOR.
Consider replacing the hard disk type SSD (much faster).
Some of the installations intelligently (often prefer a clean OS install on a single drive, and a different drive programs to improve performance).
The file FILE PAGE Put on your operating system is different.
The PAGE file FILE Put a different operating system drive and limit it according to Microsoft's recommendations (usually between 1.5-3 size of RAM).
RAM memory is recommended at least 8 GB, and check that the operating system supports (64 bit)
Remove the effects that operating system kit (fade effect & aero theme)
Please Mark This As Answer if it helps to solve the issue

High memory use when checking downloads folder through browser

High memory use when checking downloads folder through browser.
I have a total of 3 DDR2 Gbytes of ram. Pentium(R) Dual-Core CPU T4500 @ 2.30GHz Win 7 home pr. 64bit. Firefox 27.0 beta
I right click on a file to "open containing folder" from the drop down menu in downloads.
When the folder has been opened, explorer is trying to index the folder (which it never does completely or well after 5 minutes I close the folder and shut down the dllhost process cause laptop is blazing hot) and memory keeps increasing till no more is available.
I checked task manager and see that dllhost is the particular process that is causing the spike in memory usage even after closing the folder I right click and stop the process and memory is restored after awhile.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.

''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''

Windows 2003 Memory Dump - Bug check Analysis attached

Hi all
I recently have had a Windows 2003 Standard with SP2 server crash with a memory dump
I have used WinDBG to read the file and output below
can anyone shed any light on the faults, or point me in the right direction?
*                        Bugcheck Analysis
KERNEL_MODE_EXCEPTION_NOT_HANDLED (8e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:

Where is the option to not load duplicates. Every time I load a memory card bridge checks off ALL photos and wants to download previously downloaded photos.

How do I get Bridge to not load duplicates automatically. Now I have to check off new photos when I load a memory card. I can't find the setting to do this.

HP Unix memory tuning

Hi.
i want to increase PXA buffer size in ECC 5.0 -Netweaver 2004
OS -HP Unix
Ram:16GB,Number of swaps per day very high.
Existing size:220MB .Will it result in any OS related problems
Is PXA Parameter dependant on any oher sap paramters?
Regards
Arun

Dear Arun,
Some recomendations for this buffer area are given in note 103747.
I recommend to you after increasing the size, run sappfpar command on operating system level
in order to detect any memory errors or warnings.
If number of swaps are high, it could be a good idea to increase it, or to move to a faster drives.
Hope it helps.

Need help with performance & memory tuning in a data warehousing environment

Dear All,
Good Day.
We had successfully migrated from a 4 node half-rack V2 Exadata to a 2 node quarter rack X4-2 Exadata. However, we are facing some issues with performance only for few loads while others have in fact shown good improvement.
1. The total memory on the OS is 250GB for each node (two compute nodes for a quarter rack).
2. Would be grateful if someone could help me with the best equation to calculate the SGA and PGA ( and also in allocation of shared_pool, large_pool etc) or whether Automatic Memory Management is advisable?
3. We had run exachk report which suggested us to configure huge pages.
4. When we tried to increase the SGA to more than 30GB the system doesn't allow us to do so. We had however set the PGA to 85GB.
5. Also, we had observed that some of the queries involving joins and indexes are taking longer time.
Any advise would be greatly appreciated.
Warm Regards,
Vikram.

Hi Vikram,
There is no formula about SGA and PGA, but the best practices for OLTP environments is for a give ammount of memory (which cannot be up to 80% of total RAM from server) you should make 80% to SGA and 20% to PGA. For Data Warehouse envs, the values are like 60% SGA and 40% PGA or it can be up to 50%-50%. Also, some docs disencourage you to keep the database in Automatic Memory Management when you are using a big SGA (> 10G).
As you are using a RAC environment, you should configure Huge Pages. And if the systems are not allowing you to increase memory, just take a look at the semaphore parameters, probably they are set lower values. And for the poor performance queries, we need to see explain plans, table structure and you would also analyze if smart scan is playing the game.
Regards.

Windows XP 32-bit Virtual Memory Tuning.

For our PXI racks we "tune" the virtual memory under Windows XP 32-bit (standard NI installation), as a couple of our applications process vast volumes of data , as follows:
Open boot.ini
Find the line beginning with 'multi'
Add the following to the end of the line '/3GB /userva=2560' (without the quotes).
Initially we were supplied with PXIe-8133 driven PXI racks and the above change works perfectly.
However later PXI racks were supplied with PXIe-8115 driven PXI racks. If the above line is applied to these PXI racks then the result is the graphics card drops to 640x480 4-bit colours and it cannot be changed until the line is removed.
I have tried various values for /userva including 2176, 2432, and 2304 but all results in the same result.
It seems that whilst the PXIe-8133 came with a standard BIOS and hence was configurable to an extent, the PXIe-8115 comes with a NI BIOS and provides very little low level control in comparison.
Has anyone attempted the above on a PXIe-8115 driven rack? Or can suggest a solution?
Thanks.
Christopher Povey
Senior Test Systems Engineer for BAE Systems.

I have attached the Windows XP System Resource Maps for both our PXIe-8115 and PXIe-8133 racks. Both racks contain the same hardware in the same slots (apart from the controller card).

Memory tuning imap store

Hello,
i m trying to tune my web application, a web mail, once a user logs in I keep an IMAPStore instance inside the httpsession.
I noticed it takes 6 mb of memory right away, just after connecting to the imap store, once I open a few folder and fetch a few small messages it goes up to 8 or 9 mb.
to get messages i follow this steps:
- openFolder
- fetchmessages
- populate my beans
- invalidateheaders for each imapmessage to release cached data
- call folder.clearCache() (i added this method inside imapfolder to clear messageCache vector)
- close folder
but memory usage is still the same.
Is there anything to reduce memory usage? i should have no more than 1MB per session.
Thank you.

Hi,
I am using MessAdmin to measure HttpSession data.
6mb is the size of IMAPStore, and this size appear even if i don't open a folder, just after getting the store:
session = Session.getInstance(props, auth);
session.setDebug(debug);
store = (IMAPStore) session.getStore(imap);
store.connect();session and store object measure 6mb.
If you have a better tool please let me know.
thank you

Im here regarding my memory usage. i checked my memory and calculated it but it doesn't show as the amount i calculated. it gives me more 7GB. i dont understand where did it go. Can someone please explain to me?

what i mean is my ipad shows used memory is 16gb but after i added up myself it is not that value. i calculated 10gb. who can help me to explain where did i use my another 6 gb.

Connect the iPad to your computer and look at the storage used by the various categories as shown in the colored bargarph in iTunes.
How does that agree with what is shown on the iPad? How large is the "other"?

HADB Memory tuning?

Hi all,
We have installed ONLY HADB component from SJSAS 9.1. As we are using Java 1.5 version, the default jvm heap size is 192m which is way less than our requirement. How can I tune the JVM used by HADB? I saw that the service clu_nsup_srv running under JVM process.

SD memory is always checked at startup

I recently bought a Treo 700wx. If I leave the phone powered off for a few hours then go back to it, once i turn it on, I get a message that tells me a "storage card was inserted. Do you want to search it for audio and video files?"
How can I stop this nuiciance from occurring?
Thanks!
Post relates to: Treo 700wx (Verizon)

Do you have an SD card in the Treo?
Try a 10 second soft reset by taking out the battery for at least 10 seconds. This allows the device to power off completely, like a shutdown on a PC.
For reference purposes, click on the following link for the support page for your device on the kb.palm.com webpage.

and correct the values mentioned in the instance profile as suggested in the error list.
or you need to increase the Shared pool size in the DB profile.
