Proccesses goes to PRIV mode
Hi, we have problem with proccesses going to PRIV mode (SAPHTTP), extended memory:
Roll, extended and heap memory EXTM
ztta/roll_area 3000000 Byte Roll area per workprocess (total)
ztta/roll_first 1 Byte First amount of roll area used in a dialog WP
ztta/short_area 1600000 Byte Short area per workprocess
rdisp/ROLL_SHM 16384 8 kB Part of roll file in shared memory
rdisp/PG_SHM 8192 8 kB Part of paging file in shared memory
rdisp/PG_LOCAL 150 8 kB Paging buffer per workprocess
em/initial_size_MB 4092 MB Initial size of extended memory
em/blocksize_KB 4096 kB Size of one extended memory block
em/address_space_MB 4092 MB Address space reserved for ext. mem. (NT only)
ztta/roll_extension 2000000000 Byte Max. extended mem. per session (external mode)
abap/heap_area_dia 2000000000 Byte Max. heap memory for dialog workprocesses

abap/use_paging 0 Paging for flat tables used (1) or not (0)
have You any advice?
Thanks
Hi,
A process going into PRIV means that either it has exhausted its quota of extended memory (ztta/roll_extension) or that the total extended memory (em/initial_size_MB) has been used up by other sessions.
The parameters look pretty standard, but you must determine the memory usage at the time you see a PRIV process. Do this via SM04 -> Goto -> Memory.
Another piece of advice: when you ask a question about memory-related issues, please always mention your operating system (Windows, UNIX, Linux, ...), O/S release and SAP release. SAP memory management has quite a few platform dependencies in it.
Regards,
Mark

Hi Gurus,
WP's are going to priv mode. user is not accepting to kill the process or reduce the number of records. what is the best way to do as a basis consultant?
Thanks in advance.Dear Sahad,
<PRIV> mode will be used if the work process starts to allocate heap - or private,
thus PRIV - memory. This is not necessarily a bad thing. There are two scenarios
that may lead to such a system state:
1. There is a small number of users that create huge contexts. In this case, it
will be OK to have such users allocate memory from heap and exclusively lock
a work process for them (this is a side-effect of the PRIV state, as heap memory
content can not be seen by another process, and the user context can no longer
be 'rolled' into another work process. The limit when this will happen is either given
by the ressource limit (em/initial_size_MB, EM/TOTAL_SIZE_MB) which is the
overall amount of extended memory (EM). EM is a shared memory. The other limit
is a user specific quota given by ztta/roll_extension (or ES/SHM_MAX_PRIV_SEGS
for AIX, when ES/TABLE=SHM_SEGS is used). As I said, this is normally OK, and
a small number of PRIV processes is not a problem at all.
2. The user contexts are equally big, but there is not enough EM available on the
instance. This will force EVERY user context into PRIV, as soon as the EM is
exhausted. The fact that EM is exhausted will be seen in transaction ST02 (look
for SAP Memory, Extended memory). Also check with transaction SM04, Goto,
Memory, the size of the user contexts. In this case, increasing EM, or reducing the
amount of users on the instance are your choices.
As I said, if this is only one or two work processes, you must not worry about them.
Best Regards,

Dialogue workprocesses going in PRIV mode
Dear all,
More than 95% of dialogue work processes are going in PRIV mode
The extended memory in ST02 is 100% full
Nobody is able to do nothing
Below pasted are the values from the instance profile
ztta/roll_extension 4000000000
rdisp/wppriv_max_no 1
zcsa/db_max_buftab 10000
sap/bufdir_entries 6000
rsdb/obj/large_object_size 16384
rsdb/obj/max_objects 4000
rsdb/obj/buffersize 8192
rsdb/ntab/irbdsize 9000
rsdb/ntab/ftabsize 45000
rsdb/ntab/entrycount 30000
rsdb/cua/buffersize 6000
abap/buffersize 600000
zcsa/presentation_buffer_area 6600000
zcsa/table_buffer_area 30000000
ztta/parameter_area 8000
auth/auth_number_in_userbuffer 9000
Any suggestions?Dear all,
Problem was with the following two parameters: --
em/initial_size_MB = 512
em/max_size_MB = 512
De-activating these 2 parameters in instance profile, solved the problem
Thank you all
Would like to add some more here just in case if anyone wants some more details: --
If a Dialog work process has used its quota of Extended Memory (EM) defined by parameter ztta/roll_extension OR all EM has been used up by all the other work processes (em/initial_size_MB), then the task starts to allocate HEAP up to quota (per work process) of abap/heap_area_dia.(this is PRIV mode).
To investigate, check out the dev_w* trace file, to check which program cause work process go into PRIV
Also, follow what Markus has suggested
You can try to set rdisp/wppriv_max_no to prevent this kind problem.
Exmaple: If you set it as 5, will limit only 5 work processes go to PRIVmode.
Please also update your kernel patch to latest version, if you haven't done so.

Stop DIA work process with PRIV mode.
Hi,
How to stop DIA workprocess with PRIV mode. by searching notes, I find it is possible to setl the max time and max number of the private memory.
Kind regards,
MasaakiHello Masaaki,
Before deciding whether to wait for the process to finish by itself or not, i would suggest that you find out the program which is causing the work process to go into PRIV mode. Once this is done, as your technical guys (ABAP) to analyse why this is happening (is the program logic inefficient and hence using so much memory etc).
You have to note that (Dialog) work processes going into PRIV mode is not a healthy sign for the SAP application server.
This is beacuse once the WP goes into PRIV mode it is not available to any other transactions, and we only have a limited number of work processes.
Please make sure the parameters below are defined in RZ10 instance profile:
rdisp/max_priv_time - used to define the maximum time that a work process can remain in PRIV mode. (After this the work processes is terminated and restarted). This is reasonable because beyond the time limit set, it is imperative to assume that the program using the work process is in efficient. (in case a program really needs that much time, it needs to be scheduled as a background job).
rdisp/wppriv_max_no- this parameter defines the maximum number of work processes that can be in PRIV mode. Very useful.
Also, make sure that a parameter ABAP/heaplimit is defined. This ensures that if a program eats up a certain amount of heap memory, the work process being used can be terminated.
And finally please do check if your extended memory allocation is not big enough. the parameter em/initial_size_mb defines the fixed size of extended memory. Increasing this size only if you find that a lot of processes are frequently going into PRIV mode.
Hope this helps.

Hi all,
We are facing problem in SAP. The performance of the system is very low and all the dialog workprocess are entering 'PRIV' mode in 'ONHOLD' state.
Can you please say me what are the possible reasons for process to enter 'PRIV' mode?
Thanks in advance
Regards,
Sowmya KHi,
If all the work processes are going in the PRIV mode, it is very possible to be Kernel bug which you can check with SAP.
Understanding the HEAP memory better, If a dialog work process has used up the roll area assigned to it and the extended memory, private memory is assigned to the work process. The work process goes into PRIV mode (private).
In the parameter settings, ensure that not too many dialog work processes are simultaneously in the PRIV mode, since this lowers system performance.
The other Work Process types (background, update, enqueue and spool work processes) are assigned heap memory after the roll area is used up. Allocating Extended Memory is not useful since no context change occurs for these processes.
Other processes cannot use private (heap) memory. After releasing the assigned memory, the operating system still considers the (virtual) memory as being occupied by the allocating process. These characteristics of heap memory require that:
1. The work process can be run in PRIV mode (private) when the local memory is assigned. This means that the work process is reserved for processing the current user context until the context releases the work process again when the request has ended.
2. The work process, if it has used a lot of private memory, is restarted when the user context is terminated and the local memory is returned. The restart makes the local memory available again for other processes. A restart occurs if a work process uses more local memory than is defined in the parameter abap/heaplimit. The mechanism is displayed again there.
Automatic Termination of PRIV Mode Processes:
If too many dialog work processes run in the PRIV mode in an SAP application server, performance problems arise. The normal processing of user inquiries is slowed down by the PRIV mode work processes.
The SAP System offers a mechanism that lets you terminate non-active dialog processes in the PRIV mode. This mechanism helps reduce performance problems.
The mechanism works as follows:
In the PRIV mode, a maximum number (n) of dialog work processes can run without any time restrictions.
To determine this number n, set the value of the profile parameter rdisp/wppriv_max_no. If a value is not entered, the SAP System determines this number using the following formula:
the number (n) is set to the greater of the 2 following values:
Number of dialog work processes minus 5
1
If more than (n) dialog work processes are active and the time span set in parameter rdisp/max_priv_time (default 600 seconds) has elapsed, the transaction for that PRIV process, which has spent the longest possible time in PRIV mode, is reset.
Hope this information helps in sorting out the issue.
Thanks

Hi Experts,
We always found there are users using more than 2GB for transaction, so we did the below changes in our system to avoid fragmentation and paging of extended memory
1.Instead of allowing a process to grab 2 GB of (shared) extended memory before going in PRIV mode, the limit will be reduced to 800 MB.As a counterpart, private heap memory limits will be increased from 2 GB to 3,2 GB.
2.So total maximum memory per user is still 4 GB, but high memory users will have to "pay for it"
3. The advantage is that private memory is given back to the operating system once the transaction is finished, whereas shared extended memory is never given back (by design).
our assumption is we would never see MaxUse of extended memory > 12 GB in future.so users are allowed getting PRIV mode from time to time in our production.
But now we are getting some other problem.We are getting too much OS paging (according SE06)
Just what to confirm here with the experts
1. This PRIV mode of the WP uses the needed memory exclusively, the WP will not be interrupted and so uses much CPU, so Priv mode causes the high OS paging.?
2. Does SE06 includes the OS paging with IO?
3. What are the other options we do have to reduce this high paging
Please guide
Thanks,
Jansi1. This PRIV mode of the WP uses the needed memory exclusively, the WP will not be interrupted and so uses much CPU, so Priv mode causes the high OS paging.?
PRIV mode or not, paging will occur if there is not enough memory. Even in PRIV mode, WP will be interrupted at O/S level if O/S follows round-robin method(UNIX) of assigning tasks to CPU.
2. Does SE06 includes the OS paging with IO? I assume yes.
3. What are the other options we do have to reduce this high paging
Here are options:
1) Tune ABAP programs.
2) Add more memory. How much (AVG)free/min/max memory you see every hour in st06? If you see really low memory almost every hour every day, then I would either try to add more memory or tune ABAP programs or review memory allocation to different components(DB/SAP system(s)/Any other application/Java if dual stack) more carefully and revise allocation if needed or perform all of the above.

Mac Tower Pro 10.8.5 keeps going into sleep mode
Purchased from Apple, refurbished 2012 Mac Tower Pro. At the same time, purchased a new Dell U2713HM, 27" monitor.
Have been operating on this new system since about the first week of December 2013.
Issue:
The computer has constantly gone into sleep mode after a few minutes of no activity. I can have iTunes radio playing, but the system still goes into sleep mode. As I am typing and moving the curser, the machine stays awake.
This has caused much frustration because when it goes into auto sleep mode, it quits all programs that I am in, and when it does this, I lose all the work I had accomplished. It litterally closes everything and goes to sleep in about 2-3 minutes of no activity.
BTW: the computer and monitor have all its new OEM cables that came in the box, when I purchased the units.
Solutions attempted:
System Preferences — Energy Saver: computer sleep and display sleep set to "never" and unclicked the box "Put hard disks to sleep when possible."
Dell settings: Turned off all energy savers.
Results:
Nothing. Problem persists.I apologize for the angst. The problem has cost too much money in lost time and material because when it would automatically shut down after a few minutes, all my work was lost.
I misunderstood the terms of the warranty. Thank you for your input and patience. Much appreciated. For the benefit of others that experience this with a new Mac that auto shuts down. Check the following:
1. Go to System Preferences.
2. Click on Security and Privacy.
3. Click on Advanced (bottom right corner)
4. If the first line is checked (Log out after 5 minutes of inactivity); uncheck it and then click OK button.
5. Be sure to click the lock before existing Security and Privacy.
Now the machine will cease shutting down programs to go into sleep mode as soon as machine is inactive for a few minutes. -
My macbook is two and half year old, going to sleep mode randomly
Having used this Macbook for almost two and half years, my machine has suddenly generated the problem of going to random sleep. It started as an infrequent thing, then it started happening on a regular basis, to the point that it became almost impossible to work with it. When the computer goes to sleep mode, it doesn't wake up with any key, it has to be woken up by pressing the power button lightly.
Here are the steps I took:
1. The normal thing I did was search Apple Forum and then reset SMC, PRam, then changed energy saving options, everything. Nothing worked.
2. Ran the hardware test and no problems found.
3. Ran the Macbook with all options: with just the battery, without the Magsafe connected, with Battery and Magsafe connected together, with battery removed and the computer running on Magsafe only. Random Sleep continues
4. Thought must be a connection issue and ran to Apple Store in Kolkata, India, thinking that it could be a connection issue with the sleep-mode cable. Apple Store kept the Macbook for seven days, saying that they needed to check the machine, returned it on the seventh day saying that the machine was fine and charged me Indian Rupee 1,500/- (about $ 34). I came back home and the problem persists.
(Here I would like to add that Apple Service in Kolkata *****, probably ***** all over India, simply because Apple is not a major player in this country. The service engineer at Apple Store was at a loss with my problem and after seven days could only say, "We have done our internal tests and found no problem with your Macbook." When I asked about the Sleep Mode sensor connection, he said, "That is working fine, we have checked that.")
5. After coming back home, I faced the same problem, this time with lesser time gap. It would go off to sleep every one minute or so. I decided to set my computer on "never to sleep mode" in the enery saving option. Alas, that didn't help either.
6. I redid the hardware check, only to find that my computer hasn't detected any hardware problem.
7. Now, as a previous Windows user, I thought that the problem must have been with the OS. So, at the risk of losing all my files, I decided to reload the OS. (My original OS DVD was Leopard, but it was later upgraded to Snow Leopard by the vendor free of cost). I took backup in Time Machine, and backed up the documents in another Disk and reloaded the OS. All seemed fine so far, for about 10 minutes. I was now confident that finally I could solve the problem and was then planning to migrate my previous files to my newly loaded OS-X. Alas, I was wrong. Before I could connect the external HDD to my computer, my Macbook went back to its previous trick of falling asleep.
I'll definitely take back my Macbook to Apple Care tomorrow, but with my experience here in Kolkata, don't know whether they would be able to solve anything. Last time I had to show them the posts in Apple Forum to prove that Random Sleep is a problem that happens to Macbook.
PS: My Macbook is with aluminium body bought in January 2009. Out of warranty. My optical drive conked off long ago (after about 15 months or so after I bought the Macbook) and I live with an external drive.Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -

If you have followed the standard Apple troubleshooting processes (see user guide )
probably a trip to the local Apple Store Genius bar is called for before warranty runs out
Assuming the iPad has been released in your Country if not you may have to take it to a

Early 2008 iMac (8,1) randomly goes into sleep mode
Hey,
My early 2008 iMac (8,1) on 10.8.2 goes into sleep mode by itself. I've played around in Energy Saver, tried resetting SMC, NVRAM, replaced HDD, reformatted HDD, installed smcFanControl, reinstalled Snow Leopard, Lion, Mountain Lion. None of that worked. Took it to the Genius bar, performed some diagnostics tests and they said everything worked properly. Does anybody have the same problem? I can still use the computer for general computer use (light web surfing and e-mailing), but it seems to go into sleep mode when I have a lot of applications open and especially when watching videos. I've tried researching this problem, but I've haven't found a definitive answer. Right now, the Genius that I've been talking to thinks it may be the RAM. I'm waiting on new shipments of test RAM to arrive at the Apple Store for him to properly diagnose.
Thanks,
Jason
iMac (8,1)
2.8 GHz Intel Core 2 Duo
2x2 GB 800 MHz DDR2 SDRAM
ATI Radeon HD 2600 Pro 256 MB
1TB 7200 RPM SATA ST1000DM003-1CH162
If you want to read the whole time line, I've included it here. I apologize for it being so long.
At first I was running Lion (10.7.5) and the computer would enter sleep mode whenever I was doing anything with video. For example, watching YouTube videos and chatting on FaceTime. And funny enough, I distinctly remember watching a bunch of movies with VLC and the computer did not go to sleep (Although, this is not true anymore). I could wake the computer up and use it, however within a few minutes the computer would re-enter sleep mode. The computer seemed fine and I could access all of my files. Tried resetting SMC and it did not resolve the issue.
I made a Genius appointment to see if they were familiar with the issue. The iMac passed the in-store diagnostics test; it said all the components were functioning properly. He told me to bring it home to do a fresh re-install of my OS and then run my computer to see if the problem persisted. I took it home and reformatted my HDD with a 35-pass erase, re-installed Snow Leopard (10.6.8) and declined to transfer any backups from Time Machine. I was using a fresh system and sure enough, the problem persited. Tried doing the same thing again but with Lion (10.7.5) and still no luck. So I made another appointment and it passed the in-store diagnostics test again. I let them keep the computer for a 24-hour diagnostics test. They told me they would diagnose my computer with the OS on my HDD as well as a copy of OS that the Apple store deemed 'good' on an external HDD. The Genius called me and told me that my HDD failed their 24-hour diagnostics test and recommended I replace it. I initially had a 750 GB HDD, and the Apple Store could only offer me a 500 GB HDD ($200). I opted to take my computer to Carbon Computing, an authorized dealer in Toronto, to have a 1 TB Seagate HDD ($170) installed with no OS on it. I brought it home, performed another 35-pass erase and installed Snow Leopard. Problem still persisted. Repeated with Lion, still unsuccessful. Looking back, I was so excited that I just had to replace the HDD to fix the problem, I forgot to ask the guy if he could recreate the issue.
I began to suspect that it was a heating issue. So I installed Temperature Monitor and smcFanControl, and cleaned the fans as much as I could without taking the computer apart. Without smcFC on I tried to recreate the problem and I noticed that the Power Supply Position 1 reached 95 degrees Celsius, and Graphics Processor Temperature Diode reached 97 degrees Celsius before entering sleep mode. I don't know much about temperature sensors and what they monitor specifically, and so I couldn't draw any conclusions from that data. I turned on smcFC and cranked the optical drive speed to 2000 RPM, HDD to 3000, and CPU to 3000. The computer still went to sleep but the temperatures were below 90 degrees Celsius before entering sleep mode. I've tried researching here and on the internet about normal operating temperature ranges of iMacs and generally found that most do reached that temperature but they do not go to sleep mode.
Then I thought it may be a problem with Lion so I upgraded to Mountain Lion. The issue still persisted. Tried resetting SMC and NVRAM, did not resolve issue.
I called the same Apple Store explaining to them that their recommendation of replacing the HDD did not resolve the issue. They told me to bring it in and have them check it out again. I went through the same process I did before; the iMac passed all of their diagnostic tests. The Genius told me this time he will test out the RAM. He called me and told me that he could replicate the problem and so he proceeded to put in a stick of 'good' Apple RAM, but the computer would not work. He said the 'good' Apple RAM was damaged, either before or in the process of putting it in. He plugged in my old stick of RAM and the computer worked. He tried to recreate the problem and claimed that the computer ran for over 24 hours with an existing movie on my HDD playing and it did not go to sleep mode. However, once I brought it home I played the same movie right away and it turned off 17 minutes into the movie. Tried resetting SMC and NVRAM again, ran the movie again, still went to sleep.
And that's the story for now...Now to find out WHY it does it at home only. How hot is it at home? Have you checked the AC current/voltage at home?
Well they were able to replicate the issue at the Apple Store the second time I left my computer there. Anyway, we don't have any heating on at my house at the moment. It's usually from around 20-23 degrees Celsius (72-75 F). Temperature Monitor says ambient temperature is 30 degree C though...
I'm not really sure how to check the AC current/voltage at home, but my computer worked before I moved it. So I'm not sure if that is the issue.
I normally only have speakers set up to my computer and a wired keyboard. The speakers are powered separately. I would assume that at the Apple Store only the power cord and wired keyboard are connected.
What is the Power Supply Position? And what does it do?
Thanks for your help! -
HP Officejet 4620 All-in-One Loses Connection to Wireless Network When It Goes Into Sleep Mode
My HP 4620 All-In-One wireless printer works fine until it goes into sleep mode. Once it goes into sleep mode, it doesn't wake up if a print job is sent to it. If I wake it up manually by pressing the blinking on/off button, it still doesn't print. If I completely turn it off and then on again, the print job that was queued on my computer will start printing, but that's a huge pain and waste of time nearly every time I want to print. I've installed all available updates. I also assigned a static IP address in an effort to correct this but nothing helps. I see that others have complained about this problem, but I do not see that anyone has had success resolving this. My operating system is Windows Vista. I use a Link-Sys Wireless G Router. Thanks.
This question was solved.
View Solution.so I have called HP tech support 12 times over the last 6 weeks and still my HP Officejet 4620 loses connection overnight. Of course becasue it was a birthday present I spent more time than I normally would have on this issue. While the tech are very polite they have not fixed my problem and now it is too late to return printer to store. This is a lot of money wasted and I think they need to admit this is a bug in this printer and resolve the problem!!!!!

How can I select shutdown & close the display w/o going into sleep mode?
I have learned to wait untill the MBP full shuts down before closing the display. In the past I have pressed shutdown closed the display only to find out later the MBP goes into sleep mode before fully shuting down. When I reopen the display the computer finishes the shutdown process or worse the battery is dead.
I would like to select shut down, close the display and walk away while the computer completes the shutdown process.
Is there any setup options or apps. that will allow this?
Thanks, Joe
(new to the mac)
MBP Mac OS X (10.4.6)Well hello there, and welcome to Macintosh.
Unfortunately you can't change anything to stop this from happening. The shutdwn process goes about its business killing processes and applications that have been running. The sleep process interrupts ALL business going on in the OS, and puts the machine into low power mode, as it is not aware of the nature of the running processes (in this case, the shutdown process), knowing only that they must be slept and the machine dropped into sleep mode. You gotta wait it out before you close the lid.
I would suggest sending a message in OS X feedback requesting this as a feature!

HP PHOTOSMART ALL-IN-ONE 5510 WONT PRINT AFTER GOING TO SLEEP MODE
My printer model:
HP PHOTOSMART ALL-IN-ONE 5510 B111A
Problem:
Printer goes to sleep mode. After 25-30 minutes the wireless connection between the PC and the printer breaks. Blue Wireless light is on even at the sleep mode and I can see that the printer is connected to my router and there is internet connection. HP Print and Scan Doctor sees the printer but I cannot awake the printer unless I restart it.
What I have tried so far:
I have tried all the solutions hp.com offered including; reinstalling driver, updating printer software, setting static IP to printer, setting static DNS servers, using HP Print and Scan Doctor.
I have seen people asked about this question before and there was no solution. I really need HP help!
This question was solved.
View Solution.Let’s try this. Verify in the printer that 'Auto Off' is disabled. Set a static IP in the printer outside the DHCP range of the router. Use a fixed wireless channel like 1,6 or 11, never 'auto', try channel 1 first then the rest. Set router to 20Mhz only, or 145Mbps depending on router. Always use WPA2-AES encryption. Power off both. Power on router wait 3 mins. Power on printer and verify it reconnects to router. Now try.
Say thanks by clicking the Kudos Thumbs Up to the right in the post.
