These parameters are basically related to performence problem.Just check the extended memory uses in ST02. In any time it should not be more then 90%. Whenever a memory uses is high and program are not able to execute in a given dialog Nondialog heap area & extended memory area, workprocess gone into PRIV modeI think you should increase some parameter value.ztta/rollareaztta/shortareardisp/ROLLSHMrdisp/PGSHMrdisp/PGLOCAL.em/initialsizeMB.em/maxsizeMB.em/blocksizeKBem/addressspaceMBztta/rollextensionabap/heapareadiaabap/heapareanondiaabap/heapareatotalabap/heaplimitRegardsSubhashabap/usepaging. Hi,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.
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? A work process enters PRIV mode when either a) extended memory is exhausted. Jul 17, 2016 The work process cannot be terminated by the parameter “rdisp/maxwpruntime” PRIV when a work process enters PRIV mode, it remains connected to the user until the user ends the transactions or it is timed out by the system due to the memory.
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/wpprivmaxno.
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 51If more than (n) dialog work processes are active and the time span set in parameter rdisp/maxprivtime (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.ThanksTanuj(.Award point if useful.). As most/all of your WP's are in PRIV it is not that a couple of people are using more than their allowed allocation of extended but that extended memory has become exhausted. This you can see easily in ST02 and the history in ST02 should show how often your extended memory is hitting 100%.
This must be resolved, it is a poor and potentially dangerous situation for your system.This quick answer is to increase em/initialsizeMB. If you need a more detail investigation, let me know.Edited by: Graham Newport on Mar 24, 2008 11:58 PM.
BlackBerry has certainly been witness to better days, but fans of the once iconic brand had something to get excited about when the company announced its first Android smartphone last year. The offers specifications that are at par with high-end competition, and the slew of BlackBerry features that are baked in to the software experience not only serve to evoke a sense of nostalgia, but actually prove to once again be very useful. The Priv may not be perfect, but is a fantastic first attempt, and definitely provides reason for us to be excited about what is in store.As is the case with most current generation smartphones and tablets however, the BlackBerry Priv is not without its issues.
Which is why we’ve rounded up some of the common problems faced by Priv owners, and offer potential solutions on how to fix them! BlackBerry has been sending out OTA security updates monthly, but users have found that following the December update, the device lands on an error page after reboot, and continuous attempts at restarting the phone leads to the same error. Even more users have faced this problem following the January security updates.Potential solutions:. The good news is that the solution that has worked for most users is very simple, and requires only a Hard Reset of the device, by pressing and holding the volume up and down keys simultaneously for at least 10 seconds, when you reach the error screen. This seems to fix things and everything is fine on the next reboot, with all the data and information safe.Problem #2 – Top left of the display stops responding to touchMany users have found that the top left of the screen stops responding to touch, making certain icons or the back arrow in apps unusable.Potential solutions:. This issue was seen recently with the as well, in which the top right of the display stopped responding instead, but, the app causing the problem in both instances is the same, with the Facebook Messenger app at fault once again. Users have found that uninstalling the app solves the issue right away.
Hopefully, a future update of the app will address this problem. However, some users have found some other rogue apps to be causing this issue as well. Boot the device into Safe Mode and see if the issue persists. If it doesn’t, remove any recent applications you may have installed before the issue showed up, and see if that fixes it. If you absolutely cannot remove the app at fault, a temporary fix seems to be a Soft Reset, after which, the issue goes away, at least for a few hours.Problem #3 – SIM card errorsMany users have found the “No SIM card” error to pop up intermittently multiple times during the day.
Some users have also found a “New SIM detected” message to come up instead, with this requiring a reboot before the device recognizes the SIM again. There seems to be multiple hardware and software related issues that are causing this problem.Potential solutions:. First, check to make sure that the SIM card itself isn’t faulty, by checking it with another device. Most network carriers will offer a replacement SIM for free, or with a minimal fee, and some users have found the issue to go away with a new card.
Some users have found that the SIM card tray is at fault, and can be quite loose in the slot, and pushing the slightly firmly into the slot seems to work. Pressing the top of the phone where the SIM tray is located when taking the device out of the pocket or or a holster case seems to cause the problem. You can try and be careful to avoid reproducing the issue, but if it gets very persistent, the only option here will be to pick a replacement smartphone. In some cases, this may also be a software issue. Some users have found that going to Network Settings and choosing “4G LTE & 4G & 3G,” instead of the other options, seems to fix the problem.Problem #4 – Camera cannot focusSome users have found that their device camera now seems to be out of focus all of a sudden.Potential solutions. Some users have found the device camera to be out of focus, but this usually occurs when the phone or camera has been in use for a while, resulting in a warm phone.
Turn off the camera app, let the device cool down, and this seems to take care of the problem for these users. However, faulty/damaged hardware may be the cause, and the only solution in this case is to pick up a replacement device. To check for hardware damage, download the, and run the relevant tests, in this case, the camera test and the gyroscope test.Problem #5 – SMS/MMS issues with Priv on AT&TA known issue for BlackBerry Priv owners using the AT&T network is troubles with sending/receiving group messages or photos.Potential solutions:. Some temporary workarounds, like using Hangouts for SMS/MMS, have worked for some users. However, as mentioned, this is an issue known by AT&T, and requires disabling HD calling. As is the case with any new device, you may find yourself facing some connectivity issues with Bluetooth and Wi-Fi.Potential solutions:Wi-Fi issues. Turn the device and the router off for at least ten seconds, then turn them back and retry the connection.
Go to Settings – Power saving and ensure that this option is turned off. Use the to check how crowded your channel is, and switch to a better option. Forget the Wi-Fi connection by going to Settings – Wi-Fi and long tapping the connection you want, then selecting “Forget”.
