Performance Problems after migration to unicode

Hello,
we have migrated our crm40sp6/msa-system to unicode. But now system is very slow, and the greater problem is that when we replicate via modem and conntrans I often get connection error while receiving data. And when I receive some data, the mas-client is very slowly to import the data. I often do not get all data so that I have to replicate repeatedly.
Before unicode I didn't have this problems.
Does anyone have the same experince with crm/msa-unicode ?

Hi Gerd,
You have mentioned that the system is migrated to CRM 4.0 unicode. What do you mean by unicode. Are u able to see in the MAS client several languages in the same screen in CRM 4.0.
I heard that CRM 4.0 is a unicode system but I don't think still you could see different languages in the same screen. For eg display japanese, chinese and english in the same screen.
For your information search on OSS notes you will get a note for Unicode which needs to be applied. Also in general the unicode solution is comparitevly slow when data is transfered from Middleware to mobile client via conntrans as the data is transfered in the XML format which contains more information than the regualar RFC format.

Serious problem after migration assistant - any ideas?

Hi folks-
I bought an iMac this weekend and for various reasons did not configure with data from my MacBook Pro when I first turned it on, but waited until two nights ago to use Migration Assistant to transfer all but users.
I updates both machines fully with Software Update first. MigAsst went fine until I hit the begin option and after a few minutes the iMac told me there was a problem with my MacBook Pro (MBP). I quit MigAsst on the iMac but even after an hour I couldn't escape it or quit the MBP, so shut down using the power button.
When I restarted, I had a black screen with lighted keyboard and startup chime. I hard-restarted, same thing happened. Third time, I got the grey apple window with no apple for about ten minutes, then a light blue screen with the spinning spokes (not the rainbow) and a slightly darker window with no spokes. The two blue windows alternated back and forth for maybe 8-10 seconds each endlessly until I restarted.
Since I live about 4 hours from the nearest Apple store and tech support was already closed for the evening, I restarted from the Snow Leopard disk and repaired permissions (there were many repairs) and repaired the disk (was told it was fine). I restarted and got the grey-blue-blue cycle again.
I reinstalled the OS from the Snow Leopard disk and everything worked fine - I ran as many tests as I know how to, even perturbed the casing slightly wondering if it was a loose video card wire or something. Nothing. It all worked fine for several hours until after the second Software Update (which as I recall was only Java and iTunes), and now all I get is the black screen again. Also, now the green light on the power cable is not glowing even though the battery reads as fully charged and the keyboard and startup chime are all hunky dory.
I'd think it was a video card issue, but there are too many incongruous symptoms. If I could at least start up from the OS disk again I could get my data off... Any ideas, diagnoses or suggestions would be much appreciated.
With gratitude and blessings.

The problem is described in a different post as well, and it is considered to be answered. However, the answers are not very satisfactory because they are complicated.
The underlying problem is that MacOS is looking for a FileVault user, while after migration the user files are actually not within a FileVault bundle.
I believe that there must be a setting to change the login properties for the user to not look for a FileVault user, but for a plain, non-encrypted user. So please, somebody from Apple answer this questions!
Command line very welcome, because I only have a command line user right now. And oh, my MBA didn't ship with a boot DVD so I don't even have the chance to reinstall my system easily. Also, getting my data out of the FileVault on my current machine, transfering everything again (almost 250 GB) and then putting them back into FileVault seems a bit too much effort for what appears to be a simple bit set somewhere…

Performance problems after EHP4

Hello,
We have a small problem.
After installing EHP4 for ERP and EHP1 for Netweaver 7 on AIX Oracle installation, an increase in dialog response time is reported.
We upgraded last September 2009, and from then and to now, we have gone from an average of 800ms to 1200ms in dialog response time.
When we analyze transactions, there is no specific transaction that is the cause, it looks more like an allover trend, that the system in general has become slower.
When we look at fx. Earlywatch reports, it is quit obvious, that the u201Cproblemsu201D started just after implementing the EHP.
We are attacking this on several fronts, and I am looking on the sap basis part.
I was not a part of the upgrade team, so what I am looking into, is weather maybe some notes has been forgotten or something else. I am especially interested in notes and steps that should have been performed on Oracle, in connection with the EHP upgrade.
Is there anybody in here that have experienced similar problems, after applying EHPs?
Best Regards,
Kenneth

Hi Kenneth,
In which area that you are having much interval in total rsponse time? If it is looking under DB time may be cause with Oracle bug fixes..check your all Oracle patches(mainly related to performance).
And explore the DB version and patch list that presently you had.

Performance problems after installing XP Service Pack 3

Hello,
After upgrading my client XP-machine to Service Pack 3, I have serious performance issues working with ApEx. Firstly, establishing the connection to the ApEx Workspace and then logging in both are very slow. Navigating through the workspace works fine, however when I then open any page for editing and/or try to run it, again it is very slow. As we work with PL/sql Embedded gateway I have changed the parameter SHARED_SERVERS to 10, but this did not make any difference. Remotely connecting to this server in other ways such as ping, connecting to xmlpserver, mapping network drives and connecting to the database all work fine.
My collegues also working witk Service Pack 3 have no performance issues. However when I performed a rollback of the XP Service Pack 3, the performance issue was gone!
Does anyone know of any issues similar to this problem?
Regards,
Ben van Dort

This issue is probably related to an update of InternetExplorer by Service Pack 3. Working with Firefox instead of IE gives no performance problems whatsoever.
Version of IE after Service Pack 3: 6.0.2900.5512.xpsp_sp3_gdr.080814-1236CO

Serious performance problems after updating from 10.5.6 to 10.5.7

I've got a Macbook Pro C2D 15" (late 2006). After updating the system from 10.5.6 to 10.5.7 and quicktime to 7.6.2, I experience serious performance problems which I have never seen before:
-From time to time, kernel_task has peaks in activity monitor (consumes a lot of CPU). In that moment, the mouse hangs for a short moment and audio playback is distorted/has drop outs.
-Recording audio consumes a lot of CPU (independent of the audio application).
-Video playback consumes a lot of CPU, regardless if I use VLC or the quicktime player.
Any idea what could be done? Thanks in advance.

After a few days of using CoolBook I report that my 1st generation MacBook Air is now reliable and never overheating, regardless of environment conditions.
I must point out that I do believe that it really is something new in 10.5.7 that is causing this problem as my environmental conditions have not changed and even Summer in Dublin still sees temperatures no more than 72F/22C. I am now in Madrid, where the environment is quite different, and I am still having no problem with kernel_task spinning.
I plan on reporting my problem to Apple anyway and being aggressive about the issue as MacLovinRanga did in this thread (http://discussions.apple.com/thread.jspa?messageID=9647353#9647353). Perhaps many/all of those of us having this problem will obtain new MacBook Airs.

3D performance problems after upgrading memory

I recently purchased an additional 2GB of memory to try and extend the life of my aging computer. I installed the memory yesterday and Windows seems to recognize it (reporting now 3.3GB) but when I dropped into WoW (pretty much the only game I have) the 3D performance was down from the usual 60FPS @ 1600x1080 to a bleak 20 (at best) and the CPU utilization went to about 80% on both cores (with ~20% kernel usages). Basically WoW was being software 3D rendered!!!
I went through the usual reinstall drivers, reboot, etc... and couldn't find a fix. I powered down, pulled out 2 of the memory sticks, booted up, and dropped into WoW - it ran at the full 60FPS and CPU utilization was very low (i.e. back to GPU Hardware 3D rendering). I powered down again, swapped the 2 sticks for the other 2 sticks, booted up, and dropped into WoW - again it ran 100% fine. So I powered down, put all four sticks in, booted back up, and when I dropped into WoW it was running in the software 3D rendering mode (20FPS at best and High CPU/Kernel usage).
I've tried the /PAE option in boot.ini - no joy. I've tried /MAXMEM = to 3300, 3072, 3000, and even 2048 - no joy in any of those cases. Has anyone seen anything like this before? Or have suggestions to fix (other than going to Win7-64)?
All info in signature is up to date.
Thanks in advance for any help!

PAE or Physical Memory Extension will not do anything as Microsoft has castrated this feature to such an extend that it has nothing to do with memory addressing anymore when in comes to Windows XP:
http://en.wikipedia.org/wiki/Physical_Address_Extension#Microsoft_Windows
Quote
Windows XP Service Pack 2 and later, by default, on processors with the no-execute (NX) or execute-disable (XD) feature, runs in PAE mode in order to allow NX. The NX (or XD) bit resides in bit 63 of the page table entry and, without PAE, page table entries only have 32 bits; therefore PAE mode is required if the NX feature is to be exploited. However, desktop versions of Windows (Windows XP, Windows Vista) limit physical address space to 4 GiB for driver compatibility reasons.
The feature is already automatically enabled. But since is original function (Address Extension) does no longer exist when it comes to the desktop versions of Windows XP, it won't really do anything you would ever notice.
About the /MAXMEM Switch: In Windows 32bit operating systems, every process is limited to 2GB of memory. The point of the switch is to allow certain applications (or their run-time process) to occupy a higher amount of system memory than 2GB. However, the culprit here is that only those applications are able to utilize this ability that have been programmed (or compiled) accordingly. A special flag (large memory aware) has to be implemented. Otherwise, these application will be restricted to 2GB even though the /MAXMEM Switch has been set to extend the 2GB limit to 3GB. Most 32bit applications come without the "large memory aware" flag and that is why usually, settings the switch won't change anything.
In any case, it is unlikely that /PAE (even if it would not be castrated) and /MAXMEM would have an impact on your actual issue because I doubt that it has much to do with either memory adressing or the memory limit of an indiviual Windows process.

the 3D performance was down from the usual 60FPS @ 1600x1080 to a bleak 20 (at best) and the CPU utilization went to about 80% on both cores (with ~20% kernel usages).
There are a couple of hardware based explanations to consider here. Let's start with the most obvious one:
1. 975X Memory Controller
The main reason that the system chooses to automatically set the Memory Speed to DDR2-667 even though DDR2-800 modules are installed, is that by design the memory controller of the Intel 975X Chipset does not natively support DDR2-800 modules, but
>>Intel® 975X Express Chipset Datasheet - For the Intel® 82975X Memory Controller Hub (MCH)<< [Page 20]
This means, that from the point of view of the memory controller, operating the memory @DDR2-800 actually means overclocking it (with all potential side effects).
Basically, if your initial problem disappears as soon as you reduce the memory speed to DDR2-667, the design limitation of the memory controller may explain your findings.
2. Different memory modules
If I read your signature correctly, you are actually mixing two different kits/models of RAM (CM2X1024-6400C4DHX and CM2X1024-6400C4). This can work of course, but in practice it not necessarely does under all circumstances.
This list (-> http://ramlist.i4memory.com/ddr2/) indicates that there are at least 14 different module types/revisions of Corsair DDR2-800 / CL4 modules that utilize a wide range of different memory chips (Elpida, ProMos, Micron, Infinion, Powerchip, Qimonda, Samsung, Infinion etc.). Even though the superficial specifications for these chips appear to be pretty similar (DDR2-800 / CL5 / CL4), this does not necessarely mean that the modules will respond to the same operating conditions in the same way. There may be small difference in sub-timings/sub-latencies and/or the general responsiveness of the ICs which may affect the operating behaviour of the memory controller (which by the way also includes the PCI-Express interface which your video card is hooked up to).
And again: If running the system @DDR2-667 solves your issue, the possible explanation is that higher clock speeds may amplify (or trigger) potential performance problems that could have to do with the use of non-identical memory modules.
Furthermore: It is also possible that the memory controller's design limitations and the potential compatibility problems that may be attributed to mixing different modules types may reinforce each other in terms of reduced system performance.
3. The BIOS may have an impact as well
There has been known issue with the use of certain video cards in conjunction with 4GB of system memory on this mainboard:
https://forum-en.msi.com/index.php?topic=107301.0
https://forum-en.msi.com/index.php?topic=105955.0
https://forum-en.msi.com/index.php?topic=99818.msg798951#msg798951
What may have come out as graphics/display corruption in earlier BIOS Releases may come out as reduced system performance when using the latest BIOS Release. Of course, this is hard to prove, but I thought I'd mention it anyway. May I ask what amount of video memory your card has onboard?
Fortunately, there is a BIOS version that you could consider to try in this matter. It is not only the last BIOS Release that could be used in order to avoid the corruption issue, but it is (in my oppionion) the best BIOS Version that was ever released for the 975X Platinum PUE Mainboard: W7246IMS.716 [v7.1b6]. I have been using this mainboard for almost two years and have tested almost every BIOS Release that ever came out and I always went back to v7.1b6 as "ground zero".
It will properly support your E6600 (so you don't have to worry about that) and as far as I remember, there are no known compatibility issues with other components. So maybe, you want to give this a shot.
The bottom line is that in a worst case scenario, the problem you describe could be caused by all of the above things at the same time. You cannot really do anything about the 975X Chipset Specifications and the only way to rule out explanation #2 is to test modules that are actually identical (same model number, revision and memory chips). A test of the 7.1b6 BIOS Release is something you should consider. It may be the only way to test the BIOS Hypothesis.
This post turned out to be longer than I intended, but then again, I am well-rested after a good sleep and the wake-up coffee is kicking in pretty good.

2 Problems after migration Project Server 2007 to 2010

Hi Everyone!!
I have 2 issues after migrate MS Project Server 2007 to Project Server 2010, in fact i had a lot issues, but i can solve almost all, so after solve all issues, just is pendings 2 issues very rare:
Backgrounds:
Migrated from: Windows Server 2008R2 - SQL Server 2008 R2 - Proejct Server 2007 with WSS 3.0 - All updates are up to date (CU is up to date) and all platform is ok
To: Windows Server 2008R2 - SQL Server 2008 R2 - Project Server 2010 SP2 - SharePoint Server 2010 SP2 - All updates are up to date (CU is up to date) and all platform is ok
3 Servers in the Farm, ----> 1WFE-1WAPP-1DB
Issues:
In the Project Center, some migrate Project don't show the icon with image about project documents, risk and issues although that project effectively have documents , risk and issues
In "Server Settings" , in section "Operational Policies" in "Project Sites" almost all projects don't show the URL with Project Site
For the issues 1 and 2, i tried some things:
Re publish all projects (approx 700 projects) with a script via PowerShell available in technet
Run the Wizard Again
Rebuild Solution
Restart the all Servers in the Farm
Restart Services ----> IIS - Project EventService - ProjectQueue - SharePoint Timer
and i can't solve it yet!!!
Please Any Ideas?

Have you restored content DB successfully?
for point 2 have you performed:
have you synchronized project site under server setting --> operational policies --> Bulk Update Project
Sites
http://pwmather.wordpress.com/2012/10/08/projectserver-2010-bulk-update-project-site-issue-ps2010-msproject-sp2010-sharepoint/
after doing this publish all the project which are having issue it may solve your 1st issue.
You can check if below condition is applies to you (PWA 2007)
You may need to use the WSS site re-linker tool –
now built in to Server Settings in PWA as “Bulk Update Project Sites”. If you have changed URL die to a different port then re-linking should get your sites in order. In upgrade scenarios the “Previous Site Path” Web application might show as a GUID
in the drop down – however it still works and will re-link the sites.

Do you have the problem with all JSP pages, or only a few of them ?
Does it happen in the Embedded OC4J only ?
Could you try to deploy your application in the Standalone OC4J and test it from there ?
I had a similar issue where the Embedded OC4J was unnable to run big JSP pages.
There was no problem with the Standalone OC4J.
Hope this helps,
Didier.

Major permissions problems after migrating to new iMac

Hi, I am very new to this and need some help. Have been using a MacBook pro for the past year to synch iPods/iPads that are used within our school. Purchased an iMac and proceeded to migrate users/files etc. After migrating I have had major problems with iTunes. My iTunes library is visible but I cannot synch any devices, have tried verifying permissions and fix permissions but to no avail. Any help would be very much appreciated.

Did you instal the program again, or try to migrate it from the old system (not a good idea)? I would run the installer again and it should correct the problem -- the Proximity dictionary for English (and probably others) is apparently not installed correctly.

Performance problems after Update from 7.6.00.37 to 7.6.03.15

Hi,
after the Update from 7.6.00.37 to 7.6.03.15 in our live system we noticed a lot of performance problems. We have tested the new version before on our test system, but there don't noticed effects like this.
We have 2 identical systems (Opteron 64 bit, openSuse 10.2) with log shipping between them. We updated first the standby system, switched from online to standby (with copy of cold log) and started the new server as online system. After that we run a complete backup (runtime: 1 hour) for starting a new backup history and for activating autolog. Then
With the update we changed USE_OPEN_DIRECT to YES, but the performance of the system was very slow afterwards. After the backup it remains at a high load average (> 10, previous system had about 2-4), with nearly 100% of CPU usage for the db kernel process.
Next day we switched USE_OPEN_DIRECT back to NO. The system first runs better, but periodically rises up to a load average of 6 and slow down the performance of various applications (somebody says about 10 times slower). Here we also noticed a high usage (now 200-300%) of the db kernel process.
Our questions are:
1. Has something basically changed from 7.6.00.37 to 7.6.03.15, so that our various applications (JDBC, ODBC and Perl/SQLDBC partially on old linux systems with drivers from 7.5.00.23) don't reach same performance as before?
2. Are there any other (new) parameters, which can help? Maybe reducing MAXCPU from 4 to 3 for reserving capacities for the system (there is only one maxdb instance running)?
3. Is the a possibility to switch back to 7.6.00.37 (only for worst case)?
I have made some first steps with x_cons, but don't see any anomalies on the first look.
Regards,
Thomas

Hmm... that is really odd. When using USE_OPEN_DIRECT there is actually less work to do for he operating system.

Well of course there are bugs that have been found inbetween the release of both versions, but I am not aware of something like the performance killer.
We will have to check this in detail here.

Well - then I guess 'looking at the system' won't bring you far...

Great - let's see the warnings you get.
Let us also see the DB Parameters you set.

With the old version we had no problems with missing indexes or the general performance. Unfortunatly it is very difficult to extract some sql statements out of the JBoss applications. But even simple queries (without any join) runs slower, when the load average rises over 4-5.
Hmm... the question here is still, if the execution plans are good enough to meet your expectations.
E.g. for tables that you access via the primary key it actually doesn't matter how many rows a table has (not for MaxDB at least).

Sounds like the I/O is your most suspect aspect for overall system performance...

Ok - so this is next to no testing at all when it comes to performance.
> An UPDATE STATISTICS over all db users seems to change nothing. At the moment the system remains markedly slow and we are searching for reasons and solutions. Another attempt will be the change of MAXCPU from 4 to 3.
Why do you want to do that? Have you observed any threads that don't get a CPU because all 4 cores are used by the MaxDB kernel?

Problems after migration from CS5 to 5.5 with Blackmagic Card

Hello forum,
we have an problem after an optimal migration from cs 5 to 5.5 projects.
different: there is an bm hd extreme 3d card in the system.
We are aware of the issue that there has to switch to BM player an the Timleinl settings to BM
But there is still a problem: we are not able to view the ingested material in the source viewer,
because there is another overlay - form the background or sometheing else - see attached photo.
We add new drivers for graphics/BM and patches for CS 5.5
None of these problems by creating new projects.
Also the applications also hangs after we try to close,
many thanks for your answers - Sven.

No reason to ask the same question twice. Just be aware that there are German forums as well.
Your problem is probably in the BM drivers.

Ofgtel65.pll , CGDV$REF_CODES.SOFT_VAL problem after migrating to 10g

Hi,
We have migrated from Oracle 9i to 10g and
In 'OAS904' , i have used CGDV$REF_CODES.SOFT_VAL to populate a field with a meaning via a dynamic list in one of the FORM and if I query the form by giving a value and press F12,all fields are populating , its working fine but the same thing is not working after migrating the FORMS application to 'OAS10.1.2'. If I query the form by giving a value and press F12,its showing error like "FRM:40201 Field must be entered" for that particular field because that field is not populated and also a required field in the form.
Actually , this form is generated by designer.If i open the form using forms builder, i can see the auto generated code like 'POST-QUERY', in that CGDV$REF_CODES.SOFT_VAL is used to retrieve the meaning.
Note : ofgtel65.pll points to QMS_REF_CODES instead of CG_REF_CODES.
Am using headstart6.5.4.0 .
The generated form having post_query with the following code
CGDV$REF_CODES.SOFT_VAL(P_VALUE=>curr_value, P_MEANING=>l_meaning, P_DOMAIN=>l_domain, P_VAL_CODE=>TRUE);
But in the ofgtel65.pll ,
the soft_val method will have a query that refers to QMS_REF_CODES .But my meanings are present in CG_REF_CODES.
Any help would be of great help. Thanks in advance.
Regards,
Tharini.

Is this a Designer generated Form ? You may want to ask the question on that Forum too.

Strange Calendar sync problem after migrating to iOS5

Hello all,
I posted my problem as an "me too" reply to somebody else's thread but think it got a bit lost there.
Since I can't solve this problem I decided to make a new thread.
The problem:
After upgrading my iPhone4 to iOS5 I have a strange calendar syncing issue such that existing entries from one calendar (I've got two, see below) are duplicated on the other .... but only on the iPhone, not on the calendar server (Lotus Notes) itself!
As I couldn't find a normal solution to this problem (already removed the complete Lotus Notes traveler account from my iPhone and reinstalled it again, to no use: the duplicates pop up again) I finally decided to start removing the duplicate entries on my phone. To my surprise however they popup again!!!!!
I added a new entry to the original calender to see whether that one would popup in the other as well but this didn't happen.
It looks to me it must be something wrong on my iPhone as the "duplicates" do not show up in the calender database on the server (using Lotus Notes PC client) nor its replicas.
The configuration:
I sync with two calendars on my iPhone:
- gmail calendar for my private
- lotus notes server (traveler exchange) for my work.
The gmail calender also syncs with my desktop client (outlook 2010) via a small application "gSyncit".
This all worked like a charm on iOS4.
No matter where I modified, deleted or added entries (not only calendar, also contacts and mail) it all stayed perfectly in sync!
Does anybody out here noticed the same and/or has a solution to this?
BTW: I haven't activated iCloud for the calendar/mail/contacts (yet) ...

OK,
I found out what was wrong myself.
In the end it turned out that it had nothing to do with the iOS5 upgrade itself.
In case somebody else stumbles accross this very same problem, here's what was going on:
- Within the latest lotus notes client (on PC) the user has the possibility to display (read-only) external calendar contents (e.g. google's calendar).
- When setting this up you need to supply your external calendar's login/password information and next to that
- also have the possibility to select "View this calendar when offline or on a mobile device"
It was this setting (which I probably accidentally enabled) causing the "issue". Deselecting this option made my duplicate entries disappear on my phone.
