Performance issue in KM as a WebDAV client
Hi all,
I have configured KM as a WebDAV client.But there is a performance issue.Whenever i try accessing the folder,its been cached.
Can some suggest how to avoid caching of data everytime.
I am using a memory cache.
thanx and regards,
anuradha
Hi Anuradha,
well, it is intended that the data is being cached...
What is wrong with caching in your scenario?
What are the settings for your WebDAV-RM in KM (especially "Cache Timeout")?
And what are the settings for your memory cache ("Default Time-to-life" and "Restart lifetime on access")?
Best regards,
Paul

Issues with Finder as a WebDav client
I have written a WebDav server that can be integrated into my iPhone app so as to allow some files to be transferred to and from the application. (I've already been through a long discussion as to whether or not Apple will allow this 'feature' but that is not the subject of this question).
When I use Finder as the client for my testing (both on the simulator and the device itself) I get the first part of the connection going and then Finder gives me an error that the server cannot be found on the network - even after it has already completed 2 request/response transfers with the server.
When I use CyberDuck as the client, it all works well and I can perform all of the interactions correctly.
I've used the 'PacketPeeper' application to look at the information passing between the client and the server and I can see no (significant) difference between the clients for the actual packets - its just that Finder simply stops sending sending packets except for one that has no payload and includes the 'FIN' flag.
The 'significant' word is used above because the XML data that is transferred back from my server to the client can either have all tags appended directly to the prior one, or can have line terminators and spacing added to the entire packet. Neither form makes any difference to CyberDuck or to Finder for the transfers that do occur. However when I monitor Finder talking to the 'AirShare' application, I see that AirShare formats some but not all of the XML - however the communication continues between Finder and AirShare. My understanding is that the formatting of the XML should make no difference to the information being passed.
Can anyone please tell me where I should be looking for a difference that is making my server fail with Finder?
I could simply carry on and blame a bug in Finder, but I really want the let Finder be a client as it will be available to all OS X-based users but other WebDav clients may not be.
Thanks
SusanFound the problem and I'm describing it here in case it is of use to others.
The 'obvious' symptom was that Finder was sending the request for the 'OPTION" and 'PROPFIND' information and then displaying a popup dialog box saying that the server could not be found on the network.
The 'non-obvious' symptom was that there was an entry in the console log that the specified root was a file and not a directory, and giving the name of the file that the error was encountered (webdav_network.c) and the line number.
The problem turned out to be that when I was creating the XML response data header, I accidentally said "encoding=utf8" instead of "encoding=utf-8".
Looking at the code in webdav_network.c (which is part of the Darwin code set and therefore available on the Apple developer site) I found the place where the console log line was generated which was followed by a return status of 'no device' which must be interpreted by the rest of the finder as no server.
Tracing back a little further into the code (webdav_parse.c)I found where the XML was actually being parsed (using the core foundation event-driven XML parser functions) and noticed that there was no error checking code around the actual parse itself and so no error code was being returned. When I copied the appropriate parts of the code into my own program (so that I could debug it) I found that it was returning an error and the error was quite explicit: unrecognised encoding!
The parsing failure meant that the callback routines were not being called and so none of the flags and values were being set correctly. Because no error was being returned, back in the webdav-network.c file the parse was assumed to be successful and the incorrect parse state information was therefore being mis-interpreted (a check to make sure that the 'directory' flag had been set was failing which lead to the 'not a directory' console message).
If only the code had been written to do a bit more error checking and had returned more sensible error messages...!!!!!

N8 email client performance issue
The email client on the N8 mostly works OK, but the performance is terrible when trying to reply to an email that is "long". Actually there really doesn't have to be that much text in the previous message(s) when the client starts to be really really slow. When typing, the lag is really making the typing almost impossible.
Is there plans to improve the performance? Will the Anna update improve the client? N8 isn't the best hardware out there, but still it has plenty of power to handle large emails also. This can be lightly tested using some webmail with the phones browser. When typing a reply to a long email there is no problem.
Others having performance issues when trying to reply to a long email?Same here, not only answering large emails, sending email with attachments is about the same. I am having sync problems too, Messaging looks erratic.

Performance issues with LOV bindings in 3-tier BC4J architecture
We are running BC4J and JClient (Jdeveloper 9.0.3.4/9iAS 9.0.2) in a 3-tier architecture, and have problems with the performance.
One of our problems are comboboxes with LOV bindings. The view objects that provides data for the LOV bindings contains simple queries from tables with only 4-10 rows, and there are no view links or entity objects to these views.
To create the LOV binding and to set the model for the combobox takes about 1 second for each combobox.
We have tried most of tips in http://otn.oracle.com/products/jdev/tips/muench/jclientperf/index.html, but they do not seem to help on our problem.
The performance is OK (if not great) when the same code is running as 2-tier.
Does anyone have any good suggestions?I can recommend that you look at the following two bugs in Metalink: Bug 2640945 and Bug 3621502
They are related to the disabling of the TCP socket-level acknowledgement which slows down remote communications for EJB components using ORMI (the protocol used by Oracle OC4J) to communicate between remote EJB client and server.
A BC4J Application Module deployed as an EJB suffers this same network latency penalty due to the TCP acknowledgement.
A customer sent me information (that you'll see there as a part of Bug# 3621502) like this on a related issue:
We found our application runs very slow in 3-Tier mode (JClient, BC4J deployed
as EJB Session Bean on 9iAS server 9.0.2 enterprise edition). We spent a lot
of time to tune up our codes but that helped very little. Eventually, we found
the problem seemed to happen on TCP level. There is a 200ms delay in TCP
level. After we read some documents about Nagle Algorithm, we disabled a
registry key (TcpDelAckTicks) in windows2000 on both client and server. This
makes our program a lot faster.
Anyway, we think we should provide our clients a better solution other than
changing windows registry for them, for example, there may be a way to disable
that Nagle's algorithm through java.net.Socket.setTcpNoDelay(true), in BC4J,
or anywhere in our codes. We have not figured out yet.
Bug 2640945 was fixed in Oracle Application Server 10g (v9.0.4) and it now disables this TCP Acknowledgement on the server side in that release. In the BugDB, I see backport patches available for earlier 9.0.3 and 9.0.2 releases of IAS as well.
Bug 3621502 is requesting that that same disabling also be performed on the client side by the ORMI code. I have received a test patch from development to try out, but haven't had the chance yet.
The customer's workaround in the interim was to disable this TCP Acknowledgement at the OS level by modifying a Windows registry setting as noted above.
See Also http://support.microsoft.com/default.aspx?kbid=328890
"New registry entry for controlling the TCP Acknowledgment (ACK) behavior in Windows XP and in Windows Server 2003" which documents that the registry entry to change disable this acknowledgement has a different name in Windows XP and Windows 2003.
Hope this info helps. It would be useful to hear back from you on whether this helps your performance issue. -
Performance issues with the Vouchers index build in SES
Hi All,
We are currently performing an upgrade for: PS FSCM 9.1 to PS FSCM 9.2.
As a part of the upgrade, Client wants Oracle SES to be deployed for some modules including, Purchasing, Payables (Vouchers)
We are facing severe performance issues with the Vouchers index build. (Volume of data = approx. 8.5 million rows of data)
The index creation process runs for over 5 days.
Can you please share any information or issues that you may have faced on your project and how they were addressed?Check the following logs for errors:
1. The message log from the process scheduler
2. search_server1-diagnostic.log in /search_server1/logs directory
If the build is getting stuck while crawling then we typically have to increase the Java Heap size for the Weblogic instance for SES> -
Performance issues with FDK in large XML documents
In my current project with FrameMaker 8 I'm experiencing severe performance issues with some FDK API calls.
The documents are about 3-8 MBytes in size. Fortmatted they cover 150-250 pages.
When importing such an XML document I do some extensive "post-processing" using FDK. This processing happens in Sr_EventHandler() during the SR_EVT_END_READER event. I noticed that some FDK functions calls which modify the document's structure, like F_ApiSetAttribute() or F_ApiNewElementInHierarchy(), take several seconds, for the larger documents even minutes, to complete one single function call. I tried to move some of these calls to earlier events, mostly to SR_EVT_END_ELEM. There the calls work without a delay. Unfortunately I can't rewrite the FDK client to move all the calls that are lagging to earlier events.
Does anybody have a clue why such delays happen, and possibly can make a suggestion, how to solve this issue? Thank you in advance.
PS: I already thought of splitting such a document in smaller pieces by using the FrameMaker book function. But I don't think, the structure of the documents will permit such an automatic split, and it definitely isn't an option to change the document structure (the project is about migrating documents from Interleaf to XML with the constraint of keeping the document layout identical).FP_ApplyFormatRules sounds really good--I'll give it a try on Monday. Wonder how I could miss it, as I already tried FP_Reformatting and FP_Displaying at no avail?! By the way, what is actually meant with FP_Reformatting (when I used it I assumed it would do exactly what FP_ApplyFormatRules sounds to do), or is that one another of Lynne's well-kept secrets?
Thank's for all the helpful suggestions, guys. On Friday I already had my first improvements in a test version of my client: I did some (not all necessary) structural changes using XSLT pre-processing, and processing went down from 8 hours(!) to 1 hour--Yeappie! I was also playing with the idea of writing a wrapper to F_ApiNewElementInHierarchy() which actually pastes an appropriate element created in a small flow on the reference pages at the intended insertion location. But now, with FP_ApplyFormatRules on the horizon, I'm quite confident to get even the complicated stuff under control, which cannot be handled by the XSLT pre-processing, as it is based on the actual formatting of the document at run-time and cannot be anticipated in pre-processing.

Performance issues with SAP BPC 7.0/7.5 (SP06, 07, 08) NW
Hi Experts
There are some performance issues with SAP BPC 7.5/7.0 NW, users are saying they are not getting data or there are some issues while getting data from R/3 system or ECC 6.0. Then what things do I need to consider to check, such as what DataSources or Cubes I need to check? So, how to solve this issue?
What things I need to consider for SAP NW BI 7.0 u2013 SAP BPC 7.5 NW (SP06, 07, 08) Implementation?
Your help is greatly appreciated.
Regards,
QadeerHi,
New SP was released in February, and now most of the new bugs should been caught ,This has a Central Note. For SP06 it's Note 1527325 - Planning and Consolidation 7.5 SP06 NetWeaver Central Note to fix any issues. Most of the improvements in SP06 were related to performance, especially when logging on from the BPC clients.There you should be able to find a big list of fixes/improvements and Notes that describe those. Some of the Notes even have test description how to reproduce that issue in the old version.
hope this will help you

APPEND IT_MATNR.
CLEAR IT_MATNR.
ENDLOOP.
I would sort IT_MARA by matnr then select for all entries into new table IT_matnr and only read when you are actuallygoing to use it for your final table.
This however will not make much difference to your problem. I suggest you put more of the code into subroutines and look at the se30 output as tyo which subroutines are actually taking most of the time. Please post the results and the subroutines which take the longest. -
Performance issue showing read by other session Event
Hi All,
we are having a severe performance issue in my database when we are running batch jobs.
This was a new database(11.2.0.2) and we are testing the performance by running some batch jobs. These batch jobs included some inserts and updates.
I am seeing read by other session in top 5 timed events and cache buffers chains in Latch Miss Sources section.
Please help me to solve this out.

Performance Issue in Oracle EBS
Hi Group,
I am working in a performance issue at customer site, let me explain the behaviour.
There is one node for the database and other for the application.
Application server is running all the services.
EBS version is 12.1.3 and database version is: 11.1.0.7 with AIX both servers..
Customer has added memory to both servers (database and application) initially they had 32 Gbytes, now they have 128 Gbytes.
Today, I have increased memory parameters for the database and also I have increased JVM's proceesses from 1 to 2 for Forms and OAcore, both JVM's are 1024M.
The behaviour is when users are navigating inside of the form, and they push the down button quickly the form gets thinking (reloading and waiting 1 or 2 minutes to response), it is no particular for a specific form, it is just happening in several forms.
Gathering statistics job is scheduled every weekend, I am not sure what can be the problem, I have collected a trace of the form and uploaded it to Oracle Support with no success or advice.
I have just send a ping command and the reponse time between servers is below to 5 ms.
I have several activities in mind like:
- OATM conversion.
- ASM implementation.
- Upgrade to 11.2.0.4.
Has anybody had this behaviour?, any advice about this problem will be really appreciated.
Thanks in advance.
Kind regards,
Francisco Mtz.Hi Bashar, thank you very much for your quick response.
If both servers are on the same network then the ping should not exceed 2 ms.
If I remember, I did a ping last Wednesday, and there were some peaks over 5 ms.
Have you checked the network performance between the clients and the application server?
Also, I did a ping from the PC to the application and database, and it was responding in less than 1 ms.
What is the status of the CPU usage on both servers?
There aren't overhead in the CPU side, I tested it (scrolling getting frozen) with no users in the application.
Did this happen after you performed the hardware upgrade?
Yes, it happened after changing some memory parameters in the JVM and the database.
Oracle has suggested to apply the latest Forms patches according to this Note: Doc ID 437878.1
Thanks in advance.
Kind regards,
Francisco Mtz. -
Performance issue with Adobe forms
Dear SAP Experts,
We have the following issue/requirement from our client. The client is on SAP ECC 6.0 - production environment.
The client is highlighting performance issue while accessing the adobe forms for HR and FI business process ( both static and interactive ).
Examples are
FI – Invoice Approvals
HR – Job Salary Change
The client is asking us to provide best practices surrounding:
1. How to improve the performance of the adobe forms while accessing in SAP.
2. Is there any other technology which we can use in SAP to replace the adobe forms which has better performance factor.
3. Are there solutions such as webdynpro floor plan manager, UI Fiori which can be alternately used?
Regards,
SakthiHello Priya,
Adobe forms are easy to develop and much more comfortable than SAP Scripts and Smartforms. Initially they are a bit difficult but once you have your hands on, they are the most simplest things in ABAP.
Performance in Adobe forms is a mix of both fine tuning the Layout as well as back end coding.
Performance in Adobe forms cannot be done overnight. A lot of care has to be taken during the initial stage of development.
As far as my experience is concerned, please consider the below points while developing SAP Adobe forms.
1) Avoid Scripting (Javascript/Formcalc) as much as possible inside the form. It drastically reduces the performance and makes the form to execute slower. If you still want to use scripting(which cannot be avoided for some requirements), use Formcalc since it is comparatively faster than JavaScript.
2) Try to avoid the coding inside the Form Interface. You can always handle the maximum coding in the Driver program and pass it to the form.
3) Use Form Caching.
For forms that have fixed layout, its a good way to increase the performance of form rendering. In the layout, go to Form Properties. Then Click on Defaults tab and select Allow Form Rendering To Be Cached On Server. Then Click OK.
For forms that have flowable or dynamic layout, render the forms on the client side because it improves performance.
Last but not the least, please go through the below post by Otto Gold which is worth a read at least once.

EP6 sp12 Performance Issue, Need help to improve performance
We have a Portal development environment with EP6.0 sp12.
What we are experiencing is performance issue, It's not extremely slow, but slow compared to normal ( compared to our prod box). For example, after putting the username and password and clicking the <Log on> Button it's taking more than 10 secs for the first home page to appear. Also currently we have hooked the Portal with 3 xAPPS system and one BW system. The time taken for a BW query to appear ( with selection screen) is also more than 10 secs. However access to one other xAPPS is comparatively faster.
Do we have a simple to use guide( Not a very elaborate one) with step by step guidance to immediately improve the performance of the Portal.
Simple guide, easy to implement, with immediate effect is what we are looking for in the short term
Thanks
ArunabhaHi Eric,
I have searched but didn't find the Portal Tuning and Optimization Guide as you have suggested, Can you help to find this.
Subrato,
This is good and I would obviously read through this, The issue here is this is only for Network.
But do you know any other guide, which as very basic ( may be 10 steps) and show step by step the process, it would be very helpful. I already have some information from the thread Portal Performance - page loads slow, client cache reset/cleared too often
But really looking for answer ( steps to do it quickly and effectively) instead of list of various guides.
It would be very helpful if you or anybody( who has actually done some performance tuning) can send a basic list of steps that I can do immediately, instead of reading through these large guides.
I know I am looking for a shortcut, but this is the need of the hour.
Thanks

Performance Issue-;How to restrict the total output of the report.
Hi Experts
I need your advise to resolve one performance issue in my BI Publisher report.
My report query is extracting more than 80000 records at once. To load these records into the report template it is taking all most 14 to 15 hours. Unfortunately i cannot change my logic to put some more filter to restrict the query output, as this is the requirement from the client.
Is there any way i can restrict my report so that it will extract the first 1000 record and on the event of pressing next it will extract the next 1000 record and so on from the point when it left in last time.
Kindly let me know if you have any solution for this.
Thanks in advance.

Performance issue when using select count on large tables
Hello Experts,
I have a requirement where i need to get count of data from a database table.Later on i need to display the count in ALV format.
As per my requirement, I have to use this select count inside a nested loops.
Below is the count snippet:
LOOP at systems assigning <fs_sc_systems>.
LOOP at date assigning <fs_sc_date>.
SELECT COUNT( DISTINCT crmd_orderadm_i~header )
FROM crmd_orderadm_i
INNER JOIN bbp_pdigp
ON crmd_orderadm_iclient EQ bbp_pdigpclient "MANDT is referred as client
AND crmd_orderadm_iguid EQ bbp_pdigpguid
INTO w_sc_count
WHERE crmd_orderadm_i~created_at BETWEEN <fs_sc_date>-start_timestamp
AND <fs_sc_date>-end_timestamp
AND bbp_pdigp~zz_scsys EQ <fs_sc_systems>-sys_name.
endloop.
endloop.
In the above code snippet,
<fs_sc_systems>-sys_name is having the system name,
<fs_sc_date>-start_timestamp is having the start date of month
and <fs_sc_date>-end_timestamp is the end date of month.
Also the data in tables crmd_orderadm_i and bbp_pdigp is very large and it increases every day.
Now,the above select query is taking a lot of time to give the count due to which i am facing performance issues.
Can any one pls help me out to optimize this code.
Thanks,
SumanHi Choudhary Suman ,
Try this:
SELECT crmd_orderadm_i~header
INTO it_header " interna table
FROM crmd_orderadm_i
INNER JOIN bbp_pdigp
ON crmd_orderadm_iclient EQ bbp_pdigpclient
AND crmd_orderadm_iguid EQ bbp_pdigpguid
FOR ALL ENTRIES IN date
WHERE crmd_orderadm_i~created_at BETWEEN date-start_timestamp
AND date-end_timestamp
AND bbp_pdigp~zz_scsys EQ date-sys_name.
SORT it_header BY header.
DELETE ADJACENT DUPLICATES FROM it_header
COMPARING header.
describe table it_header lines v_lines.
Hope this information is help to you.
