Runtime Performance

I have an application developed in JBuilder which utilises swing components in MDI forms.
How do I go about tuning it to make it faster ?
The database is MS Access via ODBC.
It takes approx 3 seconds to retrieve a form with a combo box and a table with 130 records !
This timing is on a 1Ghz Pentium III with 128Mb of RAM.
Any help would be much appreciated.

Find out what parts of your program are slow and speed them up. There are profiling tools that help you do that. In addition, since you are using a database, check whether you have indexes that support the selections you are making.

Compiling with debug and runtime performance degradation

Just a quick question: Does including debug information in class files degrade runtime performance in any way?
Thanks!

Quick answer: it depends on what your application does.
Mostly, it shouldn't matter but you should always profile and time your
application to find the truth.

Runtime performance with the debug flag enabled?

Does anyone know when I enable the debug flag, does it impact the runtime performance of my application? I assume when I use the "-g" option, only line number and source file information is generated. Any feedback appreciated.... thanks!

Since the only way to performance tune an application is with an automated preformance tool, I presume you have already done that and so are just trying to squeak that last bit of performance out of the app.
So just fire up the tool and see which one is faster.

Mapping Techniques determines Runtime Performance

What mapping technique offers the best performance at runtime (i.e. graphical, ABAP, Java, XSLT)? I have the ability to use anyone of these techniques, but I want to ensure I am using the one that offers the best performance at runtime, not the quickest/easiest to implement at design time.

Hi..
imo mapping performance does only partially depend on technique used, another important influence is the developer himself. You can develop highly performant graphical mappings, java mappings and also XSLT mappings but you have to focus on performance, know the concepts and maybe have someone else look at the mapping after it is finished I'm not sure about ABAP mapping, but i would say graphical and custom java have the same performance. XSLT is indeed slower, but there are some problems which can not be solved in graphical mapping (e.g. recursion) which can be solved rather easily in XSLT. Also SAP uses XSLT extensively in their standard content (e.g. MDM 3.0) where we have not encountered serious performance problems so far.

Crystal Reports XI Runtime Performance

I have Crystal Reports XI Developer Edition Installed. The reports I develop are deployed with a VB6 application using the Crystal Reports XI Merge Modules. On some of the reports we are seeing severe performance degradation if they are run from a machine with only the runtime installed. For example, if I run on of the reports (through the VB6 app) on my machine (with CR XI Developer Edition) installed I get the report displyed in 2 - 3 seconds. Running the same report on a different machine with only the CR XI runtime installed, and against the same database and database server, i.e. identical data set, the report will take 25 - 30 seconds. Any ideas where to start looking to trace the cause of this performance degradation?
Thanks in advance
Ian

Hi Ian,
Firstly you should download Cr XI R2 and all of it's service packs to bring you up to the latest version and it's a free download.
Secondly since you are using VB6 I assume you are using RDC report engine?
25 - 30 second delay doesn't sound obvious. Most times there is a delay of a minute or so due to the database the reports were designed against is no longer available, the delay is the connection time-out.
I would open those reports and in the Report Options menu check off Verify on first refresh, and Verify stored procedures. Also open up regedit and go to this location:
HKEY_CURRENT_USER\Software\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions and change VerifyWhenDBDriverUpgraded = to No.
Also change DoAutoSmartLinking = No on both the runtime and your dev PC. It can delay the opening while CR tries to link all tables and fields in the report.
I would then compare runtime files using various tools, Modules is available for download on our site, and compare all the runtime, not jsut CR. It may be a different version of your DB client or dependencies.
Next option is to add logging in your application that logs time to open the report, set DB logon info etc. to see which step is actually causing the delay.
Thank you
Don

How to improve performance of Oracle Forms Server ?

Recently we converted our Application which was Developed in Forms 5.0 and Reports 3.0 into Forms6i to host that on to Web. We also loaded ORACLE 9iAS (on Windows NT 4 with service pack 3) from "Enterprise Edition" option by selecting Oracle Database Cache, Forms Server and Reports Server, HTTP Server(on port 80),Oracle Web Cache. Everything loaded succesfully including Caches.
Forms server is working perfectly and we were able to run our Application in Browser, but performance is the issue. We thought the caches will improve the performance, but it seems they are not at all working. When we run a report or form the Database cache is not giving any statistics whether a particular Query is a Hit or Miss though the cache is running. We got a doubt and searched in FAQ's and we found the following questions.
Oracle9iAS Web Cache Frequently Asked
Questions February 2001
Does Oracle9iAS Web Cache work with applications that use Oracle9iAS Forms?
Not in the 1.x release of Oracle9iAS. Integration between Oracle9iAS Web Cache and Oracle9iAS Forms will be addressed at a future date.
Oracle9iAS Database Cache
Does the Cache work with Oracle Forms and Portal in Oracle9i AS?
Since Oracle Forms and Portal utilize read/write PL/SQL stored procedures, these components cannot take advantage of the Cache. This support is being considered for a future version.
After coming to know that Caches doesnot boost the performance of Oracle Forms and reports. We have the following queries.
1) Clarify whether the above are True.
2) Apart from DB and Web Cache is there any other way where in we can improve the performance of Oracle Forms and Reports in Forms Server including the start up time.
3) What is the ideal configuration required for each tier (iAS Server,Database Server and Client) to host Forms on to Web considering our application as Medium scale.
(Presently our configuration are,
Application Server Configuration : Windows NT 4 with service pack 3,256 MB RAM,1 GB Virtual memory and 4GB free space and almost the same configuration is being used for
Database Configuration.
Client Configuration : Windows 98 with 64MB RAM).
4) Is there any way to track the performance and know the problem areas like TRACE.
Gopi Kumar
null

A couple of questions for you:
1) What version of IAS are you using?
2) What's the version of Forms&Reports and
3) What version of patch are you using if any
for forms&Reports?
4) What applications are you running on the
machine where Forms&Reports is installed?
(I mean non-Oracle applications?)
The problem could be that, the base addresses
of the DLL's in Forms&Reports could be having base address conflicts with some other application's DLL's.
Forms and Reports needs to be fully rebased to achieve full performance on NT. Before release of Forms and Reports, Oracle rebases all DLLs. Rebasing assigns unique base addresses to all of the DLL's in use by an executable. A properly based DLL will load at its preferred base address, greatly improving the efficiency of memory utilization and the runtime performance of the executable.
Multiple utilities are available on NT to verify proper rebasing of DLLs. HandleEx v4.0 is one such freeware from Sysinternals and is available at www.sysinternals.com. Some others are "depends.exe" that's part of the MS Visual Studio or msinfo32.exe that comes with Office 2000 on NT.
If after running any of these utilities you discover that the DLL's ar not properly rebased, you need to contact Oracle worldwide support.
If you find that rebasing is not the problem, then please post your feedback again. Hope this helps.

8/20/2014 - Beta - AIR 15.0.0.233 Runtime and SDK

Adobe AIR Beta Channel Update
This beta release provides access to the latest AIR runtime and SDK (with compiler) for Windows, Mac OS, iOS and Android. You can download the AIR beta here: Download Adobe AIR 15 Beta - Adobe Labs
Below are some of the key features and benefits of AIR 15. Please see our release notes for full details.
New Features:
Stage3D “Standard” profile support for iOS and Android
In the Flash Runtime 14 release we introduced the Stage3D “Standard” profile which provided many advanced 3D features. At that time, the “Standard” profile was only available on desktop platforms. In the AIR 15 release we are extending this coverage to mobile platforms. If a device supports OpenGL ES3, it can successfully request the “Standard” profile and use the same advanced features as the desktop platform.
Relaxing Stage3D Render Target Clear
In previous versions of Stage3D, after switching the render texture through Context3D::setRenderToTexture, you were required to clear it before drawing. In this release, we're removing this limitation and optimizing the use of render textures. This change will allow you to further optimize and reuse depth and stencil buffers between different render textures.
StageText.drawViewPortToBitmapData now supports Retina displays
Currently, AIR will allow a bitmap with the same width/height of the StageText object to be passed into drawViewPortToBitmapData. While fine for standard resolution displays, this is not sufficient for Apple's Retina HiDPI displays. Based on customer feedback, we've altered the drawViewPortToBitmapData method to accept a doubled size BitmapData with StageText's view port on a Mac Retina display, and then draw a HiDPI image from the view port.
Improved Packaging Engine is now default - iOS
Starting AIR 15, new improved IPA packaging engine is now the default packaging mode when packaging for AOT targets ipa-app-store, ipa-test, ipa-ad-hoc and ipa-debug. If you encounter any packaging or runtime issues, please report at http://bugbase.adobe.com. To use older packaging mode, use "-useLegacyAOT yes" in the ADT command, before the signing options. To learn more about the feature, please follow http://www.adobe.com/devnet/air/articles/ios-packaging-compiled-mode.html
AIR Gamepad Enhancements
AIR Gamepad feature enables the app developers to provide a second screen on Android mobile devices for the Flash based browser games. AIR Gamepad API enables Flash based browser apps to connect to a paired Android device running the AIR Runtime app and therefore allowing the Android devices to be used as game controllers or second-screen interfaces. Following enhancements are available starting AIR 15.
Multiplayer Support
Gyroscope Events
Magnetometer Events
Applying skin as AIR gamepad screen
To learn more about the feature and usage guidelines, please follow www.adobe.com/devnet/air/articles/android-air-devices-as-gamepads.html
AIR Cross Promotion
Adobe AIR 15 now supports cross promotion of AIR games for mobile devices. Cross promotions can be effective in saving some amount of advertising cost. With the right partnership, you gain access to a wider customer base with a demographic similar to that of your application. This cross promotion is free and works on a credit system. All you need is to earn enough credit points by promoting other AIR games to begin your own promotion campaign. The AIR SDK offers the new AdViewer API for promotion campaigns as a SWC, it provides functions to load and show in-game advertisements. You earn credit points for promoting AIR games by other developers based on ad impressions and clicks. To learn more about the feature and usage guidelines, please follow www.adobe.com/devnet/air/articles/cross-promotion-of-air-games-mobile.html

You can find instructions for getting started with this release here: AIR Labs Page

I've settled on the following workaround, which fixes the problem consistently, albeit with a slight flicker sometimes:
Check if you're on Android;
Add an ENTER_FRAME listener to the stage in the activation handler (called when returning to the app from an overlay displayed by a native extension);
Use a ticker to have 2 frames delay between the quality switch, anything quicker than that resulted in inconsistent or non-functional behavior for our app;
Switch from StageQuality.LOW to StageQuality.HIGH and back again. Going to MEDIUM and back did *not* result in a fix.
In my case, the code for the switch itself looks like this:
private function OnActivate(event:Event):void
     if (Settings.IS_ANDROID)
          _Ticker = 0;
          stage.addEventListener(Event.ENTER_FRAME, OnEnterFrameFixGPUContextLoss);
private function OnEnterFrameFixGPUContextLoss(event:Event):void
     _Ticker ++;
     if (stage.quality.toLowerCase() == StageQuality.LOW) // stage.quality returns string in capitals
          stage.quality = StageQuality.HIGH;
     else
          if (_Ticker > 2)
               stage.quality = StageQuality.LOW;
               stage.removeEventListener(Event.ENTER_FRAME, OnEnterFrameFixGPUContextLoss);

URGENT------MB5B : PERFORMANCE PROBLEM

Hi,
We are getting the time out error while running the transaction MB5B. We have posted the same to SAP global support for further analysis, and SAP revrted with note 1005901 to review.
The note consists of creating the Z table and some Z programs to execute the MB5B without time out error, and SAP has not provided what type logic has to be written and how we can be addressed this.
Could any one suggest us how can we proceed further.
Note as been attached for reference.
Note 1005901 - MB5B: Performance problems
Note Language: English Version: 3 Validity: Valid from 05.12.2006
Summary
Symptom
o The user starts transaction MB5B, or the respective report
RM07MLBD, for a very large number of materials or for all materials
in a plant.
o The transaction terminates with the ABAP runtime error
DBIF_RSQL_INVALID_RSQL.
o The transaction runtime is very long and it terminates with the
ABAP runtime error TIME_OUT.
o During the runtime of transaction MB5B, goods movements are posted
in parallel:
- The results of transaction MB5B are incorrect.
- Each run of transaction MB5B returns different results for the
same combination of "material + plant".
More Terms
MB5B, RM07MLBD, runtime, performance, short dump
Cause and Prerequisites
The DBIF_RSQL_INVALID_RSQL runtime error may occur if you enter too many
individual material numbers in the selection screen for the database
selection.
The runtime is long because of the way report RM07MLBD works. It reads the
stocks and values from the material masters first, then the MM documents
and, in "Valuated Stock" mode, it then reads the respective FI documents.
If there are many MM and FI documents in the system, the runtimes can be
very long.
If goods movements are posted during the runtime of transaction MB5B for
materials that should also be processed by transaction MB5B, transaction
MB5B may return incorrect results.
Example: Transaction MB5B should process 100 materials with 10,000 MM
documents each. The system takes approximately 1 second to read the
material master data and it takes approximately 1 hour to read the MM and
FI documents. A goods movement for a material to be processed is posted
approximately 10 minutes after you start transaction MB5B. The stock for
this material before this posting has already been determined. The new MM
document is also read, however. The stock read before the posting is used
as the basis for calculating the stocks for the start and end date.
If you execute transaction MB5B during a time when no goods movements are
posted, these incorrect results do not occur.
Solution
The SAP standard release does not include a solution that allows you to
process mass data using transaction MB5B. The requirements for transaction
MB5B are very customer-specific. To allow for these customer-specific
requirements, we provide the following proposed implementation:
Implementation proposal:
o You should call transaction MB5B for only one "material + plant"
combination at a time.
o The list outputs for each of these runs are collected and at the
end of the processing they are prepared for a large list output.
You need three reports and one database table for this function. You can
store the lists in the INDX cluster table.
o Define work database table ZZ_MB5B with the following fields:
- Material number
- Plant
- Valuation area
- Key field for INDX cluster table
o The size category of the table should be based on the number of
entries in material valuation table MBEW.
Report ZZ_MB5B_PREPARE
In the first step, this report deletes all existing entries from the
ZZ_MB5B work table and the INDX cluster table from the last mass data
processing run of transaction MB5B.
o The ZZ_MB5B work table is filled in accordance with the selected
mode of transaction MB5B:
- Stock type mode = Valuated stock
- Include one entry in work table ZZ_MB5B for every "material +
valuation area" combination from table MBEW.
o Other modes:
- Include one entry in work table ZZ_MB5B for every "material +
plant" combination from table MARC
Furthermore, the new entries in work table ZZ_MB5B are assigned a unique
22-character string that later serves as a key term for cluster table INDX.
Report ZZ_MB5B_MONITOR
This report reads the entries sequentially in work table ZZ_MB5B. Depending
on the mode of transaction MB5B, a lock is executed as follows:
o Stock type mode = Valuated stock
For every "material + valuation area" combination, the system
determines all "material + plant" combinations. All determined
"material + plant" combinations are locked.
o Other modes:
- Every "material + plant" combination is locked.
- The entries from the ZZ_MB5B work table can be processed as
follows only if they have been locked successfully.
- Start report RM07MLBD for the current "Material + plant"
combination, or "material + valuation area" combination,
depending on the required mode.
- The list created is stored with the generated key term in the
INDX cluster table.
- The current entry is deleted from the ZZ_MB5B work table.
- Database updates are executed with COMMIT WORK AND WAIT.
- The lock is released.
- The system reads the next entry in the ZZ_MB5B work table.
Application
- The lock ensures that no goods movements can be posted during
the runtime of the RM07MLBD report for the "material + Plant"
combination to be processed.
- You can start several instances of this report at the same
time. This method ensures that all "material + plant"
combinations can be processed at the same time.
- The system takes just a few seconds to process a "material +
Plant" combination so there is just minimum disruption to
production operation.
- This report is started until there are no more entries in the
ZZ_MB5B work table.
- If the report terminates or is interrupted, it can be started
again at any time.
Report ZZ_MB5B_PRINT
You can use this report when all combinations of "material + plant", or
"material + valuation area" from the ZZ_MB5B work table have been
processed. The report reads the saved lists from the INDX cluster table and
adds these individual lists to a complete list output.
Estimated implementation effort
An experienced ABAP programmer requires an estimated three to five days to
create the ZZ_MB5B work table and these three reports. You can find a
similar program as an example in Note 32236: MBMSSQUA.
If you need support during the implementation, contact your SAP consultant.

Optimizing built application performance in LV 2012 (and earlier)

There's a new help topic in the LabVIEW 2012 help called Optimizing Execution Speed for Built Applications. If you're interested in the runtime performance of your built applications (EXEs, DLLs, etc.), I'd recommend taking a look.
Most of the steps apply to earlier versions of LabVIEW as well - just ignore the steps that mention the "compiler optimization threshold".

If the application is running on a standalone computer with no access to the internet, then the aplication may be taking a really long time to load. This is because Windows is trying to check the applicaton's signature over the internet when there is no internet connection.
The solution to this problem is found here:

Extension Manager and performance

from the JDeveloper documentation:
Extensions are components that are optionally loaded when JDeveloper is launched. Many of JDeveloper's standard features are installed as extensions. Disabling unneeded components can improve launch time significantly.
question:
It improves launch time, but does it also improve JDeveloper overall performance?
tnx
-Jan

Yes, it can also improve the runtime performance a bit.

Fast_start_mttr_target performance

On 10.2.0.3 database fast_start_mttr_target is set to 300 and OPTIMAL_LOGFILE_SIZE from V$INSTANCE_RECOVERY shows 6762M after a morning of heavy database activity. My quesiton is this: Does the fast_start_mttr_target parameter have any performance impact on the database or is it primarily for calculating and suggesting optimal log size? Does increasing the fast_start_mttr_target affect log switching? If I increased the fast_start_mttr_target to 900 or 1800 would this help log performance (i.e. not switching too often)? I will increase log size as well, but does fast_start_mttr_target setting have performance implications?
Curt Swartzlander
[email protected]

Yes I found the answer in this documentation!!
To reduce the checkpoint frequency and optimize runtime performance, you can do the following:
Set the value of FAST_START_MTTR_TARGET to 3600. This enables Fast-Start checkpointing and the Fast-Start Fault Recovery feature, but minimizes its effect on runtime performance while avoiding the need for performance tuning of FAST_START_MTTR_TARGET.
Thank you and please reply to this threas so I can give you a "correct" star. I meant to do this to your reply but did something wrong.

Effect of Restricted Keyfigure & calculated keyfigure in query performance

Hi,
What is the effect of Restricted Keyfigure & calculated keyfigure in Query Performance?
Regards
Anil

As compared to formulas that are evaluated during query execution, calculated key figures are pre-calculated and their definitions are stored in the metadata repository for reuse in queries. The incorporation of business metrics and key performance indicators as calculated key figures, such as gross profit and return on investment (which are frequently used, widely understood, and rarely changed), improve query performance and ensure that calculated key figures are reported consistently by different users. Note that this approach improves query runtime performance but slows InfoCube or ODS object update time. As a rule of thumb, if multiple and frequently used queries use the same formula to compute calculated fields, use calculated key figures instead of formulas.
RKFs result in additional database processing and complexity in retrieving the query result and therefore should be avoided when possible.
other than performance, there might be other considerations to determine which one of the options should be used.
If the RKF's are query specific and not used anywhere in majority of other queries, I would go for structure selections. And from my personal exp, sometimes all the developers end up with so many RKF and CKF's that you get easily lost in the web and not to mention the duplication.
if the same structure is needed widely across most of the queries, that might be a good idea to have global structure to be available across the provider, which might considerable cut down the development time.

Structures Vs RKFs and CKFs In Query performance

Hi Gurus,
I am creating a GL query which will be returning with a couple of KFs and some calculations as well with different GL accounts and I wanted to know which one is going to be more beneficial for me either to create Restricted keyfigures and Calculated Keyfigures or to just use a structure for all the selections and formula calculations?
Which option will be better for query performance?
Thanks in advance

Long runtime of RBDMIDOC for IDoc ARTMAS

Hi,
   We are in IS Retail. We are using IDoc to capture article master creation & changes, and to reflect those details in retail stores. For this we have created custom Z message type & assigned it to a sap standard basic idoc type ARTMAS05. We have also activated the change pointer ARTMAS. There s no issue in IDoc generation. But when we run the program RBDMIDOC for Idoc generation, it is taking hours together for execution.
   I could not find any sap note for performance improvement, whereas for MATMAS there are performance notes 863744.
   Is there any solution for runtime / performance improvement for RBDMIDOC, for idoc type ARTMAS ?
regards,
Nagarajan.J

Hi,
I am also having the similar requirement but only problem is when i try to create idoc through BD21 system is creating idoc of message type ARTMAS although I have defined bespoke message type,
can you please tell me if in your case bespoke message type is being selected for creating idoc if yes then please let me know which config I may be missing.
Thanks in advance for your help.
Cheers

Ws-security runtime authentication subject

Hi,
When the ws-runtime performs the authentication based on the security token, does it attach the authenticated subject to the current thread?
In the server-side handler for a webservices on which ws-security is enabled via ws-policy, if I call
SubjectUtils.getUsername(weblogic.security.Security.getCurrentSubject()
I am not getting the username i passed in the token as the authenticated subject.
Can you please tell me which user does it attach to the current thread in webservices?

Thanks for reply.
Does that mean - there is NO WAY for X.509 certificate Authentication between OEG and OAM - regardless any OEG filter ?
