Correlations - Usage and performance

Hello forum users,
I would like to know until where I can go with BPM using correlation.
My need is to initiate a BPM with a first message and finish it at the arrival of a second one (different message) using a correlation Identifier. Such a standard case.
My question is : It is a problem if the second message is able to arrive many weeks after the first. and during this time many and many other instance of the same BPM will be initiate....
Must I care with performance issue ?
How ?
BPM steps in detail :
Flat file representing a customer sales order is received => Init BPM
Syncrhonous BAPI call on R/3. Response give sd document number => Activation of correlation
BPM send a first (technical) acknowledgement file to original sender.
Now a second acknowledgement file (more business one) must be send when all the items are ok (It may have been errors in automatic integration...). In order to be in this configuration, user actions may be required and this can take a long time (many days, week)
When user decide sd documents is full and ok, SAP R/3 send the second message that close the correlation and trigger the end of BPM (generating ack flat file N°2)
(I imagine the second message as an ORDRSP trigger by an output SAP Control)
Thanks for your advices.

hi,
To explain you the correlation in simple terms...take a simple example of BPM with a send step(async request) and receive step(async response). I am sending a PO request using the send step and waiting for a PO response using the recieve step. Assume that i have two instances of this BPM running i.e two PO request's going simultaneously. when i get the response back for these two requests , there will be two recieve steps waiting for the response since there are two instances of BPM running. the response need to be assigned the corresponding requests. This is where correlation comes into picture. I can use PO number as my correlation field. i.e I activate my correlation in the send step and use this correlation in receive step (this is configurable in BPM).
Example: PO number needs to be part both request and the response message structure.
BPM instance1:
send step -> activate correlation -> send message with PO Number1
Receive step -> use correlation -> receive response message with PO Number 1.
BPM instance1:
send step -> activate correlation -> send message with PO Number2
Receive step -> use correlation -> receive response message with PO Number 2.
There are many different scenario's whre you can use the correlation..this is one of them...The weblog shows another way of using correlation.
Also Refer SAP help...
Correlating Messages
Use
You use a correlation to assign messages that belong together to the same process instance. A correlation joins messages that have the same value for one or more XML elements. A correlation is therefore a loose coupling of messages: at design time, it enables you to define which message a receive step must wait for, without knowing the message ID.
For example, in a process, receivestep_1receives the message purchaseorder, while receivestep_2receives the message salesorder. Receivestep_1creates a correlation that defines that the corresponding sales order must have the same purchase order number. Receivestep_2uses this correlation. This means that an instance of the process processes a purchase order and the corresponding sales order, which has the same purchase order number.
If it satisfies the relevant correlations, a message can be processed in multiple processes. However, a message is only delivered once per process.

How can I optimize my hard disk drive usage and performance in Windows 8 or Windows 7?

QuestionHow can I optimize my hard disk drive usage and performance in Windows 8 or Windows 7?
AnswerThere are a few simple steps you can take to ensure your hard disk drive is used optimally.
Use Toshiba HDD Protection
Many Toshiba laptops come with a program called Toshiba HDD Protection pre-installed. This program helps to protect your hard disk drive from being damaged due to falls or impacts. By default, it should already be enabled. You might be tempted to lower the detection levels in this application, but doing so could cause your hard disk drive to be damaged. Remember that while the application can reduce the chance of damage, you should still avoid allowing the laptop to fall or suffer rapid impacts.
For more information on this utility, see the following article:
TOSHIBA HDD Protection
Optimize the drive
Windows 8 and Windows 7 optimize hard disk drives automatically through a process called defragmentation. Unless you've disabled this, you don't need to do anything. If you have disabled this and want to run the process, you can still do so.
In Windows 8, search for "Defrag" at the Windows Start screen and select "Defragment and optimize your drives."
In Windows 7, search for "Defrag" in the Start Menu's search field and select "Disk defragmenter."
You can use this tool to optimize your hard disk drives, allowing Windows to find needed files faster.
Remove items from startup
Some applications run automatically when Windows starts. This can add additional functionality, but it also decreases the performance of your computer. Sometimes you might want to disable certain programs from starting automatically.
In Windows 8, search for "Task Manager" at the Start screen. Select the "Startup" tab. Select an application you'd like to disable from starting automatically and then click the "Disable" button in the lower-right.
In Windows 7, type "msconfig" in the Start Menu's search field and press ENTER. Uncheck the boxes next to applications you'd like to disable from starting automatically.
You should be sure of the purpose of an application before disabling it from starting automatically. Some applications might be important. If in doubt, you might consider searching on the Web to discover more information about a program. Remember that if you find that you disabled something vital, you can always re-enable it.

In the Aurora "about" window it notes it automatically sends Mozilla info like usage and performance, etc. Does disabling telemetry etc in options disable this?

As the questions says, does disabling the telemetry options in the browser settings disable any information, usage, and performance sharing as it does in Firefox proper, in spite of the blurb in the Aurora "about" window?

hello Alxlight, the text in the about-dialog is static and should just inform users about the default configuration in the experimental aurora/nightly channels of firefox. when you decide to disable the various settings in ''options > advanced > data choices'' this data won't be submitted to mozilla, despite what the about-dialog says...

How to monitor CPU usage and performance on a Hyper-V server with several VM's

I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system.
I have set up three Virtual Machines, all running Windows 2008 32 bit.
Build server, running Team City
Staging server
SQL Server, running SQL Server 2005
I have some troubles with the setup in that the host monitor remains responsive at all times, even though the VM's are seemingly working at 100% cpu and are very sluggish and unresponsive. (I have asked a separate question about that.)
So the question here is: What is the best way to monitor how the physical CPU's are actually utilized? The reason I am asking is that I am being told that i cannot reliably use the task manager to monitor CPU usage in a VM.

First, you have to remember that in Hyper-V that the "host" is called a parent partition and it really just like a virtualized guest with special permissions and roles. Just like any other child/guest, when you open up Task Manager, you can not see the CPU
usage of the other children on the server.
Ben Armstrong has a good explanation of this here:http://blogs.msdn.com/virtual_pc_guy/archive/2008/02/28/hyper-v-virtual-machine-cpu-usage-and-task-manager.aspx
To summarize his post, you need to check three things to get an accurate picture of CPU utilization:
View the CPU usage on each guest - this is available through Hyper-V Manager or Performance Monitor.
CPU usage due to context switching - this is the perfmon counter called % Hypervisor Run Timeunder Hyper-V Hypervisor Virtual Processor
Child partition worker process - vmwp.exe running on the parent partition (1 per child). This handles Hyper-V operations like saving
state.

XI Design Issue- BPM Usage and Performance

Hi All
System A is sending mutiple messages to XI and every message has a node called TEVEN which has line Items. The TEVEN is repeated and based on EId value. The receiver has to be decided, that means a single message can have multiple same Eid which has to be colleted in one set of Message and XI will keep on receiving such messages for 30 minutes and after the same grouping from all messages and their payload being done a file will be created to different Receivers (in case of Eid 1 the receiver will be System A in case of Eid 2 the receiver will be System B)
How do I Achieve this in my BPM - the problem is to go through every message payload and then collect TEVEN header in one single message and keep on doing so for all messages received within 30 minutes and then using file adpater put those files on File Server (The receiving system desires to have only one file and will check every 30 minutes for the file)
Any thoughts on designing this scenarion in XI are welcome. And also regarding comments on designing a BPM to handle this and the performance related with that.

Hi,
If you have collect the messages till 30 mins and then create a file then i see you have to use BPM only.
You can use the correlation for different Eid, or you can use the option of Enhanced Receiver Determination.
The help for both is available on SDN.

Request mechanism to retrieve usage and performance statistics in BPC?

Hi BPC Gurus,
We have just completed rolling out BPC 5.1 and were interested in monitoring the health & user adoption (e.g. number of users logged in, how many times they logged in, what kind of reports they ran, how long the EVDRE query for those reports took etc).
I have scoured through all the available tables for the Appset & the audit database at the SQLServer level and could not find any table that holds information around this. The only information I found was around the logged in statistics for Administrators via table tblLoggedIn and the statistics of who keyed in data using Input templates via the audit tables.
Is there some roundabout way to get this information at least something to the tune of who logged in and when?
On the BW side, there is a rich set of information through the use of pre-delivered Statistics cube that provides myriad details which can be used to monitor the health and usage of the system. Are there plans to include this kind of statistical information in BPC 7.0?
Your help and guidance would be greatly appreciated.
Thanks,
Abhay Shanbhag

Yes, BPC 7.0 has a statistics mechanism.

Printing memory and performance optimization

Hello,
I am using JVM 1.3 for a big Java Application.
Print Preview consumes 1.5MB of JVM's memory and performance is slow.
Please give your valuable ways to reduce memory usage and performance improvement
will be appreciated.
/* print method in ScrollablePanel extends JPanel */

Good day,
As I tried, there are two ways of doing printPreview.
To handle this problem, add only one page at a time.
To browse through the page use Prev Page, Nexe Page buttons in the toolbar.
1) BufferedImage - occupies memory .
Class PagePreview extends JPanel
public void paint(Graphics g) {
g.setColor(getBackground());
g.fillRect(0, 0, getWidth(), getHeight());
g.drawImage(m_img, 0, 0, this);
paintBorder(g);
This gives better performance, but consumes memory.
2) getPageGraphics in the preview panel . This occupies less memory, but re-paint the graphics everytime when paint(Graphics g) is called.
Class PagePreview extends JPanel
public void paint(Graphics g)
g.setColor(Color.white);
RepaintManager currentManager = RepaintManager.currentManager(this);
currentManager.setDoubleBufferingEnabled(false);
Graphics2D g2 = scrollPanel.getPageGraphics();
currentManager.setDoubleBufferingEnabled(true);
g2.dispose();
This addresses memory problem, but performance is better.
Is there any additional info from you?
Good Luck,
Kind Regards,
Krish

Is there a documented correlation between high CPU/RAM usage and poor system performance?

I realize this subject is not black and white and has quite a bit of depth to it as high usage of either the CPU or RAM does not necessarily mean that a computer is running slowly.
However, is there any documentation, scientific research or academic journal that makes a correlation between poor system performance and the consumption of system resources.
It goes without saying that if you use all your RAM then there won't be any available for additional programs, but can this be substantiated with metrical data?

QFS filesystem "mm" device inode usage and recovery

I have questions regarding inode usage on a QFS filesystem. Our QFS filesystem “mm” devices are filling up rather quickly and we are trying to understand why. The SAMFS/QFS documentation doesn’t go into that much detail on explaining inode usage from a metadevice standpoint. Here is a small part of the output from “samcmd –m” command:
mm 1001 95% on 0 3.996G 206.875M [423680 inodes]
mm 1001 100% on 0 3.996G 0 [0 inodes]
The first question I have: When do the “mm” device inodes get created, or better yet get USED? I understand files and directories are assigned inodes, but we have observed that just creating files and directories doesn’t USE the “mm” inodes. I have created multiple files and directories in our QFS filesystem, ran the “samcmd –m” command, and the output of free inodes is still the same.
Next question: How does the QFS filesystem recover “mm” device inodes? Just removing a couple files doesn’t increase the number of inodes available, but in one instance I deleted 60000 directories and suddenly over 400000 inodes are freed up. Is there a correlation between inodes freed up and the files? I would figure there would be one inode for each, but there seems to be more. I understand samfsck would recover inodes as well.
Basically my goal is to understand when the inodes are created/used up and how they are recovered. I understand that I may need to add additional “mm” devices, using the samgrowfs command, but don’t want to do that quite yet. Any help understanding QFS "mm" device inode usage and recovery is appreciated.

The PC was indeed turned off between the two checks.
However the first check was not performed right before the shutdown, but few hours before it.
:idea:
(...) varying from browser cache data increase to a cronjob like updatedb, or even you installing or downloading something.
When I've read these words I have started to "scroll" back in my memory buffer and eventually I've remembered that the only thing I did as superuser was to download some Firefox extensions which (surprise or not...) summed up to ~12M.
So we have the answer for this one too thanks to your hints
PS: That's exactly the reason why I've made a small / partition - to keep a close eye on it's usage and to ring some allarms when needed.
Again, thank you.

Data usage and battery drain has skyrocketed with iOS 8.1.2 (maybe earlier)

3 weeks ago my wife got a text message on her iPhone 5 from AT&T that she had used 90% of her data for the month. 30 seconds later, she got another one saying that she had used 100%. Granted, her data plan is small, 200 MB. But, for the last two years she has used as little as 17 MB in a month and her largest prior to this latest month was 49 mb. This month she got to 380 mb before we were able to shut off her cell data. Otherwise, a second chunk of 200 MB and another $15 would have been added to the month.
We had noticed that her battery had been draining rather rapidly in standby mode with no background apps running when she didn't have access to WiFi. We have now correlated the two results, High Cell data usage, Quick battery drain and very warm phone. In case anyone is wondering about her iPhone 5 being one in the recall, it is. I took it in and had it tested. Apple says the battery is fine. It does hold a charge well. When all network communications are shut down on her phone and it is in standby mode, there is no noticeable loss of charge in 24 hours (our longest test).
Since I have a grandfathered Unlimited Data Plan with AT&T, I have been doing some testing on my iPhone 5s. Sure enough, I've seen similar results. With nearly everything turned off except Cell Data, I've seen 483 MB used in 24 hours. Of that total, 479 MB was used for Documents & Sync. I even have everything turned off in my iCloud account, Location services are turned off, no push notifications etc...
The best I can figure, this has been a problem since we installed 8.1.2 and yesterday I installed 8.1.3 resulting in no positive effect on this issue.
At this rate of data usage and no access to WiFi, my wife would have to have a 15 Gb data plan to keep from exceeding her limit. I don't think AT&T even offers one that big anymore. I might have to switch to Sprint or T-Mobile if this doesn't get resolved.
Any ideas would be greatly appreciated. Thanks in advance for your shared insights.

Hey this is Brian, bjmcmurry, under a different user ID. If I logged in as bmcmurry, original post, I was just getting a server error and couldn't get to this discussion nor post a comment anywhere.
Anyway, let me be as brief as I can. After an extensive analysis of replicating the problem on another phone to eliminate it being a hardware specific issue and that the test phone has an unlimited data plan, I was able to stop the excessive data usage and consequential battery drain. I believe I have a reasonable explanation of the problem, an iOS logic bug.
I had everything under my control clamped down on the test phone to minimize data usage. Also, I was forcing all data usage to use the cell towers. I determined that I was burning at least 11 to 13 Mb per hour doing nothing important. I literally had everything turned off except 'Settings' was allowed to use Cell data providing a avenue to log into the Apple ID.
The two phones had 2 things in common, they were using the same Apple ID and the same version of the OS. One was a iPhone 5 and the other was a 5s.
Here is a synopsis of my experience via my written evaluation of the Apple support system (Apple Rep name's have been removed):
After a couple of hours on the phone with an Apple Care Senior support Analyst, it was suggested that I go to the Apple Store to 1) get my battery replace in the iPhone 5 since it qualified for the replacement program and 2) see if the Genius could provide me with any insight in the data usage issue and battery drain.
I'm certainly glad I had multiple reasons to visit the closest Apple store, a 45 min drive. I got the battery replaced, thanks for that.
Regarding the important issue to me that brought me to the Genius Bar, excessive Cell data usage, I thought the Genius did a wonderful job listening and documenting the problem we were experiencing. Unfortunately, educating us on the use of the product or replacing our phone was not going to solve the problem. He eventually figured it out, this was not a user error or broken hardware. We surmised that the reason I was sent to him was to verify and document that there was a problem. I clearly had a problem. After writing copious notes on the issue, The Genius smartly referred me back the the AppleCare Senior Advisor. So, back to AppleCare Senior Analyst I went. She, knowing this was not a simple problem to solve i.e. beyond her level of expertise, got an Apple Software engineer involved.
My primary frustration is that this should have been escalated to software engineering right away. My trip to see the Genius was, I believe, a waste of time for both me and Apple regarding this issue. Diagnosis of this type of problem is well beyond the Genius’ knowledge and job. The Genius did a very good job doing what he could within the scope of his job. He just couldn’t solve this problem and had no one within Apple to which he had access for help.
However, that initial consult with the engineer was a bit feeble. Not only could I not talk to him/her directly, his/her focus was still working with the ‘Black Box' approach. Having Analyst ask me to do stuff like restore the Phone was more like trying to find a 'work around' than 'identifying the real problem.' Maybe restoring the phone was going to fix some corrupted data on the phone sidesteping the real problem, the handling of this condition. The engineer did listen to the fact that I had restored the test phone, the 5s, and only added the use of my Apple ID. Duh, been there!!!
Having been an previous owner of a software development company that I started in 1980 and retired in 2001, I can tell you that using the 'Black Box' method of debugging is extremely inefficient. Instead, having access to an ‘Activity Manager’ type app to identify in real time what process was blowing up the data flow would have saved me a lost afternoon at the Apple store and hours on the phone with tech support.
Ironically, I may have stumbled onto a "work around" solution short of turning off Cell Data that stopped the excessive Cell Data usage and consequential battery drain. Just prior to leaving the Apple Store, I used one of their Macs to log in my Apple ID on the id.apple.com website to ‘Manage my Apple ID’, I was forced to upgrade the security level of my password. Afterward, my cell data usage seemed to drop dramatically.
I told the AppleCare Senior Analyst that I may have stumbled onto a workaround and I suggested that I give it a couple of days of monitoring. We'd talk then and I would have results to report. She agreed.
Sure enough, my Document & Sync usage was back to normal, about 1/2 Mb per day. Am I happy that the excessive Cell Data usage has stopped? You bet! But, there was no intuitive reason that an end user would know to log in on the ID website to unknowingly solve this problem. As I use to say to my employees, that is not the ‘Macintosh Way.’ And, rebooting the the 'Microsoft Way.'
When I reported my findings to the Analyst, we both concluded that data usage was back to normal. She did report to me that the engineer did provide a laundry list of suggested activities to help solve the problem. Remarkably, they were everything that I had already done and were pretty much what the Analyst and the Genius tried to do. All reasonable tasks. But clearly, the engineer hadn't even ready the notes on the case before responding. And, none of the things suggested would have uncovered the real problem, likely a logic bug in iOS.
My advice now is to have the software engineering team rule out that there was an unresolvable state that a background process was fiercely trying to handle. The iOS does not seem to know how to intervene and prompt the user with a requirement to upgrade their password. If this does end up being the case, I would call it a logic bug, a perpetual exception that is not being handled properly.
Anyway, I hope this helps you.

Important!! Improve the life and performance of the battery.

Reduce the operating temperature and increase battery life
The battery in your notebook PC is designed to provide the necessary amount of energy for the processor while maintaining HP high safety standards. As a result, the battery may not charge or may stop providing power to the notebook when the battery temperature exceeds the specified, design safety level.
If the battery life appears shorter than normal, the battery stops charging before it is 99%-100% full and the battery appears warmer than usual, the battery has most likely reached its designed "no charge" safety state. The battery will no longer charge until the temperature condition is corrected.
Try one of the following methods to correct the battery temperature:
When charging the battery, do not use applications that require large amounts of system resources such as graphic or memory intensive applications, heavy and extended hard drive usage.
Turn off your notebook and remove the battery to allow it to return to a safe operating temperature.
Make sure the notebook PC is operating on a hard surface. Using the Notebook PC on a bed or sofa may block the vents causing the notebook PC to heat up and shut down.
By taking these steps, the battery will return to its normal operating temperature range and continue to charge and discharge as designed.
Calibrating the battery while PC not in use
Recalibrating the battery requires a cycle of a complete charge and a complete discharge. To recalibrate the battery while using the PC is not is use complete the following steps.
The recalibration may take 1-5 hours depending on the age of the battery and the configuration of the notebook PC you own. The PC should not be used while you perform the following steps. Completing all the following steps will also calibrate the battery so that the power meter readings are accurate.
Shut down the notebook PC
Connect the AC Adapter to the notebook PC and to an electrical socket.
Charge the Notebook PC until the Battery Charge light is Green. This indicates the battery is completely charged.
Press and release the Power Button to start the computer.
Press the F8 key several times when the HP Logo displays.
When the Windows Advanced Startup Menu displays, select the Startup in Safe Mode option.
Remove the AC power adapter from the notebook PC.
Allow the battery to discharge completely until the notebook PC turns off.
The battery is now calibrated and the battery level reading on the power meter is now accurate.
If you are not using the notebook regularly then please unplug the AC adapter and shut down the notebook. By following these practices will improve the life and performance of the battery. Here is a quick list of Do's and Don'ts for the care of your Li-On batteries:
Do's
When you receive a new Notebook or Tablet PC, leave the battery to fully charge overnight.
Condition a new battery by using it until it is fully discharged, and then re-charge it fully. Doing this once a month will help to accurately calibrate your battery.
Always ensure the battery is recharged as soon as possible after it becomes fully discharged. A battery will be permanently damaged if left for an extended length of time in a fully discharged state.
Remember that a Lithium-Ion battery will slowly deteriorate; a new battery will always perform better than one that is 6-months old.
Remember that the battery half-life is rated for a certain total number of charge/discharge cycles (see your User Manual or Quick Start Guide for the rating). For example, a battery that is rated for 3 hours and 500 charge/discharge cycles, will still be considered as within specification, even if it only lasts for 1 hour 45 minutes after 500 charge/discharge cycles.
Heat is the worst enemy of a battery. Allow plenty of air to circulate around the Notebook/Tablet PC, so that the battery is kept as cool as possible when charging and also when in use. If provided, use the integrated 'legs' under the Notebook to raise the notebook and improve air circulation.
Remove the battery if storing for several months (the battery should be at approximately 50% charge or higher).
If you use a NoteBus or if charging your Notebooks or Tablet PCs in a confined space, allow for adequate ventilation in order to keep the batteries as cool as possible.
Don'ts
Do Not - Expose the battery to excessive heat or cold (i.e. outside the range of 10-35 degrees Centigrade ambient).
Do Not - Store the battery in a fully charged state (store batteries with about 50% charge).
Do Not - Allow a nearly flat battery to be unused for more than a month or so. The battery will slowly discharge until it becomes fully discharged and this will permanently damage the battery cells.
Do Not - Charge your Notebook/Tablet PC inside a carry case - the battery may overheat.
Do Not - Charge your Notebook/Tablet PC when stacked on top of each other - the battery may overheat.
Remember: Your battery is slowly degrading all the time, even if it is not used. Keeping your battery as cool as possible will slow down this degradation considerably.

Hi,
There are four main tasks to use Azure Diagnostics:
Setup WAD
Configuring data collection
Instrumenting your code
Viewing data
The original Azure SDK 1.0 included functionality to collect diagnostics and store them in Azure storage collectively known as Azure Diagnostics (WAD). This software, built upon the Event Tracing for Windows (ETW) framework, fulfills two design requirements
introduced by Azure scale-out architecture:
Save diagnostic data that would be lost during a reimaging of the instance..
Provide a central repository for diagnostics from multiple instances.
After including Azure Diagnostics in the role (ServiceConfiguration.cscfg and ServiceDefinition.csdef), WAD collects diagnostic data from all the instances of that particular role. The diagnostic data can be used for debugging and troubleshooting, measuring
performance, monitoring resource usage, traffic analysis and capacity planning, and auditing. Transfers to Azure storage account for persistence can either be scheduled or on-demand.
To know more about Azure Diagnostics, please refer to the below article ( Section : Designing More Supportable Azure Services > Azure Diagnostics )

Memory and performance when copying a sorted table to a standard table

Hello,
As you all probably know, it's not possible to use a sorted table as a tables parameter of a function module, but sometimes you want to use a sorted table in your function module for performance reasons, and at the end of the function module, you just copy it to a standard table to return to the calling program.
The problem with this is that at that moment, the contents of the table is in memory twice, which could result in the well known STORAGE_PARAMETERS_WRONG_SET runtime exception.
I've been looking for ways to do this without using an excessive amount of memory and still being performant. I tried four methods, all have their advantages and disadvantages, so I was hoping someone here could help me come up with the best way to do this. Both memory and performance are an issue.
Requirements :
- Memory usage must be as low as possible
- Performance must be as high as possible
- Method must work on all SAP versions from 4.6c and up
So far I have tried 3 methods.
I included a test report to this message, the output of this on my dev system is :
Test report for memory usage of copying tables
table1[] = table2[]
Memory :    192,751 Kb
Runtime:    436,842
Loop using workarea (with delete from original table)
Memory :    196,797 Kb
Runtime: 1,312,839
Loop using field symbol (with delete from original table)
Memory :    196,766 Kb
Runtime: 1,295,009
The code of the program :
I had some problems pasting the code here, so it can be found at [http://pastebin.com/f5e2848b5|http://pastebin.com/f5e2848b5]
Thanks in advance for the help.

I've had another idea:
Create a RFC function like this (replace SOLI_TAB with your table types):
FUNCTION Z_COPY_TABLE .
*"*"Lokale Schnittstelle:
*" IMPORTING
*"     VALUE(IT_IN) TYPE SOLI_TAB
*" EXPORTING
*"     VALUE(ET_OUT) TYPE SOLI_TAB
et_out[] = it_in[].
ENDFUNCTION.
and then try something like this in your program:
DATA: gd_copy_done TYPE c LENGTH 1.
DATA: gt_one TYPE soli_tab.
DATA: gt_two TYPE soli_tab.
PERFORM move_tables.
FORM move_tables.
CLEAR gd_copy_done.
CALL FUNCTION 'Z_COPY_TABLE'
    STARTING NEW TASK 'ztest'
    PERFORMING copy_done ON END OF TASK
    EXPORTING
      it_in = gt_one[].
CLEAR gt_one[].
WAIT UNTIL gd_copy_done IS NOT INITIAL.
ENDFORM.
FORM copy_done USING ld_task TYPE clike.
RECEIVE RESULTS FROM FUNCTION 'Z_COPY_TABLE'
   IMPORTING
     et_out        = gt_two[].
gd_copy_done = 'X'.
ENDFORM.
Maybe this is a little bit faster than the Memory-Export?

How can we find the most usage and lowest usage of table in Sql Server by T-SQL

how can we find the most usage and lowest usage of table in Sql Server by T-SQL
The table has time stamp column
StartedOn datetime
EndedOn datetime

The Below query has been used , but the textdata column doesnot include the name of the table ServiceLog.
SELECT
FROM
databasename,
duration
fn_trace_gettable('F:\Program
Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Log\log_148.trc',
default)
WHERE
DATABASENAME='ZTCFUTURE'
AND TEXTDATA
IS
NOT
NULL
--AND TEXTDATA LIKE 'SERVICE%'
order
by cpu
desc;
