Comparison between and DB2 in Parallel processing capability

which one is the peter in parallel processing oracle or DB2? what is the differ in the capability between them?

Though not specific to parallel processing, you may wish to check out an Oracle White Paper on comparision between 11g RAC vs DB2 v9 at the following link, which may be of help -

Parallel Process Model Entry

Hello,
First, using LabVIEW 2011 and TestStand 2010 SP1.
We have a custum GUI setup to use the sequential model. At the heart of it, when we hit start, it accesses the Single Pass entry point and runs it with some modifications we've made. Now, we'd like to have a setup that can test multiple DUTs and use the Parallel Process Model. I'd like to have our GUI basically perform the same functions as the built in popup when running the TestUUTs entry point. I've seen the PreUUT callback where you can disable the built in popup. But what I can't seem to figure out is how to initiate a test socket test because it doesn't seem to line up with an entry point necessarily.
When they push the start button next to DUT 0, I want to start socket 0. And if they hit the start button next to DUT 1, I want to start socket 1. What entry point does the GUI use to make this happen? Does the GUI need to start an entry point (IE Test UUTs) then send more information later to start a test? if so, where does TestStand wait for that information within the parallel process model?
Thanks.

One way you could do it is as follows:
Still override PreUUT like in the example and add code which posts a UIMessage synchronously to the UI and then waits for a persocket notification (e.g. you can use the socket index as part of the name to make a per socket notification). Then in your UI, handle the UIMessageEvent on the ApplicationMgr. When you get the UIMessage from your PreUUT you will know it's ready and you can then update your UI to enable the start button, and when the user presses it, you can then Set() the notification to tell the testsocket thread to continue.
for example, in preuut:
Create Notification "MyUIStartNotification Socket 1"
Thread.PostUIMessage(UIMsg_UserMessageBase + 1, RunState.TestSockets.MyIndex, "MyUIStartNotification Socket 1", null, true)
Wait on Notification "MyUIStartNotification Socket 1"
In your UI
Handle UIMsg_UserMessageBase + 1
Enable Start Button
When start button pushed, Set Notification that corresponds to that socket. Pass any data needed with the notification, for example, create a container that contains a serialnumber property and a continuetesting property and pass that with the Set operation. In your PreUUT code get that data from the notification and update your parameters.
Not simple, but doable.

Parallel processing in background

Hi All,
I am processing 1 million of records in background, which takes approximately around 10 hrs. I wanted to reduce the time to less than 1 hr and tried using parallel processing. But the tasks run in Dialog workprocesses and giving abap short dumps due to time out.
Is there any other solutions using that i can reduce total processing time.
Please note that i cannot split. I am getting 1 million records from a select query and after processing all those records in SAP, I am sending to XI and XI will post in legacy system.
Please note that all other performance tunings done.
Thanks,
Rajesh.

Hi Rajesh,
Refer sample code for Parallel Processing:
By doing this your processing time will be highly optimized.
Go thru the description given in the code at each level.
This code Checks available WORK PROCESSes and assigns data in packets for processing. This way you save a lot of time esp when data is in Millions.
Hope it helps.

Process Capability

Hello,
Please note that once we generate Control chart for the Required Characterisitcs.
I would like to know the Table and fields for the Process Capability that is Cp and Cpk .
Please let me know ASAP.
I need to develop a report for the above.
With regards,
shridhar.d
9880644496

Dear SM
1) The CP and CPk that appears in MCXD has no connection with SPC characteristic selection in the control indicator
1) The mic should be single recording
2) To get the Cp, CPK you have to drilldown to either Plant/masterinspchar or Insp. characteristic using the switch drill down option
3) The Mic should have upper and lower limit
The SPC indicator in Mic is used only when you need a control chart is needed.
2) There is another method by which you can get Cp, CPK
Go to QS28. Input the plant and the mic and execute. You will get MIC details. Choose the MIC and click on Result history. A pop will appear Result history Limit Selection. In the Time Tab you can see inspection lot selection date From and To. Execute
You will get the inspection lot list select all and click on histogram and there in that you have tab for statistical values
Hope this helps

Pointers for optimizing system performance (run time) while running DP process chain with parallel processing

Hi Experts,
We are running APO DP process chain with parallel processing in our company, we are experiencing some issues regarding run time of process chain, need your help on below points;
- What are the ways we can optimize process chain run time.
- Special points we need to take care of in case of parallel processing profiles used in process chain.
- Any specific sequence to be followed for different processes in process chain - if there is some best practice followed.
- Any notes suggesting ways to improve system performance for APO version 7 with different enhancement packs 1 and 2.
Any help will be really appreciated.
Regards

HI Neelesh,
There are many ways to optimize performance of the process chains (background jobs) in APO system.
Firstly I would recommend you to identify the pain areas (steps) which are completing with more runtimes. Then each one of the step has got different approaches to decrease the runtime.
Like you may end up with steps like infopackage executions, DTPs, DP mass processing jobs etc which might be running with more runtimes. So now target each one of them differently and find out the ways to optimize. At the same time the approach you follow should be technically possible with basis perspective (system load and utilization) as well.
And coming to parallel processing, you can use parallel processing for different for different jobs. You can further r explore on the same using parallel processing. Like loading an infocube, mass processing, infopackage execution, DTP, TSCOPY etc.
Check the below link for more info

Let me know if you require further info.

Parallel processing for increaing the performance

various ways of parallel processing in oracle especially using hints
Please let me knw if there exists any online documentation in understanding the concept

First of all: As a rule of thumb don't use hints. Hints make programs too unflexible. A hint may be good today, but might make things worse in future.
There are lots of documents available concerning parallel processing:
Just go to http://www.oracle.com/pls/db102/homepage?remark=tahiti and search for parallel (processing)
Due to my experience in 10g, enabling parallel processing might slow down processing extremely for regular tables. The reason are lots of waits in the coordination of the parallel processes.
If, however, you are using parallel processing for partitioned tables, parallel processing works excellent. In this case, take care to choose the partitioning criterion properly to be able to distribute processing.
If, for example, your queries / DMLs work on data corresponding to a certain time range, don't use the date field as partitioning criterion, since in this case parallel processing might work on just a single partition. Which again would result in massive waits for process coordination.
Choose another criterion to distribute the data to be accessed to at least <number of CPUs -1> partitions (one CPU is needed for the coordination process). Additionally consider to use parallel processing only in cases where large tables are involved. Compare this situation with writing a book: If you are planning to have some people writing a (technical) book consisting of just 10 pages, it wouldn't make any sense at all concerning time reduction. If, however, the book is planned to have 10 chapters, each chapter could be written by a different author. Reducing the resulting time to about 1/10 compared to a single author writing all chapters.
To enable parallel processing for a table use the following statement:
alter table <table name> parallel [<integer>];If you don't use the <integer> argument, the DB will choose the degree of parallelism, otherwise it is controlled by your <integer> value. Remember that you allways need a coordinator process, so don't choose integer to be larger than <number of CPUs minus 1>.
You can check the degree of parallelism by the degree column of user_/all_/dba_tables.
To do some timing tests, you also can force parallel dml/ddl/query for your current session.
ALTER SESSION FORCE PARALLEL DML/DDL/QUERY [<PARALLEL DEGREE>];

ABAP OO and parallel processing

Hello ABAP community,
I am trying to implement a ABAP OO scenario where i have to take into account parallel processing and processing logic in the sense of update function modules (TYPE V1).
The szenario is definied as follows:
Frame class X creates a instance of class Y and a instance of class Z.
Classes Y and Z sould be processed in parallel, so class X calls classes Y and Z.
Classes Y and Z call BAPIS and do different database changes.
If classes Y or Z have finished, the status of processing is written into a status table by caller class X.
The processing logic within class Y and class Z should be a SAP LUW in the sense of a update function module (TYP V1).
Can i use events?
(How) Should i use "call function in upgrade task"?
(How) Should i use "call function starting new task"?
What is the best method to realise that behaviour?
Many thanks for your suggestions.

Hallo Christian,
I will describe you in detail, whow I have solved this
problem. May be there is a newer way ... but it works.
STEPS:
I asume you have splitt your data in packages.
1.) create a RFC-FM: Z_WAIT
It return OK or NOT OK.
This FM: does following:
DO.
call function TH_WPINFO -> until the WPINFO has more
than a certain number of lines. (==> free tasks)
ENDDO.
If it is OK ==> free tasks are available
call your FM (RFC!) like this:
CALL FUNCTION <FM>
STARTING NEW TASK ls_tasknam " Unique identifier!
DESTINATION IN GROUP p_group
PERFORMING return_info ON END OF TASK
EXPORTING
TABLES
IMPORTING
EXCEPTIONS
*:--- Take care of the order of the exceptions!
COMMUNICATION FAILURE = 3
SYSTEM_FAILURE = 2
UNFORCED_ERROR = 4
RESOURCE_FAILURE = 5
OTHERS = 1.
*:--- Then you must check the difference between
*:--- the started Calls and the received calls.
*:--- If the number increases a certain value limit_tasks.
wait until CALLED_TASK < LIMIT_TASKS up to '600' seconds.
The value should be not greater then 20!
DATA-Description:
parameters: p_group like bdfields-rfcgr default 'Server_alle'. " For example. Use the F4 help
if you have defined the report-parameter as above.
ls_tasknam ==> Just the increasing number of RFC-Calls
as Character.
RETURN_INFO is a form routine in which You can check the results. Within this Form you must call:
RECEIVE RESULTS FROM FUNCTION <FM>
TABLES: ... " The tables of your <FM> exactly the same order!
EXCEPTIONS
COMMUNICATION FAILURE = 3
SYSTEM_FAILURE = 2
UNFORCED_ERROR = 4
NO_ACTIVATE_INFOSTRUCTURE = 1.
Her eyou must count the received Calls!
And you can save them into a internal table for checking!
I hope I could help you a little bit
God luck

Parallel process with a queue and file?

Hello, first of all sorry for my bad english^^:
I am working for days on my project where I have to show the parallel process while transfering information by different ways and their problems (like timing and so on).
I chose the transmission of information to a parallel process by (1) a queue, and by (2) a file (.txt). (other ways are welcome, do you have 1-2 other ideas?)
To solve this problem I made three while loops, the first one is the original one, where the original information (as a signal) is created and send by queue and file to the other two while loops, where this information is getting evaluted to create the same signal.
so in the end you can compare all signals, if they are the same - so that you can answer the question with the parallelity of process.
but in my vi file i have some problems:
the version with the queue works pretty fine - it's almost parallel
but the version with file doesn't work parallel, and i have no idea how i can solve it - -
i'm a newbie^^
can someone correct my file, so both (file and queue version) run parallel with the original one, or tell me what i can or must do?

A queue is technically never parallell, though you can have several if you really need parallellism. Other methods include Events, Action Engines, Notifiers (and why not webservices) for information transfer between processes.
Due to limitations in the disk system you can only read/write one file at a time from one process, so i wouldn't recommend that. If you use a ramdisk it might work.

Explain Plan - Parallel Processing Degree of 2 and CPU_Cost

Explain Plan - Parallel Processing Degree of 2 and CPU_Cost
When I use a hint to use parallel processing with a degree of 2
the I/O cost seems consistently divided by (1.8) but the cpu cost
adjustment is inconsistent(between 2.17 and 2.62).
Any ideas on why the cpu cost varies with each table ?
Is there a formula to adjust the cpu_cost ?
Thanks,
Summary:
The i/o cost reduction is consistent (divide by 1.8)
Table 1: 763/424 = 1.8
Table 2: 18774/10430 = 1.8
Table 3(not shown): 5/1.8 = 3
But the cpu cost reduction varies:(between 2.17 and 2.62)
Table 1: 275812018/122353500 = 2.25
Table 2: 7924072407/3640755000 = 2.17
Table 3(not shown): 791890/301467 = 2.62
Example:
Oracle Database 10.2.0.4.0
Table 1:
1.) Full table scan on Table 1 without parallel processing.
EXPLAIN PLAN FOR select/*+ CPU_COSTING
PARALLEL(table_1,1)*/
* from table_1
SQL> select cost,io_cost,cpu_cost from plan_table;
IO_COST CPU_COST
763 275812018
2.) Process Table 1 in parallel with a degree of 2.
EXPLAIN PLAN FOR select/*+ CPU_COSTING
PARALLEL(table_1,2)*/
* from table_1
IO_COST CPU_COST
424 122353500
Table 2:
3.) Full table scan on Table 2 without parallel processing.
EXPLAIN PLAN FOR select/*+ CPU_COSTING
PARALLEL(table_2,1)*/
* from table_2
IO_COST CPU_COST
18774 7924072407
4.) Process Table 2 in parallel with a degree of 2.
EXPLAIN PLAN FOR select/*+ CPU_COSTING
PARALLEL(table_2,2)*/
* from table_2
IO_COST CPU_COST
10430 3640755000

The COST value is for the benefit of the CBO; not YOU.
What should be more important to you is the elapsed run time for the SQL

Functional and technical comparisons between JDE version A 7.3 and A 9.3

Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
1. Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak2, Vista, or Windows 7. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
2. Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
3. VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
4. CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

Parallel Processing and Capacity Utilization

Dear Guru's,
We have following requirement.
Workcenter A Capacity is 1000.   (Operations are similar)
Workcenter B Capacity is 1500.   (Operations are similar)
Workcenter C Capacity is 2000.   (Operations are similar)
1) For Product A: Production Order Qty is 4500. Can we use all workcenter as a parallel processing through Routing.
2) For Product B: Production Order Qty is 2500. Can we use only W/C A and B as a parallel processing through Routing.
If yes, plz explain how?

Performance end to end testing and comparison between MPLS VPN and VPLS VPN

Hi,
I am student of MSc Network Security and as for my project which is " Comparison between MPLS L3 VPN and VPLS VPN, performance monitoring by end to end testing " I have heard a lot of buzz about VPLS as becoming NGN, I wanted to exppore that and produce a comparison report of which technology is better. To accomplish this I am using GNS3, with respect to the MPLS L3 VPN lab setup that is not a problem but I am stuck at the VPLS part how to setup that ? I have searched but unable to find any cost effective mean, even it is not possible in the university lab as we dont have 7600 series
I would appreciate any support, guidence, advice.
Thanks
Shahbaz

Hi Shahbaz,
I am not completely sure I understand your request.
MPLS VPN and VPLS are 2 technologies meant to address to different needs, L3 VPN as opposed as L2 VPN. Not completely sure how you would compare them in terms of performance. Would you compare the performance of a F1 racing car with a Rally racing car?
From the ISP point of view there is little difference (if we don't want to consider the specific inherent peculiarities of each technology) , as in the very basic scenarios we can boil down to the following basic operations for both:
Ingress PE impose 2 labels (at least)
Core Ps swap top most MPLS label
Egress PE removes last label exposing underlying packet or frame.
So whether the LSRs deal with underlying L2 frames or L3 IP packets there is no real difference in terms of performance (actually the P routers don't even notice any difference).
About simulators, I am not aware of anyone able to simulate a L2 VPN (AtoM or VPLS).

Comparison between cFP and cDAQ

Hi,
I'm looking for (as much details as possible) a comparisons between compact Fieldpoint and compact DAQ hardware. I'm trying to decide which hardware platforms to use.
TIA

Compact Fieldpoint is for installed, industrial type applications. It has a realtime operating system. The controller runs code to read inputs and operate outputs. The application can be distributed on an ethernet network. There are different modules available for different types of inputs and ouputs.
Compact DAQ also has numerous input and output modules. It is more intended for portable applications. It connects to your PC through a USB port. So the code would need to run on the PC

[AS-CS5] Comparison between text style range and character style

Hi,
It's been a while since I'm not coming on this forum ...
I'm looking to make a comparison between a "text style range" and a character style.
I have no problems, except for the comparison of "fonts".
myCurrentText = text for char…
theStyle = character style id…
I try:
 if (applied font of myCurrentText ≠ applied font of theStyle) then set theCharDifference to 1
The selected text give me:
 font "Minion Pro Italic" of application "Adobe InDesign CS5.5"
and the character style:
 "Minion Pro"
I try "set theTextFont to font of applied font of myCurrentText" -> Error
This is my script (it's too long to post here) <http://db.tt/BLoGPiN>.
Loot at the "on CheckCharacterDifference(myCurrentText, theStyle)"
TIA.
Oli.

I've written this, but I do not know if it covers all cases ...
Someone?
Thanks.
Oli.
set theText to item 1 of selection
set theStyleChar to properties of character style 2
-- analysis of the properties of the text
set myTextFontApplied to applied font of theText
set myTextFontFamily to font family of applied font of theText
set myTextFontStyle to font style of theText
-- analysis of the character style
set myStyleCharFontStyle to applied font of theStyleChar
if myStyleCharFontStyle = "" then
 set myStyleCharFontStyle to font style of theStyleChar
 if myStyleCharFontStyle ≠ myTextFontStyle then set theDifference to true
else
 if myStyleCharFontStyle ≠ myTextFontFamily then set theDifference to true
end if
