LLQ and CBWFQ Functionality During Non-Congestion

Question... During times of no congestion on an interface with LLQ configured, is the bandwidth truly reserved for the LLQ queue? Or can other traffic classes use as much bandwidth as they need until there is congestion? For example, we have a FastEthernet interface with a LLQ queue defined for 50% of the bandwidth. Does that mean that even if the traffic defined in the LLQ (voice for example) is only using 1Mb that there is 49Mb of wasted bandwidth that other traffic classes can not use? Or does the LLQ bandwidth only come into play if/when there is congestion on the interface?

I consider you have congestion anytime a frame/packet needs to be queued.
As your later post describes, congestion issues can be on a micro time scale, i.e. multi-second to subsecond, and are often "invisible" to higher monitoring tools monitoring on multi-minute time scales.
A short term high transmission ingress rate can often easily overflow a slower egress's queue.
Resulting drops may cause a fast sender to slow/pause (a lot) which lowers its average transmission rate - this also will "hide" the issue from "bandwidth" monitoring.

Help on drag and drop function

Hi guys,
I have a problem creating a drag and drop function for a certain task. The task is as stated below:
1. Create a VI that enables a user to drag and drop multiple image files into it.
2. I was thinking of storing all the file names into an array of file names
3. VI will then convert the image format into an array of 1024 by 768 binary numbers.
Task number 3 I have already done but I'm struggling with this drag and drop function (Task 1 and 2) and I have read a couple of entries regarding drag and drop function but none fits my specifications.
In the meantime I can only allow 1 file to be opened by a user at a time and it is quite frustrating if the user has to open like 10 files. He will need to navigate to the folder, select the file, click ok and repeat this for 10 times.
Hence, I need your help to guide me to create a drag and drop function that allows me to open a file and select all the images 1 want at 1 time.
Further information: I am using IMAQ to do the image processing.
Thanks in advance.

QoS apply during congestion and non-congestion

Hi,
Please spare few minute to read and will grateful to receive a quick and short answer for every ?.
Real-time applications, such as voice or interactive video is given priority or preferential services but only during the congestion. Right? With significant amount of bandwidth available can congestion still exist? And traffic types such as voice, video still be given priority or not? Traffic such as voice, video is still prone to delay or latancy or drop even if the interface is high speed?
If there is NO congestion on the outgoing interface, traffic types such as voice, video and data will be sent to the default queue (A separate queue) or their respective queues? Reason it will not be sent to respective queues because when no congestion exists, so QoS doesn't function? Means no congestion management (Queuing tools will come into play and no Queues will receive any packet ). Right?
If it is a default queue (A separate queue) in what order do these three types of packets will leave the router? Is it FIFO?
The overall objective of QoS is to de-queue the packets but pre-requirement for de-queuing is that a queue must form. Since there is NO congestion on the outgoing interface no de-queuing is required. so NO QoS. Correct?
Thanking you!
Saurabh

Real-time applications, such as voice or interactive video is given priority or preferential services but only during the congestion. Right? What's given priority or preferential treatment depends on QoS policy but yes, normally it "triggers" with congestion. With significant amount of bandwidth available can congestion still exist? Yes, if you consider congestion anytime frames/packets are queued, this can happen if there's more ingress ports than egress ports or if ingress has more bandwidth than egress. And traffic types such as voice, video still be given priority or not? That depends on QoS policy. Traffic such as voice, video is still prone to delay or latancy or drop even if the interface is high speed? Yes.
If there is NO congestion on the outgoing interface, traffic types such as voice, video and data will be sent to the default queue (A separate queue) or their respective queues? No, because if there's no congestion there's no queueing. I.e. queuing equals congestion (although it may not be adverse to application). Reason it will not be sent to respective queues because when no congestion exists, so QoS doesn't function? Not all QoS depends on congestion. Means no congestion management (Queuing tools will come into play and no Queues will receive any packet ). Right? Again, no congestion means there's no queue management.
If it is a default queue (A separate queue) in what order do these three types of packets will leave the router? Is it FIFO? All queues are FIFO, but you may be confusing the default class which might support multiple queues.
The overall objective of QoS is to de-queue the packets but pre-requirement for de-queuing is that a queue must form. Since there is NO congestion on the outgoing interface no de-queuing is required. so NO QoS. Correct? Again, not all QoS is queuing related, for example, policing.

Resource availability during Non-Working Hours and Weekends

Hi Gurus,
Aim: Make the Resource available during Non-Working Hours and Weekends
Requirement: CRP functionality enabling
In CRC2 I have selected capacity tab and in capacity header under 'Change Interval and Shifts' button. I have Inserted a new Interval period and given the validity from/to dates(Non-Working day - Saturday) and Saved.
When i execute the Capacity Planning CM01, there is no change. The Resource availability still shows as "0"hrs for this particular date and for rest of the days it shows as 8hrs.
I have checked the same even after executing the MRP, No change in Capacity Planning Overview - Still the available Capacity Showas as 0
Please guide me, how can i use my resource during the holidays. Means make the system understand that the defined day is a working day though it is holiday as per factory calendar
Please correct me whether am i missing any settings or i should follow some other logic
Regards,
Tam

Hi Partha,
In workdays i dont have any such option "2"
As per standard list I could see only 3 entries in the possible values(F4) popup
"Blank" - Working days according to factory calendar
"0" - Non-Working days(Overrides factory Calendar)
"1" - orking days(Overrides factory Calendar)
I have even tried with option "0" and "1" its still the same, when i enter the period From and To date the fields for the entries Shift start and end date, workday, Shift Seq, Length of the shift, No.of shifts.........are jumping to the next line item.
Because of which i understand that the entered values is not corresponds to the newly defined period
Pls guide me to how to make the resource available during non working days

Problem with tpcall and tpgetrply functions

Hi,
I have a problem with tpcall() and tpgetrply() functions.
In this example (invoke tpcall()):
FBFR32 *buf;
FLDLEN32 buflen;
buf = a_buffer.getBuffer(); /* getBuffer() returns FBFR32* */
buflen = a_buffer.getLongitud();
/* at this point: buf == a_buffer.getBuffer() */
if (tpcall(a_contenedor.getServname(),
(char*)a_contenedor.getBufferPeticion()->getBuffer(),
a_contenedor.getBufferPeticion()->getLongitud(),
(char**)&buf,
(long*)&buflen,
0) == -1)
if (tperrno != TPESVCFAIL)
LANZAR_EXCEPCION(CADENA_WHAT_SB,
"Error en funcion Execute(), llamada tpcall()",
tpstrerror(tperrno))
/* at this point: buf != a_buffer.getBuffer() */
tpcall() function change the memory address of buf. What is the problem? Is wrong my code? Is a problem with tuxedo version?
My tuxedo version is:
tmadmin -vINFO: BEA Tuxedo, Version 8.0, 32-bit, Patch Level 306
INFO: Serial #: 650522264137-773290431251, Expiration NONE, Maxusers 150
INFO: Licensed to: Telefonica Moviles Espa?a, S.A.
INFO: 56-bit Encryption Package
Thanks,
ANTONIO.

There's nothing wrong with your code or tuxedo. tpcall (and tpgetrply) can change the address of the return buffer if it needs to allocate more memory to hold the data. This is the reason why you pass a pointer to the buffer as the output buffer parameter to tpcall and tpreturn. Everything is working as expected.

Why the step-and-repeat function (command+d) isn't working in Illustrator CS5?

Why the step-and-repeat function (command+d) isn't working in Illustrator CS5?
I am trying this. Take an object, move it some inches on the right while holding the option key, so I duplicate it.
Usually, I pressed on command+d to duplicate this action on and on (duplicate the object and moving it some inches away), but now it is not working.
any idea?

kwakoo,
It may be time for the list:
The following is a general list of things you may try when the issue is not in a specific file, and when it is not caused by issues with opening a file from external media. You may have tried/done some of them already; 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
If possible/applicable, you should save current artwork first, of course.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to at least 5 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible), for CS3 - CC you may find the folder here:
https://helpx.adobe.com/illustrator/kb/preference-file-location-illustrator.html
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall (ticking the box to delete the preferences), run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.

Unable to use "drag and drop function" from outlook

We are changing from Lotus to outlook and this has made a problem with getting pdf-files into OAWD directly .
Procedure was like this in Lotus
1. We get documents (FI, F-43, aso ) by email
2. We use OAWD function "drag and drop" , document is attached to a document type and workflow is triggered
3. We pick up documents from Business workplace , handle the document and send it to the approver (who earlier got it directly in their mailbox "lotus")
so far so good , everything worked well
Unfortunately we changed to outlook, non attached files can be "drag and dropped" into OAWD (I understand the part about outlook is showing links instead of "real" pdf and know this is part of the problem)
My question, it can not be possible that we have to manually save the documents/attached files from outlook into "desktop" to later use the drag and drop function?
I have read about the programms to solve problem , ex "inPuncto", but our experts says there will be problem with connector to workflow from OAWD.
I have my greatest doubts about that because this must be really two diffrent moduls, one for converting from outlook and the other must be unchange (undependent of the earlier procedure). SAP can not know from what program the documents will be dragged?
Suggestion about some OAWD-adaptor ?
Any suggestions about great solutions ?

it seems there is no way.
See note 1797073
Is there someone with a better solution?

Advanced functions,UDF's and node function

Dear all,
Can you kindly let me know about Advanced functions,UDF's and node function.Differences and Uses.
Also Let me know about the advantages,Disadvantages of Graphical,XSLT,Java,ABAP and ABAP XSLT mappings.
Thanks,
Srini

Hi,
The term Mapping means:
1. The transformation process, and/or
2. The transformation rules.
Independently from XI, you can distinguish two different mappings
Structure mappings transform entire message structures.
Value mappings transform values within messages.
Mapping Programs to Map Messages :
Message Mapping
Designed by using the graphical mapping editor of Integration Builder
Result: Generated Java Code.
Imported Archives
Import externally defined mapping programs into repository
Java mapping:
Implemented by using a specific interface
XSLT mapping:
Runtime supports XSLT processor
Java methods can be called from within a Style Sheet
ABAP Mapping
You can execute mapping programs in a sequence
The exchange infrastructure supports three types of mappings:
Message mappings that can be designed using a graphical mapping editor in the Integration Builder. As a result, Java code is generated from the graphical representation that is compiled before it can be executed on the integration server.
You can implement your own Java mapping by implementing a specific interface of the mapping API.
You can implement an XSLT mapping
For the latter two, there is no tool support in XI. It is expected that they are developed using external development tools. To make them available for the integration server, they have to be imported into the integration repository as JAR
files before (JAR: Java Archives).
Developers can even decide to combine the different mapping technologies:
Message mappings, XSLT mappings and Java mappings can be combined in a sequence by means of an interface mapping.
XSLT mappings can use java functions
Message mappings support user-defined functions that can use imported java packages of the same namespace.
In SAP XI, there is 3 types of mappings. Namely
XSLT Mapping
Java Mapping
ABAP Mapping
Here is the details of each mapping.
XSLT Mappings (ABAP Engine)
Interface descriptions are in the form of XML documents. XSL Transformation (XSLT) is a member of the XML family of languages. It describes how an XML structure is transformed into another XML structure.
Customers can develop an XSLT mapping by using the Transformation Editor of the ABAP Workbench. Such XSLT mappings are executed at runtime on the ABAP Engine of the Integration Server.
To simplify matters, this section refers to XSLT mappings of the ABAP Engine as transformation programs to differentiate them from XSLT mappings from imported archives that are executed on the J2EE Engine.
Features
XPath and <xsl:include>
You can define mappings using XSLT together with XPath. XPath is also a specification of the XML family. Using XPath you can address any node in an XML document. XSLT implements XPath expressions to select substructures of an XML document. Using templates in XSLT you can define the mapping rules for the selected substructures.
You can use the XSLT tags <xsl:include> and <xsl:import> to include predefined templates for substructures in a complete mapping definition. In this way, you can reuse mappings for data types.
Java Mapping
You can implement mapping programs in Java. To process XML documents, use Java API for XML Processing (JAXP), for example. The JAXP supports the Document Object Model (DOM) and the Simple API for XML (SAX). This gives you great flexibility for mapping definitions with Java.
Implementation Considerations
Java mapping programs are not permitted to be stateful. You are therefore not permitted to perform actions such as writing data to a database table during a Java mapping. The Integration Server cannot track such side effects. Therefore, if an attempt is made to resend a message that has not been received by the receiver, the data may inadvertently be written to the database twice in a Java mapping.
If you use JRE classes in your Java mapping programs then the same program restrictions apply as for Enterprise Java Beans (EJBs). For a detailed description of these restrictions, see the relevant EJB specification. It is important that you also refer to the information under Scope of Functions in Runtime Environment (Java Mappings).
The runtime environment for Java mappings has an mapping API. To use Java mapping, you must define a Java class that implements the Java interface com.sap.aii.mapping.api.StreamTransformation. This interface has two methods:
● public void execute(java.io.InputStream in, java.io.OutputStream out)
At runtime, the Integration Engine calls this method to execute a mapping. This method contains an input stream for the source document and an output stream for the target document as parameters. These streams are usually XML documents. You can import the substructures to be converted from the input stream and output the converted target document in the output stream.
● public void setParameter(java.util.Map param)
The Integration Engine transfers parameters to the mapping program with this method. It evaluates these parameters at runtime in the method execute(). This enables you to control the process flow of the mapping.
The transferred object that implements the Java interface java.util.Map contains seven key/value pairs as parameters. These correspond to corresponding fields in the message header. Apart from the MAPPING_TRACE constant, the value objects are of type java.lang.String. The key objects are defined in the class com.sap.aii.mapping.api.StreamTransformationConstants
ABAP Mappings
ABAP mappings are mapping programs in ABAP objects that customers can implement using the ABAP Workbench.
Features
An ABAP mapping comprises an ABAP class that implements the interface IF_MAPPING in the package SAI_MAPPING.
Exception: CX_MAPPING_FAULT
Applications can decide themselves in the method EXECUTE how to import and change the source XML document. If you want to use the XSLT processor of SAP Web AS, you can use the ABAP Workbench to develop a stylesheet directly (see XSLT Mappings (ABAP Engine)) rather than using ABAP mappings.
Runtime Constants
In ABAP mapping you can read access message header fields. To do this, an object of type IF_MAPPING_PARAM is transferred to the EXECUTE method. The interface has constants for the names of the available parameters and a method GET, which returns the respective value for the parameter name. The constants are the same as in Java mappings, although the constant MAPPING_TRACE does not exist for ABAP mappings. Instead, the trace object is transferred directly using the parameter TRACE of the method IF_MAPPING~EXECUTE
Example: Accessing a Runtime Constant
Method IF_MAPPING~EXECUTE.
Get mapping constant SENDER_SERVICE
data: l_sender_service type string.
l_sender_service = param->get( IF_MAPPING_PARAM=>SENDER_SERVICE ).
ENDMETHOD.

I want to edit properties of the interface windows opened while "Open File", "Save Page As" and interface opened during Downloading of any file.

I am doing a small project on dedicated web client where in user automatically logs in non-root user and Firefox automatically starts.
I am using Fedora 14 kernel 2.6.35.12-88.fc14.i686 and Firefox 3.6.16.
I have installed only Gnome in my computer with no Nautilus or other file browser on it.
I want to edit properties of the interface windows opened while "Open File", "Save Page As" and interface opened during Downloading of any file.
Please guide me for this.

First, I sent an email to the author of PhotoME to inform him of the serious issues his addon caused with Firefox latest versions.
Now, for those of you who do not have the PhotoME addon and yet experience the same problem that I had and that I described above, I suggest the following strategy.
As PhotoME did cause these problems with Firefox latest versions, I am pretty covinved other addons probably might cause these problems too. Therefore, adopt the following method.
Test one addon at a time to see if this particular addon is behind your Firefox issues like the ones I had.
So, disable one addon only at a time. Then close your Firefox and restart it from scratch and see if you still have your Firefox problems. You must restart the Firefox browser from scratch. If you still have these Firefox problems, re-enable the disabled addon, restart your Firefox (again!) and repeat the same method for every single addon that you have.
Try to be selective by choosing first addons that are more likely to cause your Firefox problems such as not very well-known or not very popular addons (like it was the case for the PhotoME addon).
If this method works or if it does not work, report it on this web page so that others can be helped with your comments.
I hope this method will help you because I was really upset that I had these Firefox problems and I first thought it was the fault of Firefox, only to discover later that this PhotoME addon was the culprit and had caused me such upset.

What is the difference between the normal function module and bapi function

hi,
what is the difference between the normal function module and bapi function module.

Hi
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.

Anji

I am using a 6024E DAQ Card. Software is done in VB5. When closing the application is there anything that I have to do to close the card or just simply exiting is OK ? I am just using the AIRead_Scan and DigInPort functions.

When using the 6024E DAQ card, with VB5, is there anything that one has to do to close / shutdown the card before exiting the application. The application only uses AIRead_Scan and DigIn_Port functions.
Raghunathan
LV2012 to Automate Hydraulic Test rigs.

Hello,
You won't need any other functions after AI_Read_Scan or after DIG_In_Prt since both functions are for none buffered acquisitions.
For more information, I recommend that you take a look at the shipping examples that get installed under the folder C:\National Instruments\NI-DAQ\Examples
Good luck with your application!
