Calculate interface bandwidth through WMI Classes

Hi,
I am trying to find bandwidth utilization percent for all interfaces.
Using Win32_PerfFormattedData_Tcpip_NetworkInterface captured
BytesTotalPerSec and Currentbandwidth and
calculating utilization % = ((BytesTotalPerSec*8)/Currentbandwidth)*100 by this formula.
For some times its been observed that utilization percentage is crossing 100%.Is there any way to calculate bandwidth utilization through WMI.
As perfformatteddata contains all cooked values and currentbandwidth is raw value.Is there any issue with the formula i used?

Alos note this about teh counter called "currentbandwidth":CurrentBandwidth
Data type: uint32
Access type: Read-only
Qualifiers:
DisplayName
("Current Bandwidth")
, CounterType
(65536)
, DefaultScale
(-6)
, PerfDetail
(200)
Estimate of the interface's current bandwidth in bits per second (bps). For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this value is the nominal bandwidth.
This is not what you mena bu "currentbandwidth". I think what you are looking for is currernt usage or current bytes/sec.
¯\_(ツ)_/¯

How to calculate bandwidth through Multi-bitrate player

Hello everyone
I want to create multi-bitrate player to play VOD and Live stream.
Now for switch between each video bitrate I have to find currently bandwidth between AMS server and client player.
For get current bytes per second I use netstream info but this not stable to decision for switch between bitrates, also I use netConnection checkBandwidth for get the current bandwidth between client-server and sum this value with current bytes persecond for calculate current bandwidth between them but this values is not stable to decision.
Please advise me to fix this problem.
Thanks in advance.

if the bandwidth is not stable between client and server then "it is not stable" not matter what tool you use to measure...What is your specific question?
The server supplied checkbandwdth method is better way to find out bandwidth and is being used by other customers too to make a switch in case of MBR(Multi Bit Rate).

Weblogic 10.3.2 EJB3 Local Interface in POJO/Helper classes

Hi,
I have a jar file containing all EJB's in application & some Helper classes. I want to access Local interfaces of EJBs in those helper classes. Is there any way I can do it? I've gone through Maxence Button & Jay SenSharma 's blogs about accessing Local interface. but it doesn't help. May be these two guys can help me more here.. My requirement is very simple. Just to access local interface in POJO/Helper classes that are in same JAR file as EJB's. I can't get reference with @EJB class level annotation as Helper classes are called independently from MBean services.. not from any EJB or Servlert.
Please if anyone can tell me how do I get reference of local interfaces, that would be really good.
my environment is

Interfaces for your own classes - do you bother?

Hi All,
before anyone gets upset, I did post a shorter version this to the Java Prog forum a couple of days ago. I'm reposting here because the thread was pushed down the list just as comments were getting interesting, and I was tossing up which forum was most appropriate anyway...
OK, I'd like to pose a general question on the use of interfaces with your own classes. I am totally behind the concept of using appropriate interfaces for declaration of vars, parameters etc (i.e. use "List" rather than "Vector"), but what about your own classes?
If I have a class in my application that doesn't fit into any kind of framework or class hierarchy, subclass of object basically, should I write an interface with all the same method sigs and use that rather than the class for my vars, params etc? This would make things more flexible in future, enabling you to swap classes in and out of your app more easily.
Taking it a step further, how's this for a design methodology: For every class you write (once again classes that don't fit into your own or somebody else�s hierarchy or framework) do the following
1. Create an interface (MyInterface) that maps 1 to 1 to that class (MyClass), with all the same method sigs.
2. Make the constructor private and manage all the creation of instances of MyClass through a factory that returns objects of type MyInterface.
If you do this there will be no mention of any of your concrete classes anywhere in your app except the factories, making it easier to refactor etc. Do this for all your classes.
A little sketchy but I hope you get idea. Is this complete overkill? Is there a down side to this? Does anyone do anything like this?
Cheers
Matt

Although the pattern you describes adds flexibility, it also adds complexety.
Imagine somebody is looking at your code and from what he sees he deducts that the next thing to look at is the concrete class which is used at a given place.
If you used an interface, he must find out which implementing class is actually used at this place. It's not a big thing, but if every single class has its seperate interface and factory I would consider it overkill ... after all you have to write all the boring code for this.
In the case of doubt I'd agree it's better to throw in an interface and a factory instead of refactoring thousand lines of codes afterwards. But if nothing hints toward a second implementation of the interface, or another reason for using an interface don't bother to write one.
As a general rule I use something like: Don't use a general rule. ;-)

Diffrence between a Interface and a abstract class?

Hi OO ABAP Gurus
Please clear below point to me.
Diffrence between a Interface and a abstract class?
Many thanks
Sandeep Sharma..

Hi
Abstract classes
Abstract classes are normally used as an incomplete blueprint for concrete (that is, non-abstract) subclasses, for example to define a uniform interface.
Classes with at least one abstract method are themselves abstract.
Static methods and constructors cannot be abstract.
You can specify the class of the instance to be created explicitly: CREATE OBJECT <RefToAbstractClass> TYPE <NonAbstractSubclassName>.
Abstarct classes themselves cant be instantiated ( althrough their subclasses can)
Reference to abstract classes can refer to instance of subclass
Abstract (instance) methods are difined in the class , but not implemented
They must be redefined in subclasses
CLASS LC1 DEFINAITION ABSTARCT
PUBLIC SECTION
METHODS ESTIMATE ABSTARCT IMPORTING
ENDCLASS.
Interfaces
Interfaces only describe the external point of contact of a class (protocols), they do not contain any implementation.
Interfaces are usually defined by a user. The user describes in the interface which services (technical and semantic) it needs in order to carry out a task.
The user never actually knows the providers of these services, but communicates with them through the interface.
In this way the user is protected from actual implementations and can work in the same way with different classes/objects, as long as they provide the services required. This is known as polymorphism with interfaces.

Reading the Interfaces name which the class is implementing in a COM dll is implementing.

Hi All,
I'm using .NET Reflection to read a COM dll. I'm able to fetch the classes that are present in the dll. But I would like to know interface name which this class is implementing.
For a .NET dll we can know the name of class's implementing interface name using the <classname>.BaseType.Name property.
How can I know the interface name which this class is implementing (if any).
Please let me know how to do this for a COM dll.
Thanks in advance,Satish
Thanks, Satish Bommideni "Success usually comes to those who are too busy to be looking for it."

Hi,
Thanks for the reply.
I'm reading the COM assembly using the methods available in oleaut32.dll.
Also I've imported the namespaces
System.Runtime.InteropServices.ComTypes;
System.Runtime.InteropServices;
to use its respective methods and thus I'm able to read it's classes.But donot know what property to check for this class's interface.
Kindly let me know if you need any further information.

Interface Mapping Object - No class definition found

Hi
I have created a simple Interface Mapping in the Integration Repo. When i try to TEST the interface mapping i get class not found errors.See the stacktrace below.
LinkageError at JavaMapping.load(): Could not load class: com/sap/xi/tf/_PO_MAPPING_
- java.lang.NoClassDefFoundError: Illegal name: com/sap/xi/tf/_PO_MAPPING_
Looks like some standard sap packages are missing from the CLASSPATH. Anyidea where it has to be specified ?
PO_MAPPING is the message mapping object i have created and the test is successful for this object.However when i reference it in Interface Mapping , i get the above errors.
I suppose XI generates Java Code when i create these objects and the mappings.Any idea where the JVM seems to reference these packages and How to rectify it ?
Thanks

Send mail through CL_BCS class with normal priority

Hello guys!!!
I'm trying to send email through CL_BCS class, and it's work fine!
But, always sent with high priority, and I need to send whith normal priority.
I tried this:
DATA: o_send_request TYPE REF TO cl_bcs,
        o_document     TYPE REF TO cl_document_bcs.
o_document = cl_document_bcs=>create_document(
                 i_type       = 'HTM'
                 i_text       = msgbody
                 i_subject    = subject
                 i_importance = '5' ).
And this:
CALL METHOD o_send_request->send_request->setu_priority
    EXPORTING
      i_priority = o_send_request->cp_priority_normal.
Unfortunately, don't works.
Any idea?
Thanks!!!
Kleber S. Kiefer

Hi,
Please try the following solution:
* set mail importance to normal
TRY.
lo_document ?= lo_send_request->document( ).
lo_document->set_importance( i_importance = '5' ).
CATCH cx_sy_move_cast_error.
ENDTRY.
In addition, in the Alert framework, which send emails with high priority, it controls the document's importance and then send out the emails with high priority.
* create send request, document etc..
    TRY.
        lo_document = cl_document_bcs=>create_document(
                              i_type = l_texttype
                              i_text = lt_text

Create Attachment in workflow through ABAP Class in ECC 5.0

Hi,
Wr are using SAP ECC 5.0 and i am trying to create attachment through ABAP class.
Here in ECC 5.0, macro INCLUDE cntn01_swc is not available.
I am getting an error in declaration of SOFM object, because again SWC0_OBJECT is not available.
I've tried creating the parameter as type SOFM and of type table of SOFM but it also not working.
Can anybody help me how i can create SOFM instance in ABAP class in ECC 5.0?
Regards,
Smit

Hi
I am not very much sure about ECC 5.0 environment. Firstly are you looking to create a SOFM object inside any class or program or Function module , If yes then you need to include a include INCLUDE CNTN01_SWC (No arrow brackets) if this include is not available then use INCLUDE<CNTN01> then declare a variable of type SWC0_OBJECT if you are using first include or declare of type SWC_OBJECT.
Once you include any of the includes then by making use of SWC macros you can create a object
SWC0_CREATE_OBJECT <VARAIBLE> <BOR NAME> <BORKEY> for first include.
SWC_CREATE_OBJECT <VARAIBLE> <BOR NAME> <BORKEY> for second include.

How to calculate usage value through measuring document.

Hi,
While creating Sales Order with reference to a Contract i need to update the usgae value in the Order Quantity ( RV45A-KWMENG ) field (at line item level).
Can you help me calculate usage value through measuring documents for equipment over a period of time.
Is there any function module for the same?
Thanks.

Hi,
To determine the usage value of a an equipment I had followed the following.
From table STPO, check if the material receipted belongs to a standard BOM (STLTY='S')
If yes, record the BOM (STLNR) and the BOM item node number (STLKN)
From PLMZ table, select the task list type (PLNTY), the key for task list group (PLNNR), the group counter (PLNAL), the task list node number for operation (PLNKN), if the record is not flagged for deletion (LOEZ)
From PLFH table, select the object type of the CIM resource (OBJTY), the object id of the resource (OBJID), the usage value (EWVGW) if the record is not flagged for deletion (LOEZ)
From CRVE_A table, select the equipment number (EQUNR)
The result of this selection will be all the tools which can be used for the production of the material receipted.
The measuring point for this or these equipment(s) will be selected from equipment number and EQUI table
The result of this selection will be all the measuring point to update.
Create new measurement document for the selected measurement point (transaction IK11)
Technically go as follows:-
MAT = material receipted
Select STLY, STLNR, STLKN from STPO table where IDNRK='MAT' and STLTY='S'
If results exist
Select STLTY, PLNNR, PLNAL, PLNKN from PLMZ where PLMZ.STLTY=STPO.STLTY and PLMZ.STLNR=STPO.STLNR and PLMZ.STLKN=STPO.STLKN
And PLMZ.LOEZ<>'X'
Select EWVGW, OBJTY, OBJID from PLFH twhere PLFH.STLTY=PLMZ.STLTY and PLFH.PLNNR=PLMZ.PLNNR and PLFH.PLNAL=PLMZ.PLNAL and PLFH.PLNKN=PLFH.PLNKN and PLFH.LOEKZ<>'X'
USAGE=PLFH.EWVGW
Select EQUNR from CRVE_A where CRVE_A.OBJTY=PLFH.OBJTY and CRVE_A.OJBID=PLFH.OBJID
All the equipment number selected at this moment will be called EQUIP in the next steps
EQUIP= Equipment number previously selected
Select OBJNR from EQUI where EQUNR=EQUIP
Select PARNR from IHPA where OBJNR=EQUI.OBJNR
If PARNR = Vend then
Select IMRC_POINT from equi where equnr=equip
All the measuring points selected at this moment will be called MEASP in the next steps
For each MEASP
Insert into IMRG the new increment value (USAGExMAT) in field CDIFF
Remark: the field CDIFF is managed in floating point number, accurate to 8 bytes.
I hope this is useful for you.

How to calculate network bandwidth for dataguard 11.2

Hi all,
have a customer who needs to setup a new data guard environment in release 11.2.0.2. Primary site will be in Italy, standby site will be in New York.
He would like to know the network bandwidth between primary and standby site needed to obtain the maximum performance in redo transport with or without compression option.
I found a lot of threads and docs indicating some formulas but none of them explained how to:
- calculate network bandwidth on a rac system (having a single instance standby database)
- calculate network bandwidth in case of use redo transport compression
- calculate cpu consumption if using redo transport compression
Could you please give any advice?
A.M.

Hi,
customer made ma a lot of technical question just like the following:
- which are the main factors determining the 30% overhead indicated in the network bandwidth calculation
Required bandwidth = ((Redo rate bytes per sec. / 0.7) * 8) / 1,000,000 = bandwidth in Mbps
- how much bandwidth will I gain if I apply redo transport compression and why redo transport compression and why usually the gzip utility gives me 5X less and oracle compression gives me a maximum of 50-60% of compression even if it uses the same engine of zlib compression as indicated below?
Data Guard redo transport compression uses the same zlib compression engine at level 1 as gzip -1. To estimate the compression ratio you can achieve using Data Guard redo transport compression, first compress an archived redo log file with gzip:
$ gzip -1 <archive redo logfile>.arc
Then use the gzip --list option to explicitly display the compression ratio:
$ gzip --list <archive redo logfile.arc>.gz
Note: Use gzip version 1.3.3 or later. Refer to www.gzip.org for the latest information on gzip.
Could anyone give me any direction?
Thank you

Unusual use of interface defining static factory class with getInstance

This question is prompted by a recent New to Java forum question ask about the differences between Interfaces and Abstract classes. Of course one of the standard things mentioned is that interfaces cannot actually implement a method.
One of my past clients, one of the 500 group, uses interfaces as class factories. The interface defines a pubic static class with a public static method, getInstance, that is called to generate instances of a class that implements the interface.
This architecture was very object-oriented, made good use of polymorphism and worked very well. But I haven't seen this architecture used anywhere else and it seemed a little convoluted.
Here is a 'pseudo' version of the basic interface template and use
-- interface that defines public static factory class and getInstance method
public interface abc {
    public static class FactoryClass
        public static abc getInstance ()
            return (abc) FactoryGenerator(new abcImpl(), abc.class);
-- call of interface factory to create an instance
abc myABC = abc.Factory.getInstance();1. Each main functional area ('abc' in the above) has its own interface factory
2. Each main functional area has its own implementation class for that interface
3. There is one generator (FactoryGenerator) that uses the interface class ('abc.class') to determine which implementation class to instantiate and return. The generator class can be configured at startup to control the actual class to return for any given interface.
I should mention that the people that designed this entire architecture were not novices. They wrote some very sophisticated multi-threaded code that rarely had problems, was high performance and was easy to extend to add new functionality (interfaces and implementing classes) - pretty much plug-n-play with few, if any, side-effects that affected existing modules.
Is this a best-practices method of designing factory classes and methods? Please provide any comments about the use of an architecture like this.

Thanks for the feedback.
>
I don't see how 'the generator class can be configured at startup to control the actual class to return for any given interface' can possibly be true given this pseudo-code.
>
I can see why that isn't clear just from what is posted.
The way it was explained to me at the time is that the interface uses standard naming conventions and acts like a template to make it easy to clone for new modules: just change 'abc' to 'def' in three places and write a new 'defImpl' class that extends the interface and the new interface and class can just 'plug in' to the framework.
The new 'defImpl' class established the baseline functionality that must be supported. This line
return (abc) FactoryGenerator(new abcImpl(), abc.class);uses the initial version of the new class that was defined, 'abcImpl()', when calling the FactoryGenerator and it acted as a 'minimum version supported'. The generator class could use configuration information, if provided, to provide a newer class version that would extend this default class. Their reasoning was that this allowed the framework to use multiple versions of the class as needed when bugs got fixed or new functionality was introduced.
So the initial objects would be an interface 'abc' and a class 'abcImpl'. Then the next version (bug fixes or enhancements) would be introduced by creating a new class, perhaps 'abcImpl_version2'. A configuration parameter could be passed giving 'abcImpl' as the base class to expect in the FactoryGenerator call and the generator would actually create an instance of 'abcImpl_version2' or any other class that extended 'abcImpl'.
It certainly go the job done. You could use multiple versions of the class for different environments as you worked new functionality from DEV, TEST, QA and PRODUCTION environments without changing the basic framework.
I've never seen any Java 'pattern' that looks like that or any pattern where an interface contained a class. It seemed really convoluted to me and seems like the 'versioning' aspect of it could have been accomplished in a more straightforward manner.
Thanks for the feedback. If you wouldn't mind expanding a bit on one comment you made then I will mark this ANSWERED and put it to rest.
>
I don't mind interfaces containing classes per se when necessary
>
I have never seen this except at this one site. Would you relate any info about where you have seen or used this or when it might be necessary?

WMI Class Reference for Dynamics CRM Performance Counters

Hello,
I am trying to monitor a MS Dynamics CRM 2013 instance using the
Performance Counters provided.
I will be writing VB Script to collect the performance counter data via WMI.
I couldn't find out the WMI class reference the Dynamics CRM 2013 performance counters.
What I meant was, some thing similar to the 'Windows Server Cluster' Object and Performance counter class, as given below.
https://msdn.microsoft.com/en-us/library/aa965285%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396
Help me on this.
Regards,
Krishna.

Hi David,
Sorry for posting in the wrong forum. Will correct it in future.
I can't use the Perfmon as I have a java application which will call the VB Script periodically to collect the data. I need to write both VB Script and Powershell scripts. I need to have the class reference to understand the data type of each attribute in
a performance counter. For ex,
The 'CRMAuthentication' counter has the following attributes.
Caption
ClaimsAuthenticationAttemptsInTheLastMinute
ClaimsAuthenticationFailuresInTheLastMinute
Description
It is necessary to understand the datatype each attributes in the all Performance Counters.

Krishna.
