About the procedure to implement synchroniztion

hi
I have a question about the actually procedure of doing synchronization in java, I didn't find any acticle to discuss the detail about which methods are called during the whole process.
any body if has some idea, can you help me out?

these are the boxes that open up:
I am unsure as to wether I need to unistall and start again but then worry about the vast amount of songs already in the folder that I would have to reload.

Asking about the procedure of class loading.......

I knew the procedure was like this:
1. Bootstrap classes
2. Replace JDK implementation: <java_home>/jre/lib/endorsed
3. Intstalled extensions: <java_home>/jre/lib/ext
4. class path
I am confused about the function of step 2 and 3
what is the difference of relacing ur original JDK and using Installed extensions???
It is understandable about you want an extension to your JDK, but relacing JDK seems no difference with extension
thx for furthur responds

Sorry for posting again,
but does any one know, for example, calling the same
static method from the same name class, according to
the classloading list (in the 1st post), will the JVM
use the class at step 1 or 2??That has nothing to do with class loadiing.
When the class is loaded it is loaded. Either it is all loaded or it isn't. And you can't call a method, any method, without it being loaded.
>
PS. I know, in general, the 1st class that the JVM
finds in the classloading procedure will be used,
but, step 2 says "Replace JDK implementation", so I
wonder whether the classloading procedure would
actually be the 2nd step first and 1st step secondThere is no 'replacement'.

Fuzzy about the JDBC Vendor implementation

I was confused about the logic behind in Making the connection object. The implementation is provided by the vendor. Can any one please explain the process on how the entire connection object works and the call back methods works on the Driver's implementation.
Is RMI, IIOP, Corba any of these technologies are behind this? Seriously don't know!
I tried to google, yahoo... etc... but all provide info on how to implement the JDBC through the coding. I need to know how the url is parsed/passed over the network and therein the queries and again how it identifies the client from where the query was invoked? Is there an one to one communication channel established between the client and the server? No answers!!!!
Can anyone please help me out from this fuzzy question (May be the question is silly), but i'm interested in knowing the way the communication between Java and the DB server implementation.
Thanks,

Atleast, I would like to know about the common implementationThere is no common implementation. It is whatever it is.
Definitely Socket and TCP\IP protocol would be used, Likely yes for type 4.
But I'm also thinking that definitely the RMI and CORBA concepts would also be used while communicating from client to db server.No. I mean it is possible but I have never seen it. The server would have to support Java natively for it to work as a type 4 driver.
You might find such a thing in a type 3 driver.
I would like to know how the flow of the messages/objects occur in the network. But why?
Anyway. If you want to know there are plenty of open source JDBC drivers. Open one up an look for yourself. MySQL and the JTDS driver come to mind. Both of these use plain java.net.Sockets and then speak the protocol that is native to the database. So the MySQL protocol, or the TDS protocol.
I still don't know why you are asking this question, if you are having a problem or just want to know. If you are having a problem you should tell us what it is. If you just want to know better to look for yourself at the source I would say.

How can I inform all visitors of my website about the procedure they have to follow in order to open my website on mozilla?

I got an answer which unfortunately does not help me. All other search engines work without these necessary information! It is impossible to inform all visitors of my website that they have to do the procedure you mention me. If somebody only have firefox and want to visit my website, he only see that the site www.picchio-art.com does not work! Can you please help me further? Thank you very much!

How to get the procedure/query details for the corresponding transaction id

Hi,
Is it possible to know the transaction details like (procedure/query) from the correcponding local transaction ID? (for eg:10.10.50935)
I am working on ORA-01591 issue (lock held by in-doubt distributed transaction) and got the details of in-doubt transactions from dba_2pc_pending view. Further I would like to get additional details about the procedure name and query who is triggering the issue.
Thanks

Hi Sybrand,
The response is not of much help. Can you please tell me in more detail.
Suppose a transaction is completed long back (say 5 days ago) and I have a transaction id with me. I would like to know the correcponding procedure/query associated with that transaction id.
Is it really possible to find out old transaction details from any view?

About the pricing procedure of purchasing order

Hello friends,
can anyone tell me about the pricing procedure,conditions & texation of Purchase order?
and hoew to maintain all those term in Customisation?

The Basic thing is Condition Technique. In which there are
1. Access Sequence 2. Condition Record 3. Condition Type 4. Condition Table.
A Access Sequence access a Condition Record of a Condition Type in a Condition Table is a Condition Technique.This is a simple logic
Here the Condition Type is very important like PB00, PBXX,RA01 etc.
In the background every Condition Type has its own defition means the purpose of the Condition Type like, is it for Pricing or Percentage, Quntity base, Accrual Feilds etc is to be defined to work this functions. Normally we use the existing ones without any risk. But some cases, we have to Create a New Condition Types as per the organisation requirement.
The Pricing Schema is useful to minimise condition types while mention prices for Vendor on the basis of Pricing Schema which we defined according to organisation requirement.
The Pricing Schema means the calculations procedure of Condition Type.
Ex. RA01 - Discoount % is caclulated on PB00 - Gross Price means
RA01 is based on PB00 like that we have to define in the Pricing Schema
which makes easy to use in real time.
Here PB00 has the Access Sequence - 0002.
But RA01 does not have the Access Sequence.Why because it is a dependent on PB00. But both are Condition Types.
In the system, by default some standard Scheme will be there at Vendor Schema Group in the Vendor Master Screen means the standard one is assigned which is very lengthy which may fullfil our requirement. But some cases which may not fullfil our requirement, in such we have to define.
For the configuration, I may not able to explain properly through here but will give some idea.
Configuration: SPRO - IMG - Material Management - Purchasing - Conditions - Define Price Deternmination Process:
1. Define Access Sequence
2. Define Condition Type
3. Defince Calculation Schema:- Here you have to define the Schema - Define Schema group
1. Define Schema Group vendor
2. Define Pricing Schema group
3. Schema group for Purchase Organisation
4. Assign Schema group to Purchase Organisation - Define Schema determination
1.define calculation schema for Standard purchase organisation
After completion of the Schema Group, we have to assign it to Vendors.
Then whenever we use any transaction with this Vendor, the concerned Schema will work as configured by us.
The Pricing in MM is vast because each Condition have its own importance and each Access Sequence have its own importance. So you need not bother about this. First you learn how to define the Calculation Schema through the above.

How to go about the assessment of an essbase implementation

Hi ,
Can anybody guide me as in what should be the process flow of assessing an essbase implementation ???
I have done essbase implementations but never went about assessing an implementation.
Kindly help .
Regards,
Saurav Sarkar

I suppose it depends on what you mean by assessment, but I would be interested in things like:
Are the numbers right (you would be unpleasantly surprised)?
Does the organization buy into the database?
Is the business owner satisfied with the application?
Are the people who use the app satisfied?
Is the application a black box, put in by a consultant, or are all processes documented and understood by all?
What about the business processes that drive this?
How does the application fit into the customer's overall BI strategy?
Does the application meet its stated goals? I've got that back to front because the very first thing I would want to know is: what are the application's goals?
Is the process efficient? This is a multi part question as efficiency can mean:
Speed (is it fast enough? Calcs? Data loads? Dimension loads? Retrieves?)
Server resource consumption
How many people does it take to support the application? (I have seen the gamut: 1 superstar supporting everything, The Three Stooges barely supporting one)
Is the application flexible, data driven, and fully automated? If it isn't, how much effort goes into keeping the thing running?
Does it fit into the organization's future technological and organizational plans or is it a relic/band aid/unwanted step child?
Does it conform to the organization's IT standards (as far as Essbase can conform)?
Does it conform to the organization's audit team for security, access, etc.? Yeah, I know, they should have told the business all of that but again you would be surprised how if it ain't SQL, some auditors can't wrap their heads round it.
I guess that would be a start.
Of course the biggest single thing, and sometimes a very hard thing to get out of a customer, is, "Why are you now asking for an assessment?" Something is driving the expense (even if it's internally done, it isn't going to be without cost). Is it risk management? Dissatisfaction? Politics? Technology review? Performance (so likely dissatisfaction)? Once you know that, the rest of the questions will have the right perspective.
Just my 2¢.

hi Elistariel -
With no texting plan, it is 25 cents per picture message. The LG VX5500 (same phone my daughter has) does not use a memory card, so you can try two different programs on your computer (both free) and see if either one will get the pics off and saved on your computer; from there you can upload to your online album without a per picture charge.
You can try Verizon's VCast media manager - download and install it on your computer, then use the USB cable to link the phone to the computer and transfer the pics with VCast.
Here's a link
A third party program called BitPim will also work, but it's more technical and does a lot more than just transfer your media. It can also brick your phone if you don't know what you are doing, so it's "use at your own risk", as Verizon won't cover any losses due to using BitPim. It does work though--I have used it, very cautiously!

Can any one explain about the SAP Testing process in Implementation Project

Can any one explain about the SAP Testing process to be carried out by BW Consultant in an Implementation Project which is in Testing Phase..

hi bharat,
Two types of testing is possible in bw
unit testing
integration testing
Integration testing - It is the phase of software testing in which individual software modules are combined and tested as a group. It follows unit testing and precedes system testing.
Integration testing takes as its input modules that have been checked out by unit testing, groups them in larger aggregates, applies tests defined in an Integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing.
Unit testing - One part or the whole part of transfer rules , update rules, etc..
Integration testing - The whole data flow cycle to be tested

About the implementation of HashSet.add( ) method

Hi guys,
recently, I read the source code of HashSet, about the code of method of add():
public boolean add(E e) {
return map.put(e, PRESENT)==null;
I wonder why we need put 'PRESENT' to the value ? why not we put NULL to the value , like this:
return map.put(e, NULL)==null;
Please tell me the truth, thx a lot.

Please tell me the truth, thx a lot.As I recall, A HashSet<K> is actually backed by a HashMap<K, Boolean>, the Boolean being set to Boolean.TRUE Nope. <K, Object>
(and I suspect you'll find that PRESENT == Boolean.TRUE) for all entries.Nope:
private static final Object PRESENT = new Object();
- and furthermore is guaranteed to return null if the key didn't originally existAs EJP (and somebody else, I believe) pointed out, this is probably the heart of the reason to use an Object instead of null for the value.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.
In particular, I am analyzing the example "Even Angle Reference Signal Processing (Digital Tacho, DAQmx).vi", whose documentation I am reproducing in the following:
DESCRIPTIONS:
This VI demonstrates how to extract even angle reference signals and remove the slow-roll errors. It uses DAQmx VIs to acquire sound or vibration signals and a digital tachometer signal. This VI includes a two-step process: acquire data at low rotational speed to extract even angle reference; use the even angle reference to remove the errors in the vibration signal acquired at normal operation.
INSTRUCTIONS:
1. Run the VI.
2. On the DAQ Configurations tab, specify the sample rate, samples per channel, device and channel configurations, and tachometer channel information.
NOTE: You need to use DSA PXI-447x/PXI-446x and PXI TIO device in a PXI chassis to run this example. The DSA device must be in slot 2 of the PXI chassis.
3. Switch to Extract Even Angle Reference tab. Specify the number of samples to acquire and the # of revs in reference which determines the number of samples in even angle reference. Click Start to take a one-shot data acquisition of the vibration and tachometer signals. After the acquisition, you can see the extracted even angle references in Even Angle Reference.
4. Switch to the Remove Slow-roll Errors tab. Click Start to acquire data continuously and view the compensate results. Click Stop in this tab to stop the acquisition.
ORDER ANALYSIS VIs USED IN THIS EXAMPLE:
1. SVL Scale Voltage to EU.vi
2. OAT Digital Tacho Process.vi
3. OAT Get Even Angle Reference.vi
4. OAT Convert to Even Angle Signal.vi
5. OAT Compensate Even Angle Signal.vi
My question is: How is the synchronization produced at the time of the compensation ? How is it possible to eliminate the errors in a synchronized fashion with respect to the surface of the shaft bearing in mind that I am acquired data at a low rotation speed in order to get the "even angle reference" and then I use it to remove the errors in the vibration signal acquired at normal operation. In this application both operations are made in different acquisitions, therefore the reference of the correction signal is lost. Is it simply compensated without synchronizing ?
Our application is based on FPGA and we need to clarity those aspects before implementing the procedure.
Solved!

The question about the HA installation on ECC6.0

Hi Experts,
We are about to implement a project with HA environment on the ECC6.0 in the near future, which is just about the ABAP stack. After reading the Installating Guide, I stil have several questions related to the procedures of HA installation.
In the guide document, I got the following steps to process for realizing the HA of ECC6.0:
1. Run SAPinst to install the central services instance (ASCS) using the virtual host name on the primary cluster node, host A.
2. Prepare the standby node, host B, making sure that it meets the hardware and software requirements and it has all the necessary file systems, mount points, and (if required) Network File System (NFS), as described in Preparing for Switchover .
3. Set up the user environment on the standby node, host B. For more information, see Creating Operating System Users and Groups Manually. Make sure thatyou use the same user and group IDs as on the primary node. Create the home directories of users and copy all files from the home directory of the primary node.
4. Configure the switchover software and test that switchover functions correctly.
5. Install the database instance on the primary node, host A.
6. Install the central instance with SAPinst on the primary node, host A.
7.If required, install additional dialog instances with SAPinst to replicate the SAP system services that are not a SPOF. These nodes do not need to be part of the cluster.
My Question is that does standby node(host B in above context) need to install the ASCS, database instance and Central Instance?
If host B does not need to install the database instance, how about the whole system would be when the primary cluster node (Host A in above context) totally crash, such as power failure.

Hi Rong,
I would try to explain it in simple words...
My Question is that does standby node(host B in above context) need to install the ASCS,
database instance and Central Instance?
If host B does not need to install the database instance, how about the whole system would be when
the primary cluster node (Host A in above context) totally crash, such as power failure.
1. You don't need to install ASCS on Node B. You are installing it using a VIRTUAL HOSTNAME which represent cluster not individual node. VIRTUAL HOSTNAME is assigned to cluster package, so whichever Node is the owner of the package, will have the VIRTUAL HOSTNAME. (it will switch with cluster switchover)
2. It is actually a cluster package configuration magic. When Node A is active, cluster package owner is Node A. So all mount points (which is on SAN disk) is mounted on Node A. When you switchover the cluster, those packages will be mounted on Node B.
Some time single cluster package is used (which includes mount points for SAP instance + Database directories). You can also use 2 cluster package seperating SAP and Database directory structure.
Only OS related directories should be on servers local disk. All other application related mount points should be on SAN disk which is configured in "Cluster Package". (For example /sapmnt, /usr/sap, /oracle etc.)
You only need identical users and their enviornment settings on both Nodes.
In simple words, When primary node fails or crashed only users and thier enviornment setting will be lost. On second node, because of identical users and their profiles, same settings will be available to bring up the SAP system. Your all SAP and Database data is intact as it is on SAN Disk.
I hope, your confusion is cleared now...
Regards.
