What is the cpu architeture of solaris version of BPEL bundle, x86 or SPARC

Hello,
I'd like to know what is the cpu architeture of solaris version of BPEL bundle, x86 or SPARC located here: http://download.oracle.com/otn/solaris/ias/1012/as_sun_bpel_101200.cpio
The file is more than 400Mb in size, so I need to know before downloading.
Thanks.

hi,
are there any plans to release it for x86 (32 bit) platform. I'm also interested in testing beta versions of oracle software (specifically bpel, jdeveloper) on solaris 10 x86 platform, is there any beta CD available for these purposes?
thanks.

TCP connection for DHCP failover frequently are broken in Solaris 10

Hi
We have two dhcp servers which are installed in Solaris 10 and set to a failover pair. Currently, we can find that tcp connection for dhcp failover protocol are frequently broken. It looks like that primary dhcp server initiatively send FIN message to secondary one but in general, this tcp connection should always keep alive. On the other hand, the tcp connection can not completely be closed right now which FIN_WAIT_2 status in Primary one and CLOSE_WAIT status in secondary would last for a long time.
Will Solaris 10 cause this fault? Is it a known bug in OS?

Can anyone kindly explain what mutative triggers are in Oracle?

hi
Can anyone kindly explain what mutative triggers are in Oracle with example?
what is frag in oracle?

Oracle raises the mutating table error to protect you from building in-deterministic software.
Let’s explain that with a very simple example. Here’s a simple EMP-table:
ENAME      SAL
======     ====
SMITH      6000
JONES      4000Let’s suppose you have a business rule that dictates that the average salary is not allowed to exceed 5000. Which is true for above EMP-table (avg. SAL is exactly 5000).
And you have (erroneously) built after-row triggers (insert and update) to verify this business rule. In your row trigger you compute the average salary, check it’s value and if it’s more than 5000 you raise an application error.
Now you issue following DML-statement, to increase the salary of employees earning less than the average salary, and to decrease the salary of employees earning more than the average salary.
Update EMP
Set SAL = SAL + ((select avg(SAL) from EMP) – SAL)/2;The end result of this update is:
ENAME      SAL
======     ====
SMITH      5500
JONES      4500Note that the business rule is still OK: the average salary still doesn’t exceed 5000. But what happens inside your row-trigger, that has a query on the EMP-table?
Let’s assume the rows are changed in the order I displayed them above. The first time your row trigger fires it sees this table:
ENAME      SAL
======     ====
SMITH      5500
JONES      4000The row trigger computes the average and sees that it is not more than 5000, so it does not raise the application error. The second time your row trigger fires it sees the end result.
ENAME      SAL
======     ====
SMITH      5500
JONES      4500For which we already concluded that the row-trigger will not raise the application error.
But what happens if Oracle in it’s infinite wisdom decides to process the rows in the other order? The first time your row trigger executes it sees this table:
ENAME      SAL
======     ====
SMITH      6000
JONES      4500And now the row-trigger concludes that the average salary exceeds 5000 and your code raises the application error.
Presto. You have just implemented indeterministic software. Sometimes it will work, and sometimes it will not work.
Why? Because you are seeing an intermediate snapshot of the EMP-table, that you really should not be seeing (that is: querying).
This is why Oracle prevents you from querying the table that is currently being mutated inside row-triggers (i.e. DML is executed against it).
It’s just to protect you against yourself.
(PS1. Note that this issue doesn't happen inside statement-triggers)
(PS2. This also shows that mutating table error is really only relevant when DML-statements affect more that one row.)

What is menu area? can we create a menu exit with tht?

Hi experts,
what is menu area? can we create a menu exit with tht? is areamenu(se43n) diff frm menu exit?

Hi
Menu Exits
Menu exits add items to the pull down menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.
Menu exits allow you to add your own functionallity to menus. Menu exits are implemented by SAP, and are reserved menu entries in the GUI interface. The developer can add his/her own text and logic for the menu.
Function codes for menu exits all start with "+"
Example
We want to create a new menu item in the Office menu. The text for the menu should be "Run ZTEST", and the menu will
run report ZTEST.
Goto transaction SE43 Area Menu Maintenance
In Area Menu Paramenter type 'S000' (S triple Zero)
Select Change and ignore all the warning screens
Expand the office menu. In the buttom of the office tree you will find a menu named "Customer function"
Double click on the text. In the pop-up screen change the text to "Run ZTEST". Note that the trsnaction code is +C01
Goto transaction SE93 and create transaction +C01 that calls report ZTEST.
Now you will se the menu displayed in the office tree. If you delete transaction +C01 again, the new menu will dissapear.
There are 'only' 177 Menu exits in standard - I couldn't see the right one, too.
But you could search the implemented exits, this should be only a small number. Go to transaction CMOD, enter * and F4, information system (F5), show all selections (Shift+F7) and then you can restrict to search only menu exits.
Of course there is the possibility, that these are added in a different way...
... at least you can be sure, if it's a normal menu exit.

Re: doubt on user exits
user exits and Badis
User exits is the enhancements provided by SAP
You can use them in transactions. Each transaction will have user exits.
If you want to use your own requirements by making your coding while the transaction is run you can use user exits.
For example if you want to run the MRP in MD02 specific to MRP controller you can user exit.
Please also refer the document below.
USEREXIT
Userxits allow us to add our own functionality to SAP standard program
without modifying it . These are implemented in the form of subroutines and hence are also known as FORM EXITs. The userexits are generally collected in includes and attached to the standard program by the SAP.
All Userexits start with the word USEREXIT_...
FORM USEREXIT_..
z..
ENDFORM.
The problem lies in finding the correct userexit and how to find it if one exists for the purpose. Once the correct userexit is found the necessary customer code is inserted in the customer include starting with the z.. in the form routine.
e.g. USEREXIT_SAVE_DOCUMENT_PREPARE
Certain application like SD still provide this form of enhancement using userexit but this practice is no longer being followed for newer extensions instead they are using EXITs which come bundeled in enhancement packages . Neverthiless existing USEREXITS will be supported by SAP an all the newer versions of SAP.
HOW TO FIND USEREXITS
Userexits can be found in number of ways:
1) To find userexits in SD module , goto object navigator(SE80) and select
development class from the list and enter VMOD in it. All of the userexits in SD are contained in the development class VMOD. Press enter and you will find all the includes which contain userexits in SD for different functions like PRICING, ORDER PROCESSING etc. Select the userexit according to the requirement and read the comment inserted in it and start coding .
Some examples of userexits in SD(SALES & DISTRIBUTION ) are:
1)ADDING OF NEW FIELDS IN PRICING
In Pricing in SD the fields on the basis of which pricing is done are derived from the FIELD CATALOG which is a structure KOMG .This structure is used to transfer transaction data to the pricing procedure in SD and is also known as communication structure.This structure KOMG consists of two tables KOMK for Header related fields and KOMP for item related fields. The fields which are not in either of the two tables KOMK and KOMP cannot be used in pricing .Sometimes a need arises when the pricing is to be based on some other criteria which is not present in the form of fields in either of the two tables. This problem can be solved by using USEREXITS which are provided for pricing in SD. Pricing takes place both when the SALES ORDER ( Transaction VA01) is created as well as when INVOICING ( Transaction VF01) is done.Hence SAP provides 2 userexits ,one for sales order processing which is
USEREXIT_PRICING_PREPARE_TKOMP or
USEREXIT_PRICING_PREPARE_TKOMK
Depending upon which table (KOMK or KOMP) the new fields were inserted we use either of the above two userexits.These userexits are found in include MV45AFZZ of the standard SAP sales order creation program SAPMV45A.
In the case of userexit which will be called when invoicing is done ,these
are provided in the include RY60AFZZ which is in the standard SAP program SAPMV45A. The name of the userexits are same. i.e
USEREXIT_PRICING_PREPARE_TKOMP or
USEREXIT_PRICING_PREPARE_TKOMK
These userexits are used for passing the data from the communication structure to the pricing procedure, for this we have to fill the newely created field in the communication structure KOMG for this we fill the code in the above userexit using the MOVE statement after the data that has to be passed is taken from the database table by using the SELECT statement. The actual structure which is visible in these userexits and which is to be filled for that particular field is TKOMP or TKOMK.
Before the coding for these userexits is done ,it is necessary to create a new field in either of the two tables KOMK or KOMP .For this purpose includes are provided in each of them .
To create the field in header data(KOMK) the include provided is KOMKAZ
and to create the field in item data(KOMP) the include provided is KOMPAZ.
One possible example for the need of creating new fields can be e.g. Frieght to be based upon transportation zone ,for this no field is available in field catalog and hence it can be created in KOMK and then above userexits can be used to fill the transportation data to it.
2)The other method of finding userexit is to find the word USEREXIT in the
associated program of the transaction for which we want to determine userexit using SE38.
3)The other method of finding userexits is to find the include in case of SD/MM applications where the userexits are located ,this can be found in the SAP reference IMG generally in the subfolder under SYSTEM MODIFICATION.
Some other examples of userexits in SD are:
USEREXIT_NUMBER_RANGE
This userexit is used to assign a different internal document number to the
sales order(VA01) when it is created depending on some criteria like a different SALES ORGANIZAION(VKORG) .
USEREXIT_SAVE_DOCUMENT_PREPARE
This userexit is used to insert the ABAP code which will be called when
the document (sales order VA01) is just about to be saved.This userexit is used generally for custom checks on different fields , to display some information before the order will be saved or for making changes to certain fields before the sales order will be saved.
Exits & Enhancements
There are mainly six types of EXITs in sap which have been collected in the form of enhancement packages and attached to standard code in SAP.
These are different from USEREXIT in the way that they are implemented
in the form of FUNCTIONs while in USEREXITS we use form routines for their implementation. These are also sometimes known as function exits .
These start from the word EXIT_ followed by the program name and then followed by a three digit number.
e.g. EXIT_SAPMV45A_002
This exit is found in SD in enhancement V45A0002.
TYPES OF EXITS
1)MENU EXITS
2)FUNCTION EXITS
3)TABLE EXITS
4)SCREEN EXITS
5)KEYWORD EXITS
6)FIELD EXITS
We use SAP transactions CMOD and SMOD to manage exits. Before implementing an exit , it is required to create the project by using CMOD
selecting the enhancement e.g. V45A0002 and selecting the component
(one which fulfills our need) i.e the exit which will be implemented in SMOD and after coding has been done the project has to be activated.
An exit can be coded only once.
FUNCTION EXITS
These are used to add functionality through ABAP code . These start from the word EXIT_programname_NNN ending in a 3 digit number. No access code is required to implement any tupe of exit including function exits.
The function exits are called from the standard SAP program in the form
of ABAP statement
CALL CUSTOMER-FUNCTION 'NNN'
This is in contrast to USEREXITs where PERFORM statement is used to call
the required userexit.
To implement the FUNCTION EXITs first of all the project is created and a suitable enhancement package is selected and from its compnents the function exit to be implemented is selected and on double clicking it the exit code will appear in ABAP EDITOR(se38) where a Z include will be found and the customer code should be entered in this include.
e.g.
ADDING A DEFAULT SOLD-TO-PARTY in Sales Order Creation
To show a default sold-to-party in this field when the user creates a sales order (VA01) we can use a function exit .This function exit is located in enhancement no V45A0002 . Before we can choose the exit we have to create a project in CMOD after that enter V45A0002 in the enhancement field and click on the components . In the components you will see the exit EXIT_SAPMV45A_002 . This exit is used for our purpose.
Double clicking on this exit will takes us to function builder (SE37) . This
function exit has one exporting parameters and two importing parameters, we are interested in exporting parameter which is E_KUNNR of type KNA1-KUNNR i.e if we move the desired customer name to this structure(E_KUNNR) it will be shown in the field as the default value when we create the sales order. This function also contains a customer include ZXVVA04 . This include will be used to write our custom code .
Double clicking on this include and it will prompt us that this include does not exists do you want to create this object ,select yes and the include will be created .In this include we can write our own code that will fill the field E_KUNNR.
e.g. E_KUNNR = 301.
Activate the include and Activate the project. Now when ever the SALES ORDER will be created , sold-to-party field will come up with a predefined customer .
FIELD EXITS
The field exits are managed,created,activated through program RSMODPRF. The field exit is associated with a data element existing in ABAP dictionary and hence to the screen field using that data element.
The format of field exit is :
FIELD_EXIT_dataelement_A-Z or 0-9
If a particular screen and program name is not specified than the field exit will effect all the screens containing that data element.
The function module associated with field exit shows two parameters
INPUT and OUTPUT. Input parameter contains the data passed to the field exit when the field exit was invoked by the R/3 , We can write our own code to change the output parameter depending upon our requirements.
Before the field exit can have any effect the system profile parameter
ABAP/FIELDEXIT in all the application servers should be set to YES
ABAP/FIELDEXIT = YES.

What Options I can implement for comunication PC ( lan ethernet) with SNA S

What Options I can implement for comunication PC ( lan ethernet) with SNA Server (Lan Token Ring) :
To see file
thanks you,
jj González

What version of SNA server are you using?
SNA server version 3 and higher support tn3270/tn3270e (for mainframe connectivity) and tn5250 (for as/400 connectivity) clients. The ms windoes telnet client does not support those protocols so you need a 3270 and/or 5250 emulator from another vendor, such as NetManage or Hummingbird.
This assumes that you have a routed network between your workstation and the sna server.
If your network is bridged, then you need to use an emulator that works with the native sna protocol, as the sna server supports that as well. The NetManage and Hummingbird emulators will work in this case too.
Try to use the tn3270/tn5250 as the first choice as it does not require a bridged backbone. SNA is not a routeable protcol by default.
Let me know if this helps.

Which classes are implemented ?

hi,
is there a possibility that a javacard does not implement all javacard api classes ?
if yes, then how can I know which classes are implemeneted, and which are not ?
Kuba

Sure that's possible.
An example is that there are different javacards. One that implements RSA and one that just implements DES. Not only that, but the vendors can determine what key strengths they want to implement as well.
Before you buy a kit find out by looking at the specs that detail what they are implementing.

What OS's are supported.

I am looking at 10G and its says release 2 supports the following operating systems
Oracle Enterprise Linux 5 (OEL5)
Oracle Enterprise Linux 4 (OEL4)
Red Hat Enterprise Linux 5 (RHEL5)
Red Hat Enterprise Linux 4 (RHEL4)
Red Hat Enterprise Linux 3 (RHEL3)
Novell SUSE Linux Enterprise Server 10 (SLES10)
Novell SUSE Linux Enterprise Server 9 (SLES9)
Asianux 2.0
Asianux 1.0
the question i have is does 10g support solaris ???
Also what OS's does 11G support ???
It doesnt seem to be much documentation on this !!!

First, just to help clear things a little bit, the way to ask is "what versions of Oracle are certified or supported on what operating systems".
Another words, Solaris doesn't support Oracle (any release).
Oracle software is certified and supported on the Solaris platform.
So, to answer your question:
Oracle 10g is supported on Solaris, but without looking it up, I can probably tell you that it is only supported (and certified) for Solaris 9 and 10.
There may be some backwards extended support for Solaris 8 (2.8), but Solaris 10 is probably the most common.
Again, Oracle 11 doesn't support any OS.
It is a matter of which operating system (and OS level) that Oracle software is certified to run on (and supported on).
Hope this helps...

How sessions are implemented on server

Hi All,
Can anyone please tell me how sessions are implemented on server like JRun, WebLogic, WebSphere or in general ?
Thanks & Regards,
Kumar.

A common way to implement sessions in web servers would be something along the lines of...:
1) When a browser accesses the webserver, the webserver sends a cookie with a session id to
the browser.
2) The webserver creates an instance of some proprietary class that implements the
javax.servlet.http.HttpSession interface (comes with J2EE)
3) The webserver stores the session instance in a java.util.Map instance using the session id as the key.
4) When the browser hits the web server again, the cookie containing the session id is also sent, and
the web server knows which session instance to use when processing this request.
5) If the browser doesn't have cookies enabled, URL rewriting can be used. URL rewriting means that
the webserver adds the session id as a parameter to every link in the web application. Thus, whenever
the browser accesses the server again, the session id will be part of the URL, and the web server will
know what session instance to use when processing the request.
6) The webserver has a thread checking the session instances regularly to see if they are still valid,
meaning if their timeout limit hasn't been passed since the last request. If a session has expired it will
be removed. If a browser accesses a server with an old session id, the server will send a new cookie
with a new session id to the browser.
7) If the web server is part of a cluster, the session instance must be stored in a central database so all
web servers can access it, or the session must be replicated from the current server to all other servers in the cluster, whenever the values in the session instance changes.
Though I'm not an expert on Java web servers, I believe the, or variations of the above of course, will be how it's done.
Hope this gives you an idea.

What is function area

hi expert
what is funtion area in wbs. can you give me some example?

Check details using F1 key - this is what you should get -
Functional Area
Structure criterion for an enterprise or government based on functional aspects.
Use for Cost-of-Sales Accounting
The functional area is required to create a profit and loss account in Financial Accounting using cost-of-sales accounting. The following are examples of structure criteria:
Manufacturing
Administration
Sales
Research and development
Use for Government
The functional area is needed for Funds Management to meet legal requirements for reporting with functional aspects. You can use the functional area to represent the global targets and goals (such as public safety or city development), in particular the expenses of your organization.
Further notes
Use in cost-of-sales accounting
See the documentation on Filling the Functional Area Field.
For comprehensive information on cost-of-sales accounting and on the functional area, see the SAP Library under Accounting -> Financial Accounting -> General Ledger -> Cost-of-Sales Accounting.
Use in government
For more information on the functional area, see the implementation Guide for Funds Management Government in the section Activate Account Assignment Elements.

I am trying to sync my 5th gen. Keep getting a message about items on my iPod not in my library. How do I find out what these items are?

I'm trying to sync my 5th gen iPod and I keep getting a message that there are items on my iPod that are not in my iTunes and they'll be deleted if I don't transfer them. How do I find out what these items are so I know if I want them or not? Also, I seem to have a fair amount of duplicates, one marked with the cloudn symbol and one not. Which one do I delete??

Go to your "Purchased" list. See:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
and look for items not on this computer.
