Hi All,
My team has to Install the Java 6.40 SP 19 WAS and have no clue how to do that. In market place what should be the point of start, we dont have much Idea.
I request you to kindly answer few of my questions. They are as follows.
1) We are using windows XP professional, in that case,from market place what should be components that we need to download for installing Java 6.40 SP 19.
2) What should be the steps that the team should take to install the WAS.
3) Once the WAS is installed we need to also install the Portal component for the same. In that case what should be the steps followed.
Please let me know if you need any additional information.

Query regarding Enterprise Link installation

Hi,
Request a clarification from this forum.
I am working on the Oracle BAM example provided in the paper "Enabling Real Time Operational Analytics: Integration between Oracle E-Business Suite 11.5.10 and Oracle BAM 10.1.2". In the section titled "Design Data Extraction and Consolidation Layer", there are certain steps to be performed from Design Studio.
My existing installation was done using the package "bam_windows_x86_101330.zip" (which is without Enterprise Link). Now can I download the "bam_with_el_windows_x86_101330.zip" and run the installation just to install the Enterprise Link component separately without disturbing the current Oracle BAM setup?
Thank you.

Balu

Query regarding java embedding activity in Oracle SOA Suite 11g

Hi,
Recently I've come across a scenario in my project. I've got a BPEL process with a java embedding activity. Now that java embedding activity calls a java class similar to the code below :-
>ArrayList<MyData> data=MSExcelParser.getData();
Now, after getting this data inside the java embedding, I need to populate a BPEL variable. The BPEL variable is based on an XSD element "BPELVariable" which looks something like the below snippet :-
><xsd:element name="BPELVariable" type="BPELVariableType"/>
> <xsd:complexType name="BPELVariableType">
> <xsd:sequence>
> <xsd:element name="MyData" type="MyDataType" maxouccurs="unbounded"/>
> </xsd:sequence>
></xsd:complexType>
So the BPEL variable that I want to populate can contain multiple "MyData" tags. Now my question is how can I populate the variable from my java embedding activity once I've got the list. Is it possible?
Thanks,
Rahul

I think we can exchange only data types, i dont see any data type which can hold the object types.
If you find anything better let us know.
Constructing string xml and converting to xml is best option i can think of.

Web AS-Java 640 Add-In installation for XI

HI Guys,
We have installed Web-As ABAP 640 on Windows 2003 and MSSQL 2000 SP3 server.
We have created named instance called "SAPDEV01\SAPXI".
While installing Web As-Java 640 as a Add-In we have encounted following error:
"SEVERE: couldn't connect to DB
java.sql.SQLException: [DataDirect][SQLServer JDBC Driver][SQLServer]Login failed for user 'SAPGXDDB'. Reason: Not associated with a trusted SQL Server connection.
We have checked the authentication mode of MSSQL server, it is "SQL server and Windows", still we are facing the problem.
Please give us solution ASAP.
Regards,
Atul

Specific Requirements
Take the following specific requirements of the new installation process into consideration:
- The previous SAPInst installation service Java Add-In in SAP ERP 6.0/SAP NetWeaver
7.0 was able to add Java usage types such as EPC, or EP, to existing ABAP-only
systems. This was possible only, if you added AS Java at the same time. The option of a
Java Add-In installation is not any longer available as of the enhancement package 4 for
SAP ERP 6.0. Thus, it is not any longer possible, for example, to add EPC and EP
together with AS Java to an ABAP-only system.
[SAP Enhancement Package 4 for SAP ERP 6.0|https://websmp201.sap-ag.de/~sapidb/011000358700000772192007E]
There are many links on SDN discussing ERP EHP 4 dual stack:

Hope this helps.

WAS JAVA 640 engine is giving performance problems.

Hi,
We are facing the performance issues in WAS java 640 SP19 engine. Pages are taking much time to load.
Kindly suggest if there anything do with jco connection parameter changes and recommended values. Is there any parametes to check at the backend system level.
WAS version: 640, SP19
OS : SUN 5.9
Oralce: 9.2.0.8
Thanks,
Hareesh

Hello Hareesh
You should find the root cause of your performance problem first.
Start with checking the server (cpu, memory, paging) and by checking if your portal runs on the recommended parameters (check oss notes).
A killer for portal performance is when you have a lot of paging going on, make sure the portal has enough extended memory available to avoid any paging.
If those don't give a result, you can still analyze garbage collection logs with third party tools.
Check if heapdumps are being generated and analyze them.
Once those checks are done, I would recommend installation of Sol Man Diagnostics + Wily Introscope so you get a better view on what is going on and troubleshoot further from there.
Kind regards
Tom

Any idea??
Thanks so much in advance!

Hi Sunny, hi Markus!
many thanks for your hints!
I've just solved the problem. The problem was, our Listener was not configured correctly.
I've adjusted the listener.ora, tnsnames.ora to the correct hostname - cause, we had a hostname-switch last month and I had forgotten to adapt the Listener...
now the Listener is running as well:

JAVA Stack installation's method for BI 7.0 (Netweaver 04s)

Hello!
We plan to upgrade our BW 3.5 (without java stack) to BI 7.0 which need a java stack installation.
In this case we have, first, to upgrade the abap stack and then we have to install the java stack .
There are 3 possibilities to install the java stack : as java-addin in the same database that the abap stack , or as the recommanded
SAP 'method i.e. a java installation with its own database , that means another instance , and I think a new license to buy.
The third method is a second server to support the java stack with its own database (separate instance).
I don't understand why the second and third methods are recommanded , rather than the first.
Is it related to the SAP Enterprise Portal ??; (we don't use it at the moment) , or for other reasons?? Thanks..

In the event of double-stack or shared installations, ABAP and JAVA compete for main memory and CPU resources. Since BI 7.0 is resource intensive, it is advisable to install AS-Java on a different machine.
Please refer to the following SAP Notes
1. 927530 - BI Java sizing
2. 917950 - SAP NetWeaver 2004s: Setting Up BEx Web

Query regarding updation thru a Procedure

Hi,I have a query regarding updation.
1.I invoke a procedure in Oracle called submit thru my Java application.
The submit procedure saves the XML data in the database
and displays this data in a Front End GUI.
2. Now,I make a change in my Java application by adding new elements to the same row.This row now contains additional XML elements.
I would like to display the new row with the new elements in the GUI.
What is a better option for doing the above?
1.Delete the row being shown,save the new row with the changes in the database,and re display it?
2.Or,Update the row dynamically and refresh?
Any suggestions
Thanks,

Thanks,If you delete (it seems to me yours this process is regular and frequent) and re insert the new updated one record then High water mark will cause to scan yours table which may cause to degrade the performance.AFAIK you should go with update.But hold down dont implement it as i suggested lets see what are others solution here which may be more precious then mine.

A query regarding synchronised functions, using shared object

Hi all.
I have this little query, regarding the functions that are synchronised, based on accessing the lock to the object, which is being used for synchronizing.
Ok, I will clear myself with the following example :
class First
int a;
static int b;
public void func_one()
synchronized((Integer) a)
{ // function logic
} // End of func_one
public void func_two()
synchronized((Integer) b)
{ / function logic
} // End of func_two
public static void func_three()
synchronized((Integer) a)
{ // function logic
} // End of func_three, WHICH IS ACTUALLY NOT ALLOWED,
// just written here for completeness.
public static void func_four()
synchronized((Integer) b)
{ / function logic
} // End of func_four
First obj1 = new First();
First obj2 = new First();
Note that the four functions are different on the following criteria :
a) Whether the function is static or non-static.
b) Whether the object on which synchronization is based is a static, or a non-static member of the class.
Now, first my-thoughts; kindly correct me if I am wrong :
a) In case 1, we have a non-static function, synchronized on a non-static object. Thus, effectively, there is no-synchronisation, since in case obj1 and obj2 happen to call the func_one at the same time, obj1 will obtain lock for obj1.a; and obj2 will obtain lock to obj2.a; and both can go inside the supposed-to-be-synchronized-function-but-actually-is-not merrily.
Kindly correct me I am wrong anywhere in the above.
b) In case 2, we have a non-static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a. However, since obj1.a and obj2.a are the same, thus we will indeed obtain sychronisation.
Kindly correct me I am wrong anywhere in the above.
c) In case 3, we have a static function , synchronized on a non-static object. However, Java does not allow functions of this type, so we may safely move forward.
d) In case 4, we have a static function, synchronized on a static object.
Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a. However, since obj1.a and obj2.a are the same, thus we will indeed obtain sychronisation. But we are only partly done for this case.
First, Kindly correct me I am wrong anywhere in the above.
Now, I have a query : what happens if the call is made in a classically static manner, i.e. using the statement "First.func_four;".
Another query : so far we have been assuming that the only objects contending for the synchronized function are obj1, and obj2, in a single thread. Now, consider this, suppose we have the same reference obj1, in two threads, and the call "obj1.func_four;" happens to occur at the same time from each of these threads. Thus, we have obj1 rying to obtain lock for obj1.a; and again obj1 trying to obtain lock for obj1.a, which are the same locks. So, if obj1.a of the first thread obtains the lock, then it will enter the function no-doubt, but the call from the second thread will also succeed. Thus, effectively, our synchronisation is broken.
Or am I being dumb ?
Looking forward to replies..
Ashutosh

a) In case 1, we have a non-static function, synchronized on a non-static object. Thus, effectively, there is no-synchronisationThere is no synchronization between distinct First objects, but that's what you specified. Apart from the coding bug noted below, there would be synchronization between different threads using the same instance of First.
b) In case 2, we have a non-static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a.obj1/2 don't call methods or try to obtain locks. The two different threads do that. And you mean First.b, not obj1.b and obj2.b, but see also below.
d) In case 4, we have a static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a.Again, obj1/2 don't call methods or try to obtain locks. The two different threads do that. And again, you mean First.b. obj1.b and obj2.b are the same as First.b. Does that make it clearer?
Now, I have a query : what happens if the call is made in a classically static manner, i.e. using the statement "First.func_four;".That's what happens in any case whether you write obj1.func_four(), obj2.func)four(), or First.func_four(). All these are identical when func_four(0 is static.
Now, consider this, suppose we have the same reference obj1, in two threads, and the call "obj1.func_four;" happens to occur at the same time from each of these threads. Thus, we have obj1 rying to obtain lock for obj1.aNo we don't, we have a thread trying to obtain the lock on First.b.
and again obj1 trying to obtain lock for obj1.aYou mean obj2 and First.b, but obj2 doesn't obtain the lock, the thread does.
which are the same locks. So, if obj1.a of the first thread obtains the lock, then it will enter the function no-doubt, but the call from the second thread will also succeed.Of course it won't. Your reasoning here makes zero sense..Once First.b is locked it is locked. End of story.
Thus, effectively, our synchronisation is broken.No it isn't. The second thread will wait on the same First.b object that the first thread has locked.
However in any case you have a much bigger problem here. You're autoboxing your local 'int' variable to a possibly brand-new Integer object every call, so there may be no synchronization at all.
You need:
Object a = new Object();
static Object b = new Object();

Publishing XI exposed webservices in the UDDI Server of SAP WAS JAVA 640

Hi Friends,
    I have a question regarding publishing a WSDL created via XI (Integration Directory) to a UDDI Server of SAP WAS JAVA 640. Can I publish the WSDL generated from XI in the UDDI Server provided as a part of SAP WAS 640 ? I know that the WSDL will be specific for a client( sender) but I feel that its better than emailing the WSDL to the client after generating it in the integration directory. Any relevant documents, links explaining how to do that will be appreciated.
    The above question was asked by Siva Maranani before. His question was as below .
"I know that whenever a webservice is developed using NDS it can be deployed in WebAs and the same can be registered in UDDI ( webAs acting as UDDI registry).
Now my requirement is to register a WSDL file (which describes) for an external webservice. Can WebAs be used as a UDDI registry..?
I like to know if this is possible or not..? if yes.. how..?"
Waiting for the reply...
Thanks & Regards,
Mathew

Hi Naveen,
           Thanks for the quick response. I tried the steps mentioned in the link.
1. Successfully created a new local UDDI registry in SAP WAS..
2. Assigned users etc.
The place I am getting stuck is..
"Make sure that the Web Service Definition has already been created and configured".
I have a WSDL document created via Define webservice in the XI integration directory.(We are successfully able to call the webservice using this WSDL via .net & xmlspy)
Where should I upload this WSDL ? so that the users will able to download/reference it w/out myself emailing to them.We dont/won't have NDS installed in our landscape.
I understand that whenever a webservice is developed using NDS it can be deployed in WebAs and the same can be registered in UDDI ( webAs acting as UDDI registry).
The requirement is to register a WSDL file generated via XI w/out using NDS.
Did you able to publish a WSDL file generated via XI in the local UDDI w/out using NDS ?
waiting for your reply
Thanks a lot,
Mathew

Query regarding using JNI in linux

Hi
I have a query regarding JNI.We have a situation in which
we have some c programmes and we want to call that c programme method in my java code. The problem is that in JNI the native code signature should match the signature of the method of the header file generated by javah. We donot want to change the signature of the native code since it is hard to debug.So please suggest me a way out that i can call the native method without changing the signature of the native code.Please if u could give me some few simple example
Thanking u

So please suggest me a way out that i can call the native method without changing the signature of the native code.You write a wrapper. Your java JNI class has methods. Those methods are written in C by you. Those methods are new code. Those methods call your existing C methods.
Please if u could give me some few simple example.http://java.sun.com/docs/books/tutorial/native1.1/index.html
