BI-Java SP Level

Hi,
We have installed a BI-Portal 7.02 Sp03 and BW ABAP Stack 7.02 SP6
Does the java stack and abap stack still has to be kept at service SP level for 7.0 Ehp 2?

Hi,
Let me phrase your question- whether BI Java and BI ABAP stack level should be same ? As such it is not mandatory to have both on same stack level but it is always good to have both on the same stack.
Thanks
Sunny

JAVA PATCH LEVEL

Hi Experts,
I need small information on JAVA Patch level.
Presently we are on Patch level 15 in portal system and latest patch available in market place is 19.
Please guide me which patch level can i go and apply.
Regards
Jan

The best practice is to go with one step lesser than the highest patch available, because to get the fiexes to the problems with the highest patch will take some time and the 18 patch should have got the fixes by the time highest patch is released. and also you might get the possible issue with the patch 18 from the people who already adopted it or from the market place (you can get the report on impacts ) before proceeding to apply. The other point you need to consider is the patch 19 functionality and its immediate applicability as per your scenario.
Thank you,
Shyam

Redundancy at Java application level

Dear All,
Just wanted to know that how can we implement redundancy at Java application level in case of one database gets failed?
Please let me know for the same
Waiting for the reply
Regards
Jignesh

If you have a read-only database (you only do selects from it), simply retry the operation in another database if the first one fails. You could do a minimal select first to check if the db responds. E.g. in Oracle the idiom is "select sysdate from dual", in Postgres you can do "select 1", etc. But the server could fail between the test select and the real select, so you need to retry anyway, so the test select is redundant.
Perhaps retry, sleep a while, retry again, sleep, and after a few rounds give up. This gets around short network breaks, but doesn't busy loop forever if the program has a bug and the SQL statement is broken.
If you have a database where you also do inserts and updates, a backup database becomes ...problematic. If one server fails, and you start updating the other, you now have two conflicting data sets. Perhaps this could work if you have some kind of an append-only database - you add rows, like some kind of event logging; then you can merge the two data sets later. This gets somewhat specialized.
In the general case redundancy needs to be implemented as clustering at the db server level, not at the application level.

Abap and java patch level

Hi,
I have a portal installed on a standalone java based on sp13. I also have a backend ECC5.0 on a web as abap (sp9). If I want to connect the portal to the backend ecc, do I need to upgrade the abap to the same patch level as the standalone java (ie. sp13).
Also, I have installed the portal via rapid installer, which has also created a new sld for me. If I want to add the abap as a new technical system in the sld, is it required that both the java (of which the sld is based) and the abap be of the same patch level? thanks!

Hi,
If you want to connect to the backend system , both the Portal and ECC (Back end System ) need not be of the same pacth level. And you can also add the techincal system in SLD of diffrent pacth levels.
Thanks,
Tanuj

How to extract Java Annotaiton level

hi :
I am trying to extract annotation from a piece of code, but i also need to "descript " the output in RSF.
for example :
############ org.jboss.tutorial.stateful.bean.ShoppingCart.java #############
Annotation :15 : javax.ejb.Remote : {} : ShoppingCart
Annotation :21 : javax.ejb.Remove : {} : checkout
what meant to be in the {} is the level of the annotation been in
this is what i am trying to acheive:
############ org.jboss.tutorial.stateful.bean.ShoppingCart.java #############
Annotation :15 : javax.ejb.Remote : {InterfaceDeclaration} : ShoppingCart
Annotation :21 : javax.ejb.Remove : {MethodDeclaration} : checkout
how can i get the "annotation level" ( if that is the correct terminology for it) ??? eg, interfaceDeclaration, Methoddeclaration.. FieldDeclaration ???
Here is the piece of code that i used to print the above without the level detail
public void visitDeclaration(Declaration d){
for (AnnotationMirror d1: d.getAnnotationMirrors()){
System.out.println("Annotation :" + d.getPosition().line() + " : " + d1.getAnnotationType() +
" : " + d1.getElementValues()+ " : " + d.getSimpleName());
thanks in advance for any help

SAP BO Report Scheduling and Save as report using Java SDK

Hi All,
We have a java product which is integrated with SAP BO using Java SDK and we have certain java screen through which we select report prompt values and webi report gets run.
Now we want to give a functionality to save report to BO repository.
When user select certain check box from java screen a separate copy of the webi report should get saved under default folder on BO repository.
Also, we want user to choose the scheduling option from java screen only (and not the one which we use from BI Launchpad) due to certain access restriction. User does not have access to BI Launchpad. Only he can run report by selecting values through Java screen.
If i need to create a separate screen for scheduling as well as saving webi report then also i am ok with it.
P.S. i guess we need to work on Java SDK level. But could somebody please help me with the right direction?
Let me know in case requirement is not clear.

Hi Ketan,
As you are on version BI 4.0 SP5 and would be migrating to BI 4.1, the best SDKs to use would be the Restful Webservices SDKs.
You have the options to schedule a webi report with prompts as well as the save feature which you require.
Please refer to the webi restful guides avialble at
For BI 4.0 SP5

What are the pros and cons of installing java+abap stack for portal?

Hi all,
1.What are the pros and cons of installing java+abap stack for portal?
2.what effect it does on the ume options to be choosen??
3.for the purpose of integration of r3,bw and crm on portal and crm 4.0 60.2.3 business package which option of stack(java or abap or both)will be good option and which ume option while installation should be choosen?
regards
Rajendra

Hi Rajendra,
The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
In a nutshell:
ABAP+JAVA
Pros
- Decrease # of servers required to administer the portal
- Less costly
Cons
- Upgrades could be dependent on ABAP and Java release level
- Additional load on the server due to ABAP stack
- Limited scalability
JAVA and ABAP on separate server
Pros
- Improved performance
- Allows each system to be single-use purpose therefore downtime does not affect other components
- More scalable
Cons
- Adds complexity to landscape
- Additional costs

Thomas Pham

Scheduling in Real-Time Java

Hello,
I have some questions concerning how scheduling in fact is intended to be performed in a RTSJ based Real-Time Java System.
As far as I understood, RTSJ requires pre-emptive priority-based dispatching of Schedulable objects.
This means that the execution eligibility of a schedulable entity is mainly its priority.
That causality is reflected within the specification with the (one-and-only specified) PriorityScheduler, which is the base scheduler for actual Real-Time Java applications.
Furthermore, there is a notion of extensibility of that PriorityScheduler described by RTSJ,
in order to provide further scheduling mechanims and feasibility analysis algorithms (please correct me if there are any wrong assumptions).
This is the point, where everything becomes really weird to me ...
As far as I could investigate, in most RTSJ implementations based on a POSIX compliant system underneath (like Java RTS does on RTLinux or Solaris)
each (Realtime)JavaThread is mapped 1-to-1 to a light-weight process on the operating system level (e.g. a pthread).
So far, we have no "green threads" within the JVM, but real LWPs scheduled by the OS.
The difference between "normal" and "real-time" threads lies in the scheduling policy used for that mapping.
While normal Java threads probably map to SCHED_RR or SCHED_OTHER, real-time threads are scheduled by the OS via the SCHED_FIFO policy in order to achieve a better real-time predictability.
However, the OS's scheduling mechanisms automatically make decisions about the right positioning of a LWP within an appropriate run-queue, due to thread's preemption, blocking or release (even dynamic priority changes) activities and its scheduling policy.
That's exactly why I ask myself, what is the need of a Scheduler representation within a JVM?
Furthermore, how a Scheduler extension is able to incorporate with the threading model and the underlying scheduling mechanisms of the OS?
One point could be a situation where a real-time JVM runs directly on top of the bare hardware and has to perform scheduling decisions on its own.
The Scheduler API could then be understood as an extension mechanism of a kind of JVM-intern scheduler (e.g. the PriorityScheduler), thereby allowing scheduling decisions to be made even in user defined Scheduler implementations.
A similar use case for an OS-based scenario could be if a JVM is intended to pass scheduling/threading routines of the underlying OS (eg. a part of the POSIX API)
up to the Java application level in order to provide the opportunity for a kind of application defined scheduling (like e.g. in the MaRTE OS).
Unfortunatelly, after introspecting the RTSJ API, both conclusions seem to me to be wrong.
So far, Java RTS seems not to provide any mechanism for reaction on scheduling events/decisions, neither intra-JVM nor from an underlying OS outside of the JVM.
Furthermore, there is no notion for incorporation with the base PriorityScheduler for making extended scheduling decisions.
I hope this post could bring me more light into the scheduling idea behind Real-Time Java systems as intnded by the RTSJ.
Sincerely,
Vladimir

Vladimir.Nikolov wrote:
That means, that a scheduling policy different to PriorityScheduler can only be assigned to a Schedulable object if it is supported by the OS and the JVM?Well it has to be supported by that implementation of the RTSJ. Howe that is done - ie whether it requires OS support - depends on that VM, the OS and the actual scheduling policy.
It also seems that at the current state of the art the PriorityScheduler representative within the JVM is intended only for manipulating a feasibility set of Schedulable objects (supporting online feasibility analysis)?
However, since user-defined scheduling is not intended by the specification, applications have to rely on the feasibility analysis based on the underlying/supported scheduling mechanisms.
Thus, in the current Java RTS implementation this would be the "default" feasibility mechanism based on the PriorityScheduler.
Unfortunatelly I can not figure out the need of maintaining a feasibility set, since feasibility, as specified for the PriorityScheduler, is a simple asumption that we have "an adequatly fast machine to handle the periodic and sporadic load"?
I actually assumed that feasibility analysis performs real cost budgeting taking into account deadlines and so on, but it seems to be specified simply to make a negative statement always when aperiodic tasks are involved ?The RTSJ scheduling framework provides support for feasibility analysis by defining the admission control methods eg setXXXIfFeasible. However the RTSJ does not, and can not, mandate any non-trivial feasibility algorithm because in simple terms no such general algorithms exist. There are some static feasibility tests in the literature and you could apply those offline to your application (assuming you can find the values of all the "magic" numbers in such formulae - which is generally not the case). At present the RTSJ doesn't support even these simple feasibility tests because blocking-time is not recorded in the release parameters - something being addressed in RTSJ 1.1. In any case unless there is a pluggable framework for feasibility tests it would be a waste of time for VMs to implement them given they can (more) easily be done offline using other tools.
Only dynamic admission control is really of interest and as far as I am aware no such general dynamic admission control policies exist (anything you find in the literature is very context specific). So it is left up to an implementation as to whether they try and define dynamic admission control algorithms - and so far none have because they don't have one.
In "Getting More Flexible Scheduling in the RTSJ" Wellings and Zerzelidis propose some (more or less) "minor" extensions to the RTSJ API in order to enable hierarchical scheduling within the fixed priority framework.
Since Andy Wellings is a member of the RTSJ Technical Interpretation Committee, is there any attempt to evolve the specification in a similar direction as described above, in order to support more flexible scheduling mechanisms and feasibility analysis?If there is ever a RTSJ 2.0 then more sophisticated scheduling support is one of the items on the wishlist. But there's no guarantee there ever will be a RTSJ 2.0

"Class Formatting Error" in a java applet? (Solved)

(This problem is completely my fault and it would be hard to provide enough information to request and answer. Disregard this message.)
I've been developing a java applet to go on my website, but when running it tosses a "java.lang.ClassFormatError: rendering/ImageObserverClass" to the console. When I looked into the code I thought of java compliance levels. (Earlier I had to set Eclipse to a higher compliance level to make it accept new ArrayList<Renderable>();)
Is this not my problem? In my html code I have the following:
<applet
code="main/GalacticConflict.class"
codebase="code/"
width="640" height="480">
</applet>In Eclipse the program compiles and runs fine, so it most likely is a deeper issue. Thanks for any help!
EDIT:
Heh, that was stupid of me.... Just decided to try removing the <Renderable> from there, but it still doesn't work. The line number the console refers to is commented code, making it even more strange. If you have insight, feel free to post it here, but I'm going to make sure my new code is even being passed to my server properly.

Can Java do this

Hi,
I want to really learn Java after just taking classes to this point. I have a task I need to do, but cannot figure IF I can do it in Java, let alone how.
I have about 40 tools on my SGI. They are written in Fortran, C, or a commbination of both. Their code varies from a few lines to 200 or so source files. The machine is networked to other SGIs and Suns, but has no internet connections. My manager wants a top level GUI written to access these tools and to provide information about them.
Can this be done in Java without rewriting all of the tools?
I see that I need to be able to either:
1) Spawn a process (i.e. tell the system to run a given tool) from my Java top level GUI or
2) Write a small java interface for each tool and be able to compile that Java with the C or Fortran code.
Can you do this in Java? If so can someone suggest a book or website to send me in the right direction?
Thank you

As far as number two goes, that sounds like a real mess.

500   Internal Server Error : java.lang.NoClassDefFoundError in XI - SLD

Hi Sridhar,
Thanks a lot for your reply.
I can launch the transaction SXMB_IFR. It works fine. I got the XI frontend with Exchange Infrastructure Tools.
But when I click on the SLD I am getting this error.
I have also tried to open the http://<SLDserver>:<port>/sld link. But this is also giving me the same error.
I have checked the SLDCHECK transaction.
I am copy/pasting some part of the Check result for reference.
""Use transaction SLDAPICUST if you wish to maintain the SLD server access data

I have checked the following thread

But the solution provided in the thread "configure the hostname without any domain with transaction SLDAPICUST" doen not work.
By the way how to check whether SLD is running or not.
Thanks in advance and warm regards

BI Java landscape question

Hello,
In a small organization with little traffic is it possible to use one BI Java system to connect two enterprise portals (Dev + Prod) from one side and two BW 7 abap systems from the other side (Dev +Prod) or must I have a seperate BI Java for DEV and Prod
Thanks
Boaz

Hi Hector,
We were in the same situation few months back. We felt that the better option is to have separate Java stack and portal for BI. The major factor being that if you are using your EP as the portal for BW, there is a dependency of support packs and java patch levels. So, it is better that you keep these 2 separate. The conception that FPN configuration is difficult is wrong. We have successfully implemented FPN without much difficulty. Hope his helps.
Thanks and Regards

How to write a browser independent code in java?

Hi ,
Should I use swing code to achieve browser independency ? or will HTML help in a better way?
thnx and rgds hs

It's one of those Microsoft vs. Sun things. Microsoft hasn't implemented java swing, instead they have their own package called AFC, which only exists on internet explorer (and which I found it next to impossible to get documentation for).
So you are stuck with the really fairly crappy java.awt level classes.
