J2EE ClusterID of the executing node in program

Hello All,
Can anybody help me with sample code to find ClusterID of the J2EE server node on which the program is running.
Trying to make some sort of debugging code to generate an iView which will tell that which server user is attached to based on the ClusterID.
I guess this code may need to read J2EE core services or depend on JSESSIONID cookie.
Thanks In advance.

Ashutosh

Hello Seen,
Thanks for the reply and good to here from you after long time. We are live on EP6-SP2-Patch5.
You are right and we can use saplb_* to nevigate to a perticular node in NW and I will try to see if I can use that.
Currently my idea was to make a small component which on execution will give the server id on which it is getting executed. If user reports any problem I want to know which server he is working on.
Any other ides?
Best regards
Ashutosh

Table which stores the executed 'Z' programs

Hi All,
I want to know in which table the EXECUTED 'Z' programs will be stored.

Pavan, ABAP buffer PXA (Program Execution Area) Stores the compiled executable versions of ABAP programs (loads). The contents of this buffer are stored in tables D010L (ABAP loads), D010T (texts) and D010Y. And for reports D010S, probably Z's are stored in last one.

To update the Associate node from se38 program

Sasikumar S
Can anybody help me on that thanks in advance.

Hi Sasi,
According to what you have written above, You want to update a Z node under a root node.
But in the coding for association you have written a standard node.
Give the name of the Z interface which is created and in that you will have the 'Z' custom created node.
Try this.
ls_mod>-association = "Z Interface"=>SC_ASSOCIATION-"root_node"-znode.
Hope this helps you.

How can I execute an external program from within a button's event handler?

I am using Tomcat ApacheTomcat 6.0.16 with Netbeans 6.1 (with the latest JDK/J2EE)
I need to execute external programs from an event handler for a button on a JSF page (the program is compiled, and extremely fast compared both to plain java and especially stored procedures written in SQL).
I tried what I'd do in a standalone program (as shown in the appended code), but it didn't work. Instead I received text saying the program couldn't be found. This error message comes even if I try the Windows command "dir". I thought with 'dir' I'd at least get the contents of the current working directory. :-(
I can probably get by with cgi on Apache's httpd server (or, I understand tomcat supports cgi, but I have yet to get that to work either), but whatever I do I need to be able to do it from within the button's event handler. And if I resort to cgi, I must be able to maintain session jumping from one server to the other and back.
So, then, how can I do this?
Thanks
Ted
NB: The programs that I need to run do NOT take input from the user. Rather, my code in the web application processes user selections from selection controls, and a couple field controls, sanitizes the inoputs and places clean, safe data in a MySQL database, and then the external program I need to run gets safe data from the database, does some heavy duty number crunching, and puts the output data into the database. They are well insulated from mischeif.
NB: In the following array_function_test.pl was placed in the same folder as the web application's jsp pages, (and I'd tried WEB-INF - with the same result), and I DID see the file in the application's war file.
        try {
            java.lang.ProcessBuilder pn = new java.lang.ProcessBuilder("array_function_test.pl");
            //pn.directory(new java.io.File("K:\\work"));
            java.lang.Process pr = pn.start();
            java.io.BufferedInputStream bis = (java.io.BufferedInputStream)pr.getInputStream();
            String tmp = new String("");
            byte b[] = new byte[1000];
            int i = 0;
            while (i != -1) {
                bis.read(b);
                tmp += new String(b);
            getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + tmp);
        } catch (java.io.IOException ex) {
            getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + ex.getMessage());
        }

Hi Fonsi!
One way to execute an external program is to use the System Exec.vi. You find it in the functions pallet under Communication.

How can I hide the main front panel when I run from the executable?

Hopefully this is an easy question. I have an application where the front panel is not the main GUI and I would like to hide it when the program runs, but only when it runs from the executable. How can I do this?

NIquist wrote:
Yeah, don't do that. Executables built in LV require at least one front panel to be open. If it isn't, the run-time engine automatically closes the executable. I haven't checked recently, but I assume this is still the case.
Instead, you can set the FP state to minimized (as suggested earlier) or (better) to hidden.
P.S. one side point - the property and invoke nodes have a shortcut - if you use the Application or VI classes and don't connect a reference, they default to the current app or VI. That means you don't have to open the reference.

Using the Formula Node for PDA

I get a compile error when I use C code inside the formula node. Is it possible to use C Code inside the formula node for PDA applications? Do I have to include any file while building the executable for the PDA

Ok, I was able to successfully build an executable file without error. I attached the screen shots of your program in execution. Does this look like the desired result?
I'm confused as to why I can build and run the program on my machine. I have LabVIEW 7.0 and Windows XP. What version of Windows and LabVIEW are you using? Also, are you getting the error window when you try to build an executable or when you attempt to run the VIs within LabVIEW?

Open VI Reference Error in the executable version only

Hello folks! I am having a strange issue since I updated to Labview 2014: I have a vi that uses "Open VI Reference" in order to programmatically open the desired vi. It worked flawless also in the compiled version (.exe) of the program until yesterday, when i compiled it again for the first time since my update to Labview 2014. It compiles with no problem, but when i start the exe and load the first vi it already gives me an error "Built Application or Shared Library (DLL): Missing".
The point is that all the VIs that i want to open are inside an LLB that is supposed to be compiled inside the .exe: infact the path that i use to open is:
D:\LabVIEW Data\builds\Sequenzer\Sequenzer2.0.exe\com_lv_sequenzer\trunk\Sequenzer_Functions.llb\Seq_Connect_to_Database.vi
And i get error number 7:
Open VI Reference in Seq_Function_Interface.vi->Sequenzer_Main_2.0.vi<APPEND>
VI Path: <b>D:\LabVIEW Data\builds\Sequenzer\Sequenzer2.0.exe\com_lv_sequenzer\trunk\Sequenzer_Functions.llb\Seq_Connect_to_Database.vi</b>
Built Application or Shared Library (DLL): Make sure all dynamically loaded VIs were properly included in the build specification for the application or shared library.
LabVIEW Real-Time: VIs built into executables cannot be accessed through VI Server calls. Use Source Distributions to dynamically call VIs on Real-Time targets.
The vi Seq_Connect_to_Database.vi is included in my built (as you can see in the attached screenshot and as it has always been).
Do you have an idea of why it is not working anymore?
Thanks a lot in advance!

OK, here is where I am confused. You talk about including the llb in the build, but in the screen shot you show a bunch of individual VIs being included. Next, in source file settings where are you telling the app builder to store all those individual VIs? Because they are VIs LabVIEW will, by default, want to put them in the executable somewhere.

Error while executing HelloWorld.java program

Hi All,
I am trying to execute the samples(HelloWorld.java) program from Jdeveloper and provided the following details in runtime.defaults:
CONTENT_DB_URL
ADMIN_USER_NAME
ADMIN_USER_PASSWORD
however getting the following exception:
FdkException:
Error Code: ORACLE.FDK.UnexpectedError
Detailed Error Code: ORACLE.FDK.FeatureNotEnabled
Trace Id:

can any one please help me to resolve this issue.
Thanks
Krrish.

See the Cleartext Authentication note in the running_client_samples.html file of the CDB devkit.
The default configuration for an out-of-box Oracle Content DB installation allows Cleartext Authentication only if SSL has been enabled (and the Web Services connection string begins with https). See the authentication topic for details.
To allow Cleartext Authentication to take place over standard (non-SSL) HTTP, set the Oracle Content DB domain property IFS.DOMAIN.WS.CleartextAuthenticationRequiresHttps to false using Enterprise Manager (Application Server Control). See the Content DB Administration Guide for details.
If the domain property above is not modified to false and Cleartext Authentication is attempted using using standard HTTP, an FdkException will be thrown:
ORACLE.FDK.UnexpectedError : ORACLE.FDK.FeatureNotEnabled
cheers

Data processing in multiple caches in the same node

we are using a partitioned cache to load data ( multiple types of data) in multiple named caches. In one partition, we plan to have all related data and we have got this using key association.
Now I want to do processing with in that node and do some reconciliation of the data from various sources. We tried entry processor, but we want to consolidate all data from multiple named caches in the node. In a very naive form, I am thinking each named cache as a table and i am looking at ways to have a processor that will do some some processing on the related data.
I see we could use a combination of Invocable object, Invocation service and entry processors, but I am unable to implement it successfully.
Can you please point me to any reference implementation where I can do processing at the data node without transfering data back to client.
Also any reference implementation of Map reduce (at the server side) in coherence would be helpful.
Regards
Ganesan

Hi Ganesan
A common approach to perform processing in the grid is to execute background threads in response to backing map listener events. The processing is co-located with data because the listener will be called in the JVM that owns the data. The thread can then make Coherence calls to access caches just like any other Coherence client.
The Coherence Incbutor has numerous examples of this at http://coherence.oracle.com/display/INCUBATOR/Home. The Incubator Common component includes an event processing package that simplifies the handling of events. See the messaging pattern for an example: Message.java and MessageEventManager.java
I am not sure I answered your question but I hope the information helps.

Using the Execute Preloaded Option for ABAP Dataflows in SAP BODS

Hello All,
This is regarding the use of Advanced Option in SAP Application Type (ECC) Datastore settings in SAP BODS 4.2, where there are two options to select from for ABAP Execution Option property: (1)Generate and Execute and (2) Execute Preloaded. Since our ECC client is often locked by BASIS team even on DEV environment, we would like to make use of the second option 'Execute Preloaded' so that we could extract the data from ECC tables without having to ask the BASIS team to unlock the ECC client every time before extraction.
The problem is that we are getting an error upon generating and uploading the ABAP program to ECC client. I have searched the blogs and so far I have only found that there are certain ABAP programs or function modules that come with SAP BODS which need to be installed by BASIS team on ECC side to allow the ABAP dataflows to be generated and uploaded to ECC server. I would appreciate it if anyone could provide a list of which function modules BASIS needs to install on ECC or a blog that provides details around using this option.
So far, from the SAP BODS designer, we are performing below steps but getting an error upon generating and uploading the ABAP dataflow program:
1. Create a test ABAP Dataflow using SAP ECC datastore. Provide the ABAP program options.
2. Right click, select Generate ABAP Program.
3. Once the ABAP Program Generation Dialog box appears, check the box "Upload Generated Program".
4. Upon clicking OK, we are getting the following error:
The ABAP program <ZRTEST01> for ABAP data flow <RT_TEST_R3> (datastore <R3_DS>) was not uploaded: < RFC CallReceive error <Function /BODS/RFC_ABAP_INSTALL_AND_RUN: RFC_ABAP_MESSAGE- Exception condition "NOT_SUPPORTED_BY_GUI" trigger[SAP NWRFC 720][SAP Partner ### ][clientname][servername][accountname][4103]>. >.
Any help would be greatly appreciated.
Thanks,
Rizwan

All,
The BASIS team reviewed steps provided in the BODS document and attempted to install the Function Modules but now none of the BODS jobs would work. All BODS jobs are being terminted with the Syntax Error error when extracting data from ECC using ABAP dataflows:

Problem with trees(Duplication of the parent node in creation of children)

Hi guys i am experiencing a slight problem with the creation of trees.Here is a clear explanation of my program.I created a program that generates edges from a set of datapoints then use each and every edge that is generated to create multiple trees with the edge as the rootnode for each and every tree.Everything up to so far everything went well but the problem comes when i want the program to pick every single tree and traverse through the set of generated edges to create the children of a tree.What it does at the moment for each tree is returning the a duplication of the parent node as the child nodes and that is a problem.Can anyone related with this problem help.Your help will be appreciated.

Your program description makes no sense. What exactly is it supposed to do?
Your errors make no sense. What is it doing wrong?
Your program output makes no sense. Look up pre-order, in-order, and post-order notation for representing trees. Pick one of those that you think would be best. I would go with pre-order. Because what you are doing isn't understandable.
By the way, I think your concept of a tree is flawed. A node in a tree has 3 things. it has a reference to its parent, it has references to any of its children, and it has some key value that represents the node (if each node were represented by numbers, the value would be an integer or something). In the case of the root, its reference to its parent is null. I don't know what you are doing with your tree, but it is highly confusing.

How to read the details in the context node of the custom controller

Hi friends,
My requirement is i enhanced the component ICCMP_BP_DETAILS , now on EH_ONSAVE i want to read the details of the Context node in the Custom COntroller .
In custom controller from ICCMP_BP_DETAIL/CuCoBPDuplicate From this in context node CUSTOMER is there in that attributes first name last name is there i want to read those details
so can u pls provide the logic for this how can i get the values.
am very new to the BSP programming
Regards

Hi Suchitha,
when i am following the above code the lr_entity is not Bound, so can u pls suggest is there any thing is missing
i used the below mention code but lr_entity is not bound
DATA: lr_cuco type ref to CL_ICCMP_BP_CUCOBPDUPLICA_IMPL.
lr_entity type ref to cl_crm_bol_entity.
lr_cuco ?= me->get_custom_controller( 'ICCMP_BP_DETAIL/CuCoBPDuplicate') .
CHECK lr_cuco IS BOUND.
lr_entity ?= lr_cuco->typed_context->customer->collection_wrapper->get_current( ) .
CHECK lr_entity IS BOUND .
lr_entityIF_BOL_BO_PROPERTY_ACCESSGET_PROPERTY_AS_VALUE( iv_attibute = 'FIRST_NAME' ev_attribute = lv_firstname ) .
Please correct the code if any thing is missing
Regards,
Yogesh
