Multiple Node Loader
Can anyone point me in the right direction I wonder? I am
trying to have multiple RSS nodes display in the same line of a
List Component. So the title node, insert a return, and then the
Description node from each item.
OR... is there a way to insert multiple MovieClips into a
List Component?
Some of your assumptions regarding the ClassLoaders depend upon which server you're using. From experience, yes, this works quite well in WebLogic - but..
1) You have to understand that in a clustered environment, each separate node will have it's own "Cache" object in that EAR file - and that there will be no synchronization between them. Each one will be "unique."
2) If you use a Queue for your MDBs, only one Cache object will be updated - the other nodes will not receive the message (in this case, the message goes to the "first" MDB that can process it). If you want all nodes to be updated at the same time (roughly), you'll need to use a Topic.

Cluster Apex MS's across multiple nodes for load balancing?
Can Cluster Apex MS's across multiple nodes for load balancing? If Yes/No, any supportive doc's will be much appreciated.
Here is what I did ..........
I tried multiple MS's on different nodes for Apex Domain (clustered)
Deployed apex.war, i.war with targets pointing to cluster.
Apex listener techstack is shared filesystem $HOME/apex, where apex-config.xml and bdb are available
Anyone of the MS's whichever started up first is locking up bdb and 500 server shows up when internal workspace is being launched with host specific url, where as it works fine for the host which actually locked up bdb (first MS that was started)
2nd MS shows errors as below in log files ..
Caused By: com.sleepycat.je.EnvironmentLockedException: (JE 4.0.103)$HOME/apex/bdb The environment cannot be locked for single writer access. ENV_LOCKED: The je.lck file could not be locked. Environment is invalid and must be closed.
Its expected behavior until here .....
++++ I tried something to get it working ++++
Whilst both MS's are up and running, delete $HOME/apex/bdb but let apex-config,xml be as it is...now the internal workspace urls for both hosts work fine. I logged into host specific urls and navigated, created/edited users.,etc and it is all looking good but it did not create new bdb directory under $HOME/apex ...!!
Having said its working fine, the same issue repeats after the MS's bounce. So I did put a command line to delete bdb dir once the MS comes up to avoid the issue but really not sure if this is the right way at all?
Geek's ...awaiting your advice!!Hey there,
I managed to fulfill my requirement..
If its a cluster on same machine or across machines, this should work
1. Login to machine, cd $DOMAIN_HOME
2. mkdir -p Apex_lsn_config/AdminServer Apex_lsn_config/<MS1> Apex_lsn_config/<MS2> # MS1 and MS2 are the Managed Server names as appropriate
#If you are planning for cluster spawning MS's across machines, make sure you create the dir's on step 2 for each machine respectively. (in my case $DOMAIN_HOME is not shared)
3. Copy apex-config.xml from the /tmp/apex or whatever location you have it currently to Apex_lsn_config/<MS1> Apex_lsn_config/<MS2>
4. cd $DOMAIN_HOME/bin; cp -p SetDomainEnv.sh SetDomainEnv.sh.orig #Backup the file
5. Append -Djava.io.tmpdir in SetDomainEnv.sh as below for JAVA_OPTIONS # Do it on both machine if you are not sharing DOMAIN_HOME and planning cluster across machines
-Djava.io.tmpdir=$DOMAIN_HOME/APEX_CONFIG/${SERVER_NAME}
Hint: Search for "iterativeDev" and append the same line with -Djava.jo.tmpdir
6. Modify "java.io.tmpdir" from the web.xml file of apex.war as below and re-deploy the war
<context-param>
<param-name>config.dir</param-name>
<param-value>${java.io.tmpdir}</param-value>
</context-param>
7. Bounce Weblogic Admin and Manged Servers. Make sure to tail the Managed Server log to see apex-config.xml is picked from the new location.
8. Brew a Coffee for yourself :)
- You find the instructions on creating a cluster from weblogic documentation, the steps mentioned above are only to overcome the bdb locking issue whilst creating a cluster.

Deploying EJBs on multiple nodes
Hi,
Our Application works when we deploy it on a single node. But the moment we deploy
it with multiple nodes,we are getting a exception:
java.lang.NoClassDefFoundError: javax/xml/bind/UnmarshalException
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:120)
Our deployment looks correct for me.
We have specified each node in the target like:
<EJBComponent Name="ecommerce" Targets="monode3,monode2,monode1,monode4,monode5,monode6"
URI="ecommerce.jar"/>
Any clues from anyone?
Thanks,
JeevaYou didn't give the full stack trace. No thread starts executing at
Class.forName ;-)
What's happening is that you are dealing with XML, probably in your
clustered EJBs or in your HTTP session, and so it's getting replicated. The
XML pops out onto the other end of the wire, the code loaded from the system
classpath tries to deserialize it, but can't find your application classes.
That's a common problem with object transfer protocols.
Do you know where you are using javax/xml?

Using the opmn:ormi protocol with multiple nodes
Hi
If I use the opmn:ormi protocol with multiple nodes, will it load balance between the nodes or will it simply try to connect to the first node and if it can't it will connect to the second node?.
Instead of specifying multiple nodes can I set the host to point to a load balancer?
Which solution is best?repost

How to get the data from multiple nodes to one table
Hi All,
How to get the data from multiple nodes to one table.examples nodes are like A B C D E relation also maintained
Regards,
IndraHI Indra,
From Node A, get the values of the attributes as
lo_NodeA->GET_STATIC_ATTRIBUTES( IMPORTING STATIC_ATTRIBUTES = ls_attributesA ).
Similarily get all the node values from B, C, D and E.
Finally append all your ls records to the table.
Hope you are clear.

BW 3.5 works with multiple nodes for authorizations
Hi,
Does BW 3.5 allow to do authorizations on mutiple nodes? It seems that from the How to wotk with hierarchy authorizations paper, the variable can only allow filtering 1 node. for 2.0B. We have requirements to allow viweing multiple nodes in a hierarchy.
Thanks
WillHi Will,
creat a hierarchy-node variable fill by authorizations in the frontend. The type has to be multiple entries (not single value). In RSSM at the hierarchy authorization creation you have to use the F4 for selecting nodes. The F4 allows to drag more nodes into the right frame.
Cheers

How would I delete multiple nodes at a time in OSB
I want to delete multiple nodes in OSB at a time. I have a request and that needs to get rid of the Nodes instead of using multiple delete actions I want to achieve in one shot. Any suggestions
Hi,
You should be able to delete all nodes selected by an XPath expression... Have a look at this...

Hi everybody,
I'm still new in developing BizTalk app and require some help in this one problem. Appreciate your time and input to help me on this.
Basically I have an XML document as input and a flat file as output. Example for input is as per below. The "Contact" node's maxOccurs here is set to unbounded and could be multiple. (phone, fax, website, telex ...)
<root>
<CustomerName>Company A</CustomerName>
<Contact>
<Type>Phone</Type>
<Locator>03566789</Locator>
<Type>Phone</Type>
<Locator>03566790</Locator>
<Type>Fax</Type>
<Locator>03566795</Locator>
<Type>Telex</Type>
<Locator>03566798</Locator>
<Type>Website</Type>
<Locator>www.companyA.com</Locator>
</Contact>
</root>
The expected output in XML would look like below. The final outcome would be a csv file. Strictly Phone 1, phone 2, fax and telex, the rest would be ignored.
<root>
<CustomerName>Company A</CustomerName>
<Phone1>03566789</Phone1>
<Phone2>03566790</Phone2>
<Fax>03566795</Fax>
<Telex>03566798</Telex>
</root>
Example of expected output result (csv file): CompanyName;Phone1;Phone2;Fax;Telex;
In our case here: Company A;03566789;03566790;03566795;03566798;
Another example could be: Company B;036778911;;036778912;; if only 1 phone number and 1 fax number provided.
I've used Table Looping and Table Extractor and nearly got the desired result except that it is represented in multiple rows instead of one: Example:
Company A;03566789;;;
Company A;;03566790;;;
Company A;;;03566795;;
Company A;;;;03566798;
Any idea how to do the mapping? I'm kind of stuck here and it sounds like an easy problem but i could not find any example to the solution that I need here. Table looping and table extractor is ok to map from single node flat file to multiple nodes but not
the reverse like in this example.

How to create multiple nodes for a feature in PE03
Hi Specialists,
I have a requirement for australia where we need to maintain multiple nodes in a feature ( Tcode : PE03).
Action Type Action Reason
L6 00
01
L7 06
08
L2 01
Issue is : 1) How can we maintian the above values in a feature tree.
2) The SAP standard structure is using PME14 but PME14 does not contain the 2 above mentioned
fields i.e.( Action Type & Action Reason). Istead it is contained in structure PME04 .
SO how can we modify the SAP standard structure.
3) The above strucure PME14 is being read in an SAP standard report RPCPSPQ0 :
i.e Payment Summary Report tcode: PC00_M13_PSGEN . If we want to accomodate the new requirement for australia does that mean we need to modify SAP standard report / or is there a user exit/BADI available to avoid making changes to SAP standard report.
Please suggest.Can you please supply the name of the Feature you are trying to use? it will help to understand the full picture.

BizTalk mapping multiple nodes
Hello All,
Below is an example of a schema I have to work upon. There will be multiple nodes of Diviions under the root node and there will be similar number of divisions node under the mappings node. now each divisions node (under root node) will have multiple record
nodes which will each have an industry_type node. So, what I want to do is match both industry_type nodes (each under root and mappings node) and if the value is same I want to map the industry_type_value to the destination schema. So there can be n number
of industry_type nodes and I want to have equal number in the destination schema. When I am using a looping functoid along with value mapping I am getting the non matchin industry_type nodes too in the destination schema.
Please help me with the same.Hey Ashwin,

Multiple base load in same Hyperion Application
Need to have some clarity over the multiple base load in same Hyperion application. Just to give some background of the requirement our current HFM application captures the base level data in Indian GAAP reporting structure only just like any other incorporation would do in their statutory reporting format. Now we are looking at prospects and possible impact of capturing, at base level data, both as per Indian GAAP and IFRS formats- both being active but populated by different end users.
We would like to receive some valuable inputs as to how feasible it is to capture at base level, financials of different GAAP as part of same application substantiated by an example, if any. In other words what could be the possible challenges and adverse impact because of the the multiple base load. One such impact which I could foresee could be handling of business rules and validations for different base load in the same rule file.
Please provide your valuable inputs on the same.To clarify the question:
the query asks for multiple base loads - i.e Base / Lowest level data being loaded into the application (loaded thru FDM, Data Forms etc - and not Journals/Adjustments), both for Indian GAAP and IFRS, parallely
The requirement is to specifically load both Indian GAAP and IFRS as base level information - to enable both reporting journeys, in the same application.
i.e:
- 1 base load in Indian GAAP, with related IFRS adjustments to reach financials as per IFRS requirement
- 1 base load in IFRS, with related Indian GAAP adjustments to reach financials as per Indian Gaap requirements
Both hierarchies - operating within the same application - but for two different set of entity hierarchies, for two different end-user groups, with different reporting timelines.
What are your inputs, from a Best Practice approach - whether to develop such structures as part of the same application or go for separate applications - from a design, development, testing and ongoing maintenance perspective

Having multiple Node manger process in a single host machine.
I am using weblogic server(portal)10.2.
I am running the Node Manager to start the admin server.I have installed Java based Node manager in the host machine .Created a unix id ND1 and started the Node Manager utiliy with this id.
I keep on creating domain for my new applicaitons and add this ND1 in each new domain group,so that ND1 will access the new domain's admin folder.
Now when I add this ND1 in more than 16 domain groups,I got trouble in accessing the domain folder.In unix OS there is group membership limitation where a unix id cannot be in more than 16 groups.
Anyone came acroos this issue?
Possible options.
1) Can we have multiple node manager ids(ND1,ND2,ND3..etc) for a single Node manager utility in single host?
2) While starting the server,will node manager look only the nm_password.properties file in domain folder?You can boot multiple Node Managers if you change the NodeManager home. To do that, create a directory for each NodeManager and copy the startNodeManager script to it. Then edit the NODEMGR_HOME, LISTEN_ADDRESS, and LISTEN_PORT

JTree multiple nodes selection problem !
I can not make my JTree to be in multiple node selection mode.
I have custom tree model and tree node class, the tree model class
implements javax.swing.tree.TreeModel, and the tree node is an ordinary
Java object.
In this setting, my JTree is always in single selection mode.
I have tried set the selection model after the JTree has initialized, and
it didn't work.
What I missed in TreeModel implementation ? Or should my tree node class
also implements javax.swing.tree.TreeNode ?
Don't tell me just call
xxtree.getSelectionModel().setSelectionMode(javax.swing.tree.TreeSelectionModel.DISCONTIGUOUS_TREE_SELECTION);
It didn't work.Just in case anyone wants to know, I did find the magic number of files, and what the problem is. I talked with tech suppot at Adobe, and they know the problem exists, but won't fix it. I did put in a request in the "Request a Feature" form. Read on:
The magic number is 40 Canon 1Ds Mark III Raw files, and clicking on three or more keywords. The key to not having the numbers of keywords counted incorrectly in the filter pane is to click on the keywords as fast as you can before it starts to write to the metadata. If you click on each keyword one at a time, and wait about a second or more between selecting the keywords, then the counts in the filter panel for the number of keywords is not correct in relation to the number of files that you have chosen to apply keywords to. The cure for this is to click as many keywords as possible as fast as you can before the software starts incorporating the keywords into the metadata.
I would suggest to Adobe, that a nice feature would be that one could click on as many keywords as one would want, to as many files one would want, and then have a button or icon that would enable one to then apply all the keywords at once, instead of applying them as you click them as it is now. I also would love it if Adobe fixed it now instead of waiting to fix it in the version of CS5. Someone on Adobe's support line told me that Adobe would rather wait to put this into the CS5 version than fix it now. I don't think that is right, but heck, I am only one guy who depends on this software to provide images keyworded to my clients in a timely manner. I would never run my business like this Adobe. If there is a problem, and there is, please fix it now, or give me some of my money back since your product has a design flaw that is having a negative impact in my ability to to my job and run my business.
Thanks!

Drag and drop of multiple nodes between 2 trees
Hi,
I am trying to implement a drag and drop of multiple nodes between two different trees. A simple drag drop written on the lines of the demo code RSDEMO_DRAG_DROP_TREE_MULTI works perfectly fine. But my requirement is, when a child (leaf) node is dragged, if its parent is not present in the target tree, that too has to be dragged and dropped from left to right. When I try to manually add nodes to the target tree, it dumps because the node key table and drag drop object have fewer nodes than what I am trying to add. So it always dumps in the drag_drop_complete method.
I have also tried putting this code in the PBO of my screen, calling a subroutine to refresh my tree with all nodes required. But I realise that the PBO does not get called after a drag drop. Is there a way to achieve this? Any help would be greatly appreciated. Thank you.
Regards,
NithyaThere's a Multi-Select TreeView sample on the WindowsClient.com, you can download it. Then you can drag multi nodes as follows:
Code Snippet
private void Form2_Load(object sender, EventArgs e)
this.listBox1.AllowDrop = true;
this.listBox1.DragOver += new DragEventHandler(listBox1_DragOver);
this.listBox1.DragDrop += new DragEventHandler(listBox1_DragDrop);
this.multiSelectTreeView1.ItemDrag += new
ItemDragEventHandler(multiSelectTreeView1_ItemDrag);
void multiSelectTreeView1_ItemDrag(object sender, ItemDragEventArgs e)
this.multiSelectTreeView1.DoDragDrop(this.multiSelectTreeView1.SelectedNodes,
DragDropEffects.Move);
void listBox1_DragDrop(object sender, DragEventArgs e)
ArrayList selectNodes = e.Data.GetData(
e.Data.GetFormats()[0]) as ArrayList;
foreach (TreeNode node in selectNodes)
this.listBox1.Items.Add(node.Text);
void listBox1_DragOver(object sender, DragEventArgs e)
e.Effect = DragDropEffects.Move;
