Restiction on maximum no of portlets in one portal

Hi,
Is there any restriction on the maximum no of portlets which can be there as 'available'
in one portal(Page)?
We have around 127 portlets available in one portal and when we try to make more
portlets available from Weblogic Admin tool then it doesn't work.It makes existing
channels unavailable.
Please send some info if you are having on this.Its very very urgent.
Thanks,
Bharat

Hi Ashish,
I think there is no limitation to this.

How do I add multiple portlets to one provider?

Hello,
I'm using JDeveloper 10g. Created an Application Workspace which holds several projects (java/jsp porlets). I would like all of these portlets to be under one provider rather than registering a provider for each project. Do I choose one project and add information to the provider.xml file for my other portlets? If anyone could help, it would be appreciated...
TIA

[Matthew: think I understand. Is it safe to use a provider for each portlet? If I had a hundred portlets would it effect system hardware requirements with multitude of providers running? Now I'm trying to determine if I should combine each project or if I should leave them seperate. Thanks again...]
Matthew - Would be good if you could hit "reply" to the last concerned post. I had some trouble trying to find whether you had posted any more questions ;-)
here's my response to your last post:
There is definitely a performance hit when you have just one portlet under one provider. First - You will have to undergo 100 provider registrations and I'm sure that can drive anybody crazy ;-)
Secondly, for each provider, there is a ProviderDefinition object created in memory. In your case, there would be 100 such objects created at any point in time (assuming 100 are in use). had you classified portlets under say 10 such providers, you will definitely save memory. For each instance of the provider registration, you have one ProviderInstance object created. So even if all these 100 providers are registered once on Portal A, you will have 100 instances of this object. When registered on portal B, 100 more will be created. This will be sufficiently less if you had just 10 top level providers.
As a best practice, you might want to group related portlets under one provider e.g. If you are having a bunch of SAP, Oracle, PeopleSoft portlets, you could create three top level providers and just add those portlets accordingly. Just an example though. the classification is totaly based on what binds two portlets together and is something that will have to be decided by you.

Error in RFC Adapter PI 7.10 maximum size of requests for one LUW

Hello all,
I have a big issue on our Development - SAP PI 7.10 System. If I try to push a RFC from a Client System
I get follow error messagei in the Runtime Workbench (RWB) back:
processing error to be caused by: com.sap.aii.adapter.rfc.core.server.RfcServerException: maximum size of requests for one LUW has been reached (1). handling of request for tRFC (TID: 0AA001B8712C49D35D4D06C2) not possible (server: RfcServer[PKG_R3_D07_600_RFC_SND]1)
But I don't know why. I checked follow OSS Notes:
730870 and 774705 w/o success. It will be nice somebody can help me.
Thanks
S. Kohler
P.S. We have the same scenario in our Quality SAP XI System and there works. I couldn't find any
differences between the Adapters. Is there a problem with the parameters ????

Hello Tarang Shah,
okay. Here again ( I thought I mentioned above):
in Q50 (SAP PI 7.10 System) we create a RFC Server with the program ID RFC_Q50.
in D64 (SAP PI 7.10 System) we vreate a RFC Server with the program ID RFC_D64
in D07 (SAP R/3 4.7 x110) we create a RFC Connection to D64 with the program ID RFC_D64.
The testconnection works well. I see in our Dev. SAP PI System (D64) that the connection works.
The problem is here, if you start in the application (System D07) the push, you get the error :
maximum size of requests for one LUW has been reac hed (1). handling of re
in Q50 (SAP R/3 4.7 x110) we create a RFC Connection to Q50 with the program ID RFC_Q50.
The testconnection in Q17 works well. Also the push from the application (System Q17.)
This means, the functionallity is okay on both sides (Q17 and D07) only the application sending
process from D07 makes trouble ( you see in Transaction SM 58 on Client Site, the error as I mentiond above and in SAP PI side.) It seems that SAP PI could't accept more as one LUWs
in the same time. Q50 (Q- System) accepted.
So, this is the reason in my point of view, that the problem isn't the connection, seems more
an paramter problem in D64 side. But I don't know which parameters. I checked the OSS Note 730870 and 774705 w/o success.
Thanks

Maximum no'of Objects for one class

Hello friends
Please, tell me....Maximum no'of Obects for One Java class.
Thanks & Regards
S.Rajakrishna

Is there any limit of creating the objects for One class?Instantiated objects go into the heap. There is only one heap for the whole JVM. There is no correlation between objects in the heap and the individual class files.
100,000 objects may or may not fit into the heap. In general they probably will. If you don't, then yes, you'll get an Out Of Memory exception.
Regardless there is no excuse for loading 100,000 objects just to render a JSP! You don't imagine your user is going read all of them do you? Restrict them to the number of objects that the user is actually going to be able to handle at any given time.
You can do this by putting WHERE clauses on the hibernate query, and/or by setting limits (setFirstResult and setMaxResult) on the Query object before listing it.

Migrate page w/ Disco portlets from one 9iAS portal instance to another?

Hi.
Has anyone migrated pages with Discoverer portlets from one instance of 9iAS portal to another?
We want to maintain development and production 9iAS setups, and need some mechanism to move pages wholesale from one app server to the other.

Hi Sumit,
Thank you very much for the early response.
The personalization has been done at the Site level.
After migrating the code the server was bounced.
On the executing the script given by you i.e jdr_utils.printdocument('/oracle/apps/pon/negotiation/creation/webui/customization/site/0/ponDefineHdrPG');
Its giving "Error: Could not find document /oracle/apps/pon/negotiation/creation/webui/customization/site/0/ponDefineHdrPG".
Can you please guide me what i am missing.
Waiting for your reply at the earliest.
Thanks and Regards

Hello,
RFC destination progid created in R/3 should be same in XI system either D or Q system
In your case check the RFC destination used and progid associated in that and make sure that the same progId exists in the system you want to receive data
Note : progID is key for receiving data so make sure only one is active at a time.(in your case required D or Q s id in other system change the progid)

Deploying ADF/JDeveloper portlets in WebSphere Portal

I'd like to use ADF/JDeveloper to build my application, but my customer is already heavily invested on a WebSphere Portal deployment platform. The JDeveloper/ADF documentation has extensive information on creating portlets in various ways, but they all seem focused exclusively on deploying in an Oracle platform. I have tried both the "Standards-Based" as well as the "JSF Portlet Bridge". I have tried to deploy the portlets in WebSphere Portal using both the generated WAR file, as well as by registering the WSRP producer. None work.
With the WAR file, WebSphere Portal seems to import the WAR file just fine, and I can add a portlet to a page, but the portlet always shows as "unavaiable"
With the WSRP producer, I can get something to show in the page, but the functionality within the portlet doesn't seem to work.
I've searched extensively, but cannot locate any documentation or use cases for deploying portlets from JDeveloper into WebSphere Portal. Does anyone have any thoughts?

Dvohra21, again, I apreciate the effort, but I think you're missing the fundamental question.
You've given me two types of articles/links. Some are generic WebSphere Portal documentation about deploying a portlet from a WAR file. Others are Oracle articles about who to generate portlets in JDeveloper, with examples deploying in Oracle/WebLogic servers. Unfortunately I don't have a problem with either of those.
I CAN deploy a portlet WAR file in WebSphere Portal, and sucessfully add it to a Portal page. I have done that with multiple WAR files generated from Rational Application Developer.
I CAN produce a WAR file from JDeveloper, following the instructions in the same resources you included, plus a few others.
The problem is, the WAR file from JDeveloper, does not successfully run on WebSphere Portal. I create a simple Hello World portlet in JDeveloper, and I can generate a WAR file from it, and seemingly deploy to WebSphere Portal. However when I add it to a Portal page, it always displays only a blank box with the text "This portlet is unavailable". This is in the same exact portal page, where the portlet created with Rational Application Developer shows up just fine right along side it.
Bottomline is, although there is a great deal of information an demos about generating portlets from JDeveloper within an Oracle environment, I could not find a SINGLE ONE, that goes through an end to end scenario where it is deployed in WebSphere Portal. Nothing in this forum, nothing in Oracle docs, and nothing I can find on a Google search.

NPE while registering Remote Portlet in Weblogic Portal 10.3

I am on Weblogic Portal 10.3 and am trying to create a remote portlet in my portal application. The remote Portlet is hosted on OC4J 10.3.1.1.1 and is consumed properly on Oracle Portal without any errors, however, when I try to access the portlet's wsdl via the Remote Portlet Wizard, I get the following exception while registering.

Query- IPC using JSF Portlets in WebLogic Portal

The question is how to pass data when doing InterPortlet Communication using Local JSF portlets in Weblogic Portal.
I will eloborate on the particular scenario we have below.
Two JSF portlets are build (both are not using Java Page Flows). The first porltet has a table of data. When the user clicks on one of the items in the table (which is coded using <h:commandLink/> option), the second portlet should show some details on the item clicked.
For example:
If there is a list of books in first portlet, when clicking on one of the book name, the details of book should come up in the second portlet.
To achieve this, faces event was enabled in first portlet with requestAttrPersistence option set to session.
For example :
<netuix:content>
<netuix:facesContent contentUri="/bookList.faces" requestAttrPersistence="session">
<netuix:facesEvents>
<netuix:facesEvent action="/bookDetails.faces" eventName="bookDetailEvent"/>
</netuix:facesEvents>
</netuix:facesContent>
</netuix:content>
The second portlet was configured to handle faces events, particularly the bookDetailEvent.
Example:
<netuix:handleFacesEvent eventLabel="handleFacesEvent1" eventName="bookDetailEvent" fromSelfInstanceOnly="false" onlyIfDisplayed="true" sourceDefinitionLabels="JSFPortlet_1" sourceDefinitionWildcard="this">
<netuix:invokeFacesAction action="/bookDetails.faces"/>
</netuix:handleFacesEvent>
Going by this method, how can we find the particular book whose detail has to be shown? As in JSF, we dont directly access the request attributes, what is the ideal way to pass data from one page to other?
Please help on this.

i am also having the same problem.I tried by passing _nfls=false but it didn't work.Can you suuggest where do i need to set this or any other parametrs such as this programmatically?

How to register Business Object Portlet in Oacle Portal

Hi Gurus,
Could anybody give me an idea How to register Business Object Portlet in Oacle Portal.
Thanks & Regards
Vikram

Hi
I am also looking into BO portlets but maybe I am one step behind you as I am still trying to find where to download the provider from.
Could you tell me where to got the portlet from.
I recently went to the Business objects web site and could only find a java portal integration kit for JSR 168 platforms (10g included in the list)
at http://www.businessobjects.com/products/downloadcenter/boepik.asp

Sun ONE Portal Server on Windows

I've heard that the initial release for Sun One Portal Server will be available only in Solaris, but the Windows and Linux version are in the works and scheduled to be released during the first half of 2003.
Anybody can confirm this issue?
When will a Windows version be available for download?. Is there a beta version yet?
Regards,
Guillermo.

portal application means
1- portlets (portlet logic + portlet view)
or
2- channel + provider (original Sun portal components)
have a look at
http://docs.sun.com/app/docs/doc/819-1370
additionally you can develop JSR168 portlets in combination with JSF straight with Sun Creater 2
which is currently available as a free beta version

Using common httpsession in Remote Portlets of Weblogic Portal

I am using Oracle's Weblogic Portal and I am using multiple remote Producers in Portal application, I want too know if I can use common Http Session among multiple Producer Portlets?
I am consuming Portlets from Producers in one portal and I have one common Login for Portal.

There is a much easier pattern for this, but it may or may not serve your needs. You can use Community Preferences. You can set/get them from portlets, control who sets it using portlet security, etc. The one difference is that you won't see it enumerated with the other community properties when you edit a community in the admin view.
Another option is to do as you planned; you would need to use the plumtree server API to update the data, but you should be able to fetch it using the remote search API. might want to post questions on the respective discussions (native API and prc) for those questions...
