Portal Network Traffic

Hi all,
I would like to know if it is possible for the SAP Portal Server to get all requested iView information from a logged on client and forward it back to the client. This way the client only talks to the SAP Portal server and the server then gathers all requested information and sends it back to the client.
Currently in my Sap Portal when a client opens a url iView or SAP Transaction iView the user browser is redirected to the source URL. I realize that this would mean a lot of extra overhead of the Portal Server, but I would like to know if its possible.
Thank you,
Troy

Questions on Federated Portal Network

Hi All,
I have a few questions on Federated Portal Network. Please if someone can provide appropriate answers
It is said that the look n feel will be same. Will the consumer have the look n feel of the producer or the producer application will have the look n feel of the consumer portal. Also, if it is required for the content of the producer portal to maintain it's own look n feel, is it possible
How to take care of the performance bottlenecks. Are there any standards available to improve the performance
Any limitation on the no of producer portals which can be configured with the consumer portal
If one portlet, has undergone some kind of change, then how is the consumer portal notified of this. Is there some kind of synchronization mechanism that takes place or this change is implicitly conveyed to the consumer portal, both in the case of Remote Delta Link or Remote Role Assignment
How does the session management work between the consumer portal and producer portal
What is meant by transitive content sharing
Regards
Nikhil

Hi Rasmus,
Is your consumer portal required High Availability? A scheduled re-bounce of the instance should help (weekly, monthly, etc.) as a preventive measure. Maybe you can observe to see how long does it take before the problem comes back (after a full cache refreshed) and then schedule your re-bounce accordingly. As much as we try to do our best, "things" happen
Or, you can adjust your cache settings (e.g. reduce the maxValidityPeriodInSecond property) to avoid the problem.

According to the following link, the cache stores only semantic objects (iViews, pages, layouts and roles); since worksets are not semantic objects, could that be why?!

I need a clarification : Can I use EJBs instead of helper classes for better performance and less network traffic?

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer

Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
2) for less network traffic
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
3) for better container resource utilization
Again, the EJB version will consume a lot more container resources.

Share network traffic between 2 parallel wireless bridges - What kit?

Dear All,
I'm a technology professional, but mainly in electronic design rather than high end networking. Hence my request for your advice.
I wish to specify some items of kit that I can ask a networking professional to fit and configure to solve my particular application.
I would like to use (and already have in place) two parallel wireless bridges between 2 buildings. One is on 2.4GHz and the other is on 5GHz. In my simple testing so far (of each link in turn), they both work brilliantly. So far, these are in place just for test purposes, but soon I will be required to make the system "live".
The reason I'm doing this is to split network traffic over both links (to possibly get enhanced bandwidth) but to mainly build in redundancy should one link fail.
What kit is required to do this (apart from the 4 access points configured as bridges)?
I imagine I may need a load balancing device(s) or possibly something more suitable for this task.
I'd like the solution to be very transparent to the rest of the system, I'd like it to "look" like it's a simple wireless bridge (but really it's a highly robust dual bridge). I hope my waffle makes sense.
Any thoughts?
Best regards,
L.O.

You can certainly copy the addresses from one machine to the other - the contact files are held in user/Library/Application Support/AddressBook. Copy all files into the same respective location on the other machine (they will overwrite any existing contacts).
If you want the address books kept in sync, take a look at SyncTogether or SeeCard Rendezvous.

Missing MSS iViews in Federated Portal Network

Hello, portal gurus, we have a FPN related issue that hope some of you can help.
We have two portal systems that we set up as a Federated Portal
Network. One producer portal, verision is 7.0, SP11, and one
consumer portal, version is 7.0 SP13. We installed the ESS and MSS business
packages in the producer portal. Those business packages came with the SAP NetWeaver
2005 installation, and they are working ok on the producer portal.
In addition, we were able to do the remote role assignment in the
consumer portal successfully. The problem is that some of the MSS
links and iViews that are shown up ok in the producer portal are missing from the consumer portal.
Have anyone experienced the same issue? Is it because the dismatch of the SP level causing the issue? Are there any fixes to this issu?
Thanks a lot for any input!
Jane

Hi Jane,
PCD content and KM content are two different things and they have different transport mechanism.
If you want to transport PCD content to another portal go to System Administration/Transport/Transport Package/Export. In PCD tree in any place create transport package and add to it objects which you need (folders, roles, worksets, iviews and so on) and save transport package file localy on your computer or server. After that go to the system where you want to locate your content. Go to System Administration/Transport/Transport Package/Import If you save tranport file localy on your computer chose client and upload tranport file.
KM transport very clear describe here How to Export KM Contents by ICE protocol using Offline Channel Beside this way you can transport KM content use program Portal Drive (very useful program especially when you need quickly transport some KM files from one portal to another).

SAP Portal Network - WebDynpro iView and SAP Application iView sharing

Hello All,
I've read about the restrictions in SAP Portal supporting the WSRP standard for application sharing. Mainly WebDynpro iViews and SAP application iViews sharing is not supported. That is in the case of a SAP Portal as producer and Non-SAPPortal as consumer.
I'm interested in a WebDynpro iViews and SAP application iViews sharing in a only-SAP Portals Network, where SAP Portals act as producer and consumer.
I've heard about the Remote Role Assignment and Remote Content Copy that are used in such case. I would like to ask if anyone knows if these can help overcome the restriction in sharing WebDynpro iViews and SAP application iViews that is present with WSRP? And if the advantage of WSPR, that is the application execution and rendering on the producer side, and as follows decreasing of bandwidth usage, is remaining in the case of the Remote Role Assignment and Remote Content Copy.
Thanks,
Mladen

Hi Manish,
for sharing content between SAP and non-SAP Portals, your case, refer to
http://help.sap.com/saphelp_nw2004s/helpdata/en/43/23fb36cad10d23e10000000a1553f7/frameset.htm
All the possibilities and restrictions of WSPR in the case of SAP EP are explaind there.
For sharing content between only SAP Portals refer to my other thread:

Hope it helps you!

Server admin not showing network traffic graph

This topic was posted a while ago with no solution, and it has been [archived|http://discussions.apple.com/thread.jspa?messageID=6953359]. I have just experienced the same problem with Leopard Server Admin (SA). It seems to be a problem on the server, not in the client admin, since it occurs both when I use SA on the server itself and a client, and deleting client prefs. has not helped. I'm presuming that there is a corrupted database or prefs. file for this graph.
All the other SA graphs show just fine. Fixing permissions has not helped, either.
Anyone have any idea where to look on the server? Thanks.
Message was edited by: Trevor Jacques

I'm pretty sure I have since I have a few Mac Mini's on the network with their home directory residing on the server and my Windows users are sharing a few daily use files on the server including a MYOB data file, also our intranet web site is hosting on the same server, not to mention I have 3 print queues there and all the outgoing mails from both of our all-in-one scan to email machines are using the same server. All of these services and users are using their computer as if nothing is wrong, so I have to assume that there is network traffic unless server admin interprets the term "network traffic" differently.

Using GRC in a Federated Portal Network

Hi All,
We are usning a Federated Portal Network and would like to do Role provisioning through GRC.I know that GRC can do role provisioning in one single portal.
I would like to find out if it can be done in a Federated Portal Environment in which I have a Consumer and Producer Portal.
In Simple Terms - I would like to Assign a role that is present in the Producer Portal through the Consumer portal (This is called as Remote Role Assignment) using GRC.
Can anyone please help me with this.
Any thoughts will be very helpful.
Best Regards,
Vivek

Hi Vivek,
I have worked with CUP and EP and it works fine. I have not used CUP with Federated Portal so I don't have idea about this. It seems it will act something like CUA for EP. Am I correct?
CUP works with CUA but for that, it has to bec configured for CUA. I don't see any separate configuration for Federate Portal. Can you open a Customer message with SAP about this?
I doubt this will work but it is worth a try. Please let me know about the outcome.

How do I time out my thread if there is no network traffic

How do I time out my thread if there is no network traffic for a given time? I have the following code listening for data:
StringBuffer requestLine = new StringBuffer();
int c;
while(true) {
    c = in.read();
    if(c == '\r' || c == '\n') {//Not sure here???
        break;
    requestLine.append((char)c);
}But how do I time this out if there has been no traffic for lets say 5 minutes?

Have you redefined 'in'?
If it's a raw socket connection, you can use the Socket.setSoTimeout method before you open the connection to specify how long it should hold it open if there is no data available.

Unknown network traffic / router traffic monitoring

So I got a new PC with windows 7 on it, and I installed this gadget that monitors network traffic, and it shows a lot of traffic that my local PC isn't showing, so I am thinking there is something running on the LAN that I can't see. I was looking to find a live, better program to monitor the actiontec router, for traffic. anyone know of anything that can maybe show me who is using all the bandwidth on my network?
i have found software for Linksys, but nothing for the Actiontec.
Thanks,
Quasimodem
Fios in Florida
Solved!
Go to Solution.

Keep in mind that when looking at Wireshark (sniffer) software there are different types of traffic:
Unicast
Broadcast
Multicast
Unicast is traffic between two devices. You will see the traffic between the PC with wireshark and another device on your local network such as a printer, another PC or the Router. You should not see traffic between another PC and the Internet for example. Using a phone as an example some calls you and the conversation is between you and the person on the other end of the phone. This is unicast traffic. Using defaults of the actiontec, IP address seen will be 192.168.1.1 for the router and 192.168.1.2-99 for devices on your network. If you have the TV service, 192.168.1.100-1xx is used for the cable boxes.
Broadcast traffic is traffic sent to all devices. Its not directed toward a particular PC but rather usually looking for information. In a sniffer trace you will see broadcast traffic. Going back to the phone example, someone makes an announcement on an overhead intercom system that is broadcast traffic. Broadcast traffic will be seen as 192.168.255.255
Multicast traffic is traffic from one device for many devices. Usually used in video feeds. Using the phone system as an example someone wishes to tell a group of people something so instead of calling each person up and telling them each person who wants the information joins a conference bridge. Anyone is allowed to listen but only those that wish to get the information receive it. Generally how multicast works. Multicast traffic will be seen as IP address 224.x.x.x or something of the sorts where the address will be 2xx.x.x.x.
I hope this makes sense. Probably more information than you needed but at least it will help you understand what wireshark is telling you.

How to integrate PPM 5 with Federated Portal Network

Hi experts,
If we are using PPM 5 standalone (without portal) and we want to include it into Federated Portal Network, which steps we have to follow to configurate PPM in the Federated Portal. Do we have to install stack java for PPM 5 at portal level or can we have PPM as producer without stack java in the consumer (federated portal).
Thanks a lot,
CAMILO URIBE

Hi Camelo,
For PPM 5.0, you need only abap stack only. For the portal you will need java stack also.
Business packege need to be applied for PPM 5.0 and the necesarry settings need to be done in portal to access PPM through portal.
The federaed or non-fedarated option is for portal only and it will not impact the decison of accessing PPM through portal.

Amit

CRM factsheet and BI 7.0 Web-Templates in Federated Portal Network Scenario

Hi All,
i have some essential questions regarding a Federated Portal Network Scenario.
Our costumer works with 1 CRM-Portal (CRM 5.0, EP 7.0) and 1 BI-Portal (BI/EP 7.0).
He decided to implement a Federated Portal Network, using the CRM-Portal as the Consumer-Portal.
In the CRM-Portal we are working with the Business Package for SAP_CRM which also comprises Reports that are called from the BI.
The BI-Reports (BI 7.0 Web Templates) are now stored in the BI-Portal
How i can assign these BI-Reports (producer) into the factsheet of the CRM-Portal (consumer)?
Is that generally possible that the facsheet of the Consumer Portal (CRM) works togehther with BI 7.0 Web Templates from the Producer-Portal (BI)?
Best regards
Mustafa Darwish

It's been solved.
See note: 1058268 - BI 7.0 WebTemplates do not run in CRM 5.0 specific iViews

SAP DMS - SAP ECC network traffic

Hi all,
I have the following situation:
The SAP ECC servers are hosted outside my company and we are planning to install a SAP DMS server.
We have 2 options: host the SAP DMS outside or install SAP DMS in our datacenter.
When the SAP user attaches or reads a file to/from SAP DMS, how is the network traffic ?
Is there any traffic fom SAP ECC to SAP DMS or the file goes to/from DMS from/to end-user ?
How SAP DMS impacts my WAN ?
Best Regards,
Leonardo.

Leonardo, I have done some research / trouble shooting and architectural changes to raise the upload / download speeds, there are several dependencies like Network, Application, hardware etc but to your question:
First of all, DMS is a core functionality of ECC and utilizes both ECC for execution and Content Servers (recommended for Obvious performance reasons) for Data Storage. For your case I recommend that you host Content Server at the Data Center (assuming you have no other option) and have a Cache Server installed Onsite. (This requires minimal maintenance). When the user uploads a file the traffic is high as the entire File needs to be transferred to the data center, on the other hand Cache server (if installed onsite) considerably reduces the retrieval time.
Again having said above there are several other parameters that could affect your upload / download speeds.
Hope you'll find this useful, let me know if you have further questions.
regards

MDNSResponder problem / network traffic reduction measures in effect

[Part I in a series of "Why Does My Machine Randomly Shut Down And Related Oddities" :-D ]
Below you can see a bunch of log output which seems to show a network problem. My connection is not too fast, which I've blamed on my low tier of U-Verse, but this makes me wonder. And it seems to occur each wakeup.
"network traffic reduction measures in effect" I've found mentioned as an AirPort problem.
BUT, my AirPort is OFF.
(Plus, why is it changing the host name and then back again?)

Is that an actual dump from your logs? If so, I find it strange - not least because the timestamps are not consecutive. That certainly makes it harder to trace what's going on.
Deciphering it as best I can, I'd say you have a flaky network. This could be due to cabling or some process on the machine that's interrupting sleep - I find it strange that many of the mDNSResponder messages are timestamped while the machine is asleep. That could be related to the various wake-on-LAN options - are they enabled in System Preferences -> Energy Saver?

UWL in Federated Portal Network

Hi All,
Can anyone please suggest how UWL works in case of Federated Portal Network? I have a requirement to show the tasks, alerts, notifications from more then one Producer in the same UWL iview on Consumer.
I followed the steps as mentioned in the SAP help document Running the UWL in the Consumer Portal http://help.sap.com/saphelp_nw70/helpdata/en/45/8084e2e8c9487fe10000000a114a6b/frameset.htm but no luck.
I would appreciate if anyone can let me know the proper process for doing this or could provide any document for it.
Thank you in advance.
Regards
Seema Rane.

Hi Seema,
There are two ways to configure UWL on the federated portal:
1. Run UWL on the Consumer Portal:
a. Everything must be copied over, including xml files. Retrieve information directly from the backend. Use the IviewLauncher Handler. This uses the remote delta link from the producer.
Have a look here at the help documentation:
http://help.sap.com/saphelp_nw70/helpdata/en/45/8084e2e8c9487fe10000000a114a6b/content.htm
2. Run UWL in Producer Portal:
a. Here the configuration is predefined.
b. Use remote role assignment or remote delta links
producer remote delta links should be available as remote delta links on the consumer.
copy as remote delta links; config is done on the producer
Have a look here at the help documentation:
EP7
http://help.sap.com/saphelp_nw70/helpdata/en/45/81ab2f3bab6975e10000000a114a6b/content.htm
(for nw701, 702, 720 search the help documentation accordingly)
I hope that this information is helpful to you.
