Using Basic or Multi-tier configuration for WLS Clusters...

Ok,
          The scenario is: I'm using WLS6.1 (hopefully, version doesn't matter here)
          with three instances clustered. Each instance provides all Services:
          Servlets / JSPs/ EJBs / Database communication... I'm using the Basic
          configuration described on the BEA documentation....
          Now, I want to move forward to a Multi-tier configuration, where the first
          layer will serve Servlets and JSPs and the second layer will serve EJBs.
          The problem: On the first scenario, I was looking EJBs with the Default
          InitialContext() constructor without the environment, since everybody was on
          the same JVM...
          What do I have to do, so my Servlets start looking for EJBs on the second
          cluster now? Do I have to re-write every single lookup? Can I use a
          jndi.properties file on the first layer - on the presentation tier?
          Thanks in Advance,
          Marcelo.

          Thanks Patrick!
          But my actual problem starts here. The Servlets aren't mine. We have to support
          applications which run atop our product(which is a bunch of beans+RMI Objects
          running on the top of WLS) in a backward compatible way with a standalone.
          Will try and make a post if I can find a 'configurable' way out.

Timout configuration for WLS 5.1

Hi all,
We're running Tomcat against WLS 5.1sp10.
We're trying to find out how to tune the timeout properties for the
different connections.
If we have a connection to our Oracle database, it will timeout and fail
after 300 seconds (5 minutes). However, when Tomcat connects to WLS, it has
a timeout of only 4 minutes.
We've discovered that if the connection gets dropped to WLS while it's
blocked talking to Oracle, then this "consumes" a connection to WLS, and if
it happens enough, WLS will get its Listener hammered and stop accepting any
kind of connection.
What we're hoping to do is prevent this by having Tomcat time out "later"
than Oracle, this would allow Oracle and WLS to fail "cleaner" than if
Tomcat fails first.
However, we can not find any place to adjust either the 4 minute timeout on
the client side or the 5 minute timeout on the server side.
We know that we can somewhat circumvent this by expanding the number of
Execute Threads, but I'm thinking that the timeout adjustment (as well as
ensuring that really stupid SQL doesn't happen in the first place, but
that's a different issue) is "better" than tweaking the Execute Threads
count.
Any help appreciated.
Thanx!

Hi.
trial license keys come with the server when you download it. It should
be good for 30 days. Try downloading the server again if your license
has expired, or contact sales for a license extension.

Same Certificate for WLS Clustering?

Hi all.
First of all, is it worth to have 2 way authentication SSL connections among
the weblogic servers under the same weblogic clustering?
I'm wondering if I can set up same certificate/private key pair into all
weblogics running on the same machine under
weblogic clustering? or do they require to have unique key pairs?
To make 2 way authentication SSL between IIS and weblogic server, does IIS
have to obtain certificate from
trusted CA such as Verisign? Can IIS and weblogic server running at the
same machine share same certificate and
private key?
Thanks in advance.

certificate is associated with a unique private key. So, unless all the
machines have the same machine name, (ala machine.com), you'll need a
different visual certificate.

mechanism for storage of the private key.

Want to use an iPod photo configurated for Mac on a PC

I want to use my old iPod photo (configurated for Mac) on a PC (but do not need to keep my songs and photos). Is this possible? If so, what do I do?
iMac G5 Mac OS X (10.4.8) iPod 5th generation 60 GB

If your iPod is formatted for Mac it won't run natively on a PC because the Windows OS does not support the HFS Plus file system and therefore will not see the drive. Macs can read Windows drives so you could restore and format the iPod on a PC, this would also mean any future software updates would have to be done on Windows. This will erase your drive so you need to have your songs and photos backed up. Alternatively there are third party programs that will allow you to use a Mac formatted iPod on Windows, this is one for instance gets good reviews and has the functionality to let you copy content from the iPod to the PC. Not sure if it does photos but have a look: XPlay 2
You can read another user's experience of using XPlay at this link: iPod on Mac and Windows

Access Point configuration for flat network

We have recently aquired a remote location which has a pre-existing flat network (172.16.X.X/16). Before we are able to convert them over to our new IP scheme, they have a need to have wireless connectivity on site. We have 4 1142's which I need to configure for them. I have experience configuring WLC's and autonomous AP's for networks with multiple vlans but have never configured AP's for a flat, single subnet network. I need to configure them for either guest access (internet only) or corporate access to network resources with radius authentication. Do I configure a native vlan as I would for a typical multi vlan network? Do I configure the switch port as an access port as opposed to a trunk beacause of the lack of layer 3? I basically need a sample configuration for this situation.

since you are on flat network, you just need to configure the SSID, no need for subinterfaces. With the AP only servicing the one VLAN you can leave the port as an access port as well.
as they are on the only subnet, I wouldn't do a 'guest' SSID. I would go with just the corporate SSID with WPA2/AES/802.1x. So the config is exactly the same for the RADIUS server and the SSID, but greatly simplified since you don't have to sub-interface anything.

Documentum Kpro configuration for SAP DMS

Hi Experts ,
We are planning to use Documentum Content server as the content store for SAP DMS . We want to configure the KPro configuration for this. Can somebody help with the details. We are currently using Documentum SAP archivelink (RFC ) . I know we can also use Documentum SAP archivelink (HTTP ) . What is the difference between using Documentum SAP archivelink (HTTP) over Kpro configuration.
Please guide me
Thanks
Regi

Thank You Seema and Nitin for your answer.
As I mentioned earlier I am aware of the configuration of the Content Store and othet Data Carrier .
I am also familiar with the regular Documentum SAP archive link (RFC/HTTP).
The new dimension we are bringing to our architecture is adding SAP DMS for SAP PLM and using Documentum as the content store.
We want to use KPRO as the integration configuration for the specific reason of more than 2 originals.
My question to all the gurus out there is did any one use Documentum KPRO configuration with SAP DMS and if so how does that work with ECL viewer .If you are using Archivelink , you need to use Documemntum Viewer to see documents from SAP.
Also any difference in viewing document from a Portal interface
Thanks
Regi

Using Basic or NTLM for PSC to PO communication

Basic authentication is the easiest to get working, so we generally recommend that users start there, especially when setting up your first IAC environment. Consider NTLM as a more secure advanced option.
It can be diffcult to troubleshoot the NTLM issues described below, which is why we recommend basic for beginning users.
Now the NTLM option is more secure than basic authentication, which sends the password in clear text over the wire. This may not be as much of an issue if you use SSL, but it is certainly best practice to use both NTLM and SSL. So in a customer environment, it is best to work through these concerns to estanblish security. We are seeing more and more customers doing security audits, so we will want to make customer environments use NTLM.
A challenge with NTLM authentication is that the list of supported authentication schemes in the 2 products do not match.
PO uses whatever version of NTLM the domain is using. You can’t actually select v1 or v2. In the future we will make a UI change to indicate that this is vvulnerable to the domain of the account you specify and what version of NTLM it is configured for, but for now you need to undersdtand that. At the end of the day, it’s in PSC where you specify the account which will determine which doimain is used. If you’re using anything newer than W2K8R2, you’re probably running v2, unless you’ve manually set the domain to downlevel (e.g. for legacy application compatibility). PO is at the whim of your authenticating domain as to which version of NTLM will be required.
In PSC, one specifies exactly which NTLM version is to be used in the authentication.
Also, when specifying the connection in IAC of PSC, NTLM is actually NTLM v1, while NTLM is v2.
So in the IAC configuration wizard, if you are going to use NTLM, you need to specify the NTLM version to match the domain of the user credential you use to connect to PO, specifying NTLM if it is v1 and NTLMv2 if it is v2.

When I add a while loop to the vi "niScope EX Multi-Device Configured Acquisition (TClk)" to acquire data for multiple times, it works but it runs very slowly.

Because I want to acquire the similar data for multiple times and then take an average to increase SNR, I add a while loop to the vi "niScope EX Multi-Device Configured Acquisition (TClk)". It works but it runs very slowly (about 1 sec for each iteration). I think I had put the while loop at a wrong position, which makes the vi run from the very beginning in each iteration. So I really want to know where should I put the while loop to improve the speed? I have attached all the vi and subvi.
Thanks very much.

Dear Zainykhas,
Thank you for posting this to the discussion forums and for uploading some sample code. I took a lok at the issue you have been having, and it is unclear to me as to why you have placed two for loops around the original while loop. My understanding is that you want to use the original Sample.vi and want to execute this N times where N is the Max Freq divided by Interval so that you can scan for a range of frequencies.
Why not just put Sample.vi around one for loop and use the increment counter scaled by the interval to count up towards Max Freq and insert the desired Frequency into the cluster using Bundle By Name?
Kind Regards,

Basic 877 configuration for a beginner

Hi
I am a beginner in the field of Cisco, having decided I am tired of consumer products that regularly crash. So I bought a Cisco 877 router to connct to my broadband ADSL here in the UK.
I was led to believe the SDM would allow me to set up the firewall/router easily, but it's much more complex than the consumer devices!
So I have a number of basic beginners questions. Here's what I want to achieve, and if I can do it via SDM that would be great. If not, I'd need help to do it from scratch at the command line (a place I don't really want to go!).
1. Connect to my PPoA provider (who I believe uses MUX rather than SNAP).
2. Run a web server, Exchange server and FTP from inside my LAN
3. Collect POP3 mail from external email accounts into Exchange (with a POP3 connector)
4. Use Remote Desktop to get into my server from out of office
5. Access the LAN using a simple Microsoft VPN
6. Allow one of my LAN workstations to access streaming radio (I know the ports and protocols it uses)
All this is simple in, for example, a Netgear consumer box. Port forwarding and port range forwarding are easy and there's no trouble with NAT - it just works. But making any of this work with the Cisco 877 has been impossible for me.
HELP!!!
Please bear in mind that I don't understand all the terminology (thoughh I do understand basic networks, IP addressing etc). The number of interfaces on the Cisco are a bit confusing, whether the switch ports need me to assign them IP adresses etc, ACLs and inspection rules etc are a bit of a dark area!
Can anyone help?
Nick

hi
let me put some guidlines for you here
1. Connect to my PPoA provider (who I believe uses MUX rather than SNAP).
included device manager through the web interface is perfect for this. just click on the appropriate options and your connection will be established. of course you'll need some basic information regarding to the ip addressing and authentication from your provider
2. Run a web server, Exchange server and FTP from inside my LAN
first of all you need a permanent IP address on the wan side for this. also you can try to use some kind of dynamic dns service for this (dyndns)
also you'll need to set-up nat translation for this, so the packets destined to your external address will reach the server within your internal or dmz zone
3. Collect POP3 mail from external email accounts into Exchange (with a POP3 connector)
it is simple. established connections should be leave your internal zone w/o any problem
4. Use Remote Desktop to get into my server from out of office
another nat rule should play here
5. Access the LAN using a simple Microsoft VPN
this router has some internal vpn functionality both for client vpn and ssl vpn, but I never tried this
6. Allow one of my LAN workstations to access streaming radio (I know the ports and protocols it uses)
it is also established connection, so shouldn't be any problem
Another issue with this stuff. When I tried to use the modern stateful version of the FW included in this software it never worked, so I had to revert to the old fashioned nat/access-list based FW config. Maybe you'll have more luck with this, so just click next next finish :)
altought, Cisco FW is not a beginner level stuff, so if you need advanced config (even if you need server in a dmz), you should hire someone to configure it for your needs

Laszlo

Multi-language support for user-specified text strings used in the forms

multi-language support for user-specified text strings used in the forms
Instead of creating multiple forms, 1 in each different language, for the same service, is there any workaround?

Hoan - is your question what are the considerations when creating multiligual catalogs? If so, I can tell you that at other clients I have seen them use a single catalog for one or two languages. For the two langugages, such as Spanish/English, you can create a single catalog with both of them. Once you get to more than two languages, the catalog would get unweildy and is therefore not suggested.

Doesn't play songs, "itunes is not configured for use with mac-formatted"??

Hi, new ipod shuffle. Seems to charge fine, all indicator lights function as expected. Everything looks fine in itunes. But it doesn't play songs. I have the most recent versions of itunes and the ipod software. Re-set, updated, and restored, nothing works. Even restored using the restore utility. Re-started computer. Checked for volume control. Won't play songs. Tried different file types. Songs play fine from itunes library and from the device's library within itunes. Tried different headphones. Hooked it up to computer speakers. Turning volume all the way up on device and speakers, heard some very faint rhythmic static, so my guess is the jack socket (or whatever you call it) is just messed up, but it seems weird that it can transfer power and data to the device but doesn't work for sound...
The only other issues that have come up is that the drive disappears in explorer once it syncs with itunes. Other people who've noticed this seem to have completely different problems so I don't think it's related.
Also, I have MacDrive on my computer. And when it starts up with the ipod plugged in, MacDrive offers the message "Itunes is not configured for use with Mac-formatted ipods." It offers to automatically reconfigure itunes so it can read mac-formatted ipods. Since I've restored the device, I don't see why formatting should be an issue so I say "no."
Should I try letting macdrive do its format thing? Should I try formatting the ipod disk on the My Computer menu? Or should I just email apple and tell them the jack's busted?
Thanks for any thoughts!

Well, I have had my iPod for about 3 years, it is a 4th generation non-video 40 GB. One day it just stopped working, and now it does not play any songs. when I turn it on it makes this odd whirring sounds that computers make when they try really hard to do something. I cannot charge it, and it is not recognized by iTunes. Also when I turn it on, I get the apple.com/ipod/support (or whatever it is) screen. Needless to say, my warranty is expired, and so I cannot do anything for it except get a new battery, or buy a new one. Is there any way to fix this problem, or anyone out there who is experiencing the same thing?
I'm having the exact same problem with my wife's iPod. However it will play about 3 seconds of a song and go onto the next song.
If there is anyone out there that can help please do!

Yes, it will do a full backup.
and if so, do I really need all the old backups on my smaller external drive?
Only if you want to be able to go back in time to those previous Time Machine backups. When you plug in the new larger external drive, you will only be able to go back as far as the first day you plugged it in and ran the first Time Machine backup on it.

How to use different configurations for KDE Plasma?

I typically use my laptop in two ways: single monitor and dual monitor. I like to have in the two cases two different sets of widgets and plasmoids, so I wonder if it's possible to have multiple configurations for Plasma and load the desired one when needed. I searched around for a solutio but didn't find anything.
Right now, I'm using a rather awkward method: I have two sets of Plasma configuration files for single and dual monitor setup (ie., plasma-desktop-appletsrc-single and plasma-desktop-appletsrc-dual) and two startx scripts which, before starting KDE, copy the single or dual monitor configuration on the standard Plasma config file (cp $HOME/.kde4/share/config/plasma-desktop-appletsrc-dual $HOME/.kde4/share/config/plasma-desktop-appletsrc). I'm sure there are better ways to have a dynamical Plasma configuration, since my zero-order solution has many drawbacks, for example I loose the modifications I make on my desktop (since Plasma saves them on plasma-desktop-appletsrc which is overwritten at next startup).
Can anyone please help me? Thanks.

For such a purpose KDE Plasma provides Activities. Here you can find more about that:
http://userbase.kde.org/Plasma#Activities
There is also a nice plasmoid for easy Activity managing:

CTS+ Configuration for Transporting non-ABAP objects in Portal Landscape using solution manage 7.1 sp8

Hi,
Currently we have cts+ already configured for our portal systems in our landscape through solution manager 7.0.
Recently we had setup a new solution manager 7.1 and need to perform cts+ configuration using this new solution manager 7.1 as we are planning to remove our old solution manager 7.0 very soon.
We are using NWDI system for transporting our portal transports.
Please help me with steps on how to configure cts+ using solution manager 7.1 using NWDI.
