How to handle changing IPv6 network configurations

Hi,
I run a Mac Mini as a server with OS X Server 10.8.5/2.2 on it using an internet connection with DS-lite. The server runs fine on a private IPv4 and a public IPv6 assigned by the ISP thrugh my router. Now from time to time (on some really odd days 5 times a day) my ISP decides to change my IPv6 prefix and as a consequence the IPv6 of my server. This results in a warning and some services seem to work not always properly. When I handle the warning and update the network configuration (although all relevant pieces of configuration that are shown along this proces remain unchanged), everything is back to normal.
Now I wonder whether there is better way to handle changing IPv6 prefixes while everything else is unchanged? Any thougths? Thanks. Steffen

I'll add my 2 cents too Sudheer...
I suppose your versioning strategy should take into account your particular circumstances, impact analysis, ESB architecture etc...
In our case it makes sense to version the service operations because we have some consumers that want to stay on the older version & other that want to move with the changing versions...
We've noticed that SAP, with the standard delivered enterprise services also version step the service operations so you esentially have 2 service contracts but one that caters for additional fields/functionality. The consumer uses the service operation that they prefer.
The other possibility, if you are in a position to make the new fields 'optional' then you could do that without impacting all the consumers, the consumers that have the additional info to pass in the request can do so & the other consumers can carry on business as usual.
Then you could also version step the entire service, that would entail making use of a new software component version but this would entail new endpoints & depending on your architecture it could impact all your consumers. If you're using an integrated ESB architecture, your consumers would have one endpoint & the ESB would route the request to the relevant service version.
So you could minise impact on the consumers & develop a good versioning strategy depending on what your current situation is.

Hi,
What is the exact printer model?
If it is the HP Deskjet 1510, this is a USB printer and it does not offer any network capabilities.

How do you abort automatic network configuration setup to start fresh?

Hello all -
I am the sole user of the sole Sun workstation where I work. We recently switched from a DHCP network to one which requires static IP addresses on our machines. I did a sys-unconfig to set the network to a "blank" state and rebooted the machine. I was told to randomly select an IP address of the form 192.168.2.XX. Having done so, I managed to choose an address that was being used by another machine. So here is where the problem begins.
Now when I reboot the machine, the machine complains 3 times as follows:
"WARNING eri0 has duplicate address 192.168.2.XX (in use by 00:1d:09:76:25:da); disabled"
and then begins again to try and configure the network (asks if I have a subnet, if I want to use IPv6, etc). However, the configuration process does not start from the beginning (i.e. does not ask for a host name or static IP address, it just skips to the subnet question). As I go through this process, the system eventually says:
"The IP address previously set on the network interface is no longer available. The system state is corrupted. System identification can no longer continue. Press Return to continue".
Pressing Return simply repeats the above message and I appear to be stuck.
How can I abort the network reconfiguration process? I'd like to do a sys-unconfig once again and try a different IP address.
I'm using a SunBlade 2000 with a Sun keyboard and a Sun monitor running Solaris 10.
Thanks very much, Lynne

Boot into single user mode: "boot -sw"
If you entered everything correctly but the IP address, you can just change the IP address by editing /etc/inet/hosts and /etc/inet/ipnodes.
Otherwise run sys-unconfig again and start over.

I just set up a wireless network using an airport express. How can you change the network name

How can you change the name of a wireless network set up with an airport express

Yes, you can. If you use the current AirPort Express, Apple says that you can connect up to 50 devices. Realistically, make that 25-30 or so before the speed really begins to drop.
Remember that you will have to reset the modem though, before you connect it to the AirPort Express as the modem "remembers" the settings for your computer.

How do I change my country configuration in my Adobe account?

Hi,
When I a couple of years ago registered my CS4 I must have accidently set up Switzerland as my country instead of Sweden.
When trying to edit my account I can more unless change everything but the country. I'm aiming to purchase Creative Cloud and I'm not keen on paying
in Swiss franc every month, my accountant would hate me;-)
How do I change this?
Regards,
Daniel

Hi Dabat,
Towards the bottom of the Adobe.com page you should see an option to change your geo, make sure that is set correctly before starting the purchase process. Creative Cloud payment works off Credit Card. If your Adobe ID was associated with an incorrect region you would want to contact Adobe customer service for help changing that.

How do I change the network password without a base station?

I do not have an airport base station. My roommate has a PC connected to a router via ethernet and I created a wireless network on the same router via airport. Now I've hopelessly forgotten the password and I can't figure out how to reset it or change it or whatever! Can anyone help me, please? I've searched the forums and have only found answers for those folks with the fancy airport base stations.

Hi,
The WLAN password could only be change on the router page you found and in order to get there, you need the administrator password.
If you never modify it, you could give a try by entering "Administrator" and leaving password blank which is usually the factory setting. If this not work, it will be necessary to reset your router to its factory setting.
I personnally do not know the Belkin routers. But here is the link to get your router manual:

How do i change my network proxy settings on iTunes?

Hi,
I've been using a certain proxy to connect to the iTunes store on my PC iTunes.

How do i reset these settings so i can enter the new proxy settings. iTunes keeps on telling me to check my network connection.
Thanks in advance.

Authorization
iTunes Store- Authorize or deauthorize your Mac or PC.
In iTunes you use the Authorize This Computer or De-authorize This Computer option under the Store menu in iTunes' menubar. For Windows use the ALT-S keys to access it. Or turn on Windows 7 and 8 iTunes menus: iTunes- Turning on iTunes menus in Windows 8 and 7.
Deauthorization
You can de-authorize individual computers, but only by using those computers. The only other option is to "de-authorize all" from your iTunes account.
1. Open iTunes on a computer
2. From the Store menu, select "View my Account..."
3. Sign in with your Apple ID and password.
4. Under "Computer Authorizations" select "De-authorize All".
5. Authorize each computer you still have, as you may require.
You may only do this once per year.
After you "de-authorize all" your authorized computers, re-authorize each one as required.
If you have de-authorized all computers and need to do it again, but your year has not elapsed, then contact: Apple - Support - iTunes - Contact Us.
For more information on authorization and de-authorization: iTunes Store- Authorize or deauthorize your Mac or PC.

How to handle change of relation with SAP

hi,
suppose i'm an employee of a SAP customer right now (meaning i have an S-ID), and then later on i'm employed by a different SAP customer, triggering a deactivation of my old S-ID, and the creation of a new S-ID, how would the transition of S-IDs be handled? would i find myself not able to login to my account (since naturally my email address would change too)?
or is my S-ID stuck with me for life?
honestly i wouldn't want this to happen (nor do i see this happening), but suppose it did, how would the powers that be handle this?
ryan.

hi Denis,
it depends what kind of data you're trying to delete:)
during the standard output (IDOC) of some documents
you can see a deletion indicator (action), there are also
some document which you can delete on the basis
of specific conditions - for example when somone
sets a rejection indicator in a document this might
mean that the document (or one of it's lines)
was deleted
so basically it depends what kind of data you want
to delete

How can I change my VPN configuration so that not everything goes through it?

So I generally connect my laptop through my WiFi connection, which is set as priority number 1. For connecting to certain servers at my office (I work remote) I need to VPN in. Now, I'd like to be able to stay connected to VPN without ALL my internet data going through it. My understanding of the network priority list was that it would attempt the higher connection and then go lower. But I have WiFi at the top of my list and VPN at the bottom, yet everything is going through the VPN. I know this because I did a traceroute and every URL I hit is going through my work servers. I disconnect VPN and try again, they go through the comcast DNS server.
So my previous understanding of the priority list was that it would try through the highest priority, and then only if that didn't work it through go through lower priorities in order. Is that wrong? Is there actually a way I can get it to do what I want? Thanks.

With VPN software installed on your Mac all connections to the net will go through that VPN. you have to shut the VPN down for your normal traffic to go directly out to the net. That is just how it works.
Let me add that is the point of a VPN. So everything done on the computer goes through a Virtual Private Network to your workplace. Otherwise your computer could expose the work network to malware you might get from the Net on your computer.

How do I change my network settings to active to update for my IPhone 4??

I am trying to update my IPhone 4, after it downloads the file and when it goes to update it says "Network connection timed Out" Make sure your network conditions are active and try again later. My network connections are active and my internet connection does not timed out during the process.
Does anyone know how to resolve this????
Thanks

Yes, and had you searched the forum before posting, you'd have had your answer already.
Turn off all antivirus and firewall programs before downloading.

The printer chosen is configured in the SD customizing, there are quite many options how to configure that.
> **I am not sure which parameter control the immediate print,how can i control PO print not immediately and I can choose own output device and printer ?**
You can find the settings in
- transaction SPRO
- SAP IMG
- Sales and Distribution
- Basic Functions
- Output Determination
Usually it's not a good idea to print locally, this is especially not possible when something is processed in the background.

How to handle Changes in the Structure of Outbound Message.

Hi Experts,
I have a File2RFC scenario where the Outbound Message fields are (for e.g,) ID,Name,Loc, and Status. The structure of the xml file which needs to be picked by sender file adapter is changing each time based on the data entered by the user. I am sure this will fail in IS with RuntimeException in Message-Mapping transformation Error. Is there anyway to handle this kind of situation.
Message Sample- 1 (Message Processed successfully as it contains all the 4 fields...)
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Send xmlns:ns0="http://File2File">
   <root>
      <ID>1234</VesselID>
      <Name>PIUSER</VesselName>
      <Loc>System A</Type>
      <Status>1</Status>
   </root>
</ns0:MT_Send>
Message Sample- 2 (Message Failed with Runtime Mapping Exception in IS...'Loc' is missing)
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Send xmlns:ns0="http://File2File">
   <root>
      <ID>5678</VesselID>
      <Name>SAPUSER</VesselName>
      <Status>2</Status>
   </root>
</ns0:MT_Send>

Hi Ravi,
Thanks for the reply. I think changing the cardinality will not solve this issue. Because the file which is being picked by Sender file Adapter is changing its structure everytime based upon the values entired by the user.
For example - In Message 1 User has entered all the 4 values...so the structure is full.
Message Sample- 1 (Message Processed successfully as it contains all the 4 fields...)
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Send xmlns:ns0="http://File2File">
<root>
<ID>1234</VesselID>
<Name>PIUSER</VesselName>
<Loc>System A</Type>
<Status>1</Status>
</root>
</ns0:MT_Send>
In Message 2 - user has entered only 3 values...Though I have kept Loc as 0 to Unbound it fails as there is no tag <LOC></Loc> here.
Message Sample- 2 (Message Failed with Runtime Mapping Exception in IS...'Loc' Tag is missing)
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Send xmlns:ns0="http://File2File">
<root>
<ID>5678</VesselID>
<Name>SAPUSER</VesselName>
<Status>2</Status>
</root>
</ns0:MT_Send>

How to handle change in RFC module inside webdynpro

Hi All!
I am developing a rather large webdynpro application. The development is a "work in progress" meaning that from time to time we find that there are requireemtns for additional fields in some of the tables / structures of the RFC module.
Normally what we do, when adding or deleting an attribute from a table/structure is:
Reimportmodel.
Delete Cotext.
Click Apply Template, and create new model binding using the template.
modify the method.
But are there other ways to handle reimports?
Because when we use table XXYY in 7 different RFC modules and then add/remove an attribute of tabel XXYY we have to delete and re-create 7 modelbidings + method = VERY VERY time consuming, and error prone - because all the views attached to our component contoller also has to be reimported.
Does anyone know a smarter / more convienient way to do this?
Inputs are highly appreciated!
Best regards,
Ronni Hostrup

Hi Again,
i guess i was a little to quick in my reply.
The method above i am afraid does not work.
What i did was:
the RFC module was changed (an extra field was added to a table of the rfc module)
reimported the model (on my DC containing the model)
re-deployed the model on the server.
opened the dc that uses the model and removed the model from used models.
-- no errors occoured. then i removed the use of the entire DC (removed it from used dc )
rebuilded the projcect, and alot of errors accoured.
add the model dc puplic part again, and added the model as used model.
rebuilded the project again - no errors.
in the context i, under input and output of the affected modelcontext i choose edit model binding ,and then chose the model type. and marked all of the fileds (i could see my ekstra field)
updated the ui that used the models.
deployed the archive, restarted the j2ee engine - just to be sure.
deployed the archive again, and nothing worked - ie. not a single entry in the entire table
so i guess i have to delete the model contex and then click the apply template to rebind and recreate alle my RFC modules again - since most of them use the same modified table
but thanks for the inputs. - lets hope that SAP one day realizes that this is not very clever made
best regards,
Ronni

How to handle Release transfer for Configuration objects in PI 7.1?

Hello Experts,
In my current project we are working on Release1 production bug fixing (JDBC to IDoc interface) and parallely on release2 enhancement (field addition, mapping changes) for the same object.
I have used release transfer to copy IR objects (mapping, etc) from SWCV 1.0 to SWCV 2.0 and started making Rel2 mapping changes in SWCV 2.0 IR objects. But, am not able to create the ID objects (receiver determination, interface determination, etc) for Rel2 SWCV objects. Even though I select interface from SWCV 2.0, it says object already exists.
Please suggest.
Thanks,
Raks.

Hi,
AFAIK ,SWC is not a part of the Key in identifying the receiver determination in the PI 7.1 also....
which means that no need to create the ID objects again...as said for the changes (sender channel and inbound interface structure...) only change will be in the ESR interface structure.. which will be used by the ID...provided the same namespace is used for the changed message type also....
Hope this clears you
Rajesh
