Improving install experience in IOS XR (ASR9K/CRS)

This time its a question to our customers:
If you insisted on keeping SMUs, SPs, Install rollback and the things you have gotten used to today, how would you change the install process to make it simpler, but still provide what we do now?
Or asked differently what do struggle with today when it comes to Installing/Upgrading Software and what would you like to see improved.
We want to hear your feedback. You can send a message too, please don't hold back..
Eddie.

Mathieu, inline:
>For example we were running 4.3.4 on our ASR9K and faced few bugs. Most of them were fixed in >SP3. While upgrading a router from 4.3.4 to SP3, we ran into a bug that completely crashed our >router. We had to turboboot everything. We raised a ticket with TAC and they told us we had to install >asr9k-px-4.3.4.CSCul58246.tar before upgrading to SP3. Unfortunately, this fix needs >asr9k->px->4.3.4.CSCug75299.tar and asr9k-px-4.3.4.CSCui94441.tar. This means to upgrade a >router from 4.3.4 to SP3, you actually need to reboot it 3 times!!! By optimizing as much as we can >this process, this means a maintenance of ~50min which is a lot of downtime for our customers!
Mathieu the SP Readme has been updated to include these per-requistes, so hopefully in the future it shouldn't be required. This process of pre-req smus for SP are not needed from 5.1.3 on.
>Why not releasing a 4.3.4-SP image each time your release a SP? At least providers could turboboot >it already patched?
Turboboot is the last thing we want you guys to do, its slow and painful, turboboot should rarely be used.
>Concerning turboboot, the transfert speed thru an integrated management port is catastrophic. We >can't specify a large block size to speed up things so even if we have a TFTP directly connected to >the port, transfers are way too slow. A good way would be to be able to transfer files with HTTP / FTP >during a turboboot.
We don't have a TCP stack in ROMMON and we don't plan to support it. We will support things like ONIE and IPXE in the future.
>Then if transfers are done in a fast & efficient way, we could save time by directly sending an >uncompressed image over the network instead of waiting for the router to decompress the archive.
I like the uncompressed image idea, we are exploring that.
Thanks for the feedback and we'll keep you posted.

Error in installing Experience Manager.

Hi all,
I have installed -
1)MDEX
2)Platform Services
3)CAS
4)Document Converter.
5)Deployment Template.
6)Oracle Endeca Guided Search 2.1.2 for Microsoft Windows x64 (64-bit)      V31161-01
Everything is installed in a single local machine.The Endeca Reference Application is running fine also.
But when I am trying to install Experience manager -
Oracle Endeca Experience Manager 2.1.2 for Microsoft Windows x64 (64-bit)-
xmgrworkbench_2.1.2.618087_x86_64pc-win32 -
it is showing the following error.
"All other Workbench installations must be uninstall before installing Workbench.
Please uninstall all other versions of Workbench before running this installer."
My question is -
There is two components in https://edelivery.oracle.com-
a)Oracle Endeca Experience Manager 2.1.2 for Microsoft Windows x64 (64-bit)      V31162-01      80M
b)Oracle Endeca Experience Manager Extensions 2.1.2 for Generic Platform      V31169-01      71M
Which one I have use to avail the experience manager's functionality (Template creation etcs ).
Or I have to use both the versions ?
What are the components need to be installed to work perfectly with experience manager .?
Regards,
Hoque

Hi Hoque. I know it is a bit confusing and we are working to simplify things in future releases, but you will want to install
either
Oracle Endeca Guided Search 2.1.2
or
Oracle Endeca Experience Manager 2.1.2
but you do not need both.
Oracle Experience Manager includes Endeca Workbench and the Experience Manager tool and is the option you'll use when the deployment includes a license for Oracle Endeca Experience Manager. The Oracle Endeca Guided Search package includes Endeca Workbench and the Rule Manager tool and will be used for deployments that do not include Experience Manager.
If you're starting a new project, I recommend starting with 3.1 instead.

Hi everyone! I tried to install the new iOs 7 on my iphone 4, but it wasn't completed (showing error 4005). Now, my iphone is stuck on the itunes' logo with the usb cord, and I can't use my phone. And itunes doesn't detect my iphone when I connect it on my computer, so I can't put it in recovery mode or someting like that... What can I do?? I tried everything they tell me to do in the apple support but nothing seems to work. Thank you!

No problem, glad to help!
Update: my PC USB hub was connected to a USB 3 port, I connected the 30 pin cable directly to my PC, And the restore worked just fine. Restored phone from iCloud backup and seems to be working fine.

You can use the stereo input on the Bose.

Hi,
don´t be worry, this would not be a problem.
You have to take the same Aplle ID on both devices, then you can sync them via iTunes by using all universal apps on each device, create playlists, albums and all the things you need and sync it, no problem...

Bonjour Pierre,
there seems to be a bug in iOS5 with regards to Bluetooth. THere are a lot of threads in here on this. We're all waiting for Apple to fix this...

Iphone 4s - try to install latest update ios 7.1.2 - unable to install update - an error occured when installing 7.1.2

iphone 4s - trying to install latest update ios 7.1.2 - takes long time to verify and then i get unable to install update - an error occured when installing 7.1.2?

First it would help if you identified the error. That might assist you in knowing what to do next. See this support document for help with error codes when unable to update or restore the iPhone. Resolve iOS update and restore errors
Then you can also see this support document for trouble with updating the device. If you can't update or restore your iOS device

I've installed the latest ios 6 however, the sound has gone from all programs , music , youtube any help
iPhone 4, iOS 6
The ringtones are working but all other sounds are not working please help

I had this problem on my iPod Touch 4g. Just press the home and sleep button. Wait and it will give an iTunes and cable logo. Now you can put in DFU mode (Hold Sleep and Home button 10 seconds and then release the power button kand keep pressing on the home button.) Now you will be able to restore it in iTunes.
If you didn't sell it in al this time

Is installing mountian lion the same as doing a clean install of an iOS

is installing mountain lion the same as doing a clean install of an ios?

Haven't a clue what an ios is, but reinstalling SL, Lion, or ML replaces all OS components and the basic Apple apps, such as TextEdit, Safari, Mail, and Terminal. What it doesn't do is touch any user data, settings, or other apps.

Improvements for IWork for iOS

I write to suggest improving your IWork for ios application.
The applications are very good, but lacks some important features that would help iPad -Iphone users to work better.
These absences are:
NUMBERS:
- filters
- sort by more criteria
- categories
- better use when a keyboard is attached in the iphone or iPad, it is no neccesary that the virtual keyboard appears all the time, please, let the user choose if he considers it is neccesary
- Landscape view in iphone
- Support for more functions
- Capacity to open bigger spreadsheets
I suggest to checo out the Polaris Office application, this one has some functions that are lacking in Numbers.
PAGES:
Please, a better way to insert: page jump, tab, etc. Maybe a button in the Toolbar.
IWORK FOR IPHONE: Besides the requirements listed above: a undo-redo button, because, it is very unconfortable to the user, shake his iphone when he has to undo or redo a lot of actions.
Thanks And
Best regards

Arch install experience / install CD uses devfs path names

Hey, all I'm new to the forums, very happy arch user. I can't remember how I found arch, it must've been fate. I did my share of distro hopping. Actually, I plunged into the deep end with my first Linux install by choosing to run Gentoo. To their credit I was able to get it installed by relying on their solid documentation, even though I was an absolute novice at the time. Still I had to leave Gentoo because on the whole I'm too impatient to compile every single program from source.
I then drifted to Mandrake for a short time, and then Fedora for a longer time. I became intimately familiar with dependency hell, and tracking down specific versions of libraries. I like using a few bleeding edge programs that are compiled out of CVS or SVN, and I found that it was a nightmare satisfying dependencies and dealing with package conflcts. I also ran Ubuntu for literally about 5 minutes. I won't get into why that lasted such a short time.
I was on irc the the other day in a dev channel for bmpx, attempting to get the newest version of bmpx to run (still am). One of the devs asked me if I was running FC4 (Fedora Core 4). My response:
Me: "I don't think I'd have a snowball's chance in hell of getting this working under FC."
Dev: "I'm running FC5."
I had to swallow my words. Here I am, a proud arch user with a seg faulting bmpx while the dev is running it on FC. Moral of the story: that guy must be a magician. That or FC is much more up to date now. Still, nothing could convince me to abandon pacman and go back to RPMs. Pacman is a Godsend. The whole ABS system is beautiful.
I just recently reinstalled a fresh version of arch after something of a hiatus. A while ago I borked my system (I had an ugly situation with my partition table, among other things) and I didn't get around to resurrecting my install for a while.
Now this was before Xorg7, and uDev, and ArchCK's move to initramfs. Obviously I was upgrading after those things were introduced. To further enrich this unhealthy mix, I have an ATI Radeon 9800, 2 ethernet cards (onboard), and 2 sound cards (PCI, and onboard). It might go without saying that I had a rocky install experience. It was like putting together a jigsaw puzzle blindfolded. Then I came to the Arch site and read about all the changes. Even then it was a messy experience, what with uDev simultaneously loading modules and whatnot (turns out that this can be a problem on systems with multiple soundcards or NICs). Finally after a boatload of troubleshooting, and much reading of the Wiki and the forum, I got everything setup. Queue angelic choir: I even got 3d acceleration via fglrx to work thanks to Iphitus's drivers, and posts in the forum by Cerebral.
So I'm once again a happy arch user, but I'm glad it wasn't my first arch install. My first install was ultra smooth by comparison.
If you're still reading you're probably wondering if I'm going to make a point. Well since, I'm new to the forum I figured I'd give a little background for anyone interested, and a little hope to to anyone wrestling with their install.
Actually I do have a question which I alluded to in the subject of this post. I did an FTP install from a CD I downloaded several months ago.
The Grub installer gives this message:
"Arch Linux supports two /dev device systems, DevFS and uDev. You can select the one you want by modifying your bootloader's configuration."
Obviously now only uDev is supported so that message is outdated. Plus the auto-generated fstab and menu.lst use the DevFS device paths by default.
So my question is do the newer install CDs generate fstab and bootloader config files using the uDev naming scheme or do they still default to DevFS? I realize I was using an older CD, but it was confusing not knowing that DevFS had been completely abandoned.
Also there should be an initrd line added to the autogenerated bootloader config (can't remember if it's there or not).
Maybe these issues have already been addressed in newer install CDs. Hopefully they have for the sake of first-time installers.
Whew okay I'm done, thanks guys.

jesus franco wrote:It seems you have 0.7 even though 0.7.1 fixes all those devfs,initrd issues.
Yea I think I do have the 0.7 CD. I just do FTP installs anyway so I didn't bother downloading a new CD. I was kinda guessing that the newer CD probably sorts out the uDev / DevFS issue but I wasn't sure. Nothing to worry about then!

I've installed the latest ios 6 however, the sound has gone from all programs , music , youtube any help

Until you have tried Maps, Music, etc. first hand, I wouldn't formulate negative opinions about them. And updates, if performed correctly, do not erase data.
I presume that last time you updated through iTunes. This time, update over Wi-Fi by going to Settings > General > Software Update.

HT4623 how to install siri in IOS 6

Firefox automatically sends some data to mozilla so that we can improve your experience.

i tried asking this in a similar topic and got no response and marked as answered so ill ask it again. i already had 'Enable Telemetry' and 'Enable Crash Reporter' disabled but i still got the popup. i'm not sure why firefox is saying it's automatically sending mozilla data when both options are disabled.
it used to say
will you help improve mozilla firefox by sending information about performance, hardware, usage and customizations to mozilla?
but that was changed to
firefox automatically sends some data to mozilla so that we can improve your experience.
this makes me think firefox is still sending data regardless. so as long as both of those options are disabled firefox is not sending ANY info about me? if that's the case mozilla really needs to update the message. privacy policies are usually so vague and shadily written by lawyers that they are just about useless.

Firefox 20 has a new message to prompt you to check your settings. This is in preparation for a future feature called health reporting, but currently the only categories are the same old ones: telemetry and crash data.
