Upgrade and Redundancy
Hi Expert,
We have a 3 tire SAP System (DEV,QAS and PRD),
we under Windows 2003 and SQl 2005 Environment,
We are upgrade our DEV & QAS Environment to Windows 2012 and SQL 2012,
We now plan to Upgrade our Production server also to the same (Win,SQL) 2012,
Also we want to make a redundancy server to Our production serve as (active to passive Or active to active) in anticipation of any database corruption because we face this problem in the first of this year.
What's the correct solution we can do it?
what's available material to help me to implement this solution?
what's the type of replication we can do?
How we can make a tow sap system work in the same DB on time?
Are anther sap instance on the new server will take the same name or not?
Summary i want to find a solution for no down time if database corrupted suddenly.

Hi Said,
Due to Electricity problem our database on SAN is corrupted,
Because of this we want a solution for completely separated server and with separated DB with minimum Down Time .
You can create manual DR setup within co-location of Production system.
Here you manually sync up DR system with data and logs. This can be used incase your Primary goes down . This DR system will have same hostname ( virtual hostname) so that users need not change any entry in SAPlogon pad while using DR system.
You may also look for other alternate solution which is based on SAN replication. Check with respective hardware vendor for the same.
Hope this helps

Upgrading ACE , redundant active-active context
Hi,
We have 2 ACE's running in our network, and we would like to upgrade the ACE software.
To minimize any disruption to existing network traffic during a software upgrade or downgrade, deploy your ACE modules in a redundant configuration. For details about redundancy, see Chapter 7, Configuring Redundant ACE Modules. The following steps provide an overview on upgrading a redundant configuration used in conjunction with the procedures in this appendix:
1. Upgrade the active module first.
2. Reboot the active ACE after the software installation. When you reboot the active ACE, it fails over to the standby module and existing traffic continues without interruption.
3. Upgrade the new active module.
4. Reload the active ACE after the redundant module is up and the high availability (HA) state is hot. A similar failover occurs when you reboot this ACE and once again the existing traffic continues. The original active ACE is active once again.
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A1/configuration/administration/guide/upgrade.html
This section describes the methods and CLI commands that you can use to troubleshoot redundancy issues in your ACE.
1. Ensure that the software versions and licenses installed in the two ACEs are identical. A software or license mismatch may generate the following syslog message:
%ACE-1-727006: HA: Peer is incompatible due to error str. Cannot be Redundant.
http://docwiki.cisco.com/wiki/Cisco_Application_Control_Engine_(ACE)_Module_Troubleshooting_Guide,_Release_A2(x)_--_Troubleshooting_Redundancy
Following those step, is there any problem would happen after step 2 , having a different software version on the first and second module?
also on step 4 ' Reload the active ACE after the redundant module is up and the high availability (HA) state is hot. ' , is that possible with both module use a different software version ?Hi,
When you upgrade or downgrade the ACE software in a redundant configuration with different software versions, the STANDBY_WARM and WARM_COMPATIBLE states allow the configuration and state synchronization process between the peers to continue on a best-effort basis. This basis allows the active ACE to synchronize configuration and state information with the standby even though the standby may not recognize or understand the CLI commands or state information.
In the STANDBY_WARM state, as with the STANDBY_HOT state, configuration mode is disabled on the standby ACE and configuration and state synchronization continues. A failover from the active to the standby based on priorities and preempt can still occur while the standby is in the STANDBY_WARM state. However, while stateful failover is possible for a WARM standby, it is not guaranteed. In general, modules should be allowed to remain in this state only for a short period of time.
http://docwiki.cisco.com/wiki/Cisco_Application_Control_Engine_%28ACE%29_Module_Troubleshooting_Guide,_Release_A2%28x%29_--_Troubleshooting_Redundancy#About_WARM_COMPATIBLE_and_STANDBY_WARM

I have just updated to iOS7, no icon for browser, was using Safari, how do I get it back and can I reverse the upgrade and go back to iOS6? Thanks to you from the UnTechie
The icon for Safari has probably moved to make room for new apps. Scroll the Home screen to look for it.
You cannot reverse the upgrade. -
What is difference between Startup upgrade and startup migration.
what is difference between Startup upgrade and startup migration.
I am having the metalink note.
STARTUP MIGRATE was introduced in 9.2 as a mechanism to be sure that most everything that needs to be done to run an upgrade script or a patch script is done automatically. In the past, customers were expected to adjust certain initialization parameters prior to beginning an upgrade or applying a a patch,
but most of this is now done automatically by STARTUP MIGRATE.
When a customer starts a database in MIGRATE mode, the following ALTER SYSTEM
commands will be set automatically:
But i am not sure what exactly the meaning by startup upgrade.

Can someone help me figure out something because I'm sure their is a way I can and husband won't upgrade me and I got free upgrade and can't even get because he's cheap it's sad Hugh
What iPhone do you have? You can check in settings>>general>> about.
If you have a 3G you cannot update beyond iOS 4.2.1. The 3G is over 4 years old an was discontinued over 2 1/2 years ago. You need the latest ios to run the latest versions of some apps. If you have a 3GS you can update.
If your phone is not responding, reset it by pressing and holding down both the home button ad lock/ sleep button simultaneously until the Apple logo appears. -
Firefox has suddenly gone wrong. I was successfully running both Firefox and Internet Explorer 8 on Windows 7. My laptop is new and has plenty of RAM and HDD. I auto-accept upgrades including the most recent Firefox upgrade and the suggested upgrade to Adobe Flash 10.1. But after this, Firefox stopped working and does not work when I re-load Firefox 3.6. Also IE8 now works very slowly and does not locate major websites like Microsoft without a 'can't find the website message' and having to pressing Return a second time. When I do get to the Mozilla website and click on the button to try to download Firefox 3.6.6, I get this message "Oops! Internet Explorer could not find mozilla3.snt.utwente.nl". Can you help with what has gone wrong? As it stands, I can't use Firefox at all. Note: because Firefox did not work after the upgrade, I've downloaded the IE8 version of the Adobe Flash 10.1. What I really want is to be able to use both Firefox and IE8. But is this possible if they use different versions of Adobe Flash?

After upgrading to Ffx 3.6.6, the program asks you to upgrade to Flash Player Plugin 10.1. I download and installed 10.1 only to find videos weren't loading.
In my case, the problem is the previous installation of Flash Player (9.0.47) was somehow messing things up. To fix this, because I already had Flash plugin 10.1 installed I had to uninstall 10.1 using the uninstaller from adobe and then manually remove any files related the old flash player plugin 9.0.47
Here is a run-down of my process:
0. To check if you have a previous installation of the Flash Plugin lurking around, in Firefox go to Tools -> Add-ons -> Plugins (tab). At this point you may seen both Flash plugins.
1. Proceed to uninstall Flash Plugin 10.1. Adobe provides an uninstaller here: http://kb2.adobe.com/cps/141/tn_14157.html
( you have to make sure you have nothing running when you execute the installer).
2. On my Mac (sorry I don't know what it is in Windows) I searched the hard drive for any files/folders with "Shockwave". I found a folder called "Shockwave 10". It wasn't removed by Adobe's uninstaller. For safety I deleted it and then emptied the trash.
3. I then went to My HD -> Library -> Internet Plugins.
Remove the file and folder named "Flash player.old"
4. Restarted; ran the Adobe Flash Player 10.1 installer. Restarted again.
5. Opened up ffx and double checked the plugins list (see step 1). Version 10.1 is installed and available. Went to problem sites to test it out and Success!
Hope this helps. -
Help with simple OS upgrade and backup questions for a dumb old previous PC user...?
Ok...have mercy on me, please...
I am not completely dumb, I know typical board etiquette, and I have searched for various answers (and found many)...but I just want to confirm my personal "research" and get all of this clear up before I proceed with this insanity. I know I could probably search more, but this is taking hours, because of all my various questions, one leads to 10 more...
I have an iMac with Mac OS X Version 10.5.8 (which, though not mentioned anywhere?...is apparently "Leopard", right? Told you I was dumb...)
Processor: 3.06 GHz Intel Core 2 Duo
Memory: 2 GB 800 MHz DDR2 SDRAM
My main goal: install an app that was in the Mac App store.
However, with Leopard, I can't access the Mac App store with Leopard, apparently.
I click on the Mac App store, and up pops up a Lion advertisement...telling me I should upgrade. Ok, fine...probably a good idea, anyway...
But how do you upgrade to Lion? Apparently through the Mac App store!
The web-redirects on the Apple site are amusing...taking me on an endless cycle...purchase Lion in the app store...click..."you need to upgrade to Lion"...OK...click..."you need Lion at the app store"...OK...click..."you need to upgrade to Lion to get to the app store"....etc.
OK...fine...google searches...ahh, I need to upgrade to Snow Leopard first, apparently! Yes?
(Maybe the Apple redirects should detect that I have Leopard, and direct me to a screen that explains that I must upgrade to Snow Leopard...and then Lion! Do you hear that, Apple? Thanks.)
Anyway...so here's my plan:
1) Upgrade to Snow Leopard
2) Access the Mac app store
3) Upgrade to Lion
Question A: With my iMac (specs above), is it really advisable for me to do this? Can my computer really handle Lion? It seems I barely meet the minimum with my intel core 2 Duo and 2 GB ram...yes? Is this a dumb idea, even if "OK"? I know that "minimum requirements" on a PC often meant: "Well, it will work...but it will be slower than a snail and crash if you run 5 programs at the same time" (which I usually do...) I don't want to upgrade if the "minimum" is really not enough.
Question B: If the answer to A is "not a good idea", then do I just need a new computer (i.e. better processor)? Or do I need more Ram? And can I add Ram to this computer, and is it relatively easy? I have added Ram to PCs tons of times, and you always have to determine type of Ram for your board, make sure they "match", or whatever, and then open up the machine and install. Kind of a pain, but once I have the "right" type of Ram, opening the CPU and installing is within my abilities. Will it be harder for a Mac?

When upgrading an OS on a Windows, you pretty much format the harddrive and start all over. Back in the day I was a PC user, there wasn't really a "great" way to back up programs and files, so this was a nightmare. You could NOT just back-up software. You typically had to re-purchase and install it all from scratch. Is this the same with Macs? Furthermore, personal files were scattered all over the hard-drive for the individual software...so trying to back all that up to get it back on the new system = nightmare! I hate PCs.
Anyway...so, my iMac has Time Machine. I am pretty ignorant about this, and based on my previous PC backup program nightmares, I have a distrust for it...and don't really understand how it works. But in any event, my external drive crashed a few months ago, and I haven't replaced it, yet. So, I am replacing it soon and will get Time Machine back up and running...setting it up again, etc...leading to question C...
Question C: When upgrading from Leopard to Snow Leopard to Lion, what is the best way to ensure I keep all my programs and files. My wife and I both access the computer, so two user accounts. Does Time Machine really do a good job backing up everything and all things? Is it just a matter of upgrade to Snow Leopard...then immediately to Lion...and then some sort of "Restore" from Time Machine? Anything for me to "watch out for"...or to do when I buy a new external hard-drive and setup up Time Machine for the first time on it, in order to make this work well? Will I have to re-install all the various applications I have installed on this thing? (like with PCs?)

Apple has discontinued support for 10.5, it's a plaque of our platform that Apple only supports the last two operating systems in circulation.
Where as on Windows you can run the same OS version for 10 years and get updates free (if not stolen), on a Mac we get one year, two tops now and if you don't upgrade and break all your third party software and hardware drivers in the process, then your denied security updates.
On top of that, the OS X upgrades tend to break your older hardware too, or slow it down so much that it drives you to want to buy newer hardware.
It's funny Apple places the AppStore on your OS X version along with iTunes and Safari updates, but then doens't supply necessary security updates, your machine may be compromised and here you enter vital credit card info, banking etc. thinking you have a secure machine.
My advice, since that's a 10.5 era Mac, is to upgrade to 10.6.3 via this disk, then use Software Update until clear. You'll get security updates and your present installed 10.5 software will work in 10.6 using Rosetta.
http://store.apple.com/us/product/MC573Z/A
Rosetta is not avaialble in 10.7 so it could be a lot of your software will no longer function
http://roaringapps.com/apps:table
I don't see the sense in you buying all new software for a machine that's at it's end of life stage.
You can buy software in the AppStore with 10.6.
Question A: With my iMac (specs above), is it really advisable for me to do this? Can my computer really handle Lion? It seems I barely meet the minimum with my intel core 2 Duo and 2 GB ram...yes?
You will need to buy 4GB of RAM to run Lion well, the 2GB is just a bare minimum, and your processor is a bit dated.
Lion 10.7 is certainly slower than Snow Leopard 10.6, in fact so many wanted to go back to Snow Leopard and one of the resons was Lion was slow.
So I wrote a User Tip, here, but the Tips were implemented only recently.

RAM is easy, you can buy it at Otherworld Computing or Crucial.com and install it yourself, there is a little door under the monitor.

Mac'soperaing system is seperate, it can be replaced or upgraded indepentantly of programs or user accounts on the machine.
There are some programs that install a kernel extension file at boot into OS X, those get knocked out, but those can be replaced with a new install of the software.
You should always backup your users files as those can't be repalced.

Question C: When upgrading from Leopard to Snow Leopard to Lion, what is the best way to ensure I keep all my programs and files.
OS X upgrades dont' affect User accounts but they can have a affect on programs installed, which most of your 10.5 programs likely will no longer work in 10.7
However they will (with a slight update) work in 10.6 just like before.
You need to backup regardless, I suggest a manual backup of users files to a storage drive, a 10.5 clone on another drive, the your ready to upgrade to 10.6
10.5 to 10.6 upgrade is rather painless, also 10.6 gives accelerated video drivers, so your machine will appear faster.
However once you install 10.7, you will slow down.
Does Time Machine really do a good job backing up everything and all things?
No, you shouldn't rely upon TM, have a multiple backup stragedy, TM files are hard to access directly.
Is it just a matter of upgrade to Snow Leopard...then immediately to Lion...and then some sort of "Restore" from Time Machine?
No need to restore, OS X upgrades and leaves everything else in place, just some programs (with 10.6) or a lot (with 10.7) when you try to launch them they will fail.
Also when you connect TM it will do a substancial change to reflect the new boot drive.
If you were using TM as a "storage drive" thinking you can use the archived versions later, that wil change upon the new OS X upgrade.
But in any event, my external drive crashed a few months ago, and I haven't replaced it, yet. So, I am replacing it soon and will get Time Machine back up and running...setting it up again, etc...leading to question C..
You need not only TM drive, but a bootable clone and user files on a storage drive.
Most commonly used backup methods explained
Will I have to re-install all the various applications I have installed on this thing? (like with PCs?)
No, depending upon what OS X version you stop at depends how many programs no longer work.
You will have to buy a lot of new or upgrade versions with 10.7, not so with 10.6 only updates mostly because of Rosetta on 10.6 and not on 10.7
My opinion, since that machine is a bit dated, is to upgrade to 10.6, Software update to 10.6.8, and stay there.
Later on 10.8 is being released after this summer, you may want to consider getting a new machine with 10.8 a few months later to ensure all the bugs are worked out of it.
Your not a comptuer savvy person, you like most Apple users expect your machine to "just work" I think going to 10.7 will be a bad experience for you.
10.6.8 will server your needs until 10.8 is released and on new hardware where Apple will hold your hand for free for three months, 3 years with AppleCare.
Your not a "OS X upgrader type of a person" and Apple needs to get of thier collective assets and pay better attention to it's most common users. -
Memory Upgrade and How do I add Bluetooth to S10-3
Hi,
Newbie here, just got my S10-3 last week and love it. I have upgrade to Windows 7 Pro and would like to increase the memory and add internal Bluetooth if possible. What type of memory card do I need to go to 2M? Lowest cost and brand/model number would be great information if you can provide it. Do you think it's possible to add Bluetooth internally? I know I can add using USB external, but would really like to keep it internal and keep all three USB ports free for other devices.
Thanks Much!!!

I'm trying to install Adobe Photoshop CS3 on a new ASUS ASM11BB001O computer equipped with 64-bit Windows 7. I use a "bundle" approach, first loading Photoshop 6, then upgrading with CS upgrade and then CS3 upgrade. The installation goes smoothly until I add PS CS, and then it balks at the "accept" Adobe conditions screen. I have two other (Gateway) computers with Windows 7, 64-bit, on both of which the PS-6, CS-CS3 pathway worked fine. Any thoughts on how to get this working? Thanks
If your goal is to install and activate CS5 there is no need to install anything preceding it. You will only need to have the serial number from the preceding version that you upgrade from (CS3 I guess).

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Windows 7 upgrade and existing Windows Vista Home Premium license...?
Hi,
As per Lenovo's scheme, after applying for Windows 7 64 bit upgrade and upon receiving the installer DVD, do I need to compulsorily install it?
Does "upgrade" here really mean that the day when the Windows 7 DVD was issued on my name, my existing Windows Vista Home Premium 64 bit license will become Invalid or get expired? Or I can continue using my existing installed Windows Vista on my Laptop and install the received copy of Windows 7 as and when I want or even don't install it on my Laptop, if happy using existing Windows Vista only?
