Reinstall Xserve OS X Server 10.4, minimal downtime

Hi,
Ever since a powercut 2 weeks ago now we have had constant minor problems with our xserve, mainly with the file sharing and a couple of kernal crash's.
I am going to re-install the server but i want to keep the downtime to an absolute minimum. Our Xserve is a G4, is it possible to setup and install OS X Server 10.4 to an external firewire on an Imac G5 then copy across onto the Xserve when complete? Will this have any issues with being installed on a G5 processor then coppied onto a G4?
Any Issues with setting up OS X Server on an Imac?
Regards

I think I would be tempted to do it the other way around...
Clone the existing system to the external, test it, and then run this whilst doing the new install onto the 'real' server. More downtime for the 'real' server but no later concerns about compatibilities.

Migrate entire database to ASM on another server via RMAN minimal downtime

Hi
I was looking for a procedure to migrate non ASM production databases to ASM via RMAN on a separate server with minimal downtime (backup as copy/switch database to copy technique). We have TDPO for tape backup and I normally rman clone test databases between servers but this involves too much downtime for production. The procedure in the ASM Admin Guide (Chapter 8) assumes the databases are on the same server.
Thanks

Tom CullenDear Tom. Why you think you'll have downtime in the production database? The database will be running while the clone will be processing. Check the following link:

Migrating SQL Server Published databases with minimal downtime

All,
I have a requirement in which databases in Server A has to be mirated to Server B. Server A has two databases in Merge replication and one with Transactional replication. Server A act as the distributor itself.
My question is how can I migrate all these production databases which are also publishers to new sever B with minimal downtime, and with out breaking replication.
I read that if the Server B is renamed as Server A then replication will continue with out any errors.Please suggest how to migrate the publisher to Server B with minimal downtime.
Also I would like to know if the replication is Server A->Server C->Server D, then if I can migrate Server A to Server B with out dropping replication, will it affect the replication setup from Server C to Server D. Does it cause any replication errors.
Thanks in advance!

Just to throw some thoughts out there.
It sounds like the "blocker" in the overall migration strategy is the Distribution database and the fact that it is local to a Publisher.
Once you have migrated the Distributor, the remainder of the problem
is more straightforward, using solutions such as Database Mirroring to failover to a new server with minimal downtime for example.
If I were performing this migration project, I would agree with the business that there was to be a
short replication service interruption whilst we migrated to a new Distribution database/server. I would also apply Hillary's recommendation to use the opportunity to split-out the Distribution database to a dedicated server.
Using this approach, you could build and configure the new Distribution database before the migration "cut over" phase. The cut-over would require that you Drop the replication topology and re-create it, using the new Distributor DB/Server. You can script
ALL the steps required for this ahead of time, resulting in the actual cut-over to the new Distributor being completed in a couple of minutes max (the database involved are already in Synch).
Once done, you can proceed ahead with the remainder of the migration.
Overall this is not a trivial project you have on your hands and in my opinion you absolutely must perform the process in a test environment before attempting to do so in Production.
Good luck.

Reinstalling OS X Tiger Server on XServe doesn't start...

We bought an XServe some 6 months ago now hoping that it could solve the unique problem we have. We're a small organisation with only a few members in the tech team - and we're constantly busy trying to develop and support our own product. We wanted a server solution to handle the standard services (DHCP, DNS, printing, etc...) that wasn't Windows-based. But there's only one chap in the organisation with full-on *nix skills. The other techs are relative *nix noobs.
So, the XServe and Tiger Server presented a compelling answer: a solution that provided all the power, robustness and scaleability of *nix server services, but with Apple's great UI for managing the services, with little hardcore server knowledge. Basically, it had to stay up, work consistently and be quick and very simply to administer for someone with little specific server config knowledge.
I suppose the XServe has served this purpose, but we're getting consistent problems with SMB file permissions, Windows interactions and issues with permissions on AFP file shares.
I think this has to do with my initial install of Tiger Server. I don't think the DNS and the Open Directory were set up properly, and I think this could be the root of all the file permission problems we're having. Therefore, we decided to backup and wipe the machine and start again.
So, I've got a very useful install guide from AFP548 that talks me through getting DNS working first, then setting up the Open Directory, etc...
HOWEVER
I can't get OS X Server to install. I've got the server DVD in the drive of the XServer, been through the process of putting it into 'light 1' mode using the buttons on the front of the XServe (so it boots from CD), and I'm using the Server Assistant from my Powerbook across a wired network.
I can go through the server assistant process as far as the install starting, but then I'm just left with a screen that says 'Installing...' and 'Installing Mac OS X Server on volume <Server HD>' and an empty progress bar. It just seems to hang and nothing happens.
I've tried:
- disk utility to check the disk for issues (nothing reported)
- booting the Xserve in firewire target mode and installing from my laptop (installer gets to the same place 'preparing hard disk' and gets no further)
- using disk utility on another laptop to erase the XServe's HD first, with the XServe in FW target disk mode (disk utility hangs when I click the 'erase' button).
So, I'm a bit stuck chap and chapesses. Everything points to a problem with the disk somehow (although it would have to be something that disk utility couldn't pick up), but I'm damned if I know what it is!
Any help would be much appreciated.

Have you a large hammer?
Just kidding, but I do think that you are on to something with it rebooting into the old OS just like nothing happened.
Unfortunately I have never actually encountered this so I am just tossing out suggestions. It sounds to me that you have already covered most of the bases that I would/could suggest.
Have you checked this manual http://manuals.info.apple.com/en/MacOS_X_Server_v10.4_GettingStarted.pdf
I know it is basic but perhaps an answer is in there. I wish I could be of more help but I still haven't got that pony either ;>)
Luck and keep us posted.

Xserve running Windows Server in a VM

Hi Guys,
We're looking to completely replace 4 servers, 2 are windows servers and the 2 are linux servers. We require to keep running those windows services for clients for now. Can Xserve run Windows Server in a VM properly?

I don't know why any small shop would buy a Windows box to run Windows.
It can be done better on the Mac with virtualization.
Read this link:
http://discussions.apple.com/thread.jspa?threadID=2417389&start=0&tstart=45
I'm 145 days of uptime with a 2008 Xserve 2x3.0GHz/12GB/3x1TB/10.6.3/Parallels 5.x running four W2K3 VM's and one NT4 VM. The setup is 2x1TB software RAID-1 in Bay 2/3 with a third 1x1TB in Bay 1, and a 1TB 2.5" USB drive hanging off the back. Utilization with 10 clients is <10%. Yawn.
Scheduled SuperDuper flings the Bay2/3 1TB RAID over to the internal 1TB in Bay 1 and the USB at night giving my a 1 day stale backup of the running VM's.
I can pull the USB out, plug it into my 15" i7, double click on the VM's and run the whole office.
The Parallels Transporter app can often be used to pull your entire server over into the virtual environment on the Mac, so your clients don't even know anything happened.
You will need legit/licensed/bonafide Windows with keys to do this, as Windows will recognize that the hardware has changed and want to be re-activated.
Get Parallels, dump your Windows boxes and don't look back.
If this is your first Xserve though, be prepared.
It's loud and hot.

Is there are way to reinstall task scheduler on server 2008 r2?

I have a server 2008 r2 and the backups are not running so I checked the task scheduler and there were corrupted task images. I then repaired them. Now when I schedule backup in the server manager, it always hangs at scheduling backups.
I've run sfc /scannow but no positive effect. I've searched if there is a way reinstall task scheduler on server 2008 r2?
I'm planning on re-installing .NET 4.0. Will it resolve the problem?

Hi Benaro,
Re-install .NET 4.0 may not help on this issue.
Here are some common steps to troubleshoot Schedule Task issues. Please try them first:
http://blogs.technet.com/b/askperf/archive/2009/04/13/tsk-scheduled-task-does-not-run.aspx
If issue still exists, please try to delete all manually created tasks and as the article said, try a simple task like start notepad.exe to see if schedule task is actually working or not.

Intel Xserve with Leopard Server 10.5.5 won't let me in via login

A power outage appears to have created some issues with my intel Xserve, running Leopard server 10.5.5
The System identifier light was blinking, so I booted up from the Leopard disk and found out that my mirrored internal array needed to be rebuilt. No problem, 4 hours later, I repair permissions on the mirrored internal array, everything gets "repaired". Change bootup disk to the internal 10.5.5 mirrored array and reboot. System Identifier light stopped blinking, things were looking good.
The login screen comes up and when I put in the admin username and password, the screen does the shake of the wrong login.
What's weird is, on my laptop I can use Server Admin, Workgroup Manager, and the screen sharing for the server....with the admin username and password.
So, I figure, perhaps the mirror rebuild requires me to reset the admin password. So, boot back up from the Leopard Server install DVD, run the password utility. and reset the main account password.
I change the boot drive back to the internal mirror, same thing. I'm stuck. I can't get past the login screen on the actually server....or via the screen sharing...and Server Monitor appears to be stuck at 'waiting for response'. I can, again, use Server Admin and Workgroup Manager on my laptop and make changes to the X server software....but I can't log into the X serve.
My webpage, wiki, etc....are all serving fine. But, I'd like to be able to figure out what I'm doing wrong...log back in and run super duper, etc.
Help...please...

Spent all day with apple support. They said it sounded like the LADP database was corrupted. They had me try to login as root, via an opendir account, etc. No luck.
So, they suggested I do a fresh install of the Leopard server on an external drive. Did that. They then suggested I use my laptop and the workgroup manager app to log in to the xserver, export users, groups and computers....and to copy over the library/collaboration folder to the external "clean install" of Leopard server.
Did that and followed the instructions to "relink" the metadata.plist files in each group, to the GUID to the groups in workgroup manager. First issue, they weren't different GUID strings.
Well, that didn't work...kept getting file not found error. When trying to access the domain.com/groups/groupname...it should've asked for authentication. And let me into that wiki...but no, apache error page.
So, they had me create a new "test" group....added a user. Start and stopped the web...etc. This didn't create a new wiki entry (when we replaced my custom index.html to the default index where groups/wikis/blogs populate automatically at the main). And, there's no new "test" folder in the library/collaboration files.
They then said "well, it must be because you don't have reverse DNS configured right, that's why the new wikis won't set up". I've contacted dyndns.com...but I don't think that's the problem.
So, I've rebooted my xserver to the internal drive. The wiki and blog is still there, still accessible the way I like....I still can't login to the xserver.
So, I'm wondering, if anyone knows a way I can boot up my xserve in the target drive mode, hook up my laptop and replace / swap whatever admin files so that when I boot up my xserve, I can login again.
There has to be a way to hard fix a hidden file? Replace a DB? Some awesome terminal command to get me in and fix the admin account / password....
Or, does anyone know if the reverse DNS issue applecare cites is legit? Doesn't make sense how, the same public ip and domain name, that's worked for some time...suddenly doesn't???
I'm hoping someone can help me.

Accessing Xserve with Lion Server from Windows 7 PC via VNC Viewer

Hello everyone-
At work we have an Xserve running Lion Server that we are trying to access from a Windows PC runnig Windows 7. We have turned on Screen Sharing on the Xserve and we are using RealVNC's VNC Viewer client to access the Xserve.
Everything works OK except the Control key is not being passed through to the Xserve, so you can't to teh usual copy/paste commands etc.
I have checked on the Web but found nothing to resolve this problem. The settings in the RealVNC client are set to pass through special keys, but it is as if the VNC server on the Xserve isn't seeing them.
Does anyone have any ideas?

How to reinstall mac os x server on mac mini 2011

Hi
i need to help
Can i Reinstall "Mac osx lion server "on my MACMINI 2011

Then you will need to boot to the Recovery HD partition included on the internal drive when Mt Lion was installed. To do that at startup hold down the Command+r keys and that will boot the computer from the recovery HD. Once that starts use Disk Utility to Erase the Macintosh HD partition. Once that finishes exit DU and select Reinstall Mac OS X and Mt Lion will be downloaded from the internet and whenn that finishes downloading the install will start. Have the Apple ID and password you used to originally install Mt Lion. And it is best to Wire the computer to your internet router, Ethernet cable from computer to router. You can use WiFi but if for some reason the WiFi drops out you will have to start over from the beginning with the Mt Lion download.

Major version upgrade of WebLogic with zero/minimal downtime

From what I can tell, the recommended approach for supporting minimal downtime during major version upgrades (e.g. WL 9 -> WL 10) is to have 2 domains available in the production environment.
Leave one running to support existing users, upgrade the other domain, then swap to perform the upgrade on the first domain.
We are planning on starting out with WL 9.1, but moving forward we require very high availability...(99.99%).
Is this my only option?
According to BEA marketing literature, service pack upgrades can be applied with "zero" downtime...but if this isn't reality, I'd like to hear more...
Thanks...
Chuck

Have gotten as far as upgrading all of the software, deleting /var/db/.AppleSetupDone, and rebooting. It brought me back in to Setup Assistant and let me choose "migrate from another mac os x server" and is now sitting waiting for me to take the old server down and boot it into target disk mode. Which we can probably do Sunday at about 2am or so...
You know, Setup Assistant should really let you run Software Update BEFORE migrating from another machine. We have servers that can't be down for SoftwareUpdates in the middle of the day...

Migrating Hyper-V 2008 R2 HA Clustered to Hyper-V 2012R HA Clustered with minimal downtime to new hardware and storage

Folks:
Alright, let's hear it.
I am tasked with migrating an existing Hyper-V HA Clustered environment from v2008R2 to new server hardware and storage running v2012R2.
Web research is not panning out, it seems that we are looking at a lot of downtime, I am a VMware guy and I would do likely a V2V migration at this point with minimal downtime.
What are my options in the Hyper-V world? Help a brother out.

Merging does require some extra disk space, but not much.
In most cases the data in the differencing disk is change, and not additional files.
The absolute worst case is that the amount of disk space necessary would be the total of the root plus the snapshot.
Quite honestly, I have seen merges succeed with folks being down to 10 GB free.
But, low disk free space will cause the merge to take longer. So you always want to free up storage space to speed up the process.
Merge is designed to not lose data. And that is really what takes the time in the background. To ensure that a partial merge will still allow a machine to run, and a full merge has everything.
Folks have problems when their free space hits that critical level of 10GB, and if they have some type of disk failure during the process.
It is always best to let the merge process happen and do its work. You can't push it, and you cannot stop it once it starts (you can only cause it to pause). That said, you can break it by trying to second guess or manipulate it.

Schema changes, minimal downtime

We are a software development company, using Oracle 10g (10.2.0.2.0). We need to implement schema changes to our application, in a high traffic environment, with minimal downtime. The schema changes will probably mean that we have to migrate data from the old schema to new or modified tables.
Does anyone have any experience with this, or a pointer to a 'best practices' document?

It really depends on what "minimal" entails and how much you're willing to invest in terms of development time, testing, hardware, and complexity in order to meet that downtime requirement.
At the high end, you could create a second database either as a clone of the current system that you would then run your migration scripts against or as an empty database using the new schema layout, then use Streams, Change Data Capture, or one of Oracle's ETL tools like Warehouse Builder (which is using those technologies under the covers) to migrate changes from the current production system to the new system. Once the new system is basically running in sync with the old system (or within a couple of seconds), you can shut down the old system and switch over to the new system. If the application front end can move seamlessly to the new system, and you can script everything else, you can probably get downtime to the 5-10 second range, less if both versions of the application can run simultaneously (i.e. a farm of middle-tier application servers that can be upgraded 1 by 1 to use the new system).
Of course, at this high end, you're talking about highly non-trivial investments of time/ money/ testing and a significant increase in complexity. If your definition of 'minimal' gets broader, the solutions get a lot easier to manage.

How to reinstall OS X Lion Server

I'm newbie os x admin . I bought new Mac Mini 2010 with Lion Server. I want to do RAID 0 with my HDD.
I make image for Recovery Partition. Then format partition and do RAID 0.
I setup with Mac OS X Lion 10.7 GM build 11A511
I success to install but .... No Lion Server.
I try to check Mac Store but I found I need to buy Lion Server License ?
These is my Question
1. Lion Server that pre-install with Mac Mini is not license version or not?
2. Should I restore from recovery partition and get Lion Server from them ?
3. How I make recovery DVD or anything that easy to reinstall ?
Thank You very much.

The 2010 Mac mini Server did not come with Lion Server, it was shipped with Snow Leopard Server. To go from Snow Leopard to Lion is a paid upgrade, not a free update. Up until Snow Leopard there was a SL client OS and a SL Server OS. Now Lion Server is an add-on purchase to the Lion client. So you must buy and install the Lion client, then the second step is to buy and install the Lion Server add-on. You purchase both Lion and Lion Server through the Mac App Store.

Problem with Mac OS X Lion reinstall - Cannot install on server volume

Hi
I have a MacbookPro 2011 that has been upgraded to Lion from Snow Leopard. I can log on and use the computer but I want to reinstall Lion and make a clean start. I have created a rcovery partition on an external drive and booted to this partition using the option command when re-booting. The Lion install process goes well until the screen which asks you to select the disk where you want to install Mac OS X Lion. The Macintosh HD drive is there, but I cannot select it as I get the following message with it:
You cannot install Mac OS X on a server volume. You need to use disk utility to erase this volume before you can continue to install Mac OS X.
I have no idea why the install is seeing my hard drive as a server volume. I just want to install OS X Lion, preferably using the archive and install option, on a standard MacbookPro. If I go ahead and erase the HD will I still be able to install Lion? How will Apple know that I have already paid for the Lion upgrade if the main HD is erased? I have already created a clone of the existing HD so I have a backup of all files I need.

Slight Update. I found a guy with my EXACT problem here. https://discussions.apple.com/thread/4103108?start=0&tstart=0 Go to this discussion for further details.
