Cluster and Backup server

Hello guys;
I want to use a cluster oracle server and another server in another place as a backup server to copy the database on line from the cluster server.
If I want to make the backup server a primary server if something wrong happened to the cluster server.
what the steps should I do? or if there is any document to read I'll be thankful
thanks in advance

Hi,
What do you refer by saying cluster ? If you want to have a HA (High Availability) with Active/Passive cluster then you can go with 3rd party cluster vendor, like HACMP from IBM, ServiceGuard from HP and so on. If you want to create this with Oracle technologies then you are talking about Oracle RAC One Node. Of course you always go with Oracle RAC (Real Application Cluster) if you want to have a Active/Active cluster. These are in terms of cluster and High Availability.
There is another point if you want to create a DR (Disaster Recovery) of you primary database then you would consider implementing Oracle Dataguard.
Oracle has a rich documentation for blueprints and best practices, my sincerely advice is to get familiar with it:

Starting weblogic cluster and admin server on Win 2000 platform

Hi! Here's my problem scenario:
I'm running my WLS 8.1 application as WLS cluster on Win 2000 platform. I have
3 replicated WLS servers in my cluster and of course one WLS server as admin server
(4 WLS servers all together). I'm starting my WLS application using Win services
which behind a scene call win 2000 comand interpreter batch-file to start the
servers. Currently I have 4 different win 2000 services each calling different
batch-files to start a WLS server (4 all together). Here's my question:
Is there any way to start my cluster (3 managed WLS servers) and WLS admin server
from single win 2000 command file (using single win 2000 service). Using win 2000
AT-command interpreter command I can start executables and command(s) and command-files
at background at specific date and time, but I want to start my WLS application
on every win 2000 platform boot, is there any way to achieve this ???
Best Regards!

hi,
Thanks for stepping up!
But I wasn't using any clustering or loadbalancing.
Just a simple Admin server, Managed server set up.
256 Meg, Pentium box running Win 2000 premium edition.
I tried tweeking around the heap size too.... coz' the operations were slogging
like anything...

hi,
I am looking at a strange behaviour with WLS6.0SP1 installed on WINDOWS2000 Premium.
I brought up the Admin server and a Managed server. After a while theAdmin Server
is compeletely
losing the control of the managed server (for no reason).
when I tried monitoring the managed server from the console, I couldnot
access
the manager server
and the status down (red ball). I tried restarting the Admin Server
in the discover mode - NO LUCK.
But when I restart the Managed server and go to the Web Based Admin
Console and refresh, it worked. But I dont think we should be doingthat
in a
production environment.
Did anybody come across such a problem before ???
Is this a problem with Win 2000 ???
coz' it never happened with NT workstation
thanks in advance

          That's not true. Starting a cluster has nothing to do with admin server.
          Infact we always recommend to exclude admin server from cluster view.

Unable to install the backup server using srvbuildres

I am unable to install the backup server with resource file
it gives weiored message which i didnot come across till now.
Open Server Error: 16400.10.0: srv__e3_create_encrypt3_context: Unexpected failure in comn_keypair_create.

this is all in the backuplog and it fails saying unable to boot the server and task failed and backup server not started.
i see that the password encryption is not on i got that by running sp_helpserver <backupsever name>
the staus i got when i ran sp_helpserver is "timeouts, no net password encryption, writable , enable login redirection"
Please help me installing my backupserver.
many thanks in advance.

Please confirm that you're getting this error message while trying to CREATE the backupserver.
The reason I ask is because you mention seeing these messages in the backupserver errorlog, but you wouldn't be getting any messages in the backupserver errorlog unless you were able to successfully install a backupserver.
Also, what is your dataserver/backupserver version strings? (dataserver -v , backupserver -v)
A quick google search turns up Note 1963584:Open Server Error 16400 in ASE Backup Server log when dumping a database. [References SAP note 1963584.]
- same errors as you're seeing, but errors generated while attempting to perform a dump command (ie, backupserver has been installed and is up and running)
- appears to be an issue when "net password encryption" is enabled/true for SYB_BACKUP; if you have net password encryption enabled ... what happens if you disable it?

Does DPM 2012 R2 still needs DataSourceGroups.xml and MaxAllowedParallelBackups key when using Hyper-V VSS Software Writer to backup Server 2012 R2 Cluster

Hi,
Does DPM 2012 R2 still needs DataSourceGroups.xml and MaxAllowedParallelBackups key when using Hyper-V VSS Software Writer to backup Server 2012 R2 Hyper-V Cluster with CSV's? Can't find a clear answer somewhere.
Thanx for helping me out.
DJITS.

Configure CSV backups
If you are running Hyper-V on Windows Server 2008 R2 and you’re backing up multiple clusters with DPM, you need to ensure that only one backup uses the same CSV at any one time. To do this, follow the instructions in
Serialize virtual machine backups.
If you’re using software VSS with Hyper-V on Windows Server 2008 R2, do the following
Serialize virtual machine backups per node
Serialize virtual machine backups per CSV LUN
Have a nice day !!!

Howto take SQL Server 2005 Cluster AND Cluster Group Offline

I need to update firmware on the backend storage used by our Active/Passive SQL Server 2005 Cluster. The first step in the process states that all I/O to the disks should be stopped. Per that, I need to take the the SQL Server cluster offline AND the cluster group; however, I then need to use one of the servers that participates in the cluster to perform the upgrade on the storage array. Using the process (which doesn't account for having to use one of clustered servers to perform updates) outlined at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1550288&SiteID=1 as a basis, below is my best guess regarding what I will need to do:
Shutdown:
1. Backup all of your databases prior to the outage and ensure they are in a safe place (NOT on the disk drives in the cluster)
2. Take the SQL Server group OFFLINE. This will cleanly shutdown the SQL Server and it will remain offline when you power the machine back on.
3. Once SQL Server is offline, power off the node which does NOT have the cluster resource currently running on it
4. Save the node which is running the cluster group for last - make a note of this machine as it will be the first one you power back on. MY ADDITION: Before powering it down, set the cluster service to manual so that when you restart the server to perform the storage array maintenance, the cluster will not be running - and likewise not generating I/O against the disk array.
MY ADDITION: 5. Restart the server from step 4. Takes the cluster offline "cleanly" and brings the server back on line so that the storage array maintenance can be performed.
6. Update the firmware on the storage array. After that is complete, set the cluster service back to "Automatic".
Start up:
1. Restart the server. Per the previous steps, the server to be restarted will be the server that last hosted the cluster group and the one used to update the firmware on the storage array.
2. RDP into the node, open cluster administrator, and verify that the cluster came back online successfully and everything looks clean
3. Power on the second node.
4. Failover the cluster group across each node in the cluster and validate that everything looks OK
5. Bring your SQL Server groups back online
6. Validate that everything is operational
Is there a better way to do this or official documentation for the process?
Thanks.

FYI: I did use the process outlined above to briing the cluster offline, perform updates, and bring it back online. It worked as I had hoped. As a test, I had also done the same on a test [non-SQL] cluster prior to making the updates to our SQL cluster. Is it the best way to do it? Who knows. Did it work? Yes.

Break cluster and move databases to new server

Hello everyone. I have a question that may be basic but I am by no means a SQL person. Right now we have a SQL 2005 cluster running on VM ESXi with a celerra backend storage. Some drives are mapped Raw. We recently put in a new
VNX and we are not able to migrate the SQL server over due to how the drives are mapped. I am thinking that I want to build a new SQL server and move the databases. The new build will not be a cluster since we have point in time recovery manager
from EMC. Now my thinking is, can I break the cluster, move the 2nd node to the new ESXi and storage and present new storage or would it be best to just build a new server? Is it easy enough to change an instance name after SQL is running?
Several applications refer to the SQL Cluster and they are critical so I need something with least amount of downtime. Would doing backup of all of SQL and then a restore to the new system be best? Any thoughts or direction? Thanks
Joe M

The most straightforward and reliable method is to build a new server, migrate the databases using backup/restore, test the new server, and cut-over by shutting down the old servers and either reconfiguring the client applications or renaming the new server
to have the same network name as the old server's SQL Cluster Client Access point.
You can also use DNS redirection instead of renaming the new server, although using a DNS hostname alias for your server requires some additional security configuration. EG

Recently backing up my ipad onto my macbook, which is the backup server for all of my gadgets. This includes all my photos and tons of music. The macbook said it could not backup the ipad because there was insufficient disc space to do so. What now?

I have a macbook operating OSX10.6.7. Recently backing up my ipad which had lots of photos from a recent vacation. I use this laptop as the backup server for all of my gadgets so it has thousands of photos and tons of music. It just told me that it couldn't back up the ipad bc there wasn't enough disc space. I was afraid that this would happen eventually. What next? Newer laptop with more space? I'm not sure what files I could sacrifice to free up more space as most of these are important.

What size hard drive do you have in your MacBook? The cheapest options are, a larger internal hard drive, or an external drive. Or you could get a cheap desktop PC and network to it for storage. I've got one that lives in the hall with 3 Terabytes (That's 3000gb) of storage.

Address Book and iCal Server backups

I'm working to implement a company-wide Address Book, iCal, and iChat server via Lion Server where I work, and I've gotten most of the setup figured out (I think), and am approaching the point where I can roll it out to a few users for further testing. However, before I'm allowed to move forward any further w/ it I have to have two means of backing up in place and ready to be rolled out at the same time as the server—so I'm planning on using Time Machine as one so it does the entirety of the server and its data/settings, but they also want me to do one of the Address Book Server and iCal Server databases individually, like back up the folder the data is, so we can, if ever necessary, import the backup databases to another computer, so we at least have the content, if not the full server functionality. And, for obvious reasons, it can't be backed up locally.
So I'm looking for a means of doing this and would love any input anyone has. Ease of use/setup is pretty important as this is my first time setting Server up and I've no programming knowledge. I'm fairly sure I'll be able to find (or write my own, though that's unlikely) or modify and AppleScript that simply copies/duplicates a Finder item, and I know I can have iCal automatically run a script (so I'd just have it run every night at midnight or something), but I have yet to figure out how to get the script to copy the folder to a specified location on a different server (or, for that matter, if it's even possible, though I'm sure it is...right?). But that's not what I'm trying to ask here...though I certainly wouldn't mind if someone had thoughts on it and wanted to share them ! I just really would like to know which folders to back up, since it's not simply making an archive of the local Address Book.app database.
And, since I'm already here writing a post, I'll ask one other question that's been nagging at me: in Server Admin.app, with the server (not the services) selected in the sidebar on the left, the Access pane selected in the primary Server Admin window, and Services selected, and trying to dictate which users/groups can access which services, the user can click the "+" in the lower-left corner of the window where added users would appear, and another window pops up next to the Server Admin window that shows a list of the users (and groups if you click the appropriate button). My question is, why does it show me _krb_anonymous, _krb_changepw, and a total of 81 other items? I understand more or less what they are (in a very general sense), but why are they shown as users? More importantly, do they have to be listed there? Technically I'm probably the only one that's going to be the administrator, and I'll know not to add them or modify them, but I don't want anything related to those items appearing in a directory search in Address Book when I get it set up (as they are showing up now; for instance, one user I created is Sandy, and I have it set to include directory contacts in searches, so on a client machine that is correctly communicating w/ the server (add a user, it appears in a minute on another client machine, and vice versa) if I go to search for that name as soon as I type "s" Sandy, the actual user shows up, but so do five or six other things, all of which are items from the aforementioned list in Server Admin (pretty much anything that has an "s" in it, which of course makes sense)—and that's what I don't want, I don't want the users to search for someone, see something like _krb_anonymous pop up, then think something is screwed up and call me and demand I come fix their computer!).
Any thoughts, suggestions, and such are more than welcome and much appreciated!
Thank you to all...

Various network setups for media serving and backups

Are there any good sites, blog posts, etc that show different home network configurations with a Time Capsule, external HDs and Macs for handling backups and media serving? Right now I have a simple Setup where my TC backs up my MBP. I also have a couple externals HDs w a lot of music and video that's not in my iTunes library on the MBP, the HD of which is at capacity. I know I want to be able to easily access all of that content on my MBP, AppleTV, iPhone, iPad. I also want to have a good backup solution (possibly even a backup of the backup for redundancy). I just don't know the simplest way to do it and haven't found a good resource to see the alternatives and/or pros/cons of different configurations. Any suggestions would be greatly appreciated!

Can I use Azure Backup and Windows Server Backup in a Windows Server ?

Can I use Azure Backup and Windows Server Backup in a Windows Server ?
I want to use both Azure Backup and Windows Server Backup for two senarios.
For Disaster Recovery = Azure Backup to Azure Storage.
For non-Disacter Recovery = Windows Server Backup to a on-premises disk.
The non-Disaster Recovery mean a file or folder recovery, disk crash recovery, migrate to another servers.
The non-Disaster Recovery need the speed of recovery just like 10 TB recovery as soon as possible.
If I can use both Azure Backup and Windows Server Backup in a Windows Server,
Are there any notes for using both ?

Yoshihiro Kawabata

Hi Yoshihiro Kawabata,
Thanks for posting here!
Azure Backup to Azure Storage and Windows Server Backup to a on-premises disk. These are two different question and can be answered individually.
Azure Backup to Azure Storage - Possible.
Windows Server Backup to a on-premises disk - Possible.
Can I use Azure Backup and Windows Server Backup in a Windows Server? Is a question.
I will check on this and get back to you at the earliest.

Turning Media Server on makes Lenovo EZ Media and Backup Center un-usable

I have a Lenovo EZ MEdia and BAckup Center. It was sent to me (under warranty) to replace an Iomega model which failed.
If I turn on Media Server the device becomes un-usable. Logging onto the device and then selecting any operation takes 5 to 10 Minutes for each interaction. All windows network drives configured to the device become inaccessible.
When I turn it off then I can access all my windows networked drives again and I can log on and interact with the device without problem. Obviously anything which needs the media server function can no longer see the device.
I have the latest firmware 4.1.106.31982
This problem really needs fixing. I will be looking for another device if this carries on

Hello wafitz
I seems you are experiencing a variation of this issue "Media scan causes the device interface to become unavailable".
I have also seen similar situations that happened when data is added to the unit when media server is enabled.
This could cause media server to potentially lock and cause performance issues to the rest of the unit.

Set up a media server and backup

I hope I picked the best community for maximum exposure to this set of questions:
I want to build a video distribution system. I have teh ability to send audio throughout the house and HD video via 2 CAT 6 in every room. From my research and being an Apple fan this is what I am thinking about doing. I am considering not using the CAT 6 for video and using wired or wireless connections at one of several locations to get video and other media.
Here is what I have: Airport Express (extender mode), Aiport Extreme, Netgear Gigabit switch feeding the wired locations. I have some older WD MyBooks connected via the network and a USB 500GB drive connected to the Airport Extreme for Time Machine backups - of just my MBP, not my wife's MBP.
1. Should I buy a Mac Mini to act as the media server for the house? I suspect I could have 4-5 locations at once demanding media via Apple TV or xBox 360 (via connect 360). I would like to not buy more than 1 Mac mini. I have considered stuff by Request Media and they are really expensive compared to the cost of one or even two mac minis.
2. I want to have all of the media stored on a RAID 1 network attached drive (or Firewire, Thunderbolt, USB 3.0 whatever). I also want to be able to backup the computers in the house to this storage too. Possible? Lacie seems to have a good product, but, pricey.
3. I suppose I could put a large hard drive in the Mac Mini and store all the media there and use the RAID 1 system to back up all computers somehow. It seems Time Machine freaks out when more than one computer backs up to the same drive.   Is there a better way than Time Machine?
In essence I want to put together a system that supports media distribution via multiple streams via wired or wireless network connections to 3-4 locations simultaneously, backup everything, and store everything video and audio and I am looking for recommendations.
Thanks many!

As previously stated, iTunes libraries cannot be accessed
simultaneously by to different computers. This would pretty
much rule out having an Apple TV and other Mac(s) using
the same iTunes library at the same time. Unfortunately,
Apple TV needs iTunes for any local network streaming.
However, ther are other ATV type devices out there that can
access files directly on any network storage.
There are also other media apps (PLEX, XBMC,etc.) that
can simply be set up to link to network storage systems.
Personally, I am using XBMC on my Macs and all are
linked to media files that are located on HDD attached to
my Airport Extreme Base Station.
2. I want to have all of the media stored on a RAID 1 network attached drive (or Firewire, Thunderbolt, USB 3.0 whatever). I also want to be able to backup the computers in the house to this storage too. Possible? Lacie seems to have a good product, but, pricey.
There are various options here. Something to consider, is
LaCie's Thunderbolt to SATA adapter:
http://www.lacie.com/us/products/product.htm?id=10574.
You could then get one of OWC's RAID enclosures w/ SATA
interface and roll your own storage. Advantages of this approach
1. The RAIDs will be hardware RAID.
2. You could have two independed RAID systems attached
      for various reasons or puposes.
3. Higher speed disk interface vs. USB3.
4. You can also install highest speed HDD's available if
      desired.
5. If a a single disk drive goes belly-up, replacement is fast
      and easy.
6. Also, upgrading to larger drives is a matter of just swapping
     the HDD itself.
3. I suppose I could put a large hard drive in the Mac Mini and store all the media there and use the RAID 1 system to back up all computers somehow. It seems Time Machine freaks out when more than one computer backs up to the same drive.   Is there a better way than Time Machine?
With this sort of system, I would avoid putting data inside
and libraries inside the Mini. Should the HDD fail, your whole system
and data will be down. I would suggest get a Mini with a single
SSD drive with OSX and install Server on it. Being solid state,
it will in the long run be more reliable than a mechanical HDD.
Then put all data and libraries on external storage. If any of
the data/library drives fail, repair/replacement will be quick
and simple.
For your purpose, you don't need to by the "Server" model.
Just get either the base or next one up and just install the
server app on it.

and rserver DAS1 goes down what will be behaviour of sticky and balancing?
New connection wel'll go towards DAS2 or a tricky and clever sticky take precedence? (i mean persistence on DAS1_1 that is my backup server..)
tnx

Hi Danilo,
If your primary rserver goes down the sticky entries associated with that server will be automatically flushed from the sticky table so that
all new incoming connections will be diverted to your backup rserver.
In case that primary rserver comes back then:
- Existing connections on backup keep accessing backup.
- For new connection requests ACE looks up sticky entries, if there's already an entry for backup server the connections is sent to the standby rserver.
- If a new client request (connection) doesn't match any sticky entry for backup rserver ACE forwards this request to primary.
In case that you want to use the primary rserver for all the connections after coming back to operational state then the backup option would be configured like this:
rserver Primary
ip address 10.10.10.2
inservice
rserver Standby
ip address 10.10.10.3
inservice
serverfarm host Primary
rserver Primary
    inservice
serverfarm host Standby
rserver Standby
    inservice
