Death of OVM manager. How to recover?

I found myself in a situation where my OVM-manager server got hosed and I had to rebuild it (disks died, and since it's a test environment, no backup of the host exists).
Unfortunately I had previously set up an OVM pool and repository.
I re-mounted a repository NFS share that was in use on the now dead OVM-manager installation. That worked, and it inserted itself into the Storage->Fileservers list
I attempted to reload this share as a repository on my new OVM-manager installation, it told me I couldn't because it belonged elsewhere.
Now that I try to delete it from the list of File Servers, it tells me I can't because
"OVMRU_002005E repo01 - Cannot delete NAS or fileSystem with a repository on it."
This was despite the fact that it is not even recognised a repository on my new OVM manager box.
So I went a deleted the share on the NFS device, but the error persists.
Attempted to rediscover the share, and since it can no longer find it, that doesn't help the new OVM manager decide that is an "ex-NFS mount"
Attempted to re-try deleting the file server mount, but it refuses to go away and out of the list, even though it is not even recognised as a repository on my new OVM manager install.
Seems like OVM has some big issues regarding handling ownership.
On a separate issue, I tried taking ownership of some OVM boxes tied to the old and dead OVM-manager, and I was rebuffed there too.
I went and reinstalled the OVM servers as well.
it seems like the death of an OVM-management server means the death of the entire architecture, including the repository and all files, and forces a complete rebuild.
Any idea how to fix this?

I'm no expert, but I know that the OVM Manager install has an option to force a specific UUID, so the manager will look "exactly like" the original one, and everything works again. I'm not sure that this scenario is applicable to you, since I'm fairly new to all this. But perhaps you can determine what the old UUID was (you may have written it down, or it's stored in your cluster data somewhere, and re-install with that UUID. I think this is mentioned in the docs, and there are postings here about it.

How to start virtual OVM Manager and restore server pool which hosts it?

It had to happen... the day I migrate our OVM Manager from an ESX host into an Oracle VM, we have a massive NetApp outage, and everything fails to come back. As a result of having lock errors when trying to start any VMs I noted on the forum various solutions and ended up following the steps concerning stopping ovs-agent and removal of /etc/ovs-agent/db/* on all the servers. Next I re-added the repo to all the servers using repos.py, but of course now none of the servers are in a pool so the --list command shows them as [R] rather than [*], and the /OVS directory is not yet mapped. So the next stage, according to the instructions which I am following, describes using the 'Restore' option in the OVM Manager GUI. Given that /OVS is not mounted and all of the servers are now config-less, I can't see how I can start the OVM Manager VM to get to the aforementioned "restore" option...
Thank Jeebus I kept the ESX copy of OVM manager on (but powered down), as I was able to fire it up and do the restore, and now everything is hunky dory. However, this is our Dev platform and I was going to build the Prod platform and deploy OVM Manager straight into the OVM architecture via the template, rather than having it on ESX, but this issue on the Dev install has made me think twice about the mobius nature of managing the VM architecture from within the VM architecture...
I am assuming I am missing some sort of commandline knowledge, so... given:
- empty db directory
- root repos [R] on all servers
- as yet unmapped /OVS
...how to get the server pool up and get something back into /OVS, and then start my OVM Manager VM so I can 'restore'? Is it even possible? because if it isn't, I'll be blowed if the Prod OVM manager is going to get deployed like this...
And no, there's no money in the budget for extra tin just to sit there running the OVM Manager and nothing else.
TIA

Still nobody seems to know of how to create a server pool on the CLI (outside of OVM Manager) though...There is no way to create a server pool on the CLI without Oracle VM Manager. You either need to use the Web UI of the Manager, or use the ovmcli command-line tool. Both of those require Oracle VM Manager to be running.
However, once the Pool is created, you do not need the Manager to be running to perform simple tasks like starting/stopping guests. That can be done with the xm command-line tool.
I agree with you about running VM Manager as a guest of the Oracle VM Server: I actually don't recommend this in production, unless you have at least two Server Pools. Then you can have the Manager of Pool A hosted by Pool B and vice-versa. Most often however, I recommend a completely independent Manager machine, either physical or hosted on a separate virtualization stack.

How to create EBS 12.1.1 cloning using OVM Manager

Hi
We are currently running Oracle Application release 12.1.1 and Oracle Database 10.2.0.4.1 on IBM Power 5 on AIX 6.1.
We are in process of Migration the whole environment to Intel based platform our go LIVE date is 26th september 2013 and the vendor has configured the Oracle VM environment, they suggested us to use Oracle VM templates but we did the test migration using iso files of Linux(x86_64) and Oracle DB Home and Oracle Application Techstack
Source (2 server HACMP CLuster) Server1 DB and CONC, server 2 APPS
Oracle Database 10.2.0.4.1
Oracle Application 12.1.1
AIX 6.1
Target (2 Servers OVM Cluster) Guest VM DB, Guest VM APPS
Oracle Database 11.2.0.3.6
Oracle Application 12.1.1
Oracle Enterprise linux 6.4
Oracle VM Hypervisor 3.2.3
Oracle VM Manager 3.2.3
We have completed the migration by installation the OS, DB Home, APPS TECH stack using media because we were unable to get the latest templates from Oracle E-delivery, we need to create a clone of the current setup using OVM Manager and also cloning of EBS Database and APPS tier using the same method without running the cfgclone scripts, help needed.
Thank you

How far is your OVM Manager from your OVM Servers? Any limit?

Does anyone manage OVM servers in a different region from their OVM Manager? I have a 4,000 mile latency between a datacenter in the Country my OVM Servers are going to reside and my OVM Manager which is my home country. Any body doing something like this?
My site-to-site latency is 130-140ms round trip, private network.

In my use case I already have a central OVMM and want to manage the OVM Servers in that region as a pool.

How many time to install/configure OVM Manager and OVM Server ?

Hello,
I wish to have your experience feedback on the mean time needed to install both OVM Server and OVM Manager in a production environement, with e.g : 2 CPUs, 4 G of RAM, or for 4 CPUs and 8 G of RAM.
Regards,
Lionel

Not enough information. XE is not supported in a production environment so you will need to install a SE or EE version of Oracle Database. I would personally use EE because the Virtual Manager comes with a single use license that covers running the VM Manager on either edition. No extra cost to run EE over SE.
You can use kicstart to rapidly deploy any VM Server. If you get your scripting right... it takes less than 10 minutes.

How to recover a TM backup from a NAS drive

I am using a MBPro from 2011. I lost a lot of family pictures due to my iPhoto library loosing the connection to the original hi-res files. At the moment I try to recover those with Data Rescue4 but it looks I lost quite a lot.
Now, I do have the following situation:
Until March 2014 my iPhoto Library resided on my Mac HDD
The HDD broke and had to be exchanged
So I moved the iPhoto Library onto a newly bought 2TB external HDD that I connect via USB (a WD MyPassport Ultra)
Now due to the situation described above, I need to recover the last iPhoto Library that resided on my Mac, but which was never used in iPhoto since the hardware crash
When I open iPhoto and then TimeMachine, it does not offer me to recover pictures from that last backup, which is from March 2014 and is about 135GB large. I assume the reason is that I haven´t used it in iPhoto, so iPhoto can´t know.
The TM backup on my NAS, a 4TB Seagate Central is 1,2 TB large. The seagate central cannot be connected to a Mac via USB or wire. According to it´s description, the only way to get data on and off is via ethernet. Having read that TM does not support backing up from a NAS, I assume I need to copy the 1,2 TB backup TM file onto another external HDD that I can attach via USB. Is this correct ? Does this help ?
And then I would need to recover it - but how given the situation above ??
I am pretty desperate meanwhile as I´ve been working on this for the last four weekends...
Within the process of data recovery I bought iPhoto Library Manager, PhotoSweeper and DataRescue4 in order to help recover the data. But I don´t know if this helps here. I´ve tried everything to recover my old files with those tools already.
I would very much appreciate your advice on how to recover my TM backup.

You can or should be able to recover the iphoto library directly from the NAS.. you do not need to copy it to a disk.
TM cannot create a backup from a network source.. but it is very happy using a network target.
Our friend Pondini wrote extensive notes on recovery of various important files using TM
See Q15 here. http://pondini.org/TM/FAQ.html
There is a link in there to recovery of iphoto in particular under various OS.. but the guy died before Yosemite was inflicted on the Apple Community.
TM has never worked particularly well since Yosemite.. so I can only offer my hope that the method still works..
Here is an example of recovery manually of iphoto library from TM backup I did to show how it is done.
Can't access old files on time capsule
In Yosemite you might be able to simply right click on the file in Finder.. and it bring up an option to recover it from TM.. of course that would assume TM was going to actually work and that is a bridge too far for Yosemite.
In the end.. you can of course do a full recovery to a USB drive plugged into your computer.. I have also used that method to get around issues with finding stuff from old backup.. however IMHO the manual method of digging through the backup offers you the best chance of recovery.
Do protect the TM sparsebundle.. in the end that is the only connection back to you files you have.. so saving a copy of the sparsebundle to a USB drive is not a bad idea.. Certainly do nothing in terms of manipulating the sparsebundle.. you can extract files from it.. copy it to another location.. but make no changes to original sparsebundle on the network drive whatsoever.. so do not continue backups to it or anything like that.
My strong recommendation btw since Yosemite or even Mavericks was to use Carbon Copy Cloner.. and make a bootable backup of your main operating system and any other drives.. You would not be in this mess if you had .. so for future reference.. TM is not really adequate.

How to recover a missing program

Hi guys
Im facing an issue on our SLM system where one of the Z programs is missing. I've checked on SE38 and the program is not listed. I have tried to check on Version Management but there are no previous versions.
The only activity was a EHP 1 Upgrade, but there are no indications where this program was modified or deleted.
I've checked the table TADIR and is present. Also checked table TSTC for the transaction name ZPWC and is also in there.
Since i dont have the original transport since its was brought from an external system, I'd like to check with you guys any idea on how to recover this program. I dont have any clue on how is missing since its not a developement system.
Any recommendation on how to restore/find this program, would be highly appreciated.
Martin
PS: Also Checked in table VRSD if there is an entry with OBJTYPE = u2018REPSu2019 and OBJNAME = name of the deleted program and no luck.

I think you will have to go back to the original development system. The versions will be there.

How to recover backup user data after a restore

I had a disk fail and could not boot. while in the restore software I was able to backup user data to a USB drive. Now that I've restored from the restore partition and got it running windows 7 home again, I don;t see how to recover the user data made with the low level software. Windows back up doesn't seem to recognise it and I can't find an HP utility to get at it.
A program saved with the .wim back up files brought up an HP restore manager application that then copied the filed to my new C drive but how do I actually get it to recover them into their appropriate places and recreate users etc.
Or, should I just consider myself lucky to still have copies of the files at all? I'll not be real happy about that because it will be a tom of work to recreate everything manually even with the files.
I'm hoping someone out there has a better solution for recovering all my user data into my new restored initial image.
thanks,
-dcb

Hello dcbrower, You may be able to use the program Universal Extractor to extract the files in the .wim file.
This is a Free program that can be found at this Link. .
Just extract the files in the wim file to a location you would like.

How to recover data in iPhoto?

How to recover data from iphoto?

I haven't done any conscious backup.
Time to start. Now. Using a computer without a back up is like driving without a seat belt. You'll be fine as long as nothing goes wrong, but if something does go wrong it'll be a much bigger mess.
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Oracle EM and OVM management--where to start?

We are interested in evaluating EM for OVM control, but after a quick glance through the docs it's by no means clear how to start. We have not used EM before this and it's a daunting prospect.
What I'm interested to know is:
1. What is the minimum amount of parts I need to download and install to get OVM management under EM working for a simple environment?
2. Does it really require a full oracle DB installation or will it work with XE?
3. What plugins and agents etc. are/are not required?
It looks simple enough on paper but the EM framework has an enormous amount of apparatus most of which it seems we don't need.
Any pointers greatly appreciated!
Charles Meo

First this is such task where you will learn more but sorry to say it will also take Time. This is not one/two days task.
Yes how to start
==========
I will suggest first dont go with user guides/Implementation Guide, for newbie they are little bit hard as my understanding.
Read small Blogs/Articles and have fast understanding and then go with user guides/Implementation Guide .
These are some article are there web that can hep you

Connection problem to the OVM Manager 3.0.3 Console

My OVM Manager 3.0.3 installation was smooth on top of Oracle Linux 6.0, not even with a single error after taking care of some prerequisite warning stuff at the beginning.
After the installation, it displayed some info on how to connect to the OVM Manager Console.
http://ovmmanager:7001/ovm/console
https://ovmmanager:7002/ovm/console
But, not only neither address seems to work but also the server opens neither port.
I have no problem remotely logging into the shell via ssh.
Trying "telnet ovmmanager 7001" and "telnet ovmmanager 7002" isn't connecting.
Also, Oracle is up and running.
# ps -ef |grep XE |wc -l
31
# ps -ef |grep pmon
oracle 1610 1 0 02:28 ? 00:00:02 xe_pmon_XE
I rebooted it couple of times but the same thing.
Could someone please let me know where I should start?
Thanks.

Hi,
The reason is the /etc/rc.d/init.d/ovmm shell script. It tries to start the weblogic with oracle user. The oracle user doesnt have permission and it fails with a timeout
if [ $action = run ]; then
logger "Starting the Oracle VM Manager application."
echo -n "Starting Oracle VM Manager"
nohup su - oracle -c "$USER_MEM_ARGS DOMAIN_PRODUCTION_MODE=true JAVA_OPTIONS=\"-Djava.awt.headless=true -Xdebug -Xrunjdwp:transport=dt_socket,address=127.0.0.1:8453,server=y,suspend=n -da:org.apache.myfaces.trinidad\" /u01/app/oracle/ovm-manager-3/machine1/base_adf_domain/startWebLogic.sh &" > /dev/null
RETVAL="$?"
fi
change it to
if [ $action = run ]; then
logger "Starting the Oracle VM Manager application."
echo -n "Starting Oracle VM Manager"
nohup su - -c "$USER_MEM_ARGS DOMAIN_PRODUCTION_MODE=true JAVA_OPTIONS=\"-Djava.awt.headless=true -Xdebug -Xrunjdwp:transport=dt_socket,address=127.0.0.1:8453,server=y,suspend=n -da:org.apache.myfaces.trinidad\" /u01/app/oracle/ovm-manager-3/machine1/base_adf_domain/startWebLogic.sh &" > /dev/null
RETVAL="$?"
fi
Thanks,
