Shared disk for weblogic cluster

Hi Gurus,
I've googled about the subject, but didn't find any specific.
Could somebody explain,
Is it possible/certified to create weblogic domain on a clustered file system (i.e. OCFS2)?
I would like to build a cluster with common domain home.
Regards,
Mikhail

Hi Saurabh,
What is the best way to have some shared data
within a cluster. This data needs to be in memory
only, no need for DB persistence. But it can be
upadted (in memory only) and updates should be
visible to any of the servers with in the cluster.
For example - I want to create a hashtable to be
shared within cluster and the hashtable can be
modified from time to time.Tangosol Coherence does just that:

It even supports the same Hashtable API!

ACFS recomandations for weblogic cluster

Hi,
Can some one help me to findout material(step by step) for ACFS usage with weblogic clustering.
Originally I started thread here :
Re: ACFS recomandations for weblogic cluster
Thanks in advance for valuable time
Datla

The first question you need to ask yourself is for what purpose do i need this type of filesystem when using a WebLogic Cluster?
The first which comes to mind is the migration of so-called singleton service, such as JMS Servers, persistence stores and JTA.
For example, when a machine fails, we must bring the services, running on the failed machine, up on other machines. The JTA
service plays a critical role in recovery from a failure scenario where transactions are involved. In-flight transactions can hold locks
on underlying resources. If the transaction manager is not available to recover these transactions, resources may hold on to these
locks for a long time. This makes it difficult for an application to function properly. JTA service migration is possible only if the server's
default persistent store (where the JTA logs are kept) is accessible to the server to which the service will migrate.
This where a shared storage mechanism comes into play - to store files which need to be accessible from every server. The concept
of ACFS which is useful in this scenario is the mount model (http://download.oracle.com/docs/cd/E14072_01/server.112/e10500/asmfilesystem.htm#CACJGEAC)
To set-up a mount point you can follow the steps presented here: http://download.oracle.com/docs/cd/E15051_01/wls/docs103/cluster/service_migration.html#wp1049463

Shared Disks For RAC

Hi,
I plan to use shared disks to create Oracle RAC using ASM. What options do I have? OCFS2? or any other option?
Can some one lead me to a documnet on how can I use the shared disks for RAC?
Thanks.

1. Create shared virtual, i.e. file-backed disks. These files will be stored in /OVS/sharedDisk/ and made available to each guest
2. Expose physical devices directly to each guest, e.g. an LVM partition or a multipath LUN.
With both options, the disks show up as devices in the guests and you would then provision them with ASM, exactly the same way as if your RAC nodes were physical.
OCFS2 or NFS are required to create shared storage for Oracle VM Servers. This is to ensure the /OVS mount point is shared between multiple Oracle VM Servers.

WFC without Shared Disks for SCVMM Failover

SCVMM Failover Cluster requires us to first have a WFC in place. If shared disk is the limitation, can a WFC be created without shared disks? just to fulfill the purpose of providing WFC to the SCVMM Failover Cluster.

Thanks for the reply. Actually, design is not my decision unfortunately.
I have gone ahead with a disk witness and I have used Shared VHDX as a Quorum Disk. I faced some issues when I live migrated, but when I enabled Guest Services on both nodes which is disabled by default, it started migrating fine.
Please, do share your thoughts on it. Especially with respect to Shared VHDX and Live migration and the overall strategy as MS always prefers Disk Witness to File Share Witness.

Shared disks for clusterware

Hi:
I am setting up Oracle Clusterware. I am trying to set it up on two nodes. This i on AIX and trying the latest version 11gR2. I am selecting the first option ( Install and Configure Grid Infrastructure for a Cluster)
I am trying to setup shared disk by mounting a file system of one system on the other using NFS.
Here are my questions.
I am creating user "oracle" on both the boxes. I am adding all the groups (like dba, oinstall etc.)
Here are my questions:
The NFS mount I have which is accessible by both the boxes should be used only for OCR (Oracle Cluster Registry) and Voting Disk (CF). I do not have ASM.
Is it correct?
Also
The Oracle Base(eg : /u01/app/grid ) and Software Location(eg : /u01/app/11.2.0/grid) can be local to each individual nodes
Is it correct?
Those are the two questions I have. Also, will this work?
I have tried to put everything on the shared disk (installation files, OCR, CF, base, inventory etc) but looks like the second box (the one from where I have not installed) is having problem. Because it is trying to change ownership of user and group of a few files when I run orainstRoot.sh and root.sh.
Please let me know
Thanks

Hi,
The NFS mount I have which is accessible by both the boxes should be used only for OCR (Oracle Cluster Registry) and Voting Disk (CF). I do not have ASM.
Is it correct?Use documentation of Oracle GI 11.2
http://docs.oracle.com/cd/E11882_01/install.112/e24614/storage.htm#CDEJIDFB
Why not use ASM? Since is more safe and have more performance.
Also
The Oracle Base(eg : /u01/app/grid ) and Software Location(eg : /u01/app/11.2.0/grid) can be local to each individual nodes
Is it correct?
Those are the two questions I have. Also, will this work?For grid infrastructure for a cluster installations, the Grid home must not be placed under one of the Oracle base directories, or under Oracle home directories of Oracle Database installation owners, or in the home directory of an installation owner. During installation, ownership of the path to the Grid home is changed to root. This change causes permission errors for other installations.
http://docs.oracle.com/cd/E11882_01/install.112/e24614/preaix.htm#BABFCFIH
Please follow the installation guide, all your question here is easily answered on documentation:

Doubts about shared disk for RAC

Hi All,
I am really new to RAC.Even after reading various documents,I still have many doubts regarding shared storage and file systems needed for RAC.
1.Clusterware has to be installed on a shared file system like OCFS2.Which type of hard drive is required to install OCFS2 so that it can be accessed from all nodes??
It has to be an external hard drive???Or we can use any simple hard disk for shared storage??
If we use external hard drive then does it need to be connected to a seperate server alltogether or can it be connected to any one of the nodes in the cluster???
Apart from this shared drives,approximately what size of hard disk is required for all nodes(for just a testing environment).
Sincerely appreciate a reply!!
Thanks in advance.

Clusterware has to be installed on shared storage. RAC also requires shared storage for the database.
Shared storage can be managed via many methods.
1. Some sites using Linux or UNIX-based OSes choose to use RAW disk devices. This method is not frequently used due to the unpleasant management overhead and long-term manageability for RAW devices.
2. Many sites use cluster filesystems. On Linux and Windows, Oracle offers OCFS2 as one (free) cluster filesystem. Other vendors also offer add-on products for some OSes that provide supported cluster filesystems (like GFS, GPFS, VxFS, and others). Supported cluster filesystems may be used for Clusterware files (OCR and voting disks) as well as database files. Check Metalink for a list of supported cluster filesystems.
3. ASM can be used to manage shared storage used for database files. Unfortunately, due to architecture decisions made by Oracle, ASM cannot currently be used for Clusterware files (OCR and voting disks). It is relatively common to see ASM used for DB files and either RAW or a cluster filesystem used for Clusterware files. In other words, ASM and cluster filesystems and RAW are not mutually exclusive.
As for hardware--I have not seen any hardware capable of easily connecting multiple servers to internal storage. So, shared storage is always (in my experience) housed externally. You can find some articles on OTN and other sites (search Google for them) that use firewire drives or a third computer running openfiler to provide the shared storage in test environments. In production environments, SAN devices are commonly employed to provide concurrent access to storage from multiple servers.
Hope this helps!

Problem configuring front end host for weblogic cluster

hi,
I am using weblogic 8 sp4,I have a cluster of WLI servers for which i am trying to configure a front end host.I am using apache Http server 2.0.55 for the same.
I copied the mod_wl_20.so file to the modules directory and added the following to httpd.conf file
LoadModule weblogic_module modules/mod_wl_20.so
<IfModule mod_weblogic.c>
WebLogic http://myIP:9191,http://myIP:9192,http://myIP:9193
ErrorPage http://myerrorpage1.mydomain.com/
MatchExpression *.jsp
MatchExpression *.xyz
</IfModule>
<Location /weblogic>
SetHandler weblogic-handler
PathTrim /weblogic
</Location>
however,the error page gets displayed and not the default weblogic page.
When I change the Error page url to that of my cluster url(i.e)http://myIP:9191, the weblogic default page gets displayed .. I mean to say that the same url doesnot work with the WeblogicCluster parameter but works with
the ErrorPage parameter.
Somebody who has configured the front end host using apache http server please clarify, it would be of great help.
Thanks in advance

The error.log displays the following (sorry i forgot to add it above :-()

Setting up a shared disk for Time Machine

Folks,
I have a 24" Al iMac with an external 750GB disk allocated to time machine.
This machine has a single account with administrative privileges "me".
I have a second 20" snow iMac that I would like to backup to the same disk.
It has 4 accounts, one of which has administrative privileges (also called "me").
How do I need to configure sharing on the Al iMac to allow time machine on the snow iMac to see the drive on the Al iMac, and be able to backup/restore to this volume?
I have searched the forums here but cannot seem to find this information.
Thanks in advance.
- ljm

Turn on Filesharing in the "Sharing" preference pane on both computers (You might want to specify which users have access via filesharing). Then on the snow imac connect to your Aluminum imac and mount the external drive so you can access it. Go to the TM settings and select the Aluminum imac's drive that's now shared and mounted, and start the initial backup. It will create a "sparsebundle" disk image on the backup drive and use that for the snow imac's backup. Everytime it writes to the image, it will mount it over the network and do a backup, and then eject it. Sometimes it wont back up to the image if you're not connected to the Aluminum mac, so to solve this, select the mounted shared drive as a "login item" in the snow imac's user preferences (for each user). This will create the connection on login, and backups should proceed accordingly.

How to make iTunes watch a shared disk for new music?

I have a small home network with a shred disk with all the music we purchased ripped neatly into it.
I wish my iTunes software to watch this disk and let me play music from there and creates playlists in order to update my iPOD.
I do not wish to manually import every time as existing songs are imported over and over and if I clear the library and re import the playlists are erased.
Please suggest a solution.
Thanks

Shalom, Ofer.
iTunes doesn't offer any sort of folder watching feature.
about If the folder is added once more - I get duplicates.
That shouldn't happen.
Unless your files on the server are WMAs, or you have messed up settings.

Extreme + Shared Disk through a NAT?

Hi,
I've done a search on this topic but can't find a thread that answers my question - so I beg forgiveness if this has been asked and answered many times...
I've got an Extreme base station hosting a shared disk for a small business LAN. It works great.
This past weekend I put in a D-Link router into one of the offices to help reduce traffic noise (I've got an Ethernet-based interface for outboard automation and it was previously very laggy). The router does exactly what I need it to - except I can't use the Airport Disks menu to mount the Airport Disk.
The Disk shows up in the menu but returns a "Connection Failed" dialog box. I can connect to the Disk directly through Finder > Go > Connect to Server
I'm thinking some ports need to be opened up.
Anyone know where I can find that info?
Or perhaps something else is going on?
Thanks.

Yup. Punch through the D-Link to the AEBS.

Use storage as shared disk

We have storage connected to one server using optic port.Can i make shared disk for future install Oracle Clusterware(for 2 node).thanx

I probably wouldn't use iSCSI in this manner for a production database unless I had no other choice. My biggest issue is that one more piece is added to the configuration that can fail that can affect availability. If that other host goes down, so does the shared storage that is mounted to the database server. I might do this as a short-term solution to get me immediate access to disk, but I would then immediately procure additional disk storage and get that into the configuration as soon as it arrives.
Cheers,
Brian

Mapping shared disk mount in Linux

Hyper-V cluster Backup causes virtual machine reboots for common Cluster Shared Volumes members.

I am having a problem where my VMs are rebooting while other VMs that share the same CSV are being backed up. I have provided all the information that I have gather to this point below. If I have missed anything, please let me know.
My HyperV Cluster configuration:
5 Node Cluster running 2008R2 Core DataCenter w/SP1. All updates as released by WSUS that will install on a Core installation
Each Node has 8 NICs configured as follows:
NIC1 - Management/Campus access (26.x VLAN)
NIC2 - iSCSI dedicated (22.x VLAN)
NIC3 - Live Migration (28.x VLAN)
NIC4 - Heartbeat (20.x VLAN)
NIC5 - VSwitch (26.x VLAN)
NIC6 - VSwitch (18.x VLAN)
NIC7 - VSwitch (27.x VLAN)
NIC8 - VSwitch (22.x VLAN)
Following hotfixes additional installed by MS guidance (either while build or when troubleshooting stability issue in Jan 2013)
KB2531907 - Was installed during original building of cluster
KB2705759 - Installed during troubleshooting in early Jan2013
KB2684681 - Installed during troubleshooting in early Jan2013
KB2685891 - Installed during troubleshooting in early Jan2013
KB2639032 - Installed during troubleshooting in early Jan2013
Original cluster build was two hosts with quorum drive. Initial two hosts were HST1 and HST5
Next host added was HST3, then HST6 and finally HST2.
NOTE: HST4 hardware was used in different project and HST6 will eventually become HST4
Validation of cluster comes with warning for following things:
Updates inconsistent across hosts
  I have tried to manually install "missing" updates and they were not applicable
  Most likely cause is different build times for each machine in cluster
   HST1 and HST5 are both the same level because they were built at same time
   HST3 was not rebuilt from scratch due to time constraints and it actually goes back to Pre-SP1 and has a larger list of updates that others are lacking and hence the inconsistency
   HST6 was built from scratch but has more updates missing than 1 or 5 (10 missing instead of 7)
   HST2 was most recently built and it has the most missing updates (15)
Storage - List Potential Cluster Disks
  It says there are Persistent Reservations on all 14 of my CSV volumes and thinks they are from another cluster.
  They are removed from the validation set for this reason. These iSCSI volumes/disks were all created new for
  this cluster and have never been a part of any other cluster.
When I run the Cluster Validation wizard, I get a slew of Event ID 5120 from FailoverClustering. Wording of error:
  Cluster Shared Volume 'Volume12' ('Cluster Disk 13') is no longer available on this node because of
  'STATUS_MEDIA_WRITE_PROTECTED(c00000a2)'. All I/O will temporarily be queued until a path to the
  volume is reestablished.
Under Storage and Cluster Shared VOlumes in Failover Cluster Manager, all disks show online and there is no negative effect of the errors.
Cluster Shared Volumes
We have 14 CSVs that are all iSCSI attached to all 5 hosts. They are housed on an HP P4500G2 (LeftHand) SAN.
I have limited the number of VMs to no more than 7 per CSV as per best practices documentation from HP/Lefthand
VMs in each CSV are spread out amonst all 5 hosts (as you would expect)
Backup software we use is BackupChain from BackupChain.com.
Problem we are having:
When backup kicks off for a VM, all VMs on same CSV reboot without warning. This normally happens within seconds of the backup starting
What have to done to troubleshoot this:
We have tried rebalancing our backups
  Originally, I had backup jobs scheduled to kick off on Friday or Saturday evening after 9pm
  2 or 3 hosts would be backing up VMs (Serially; one VM per host at a time) each night.
  I changed my backup scheduled so that of my 90 VMs, only one per CSV is backing up at the same time
   I mapped out my Hosts and CSVs and scheduled my backups to run on week nights where each night, there
   is only one VM backed up per CSV. All VMs can be backed up over 5 nights (there are some VMs that don't
   get backed up). I also staggered the start times for each Host so that only one Host would be starting
   in the same timeframe. There was some overlap for Hosts that had backups that ran longer than 1 hour.
  Testing this new schedule did not fix my problem. It only made it more clear. As each backup timeframe
  started, whichever CSV the first VM to start was on would have all of their VMs reboot and come back up.
I then thought maybe I was overloading the network still so I decided to disable all of the scheduled backup
and run it manually. Kicking off a backup on a single VM, in most cases, will cause the reboot of common
CSV members.
Ok, maybe there is something wrong with my backup software.
  Downloaded a Demo of Veeam and installed it onto my cluster.
  Did a test backup of one VM and I had not problems.
  Did a test backup of a second VM and I had the same problem. All VMs on same CSV rebooted
Ok, it is not my backup software. Apparently it is VSS. I have looked through various websites. The best troubleshooting
site I have found for VSS in one place it on BackupChain.com (http://backupchain.com/hyper-v-backup/Troubleshooting.html)
I have tested almost every process on there list and I will lay out results below:
  1. I have rebooted HST6 and problems still persist
  2. When I run VSSADMIN delete shadows /all, I have no shadows to delete on any of my 5 nodes
   When I run VSSADMIN list writers, I have no error messages on any writers on any node...
  3. When I check the listed registry key, I only have the build in MS VSS writer listed (I am using software VSS)
  4. When I run VSSADMIN Resize ShadowStorge command, there is no shadow storage on any node
  5. I have completed the registration and service cycling on HST6 as laid out here and most of the stuff "errors"
   Only a few of the DLL's actually register.
  6. HyperV Integration Services were reconciled when I worked with MS in early January and I have no indication of
   further issue here.
  7. I did not complete the step to delete the Subscriptions because, again, I have no error messages when I list writers
  8. I removed the Veeam software that I had installed to test (it hadn't added any VSS Writer anyway though)
  9. I can't realistically uninstall my HyperV and test VSS
  10. Already have latest SPs and Updates
  11. This is part of step 5 so I already did this. This seems to be a rehash of various other stratgies
I have used the VSS Troubleshooter that is part of BackupChain (Ctrl-T) and I get the following error:
  ERROR: Selected writer 'Microsoft Hyper-V VSS Writer' is in failed state!
  - Status: 8 (VSS_WS_FAILED_AT_PREPARE_SNAPSHOT)

So, basically, everything I have tried has resulted in no success towards solving this problem.
I would appreciate anything assistance that can be provided.

Tim,
Thanks for the reply. I ran the first two commands and got this:
Name
Role Metric
Cluster Network 1
3  10000
Cluster Network 2 - HeartBeat                              1   1300
Cluster Network 3 - iSCSI                                    0  10100
Cluster Network 4 - LiveMigration                         1   1200
When you look at the properties of each network, this is how I have it configured:
Cluster Network 1 - Allow cluster network communications on this network and Allow clients to connect through this network (26.x subnet)
Cluster Network 2 - Allow cluster network communications on this network. New network added while working with Microsoft support last month. (28.x subnet)
Cluster Network 3 - Do not allow cluster network communications on this network. (22.x subnet)
Cluster Network 4 - Allow cluster network communications on this network. Existing but not configured to be used by VMs for Live Migration until MS corrected. (20.x subnet)
Should I modify my metrics further or are the current values sufficient.
I worked with an MS support rep because my cluster (once I added the 5th host) stopped being able to live migrate VMs and I had VMs host jumping on startup. It was a mess for a couple of days. They had me add the Heartbeat network as part of the solution
to my problem. There doesn't seem to be anywhere to configure a network specifically for CSV so I would assume it would use (based on my metrics above) Cluster Network 4 and then Cluster Network 2 for CSV communications and would fail back to the Cluster Network
1 if both 2 and 4 were down/inaccessible.
As to the iSCSI getting a second NIC, I would love to but management wants separation of our VMs by subnet and role and hence why I need the 4 VSwitch NICs. I would have to look at adding an additional quad port NIC to my servers and I would be having to
use half height cards for 2 of my 5 servers for that to work.
But, on that note, it doesn't appear to actually be a bandwidth issue. I can run a backup for a single VM and get nothing on the network card (It caused the reboots before any real data has even started to pass apparently) and still the problem occurs.
As to Backup Chain, I have been working with the vendor and they are telling my the issue is with VSS. They also say they support CSV as well. If you go to this page (http://backupchain.com/Hyper-V-Backup-Software.html)
they say they support CSVs. Their tech support has been very helpful but unfortunately, nothing has fixed the problem.
What is annoying is that every backup doesn't cause a problem. I have a daily backup of one of our machines that runs fine without initiating any additional reboots. But most every other backup job will trigger the VMs on the common CSV to reboot.
I understood about the updates but I had to "prove" it to the MS tech I was on the phone with and hence I brought it up. I understand on the storage as well. Why give a warning for something that is working though... I think that is just a poor indicator
that it doesn't explain that in the report.
At a loss for what else I can do,
