Using xgrid - shared file system possible?

I have a question about running a sequence of unix commands with xgrid.
I just started fiddling with xgrid and I am already able to run a sequence of renderings in parallel. This is cool and relatively easy.
The software I use for rendering is called Radiance and it is able to share a cache file between renderings of the same scene.
This cache speeds up rendering time sensibly.
Cache is optional and at the moment I am not using this option.
I can render a sequence but I am not using this option as each calculation is performed by a different agent in a self contained folder while the cache file is meant to be a shared file.
It would be great to be able to reference to a single cache file with all the agents... perhaps on a shared volume...
But how can I set this up?
Is it possible to have agents sharing a single working directory?
Any idea?
Anybody using unix commands with a similar option/requirement?
Thanks for your help in advance
G.

But how can I set this up?
At its simplest level, just setup a file server on one machine and have all the other machines mount that sharepoint.
Is it possible to have agents sharing a single working directory?
The agent doesn't care, it's up to the application you're running across the grid and whether it's designed to deal with shared directories and the fact that other processes may be reading/writing the same files. Therefore in order to answer this you need to look more closely at the tasks you're running. Since you say it supports it, you should be OK.

Shared file system between Int and ext server(DMZ) in R12.1.3 for iRec

Dear Friends,
we are using R12.1.3 and we planned to use iRec module.
so we decided to go with External web tier and it will be placed in DMZ for external users.
Is it possible to have shared file system between internal and external web server when external server is in DMZ?
Is it safe to go with shared application Tier file system between internal and external server (or) to have seperate file system in externel web tier?
Regards,
DB

Take a look at Note 380490.1 DMZ Deployment for R12.
Also For Specific Load balancer 727171.1 Up to 12.x but alot of the information is still usefull based on hardware loadbalancer
Also Note 1309013.1 has some good information on SSO/OAM Intergration with E-Business Suite

Shared file system and other questions

Hi,
 Is shared file system common for all WL in the cluster or each WL has its
 own one.
 Next questin is connected with proxy server.
 I'm not sure if there should be one proxy server for two servers working in
 one cluster or each server should has own proxy server (I mean WL proxy
 server).???
 In my opinion there should be one proxy server which redirect requests to
 server in cluster using some balancing method. But when I read documentation
 about cluster's architectures I saw the picture where each WL cluster server
 had proxy own server. I'm not sure if this picture showed only outline of
 architecture or it was real solution???
 Is it better to install another proxy server (for example Apache) than WL
 proxy server?
 In previous questions I asked if it is possible to replic static classes,
 fields etc. Prasad Peddada told that it is not replicated. But I wonder if
 there exists some method to force replicating it.? Maybe we can implement
 some method and run it?
 Thanks,
 Best regards,
 Robert


Mike.
 In WLS51 cluster, it is better to specify different workingDir for each
 server. You can create a weblogic.properties in your per-server directory
 and add jspc properties in that file.

WebLogic as Windows 2000 service over s shared file system

I am trying to install weblogic as a Windows 2000 service over a
shared file system with no sucess
(the shared fie system is provided by windows 2000 cluster services).
I am using the srvany utility to have the script that launches
weblogic be run as a service (I need this
because I must launch 2 instances of weblogic in the same machine
as services, i cannot do this
with the bea service tools, having different configurations for
the classpath, or can I?)
The service works if weblogic is not installed in a shared file
system.
On the shared file system, it fails (The service fails, is unabble
to start). I also made a script on the local file
system, that calls the weblogic script on the shared file system,
but weblogic fails to start (with no
message) when loading from the weblogic.classpath
thanks for your attenction,
Bruno Antunes
WhatEverSoft - Java Center

I have also tried running the service with the bea tools, with no
sucess when running in
the shared file system.
When i start the service, it seems to start ok, then stops. with
no message.
Nothing is written to the log, any ideas?

Regarding shared file system requirement in endeca server cluster

Hi,
Our solution involves running a single data domain in an endeca server cluster.
As per the documentation, endeca server cluster requires shared file system for keeping index file for follower node to read.
My questions are,
Can I run the endeca cluster with out shared file system by having the index file on each node of the endeca server cluster?
Can dependency on shared file system be a single point of failure, if yes how can it be avoided?
I really appreciate your feedback on these questions.
thanks,
rp

Hi rp,
The requirement for a shared file system in the Endeca Server cluster is a must. As this diagram shows, the shared file system maintans the index, and also maintains the state of the Cluster Coordinator, which ensures cluster services (automatic leader election, propagation of the latest index version to all nodes in the data domain). A dependency on a shared file system can be a single point of failure and requires to run a backup, -- this is a standard IT approach, that is, it is not specific to the Endeca Server cluster in particular.
See this section on Cluster Behavior, for info on how the shared file system is used (the topic "how updates are processed"), and on how increased availability is achieved.
HTH,
Julia

Shared file system recomended for OCR and voting Disk in 10g R2

Hi,
If your using standard edition then you got no choice but raw devices

Oracle RAC binaries on vxfs shared file system

Hi,
Is it possible to install oracle binaries on vxfs cluster file system for oracle RAC under sun cluster? Because as I know we can not use vxfs cluster file system for our oracle datafiles.
TIA

The above post is incorrect. You can have a cluster (global) file system using VxVM and VxFS. You do not need to have VxVM/CVM for this. A cluster file system using VxVM+VxFS can be used for Oracle binaries but cannot be used for Oracle RAC data files where they are updated from both nodes simultaneously.
If further clarification is needed, please post.

RAID/ shared file system for clustering

could somebody give me the h/w config,vendor etc.. used generally to
provide failover to the shared file system for cluster of weblogic
servers?

Many of our customers use either a hardware or software raid to protect
their filesystem for the cluster. Most of this is a vendor specific --
you should check out the documentation for your specific platform.
Another option is to not do a single filesystem for the cluster. They
should be free self-explanatory -- you simply need to replicate all of
the files, application code, etc. across the cluster in each individual
server machine.

Know use% of a file system

Can anyone of you please tell me the way of filtering the information obtained when a 'df -k' command is given. I am actually trying to get only the 'use%' of a file system.

Why not lear the format of a df command first?
You can do so by reading a manual page on it.
Call the manual page with this command: man df.
My favourite for percentages is this:
df -h
Reports usage in human readable form.
You filter output by grep command, like this:
df -h | grep TheDiskIwantToSee_Or_AnyOtherString
Now give me two "Duke Dollars" (see on the left of your screen).
I am tired of answering easy questions, which easily can be found in documentation, or have been already previously asked.

How adutilities comes to know that the file system is shared file system

How adutilities comes to know that the file system is shared file system ?
In multinode shared file system : if we want genearte message file we can invoke adadmin from any node and perform this activity. In this case, how adadmin knows that the filesystem is shared filesystem.

Maintain snapshot on shared file system

Hi,
We have Shared file system. Want to know whether I need to run Maintain Snapshot on all application nodes? or running on one application node is enough?
Apps Version: 11.5.10.2
DB: 10.2.0.4
Regards,
Raju

Hi Raj,
As AD Administration "Maintain snapshot information" for an APPL_TOP completely populates the APPL_TOP's current view snapshot. Here you have shared APPL_TOP, So there is only one set of files.
So i believe you need to run only once.
Thanks

Help! what is the default location for shared file system?

Help! i came in this morning and for some bizarre reason the shard file system information had disappeared and podcast producer wouldn't work i thought it was in library/quicktimestreaming/movies so i set it to there but when i try and submit a video i just get question-marks in the post where the video should be its obviously not finding it. So i found where most of the previous videos were which is a folder called Podcast Producer which seems to be a link to my external drive but when i set the shared file system to this folder it creates a new folder called podcasts and sticks them in there so i get the same question-mark scenario. Its bizarre i can't figure out why it would losse the information in server admin the only thing i can think of is that i did a repair permissions and wondered if it might have set some permission on the shared filesystem folder differently and made it somehow inaccessible does anybody know what permissions should be set on the folder? Also regarding quicktime streaming does this location have to be the same as the shared file system folder?

Thanks - The folder was hidden, so once I changed my options to see hidden files, I was able to find it exactly where the link told me it would be.
Much appreciated!

Is it possible to install OL6.2 with UEK using btrfs root file system?

Can we use btrfs for root file system with Oracle Linux?
If yes - how to install it? (OL6.2 installer doesn't offer btrfs within the available file systems).

For what it's worth, I tried the following, which worked:
host: vm022
cd /etc/yum.repos.d
rm public-yum*
wget http://public-yum.oracle.com/public-yum-ol6.repo
+Edit public-yum-ol6.repo and enable [ol6_UEK_latest]+
yum update kernel-uek
yum install btrfs-progs
The system was successfully updated to UEK2 - 2.6.39-100
Boot the system form Fedora 15 Live CD and open a terminal. Enter the following:
su - root
yum install btrfs-progs
lvscan
btrfs-convert /dev/vg_vm022/lv_root
(conversion complete)
mount /dev/vg_vm022/lv_root /mnt
Edit /mnt/etc/fstab and change the root volume filesystem from ext4 to btrfs
umount /mnt
reboot
Start from the OL6.2 DVD in rescue mode. Select continue to let if find the existing Linux system and drop into the shell
chroot /mnt/sysimage
modprobe btrfs
lsmod | grep btrfs
cd /boot
cp initramfs-2.6.39-100.5.1.el6uek.x86_64.img /root
mkinitrd -f -v /boot/initramfs-2.6.39-100.5.1.el6uek.x86_64.img 2.6.39-100.5.1.el6uek.x86_64
exit
unmount /mnt/sysimage
After another restart (it restarted twice doing some volume/label converison - didn't catch it)
mount
/dev/mapper/vg_vm022-lv_root on / type btrfs (rw)

Partitioning previously used Windows NT File System for use with Mac and PC

With reference to this thread I found when searching for a solution: Can Windows NT File System(NTFS) format external hard drive work on iMac?
Below is the comment which led to me creating this new thread.

Hi there,
I am about to follow your advice also for the same issue, the worry I have is that when I select partition 1, it says "To erase and partition the selected disk..." and so I am worried that if I do this it will erase the current contents of the hard disk drive (which were copied there from PCs in previous use).
If so, is there a way to use the hard disk drive with a mac without erasing the contents?
Thanks
Your case is different and NO do not partition the EHD yet unless you are prepared to completely erase your PC data. Before progressing though, do you intend to share the EHD with a PC and your Mac? If so this is not advisable but it is possible, however you will need to compromise. Please answer that question first and then we can proceed with some advice.
BTW it's generally not a good idea to ask a question in a thread that has already been answered, particularly one that is 3+ years old! In such a case it's normally better to create your own thread. "
The answer to the question in the above comment is that ideally I would like to use with both Mac and PC, why is this not advisable?
Please discuss my best options. I am wondering if I could transfer the current contents of the disk drive elsewhere, partition (which would erase) the disk drive, then put back the contents along with the new files which I have been trying to put on in the first place?
If this were to work would I then be tied down to only using this disk drive with a Mac?
Thank you.

Ideally it is best to have seperate (discreet) EHD's for a PC and Mac due to their differences in HD formatting. However, this is not always feasable but there are alternative solutions availble. Among those are:
Creating and useing a Dropbox account that can be shared by PCs, Macs, IOS and Android devices. Dropbox allows for 2GB of free storage and additional storage is available for a small monthly fee.
Another possiblity is formating an EHD so that it may be shared by both a PC and Mac, this format is FAT 32. The downside of doing this is the size of the files written to the HD are limited to 4GB.

How do I use a NAS file system attached to my router to store iTunes purchases?

We have four Windows devices networked in our house. They all run iTunes with the same Apple ID so when any one of them has iTunes running, we can see that computer on our Apple TV. Two run Windows XP, one runs Vista Business, and the newest runs Windows 7. Upgrading all to the same Windows software is out of the question. Our NAS is hung on an "off warranty" Linksys E3000 router which communicates via USB with a 1TB NTFS formatted Western Digital hard drive. Our plan when we set up this little network, not cheaply, in our 1939 baloon construction tank of a house, was to build our library of digital images, music, and video primarily on that device. It supports a variant of Windows streaming support, but poorly. The best streaming support for our environment seems to be our ethernet connected Apple TV which is hung off the big TV in our family room, and has access to the surround sound "Home Theater" in that room. We've incrementally built up collections of photos, digitized music, and most recently educational materialsd, podcasts, etc. which threaten storage limits on a couple of default C: drives on these windows systems. iTunes, before the latest upgrades, gave us some feedback on the file system connections it established without going to the properties of the individual files, but the latest one has yet to be figured out. MP3's and photos behave fairly well, including the recently available connection between Adobe software and iTunes which magically appeared, allowing JPEG files indexed by Adobe Photoshop Elements running on the two fastest computers to show up under control on the Apple TV attached 56' Samsung screen!
Problems arose when we started trying to set things up so that purchases downloaded from the iTunes store ended up directly on the NAS, and when things downloaded to a specific iTunes library on one of the Windows boxes caused storage "issues" on that box. A bigger problem looming in the immediate future is the "housecleaning" effort which is part of my set of "new years resolutions." How do I get control of all of my collections and merge them on the NAS without duplicate files, or when, for example, we have .ACC and .MP3 versions, only the required "best" option for the specific piece of music becomes a candidate for streaming?
I envission this consolidation effort as a "once in a lifetime" effort. I'm 70, my wife is 68 and not as "technical" as I am, so documented procedures will be required.
I plan to keep this thread updated with progress and questions as this project proceeds. Links to "how to" experiences which are well documented, etc. may be appreciated by those who follow it. I plan to post progress reports and detailed issues going forward. Please help?

Step 1 - by trial and error...
So far, I have been able to create physical files containing MP3 and JPG on the NAS using the Windows XP systems to copy from shared locations on the Vista and Win7 boxes. This process has been aided by the use of a 600 GB SATA 2 capable hard drive enclosure. I first attach to Win 7 or Win Vista and reboot to see the local drive spaces formatted on the portable device. Then I copy files from the user's private directories to the public drive space. When the portable drive is wired to an XP box, I can use Windows to move the files from the portable device to the NAS without any of the more advanced file attributes being copied to the NAS. Once the files are on the NAS, I can add the new folder(s) to iTunes on any of the computers and voila, the data becomes sharable via iTunes. So far, this works for anything that I have completely purchased, or for MP3's I made from the AIC files created when I purchased alblums via iTunes.
I have three huge boxes full of vynl records I've accumulated. The ones that I've successfully digitized via a turntable attached to the sound card on one of my computers and third party software, have found their way to the NAS after being imported into iTunes and using it to bring down available album art work. In general I've been reasonably well pleased with the sound quality of digital MP3 files created this way, but the software I've been using sometimes has serious problems automatically separating individual songs from the album tracks and re-converting "one at a time" isn't very efficient.
