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

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.

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,

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?

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

Dear Friends,
For Oracle 10g R2 (10.2.0.5) 64 bit which shared file system is recomended for OCR and voting Disk (NFS / raw devices / OCFS2)
For Datafiles and FRA i planned to use ASM
Regards,
DB

Hi,
If your using standard edition then you got no choice but raw devices
http://docs.oracle.com/cd/B19306_01/license.102/b14199/options.htm#CJAHAGJE
for ocfs2 you need to take extra care

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.

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.

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.

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?
Message was edited by: purplemonkey1

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!

SUN VM Shared File Systems make Errors with lucreate

Hi,
I have a problem with an attached A5200 with mirrored disks (Solaris 9, Volume Manager). Whereas the "critical" partitions should be copied to a second system disk, the mirrored partitions should be shared.

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.

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.

RMAN to Disk (shared mounted file system) then secure backup to Tape

Hi
This is a little away from the norm and I am new to Oracle secure Backup.
We have several databases on physically separate servers, all backup to a central disk (a ZFS shared file-system).
We have a media server also with the same mounted file-system so it can see all of the RMAN backups there.
Secure backup is installed on the media server and is configured as such.
The question I have is I need to backup the file system to tape where all the RMAN backups live, I have configured the data set but I get file permission errors for each of the RMAN backup files in the directory.
I have tried to change these permissions but to no avail (assuming it is just a read write access change that is needed - but this may be a problem in the long run). What is the general process for backup of already created RMAN backups sat in a shared area? I know its not the norm to do to disk then to tape backups but can this be done? I would have installed Secure backup client on each server and managed the whole backup through secure backup but this is not possible I must do the to tape from the file system, any advise and guidance on this would be much appreciated.
Kind regards
Vicky
Edited by: user10090654 on Oct 4, 2011 4:50 AM

You can easily accomplish a very streamlined D2D2T strategy! RMAN backup to disk...then backup that disk to tape via RMAN and OSB. Upon restore, RMAN will restore from best media disk or tape based on where files are located.

Shared and non-shared application file system in R12

Hi,
We have a oracle apps 11.5.10.2 on mutli node architecture with node 1 hosting DB,CCM and admin while node 2 hosting Form and web servers on Windows 2003.
Some of our Products are in Shared status(Installation) like AD,AU etc and I found that R12 currently does not support the shared file system infrastructure on application tier server nodes running on Windows platforms
Metalink note:384248.1
what will be the impact of this if we plan for R12 upgrade?
Thanks!
Shekhar

Hi Shekar,

I'm slightly confused by your question. Shared application tier file system isn't supported on Windows platforms in 11i, either. From Note 233428.1: 
<blockquote>
The shared file system infrastructure is not supported on application tier server nodes running Windows platforms or using Oracle9iAS releases earlier than 1.0.2.2.2. Application tier nodes must be running on the same operating system to implement a shared file system.
</blockquote>

Are you perhaps referring to the licensing status of your Applications products (i.e. either Installed, Shared, or Not Installed) from the Installed Products report in OAM? If yes, then this should have no impact on your upgrade to R12...those statuses should remain the same when you upgrade. "Shared" in this case relates only to the licensing status of the product, implying that the product is not explicitly licensed (i.e. Installed status), but its functionality is required for used with other Installed products.

Regards, 
John P.
