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.

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

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?

Oracle Express Edition And Windows Encrypted File System (EFS)

Hello,
I want to use oracle express edition with windows encrypted file system. I tried some possibilities like encrypting xe folder. But connection can not be established when efs is used. Is there a compatibility problem between oracle xe and windows efs? On Oracle's page, it is declared that oracle database is compatible with Windows EFS.
Thank you for help.

Pl identify which version of Win 7 - 32-bit or 64-bit ? Home version or something else ?
The 11g XE install is only available for 32-bit version of Win 7 Professional or higher - http://docs.oracle.com/cd/E17781_01/install.112/e18803/toc.htm#BABHICJH. If you are installing on 64-bit version or Home version of Windows, then you are on your own. What is the reason for enabling EFS on this database ?

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.

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

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?

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!

Uploaded Files stored in Oracle 10G database or in Unix File system

Hey All,
I am trying to understand best practices on storing uploaded files. Should you store within the database itself (this is the current method we are using by leveraging BLOB storage) or use a BFILE locator to use the files system storage (we have our DB's on UNIX) . . .or is there another method I should be entertaining? I have read arguments on both sides of this question. I wanted to see what answers forum readers could provide!! I understand there are quite a few factors but the situation I am in is as follows:
1) Storing text and pdf documents.
2) File sizes range from a few Kb to up to 15MB in size
3) uploaded files can be deleted and updated / replaced quite frequently
Right now we have an Oracle stored procedure that is uploading the files binary data into a BLOB column on our table. We have no real "performance" problems with this method but are entertaining the idea of using the UNIX file system for storage instead of the database.
Thanks for the insight!!
Anthony Roeder

Anthony,
First word you must learn here in this forum is RESPECT.
If you require any further explanation, just say so.
BLOB compared with BFILE
Security:
BFILEs are inherently insecure, as insecure as your operating system (OS).
Features:
BFILEs are not writable from typical database APIs whereas BLOBs are.
One of the most important features is that BLOBs can participate in transactions and are recoverable. Not so for BFILEs.
Performance:
Roughly the same.
Upping the size of your buffer cache can make a BIG improvement in BLOB performance.
BLOBs can be configured to exist in Oracle's cache which should make repeated/multiple reads faster.
Piece wise/non-sequential access of a BLOB is known to be faster than a that of a BFILE.
Manageability:
Only the BFILE locator is stored in an Oracle BACKUP. One needs to do a separate backup to save the OS file that the BFILE locator points to. The BLOB data is backed up along with the rest of the database data.
Storage:
The amount of table space required to store file data in a BLOB will be larger than that of the file itself due to LOB index which is the reason for better BLOB performance for piece wise random access of the BLOB value.

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.

Oracle rac raw device as shared storage

Hi,
i m new to oracle rac,
and i wish to instlall 11g r1 RAC on my laptop having linux 4 as platform (on vmware) ,
for that i prepare 4 partition for that (on node1)
/dev/sdb1 - for ocr
/dev/sdb2 - for voting disk
/dev/sdb3 - for asmdisk group
/dev/sda5 - fro asmdisk group
by assuming external redundacy for ocr and voting disk i kept only one disk
and i configured following in /etc/sysconfig/rawdevices
/dev/raw/raw1 /dev/sdb1 -- ocr
/dev/raw/raw2 /dev/sdb2 -- voting disk
/dev/raw/raw3 /dev/sdb3 -- asmdisk group
/dev/raw/raw4 /dev/sdb5 -- asmdisk group
and my question is how node2 can understat these raw device as shared storage?
thanks for any support

hi thanks for your suggestion ,
this may be ok for VMware , but what about for non-VMWare environment?
how can i make raw device as shared storage?
one more, all the docs that i followed on net , configured node1 partitions as shared storage.
please help me in this regards
