RAC Storage Options (2 nodes)

Dear Friends,
I have 2 machines with windows 2000 operating system. I want to install a 2 node Oracle Cluster 10g R2. I want to use the same nodes to for stroge also. Is it possible? This installation is for testing purpose. I have got just 2 computers. What is stroing database and cluster files on RAW disk?
How can we share disks in 2 nodes sanerio where storage will be performed on the same nodes. Is there any step wise how to ... to install RAC with these options?
Please help in details.
Regards,
Imran

RAC Storage Options ( Openfiler or Wasabi )

Hi RAC gurus..
I need your advice regarding storage options for our RAC development environment.
Since it is a development environment so management is reluctant to invest in SAN , Our production is a 2 node RAC on windows 2003 server mounted on Dell SAN.
We have two spare servers available with Intel Xeon processors and SAS disks on them. SAN is out of question here and since we are on windows we cannot use NAS.
I was reviewing the storage options and came across to Openfiler and Wasabi Storage Builder softwares which can transform your server ( spare ones ) into virtual SANs for shared storage purposes.
I want to know if its reliable, scalable and whether it can be put to production one day or not? Which one is better Openfiler or Wasabi ?

whether it can be put to production one day or not?
you need to ask this to oracle support to get a correct answer ; moreover for a production system, I will only use certified hardware .

RAC storage options

hello
please confirm the following
1- the voting disk should be on shared storage
2- the OCR should be on shared storage
3- the database files ( datafiles..control files) should be on shared storage
4- what about the the clusterware files ( local for each node or shared ?) which one is recommended
5- what about also the the oracle server files ( local for each node or shared ?) which one is recommended
thanks

1- the voting disk should be on shared storage
2- the OCR should be on shared storage
3- the database files ( datafiles..control files) should be on shared storage
TRUE
4- what about the the clusterware files ( local for each node or shared ?) which one is recommended
LOCAL to each node.
5- what about also the the oracle server files ( local for each node or shared ?) which one is recommended
When you say server files, I assume it is the Oracle RDBMS binaries, if yes, you have the option of having them either local to each node or shared. But, it is recommended to have the binaries local to each node (for allowing rolling upgrades of ASM, eliminating your binaries as being a SPOF), I am sure others will have more to add or comment.

Oracle White Paper- Storage Option for RAC. on Linux

hi..
This in reference with White Paper.. Stotage Option for RAC on LINUX. Author- Umadevi Byrappa.
Which states on page 10: To Use NAS for RAC database file storage select the file system storage option in OUI. or the Clustered file system storage option in DBCA.
With which i disagree. File storage option of oracle 10g RAC only shows.
1. Clustered File system.
2. ASM
3. Raw Devices.
When i try to select Cfs and select the shared directory on NFS it says. < Directory_Name> is not a clustered file system or Shared on Both <Server_1> < Server_2>. and at this point of time i m stuck.
1. I dont want to use OCFS as its not supporting NAS.
2. Selecting CFS doesnt recognise mounted shared volume as valid storage device option can only store OCRfile and CSS file.
3. So, I have to use ASM.. with zero padded files..which i dont want to because no other option. ( PART NO. B10766-02 PAGE C-6)
Also, I would like oracle to provide Back up Recovery Option or Document which tells me how could i Recover Database when i use Zero Padded Files.
What would be the best Option in the above scenario ?
I hope by applying patch or with workaround somehow it shows Filesystem ONLY.I'll be the happiest man in this Case.
Any suggestions and corrections are most welcome. I wish i m wrong.

NFS isn't a clustered file system at all - by RFC it is an exported file system with access controls
If your vendor offers an NFS solution over and beyond that - more power to them. However that isn't "NFS"..
http://www.faqs.org/rfcs/rfc3010.html
You can use NFS in a clustered server environment (to mount apps, read only data and for synchronous access to files), however it doesn't support the concurrency out of the box for RDBMS transactions - if a vendor is supporting this promise then that is for you to decide.
However i stand by my statement that NFS is a file system exported across your network and not a full clustered file system.

Best storage option

hello
is GPFS on AIX considered the best storage option for oracle RAC ?
thanks

1) ASM is Oracle best practice for storage of both single instance and RAC 10g Oracle databases
2) Once you use it and know it, there is no come back from ASM, is by far the best performing, easy to manage and flexible storage option.
3) Dont be afraid of raw devices + ASM, you will configure your raw devices once and then all the work you have to do is from time to time just add new disks according to your requirements, ASM + Oracle Managed Files will do all the dirty job: Extend datafiles, balance and spread IO.

There is no mass storage option on my Blackberry / Using USB to export photos to computer.

I am trying to transfer photos from my Blackberry. I do not have a data plan or a micro sd card, so the usb mass storage option is (I believe) the only way for me to get my photos off my phone and onto my computer.
I plug the usb cord into my computer and phone, but my computer does not recognize the phone as a storage device, so when I click on "Removable Disk (E)" in My Computer, I get prompted to insert a disk into the drive.
I read that in order for this to work, I need to enable mass storage on my Blackberry. I go to options, device, and storage; however, there is no "Mass Storage" option even listed there. The only two options with check boxes are "Enable Compression" and "Media Card Support."
Is the mass storage option elsewhere on the Blackberry Curve? I have tried restarting my phone, computer, using different usb ports, and using different usb cords to no avail. How can I get my photos off my phone?
Solved!

Seeking advice on Best Practices for XML Storage Options - XMLTYPE

Sparc64
11.2.0.2
During OOW12 I tried to attend every xml session I could. There was one where a Mr. Drake was explaining something about not using clob
as an attribute to storing the xml and that "it will break your application."
We're moving forward with storing the industry standard invoice in an xmltype column, but Im not concerned that our table definition is not what was advised:
--i've dummied this down to protect company assets
CREATE TABLE "INVOICE_DOC"
   (     "INVOICE_ID" NUMBER NOT NULL ENABLE,
     "DOC" "SYS"."XMLTYPE" NOT NULL ENABLE,
     "VERSION" VARCHAR2(256) NOT NULL ENABLE,
     "STATUS" VARCHAR2(256),
     "STATE" VARCHAR2(256),
     "USER_ID" VARCHAR2(256),
     "APP_ID" VARCHAR2(256),
     "INSERT_TS" TIMESTAMP (6) WITH LOCAL TIME ZONE,
     "UPDATE_TS" TIMESTAMP (6) WITH LOCAL TIME ZONE,

What is a best practice for this type of table? Yes, we intend on registering the schema against an xsd.
Any help/advice would be appreciated.

Hi,
I suggest you read this paper : Oracle XML DB : Choosing the Best XMLType Storage Option for Your Use Case
It is available on the XML DB home page along with other documents you may be interested in.
To sum up, the storage method you need depends on the requirement, i.e. how XML data is accessed.
There was one where a Mr. Drake was explaining something about not using clob as an attribute to storing the xml and that "it will break your application."I think the message Mark Drake wanted to convey is that CLOB storage is now deprecated and shouldn't be used anymore (though still supported for backward compatibility).
The default XMLType storage starting with version 11.2.0.2 is now Binary XML, a posted-parsed binary format that optimizes both storage size and data access (via XQuery), so you should at least use it instead of the BASICFILE CLOB.
Schema-based Binary XML is also available, it adds another layer of "awareness" for Oracle to manage instance documents.
To use this feature, the XML schema must be registered with "options => dbms_xmlschema.REGISTER_BINARYXML".
The other common approach for schema-based XML is Object-Relational storage.
BTW... you may want to post here next time, in the dedicated forum : {forum:id=34}
Mark Drake is one of the regular user, along with Marco Gralike you've probably seen too at OOW.

Photos App compression while using Optimized Mac Storage option

I just purchased a MacBook Pro 512 for personal and work use, 512 GB SSD. My main system at home is a Mac Mini with a Pegasus Raid with 2.9 TB, and I'm keeping all my 55K photos and video library there, which takes about 289 GB of storage. I'm also synchronizing with iCloud, so my entire library is in there. I know I can't sync with my iPhone 6+ 64GB because it will fill up the space and create all kinds of issues (case already open, no resolution yet).
My question is, does anyone know what the compression rate is for storing a local copy of the iCloud Photos library while choosing the Optimize Mac Storage option?
This is very crucial for me for different reasons: When downloading my Photos library to my work laptop, I don't want to fill up my 512 GB drive with photos and not have room for work documents. So it'll be nice to know in advance how much space this library will take. In addition to that, my Internet service provider has a 300 GB a month allowance and this initial download would probably take a big hit over that number, so if I can know how much data is going to be downloaded in advance, I can probably do the download from a location other than my house.
Thanks,
Pablo

RAID is not an option/not available/missing in BIOS Storage Options?? HP Envy 700-047c

Hello - I have an HP Envy 700-047c. It came with a 2 TB HD. I put in another 2 TB HD same model/type. The system in the BIOS and Windows 8 sees the new drive. However, when I boot and go into F10 BIOS/HP Setup utility, go to Storage menu, select Storage Options, my only option is SATA Emulation and the only 2 select options it shows are AHCI and IDE. This is where I should see RAID option - it is not there.
I tried changing SATA ports on the motherboard - no help.
I tried disabling Secure Boot and UEFI and chose Legacy - no help.
I updated to latest BIOS for this PC - no help.
I installed Intel Rapid Storage Technology software and can see the 2 drives within Windows but there is no create option on the Status page like there should be (because you need to enable RAID in the BIOS which the option is missing).
I looked on the motherboard and don't see any jumpers that are labeled RAID (ie. some physical trip).
I called Intel and they confirmed the Intel chipset I have is RAID capable but to contact HP to see if they turned off. I contacted HP and twice they said they are not trained in RAID and do not support it. I contacted the local Microcenter tech support and they found a link on this website talking about how to go to the area I'm in - but the RAID option is not there.
Does anyone know how to get RAID enabled on this HP 700-047c in the BIOS/Setup utility? Help!

UPDATE BY ORIGINAL POSTER TO BELOW - The below is not accurate about RAID being disabled on "All" HP home line computers per research from Big_Dave (Thanks!) - It is what I was told by the HP Escalation Team Friday however - not just my MB but all - which we are seeing is not correct per the customizable Envy model in the following post. It may just be certain models or just my current model's MB...?? I struck thru some of the detail, but leaving it mostly intact so others can see the misinformation I was given.
Thanks for passing along. Below is what I found out about how RAID is disabled by HP now.
I also had an email going back and forth with HP support and they sent to HP Escalation team who I ended up talking with yesterday who researched it for a day and found out that HP has disabled RAID on the motherboard for all of their home PC line! As we were thinking above. Only servers can do RAID now is the word. Hard to believe they'd do that. The rep said he believed it had to do with people calling HP when they lost data due to setting up using RAID 0 and thinking that protected them (all it does is make a big disk, no redundancy like RAID 1).
To me that is no reason to turn off a feature of the Intel chipset. They also don't make this clear to any HP employee as no one I've talked to (3 now along with chat and email) knew that HP is crippling the capabilities of the MB and chipset. I even have a several year old HP Pavilion that has RAID enabled on it under my desk and has saved me twice from disk failure (running RAID 1 mirroring).
I'm pretty disappointed with HP decision to do this and that it's poorly recorded (in fact not recorded at all) it so that I wasted hours upon days trying to figure it out with tech support people. If HP wants to remove a much needed service such as RAID it should be mandatory for them to disclaim that right in the Specfications sheet. RAID IS DISABLED AND CANNOT BE TURNED ON ON ANY HP HOME CONSUMER COMPUTER.
Note: I even called AMI (American Megatrend, Inc.) with HP on the line who said they sold the MB to HP fully capable of RAID which is what led the escalation rep to research to whomever he talked to and found out HP is disabling it out the door to their unaware consumers.
I also asked if HP tech team disabled it, would they be willing to send me a BIOS flash to re-enable it - ie. make that an option for those who are knowledgeable about RAID and can setup. The response was they probably won't. I pressed a little but didn't get anywhere - seems like a reasonable request to me/option to keep people happy.
Luckily I'm within my return window and will be taking this computer back. Sad considering how much time I've put into it thinking I had a computer capable to do what I need.
Anyway - please help spread the word so HP can get this into their knowledge DB and boards that RAID is GONE - removed purposefully by HP.

What's the FASTEST file storage option ?

Hi all,
Im building an application in Java where indexing and storing of data is a major area of the app. It should be able to store the data as well as retrieve them rapidly as well as the files should be small in size.
Knowing Java's popularity with XML, I've chosen that as one candidate, but the problem is Im not too sure how the above 2 criteria will match with XML.
1) Is XML fast enuf considering retrieval of data ?
2) And how about the[b] storage sizes ?
Or should I scrap XML and build my own version file structure such as a B-tree ?
How difficult would that be considering limited development time ?
thanx in advance ....

Anyway to deal with this post piece by piece.
I agree with you that database infact rules out other
options when it comes to speed and storage. Im not in
anyway trying to abuse XML as a storage mechanism. If
I had the freedom to use a database, I know I wudnt
even hav posted this question, cos database wins
hands down in ease of programmin, maintain, store and
rapid response.
Okay first of all my post was not a personal attack against you. There are plenty of people who abuse or ty to abuse XML as a storage mechanism with extremely unhappy results. I want to make that point clear not just to you but to any future readers of this thread so that if they are considering such a course of action they should come back to reality.
It wud be insane to ask the client to
to install a DBMS jus to make sure the P2P app wud
run. As for the details about the solution, it is a
P2P app, but not to share content as such traditional
ones. Its supposed to help ppl arrive at better
seacrh results on a Web Search Engine.Well this was dealt with previously. In short using JDBC does NOT imply a full blown database server. It could be a standalone database like Access or you could write your own driver that accesses a proprietary file directly or you could use a plain text driver.
The point is that if you use JDBC you decouple your application from the storage. This is the important point. Because it means you can switch the storage mechanism as best fits you later without having to rewrite gobs of code.
>
As for the requiremtns, I need a storage mechanism
sm to store the rankings a user might have given
indivuidually per page or website. I need to store
them as well as access them anytime I want and share
them with the peers. Not only rankings I need to
store other deatils like the search string, the
datetime of the query etc.All the more reason to look at a database of some sort... an embedded database would be fine.
>
I will let you know more of the requiremtns as soon
on as I advance onto it. Right now Im not
concentratin on the storage part of it. ( Jus
thinking of goin ahead with XML ) and rather
implementing the P2P communication area. I was jus
doing some research on what would be the best storage
option for dealing with the app's "data". I read
on a book that B-Tress and such data structures can
actually be implemented on file storage thus giving
better performance. And also I was looking for
material ( white papers and such ) discussing the
various issues of each storage option available
currently which will stand as proof for the final
solution I am gonna take.
Okay here is the problem with all this. How do you think databases implement indexes?
Hint: while it is all in the end vednor specific the answer is some sort of tree structure.
So again back to the point if you want to write your own tree structure go right ahead... I think it's pointless but go right ahead. What you should do though is write it so that your application accesses this structure through JDBC so that later when you decide that re-inventing the wheel was not such a hot idea you can change the storage implementation without destroying your application.

Storage option for Non leaf level dimension members: Store vs Dynamic calc

Hi All,
What is the general rule regarding the storage options for non leaf level members? My understanding is that it should be Dynamic Calc under normal circumstances and have it as store if we are going to load data at non leaf level. Is this correct? Are there any other considerations while defining the members?
Thanks and Regards,
Amol

Don't forget to consider whether the dimension is sparse or dense. Upper level dynamic calcs generally work well on dense dimensions as long as you aren't entering data into upper level members. Upper level dynamic calcs in a sparse dimension CAN work well, but usually only on smaller dimensions. This really depends on what else you have going on in your cube. On large sparse dimensions, upper levels are almost always stored, but this is one of those areas where you can sometimes bend the rules.
Also, don't forget to consider the calc order implications of making something stored or dynamic.

the Wifi storage options are interesting but it seems they only allow to read files from the device on the iPad but not transfer files to the storage device via WiFi.
I'm looking for a possibility to use the iPad for photography while traveling, without the access to a computer.
Shooting photo's in RAW format crates pretty big files that will fill up the iPad's memory pretty fast if you shoot a lot during a (let's say) month long trip.
my idea was to use load the photo's to the iPad so i could view them and sort out any bad ones. then copy them over to the storage device so i can continue using my CF cards for shooting. I have an image thank for copying the photo's directly to the HDD but it would be so sweet to be able to check them on the iPad before hand.
any suggestions?

Check out pogo plug device, it allows you to upload camera roll via wifi.

Data guard setup for 2 node RAC primary to 2 node RAC standby

Hi All,
I am going to setup data guard for 2 node RAC primary to 2 node RAC standby on Oracle 10.2.0.4. in AIX5L.
Can you please provide the document on the above setup which is having all the steps (details).
Also, the documents on different scenarios like
1) If one node of standby goes down, how the redo logs will be applied. IS there any problem?
2) If both nodes of standby are failed, how to reciver them?
3) If one node of primary fails, is there any issue?
4) If two nodes of primary fails, is there any issue?
Thanks in advance,

Facing problem while using JDBC Storage option in FileStoreProvider

HI all,
We are using oracle 11.1.1.6.0 version and 11.2.0.1.0 of Oracle Database 11g Enterprise Edition.
In order to use the JDBC storage option , we are follwing the below steps:
1. On your Content Server instance, install and enable the FileStoreProvider component.
2. Configure FileStoreProvider to create a JDBC storage rule as desired.
3. Upon restart of Content Server, FileStoreProvider will create the table to store files.
4. Log into the database instance for Content Server
5. Drop the filestorage table created by FileStoreProvider (which uses Basic LOBs)
6. Recreate the filestorage table to leverage SecureFiles.
Here is a *sample*
CREATE script: CREATE TABLE filestorage ( DID number(38), DRENDITIONID VARCHAR2(30), DLASTMODIFIED TIMESTAMP(6), DFILESIZE NUMBER(38), DISDELETED VARCHAR2(1), BFILEDATA BLOB, CONSTRAINT PK_FILESTORAGE PRIMARY KEY (DID, DRENDITIONID)) LOB(BFILEDATA) STORE AS SECUREFILE TABLESPACE ;
Now when we checked in a new item in the content server, the details of the content is not getting updated in the DB.
Please provide your inputs. Do we need to do any other configuration changes?
Thanks in advance,

Could you please specify what you mean by "the details of the content is not getting updated in the DB"?
Does it mean that the checkin service fails? Or, it succeeds (you can verify from gui that both metadata and content were updated), but you cannot find updates in the database?
