Db flash cache file on ASM for RAC

Dear guys/gurus,
I am installing RAC 11.2 on Solaris 10 sparc. After RAC intallation finish i want to do the db flash cache.
On each node, i have 4 SSD Disk and want to create 2 diskgroup FLASH1 on node1 and FLASH2 on node2 for db_flash_cache_file
inst1.db_flash_cache_file=+FLASH1/flashfile01
inst2.db_flash_cache_file=+FLASH2/flashfile02
The question is, in RAC how can i create a local diskgroup example FLASH1 is only mount on node1 and the same for FLASH2. Because when the database startup it try to mount FLASH1 on both node, also FLASH2 and thrown an error if node 2 can not see +FLASH1.
Please advise, So thanks and best regards
Ch

Hi Sharma,
RAC and DB version is 11.2.0.2. Yes, as you said, it may involved in hard dependency
When i start db the error come : Unable to start ‘ora.dbvn.db’ because it has a ‘hard’ dependency on ‘ora.FLASH1.dg’
./crsctl start res ora.dbvn.db –p | grep DEPENDENCIES
START_DEPENDENCY=hard(ora.DATA.dg,ora.ARCH.dg,ora.REDO1.dg, ora.REDO2.dg,ora.FLASH1.dg) …

How to create redlog and control file at ASM in linux RAC

Hi Experts,
I will to maintance a oracle 10g database at ASM as RAC iin linux red hat.
i am a new person with some question.
nornally speaking, oracle recommadition for oracle 10g database as
create 3 copy fills for control file
create at least 2 redo log with mirror files in system.
However, I checked find
redlog file is at FRA place +FLSdisk1 and no mirror
control file is at FRA place--+FLSDISK1/
datebase file at ‘+DATA1/
There are no mirror for relog.
Go to EM, I also could not find place to enter file name.
We use ASM to hold database to support RAC.
Do i need to create redlog file as
ALTER DATABASE ADD LOGFILE GROUP 1 ('+FLSdisk1/sale/onlinelog/REDO01.LOG','+FLSdisk1/sale/onlinelog/REDO01_mirror.LOG') SIZE 1000M reuse;
my boss told me that ASM is reliable.
Do you need to creat more directory to arrange redlog and control files in ASM for RAC system?
FRA is a good place to store control file and redlog file ?
Thanks
JIM

ASM is reliable but a smart DBA is very careful. If ASM is doing mirroring this is like RAID doing mirroring. What happens if you accidentally delete one copy ... the other one disappears instantly. Not a good idea.
With respect to redo logs you need a minimum of three groups, two members, and one thread per instance. So a 2 node cluster should, at a minimum have 12 physical files.
Not mirroring the redo logs, assuming multiple members, is not as critical.

How to add other 2 control files at ASM in linux RAC

Hi Experts,
I am new for RAC .
the vendor build a RAC for us. I found there are only one control file in system.
we use oracle 10.2.0.4 at ASM with RAC in redhat linux 5.
how to add 2 additional control file to ASM for RAC ?
Please provide a procedur in detail.
Thanks

Hi damorgan & Friends,
I could not find some infomration to add control into ASM . I can do this job( see below procedure) in no ASM .
My question, our database locates at ASM and control file with a system auto-number ( fully qualified filename ) as

How do I physical copy and rename other 2 contril file in directory and modify location in pfile?
I saw some paper to use request as an alias (such as +dgroup2/control/ctl.f). i can not image to copy/rename control.
Please help me!!
Thanks

Need RAC/ASM multinode flash cache configuration advice

We have a working two-node RAC database. We are installing a new 640gb fusion flash card in each node. The card is a double-card, so that it shows up as two devices: /dev/fioa and /dev/fiob on each node.
We have created two private disk groups, one on each node. The disk group on node 1 is "+FLASHCACHE" and the disk group on node 2 is "+FLASHCACHE2".
We haven't found any specific examples of how to configure the init parameters for flashcache on RAC/ASM. We are guessing that we should do the following. If someone would critique and confirm or suggest something different, we would appreciate it very much!
prod1.db_flash_cache_file='+FLASHCACHE/flash1'
prod2.dg_flash_cache_file='+FLASHCACHE2/flash2'
*.db_flash_cache_size=600G
Thanks for any advice.
Jim

Hi Jim,
prod1.db_flash_cache_file='+FLASHCACHE/flash1'
prod2.dg_flash_cache_file='+FLASHCACHE2/flash2'
*.db_flash_cache_size=600GYour configuration is correct.
Database Smart Flash Cache is not shared across RAC nodes; it is private to each RAC instance. For that reason, each RAC instance must define its own local flash cache file path. When the flash cache is managed by ASM, a separate diskgroup is needed for the flash cache of each instance.
You can use ALTER SYSTEM to set db_flash_cache_size to zero to disable the flash cache. You can also use ALTER SYSTEM to set the flash cache back to its original size to reenable it.

How many control file should be created in ASM for ORACLE 4 nodes RAC

We have a oracle 10G(10.2.0.4) database with 4 nodes locates ASM in redhat linux5.
The vendor created this RAC system with database.
I saw below infornation as
SQL> select name from GV_$CONTROLFILE;
NAME
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
It seems that each node with one control file.
I got a feedback that vender claimed SAN is very reliable.
I am new person for database at ASM for RAC.
Could you make a explain for this condition? Do I need to add ( mirror) another 2 control file into ASM?
The Oracle recommands that at least 2 contril files( best 3 files) in different place. This is true for signle instance.
How about RAC that database locates in ASM?
Please help me!!
Jim

You are fine using the standard three controlfiles in ASM, four is fine too, but it does not need to be tied to the number of instances as all the instances in a RAC database use the same controlfile (and its copies). ASM knows the controlfile type and will stripe each one in 128k pieces across as many volumes as it can. I much prefer to have my controlfiles in ASM, it prevents accidental deletion and generally makes DBA life easier.

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!

Premiere hangs when it cant find cache files

Hi all,
My question:
How do I force premiere to open my projects without searching endlessly for cache files?
If this cant be done:
What is the best way to create a network based central cache folder from which multiple users can draw from. (the problem of course is the potential for this file to grow exponentially)
Background
9 times out of 10 when I attempt to load my premiere projects off the network, the load bar will reach just about 95% and hang for an eternity. We have identified that our company bandwidth was getting a bit overloaded but I think another issue has reared its ugly head.
Our company stores all premiere files and related footage on the network to allow for easy access from many users. However, when a user who did not create a certain project attempts to open it on their desktop, the same loading problem comes up. It appears that if I push my cache files to the network, point premiere to that folder, the file loads rather quickyl (indexing aside).
So can I force premiere to give up on a hopeless search of the local computer for cache files and if not, how can I create an organized system where many users can pull from the same cache folder. You will notice, if i simply create a central folder the following will take place:
The folder will grow
I will have to wipe it
files will stop loading while premiere desperatly attempts to find non existant cache files.
Thanks for your help.

How to organize RAC database files on ASM

How to Organize RAC database files on ASM.
Say,
DISK Group = DATA
DISK Group= FLASH
Instance = prod1, prod2
'+DATA/PROD/datafiles/'
or
Need to Organize sepratly for each instance specific db files.
as
'+DATA/PROD1/datafiles'
'+DATA?PROD2/datafiles'
Thanks in Advance,

It would be just PROD - since that's the database name...and BTW, when you use DBCA to create a database using ASM, it organizes data files under PROD and it doesn't use instance names.

Linux Cluster File System partitions for 10g RAC

Hi Friends,
I planned to install 2 Node Oracle 10g RAC on RHEL and I planned to use Linux File system itself for OCR,Voting Disk and datafiles (no OCFS2/RAW/ASM)
I am having SAN storage.
I would like to know how do i create shared/cluster partitions for OCR,Voting Disk and Datafiles (common storage on SAN).
Do i need to install any Linux cluster file system for creating these shared partitions (as we have sun cluster in solaris)?
If so let me know what versions are supported and provide the necessary Note / Link
Regards,
DB

Oracle10g RAC with ASM for stretch cluster

Assuming suitable network between sites is in place for RAC interconnect (e.g. dark fibre / DWDM), does it make sense (or is it possible) to stretch a RAC cluster across 2 sites, using ASM to mirror database files between SAN storage devices located at each site? The idea being to combine local high availability with a disaster recovery capability, using hardware that is all active during normal operation (rather than say a single RAC cluster on one site with Data Guard to transport data to the other site for DR).
Or, for a stretch cluster, would SAN / OS implemented remote mirroring be a better idea? (I'd have thought this is likely to incur even more overhead on the network than ASM, but that might be dependant on individual vendors' implementations).
Any thoughts welcome!
Rob

Cannot publish Flash Updates Verification of file signature failed for file SCUP 2011, SCCM 2012 R2 and WSUS all on same Windows Server 2012 machine

I am attempting to distribute Adobe Flash updates using SCUP 2011, SCCM 2012 R2, WSUS ver4 and Windows Server 2012. Everything installs without error. I have acquired a certificate for SCUP signing from the internal Enterprise CA. I have
verified the signing certificate has a 1024 bit key. I have imported the certificate into the server's Trusted Publishers and Trusted Root CA stores for the computer. When I attempt to publish a Flash update with Full content I receive the following
error:
2015-02-13 23:00:48.724 UTC Error Scup2011.21 Publisher.PublishPackage PublishPackage(): Operation Failed with Error: Verification of file signature failed for file:

I have redone the certificates three times with no luck. I can import metadata, but any attempt to download content results in the verification error.
TIA

Hi Joyce,
This is embarrassing, I used that very post as my guide when deploying my certificate templates, but failed to change the bit length to 2048. Thank you for being my second set of eyes.
I changed my certificate key bit length to 2048, deleted the old cert from all certificate stores, acquired the a new signing cert, verified the key length was 2048, exported the new cert to pfx and cer files, imported into my Trusted publishers
and Trusted Root Authorities stores, reconfigured SCUP to use the new pfx file, rebooted the server and attempted to re-publish the updates with the following results:
2015-02-16 13:35:44.006 UTC Error Scup2011.4 Publisher.PublishPackage PublishPackage(): Operation Failed with Error: Verification of file signature failed for file:

Is there a chance this content was already created and signed with the old cert, so installing the new cert has no effect? In ConfigMgr software updates I see 4 Flash updates, all marked Metadata Only (because they were originally published as "Automatic."
No Flash updates in the ConfigMgr console are marked as downloaded. I can't find any documentation on how the process of using SCUP for downloading content for an update marked Metadata Only actually works.
Comments and suggestions welcome.

I just found an error in the file name for my Camera Raw Cache file. How do I correct it?

I just found an error in the file name for my camera raw cache file. The error is in my username. I don't know how to correct the error or if I should just leave it. I'm not sure where my cache file is stored on my computer. Any help would be appreciated.
Thank you

Since you are on a Mac if when you first set up your account you left out the i in Wilson nothing you do will change that. The REAL account name will always be alicewlson. Once an account is created you can't actually change the name of it. You can change the name that is displayed but not the REAL account name.
Simplest thing to do is stop worrying about it. Everything is as it should be, that is except Wilson being spelled without the i.

Bridge cache files for different bridge versions

Bridge with CS2 and now CS3 is a superb image browsing tool - particularly when the cache files are within the directory containing the images. It would be very very useful if new versions of bridge could read older version cache files.
If a user creates cache files in a disk directory and then backs up the directory to a DVD for archival purposes, it would be very valuable to allow the "current version" of bridge to properly read the "old version" DVD archived bridge files. This would add greatly to the browsing speed of the DVD archive - since a new cache file will not be needed (or desired).
In addition, if previous versions of the cache files are on a hard drive, the ability to process the old version files would allow bridge to work more rapidly when browsing images. Of course, there are problems if the user attempts to update information that is version specific, however I am sure there are sane solutions to the problem.
tony

Not having to use a centralised cache was one of Bridge 1.0's strengths.
Not sure about the current versions insistence on centralising with the option of distributed as well or why the cache type as changed. A pain from an archival point of view as I used distibuted cache, which is now a waste of bytes.
