Tell me that in Oracle 11g, information regarding voting disk location is stored in which file ?
I know that we can use "crsctl query css votedisk" to see the location of voting disk, but from which file or place this command pick the information ?
I have 2 servers both having windows server 2008 64 bit as operating system installed on both I need to install oracle clusterware 11g r1 on both servers with clustering on external storage. I have configured the network(private,public and virtual) for both servers and have started the installation.
In the installation of oracle I add both servers but then I reach to a point where they ask me for voting disk or ocr disk in the cluster configuration storage but no disk is present how can i create ocr disk or voting disk on windows server 2008? And the external storage should I buy a special type of storage that supports clustering to continue my work?
I am installing Oracle Grid Infratructure 11.2.0.3 on OEL 6.3...I reached the final step, running the root.sh on node 1. It succsessfully started the services but then I got this error:

Change to configuration failed, but was successfully rolled back.

OCR_VOTING Diskgroup is configured using oracleasm:

Here is part of logfile of the root.sh - tool. Meanwhile I tried deinstalling the clusterware and cleaning up, then I verified the server configuration with cluvfy and all was OK.

I gone through many forums and found that the number of voting disks should be always in odd number. Then why the maximum number of voting disk is 32?
View 1 Replies View RelatedI have DB on cluster and it set to active/active. ASM disk currently using raw device and connect to SAN storage. So i want to add new ASM disk on current environment.
Does oracle have this doc? What i can see from their said just show adding new ASM to new installation. Does it same as adding new ASM disk to current system? Does it success on implementation?
Normally if node fails, VIP & resources are transferred to another node (clients need to failover).
if node is back again CRS detect this, make it as 'family member' and try transfer VIP & resources back to this node (clients will force to failover again).
this failover (despite of failover method I use) make each uncommitted transaction to be rolled back. client need to be disconnected from the service and VIP through they are connected to this service and they need reconnect to the new node - during this stage all DMLs modifications are gone, and need to be re execute.
We are about to undertake a storage migration of our RAC environment from EMC to XIV storage.
The migration method we are using means that we will be presented with identical disks post the migration, however the UNIX paths to the disk devices will be changing. Using our migration method it is not possible to present the old and new devices at the same time.
Therefore once the migration is complete i need to update the device configuration to reflect the new paths. I believe this is done using the following techniques but I am unsure as some of the documentation is ambiguous and I have not done this before
Changing path to Voting Disks
crsctl add css votedisk <new_path_to_disk> -force
crsctl delete css votedisk <old_path_to_disk> -force
Changing path to OCR Disks
ocrconfig repair ocr <new_path_to_ocr>
ocrconfig repair ocrmirror <new_path_to_ocrmirror>
Changing paths to ASM disks
alter system set asm_diskstring='<new_device_path>' scope=both;

We have taken export expdp backup from prod database (primary database- Data Guard).
1.) Import impdp is very slow 10GB/Hrs on staging database (Data Guard MAXIMUM AVAILBILITY)Since Server configuration, database version and configuration, operating system everything are same as production. No blocking, locking or waiting sessions
2.)import impdp is fast 90GB/Hrs on Test standalone database and this test database is running in NOARCHIVE LOG mode with oracle standard version after that no more difference.
CPU,Memory,network and disk I/O are look normal while importing on both databases.why that much difference on import.
We have a Production Oracle 10g R2 RAC on HP-UX v2 IA64 servers.We have Two Disk Groups one for Archive (ARC_DISK - 100 GB) and other for Database(DATA_DISK - 1 TB]. We wanted to add more space to the DATA_DISK disk group.Unix admin configured 200 GB from SAN and changed the ownership of the Disk to oracle and permissions to 775 on 1st Node.I opended DBCA from 1st Node and was able to see the disk in 'Show Candidate'.
I added this disk to the DATA_DISK disk group and clicked OK but got ORA- error with some message like some operations could not be performed. I exited DBCA.We realized that we had forgotten to change the ownerhip and permission from the 2nd Node.Unix admin changed the ownership of the Disk to oracle and permissions to 775 on the 2nd Node.
I opened DBCA again from 1st Node and selected the DATA_DISK disk group but could not find the Disk in 'Show Candiate' open. I clicked on 'Show All' and this disk was shown with Header_Status - MEMBER but not allocated to DATA_DISKGROUP. When I clicked the 'Show Member' option, this disk is not shown for DATA_DISK disk group. I exited DBCA at this point.As this is a critcal Production database I didnt proceed any further and exited DBCA.
Now I need to add this Disk to the DATA_DISK disk group but not sure which option to select. I got one reply from another forum to run DBCA select the DATA_DISK Disk Group and then click 'Show All' and select this Disk (which already has MEMBER as Header Status) and select Force Option and click OK to continue.
I Configured an ASM instance and a disk group with two disk for normal redundancy.
> Here .. each disk is 2gb
The disk group has two disks...
SQL> select group_number, name, type, total_mb, free_mb
2 from v$asm_diskgroup;
GROUP_NUMBER NAME TYPE TOTAL_MB FREE_MB
------------ ------------------------------ ------ ---------- ----------
1 DATA NORMAL 4000 3898
as the group has two way mirroring (Normal redundancy) How much data (2 GB or 4 GB) can i keep in the disk group? My conception is I can keep 2 GB data in the disk group... (as the disk group keeps every extent in another disk as mirror)
what is difference between "ocrconfig -export location" and "ocrconfig -manualbackup location"
View 1 Replies View RelatedAbout the concept of quorum failgroup ORACLE says:QUORUM disks, or disks in quorum failure groups, cannot contain any database files,the Oracle Cluster Registry (OCR), or dynamic volumes. However, QUORUM diskscan contain the voting file for Cluster Synchronization Services (CSS). Oracle ASMuses quorum disks or disks in quorum failure groups for voting files wheneverpossible.
To sum up, i think the different between a regular failgroup and a quorum failgroup is a quorum failgroup can only contain vote files and a regular one can contains multiple kinds of files.So i didn't see any advantage to place voting files on a quorum failgroup than on a regular one. Why Oracle introduce the concept of quorum failgroup?
I've looked in several places, OTN, Google, various DBA forums to figure out if the way we have a client installed on a network drive is supported by Oracle - short of asking them if it's supported.
The configuration we have is a full 10g R2 client installed on a network drive, and the various environment variables (Oracle_Home, TNS_ADMIN, etc.) point to that network location for use by client machines (I'm also trying to see if the Instant client is supported on a network location as well.) We've had this set up for years which has served us well.
A co-worker remembers years ago that this set up wasn't supported, Oracle 8 or so was his thought as to what version was used then. Another coworker at an Oracle conference asked this same question and was told that it was supported, however we can't find any documentation to that effect.
Now the question arises as to whether or not using a client installed on a networked drive is a supported configuration for 10g R2 or higher, and if so, where it would be documented.
We are in the process of changing network topology and are reviewing whether this configuration is still the right thing for us or if clients should be installed locally to where they are used.

View 1 Replies View RelatedI understand the architecture of solid state drives favor different types of I/O. Oracle 11g introduced the database flash cache which allows flash storage to be used as a secondary cache. With database flash cache serving as a secondary cache to my Oracle buffer cache.
My understanding is I need to config two database parameters DB_FLASH_CACHE_FILE and DB_FLASH_CACHE_SIZE. If i want to have certain tables/indexes to take advantage of this extra cache I would set the value KEEP within the parameter.
Is there anything that needs to be done to the tablespaces / datafiles.

View 5 Replies View RelatedThe block size of my db(10gr2) is 8k, and the db is on the raw device file system on a aix machine.
OS block size is 512k.
How much block will be read from disk when a single oracle io call occurs? Which one is currect, 8K or 512K?
If the block size for a single io call depends on the os block size (512k), I think os block size need to be tuned for oracle block size (8k). If we use raw device file system, os level block size has no meaning?

I am unable to understand where is the problem.
We have 2 servers running Oracle 11gR2 Window server 2008 64 bit RAC. Today I add new shared disk visible from both servers. All our data placed on ASM partitions, but we need Windows volume for exchanging some data between servers & users;Actions:then i have prepare disk on shared storage from 1st node, run diskmfmt.msc & rescan disks when windows recognizes new hdd, initialize it.create an Extended partition & Logical drive & Assign drive letter. from another nodes, make sure no drive letter is assigned.
Sometimes Windows automatically assign drive letter. If drive letter is assigned, right click & Change drive letter & Remove. from 1st node, format this logical drive using ocfsFormat.exe after execute below scripts i have face some issues
E:app11.2.0gridcfs>ocfsformat /m P: /c 1024 /v DATA /f /d /aReg Get Cluster Name(): Reg Query ValueEx for CFS_CLUSTER_NAME failed with error 203
This indicates that the Cluster Name has not been configured on this node for OCFSThe volume formatted in this condition will be seen by all nodes running OCFS.
I am having 2 data centers within 1/2 km distance. And we kept each vote disk in once site. In case of site failure, the cluster needs a 3rd set. We don't have 3rd site.
Last open world, Oracle announced that oracle storage on cloud as announced. If I get the small space on the cloud, can i put my 3rd vote disk on the cloud?
