I have a question about the ADD VOLUME command, I can't understand the difference between ADD DISK and ADD VOLUME.What are the difference between them?When should I use each one?How can I control the stripping and mirroring (NORMAL and HIGH) adding VOLUMES in a DISKGROUP?Can I add a volume to a fail group?
View 1 RepliesWe 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)
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 have a query in oracle report in which i am getting this output.Manager Arnav have 2 employees Inder and kaushal whose salary is 10000 and 20000 respectively,
And another manager is Anjali whose employees are Kavya and inder whose salary is 40000 and 10000 respectively .as Inder is repeated I want the salary become 0 in place of 10000 second time.I am in dilemma,What should i do ,if i want to change 10000 to 0
Manager employee salary
Arnav Tiwari Inder 10000
kaushal 20000
Anjali Kavya 40000
Inder 10000[/b]
What should i do in the formula of salary.according to employee name .means if Name exists already then salary value should be 0 and if it comes for the 1st time then its actual value i.e 10000 should be printed.
I am in the very early planning stages of a project the goal of which is to identify separate organizations which may in fact be the same organization.
Our first implementation of this task was a process designed to look for a few thousand organizations in a pool of a few hundred thousand organizations. To accomplish this we made heavy use of Oracle's Text index as well as a custom index type we created which utilized n-grams. This approach worked quite well for on-demand editing of the organizations, in which a user might log in and say in addition to what we already know about organization A we also know x, y and z does that change anything and worked acceptably well for the bulk processing we did on our "known" information once a week running for a couple of hours on the weekend.
We have now been tasked with reworking this initial implementation only now we want to look at a set consisting of several million organizations for potential matches which exist within the set. As in our initial implementation we will be breaking what we know about organizations into groupings so we aren't comparing a phone number to an email address and normalizing the data as much as we can so we ignore things like case and punctuation. Even after all this we are still talking about looking for similar values in a group which might be in the tens of millions (some types of data will have more than one value per organization).
My initial thought on the problem is to use n-grams though not in the way we did in the past. The basic idea here is that we break the search values up into all the substrings it is made of and look for other values which have a high number of those substrings in common.
SQL & PL/SQL was the best place for the question, but I could not think of a better one.
I was asked by my systems administrator if I could tell him how much redo log volume, on average, do I figure we generate in a day?
Just wondering how I might calculate this?
We have several production databases. If I wanted to calculate the above for one of them, would it be take all the redo logs for a day and total up the size in bytes? Maybe take a 5 day work week and take the average over the 5 days?
We have Root disk on all the unix servers and is mirrored using SVM using the internal disks. Also VxVM 5.0 MP3 is used as the volume manager to manage the SAN space allocated to the servers. On some instances, SVM is also used for allocating filesystem for application and database
We are required to move all the files from SVM to VxVM.
In the process we are Copying our Oracle binaries from SVM to VXVM.I am planning to use the CPIO command to do the same.Once i move to VXVM (Veritas Volume Manager), i will bring down the SVM.
I need to calculate the redo log volume generated by certain tables. If I have 100 tables in the database I need to know only 25 tables redolog vloume per day. How I can calculate this , Is the log miner useful on this issue.

We have a new implementation which will be using ASM with RAID. The data area needs to be 3TB, and the recovery area, to be used for archive logs and RMAN backups, needs to be 1TB.
The configuration i'm thinking about now is:
+DATA diskgroup: 5*600G disks, using RAID 1+0 (this will include control files)
+FRA diskgroup: 2*500G disks, using RAID 1
+LOG diskgroup: 2*1G disks, using RAID 1 (this is only for redo logs)
So here are my questions:
1. Am I right in supposing that we would get the best performance on the +FRA and +LOG diskgroups by not using RAID 1+0?
2. It has already been agreed to use RAID 1+0 for the +DATA diskgroup, but I can't see the added benefit of this. ASM will already stripe the data, so surely RAID 0 will just stripe it again (i.e double striping the data). Would it not be the better just to mirror the data at a hardware level?
I just made the swich to have my RMAN backup directly to tape and here are the parameters I have set.
CODECONFIGURE DEFAULT DEVICE TYPE TO 'SBT_TAPE';
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE SBT_TAPE TO '%F';
CONFIGURE DEVICE TYPE 'SBT_TAPE' PARALLELISM 4 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE SBT_TAPE TO 1; # default
[code]...
When I do an active clone I need to set my parameters back to the following in order to makeit work.
CODECONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
[code]....
Instead of un-doing my RMAN TAPE settings, is there something I can do in my active clone script to tell it read/write from/to disk instead of tape. I tried allocatiing disk channels but was unable to get my script to work. The only way it worked was to back out all the tape settings and put everything back to disk.
CODErman catalog=rman/rman@prod target=sys/sys@prod << EOT
connect auxiliary sys/sys@dev

I 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?
We are running oracle 10g on a solaris system. We were taking the backup to the tape system previously. But the tape system is broken due to some reasons and cannot be used now. Now I am trying to take a rman full backup with archivelog to a NFS disk. The server in which the NFS disk lies is in Ubuntu. I have also considered that there is some problem with the NFS rman backup but can be solved by using hard and noac while mounting. Now I wanted to know is, what parameters should be changed to direct the backup sets to the new location in NFS instead of the old disk ? Do I need another media manager as in tape?

how to configure rman to backup to this location
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

Resize or add disk in ASM.
- The storage has partitions like:
- And now, the size of ASM disk was full
Because I've not ever done for adding disk to diskgroup.
Step 1- Format the storage, add partitions (I will create 4 partitions of 120gb, 1 partitions 60gb, 1 partitions 27gb).
Step 2- Add the rawdevice in /etc/sysconfig/rawdevices.In the picture here, I'll not just add rawdevice in /etc/sysconfig/rawdevices. So I'll do:
add lines in /etc/sysconfig/rawdevices
/dev/raw/raw7 /dev/cciss/c0d1p9
/dev/raw/raw8 /dev/cciss/c0d1p10
/dev/raw/raw9 /dev/cciss/c0d1p11

I 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.
