During ASM Disk Groups creation after the ASM instance creation, receive the following error: Disk Group ORAASMGROUP2 already exists. Cannot be created again
The Grid infrastructure was deinstall one time and still the same issue.
I am not able to find any document that shows steps to create a SINGLE INSTANCE LOGICAL STANDBY database for a 2 NODE ORACLE RAC database. I have found documents for RAC to Single Instance Physical standby database. But not for Logical Standby.
Details:
OS: Redhat 5
DB: 10.2.0.4(shared file system, not using ASM/Standby also file system)
Status: Single instance physical standby database created, need to convert it to Logical standby.
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?
We have a big problem in the underlying devices that ASM disk groups depends on. We have SAN disks (EMC DMX) presented to us as /dev/sda, /dev/sdb, etc.These disks have actually multipath setup. For example, - /dev/emcpowera has two different paths as:
1./dev/sda
2./dev/sdp
We were using the direct path /dev/sda to format the disk (as fdisk /dev/sda), and then used oracleasm to create disks (oracleasm createdisk ASMDISKDATA0 /dev/sda1). Then, ASM disk groups were created with those lables (volumes), and then database was created using the ASM disk groups.
Now our platform folks are telling us that we should use the multipath /dev/emcpowera instead of direct path /dev/sda as the direct path is not guaranteed across reboot.
So the questions are:
1.Is there a way to re-link the disk group to asm disk to the multipath devices (/dev/emcpowera1 instead of /dev/sda1)?
2.Is this even an issue for ASM? If the /dev/sda fails after reboot, can Oracle ASM automatically discover the other path /dev/sdp to the physical EMC disk?
My context on our servers is the following one:
- one ASM instance
- X DB instances
- each DB instance uses 2 or more dedicated diskgroups from the ASM instance
- there is one diskgroup named FREEDISK that contains spare disks
On each DB instance you can see:
- the list and global parameters of all diskgroups using v$asm_diskgroup view
- the list and parameters of all disks the instance is using with v$asm_disk view
So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?

I have a quiet large table (around 140 GB) and i want to create an index on it. I was wondering, before i fire my my create index statement, i know in advance how long will it take to complete? I know after the create index is executed, we can monitor and gets some estimates from longops view. but is there any way we estimate before hand?
Also my database is in archive log mode and what would be the fastest way to create an online index?

I have two tables having same name in two different databases.i have to create a new table with these two tables in a new database.
But if one table have 2 columns and another table having three columns I have to create a new table with three columns..
i had small query on external tables. i had (.csv) file outside the database. In this file, one column will be added monthly. i need to create the external table dynamically by adding the column for every month.
How the procedure can be created for this requirement.

I have window7 OS, I installed 4 ORACLE HOME's in WINDOWS7 machine,
two ORACLE_HOME is for 10.2.0.3
two ORACLE_HOME is for 11.2.0.2

creation of Listener for 10.2.0.3 ( first ORACLE_HOME)
but while creating listerner for 10.2.0.3( seconde ORACLE_HOME)

A am new in RAC configuration.I configuring RAC with ASM diskgroup with the external redundency. So now i am facing problem to mount the ASM diskgroup. I am giving the the RAC configuration description below.
1. using two node rac1 and rac2
2. asm disk configuration 3 drive
/dev/raw/raw1
/dev/raw/raw2
/dev/raw/raw3
on both node
3. and i am using vmware to configure the both node asmdisk group
after configuring the os level and oracle clustring , i run dbca to configure asm disk group..so in the create disk screen i have found my previous create 3 disks
/dev/raw/raw1
/dev/raw/raw2
/dev/raw/raw3
so first two disks
/dev/raw/raw1
/dev/raw/raw2
i named it "dg1" then press ok , when i pressed ok a warring is appear that is "could not mount the diskgroup on remote node on rac2 using the connection service rac2:1521:+ASM2. Ensure that the listener is running on this node and the asm instance is registred to the listener. Receive the following error:
ORA-15032 : not all alterations performed
ORA-15063 : ASM discovered insufficient number of disk for diskgroup "DG1"
as the same way i create another diskgroup "fg" for flash recovery area using disk /dev/raw/raw3
so after creating the two diskgroup i saw the two diskgroup is appere in the "diskgroup appere screen" an saw that only one diskgroup is mounted but not second node i.e. rac2 diskgroup is not mounted . What should i do no .
