Database creation with ASM using dbca

Question

hi all,
i found the steps to create the database using ASM diskgroup.
but i received errors when configuring the FRA(flash recovery area), DBF(normal), +ARCH(archival dest),
i tried atleast 2 to 3 times from scratch but found the same error....................
ORA: 19624
ORA: 19870
here are the steps can somebody correct these steps..................
Create Virtual Disks from VM Ware software when server is down.
Choose Edit Virtual Machine Settings.
Click on Add button
Press Next and Highlight Hard Disk, then click Next
Check ‘Create a New Virtual Disk’
Choose SCSI as type
Select Size as 2 GB
Name the virtual disk as ‘ASMDBF1.vmdk’
Create additional disks as:
ASMDBF1.vmdk for DBF files
ASMDBF2.vmdk Failover group
ASMFRA.vmdk Flash Back Recovery Area
ASMREDO.vmdk Redo Log Area
ASMARCH.vmdk Archived Logs
•     Start up the server OraWorld1
•     Go to Disk Management and you will be prompted with a screen which should display all five disks with a check mark. Accept defaults and Click next.
•     On second script all five will be unchecked, click Next
•     Press Finish to complete and you should see all 5 disks as Type Basic Unallocated. For each of the disk perform:
1.     Right click, New Partition, Extended Partition and Finish
2.     Right click, New Logical drive, Do not assign drive letter nor partition it.
3.     From command prompt type Diskpart and enter Automount enable.
4.     From command prompt, configure basic CRS services as
5.     C:\oracle\product\10.2.0\db_1>localconfig add
6.     C:\oracle\product\10.2.0\db_1>localconfig add
7.     Step 1: creating new OCR repository
8.     Successfully accumulated necessary OCR keys.
9.     Creating OCR keys for user 'administrator', privgrp ''..
10.     Operation successful.
11.     Step 2: creating new CSS service
12.     successfully created local CSS service
13.     successfully added CSS to home
•     Launch DBCA and choose Configure Storage Management.
•     Select Create New group, choose stamp disks which will show you all of your five disks. Configure ASM links to all these disks as:
1.     ORCLDISKASMDBF1 \Device\Harddisk1\Partition1
2.     ORCLDISKASMDBF2 \Device\Harddisk2\Partition1
3.     ORCLDISKASMFRA \Device\Harddisk3\Partition1
4.     ORCLDISKASMREDO \Device\Harddisk4\Partition1
5.     ORCLDISKASMARCH \Device\Harddisk5\Partition1
Now make Change Disk Discovery Path as Null and you should see all disks.
Now create Disk groups as :
ARCH \\.\ORCLDISKASMARCH External 1GB
REDO \\.\ORCLDISKASMREDO External 1GB
FRA \\.\ORCLDISKASMFRA External 2GB
DBF (MAIN GROUP WITH 2 SUB-GROUPS) Must create as Normal Redundancy
DBFP \\.\ORCLDISKASMDBF1 External 2GB
DBFS \\.\ORCLDISKASMDBF2 External 2GB
You now have a running ASM instance on the server.
•     Checking ASM instance
You can always use DBCA to check settings of ASM.
Alternatively, go to command prompt:
Set ORACLE_SID=+ASM
Sqlplus /nolog
Connect sys/password as sysdba
Show sga (80MB)
Total System Global Area 83886080 bytes
Fixed Size 1247420 bytes
Variable Size 57472836 bytes
ASM Cache 25165824 bytes
SQL>desc You can then check C:\oracle\product\10.2.0\db_1\database for these files. You can also view v$parameter for all possible values for ASM instance.
+asm.asm_diskgroups='DATA1','ARCH','REDO','FRA','DBF'#Manual Mount
*.asm_diskgroups='DATA1','ARCH','REDO','FRA','DBF'
*.asm_diskstring=''
*.background_dump_dest='C:\oracle\product\10.2.0\admin\+ASM\bdump'
*.core_dump_dest='C:\oracle\product\10.2.0\admin\+ASM\cdump'
*.instance_type='asm'
*.large_pool_size=12M
*.remote_login_passwordfile='SHARED'
*.user_dump_dest='C:\oracle\product\10.2.0\admin\+ASM\udump'
You can change some of the values like large pool and even db cache size. You can also manually create the disk group as:
Create diskgroup DBF NORMAL redundancy
Failgroup flgrp1 disk ‘\\.\ORCLDISKDATA0’, ‘\\.\ORCLDISKDATA1’
Failgroup flgrp2 disk ‘\\.\ORCLDISKDATA2’, ‘\\.\ORCLDISKDATA3’;
Check Candidate disks:
select group_number, disk_number, mount_status, header_status, state, path from v$asm_disk;
Other useful queries:
Select group_number, name, total_mb, free_mb, state, type
From v$asm_diskgroup;
Select group_number, disk_number, mount_status, header_status, state, path, failgroup
From v$asm_disk;
You can use sql commands to perform most of the ASM tasks, however EM console can also be used here
Oracle Database Installation
•     Launch DBCA
•     Choose Create Database and select OLTP type
•     Name it as ORCL2, choose ASM as file system, select all disk groups to be used.
•     Use oracle managed files as:+DBF press Next
*•     Specify Flash Recovery Area as +FRA*
*•     Enable archiving at +ARCH*
*•     Choose Auto SGA as 55% of memory*
*•     Leave else default and complete DB creation.*
*•     Launch NetConfig and define Listener with default settings.* here i received the errors,.................
Database ORCL2 is created with the following attributes:
NAME: ORCL2
SPFILE: +ARCH/ORCL2/spfileORCL2.ora
URL: http://oraworld1:1158/em

Answer 1

Strange, those messages are RMAN backup errors -- are you trying to backup the database?
Or...if you selected "create starter database" it may be that dbca is not finding the backup files from the "demo" database.
