How To Create Ocr Disk Or Voting Disk On Windows Server 2008
Feb 17, 2011I 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?
Server Administration :: Disk Group With Two Disk For Normal Redundancy
Jan 16, 2013I 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)

Server Administration :: How To Add Disk To ASM Diskgroup
Jun 7, 2011Resize 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
/dev/raw/raw10 /dev/cciss/c0d1p12
[code]....
how to do continue after step 5.
Server Administration :: 10g Change Disk With Datafiles
Nov 17, 2011What is best practice to change small disk D:? I am beginner with Oracle. 10g on W2008. 5 datafiles (all indexes,second data file, 2 undotabs)*.dbf (34;30;1;34;12 GB) is on D:. Part of tablespaces (1 data, 1 undo)has files on c:.
I.
1.Shutdown 2008 server.
2.Copy D: image with GHOST to USB, network.
3.Connect new D, create RAID.
4.Restore image to D.
5.Start 2008 server.
II.
1.Stop application.
2.CONNECT AS SYSDBA
3.SHUTDOWN NORMAL or (IMMEDIATE)?
4.Copy files *.dbf at OS level from d: to ... USB disk, network.
5.Shutdown 2008 server.
6.Change disks, create RAID in BIOS.
7.Start W2008.
Is Oracle at this moment in SHUTDOWN mode?
8.Copy back *.dbf to new D: (with directory structure).
9.STARTUP Oracle.

View 2 Replies View RelatedServer Administration :: ASM - Disk Strategies In Production Environments?
Jan 26, 2010I am working on ASM as i am bit confused to decide ASM Disk strategies in production Environments. For Ex:-
1.Normal Redundancy ( Allows 2 Mirror Groups ) :-
I have created Normal_DG Diskgroup with 4 Disks
Disk1-------------------
Disk2 ------- |
|--->FG2 ----> FG1
Disk3 ------- |
Disk4-------------------
According to my understanding , if Disk1 Fails Disk4 facilitates normal operations. When there is space crunch it operates in reduced redundancy . Am i right ?
2.I have got 4 Disks in one group (i.e from Disk1 To Disk4 ) i have not defined any failure group and as per my understanding all disks will be added to its own failure group without mirroring and striping.
Server Administration :: ASM / Dropping A Newly Created Disk Group?
Apr 6, 2012I was setting up disks groups and I accidentally created one group (DATA) with "NORMAL" redundancy but wanted it to be "EXTERNAL". I tried using asmca to remove disks from the group, drop the group, change the redundancy..... All of this failed because there was an spfile on the disk group.
I finally got it to work with using this procedure:
sqlplus '/ as sysasm'
SQL*Plus: Release 11.2.0.3.0 Production on Thu Apr 5 08:58:19 2012
Copyright (c) 1982, 2011, Oracle. All rights reserved.
SQL> drop diskgroup DATA;
drop diskgroup DATA
*
ERROR at line 1:
ORA-15039: diskgroup not dropped
ORA-15053: diskgroup "DATA" contains existing files
[code]....
In summary, I am not sure why changing the redundancy would be so difficult if there is data on the disk group.
Server Administration :: Reclaiming Actual Physical Disk Space?
Sep 3, 2011essentially create data fragmentation within the datafile resulting in the db having lots more space to write into but not actually freeing space, even if you shrink the file it doesnt free space or do a reorg?
We have as an example a DB with 2 billion rows of data in 1 table, no partioning just one large table.
We have worked out that we can probably delete 1 billion rows or even better only keep a rolling 3 month window of data.
What would be the suggestion on deleting this data and reclaiming the disk space to actually see additional disk space made available at the os level.
deleting the data and reclaiming the space.
Through reading it looks like it might be something like, delete, creating new table space partitions from this data. This in theory would create new a tablespace in newly created data files which would result in the data being reorganised and taking up less physical space and when completed you point to the newly created partitions and drop the old tables.

Server Administration :: Multi-block Disk Reads For Index Range Scans?
Aug 31, 2010My understanding of DB_FILE_MULTIBLOCK_READ_COUNT parameter is that it affects only Full Table Scans and Fast Full Index Scans - all other disk retrieval is single block.If so, then maybe I'm reading this trace incorrectly:
select /*+ first_rows */ pk
from test_join_tgt
where pk >= 0
and rownum > 1
call count cpu elapsed disk query current rows
------- ------ -------- ---------- ---------- ---------- ---------- ----------
Parse 1 0.01 0.00 0 0 0 0
Execute 1 0.00 0.00 0 0 0 0
Fetch 1 21.48 27.77 22368 22134 0 0
------- ------ -------- ---------- ---------- ---------- ---------- ----------
total 3 21.49 27.78 22368 22134 0 0
[code]...
What the heck is going on with the Multi-block reads in the Range Scan?
Server Administration :: Any Relation Of Tablespace Disk Space And Actual Data Present In Tables
Aug 16, 2012We are using Oracle 10g and have 10 tablespaces defined for our Database which have 108 tables. Size of 108 tables is around 251 MB as seen during importing the dump. While creating these 10 tablespaces I used below parameters for allocation of space
SIZE 1M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE 1M;
which set the initial space for 10 tablespaces to around 1032Kb each. Now my Question is after importing the dump , how the disk space for 10 tablespaces increases to 398 MB in total ?
Is there any relation of Tablespace disk space and Actual Data present in the tables ?
Server Administration :: How To Get Disk List On Any DB Instance That Uses ASM Instance
Mar 16, 2011My 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?
Create ASM Disk Using OracleASM

Looks fine, but the ASMCMD doesn't listing it...

/dev/oracleasm/disks/DISK2
And the V$ASM_DISK can not...

Windows :: Create ASM Disk Did Not Recognize Unallocated Partition
Jan 21, 2012This is the first time I've got a job in Windows platform, I've worked as DBA with Unix/Linux still now.

And, when I install 11gR2 Grid, the step ASM creation did not recognize the Unallocated Partition I created.

View 1 Replies View RelatedPerformance Tuning :: Create Statements On A Highly Fragmented Disk
Nov 24, 2010On Oracle 10g, I create, delete and drop a lot of tables. Therefore, the disk is highly fragmented.The execution of a very simple create statement takes more than a minute. If I execute the same statement but first truncate the table and insert the data, it takes less than a second!
I think this has to do with the high fragmentation of the disk. Obviously, I can defragment the disk, but I will always have a high fragmentation since I use a lot of create, delete and drops.
how I can improve the performance of create statements on highly fragmented disks?
