Exadata Database machine consists of 3 ASM Disk Groups:
+DATA for Database Files
+RECO for Online Redo log and Archive log files
+DBFS_DG for Cluster configuration files such as OCR and Voting disks

In a Customized environment Customers can choose to have more than 3 Disk Groups. But it is recommended to have 3 Disk Groups. The DATA and RECO disk groups can be sized 80%-20% or 40%-60% respectively of over all storage capacity. Sometimes it is possible that +DATA disk group can be filled very fast if you have several databases.

In this article we will demostrate how to move a Database from +DATA disk group to +RECO disk group.

Steps to move a database from +DATA to +RECO ASM Disk Group:

Step 1: Get the ASM Disk Information

SQL> select state,name from v$asm_diskgroup;

STATE NAME
———– ——————————
MOUNTED RECO
MOUNTED DBFS_DG
MOUNTED DATA

Step 2: Get the Database files details

SQL> select name, open_mode,database_role from gv$database;

NAME OPEN_MODE DATABASE_ROLE
——— ——————– —————-
DBM01 READ WRITE PRIMARY
DBM01 READ WRITE PRIMARY
DBM01 READ WRITE PRIMARY
DBM01 READ WRITE PRIMARY

SQL> select name from v$controlfile;

Oracle Database Appliance: Resize CloudFS ACFS File System Using ASMCA

By Netsoftmate on

August 8, 2018

- Uncategorized

During the Oracle Database Appliance Deployment you can optionally configure CloudFS file system. The default mount point is /cloudfs and set to default size of 50GB. Oracle Database Appliance uses the Oracle Automatic Storage Management Cluster File System (Oracle ACFS) for database and virtual machine files storage. ACFS can only be used to configure shared storage file system on ODA. Oracle ACFS provides both servers with concurrent access to /cloudfs shared file system. The default size of 50GB may not sufficient and must be increased to store big files for business requirement.

In this article we will demonstrate how to resize the /cloudfs file system using ASMCA GUI interface

Steps to resize the /cloudfs file system using asmca GUI Interface

Step 1: Get the current /cloudfs file system size

Step 2: Start VNC on node 1. Here I am starting VNC as root user. You can choose to start it as Grid or Oracle user.

[root@odanode1 ~]# rpm -qa *vnc*
tigervnc-1.1.0-18.el6.x86_64
tigervnc-server-1.1.0-18.el6.x86_64
[root@odanode1 ~]# ps -ef|grep vnc
root 23281 20754 0 13:32 pts/1 00:00:00 grep vnc

[root@odanode1 ~]# vncserver :1

You will require a password to access your desktops.

Password:
Verify:

New ‘odanode1:1 (root)’ desktop is odanode1:1

Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/odanode1:1.log

[root@odanode1 ~]# ps -ef|grep vnc
root 23399 1 1 13:32 pts/1 00:00:00 /usr/bin/Xvnc :1 -desktop odanode1:1 (root) -auth /root/.Xauthority -geometry 1024×768 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5901 -fp catalogue:/etc/X11/fontpath.d -pn
root 23481 23480 0 13:33 pts/1 00:00:00 vncconfig -iconic
root 23636 20754 0 13:33 pts/1 00:00:00 grep vnc

Step 3: Start VNC viewer on desktop and enter the hostname/IP address on node 1. Enter the root password as we have started the VNC server using root user.

Step 4: Switch to grid user and verify the Grid Home

Step 5: Set Oracle Home to Grid home and start asmca

Step 6: Click on ASM Cluster File System Tab

Step 7: Right Click on /cloudfs and select Resize option

Step 8: Enter the desired new size. Here I am resizing the /cloudfs to 200GB

Step 9: Resize in progress

Step 10: Resize completed

Step 11: Verify the /cloudfs size

Conclusion

In this article we have learned how to resize/increase the size of /cloudfs ACFS file system on ODA using ASMCA GUI utility. The cloudfs file system is configured during the ODA deployment and it is set to 50GB which is not sufficient for storing the big files. The cloudfs is build using ACFS and it can be resized easily using ASMCA graphical interface.

Oracle Database Appliance : Monitor Hardware Components

By Netsoftmate on

July 18, 2018

- Uncategorized

Oracle Database Appliance (ODA) is an entry level Engineered System. ODA is a pre-configured, highly available Oracle Database Engineered system. ODA system consists of hardware, software, storage and networking. The hardware configuration is designed to provide redundancy and protection against single points of failures in the system.

ODA consists of two physical servers (Node 0 and Node 1), a storage shelf and optionally an additional storage shelf. The two independent physical servers are interconnected and direct attached to SAS and SSD storage.

ODA is basically a 2-node RAC cluster database system running Oracle Linux operating (OEL), Oracle Database Enterprise Edition, Oracle Grid Infrastructure (Clusterware and ASM). All these together provides the Oracle Database high availability running on ODA.

ODA consists of several hardware components such as Mother Board, Processor, Memory, Power Supply, FAN, Network cards and so on. You can monitor the hardware status of these components using OAKCLI command for both Bare Metal and Virtualized platform.

Note: ODACLI is used for Hardware monitoring and administrative tasks on the Oracle Database Appliance on X6-2 S/M/L & X7-2 S/M.

In this article we will demonstrate how to monitor different hardware component status on ODA nodes.

Oracle Database Appliance: Resize CloudFS ACFS File System Manually

By Netsoftmate on

July 17, 2018

- Uncategorized

During Oracle Database Appliance Deployment you can optionally configure CloudFS file system. The default mount point is /cloudfs and set to default size of 50GB. Oracle Database Appliance uses the Oracle Automatic Storage Management Cluster File System (Oracle ACFS) for database and virtual machine files storage. ACFS can only be used to configure shared storage file system on ODA. Oracle ACFS provides both servers with concurrent access to /cloudfs shared file system. The default size of 50GB may not sufficient and must be increased to store big files for business requirement.

In this article we will demonstrate how to resize the /cloudfs file system manually using ACFS commands.

Steps to resize the /cloudfs file system

Step 1: Login to node 1 as grid user the owner of Grid Infrastructure software

[grid@odanoden1 ~]$ id
uid=1000(grid) gid=1001(oinstall) groups=1001(oinstall),1003(racoper),1004(asmdba),1005(asmoper),1006(asmadmin)

Step 2: Verify the existing size of /cloudfs. Here is my case the /cloufs is 200GB and it was resized in the past from 50GB to 200GB

[grid@odanoden1 ~]$ df -h /cloudfs
Filesystem Size Used Avail Use% Mounted on
/dev/asm/acfsvol-23 200G 483M 200G 1% /cloudfs

Step 3: Set the ORACLE SID to +ASM1

[grid@odanoden1 ~]$ echo $ORACLE_SID

[grid@odanoden1 ~]$ . oraenv
ORACLE_SID = [grid] ? +ASM1
The Oracle base has been set to /u01/app/grid

[grid@odanoden1 ~]$ echo $ORACLE_SID
+ASM1

Step 4: List the ACFS Mounts. Here we can see that /cloudfs volume is /dev/asm/acfsvol-23

[grid@odanoden1 ~]$ mount |grep asm
/dev/asm/acfsvol-23 on /cloudfs type acfs (rw)
/dev/asm/datastore-272 on /u01/app/oracle/oradata/datastore type acfs (rw)
/dev/asm/datastore-97 on /u02/app/oracle/oradata/datastore type acfs (rw)
/dev/asm/datastore-23 on /u01/app/oracle/fast_recovery_area/datastore type acfs (rw)

Step 5: Get the size of the volume /dev/asm/acfsvol-23

[grid@odanoden1 ~]$ /sbin/advmutil volinfo /dev/asm/acfsvol-23
Device: /dev/asm/acfsvol-23
Interface Version: 1
Size (MB): 204800
Resize Increment (MB): 64
Redundancy: high
Stripe Columns: 8
Stripe Width (KB): 1024
Disk Group: RECO
Volume: ACFSVOL
Compatible.advm: 12.1.0.2.0

Step 6: Resize the /cloudfs as follows. Here we are increasing /cloudfs by 50GB

[grid@odanoden1 ~]$ /sbin/acfsutil size +50g /cloudfs
acfsutil size: new file system size: 268435456000 (256000MB)

Step 7: Verify the new size of the volume /dev/asm/acfsvol-23

[grid@odanoden1 ~]$ /sbin/advmutil volinfo /dev/asm/acfsvol-23
Device: /dev/asm/acfsvol-23
Interface Version: 1
Size (MB): 256000
Resize Increment (MB): 64
Redundancy: high
Stripe Columns: 8
Stripe Width (KB): 1024
Disk Group: RECO
Volume: ACFSVOL
Compatible.advm: 12.1.0.2.0

Step 8: Verify the new size of /cloudfs file system

[grid@odanoden1 ~]$ df -h /cloudfs
Filesystem Size Used Avail Use% Mounted on
/dev/asm/acfsvol-23 250G 585M 250G 1% /cloudfs

Conclusion

In this article we have learned how to resize/increase the size of /cloudfs shared file system on ODA. The cloudfs file system is configured during the ODA deployment and it is set to 50GB which is not sufficient for storing the big files. The cloudfs is build using ACFS and it can be resized easily using ACFS commands.

Rename Oracle ASM Disk Group On Exadata

By Netsoftmate on

June 5, 2018

- Uncategorized

When Oracle ACS build Exadata Database Machine, they use the OEDA file that you sent them over for Exadata Install. The Exadata is built with default ASM Disk Group name DATAC1, RECOC1 & DBFS_DG. If you want to rename the DATAC1 and RECOC1 to something different to match your Organization standards you can do that by using the Oracle renamedg utility. The number Database version required to rename an ASM Disk Group is 11.2.

In this article we will demonstrate how to rename ASM Disk Group on Exadata Database Machine running Oracle Database 11.2

Here we want to change the following ASM Disk Group Names:
DATAC1 to DATA
RECOC1 to RECO

Steps to rename ASM Disk Group

Get the Database version

ORACLE_SID = [+ASM1] ? dbm011
The Oracle base remains unchanged with value /u01/app/oracle

Conclusion

In this article we have learned how to rename an ASM Disk group on Exadata running Oracle Database 11.2. Starting with Oracle Database 11.2 you can use the renamedg command to rename an ASM Disk Group. renamedg utility cannot rename the associated ASM/Grid disk disk name. Also renamedg cannot rename/update the control files, datafiles, redo log files and any other files that reference ASM DG for all databases. You must update database files manually after renaming ASM disk groups.

Create Cell Disk and Grid Disk Manually on Exadata

By Netsoftmate on

June 4, 2018

- Uncategorized

We had a failed hard disk on a Exadata Storage cell X6-2. So we scheduled the Oracle Field Engineer to replace the bad disk. Oracle Field Engineer came onsite and replaced the faulty hard disk. Post hard disk replacement we found that the physical disk and luns are created successfully but the Cell disk and Grid disks were not created automatically. When a hard disk is replaced, the lun, cell disk and grid disks are created automatically and grid disks are added to ASM disk group for you without any manual intervention. In some odd cases, the Cell disk and grid disks are not created automatically, in those cases you must manually create the Cell disk, create the Grid disks with proper sizes and add them to the ASM disk group.

In this article we will demonstrate how to create the Cell disk, Grid disks manually and add them to the respective ASM Disk Group.

Environment

Exadata X6-2 Elastic Configuration
4 Compute nodes and 6 Storage cells
Hard Disk Size: 8TB
3 ASM Disk Group: DATA, RECO & DBFS_DG
Total Number of Grid disks: DATA – 72, RECO – 72 & DBFS_DG – 60

Here the disk in the location 8:5 was back and replaced.

We can clearly see that the GRID DISKs are not present. So we have to create the GRID DISKs Manually.

Let’s try to create the Cell Disk

[root@dm01cel03 ~]# cellcli -e create celldisk CD_09_dm01cel03 lun=0_5

CELL-02526: Pre-existing cell disk: CD_09_dm01cel03

It says the Cell Disk already exists.

Let’s try to create the Grid Disk. To create the Grid Disk with proper size, get the Grid Disk size from a good Cell Disk as shown below.

[root@dm01cel03 ~]# cellcli -e list griddisk where celldisk=CD_07_dm01cel03 attributes name,size,offset

Now create the Grid Disk

[root@dm01cel03 ~]# cellcli -e create griddisk DATA_CD_05_dm01cel03 celldisk=CD_05_dm01cel03,size=5.6953125T

CELL-02701: Cannot create grid disk on cell disk CD_05_dm01cel03 because its status is not normal.

Looks like we can’t create the Grid Disk. We will now drop the Cell Disk and recreate it.

Conclusion

In this article we have learned how to create the Celldisk, Griddisks and add the newly created Griddisks to ASM Disk Group. When a hard disk is replaced, the lun, celldisk and griddisks are created automatically and griddisks are added to ASM disk group for you without any manual intervention. In some cases, if the Celldisk and grid disks are not created automatically, then you must manually create them and add them to the ASM disk group.

Multiplex Oracle Database Controlfile in ASM

Introduction:
In Oracle databases, it is recommended to multiplex you controlfile to safeguard against different failures like corruption, accidentally removing control file and so on.

In this article I will demonstrate how to multiplex/duplicating a controlfile into Automatic Storage Management (ASM).

Current Setup

Exadata 8-node RAC using ASM.
Current controlfile is stored in ASM.
Database is using SPFILE.
There are diffferent ASM Disk Groups available such as DATA, RECO, DBFS_DG, ACFS_DG.

dm01db01-orcldb1 {/home/oracle}:srvctl status database -d orcldb
Instance orcldb1 is running on node dm01db01
Instance orcldb2 is running on node dm01db02

Steps to multiplex controlfile in ASM When Database is using SPFILE

Update the control_files to include the location for second control file. The second controlfile is going to be created on different diskgroup RECO.

Configure ACFS on Exadata running Oracle 12.2.0.1 on Flex ASM Architecture

By Netsoftmate on

March 24, 2017

- Uncategorized

Overview

In one of previous article I have demonstrated how to configure ACFS on Exadata database running Oracle database 12.1.0.2 using standard ASM. Now I have an opportunity to configure Oracle GoldenGate on Exadata running Oracle database 12.2.0.1. So I have decides to configure ACFS on Exadata running Oracle database 12.2.0.1 using ASM Flex Architecture.

In this article I will demostrate how to configure Oracle ACFS on Exadata Database machine running Oracle Database 12.2.0.1 using Flex ASM.

For details on ACFS and how to configure ACFS on Standard ASM look at my previous article at:
http://netsoftmate.blogspot.in/2017/02/configure-acfs-on-exadata-database.html

Prerequisites

Verify ASM configuration on Standard Cluster (8 nodes)

Here the owner of the Grid Home is oracle user.

dm01db01-+ASM1 {/home/oracle}:id oracle
uid=1000(oracle) gid=1001(oinstall) groups=1001(oinstall),101(fuse),1002(dba),1003(oper),1004(asmdba)

Determine the ASM architecture

Here it is an ASM Flex configuration using the default cardinally=3 and the ASM instances are running on node 1, 2 and 4 out of 8 nodes:

dm01db01-+ASM1 {/home/oracle}:asmcmd showclustermode
ASM cluster : Flex mode enabled

dm01db01-orp258c1 {/home/oracle}:srvctl config asm -detail
ASM home: <CRS home>
Password file: +DBFS_DG/orapwASM
Backup of Password file:
ASM listener: LISTENER
ASM is enabled.
ASM is individually enabled on nodes:
ASM is individually disabled on nodes:
ASM instance count: 3
Cluster ASM listener: ASMNET1LSNR_ASM

dm01db01-+ASM1 {/home/oracle}:srvctl status asm
ASM is running on dm01db04,dm01db02,dm01db01
ASM is enabled.

Verify if ACFS/ADVM modules is enabled/loaded on every node in a standard cluster or every Hub Node in a Flex Cluster.

Step I – Create ASM Disk Group for ACFS

dm01db01-orcldb1 {/home/oracle}: id oracle
uid=1000(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba),1003(oper),1004(asmdba)

Set the ORACLE HOME and SID to ASM

dm01db01-orcldb1 {/home/oracle}:. oraenv
ORACLE_SID = [orcldb1] ? +ASM1
The Oracle base remains unchanged with value /u01/app/oracle

dm01db01-+ASM1 {/home/oracle}:env | grep ORA
ORACLE_SID=+ASM1
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/12.2.0.1/grid

Set DISPLAY

dm01db01-+ASM1 {/home/oracle}:export DISPLAY=10.30.20.13:0.0

Start asmca utility

dm01db01-+ASM1 {/home/oracle}:which asmca
/u01/app/12.1.0.2/grid/bin/asmca
dm01db01-+ASM1 {/home/oracle}:asmca

ASMCA warming up

if [ $? = “0” -o $? = “2” ]; then
   /u01/app/12.2.0.1/grid/bin/srvctl start filesystem -d /dev/asm/acfsvol-223
   if [ $? = “0” ]; then
      chown oracle:oinstall /acfs_ogg
      chmod 775 /acfs_ogg
      /u01/app/12.2.0.1/grid/bin/srvctl status filesystem -d /dev/asm/acfsvol-223
      exit 0
   else
      exit $?
   fi

Create ASM Disk Groups on Exadata Database Machine

By Netsoftmate on

March 23, 2017

- Uncategorized

Overview

Oracle ASM disk groups are built on a set of Exadata grid disks. Exadata uses ASM disk groups store database files.

ASM Provides 3 Types of Redundancy:

External: ASM doesn’t provide redundancy. External redundancy is not an option on Exadata. You must either use normal or high redundancy.

Normal: It provides two-way data mirroring. It maintains two copies of data blocks in separate failure groups

High: It provides three-way data mirroring. It maintains three copies of data blocks in separate failure groups

In this article I will demonstrate how to created ASM Disk Groups on Exadata database machine using ASMCA.

Environment

Exadata Database machine X2-2

8 Compute nodes, 14 Storage cells and 2 IB Switch

Steps to create ASM disk Group using ASMCA utility.

Set the environment variable to Grid Home and start asmca

dm01db01-orcldb1 {/home/oracle}:. oraenv

ORACLE_SID = [orcldb1] ? +ASM1

The Oracle base has been changed from /u01/app/oracle to /u01/app/grid

dm01db01-+ASM1 {/home/oracle}:which asmca

/u01/app/12.2.0.1/grid/bin/asmca

dm01db01-+ASM1 {/home/oracle}:asmca

1. Create ASM Disk Group using Normal Redundancy (3 failure groups)

First we will create an ASM disk group using Normal Redundancy using 3 storage cells.

ASMCA starting

Click on ASM Instances on left pane

Here we are running Flex ASM and current ASM instance is running on Nodes 1, 2 and 4

Click on Disk Groups. We can see currently there 2 disk groups one for OCR/Voting disks and another one for MGMT database repository. To create a new disk group click on “Create” button.

Click on “Change Disk Discovery Path”

Enter the following path to discover the grid disks.

Select desired grid disks to create ASM Disk Group.

Here I am creating DATA disk group by selecting DATA grid disks from 3 storage cells

Click on “Show Advanced Options” and select the ASM/Database/ADVM compatibility. Finally click Ok to create DATA disk group

DATA disk group creation in progress

We can now see that the DATA disk group is created

Let’s verify the newly created DATA disk group. Right click on the DATA disk group and select “view status details”

We can see that the DATA disk group is mounted on node 1, 2 and 4

2. Creaet ASM Disk Group Using High Redundancy (5 failure groups)

Now let’s create another ASM disk group using High Redundancy using grid disks from 5 storage cells.

Click Create button to create new ASM disk group

Enter the Disk Group name, select the desired grid disks and ASM/Database/ADVM attributes and click ok

DATA1 disk group creation is in process

We can see that DATA1 disk group created

3. Add disks to ASM Disk Group (add grid disks from one storage cell)

Now let’s Add disks to DATA1 disk group. I am going to add DATA grid disks from a storage to DATA1.

Right click on the DATA1 disk group and select Add Disks

Select the desired grid disks from storage cell and click ok

Disks are being added to DATA1

We can see the size of DATA1 disk group has increased

4. Drop disks from ASM Disk Group (remove grid disks from one storage cell)

This time let’s Drop disks from DATA1 disk group. I am going to remove DATA grid disks from a storage used by DATA1.

Right click on DATA1 disk group and select Drop Disks

Process started

Select the desired Grid disks to be dropped from DATA1 disk group and click ok

Disks are being dropped from DATA1

We can see that the DATA1 disk group size is dropped

Conclusion:

In this article we have learned different ASM disk group redundancy levels and how to create ASM disk group on Exadata using a set of Exadata grid disks. We have created different ASM disk group using different redundancy levels and performed few disk operations like adding and dropping.

Steps To Resize ASM disks in Exadata

Overview
In Exadata ASM disk groups are created from ASM disks which are provisioned as grid disks from Exadata storage cells. The grid disks are created from the celldisks. Normally, there is no free space in celldisks, as all space is used for grid disks, as shown below:

[root@dm01cel01 ~]# cellcli -e “list celldisk where name like ‘CD.*’ attributes name, size, freespace”
         CD_00_dm01cel01         528.734375G     0
         CD_01_dm01cel01         528.734375G     0
         CD_02_dm01cel01         557.859375G     0
         CD_03_dm01cel01         557.859375G     0
         CD_04_dm01cel01         557.859375G     0
         CD_05_dm01cel01         557.859375G     0
         CD_06_dm01cel01         557.859375G     0
         CD_07_dm01cel01         557.859375G     0
         CD_08_dm01cel01         557.859375G     0
         CD_09_dm01cel01         557.859375G     0
         CD_10_dm01cel01         557.859375G     0
         CD_11_dm01cel01         557.859375G     0

In this article I will demonstrate how to free up some space from the grid disks in RECO ASM disk group, and then reuse that space to increase the size of DATA disk group. The free space can be anywhere on the cell disks.

Environment

Exadata Full Rack X2-2
8 Compute nodes, 14 Storage cells and 3 IB Switches
High Performance Disks (600GB per disk)

1. Free up space on celldisks
Let’s say that we want to free up 50GB per disk in RECO disk group, we need to reduce the disk size in ASM, and then reduce the grid disk size in Exadata storage cells. Let’s do that for RECO disk group.

We start with the RECO grid disks with the size of 268.6875G:

[root@dm01cel01 ~]# cellcli -e “list grid disk where name like ‘RECO.*’ attributes name, size”
         RECO_dm01_CD_00_dm01cel01       105.6875G
         RECO_dm01_CD_01_dm01cel01       105.6875G
         RECO_dm01_CD_02_dm01cel01       105.6875G
         RECO_dm01_CD_03_dm01cel01       105.6875G
         RECO_dm01_CD_04_dm01cel01       105.6875G
         RECO_dm01_CD_05_dm01cel01       105.6875G
         RECO_dm01_CD_06_dm01cel01       105.6875G
         RECO_dm01_CD_07_dm01cel01       105.6875G
         RECO_dm01_CD_08_dm01cel01       105.6875G
         RECO_dm01_CD_09_dm01cel01       105.6875G
         RECO_dm01_CD_10_dm01cel01       105.6875G
         RECO_dm01_CD_11_dm01cel01       105.6875G

To free up 50 GB, the new grid disks size will be 105.6875 G – 50 GB = 55.6875 GB = 57024 MB.

2. Reduce size of RECO disks in ASM

5. Increase size of DATA disks in storage cells

We can now increase the size of DATA grid disks, and then increase all disks size of disk group DATA in ASM.

The current DATA grid disks size is 423 GB:

[root@dm01cel01 ~]# cellcli -e “list grid disk where name like ‘DATA.*’ attributes name, size”
         DATA_dm01_CD_00_dm01cel01       423G
         DATA_dm01_CD_01_dm01cel01       423G
         DATA_dm01_CD_02_dm01cel01       423G
         DATA_dm01_CD_03_dm01cel01       423G
         DATA_dm01_CD_04_dm01cel01       423G
         DATA_dm01_CD_05_dm01cel01       423G
         DATA_dm01_CD_06_dm01cel01       423G
         DATA_dm01_CD_07_dm01cel01       423G
         DATA_dm01_CD_08_dm01cel01       423G
         DATA_dm01_CD_09_dm01cel01       423G
         DATA_dm01_CD_10_dm01cel01       423G
         DATA_dm01_CD_11_dm01cel01       423G

The new grid disks size will be 423 GB + 50 GB = 473 GB.

Resize the DATA grid disks on all storage cells. On storage cell 1, the command would be:

8. Increase size of DATA disks in ASM

SQL> alter diskgroup DATA_dm01 resize all rebalance power 32;

Diskgroup altered.

Note that there was no need to specify the new disks size, as ASM will get that from the grid disks. The rebalance clause is optional.

The command will trigger the rebalance operation for disk group DATA.

Monitor the rebalance with the following command:

SQL> set lines 200
SQL> set pages 200
SQL> select * from gv$asm_operation;

no rows selected

Once the command returns “no rows selected”, the rebalance would have completed and all disks in disk group DATA should show new size:

SQL> select name, total_mb/1024 “GB” from v$asm_disk_stat where name like ‘DATA%’;

NAME                                   GB

Conclusion

In this article we have learned how to resize ASM disk in Exadata Database. If there is free space in Exadata cell disks, increasing the disk group size can be accomplished in two steps – grid disk size increase on all storage cells followed by the disk size increase in ASM. This requires a single ASM rebalance operation. If there is no free space in celldisks, some space may be freed up from other disk group. To reduce the size, first the ASM disk size is reduced and then reduced the grid disks size. To increase the size, first increase the grid disks size and the increase the ASM disk size.
