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: Resize CloudFS ACFS File System Manually

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.

Oracle Database Appliance – Resize ACFS File System

By Netsoftmate on

September 15, 2017

Introduction

Oracle Database Appliance uses the Oracle Automatic Storage Management Cluster File System (Oracle ACFS) for database and virtual machine files storage. Oracle ACFS provides both servers with concurrent access to some or all of the shared storage on Oracle Database Appliance. It supports space-efficient storage snapshots, which provides fast provisioning databases and virtual machines within Oracle Database Appliance.

To check Storage used for database running on ODA, execute the following:

[root@dzuro614001nor ~]# oakcli show databases
Name Type Storage HomeName HomeLocation Version
—– —— ——– ————– —————- ———-
odatest RAC ACFS OraDb12102_home1 /u01/app/oracle/product/12.1.0.2/dbhome_1 2.1.0.2.170117(24732082,24828633)

In this article I will demonstrate how to check ACFS mounts on ODA and how to resize an Oracle ACFS file system.

[root@odanode1 ~]# su – grid

[grid@odanode1 ~]$ . oraenv
ORACLE_SID = [+ASM1] ? +ASM2
The Oracle base has been set to /u01/app/grid

[grid@odanode1 ~]$ mount | grep asm

Exadata: Install Oracle GoldenGate 12c using ACFS File System

By Netsoftmate on

March 27, 2017

- Uncategorized

Overview
You can install Oracle GoldenGate for Oracle RAC using:

Shared Storage

NFS, OCFS2, DBFS, OCFS

Local file system

You can Install Oracle GoldenGate 12c in 2 ways:

Graphical User Interface (GUI)
Using response file (Silent)

In this article I will demonstrate how to Install Oracle GoldenGate 12c using GUI on a full Rack Exadata Database Machine using ACFS file system.

What is ACFS?
Automatic Storage Management Cluster File System (ACFS) was introduced in Oracle database 11gR2. ACFS is a general purpose single-node or cluster file system on top of ASM. ACFS can be accessed using industry-standard Network Attached Storage (NAS) file access protocols: Network File System (NFS) and Common Internet File System (CIFS)

Installing GoldenGate on ACFS
ACFS file systems are mounted on all nodes in a cluster. Oracle GoldenGate is supported in an Oracle ACFS environment. GoldenGate should be installed in the cluster to capture the data from the database.

How to configure ACFS?
Take a look at the below 2 articles on how to configure ACFS on Exadata Database Machine.

Flex ASM: http://netsoftmate.blogspot.in/2017/03/configure-acfs-on-exadata-running.html
Standard ASM: http://netsoftmate.blogspot.in/2017/02/configure-acfs-on-exadata-database.html

Environment:

Exadata Database Machine X5-2 Full Rack
Oracle GoldenGate 12.2.0.1
Oracle Database 12.2.0.1
ASM Cluster File System (ACFS)

Verify ACFS is running and mounted

Conclusion
This completes our Oracle GoldenGate 12c installation on Exadata database machine using ACFS. We have seen how much easy it is to install Oracle GoldenGate software using GUI interface. The key for installing Oracle GoldenGate on 12c a RAC environment is to choose a shared location for software. You can also choose to install Oracle GoldenGate on local file system if you don’t have a shared location.

Configure ACFS on Exadata Database Machine

About ACFS:

ACFS stands for Oracle Automatic Storage Management Cluster File System
ACFS extends ASM functionality to support all kind of files like database files, application files and general purpose files.
Oracle ACFS is a High Availability Cluster File system and it is tightly coupled with Oracle Clusterware technology.
It can manage large number of file systems and files.
One can manage ACFS/ADVM using: ASMCA, ASMCMD, SQL*PLUS, OEM and ACFS Plug-ins

In this article I will demostrate how to configure Oracle ACFS on Exadata Database machine. Before start with the actual configuration, let’s discuss the few important points about ACFS and configure it on Exadata.

Oracle Automatic Storage Management Cluster File System (ACFS) on Exadata Database Machine:

Starting with Oracle Grid Infrastructure version 12.1.0.2, Oracle ACFS supports all database files and general purpose files on Oracle Exadata Database Machine running Oracle Linux on database servers.

The following database versions are supported by Oracle ACFS on Exadata Database Machine:

Oracle Database 10g Rel. 2 (10.2.0.4 and 10.2.0.5)
Oracle Database 11g (11.2.0.4 and higher)
Oracle Database 12c (12.1.0.1 and higher)

Some important information about using Oracle ACFS with Exadata

Oracle ACFS supports all database file types and general purpose files
All Oracle ACFS advanced functionality is supported on Exadata including:

Snapshots, replication, tagging, security, encryption, audit and HANFS.

Patches required

Please refer to the MOS note for important fixed required for Oracle ACFS on Exadata Database Machine.

2022172.1

Oracle ACFS restriction

Smart Scan, Storage Indexes, IO Resource Manager (IORM) are currently not supported.
Smart FC read operation are cached.
Smart FC write operations is not supported
Smart Flash Logging is not supported.
HCC is supported with fix for bug 19136936
Hardware Assisted Resilient Data (HARD) checks are not performed.
Oracle ACFS replication or security/encryption/audit is only supported with general purpose files.
Database files in ACFS doesn’t support replication or security/encryption/audit

Performance Optimization

When storing database data files on Oracle ACFS, Initialization parameter FILESYSTEMIO_OPTIONS must be set to ‘setall’. Other settings are not supported.
For each disk group that contains an Oracle ADVM volume that is intended to hold data files, set ASM and ADVM compatibility attributes to 12.1 or higher as this will ensure optimized performance.

Uses of ACFS on Exadata Database Machine

Since Oracle ACFS support database version 10.2.0.4 and 10.2.0.5, Customers can migrate their 10g database to Exadata. Later they upgrade their 10g database to 11g or higher database version.
Oracle ACFS can be used as a shared Oracle Home for RDBMS, Middleware, GoldenGate binaries.
Oracle ACFS can be used to store Oracle GoldenGate related files such as trail file, checkpoint files, parameter files and so on.

Steps to configure ACFS

It consists of 4 steps:

Load ACFS/ADVM module on all the nodes
Create ASM diskgroup for ACFS
Create ASM Volume
Create ASM Cluster File system

Current Environment Details:

Exadata Database Machine X5-2 Full Rack
Exadata Storage Software version 12.1.2.1.1
Oracle Grid/Database Version 12.1.0.2

I – Load ACFS/ADVM module on all the nodes

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/12.1.0.2/grid

Set DISPLAY

dm01db01-+ASM1 {/home/oracle}:export DISPLAY=10.30.201.137:0.0

Start asmca utility

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

Make sure ACFS/ADVM modules loaded on every node in a standard cluster.

Here ACFS/ADVM module is not load on node 1.
Execute the following command to load acfs module.

[root@dm01db01 ~]# /u01/app/12.1.0.2/grid/bin/acfsload -h
ACFS-9228: usage: acfsload [-h] {start|stop} [-s]

[root@dm01db01 ~]# /u01/app/12.1.0.2/grid/bin/acfsload start

Refresh or Exit and start ASMCA again.

I still see that ACFS/ADVM is “Not Installed” on node 1 though we have enabled/loaded it manually on node 1 and verified. Let’s move on and see if it is just a BUG. If there is no issue we should be able to configure ASM Volume and ACFS without any issues.

II – Create ASM diskgroup for ACFS

On Disk Groups page click on “Create”

On Create Disk Group page, specify:

Disk Group Name: ACFS_DG
Redundancy: Normal
Select Member Disk: Show Eligible
