Part 1: Oracle 12c database reset

In this series of Blog posts I will share short videos demonstrating how storage data services can be used to perform many common data management and CDM (Copy Data Management) tasks using simply scripting, DevOPS automation tools and Pure Storage REST API’s .

Oracle 12c Database Reset

The video starts by refreshing an Oracle 12c database, and then simulates a typical development workflow process, where development databases are refreshed from production and then updated with:

  • New application configuration and setup
  • Additional synthetic and manufactured data supplement production data sets
  • Data masking and cleansing scripts.
  • Housekeeping routines e.g. clean-up workflow / staging tables

The video shows me taking a crash-consistent snapshot using a python script I have developed (available at using the Pure Storage REST API’s.

The video then proceeds to perform further updates and changes, before resetting the database back to the initial clone simulating an application test issue due to problems with the initial set-up and configuration.


Oracle dNFS Throughput testing

Oracle Direct NFS

In my previous Oracle dNFS Blog post I detailed how to configure Oracle 12cR2 to use Oracle dNFS multi-path, in this Blog I will share some test results that I achieved in my Oracle 12cR2 Pure Storage FlashBlade lab.

Oracle dNFS Flashblade configuration

Theoretical Limits

A Gigabit Ethernet network can transmit 1,000,000,000 bits per second, as we normally talk about X Bytes per second we need to divide this by 8 as there are 8 bits in a byte.

1GbE = (1,000,000,000 / 8) = 125,000,000 bytes/second

Unfortunately we can not use all 125,000,000 bytes/second to send data as we have multiple layers of overhead,  when using a default MTU of 1500 we can expect to experience ~6% overhead, this gives us:

1GbE= (1,000,000,000 / 8) less 6% overhead = 117,500,000 bytes/second

1 x  1GbE =   0.118GB/s
1 x 10GbE = 1.175GB/s
4 x 10GbE = 4.7GB/s
8 x 10GbE = 9.4GB/s  (2 Node RAC Cluster)

The dNFS Throughput Test

In the tests below I used Kevin Closson’s excellent SLOB with a custom configuration to produce Oracle FTS (Full Table Scans), many thanks to Frits Hoogland for sharing. This set-up allowed me to generate sufficient load to utilise the available bandwidth and see how close I can get to the ‘theoretical limits’.

Test 1 – Oracle 12cR2 dNFS disabled

OK, during this test we can see that Oracle EM Express is showing a single instance driving ~1.08GB/s IO Throughput

Oracle Express 12c
The Flashblade reporting throughput at ~1.09GB/s


Test 2 – Oracle 12cR2 dNFS enabled

For out next test, I have enabled dNFS with make -f dnfs_on but have not activated multipath, this was confirmed with the SQL below.

SELECT svrname, dirname, wtmax, rtmax FROM v$dnfs_servers;

-------        ------------------  ------ ------ /z-fbhosts_oradata   524288 524288 /z-fbhosts_orafra    524288 524288 /z-fbhosts_oraconfig 524288 524288

Oracle Express EM reports almost identical results with and without dNFS
And the Flashblade dashboard reports a similar result.

So lets enable multi-path and see the impact.

Test 3 – Oracle 12cR2 dNFS multi-path

So, lets install our oranfstab file and bounce the database and check again using the previous SQL script.

SELECT svrname, dirname, wtmax, rtmax FROM v$dnfs_servers; 
-------        ---------------- ------ ------ 
flashblade /z-fbhosts_oradata   524288 524288 
flashblade /z-fbhosts_orafra    524288 524288 
flashblade /z-fbhosts_oraconfig 524288 524288

We can see the Server Name has been picked up from the oranfstab rather than the mtab, we can also check that we are using multipath with the v$dnfs_channels view.

SELECT distinct svrname, path FROM v$dnfs_channels;
SVRNAME              PATH                                            
-------------------- -------------

Oracle EM Express is now showing we are using all 4 x 10GbE interfaces as expected and driving 4.03GB/s, also note the increase in Host CPU utilisation.

Ok, our final test will be to see if we get similar results with Oracle RAC

Test 4 – Oracle 12cR2 2 node RAC with dNFS multi-path

For this Oracle RAC test the slob.conf SQLNET_SERVICE_MAX parameter has been changed to 2 and to distribute the workload across the 2 nodes.

Oracle EM Express is showing that the workload has been evenly balanced across the 2 RAC nodes, achieving impressive throughput figures exceeding 8.3GB/s.

FB_RACThe Flashblade dashboard show that the 7 blades were able to deliver a consitent bandwidth of over 8.8GB/s for the Oracle workload utilising all 8 x 10GbE interfaces getting close to wire speed.

In my next Blog Post I plan to enable Jumbo Frames (JF) end-to-end and repeat the above tests.  With JF (MTU 9000) configured, I am hoping to see a ~5% improvement in bandwidth utilisation.

Using Oracle dNFS Multi-path

Oracle Direct NFS (dNFS) Multi-path

If you have multiple interfaces on your database server and your NFS server also supports multiple interfaces you should consider using Oracle dNFS multi-path.

Oracle dNFS multi-path removes the need to distribute and manage datafiles over multiple NFS mount points, Oracle dNFS multi-path can also improve throughput if you were not previously using all your available network interfaces and bandwidth.

In Oracle dNFS (Direct NFS) is disabled by default but can be easily enabled or disabled by following the steps below.

However, before we go through the Oracle dNFS configuration I will describe my lab set-up. My Database Server is configured with 4 x 10GbE all all on different sub-nets, and my  Pure Storage FlashBlade is configured with 4 NFS interfaces exporting 3 NFS mounts for Oracle data, Oracle FRA and shared configuration for my Oracle 12cR2 RAC cluster.

For further details see MOS Note: How to configure DNFS to use multiple IPs (Doc ID 1552831.1). It’s also possible to use the same subnet if required, checkout MOS Note: How to Setup Direct NFS client multipaths in same subnet (Doc ID 822481.1)


The oranfstab file

To use Oracle dNFS MultiPath you will need an oranfstab file, Oracle will look in the following order and locations for the configuration file.

  • /etc/oranfstab – Server wide
  • $ORACLE_HOME/dbs – Oracle Home specific

If no oranfstab file is found Oracle will use the /etc/mtab file to enable dNFS but you will have no MultiPath

Below is a copy of my $ORACLE_HOME/dbs/oranfstab

server: flashblade
local: path:
local: path:
local: path:
local: path:
nfs_version: nfsv3
export: /z-fbhosts_oradata  mount: /u01/oradata
export: /z-fbhosts_orafra   mount: /u01/app/oracle/fast_recovery_area
export: /z-fbhosts_oraconfig mount: /u01/shared_config

The parameters used in my oranfstab are described below:

The NFS server name, this can be anything and is used for information rather than any network lookups.

Up to four paths on the database host, specified by IP address or by name.

Up to four network paths to the NFS server, specified either by IP address, or by name.

The exported path from the NFS server.

The corresponding local mount point for the exported volume.

Specifies the NFS protocol version used by Direct NFS Client. Possible values are NFSv3, NFSv4, NFSv4.1, and pNFS. The default version is NFSv3. If you select NFSv4.x, then you must configure the value in oranfstab for nfs_version. Specify nfs_version as pNFS, if you want to use Direct NFS with Parallel NFS.

Enabling dNFS

Change dir to $ORACLE_HOME/rdbms/lib and use the make command e.g
 cd $ORACLE_HOME/rdbms/lib
  make -f dnfs_on

You should see something similar to this response:

rm -f /u01/app/oracle/product/; \
  cp /u01/app/oracle/product/ /u01/app/oracle/product/

Verify Oracle dNFS Usage

After applying changes restart the database and confirm your configuration change have had the desired impact.

The Oracle Alert file should now report the Oracle dNFS library is in use as it’s version.

Oracle instance running with ODM: Oracle Direct NFS ODM Library Version 4.0

We can also see that Oracle is using multiple paths e.g.

Direct NFS: channel id [0] path [] to filer [flashblade] via local [] is UP
Direct NFS: channel id [1] path [] to filer [flashblade] via local [] is UP
Direct NFS: channel id [2] path [] to filer [flashblade] via local [] is UP
Direct NFS: channel id [3] path [] to filer [flashblade] via local [] is UP

have had the desired impact by querying the v$dnfs_servers view.

Check to see if Enabled

SQL> SELECT svrname, dirname, nfsversion FROM v$dnfs_servers;

SVRNAME     DIRNAME                                     NFSVERSION
-------------------- -----------------------------------------------
flashblade     /z-fbhosts_oraconfig                       NFSv3.0
flashblade     /z-fbhosts_oradata                         NFSv3.0
flashblade     /z-fbhosts_orafra                          NFSv3.0

dNFS views

  • v$dnfs_stats          – shows dNFS performance statistics
  • v$dnfs_channels  – shows network channels is use by dNFS
  • v$dnfs_servers     – shows dNFS servers
  • v$dnfs_files           – shows files open for dNFS

Disabling dNFS

To disable dNFS change directory to $ORACLE_HOME/rdbms/lib and enter the following commands:

cd $ORACLE_HOME/rdbms/lib
  make -f dnfs_off

You should see something similar to this response:

rm -f /u01/app/oracle/product/

You can also now remove the previously created oranfstab file

Check to see if Disabled

SQL> SELECT svrname, dirname, nfsversion FROM v$dnfs_servers;
no rows selected

In my next post I will share some before and after test results.

Oracle Linux Container Registry

You may have read one of my previous posts Oracle 12c on Docker where I described  how you can get hold of official Oracle images from the Docker Store.

In this post I will share how you can now use the Oracle Container Registry to obtain Docker images for all licensable Oracle products.

To access the Oracle Registry Server you must have an Oracle Single Sign-On (SSO) account, this is the same account you use for and etc..

Navigate to and login using your SSO credentials, once authenticated you will be presented with the ‘Explore’ webpage.

You can then need to select the required Business Area e.g. ‘Database’ and click the red ‘Continue’ button, you will then be presented with the ‘Oracle Standard Terms and Restrictions’ agreement, review and if acceptable click ‘Accept’ and the bottom of the page.

You will then be returned to the ‘Explorer’ and notice that the Oracle Standard Terms and Restrictions shows you acceptance, this is valid for 8 hours only.


Note: you will not be able to pull and image until you have accepted Oracle Standard Terms and Restrictions.

You are now ready to pull the required image by clicking the repository  e.g. ‘enterprise’ and copying & pasting the provided pull command e.g.

The Repository Detail page provides set-up and usage information for the selected image.

Ok, now I have outlined the process let me walk you through it.

1) Login to Registry

ronsmac:~ ronekins$ docker login
Login Succeeded

2a) Pull Oracle Linux

Select ‘OS’ from the ‘Explore Official Business Areas’  and click the red ‘Continue’ button for oraclelinux. As before, accept Oracle Terms.


Now copy the docker pull command and paste in in your Mac or Linux shell.


ronsmac:~ ronekins$ docker pull
Using default tag: latest
latest: Pulling from os/oraclelinux
80d2e45a33d8: Pull complete
Digest: sha256:d31c2987a6c427eeca70fb28ccefd6e788e96b3202dc715aa3c80bcb23673f6d
Status: Downloaded newer image for

2b) Pull Oracle Database 12c Enterprise Edition


ronsmac:~ ronekins$ docker pull
Using default tag: latest
latest: Pulling from database/enterprise
cbb9821ba51c: Pull complete
9bd4d110366e: Pull complete
af8b29651e27: Pull complete

Status: Downloaded newer image for

3) Check Image size

Your Oracle two images are now available for use locally, you can check this with the docker image ls command. e.g.
ronsmac:~ ronekins$ docker image ls

REPOSITORY TAG IMAGE ID CREATED SIZE latest 6c33a25f4a29 5 weeks ago 229MB latest 12a359cd0528 2 months ago 3.44GB

Follow-up ‘Registry’ teaser

Within the ‘OS’ area Oracle provides a registry image which you can use to deploy a local registry so you can pull images and customise as required, the local registry also avoids the need the to authenticate every 8 hours, I will detail all of this in a follow-up post.

ronsmac:~ ronekins$ docker pull
Using default tag: latest
latest: Pulling from os/registry

ODC Appreciation Day: Online Database Move Datafile

ODC Appreciation Day – 10th October 2017

Last year Tim aka ‘ORACLE-BASE’ launched the the first OTN (Oracle Technology Network) Appreciation Day, after the success of last year this is being repeated again this year under the new moniker of ODC.

As today is Tuesday 10th October 2017 expect some great content from fellow Oracle ACE’s and Oracle community folk coming out throughout the day as the different timezones come online.

It’s my pleasure to contribute to this year’s ODC Appreciation Day (Oracle Developer Community) and my favourite reason feature is the Oracle 12c Online database move datafile feature.

This feature is great for fixing naming or directory structure errors, re-organising your database layout, adopting new standards or migrating between storage systems. It supports Oracle ASM and filesystems with the only restriction being you need to be on Oracle 12c, so upgrade it your still on Oracle 11gR2 and embrace online database move datafile.

You can read more about it at my Blog  Online Database Move Datafile

One-Click Oracle 12c Database Clone


Earlier in the year at the excellent OUgf Finnish Oracle User Group Harmony 17 conference, I performed a Live demo where I refreshed an Oracle 12c database using an Ansible Playbook in just over a minute, 1min 16sec to be more precise.


Once I had completed my presentation Frits Hoogland mentioned that he had recently used and Blogged on Ansible-Sempahore , an Open Source alternative to Ansible Tower which provides a Web UI and API’s for launching Ansible Tasks.

On my return to the UK I read Frits’ Blog – How to install semaphore UI for running Ansible and the installation instructions on the GitHub site, and was soon up and running.

Why this Blog

In this Blog post I am going to share how I used Ansible-Semaphore to launch my Ansible playbook to perform an Oracle 12c database refresh with a single click.

Once I had Semaphore installed, I configure the Inventory, Environment, Key Store and Playbook Repositories and added my Task Templates all through the Semaphore UI, all pretty straight forward, so no need to screenshot it.

semaphore Task Templates
semaphore Task Templates

A powerful feature of Semaphore is it’s integration with GitHub, this ensures every time a Playbook is run the last version is used as the code is pulled back from the repository.

Running my ‘Oracle Database Clone’ Ansible playbook is as now as simple as clicking ‘run!’ (no Playbook or Environment Overrides are required for this playbook)


At the end of each run semaphore provides a Task Log which is retained and accessible from the dashboard for historic review.


There we have it a One-Click Oracle 12c Database refresh in just under 1 minute 15 seconds.

If you want to see more, check out my YouTube channel to watch a demo of the above.

Oracle EBS R12.2.6 on Virtual Box Pt2

If you followed my previous post Oracle E-Business Suite R12.2.6 on Virtual Box you will have already downloaded the 19 required zip files, and be ready to go.

Ok, change directory to the location of the downloaded files, unzip and concatenate them into a single OVA file using the following:

$ unzip ‘V*.zip’

$ cat Oracle-E-Business-Suite-12.2.6_VISION_INSTALL.ova.* > Oracle-E-Business-Suite-12.2.6_VISION_INSTALL.ova

Getting started – Virtual Box

Start Virtual Box and navigate to File -> Import Appliance

Click on ‘Expert Mode’ and edit the ‘Virtual Disk Image’ path to a location with adequate space (~500GB), in this example I am using my Samsung Portable SSD T1 1TB dive mounted at ‘/Volumes/Samsung_T1’


Click ‘Import’, go to lunch or grab a coffee and watch the progress bar if you prefer, the remaining time will re-calulate periodically.


Once complete, start up your new Oracle EBS R12.2.6 VM from within Oracle VirtualBox

Oracle E-Business Suite R12.2.6


The initial boot will prompt you to change the ‘root’, ‘oracle’ and ‘applmgr’ passwords, the process will continue to start and configure an Oracle database called ‘EBSDB’.


Use ifconfig -a’ to determine your VM’s IP address from you VirtualBox console before using SSH from your host to connect using your preferred client.

Add the IP address to your local ‘/etc/host’ file so your browser can resolve your Oracle EBS VISION sandbox environment. e.g.

Docker, Oracle 12c and Persistent Storage


If you have read my previous posts on Docker you may have already installed Docker and have an Oracle 12c database running in a Docker container, if not you may want to read my first post on Docker – Running Oracle 12.2.01 on Docker

However, since I wrote the above post Oracle have published Docker images for many of their products, these can be found at the Docker Store. The Oracle images on the Docker Store are not just a great resource and help accelerate adoption, but are also certified and supported by Oracle.

Before continuing with this post you need to check-out my posts on using the new Oracle 12c Docker images and the Pure Storage Docker plugin as this post can be considered the ‘Return of the Jedi’  in the series.

Oracle 12c with Persistent Storage

In this post I will create a Docker container running an Oracle 12c database called PSTG using 4 mount points /u01, /u02, /u03 & /u04 mounted from a Pure Storage FlashArray.

Database environment Layout

/u01 – OraInventory and Oracle 12c product directories
/u02 – Oracle Datafile
/u03 – Fast Recovery Area
/u04 – RedoLog files.

The 4 mount points will all be using persistent All Flash Storage providing low latency performance, space efficient crash consistent snapshots and requiring no local storage.

First, confirm that you have installed the Oracle 12c image using the the following:

$ docker images list

docker_imagesYou should be able see the store/oracle/database-enterprise Docker Image, if missing you need to read my previous post.

Ok, copy the db_env.dat file created in the previous post to a new environment file $ORACLE_SID_env.dat and update database name and password e.g.

## Copyright(c) Oracle Corporation 1998,2016. All rights reserved.##
##                                                                ##
##                   Docker OL7 db12c dat file                    ##
##                                                                ##
## Specify the basic DB parameters
## db sid (name)
## default : ORCL
## cannot be longer than 8 characters
## db passwd
## default : Oracle
## db domain
## default : localdomain
## db bundle
## default : basic
## valid : basic / high / extreme 
## (high and extreme are only available for enterprise edition)
## end

We will now create the 4 volumes using the docker volume create command and Pure Storage Docker plug-in providing name, size and label.

 docker volume create --driver=pure --opt size=20GB --name=PSTG-u01 --label=product
 docker volume create --driver=pure --opt size=100GB --name=PSTG-u02 --label=oradata
 docker volume create --driver=pure --opt size=200GB --name=PSTG-u03 --label=fast_recovery_area
 docker volume create --driver=pure --opt size=10GB --name=PSTG-u04 --label=redo

We can use the docker volume ls command with a filter to list the 4 database volumes we are interested in using the following syntax

$ docker volume ls -f name=environment


The Pure Storage Docker Plugin also supports docker volume inspect, from here we can see the labels which we defined earlier, great way to see where and what the mount is being used for.

$ docker volume inspect volume name


Now that we have installed the Oracle 12c Docker image and created the 4 volumes we are ready to create our Oracle 12c container using the docker run command with -v to present our newly volumes to our container.

docker run -d –env-file ./PSTG_env.dat -p 1527:1521 -p 5507:5500 -it –name PSTG -v PSTG-u01:/u01 -v PSTG-u02:/u02 -v PSTG-u03:/u03 -v PSTG-u04:/u04 –shm-size=”8g” store/oracle/database-enterprise:

Progress can be monitored using the docker logs command.

docker logs -f PSTG

Once the container has started we can now connect to it and check out our Oracle 12c environment using the docker exec command and container name
