In the real world, organizations are complex organisms that have evolved over time, and have many important needs that must be met in order for them to flourish. Hence the need for Platform as a Service (PaaS) – cloud based tools that allow sophisticated organizations to move into the Cloud without having to sacrifice the needs of their workforce. Oracle partner IntraSee recently published a great video on their Usability First Methodology. We hope you'll check it out!

Oracle 12c – How to correct the error: “RMAN-20005: target database name is ambiguous”

Yann Neuhaus - Tue, 2017-02-21 08:09

I do have a Data Guard environment, where I have configured the RMAN DB_UNIQUE_NAME persistent setting for my primary and the standby. With the RMAN DB_UNIQUE_NAME settings I am able to run reports my Oracle Data Guard environment from any database. I could e.g. list all archivelogs for SITE1 from SITE2 or the other ways around.
Or I could show all persistent settings for SITE1 from SITE2 and of course the other way around. The only prerequisite for this feature is the RMAN catalog. In case you are not connected to the RMAN catalog you end up with the following error:


using target database control file instead of recovery catalog
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-05037: FOR DB_UNIQUE_NAME option cannot be used in nocatalog mode

After connecting to the catalog, you can use this feature, e.g. to show the archive deletion policy.

$ rman target sys/welcome1 catalog /@rcat

connected to target database: DBIT121 (DBID=644484523)
connected to recovery catalog database

RMAN configuration parameters for database with db_unique_name DBIT121_SITE1 are:

RMAN configuration parameters for database with db_unique_name DBIT121_SITE2 are:

There are quite a lot options which can be combined with the DB_UNIQUE_NAME feature like the following.


But getting back to my issue. I was running a resync catalog from my Standby database and ended up with the following error:


resyncing from database with DB_UNIQUE_NAME DBIT121_SITE1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-20005: target database name is ambiguous

RMAN says that the target database name is ambiguous. But what does this mean. Let’s take a look a the RMAN error with the oerr utility. The oerr utility can not only be used with “ORA” error codes like “oerr ora 01555″, but also with “RMAN” error codes.

$ oerr rman 20005
20005, 1, "target database name is ambiguous"
// *Cause: two or more databases in the recovery catalog match this name
// *Action:

Ok. This error is much more precise. Looks like that RMAN found more the one database called DBIT121 in the catalog, and so RMAN does not know, on which DBID to perform the requested command. Ok. So let’s connect to the RMAN catalog and check if this is really the case.

        FROM DB, DBINC
         AND DBINC.DB_NAME   = 'DBIT121' ;  2    3    4

---------- ---------- -------------- --------
         1  642589239              2 DBIT121
    546780  644484523         546781 DBIT121

Indeed. I do have two different DBID’s pointing to the same DB_NAME. Kinda confusing for RMAN. But which one is the one that have been backed up. We could query the RC_BACKUP_SET and RC_BACKUP_PIECE views to find that out.

         , RD.NAME
         , RBS.DB_ID

After checking the output, I see that DBID 644484523 is the correct one, and DBID 642589239 is the one I want to get rid of.

To do so, we can shutdown the Standby database and start it up with nomount. The reason for that, is that you can’t issue the SET DBID command against a database which is mounted or open.

RMAN> SET DBID=642589239;

executing command: SET DBID
RMAN-00571: ===========================================================

RMAN-03002: failure of set command at 02/21/2017 13:15:26
RMAN-06188: cannot use command when connected to a mounted target database

Ok. Let’s go the nomount and execute the “unregister database;” command after the correct DBID is set.

$ rman target sys/welcome1 catalog /@rcat

database name is "DBIT121" and DBID is 642589239

RMAN> unregister database;

database name is "DBIT121" and DBID is 642589239

Do you really want to unregister the database (enter YES or NO)? YES
database unregistered from the recovery catalog


Let’s check the RMAN catalog again.

        FROM DB, DBINC
         AND DBINC.DB_NAME   = 'DBIT121' ;  2    3    4

---------- ---------- -------------- --------
    556718  644484523         556719 DBIT121

Cool. Looks much better. :-) Now my resync catalog from SITE1 issued from SITE2 works again.


List of Databases
DB Key  DB Name  DB ID            Database Role    Db_unique_name
------- ------- ----------------- ---------------  ------------------
556718  DBIT121  644484523        PRIMARY          DBIT121_SITE1
556718  DBIT121  644484523        STANDBY          DBIT121_SITE2


resyncing from database with DB_UNIQUE_NAME DBIT121_SITE1
starting full resync of recovery catalog
full resync complete

The RMAN DB_UNIQUE_NAME persistent setting is a quite cool feature. This is something I would really recommend when working with RMAN and Data Guard. It allows you to do actions on primary from the standby or the standby from the primary. It doesn’t matter. But take care that you don’t have multiple DBID’s pointing to the same DB in your RMAN catalog.

Configuring Django with Apache on a Raspberry Pi

The Anti-Kyte - Tue, 2017-02-21 07:07

Deb has another job for me to do around the house.
She would like to have a means of looking up which Films/TV Series we have lying around on Blu-Ray or DVD so she can save time looking for films we haven’t actually got. Just to be clear, she doesn’t mind hunting around for the disc in question, she just wants to make sure that it’s somewhere to be found in the first place.
She wants to be able to do this on any device at any time (let’s face it, there’s even a browser on your telly these days).
As DIY jobs go, this is a long way from being the worst as far as I’m concerned. After all, this time I should be able to put something together without the potential for carnage that’s usually attendant when I reach for the toolbox.

I happen to have a Raspberry Pi lying around which should serve as the perfect hardware platform for this sort of low traffic, low data-volume application.
The Pi is running Raspbian Jessie.
Therefore, Python is the obvious choice of programming language to use. By extension therefore, Django appears to be a rather appropriate framework.
In order to store the details of each movie we have, we’ll need a database. Django uses with Sqlite as the default.

We’ll also need an HTTP server. Whilst Django has it’s own built-in “development” server for playing around with, the favoured production http server appears to be Apache.

Now, getting Django and Apache to talk to each other seems to get a bit fiddly in places so what follows is a description of the steps I took to get this working…leaving out all the bits where I hammered my thumb…

Other places you may want to look

There are lots of good resources for Django out there.
The Django Project has a a list of Django Tutorials.
One particularly good beginners tutorial, especially if you have little or no experience of programming, is the Django Girls Tutorial.

Making sure that Raspbian is up-to-date

Before we start installing the bits we need, it’s probably a good idea to make sure that the OS on the Pi is up-to-date.
Therefore, open a Terminal Window on the Pi and run the following two commands…

sudo apt-get update -y
sudo apt-get upgrade -y

This may take a while, depending on how up-to-date your system is.
Once these commands have completed, you’ll probably want to make sure you haven’t got any unwanted packages lying around. To achieve this, simply run :

sudo apt-get autoremove
Python Virtual Environments

Look, don’t panic. This isn’t the sort of Virtual Environment that requires hypervisors and Virtual Machines and all that other complicated gubbins. We’re running on a Pi, after all, we really haven’t got the system resources to expend on that sort of nonsense.
A Python virtual environment is simply a way of “insulating” your application’s Python dependencies from those of any other applications you have/are/will/may develop/run on the same physical machine.

Getting this up and running is fairly simple, but first, just as a sanity check, let’s make sure that we have Python 3 installed and available :

python3 --version


Provided all is well, then next step is to install the appropriate Python 3 package for creating and running Virtual Environments so…

sudo pip3 install virtualenv

Next, we need to create a parent directory for our application. I’m going to create this under the home directory of the pi user that I’m connected as on the pi.
I’m going to call this directory “dvds” because I want to keep the name nice and short.
To create a directory under your home in Linux…

mkdir ~/dvds

You can confirm that the directory has been created in the expected location by running …

ls -ld ~/dvds

drwxr-xr-x 5 pi pi 4096 Feb 14 13:05 /home/pi/dvds


cd ~/dvds
virtualenv dvdsenv

…will create the python executables referenced in this environment :


Notice that this has created a directory structure under a new directory called dvdsenv :


Now start the virtualenv and note what happens to the prompt :

source dvdsenv/bin/activate


One small but welcome advantage to running in your new environment is that you don’t have to remember the “3” whenever you want to run python. The easiest way to demonstrate this is to stop the virtual environment, get the python version, then re-start the virtual environment and check again, like this…


Installing Django

We want to do this in our newly created virtual environment.
So, if you’re not already in it, start it up :

cd ~/dvds
source dvdsenv/bin/activate

Now we use pip3 to get django. NOTE – as with the python command, we don’t need to remember the “3” for pip inside the virtual environment…

pip install django


Still in the Virtual environment, we can now create our new django project ( be sure to be in the dvds directory we created earlier) :

cd ~/dvds
django-admin.py startproject dvds .

Note the “.” at the end of this command. that means that the directory tree structure of the new application should be created in the current directory.

Once this has run, you should see a sub-directory called dvds :


We now need to make some changes to some of the files that Django has created in this directory. To make these changes I’m going to use the default Raspbian graphical editor, Leafpad. If you’d prefer something like nano, then knock yourself out. Just replace “leafpad” with the executable name of your editor in the commands that follow…

leafpad ~/dvds/dvds/settings.py

We need to make a couple of changes to this file.
Firstly, in the INSTALLED_APPS section of the file (around about line 33) we want to add our application – dvds. After the change, this particular section of the file should look something like this :


The other thing to do is to make sure that STATIC_ROOT has been defined. If this does not already exist in settings.py then add it at the end of the file :

STATIC_ROOT = os.path.join( BASE_DIR, "static/")

To get Django to accept these changes we need to migrate them. Note that we need to do this from inside the virtual environment so start it if it’s not already running…

cd ~/dvds
source dvdsenv/bin/activate
./manage.py makemigrations
./manage.py migrate


Before we finally get Django up and running, we need to setup the default admin UI.
To do this, we first need to create an admin user :

./manage.py createsuperuser


…then setup the static files used by the admin app…

./manage.py collectstatic

You have requested to collect static files at the destination
location as specified in your settings:


This will overwrite existing files!
Are you sure you want to do this?

Type 'yes' to continue, or 'no' to cancel:

Type “yes” and you’ll get …

Copying '/home/pi/dvds/dvdsenv/lib/python3.4/site-packages/django/contrib/admin/static/admin/css/base.css'
Copying '/home/pi/dvds/dvdsenv/lib/python3.4/site-packages/django/contrib/admin/static/admin/css/widgets.css'
Copying '/home/pi/dvds/dvdsenv/lib/python3.4/site-packages/django/contrib/admin/static/admin/css/rtl.css'
Copying '/home/pi/dvds/dvdsenv/lib/python3.4/site-packages/django/contrib/admin/static/admin/js/admin/RelatedObjectLookups.js'

61 static files copied to '/home/pi/dvds/static'.

Now we can test that everything is working as expected by running Django’s own “development” http server :

./manage.py runserver


If we now point the Epiphany browser on the pi to that address, we should see the default Django page :


Better even than that, if you append “/admin” to the url – i.e.

You should see…


Using the username and password you just created for with the “createsuperuser” command just now, you should get access to :


Installing Apache

This is fairly straight forward, to start with at least.
First of all, you don’t need to be in the Python Virtual Environment for this so, if you are then deactivate it :


Once this command has completed, the prompt should now return to normal.

I’ll be sure to tell you when you need the Virtual Environment again.

To install Apache…

sudo apt-get install apache2 -y

Once that’s completed, you should be able to confirm that Apache is up and running simply by pointing your browser to :


…which should display the Apache Default Page :


In addition to Apache itself, we need some further packages to persuade Apache to serve pages from our Django application :

sudo apt-get install apache2-dev -y
sudo apt-get install apache2-mpm-worker -y
sudo apt-get install libapache2-mod-wsgi-py3 

Got all that ? Right…

Configuring Apache to serve Django Pages using WSGI

First of all, we need to tell Apache about our Django application. To do this we need to edit the 000-default.conf which can be found in the Apache directories :

leafpad /etc/apache2/sites-available/000-default.conf

We need to add some entries to the section of the file. Once we’re done, the entire file should look something like this :

<VirtualHost *:80>
	# The ServerName directive sets the request scheme, hostname and port that
	# the server uses to identify itself. This is used when creating
	# redirection URLs. In the context of virtual hosts, the ServerName
	# specifies what hostname must appear in the request's Host: header to
	# match this virtual host. For the default virtual host (this file) this
	# value is not decisive as it is used as a last resort host regardless.
	# However, you must set it for any further virtual host explicitly.
	#ServerName www.example.com

	ServerAdmin webmaster@localhost
	DocumentRoot /var/www/html

	# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
	# error, crit, alert, emerg.
	# It is also possible to configure the loglevel for particular
	# modules, e.g.
	#LogLevel info ssl:warn

	ErrorLog ${APACHE_LOG_DIR}/error.log
	CustomLog ${APACHE_LOG_DIR}/access.log combined

	# For most configuration files from conf-available/, which are
	# enabled or disabled at a global level, it is possible to
	# include a line for only one particular virtual host. For example the
	# following line enables the CGI configuration for this host only
	# after it has been globally disabled with "a2disconf".
	#Include conf-available/serve-cgi-bin.conf

 Alias /static /home/pi/dvds/static
    <Directory /home/pi/dvds/static> 
        Require all granted

    <Directory /home/pi/dvds/dvds>
        <Files wsgi.py>
            Require all granted

    WSGIDaemonProcess dvds python-path=/home/pi/dvds python-home=/home/pi/dvds/dvdsenv
    WSGIProcessGroup dvds
    WSGIScriptAlias / /home/pi/dvds/dvds/wsgi.py

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Next, we need to make sure that Apache has access to the bits of Django it needs. To do this, we’ll give access to the group that the user under which Apache runs belongs to :

chmod g+w ~/dvds/db.sqlite3
chmod g+w ~/dvds
sudo chown :www-data db.sqlite3
sudo chown :www-data ~/dvds

After all of that, the “Apache” group (www-data) should be the group owner of the Virtual environment as well as our SQLITE database :


Finally, we need to re-start Apache for these changes to take effect :

sudo service apache2 restart

If we now go to the Apache url (http://localhost), we can see that it’s now showing the Django default page :

If you see that then, congratulations, it works !

Accessing Django from another computer on the network

The server name of my Raspberry Pi is raspberrypi. If you want to check that this is the case for you, simply open a Terminal on the pi and run :

uname -n

In order to access the application from other computers on my local network, I’ll need to add this server name to the ALLOWED_HOSTS list in the settings.py file of the application.

To do this :

leafpad ~/dvds/dvds/settings.py

Amend the ALLOWED_HOSTS entry from this :


…to this…


And you should now be able to access the Django application from a remote machine by using the url :


…like this…


Hopefully, this has all helped you to get up and running without hitting your thumb.

AMIS Tools Showroom – The Sequel – Donderdag 16 maart 2017

Amis Blog - Mon, 2017-02-20 23:25

Donderdag 16 maart

17.00-21.00 uur

AMIS, Nieuwegein

Aanmelden via: bu.om@amis.nl

Op donderdag 16 maart vindt de tweede AMIS Tools Showroom Sessie plaats. De eerste sessie was op 13 december: hierin hebben 16 AMIS-ers in korte en hele korte presentaties en demonstraties allerlei handige tools en hulpmiddelen laten zien. De nadruk in deze sessie lag op tools voor monitoring, communicatie en collaboration.

In deze tweede sessie gaan we op zoek naar nog een collectie tools. Deze uitnodiging betreft dan ook twee aspecten:

· Wil je er op 16 maart bij zijn om tools door je vakbroeders gepresenteerd te krijgen?

· Heb jij een tool waarover je tijdens deze sessie wil presenteren? Denk bijvoorbeeld aan tools rondom web conferencing & video streaming, screen cams, text editing, chat, image editing, data visualisatie, document sharing, voice recognition. En andere tools, apps en plugins die jij handig vindt in je werk en die je aan je vakgenoten zou willen laten zien – in een korte presentatie (5-15 min) – liefst met een demo.

Zou je via het volgende formulier willen aangeven welke tools voor jou interessant zijn en over welk tool jij wel zou willen presenteren: https://docs.google.com/forms/d/e/1FAIpQLSdNPwUACXxWaZGfs911UraVFQp5aWqeJVEx0xrSRFQTcYnYXA/viewform .
Op basis van de resultaten van deze survey kunnen we de agenda samenstellen voor deze sessie.
