European Moodle 2.7 Hosting - HostForLIFE.eu :: What’s new in Moodle 2.7 ? Let’s Find out and Try With Us!

clock July 16, 2014 07:04 by author Peter

Moodle 2.7 has been released. The upgrade to the free and open source learning management system includes new themes with improved responsive design, a new accessibility-focused text editor and more. These are just the minimum supported versions. In addition to a number of bug fixes and small improvements, security vulnerabilities have been discovered and fixed.  We highly recommend that you upgrade your sites as soon as possible. Upgrading should be very straightforward. As per our usual policy, admins of all registered Moodle sites will be notified of security issue details directly via email and we'll publish details more widely in a week.

Moodle 2.7 brings a few headline feature improvements, including the replacement of the TinyMCE editor with ‘Atto’ and the continued emphasis on responsive design with ‘Clean’ the default theme and the new ‘More’ theme being released. Compared to a number of earlier Moodle releases though, some might question whether there is a compelling reason to upgrade to Moodle 2.7 (especially if you have only recently upgraded to Moodle 2.6).

And here’s Top new features of Moodle 2.7:

Clean and Responsive Design
Moodle 2.7 has two core themes; Clean and More.  Clean is the responsive bootstrap based theme which has now been made the default theme.  More is a completely new, customisable theme, created for the novice user or administrators who are unable to access theme files on the server.

New Text Editor, Atto
 In the latest release of Moodle, they have named the text editor ‘Atto’, the new Atto feature allows tighter integration with Moodle meaning there are enhancements to usability and accessibility like never before.

Mobile Notifications. This is possibly the most exciting new feature to enable ‘push’ learning to users on the go. The essential tool for Learning and Development professions in marketing the platform, this new feature will allow you to push notifications about new learning modules created within Moodle which your learners can take advantage of on the go.

Improved quiz reports and other general improvements to quizzes and question banks, such as the ability to duplicate a question with a single click, the ability to require an attachment for essay questions and the ability to save changes and continue editing;

Improved Scheduling System. Administrators can now schedule, more precisely routine tasks, by specifying the minute/hour/day or month the task is to be run.

First long term support release: 3 years until May 2017 for security and data loss bug fixes .

Easily create and manage Quiz & Question bank. As well as an updated question type selector, duplicating and moving questions is now easier, and there is an option to 'Save changes and continue editing'.

Install the new Moodle software manually

1. First, Move your old Moodle software program files to another location. Do NOT copy new files over the old files.
2. Then, Unzip or unpack the upgrade file so that all the new Moodle software program files are in the location the old files used to be in on the server. Moodle will adjust SQL and moodledata if it needs to in the upgrade.Copy your old config.php file back to the new Moodle directory.
3. As mentioned above, if you had installed any plugins on your site you should add them to the new code tree now. It is important to check that you get the correct version for your new version of Moodle. Be particularly careful that you do not overwrite any code in the new version of Moodle.
4. Do not forget to copy over your moodledata folder / directory. If you don't you will get a "fatal error $cfg- dataroot is not configured properly".

European Windows Cloud Hosting Service :: Why Migrate Your Site to Cloud Hosting? What is the Benefits Using Cloud Hosting?

clock July 14, 2014 11:45 by author Scott

In this article, I’ll introduce you to the cloud, help you interpret the buzzwords, and explain how your business might save time and money using a cloud hosting service.

Cloud computing is a general term for anything that involves delivering hosted services over the Internet. One can also say that Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand. These hosted services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams.

 

A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access).

Who Use Cloud Computing?

There are many hosting provider use Cloud providers now, like Yahoo, Amazon, Google, and IBM. We as Microsoft hosting partner also update our technology and we also offering Windows Cloud Dedicated Server from affordable price.

Why many hosting provider choose Cloud?

Here are several reasons why many hosting provider switch to cloud service:

1. Data protection

Data is key and possibly the most important asset for organisations - a single breach or leak of sensitive data can cripple the entire business, so a data protection strategy must protect the data itself. The ability to move sensitive information into and throughout the cloud is essential for businesses to function and collaborate efficiently, quickly and freely - but this ability must be supported by a comprehensive data protection strategy. The trick is to protect data at the moment of creation, before it moves out of the enterprise or even enters the cloud. Only by doing that can you ensure that any data source is comprehensively protected, and the risk to potential exposure is minimised.

2. Scalability and flexibility

The cloud has opened up previously unseen opportunities for organisations to grow and expand quickly, smoothly and with ease. With information immediately available wherever you are, the cloud offers the flexibility and scalability that in the past was an insurmountable obstacle for businesses restricted by their on-site resources. The key to successfully harnessing this opportunity is a flexible data security architecture that is adaptable across multiple applications and systems, while not adversely impacting the user experience. Failure to put a comprehensive, data-centric protection program can cause cloud initiatives to be delayed or fraught with hidden security issues.

3. Cost efficiencies

This element is two-fold. First, reap the powerful cost savings by only paying for what you use. The second element is that most cloud computing platforms provide the means to capture, monitor, and control usage information for accurate billing. A single, comprehensive data protection platform can eliminate the threat of risky fines from compliance breaches or data loss, while also reducing the need to invest into multiple security tools.

European SQL 2014 Hosting - France :: How to Fix The model of the processor on the system does not support creating filegroups with MEMORY_OPTIMIZED_DATA in In-Memory OLTP SQL 2014

clock July 4, 2014 08:45 by author Scott

Microsoft's new release of SQL Server 2014 comes pretty close on the heels of the last SQL Server 2012 release. In this article I will be exploring and explaining about In Memory OLTP with SQL Server 2014.

SQL Server 2014 CTP is available for download and evaluation and it contains a couple of exciting performance enhancements. One of these is OLTP databases optimized to be memory resident.

This is 2 concern that I want to check:

1. Because SQL 2014 is only at CTP1 compatibility with earlier versions is not guaranteed and therefore Microsoft won’t let you install this side by side with any other versions.

2. Because of gotcha number one you’ll probably decide,  for example you install it in a virtual machine. Using Oracle Virtual Box you might strike this error when you try to create a memory optimised filegroup:

Msg 41342, Level 15, State 1, Line 5

The model of the processor on the system does not support creating filegroups with MEMORY_OPTIMIZED_DATA. This error typically occurs with older processors. See SQL Server Books Online for information on supported models.

To resolve this – navigate to the virtual box install folder and run this command:

VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1

I had to restart the guest and the host for this change to stick.

DDL.

Now with that all working time to create the database.

CREATE DATABASE InMemDB
GO

Add a filegroup for the in memory objects (alter the path for your instance).

ALTER DATABASE InMemDB ADD FILEGROUP InMemDB_mod CONTAINS MEMORY_OPTIMIZED_DATA
ALTER DATABASE InMemDB ADD FILE (name='InMemDB_mod1', filename='E:\SQLData\InMemDB_mod1') TO FILEGROUP InMemDB_mod
GO

A database can contain a mix of in memory tables (and the new natively compiled stored procedures) and traditional disk based tables. The in memory tables are marked with the keywords MEMORY_OPTIMIZED=ON and they must have at least one hash index – it is not possible to create a heap.

USE InMemDB
GO

CREATE TABLE dbo.Table1 (
   Id_tb1 int not null primary key nonclustered hash with (bucket_count=20480),

   Int_Val int not null index ix_Int_Val nonclustered hash with (bucket_count=10240),
   CreateDate datetime2 not null,
   [Description] varchar(255)
)
WITH (MEMORY_OPTIMIZED=ON)
GO

CREATE TABLE dbo.Table2 (
   Id_tb2 int not null primary key nonclustered hash with (bucket_count=4096),
   Int_Val int not null,
   CreateDate datetime2 not null,
   Id_tb1_fk int,
   index ix_Int_Val nonclustered hash (Int_Val) with (bucket_count=4096)
)
WITH (MEMORY_OPTIMIZED=ON, DURABILITY=SCHEMA_ONLY)
GO

In memory tables have a durability property that can be set to SCHEMA_AND_DATA or SCHEMA_ONLY. There are two new columns in sys.tables to track this. SCHEMA_ONLY tables are volatile, SCHEMA_AND_DATA are persisted to disk.

SELECT name,type_desc,durability_desc FROM sys.tables

The hash indexes can be tracked with a new catalog view.

SELECT * FROM sys.hash_indexes

DML.

The two big selling points of in memory OLTP are improved performance with entirely memory resident data accessed with hash indexes and use of an optimistic multiversion concurrency control … no locking.

So let’s run some DML and test this out. Insert a row:

BEGIN TRAN

INSERT dbo.Table1 VALUES (1,427,getdate(),'Insert transaction')

SELECT * FROM sys.dm_tran_locks WHERE request_session_id = @@SPID
SELECT * FROM sys.dm_db_xtp_transactions

COMMIT TRAN

The sys.dm_tran_locks DMV will return a shared object lock and a Schema shared lock on the database. The new sys.dm_db_xtp_transactions is a new DMV for in memory OLTP and returns information about current transactions against the database.

Now run an update inside an explicit transaction. Note that we will get an error if we don’t use the WITH(SNAPSHOT) hint.

BEGIN TRAN

UPDATE dbo.Table1  WITH (SNAPSHOT)
SET [Description] = 'Updated transaction'
WHERE Id_tb1 = 1

SELECT * FROM sys.dm_tran_locks WHERE request_session_id = @@SPID
SELECT * FROM sys.dm_db_xtp_transactions

In another session run a select.

SELECT *
FROM dbo.Table1
WHERE Id_tb1 = 1

The select returns the pre updated version of the row – but there is no blocking. This is achieved using a versioning system that is, despite the keyword SNAPSHOT, not the familiar SNAPSHOT ISOLATION row versioning based in tempdb. (Details of how this is achieved can be found in the readings at the end of this blog.)

Commit the update and run the following delete.

BEGIN TRAN

DELETE dbo.Table1 WITH (SNAPSHOT)
WHERE Id_tb1 = 1

SELECT * FROM sys.dm_tran_locks WHERE request_session_id = @@SPID
SELECT * FROM sys.dm_db_xtp_transactions

Note that the delete transaction is still only holding lightweight shared locks. The select in another session will now return the updated row.

SELECT *
FROM dbo.Table1
WHERE Id_tb1 = 1

Commit the delete transaction.

Concluding Remarks.

As of CTP1 not all of the features are fully working and there are a number of limitations that are likely to roll into RTM – hopefully to be slowly improved in subsequent releases. The whitepaper in the reading list below has an exhaustive list of these restrictions but one of the biggest ones for me is that foreign key constraints are not supported.

Another big feature that is available for in memory tables are the native stored procedures. I didn’t touch on these but they are tipped to offer highly optimised performance. A stored procedure that only operates against in memory tables can be marked using the WITH NATIVE_COMPILATION option and this will compile the sproc into a DLL using C code.
