I was looking around for some solution to bring TDE to MySQL. I found this question asked in here before.
But the question seems to be about enabling a TDE solution to a MySQL database that is installed in a Linux environment.
In my case, I would need a TDE solution for MySQL that is installed in a Windows Server 2008 R2 environment.
I have found NetLib and it seems to be working for me. Question is, are there any other alternatives? Also, is NetLib good?
EDIT:
So now using TrueCrypt with MySQL is possible. But, is there any other alternative to this? One that has been audited perhaps?
MySQL doesn't care what solution you're using as long as you provide it a filesystem that acts like a filesystem. It deals only at the file level. Do understand that performance may be severely impacted, however.

Having to support an older VB.Net application, I get performance issues when several workstations are working with the MySQL database via ODBC at the same time. I'm now thinking about switching from ODBC to the MySQL Connector/NET.
I don't know Connector/NET at all. Does anybody have experiences with a switch like this? Are there any caveats? Is it even worthwile? Would it be a lot of work (the app relies heavily on MySQL)? I didn't find anything about the efford needed. Any thoughts? Thanks.
I am looking to implement some performance monitoring on my ROS server.
I'm running Ubuntu 16.04 running on a VPS. Unfortunately the VPS has no performance statistics. So I'm looking to install a tool or connect to a server that will help me understand the load the server is experiencing.
I'm specifically considering deploying Prometheus. Although it looks like quiet an effort to get it running I figure it's the most comprehensive tool available.
Before I start I want to be sure that this is achievable and it will not impact the ROS performance/capability.
Has anyone implemented performance monitoring? Did you use a particular service or tool and did you use a great document/page to help you install and configure?
Closed. See my comment, in the end I used Datadog, which appears to be very good.
Is there any way to use MySQL without install? I am making an desktop application using Visual Studio and C# that uses MySQL. I will use this program on another computer.if this computer has no MySQL installation my program will also work? Can I move my database with my application?
No, you do not need the server installed locally. You do need some sort of client, though. For C, you would need the mysqlclient library. I assume C# has something similar to enable the CLR to talk to MySQL.
If you are looking for a portable database, check out SQLite. As for the best library for C#, see these answers:
What is the best way to connect and use a sqlite database from C#
Is there a .NET/C# wrapper for SQLite?
No... You will need the computer to have mysql and your compiled code. What you CUD do if your database is not too big is hardcode the data storage and retrieval in your code itself.. in that case you wont need mysql installed there..
OR you cud allow network access to mysql on another machine(server) in that case u only need mysql on the server

I should note that I need to do this on a live production server. The MS SQL Server is already attached to our website and supports a 3rd party ERP package. I want to set up a separate database that I can code against for some auxiliary pages and internal-use apps) which will be completely independent (mostly for security, but also because I prefer mySQL) from the ERP solution.
[end edit]
The MS SQL 2005 express db is already installed and in use, so I don't want to hose it.
Will this create problems, or have you done it successfully?
Aside from performance issues, assuming they're both continuously used, there shouldn't be a problem.
For a development machine this is safe to do. The two database servers listen on different ports, so there is no problem of running both at the same time.
I wouldn't recommend it though for a production system.
Like Assaf said, the only thing you should worry about are possible performance issues with both database services getting run at the same time. Other than that you should have no worries concerning the integrity of the two. They are completely separate and should not have any sort of conflicts.
Microsoft has chosen to not release a 64-bit version of Jet, their database driver for Access. Does anyone know of a good alternative?
Here are the specific features that Jet supports that I need:
Multiple users can connect to database over a network.
Users can use Windows Explorer to copy the database while it is open without risking corruption. Access currently does this with enough reliability for what my customers need.
Works well in C++ without requiring .Net.
Alternatives I've considered that I do not think could work (though my understanding could be incorrect):
SQLite: If multiple users connect to the database over a network, it will become corrupted.
Firebird: Copying a database that is in use can corrupt the original database.
SQL Server: Files in use are locked and cannot be copied.
VistaDB: This appears to be .Net specific.
Compile in 32-bit and use WOW64: There is another dependency that requires us to compile in 64-bit, even though we don't use any 64-bit functionality.
Luckily, things have changed in the past two years:
Since Office 2010 is available in a 64-bit version, Microsoft had to create a 64-bit version of their Jet Engine. According to the Microsoft Customer Service blog, the Microsoft Access Database Engine 2010 Redistributable contains a 64-bit driver, which is able to access recent versions of the Microsoft Access database format.
Users can copy the database while it is open without risking corruption.
You can't do that with any database file with multiple users and/or processes modifying it.
What you're looking for is SQL Server Express with the portable .mdf files. To get around the copying limitation you need to make sure that the software in question doesn't keep connections open (i.e. create a disconnected data access layer).
Try to have a look at http://www.vistadb.net/
#Orion: Agreed, OP would be advised to go with SQL 2005 Express (if possible). The deal breaker is being able to copy the DB while in use/attached which is out of the question with SQL without using some kind of backup tool that can copy 'in use' files.
Another way would be to automate a backup and restore to roaming machine but this is getting a long way away from being able to just grab a copy of the file.
Another alternative you can look at is SQL Server Compact Edition (CE). I believe this has 64bit binaries.
I also agree with Orion and Kev about the copying the database.
What I am going to do is to create a separate 32-bit executable that connects to Jet that my 64-bit application can communicate with through COM.
This satisfies my general requirement of "work like Jet", because it is Jet. My customers don't get the benefit of 64-bit, but the other requirements are more important.
