I have made a web page which uses a local SQL database server.
Now that I want to publish the web page and place it online, I have to change everything, because the hosting server uses mySQL and presents me with his own mySQL database, and I don't know how to make that transition, I have an entity model in my solution and the Controller my database.
The specific question is - what are the steps to make that transition?
1 use SQL Tools (don't know what version you have) do a full backup.
2 from the new hosting server, restore the database.
3 change your connection strings or path (depends on programming environment) to use new MySQL.
Here is a link to what I used when I migrated in a similar way as to automate the whole process(Yes, it took a little learning but worth it). https://www.youtube.com/watch?v=rpPANKhbpDs

MySQL Workbench provides you with the Migration Wizard feature. It allows you to migrate databases from various RDBMS products to MySQL.
This documentation would help you get started,... http://mysqlworkbench.org/2012/07/migrating-from-ms-sql-server-to-mysql-using-workbench-migration-wizard/
There are also several paid tools available which convert MS SQL to MySQL, but I've never used them personally. These tool come with free trial so you can actually test them before purchase. You can also refer similar threads on Stackoverflow,...
How to migrate SQL Server database to MySQL?
How to export SQL Server database to MySQL?
tl;dr: SonarQube calculates lines of code metric for some projects but not others after an upgrade.
Hello everyone,
I recently took over an orphaned SonarQube 5.1 installation running on MySQL 5.1 on another server. When I upgraded SQ to 5.6.2 it told me that it required MySQL 5.6. Because the servers in question are CentOS 7 that version of MySQL is not available through yum. Use of yum is required for installing software. I installed PostgreSQL on the SQ server and, because I did not want to lose SQ history and configuration, migrated the database from MySQL to Postgres using pgloader (see pgloader.conf in code block below). The migration appeared to have worked as the schema changes 5.1->5.6.2 succeeded as did 5.6.2->6.1.
LOAD DATABASE
FROM mysql://USER:PASSWORD#mysqlhost.my.com/sonar
INTO postgresql://USER:PASSWORD#pghost.my.com/sonar
with create indexes, preserve index names;
However, some projects that existed before the upgrade and migration and also some projects that have been added (through Jenkins) after the migration never have the Lines of Code metric calculated. These are primarily but not exclusively C# files.
I don't see any way to "reset" a project in the UI or web API. If I could export the SQ configuration, I would wipe the database and reload, but I don't see a way to do that either. Starting from scratch is undesirable. Any help is greatly appreciated.
I have a task to Migrate MySQL DB to Oracle (its my requirement) i tried to Migrate using SQL developer as defined in below link.
https://www.packtpub.com/books/content/migrating-mysql-table-using-oracle-sql-developer-15
As the DB is huge, the constraints are not copied properly from MySQL to Oracle, i need to define/alter/add constraints explicitly, which is time consuming (SQL developer migrates data 300rec/min from mysql to Oracle) & the entire procedure, views, functions is need to re write.
How can i ensure that data has migrated properly or not.?
Is this is a right approach to migrate?
Should i move to any tool which helps to Migrate? If yes please suggest the tool..!!
Or it is the right thing to Move from MySQL to Oracle.
Thanks in Advance.
No specific answer, but some genaral thoughts based on my experiences with migration.
I've found that there normally isn't one tool that does the whole migration job well, and by whole job I mean:
Fast
Handles all data types, scenarios
And that is from Oracle to Oracle!!
Last project we tried Oracle Golden Gate, and found there were issues with that.
We always end up with a hybrid approach, somethings like:
Extract all DDL manually and pre-create objects - there are weaknesses in the stagndard tools that confound them when extracting DDL, e.g. we found 10g expdp did not handle some quirky PLSQL well, so we resorted to extracting this ourselves.
Some tables work well with SQL Loader, others with GG, others (rare) with a custom extract and load process. We had over 3,500 tables and identified about 100 that worked better done as SQLLoader rather than GG. When I say better I mean with data handling and speed of migration. We created different groups of processing each group having a different method.
Once we have an overall hybrid scheme that works, we tune, mainly by splitting that task into parallel processes, both the export and import side.
All my migrations have been big projects where we have shifted from one Oracle system/server to another, always with the target being a newer version of OS and Oracle.
So, I would imagine that migration between non-Oracle and Oracle will through up even more challenges, and probably not as trivial as imply clicking a few buttons in SQL*Developer.
You may find the expected content from the SQL developer documentation at the Oracle website.
There are migration information available for all Microsoft Access users, MySQL users, Microsoft SQL Server and Sybase Adaptive Server users.
You can also download the tutorial in forms of PDF (best for offline viewing and printing), ePub (best for most mobile devices) and Mobi (best for Amazon Kindle devices).
Recently, I have successfully migrated the MySQL database to Oracle database. Below are detail steps:
Operating System: Desktop Ubuntu local and Desktop Ubuntu on amazon aws
Please Note: Here I am using aws desktop ubuntu server because my mysql
database was pretty big. In my case there were 800 tables, 200 views,
procedures, triggers, and functions. The total size of the database was almost
20GB. In case of small database I would recommend to use local ubuntu server.
Tools Used: SQL Developer, VNCServer, Remote Desktop Client, JAVA 8, Third Party MySql JDBC Driver
1. Setup ec2 ubuntu desktop server : https://www.youtube.com/watch?v=ljvgwmJCUjw
2. Install SQL Developer on #1
Download the SQL Developer package from this link :
http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html
Accept the license agreement and download "Other Platforms" for ubuntu.
Install the SQL developer package as the following.
sudo apt-get install sqldeveloper-package debhelper openjdk-7-jdk
openjdk-7-jre icedtea-7-plugin
Now all that you need to do is to run the command (you might have a
different version)
make-sqldeveloper-package sqldeveloper-4.1.3.20.78-no-jre.zip
This will generate a debian package that you can use to install SQL developer.
Now install the resulting .deb package using the command (Your deb
might have a different version too)
sudo dpkg -i sqldeveloper_4.1.3.20.78+0.2.4-1_all.deb
In my case, I have used java 8.
3. Once you have done with your SQL developer installation on your newly created ec2 instance with VNCServer then all you need to do is to connect to that ec2 instance with the Remote Desktop Client by default available in your ubuntu local machine.
Use IP:1 with user/pass setup for VNCServer in #1
You can see the remote ec2 ubuntu desktop server. You have to grab the keyboard inputs from the Remote Desktop tool if you want to tab inside the remote server.
Once you get connected with the remote client, open SQL Developer from the terminal or from the explorer.

Follow the migration steps provided by Oracle corporation:
http://www.oracle.com/technetwork/database/migration/mysql-093223.html
Please Note: While following the migration steps provided by the
oracle they will ask for the destination database connection i.e. oracle
database connection. This is not the database where your MySQL
database will be migrated. Instead, this database connection will
be used for the migration process. Your database connection user
must have user and database create privileges. Once your connection
have user create privilege, then migration process automatically create
the corresponding database user in Oracle database[if you have mysql_test_db in MySQL
database, same mysql_test_db will be created in Oracle db too].
I recently used sqline's tool http://www.sqlines.com/cmd to convert a dump from mysql in the form of an .sql script to an (almost) Oracle-compatible sql script.
sqlines31113\sqlines.exe -s=mysql -t=oracle "-in=$infile"
I just had to (semi-manually) fix some things in the output and then I could run it on my oracle database.
I've been searching for automatic solution to repair and analyze, optimize and check mysql databases all-in-one with a click, with ability to keep reports, and can be scheduled in task scheduler, I've found a lot of solution but all for Linux, and all command line based..
my need is to have small windows solution for this, server is windows server 2012 and using mysql that have several live databases needs automatic maintenance each while
Automatic backup batch for windows is available, but for maintenance and the above mentioned commands, couldn't find anything related to windows
anybody faced this and can help?
thanks in advanced
I understand that Oracle will at some point add support for MySQL to its Enterprise Manager software. However I'd like to know perhaps from other Oracle to MySQL migrants what tools are available for monitoring the queries, activity and resource usage happening on a MySQL database instance.
Take a look at MySQL Enterprise Monitor
One option would be MySQL Workbench 5.2. It's still in Beta but development is moving rapidly. They are replacing the old MySQL administrator with this all in one tool.
