I'm trying to connect MySQL database to weblogic so that I can use it in my project, I'm very new to this, anyway, I have created a data-source, I selected MySQL as a database type > I put my database name, host: localhost, port:3306, database username, and password, driver class name: com.mysql.jdbc.Driver
when ever I test connection it gives: Cannot load driver: com.mysql.jdbc.Driver
I downloaded J-connector I have put it in:
C:\Oracle\Middleware\wlserver_10.3\server\ext\jdbc\mysql
But it's not working!
What version of mysql are you using?
If it is version 8 of mysql you must update the driver in the Weblogic. In this link https://dev.mysql.com/downloads/connector/j/

I have an instance of Apache NiFi running on the windows machine. I have failed to connect it with the MySQL database which is running on localhost and is accessible from any host.
I have attached the configurations of the connection
I tried to change the class name from com.mysql.jdbc.Driver to com.mysql.cj.jdbc.Driver and vice-versa without success, I also tried to change the Database connection URL port from 3306 t0 33061 and vice-versa also without any success.
on the bulletin board am getting the error "No suitable driver for the given Database Connection URL: No suitable driver for the given Database Connection URL and the status is stuck on enabling even after restarting the apache NiFi.
Please assist am stuck in here.
ps: I don't have password set for the root user of my database
typo in url - you have jbds instead of jdbc
I am using laravel homestead on linux and when I want to connect to database with phpstorm or DBeaver I receive:
[08001] Could not create connection to database server. Attempted reconnect 3 times. Giving up.
Index 5 out of bounds for length 5.
I investigate and find that problem could be with jdbc driver but all of my drivers are up to date. On homestead I use mysql 5.7 and both (phpstrom and DBeaver) are up to date.
I finally figure out. For homestead on linux you need to pass this credentials:
host: 192.168.10.10
instead of 127.0.0.1 or localhost
username and password are the same: homestead and secret
I am trying to migrate a SQL Server 2008 database to MySQL. The MySQL database is on a vps on digital ocean. In the migration process, the source selection was successfull but the target selection is not. For the target selection, I used the connection method as Standard TCP/IP over SSH. Clicking on Test connection gives the error "Unsupported connection method. MySQL connections over SSH are not supported in this version of MySQL workbench migration wizard."
I have MySQL version 6.1
These are the parameters I used:
SSH Hostname: host IP address:22
SSH Username: root
SSH Password: host password
SSH KeyFile: I did not set up a key file for my MySQL db. Is it required?
MySQL HostName: 127.0.0.1
MySQL Server port: 3306
username: root
password: password to MySQL
Please tell me if I am missing something or if I am giving the parameters wrong.
Do I have to set the ssh key file to migrate the database over ssh?
Note
The migration process does not support source or target RDBMS connections through SSH.
A workaround is to set up an encrypted tunnel, and then treat the MySQL target as a standard TCP (unencrypted) connection.
I found this note on the MySQL Workbech documentation for migration wizard. Heres the link
http://dev.mysql.com/doc/workbench/en/wb-migration-install.html
I do not know how to do the migration with the suggested work around. Any help will be greatly appreciated.
Thanks.
This is what I did:
First, Install MySQL on the same machine where the MS SQL Server database exists. Use the MySQL Migration wizard to migrate the database locally. Now there are two options here.
OPTION 1: Create a backup file for the migrated database in MySQL. Use this backup file and restore database in the target MySQL.
OPTION 2: Export each table from the migrated database in MySQL to .csv files and then copy these files to the server and import them in to the target MySQL database.
I want to access sql database remotely from play framework version 1.2.4
I am running play in virtualbox and I have mysql database in local pc.
app/conf/application.conf
db.url=jdbc:mysql://xxx.xxx.47.78:3306/vedb
db.driver=org.postgresql.Driver
db.user=root
db.pass=aaa123aaa
/etc/mysql/my.cnf
bind-address=xxx.xxx.47.78
when I start the app with http://localhost:9000/ I am getting below error
A database error occured : Cannot connected to the database,
Communications link failure The last packet sent successfully to the
server was 0 milliseconds ago. The driver has not received any packets
from the server.
In your example you define a mysql URL but set the driver to postgresql...
Try to comment the driver setting, or set it to: 'com.mysql.jdbc.Driver'
You can alos try to connect to your mysql server using the mysql command line:
mysql -h xxx.xxx.47.78 -u root -p
Then enter the root password (mysql root password). This will test the network connection to the mysql server.
I am trying to connect to MySQL database using VBA from my local machine. The database is in the linux server(XXXX.xxx.edu). I have the SSH client in my machine through which I connect to the *****.xxx.edu server. Once when I login and use the below command, I am able to access the MySQL database without any problem.
mysql -p -h XXXX.XXX.edu -u username dbname
However,I need to run the VBA in my machine and insert the values into this database. I tried to connect using the code mentioned in the below link.
Error in VBA:`[Microsoft][ODBC Manager] Data source name not found and no default driver specified
As told in the suggestion of the above link, I installed the MYSQL ODBC drivers which installed the MySQL 5.5 in my machine. Even after installing, I get the error,
[Microsoft][ODBC Manager] Data source name not found and no default driver specified
I am not able to figure out what exactly is the problem. How should I connect to the linux server and then connect to the MySQL database?
you install the mysql odbc driver (the msi) from here.
http://dev.mysql.com/downloads/connector/odbc/
you run ODBC Data Source Administrator
go to System DSN
click Add
select, for instance, MySql ODBC Unicode Driver
click finish.
