I'm trying to create datasource for connection pooling mysql database in Websphere Application Server.
I've set the JDBC Provider, I set the
Implementation class name : com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource
my mysql driver version is 5.1.6.
but I got this error while I try to connect the datasource:
The test connection operation failed for data source btn_itb_ds on server server1 at node qnode with the following exception: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Unknown command. View JVM logs for further details.
I have read this http://bugs.mysql.com/bug.php?id=38388 trouble shooting. But they just suggest to upgrade mysql driver version 5.1.X and I have do that. but I've got the same error.

I'm using MYSQL Workbench version 8.0.26 in my server dump in version 5.6.10. I already have the option in the Manage Server Connection "Use SSL = NO", but whenever i connect into it and try to EXPORT DATA, the process fails and the following error is presented:
mysqldump: Got error: 2026: SSL connection error: error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol when trying to connect
Already tried to reinstall or disabling the SSL again, but no success, still the same error, does anyone have any clue what can it be?
When i want to create a database connection from apache superset 2.0.0 on docker environment to vertica then i get this error
i already installed sqlalchemy-vertica-python library
my connection string is: vertica+vertica_python://user:passwd#host:port/db_name
I begin by starting goole sql proxy by running following command:
./cloud_sql_proxy -instances=dauntless-gate-xxxxxx:us-central1:redacted-dev=tcp:3306
I SUCCESSFULLY connect from to it from running the following commands:
mysql --host=127.0.0.1 --user=sa --password=<redacted>
or
mysql --host=127.0.0.1 --user=sa --password=<redacted>
I attempt and fail to connect using ASP.net Core 2 w/ the follwing:
startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<UserContext>(opt =>
opt.UseSqlServer("Server=127.0.0.1:3306; User Id=sa;Password=<redacted>;"));
...
}
Error:
SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 35 - An internal exception was caught)
I also try with the following and get slightly different error:
startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<UserContext>(opt =>
opt.UseSqlServer("Server=127.0.0.1; User Id=sa;Password=<redacted>;"));
...
}
An unhandled exception occurred while processing the request.

Note: User jasper_admin already exists in DB and this connection is tested successfully. Database jasper exists as-well.
I can't connect as root access! Please suggest me if there is any work-around.
Thanks a ton in advance for your help.
[update] In error log, I can see below error
Could not connect: Access denied for user 'jasper_admin'#'%' to database 'mysql'
but where I can see what code Jasper build scripts are using to verify this? because, I can connect to MySQL DB using same user via MySQL Client.
Issue was with MySQL user "jasper_admin". This user should have access to internal database mysql. Best case is try installing Jasper using MySQL "root" user.
My enviroment has the following servers: WildFly 8.0 and MySQL 5.5.32.
The database server is stopped and started every night for backup procedures. After that, I'm getting the following error in my WildFly Log:
09:52:38,136 ERROR [stderr] (default task-11) gate.error.APPLError: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.
I have five configured datasources between these servers, but only one has this problem.
I'm not using JPA.
