Subject RE: Unable to start MySQL in NetBeans
Date Thu, 26 Apr 2018 13:20:26 GMT

I am using NetBeans 8.2 on a Windows 10 64-bit PC.

The Java version I have is 9.0.4 64-bit.

Many thanks

Martin O’Shea.

Hi Martin, I will try it.  There are several methods to configure the start and stop process
and it is platform dependent.

You can use configuration files or scripts.

I will get back to you later.  I am working now and will resume this later.

What is your configuration again and platform?  I have Windows, MacOS, Linux 64-bit, and Linux

The other information I sent was from my Windows system.

For all of the connections I have, there does not seems to be any issue now connecting to
MySQL 8.0.11 in NetBeans 8.2.

But, I still cannot connect via the Start or Connect options on the context menu shown below:


The messages I get are those described below in an earlier post. Prior to this new version
of MySQL, the MySQL Server icon above in NetBeans would always be connected by default. This
is what I am trying to resolve now.

Okay, I did not mention this but I removed the last part of the connection string on the driver.

Old string:  jdbc:mysql://localhost:3306/test?zeroDateTimeBehavior=convertToNull

New string:  jdbc:mysql://localhost:3310

I am using port 3310 for MySQL 8.0.11.

After connecting, I noticed the system changed a setting to:

Display name:  jdbc:mysql://localhost:3310/dbtest?zeroDateTimeBehavior=convertToNull [root
on Default schema]

This will show once you connect to a database in my case I am connected the dbtest
Database URL: jdbc:mysql://localhost:3310/dbtest?zeroDateTimeBehavior=convertToNull

I have been trying your suggestions in the last 30 minutes:

I am able to create connections in NetBeans 8.2 to MySQL 8.0.11 using both connectors 5.1.46
and 8.0.11 and can execute SQL commands:


So that is an improvement in my situation.

However, what I have not been able to do so far is register MySQL 8.0.11 in NetBeans 8.2 itself,




The results is:


Then, if I try to start MySQL in NetBeans from the context menu, I receive the prompt:


And messages:

Yet table mysql_plugin does exist under 8.0.11.

Similarly when trying to connect to the registered version of MySQL, I receive:


Have you any idea about these at all?

Hi all:
I have the following running on this system concurrently MySQL 5.6 on port 3308, Maria DB
10.x on port 3306, MySQL 8.0.11 on port 3310, and Oracle XE Express on port 1521. Several
Apache & Tomcat servers running on different ports and all working.

Tested on NB 9.0 build 413 using MySQL 8.0.11 using legacy
authentication.  This works!

Pictures for proof.
