I am trying setup WSO2 Governance registry with MySQL database. But it is giving me an exception,when I start start registry server with '-Dsetup' argument. I have already created database on MySQL with name 'registrydb'. Exception Given below:

You need to create the database before start the server. -Dsetup option only creates the database tables not the database it self.
problem is solved. -Dsetup argument didn't work. Solution is After creating database manually on MySQL, import 'mysql.sql' script from {REG_HOME}/dbscript. It will create and populate database tables.(Note: -Dsetup is alternative of manual step). Then start registry normally.

com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException been raised when attempting to make an SSL connection to MySQL from a tomcat-based application.
I have tried the same code in a Java class in the main method without tomcat (like a Java project in eclipse). This program works fine, i.e. I am able to get an SSL connection to the database.
Error code:

I looked for a successful encrypted connection without an exception, even in the tomcat based application.
PS: I am getting this exception with a tomcat based application, but not in non-tomcat applications. And I am using jdk 11 and tomcat 9.
I am newbie in J2EE.
I write a J2EE web application on eclipse and moved it to my Ubuntu 16.06 in which I have installed Apache Tomcat 8 and MySQL 5.7 (and I use mysql-connector-java-5.1.42-bin.jar).
I repeatedly get the following error after some (8) hours idle time:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.

I read many similar posts on SO about this issue but I was unable to solve my problem.
My context.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<Resource name="jdbc/db" type="javax.sql.DataSource"
maxTotal="100" maxIdle="30" maxWaitMillis="10000"
url="jdbc:mysql://localhost:3306/userdb?useEncoding=true&characterEncoding=UTF-8"
driverClassName="com.mysql.jdbc.Driver" username="root" password="xxxxxx"
autoReconnect="true" defaultAutoCommit="true" validationQuery="select 1+1"
testOnBorrow="true" />
</Context>
I also get following strange INFO on my catalina.out file (autoReconnect="true" was recommended by the Tomcat in error log!!!):
Jun 28, 2017 2:20:52 PM org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory getObjectInstance
INFO: Name = db Ignoring unknown property: value of "true" for "autoReconnect" property
Should I configure something like "wait_timeout" on MySQL?
.
P.S. Since my Tomcat and MySQL are on the same server, I think firewall might not be an issue.
The sonar-runner on my development vm is unable to connect to the SonarQube instance hosted in another vm. Using telnet to communicate between these 2 systems over port 9000 is successful and the sonar user has successfully logged into mysql locally.
In reviewing the errors, the development vm running sonar-runner successfully connects and downloads the jdbc driver, then fails when creating a datasource.
Any advice on further steps to troubleshoot the issue would be appreciated.

Using Grails 2.2.4 on Tomcat 7.0.47, MySQL Connector 5.1.18, MySQL 5.5.12, Windows Server 2003.
Have around 100 hosts that are queried with JMX every 2min, and SMB every 1h.
Using default pooling from DBCP. The code issues multiple threads in a loop, one for each remote host (TCP connections).
Max_used_connections in MySQL shows 503 and is near the limit set in DataSource.groovy (maxActive = 500), but I don't get "too many connections" exception.
I have those "testOn*" properties set in DataSource.groovy.
I tried increasing the number of available ports (Windows Server 2003) to 10000 and decreasing TIME_WAIT to 30, but to no avail.

I ignored it then, but maybe it has something to do with this.
Does anybody have any pointers as to what the cause of this might be and how to avoid it?
The initial exception I got before I started tweaking things was:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The driver was unable to create a connection due to an inability to establish the client portion of a socket.
This is usually caused by a limit on the number of sockets imposed by the operating system. This limit is usually configurable.
For Unix-based platforms, see the manual page for the 'ulimit' command. Kernel or system reconfiguration may also be required.
For Windows-based platforms, see Microsoft Knowledge Base Article 196271 (Q196271).

And the issue here is TCP port exhaustion. Increasing MaxUserPort and decreasing TcpTimedWaitDelay in the OS registry solved it.
It was requested from this question to post a different question.
I did as recommended in the question above and corrected the cloudbees.xml file correctly. But even then I can't connect. Here's the stack trace:

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.35 logs.
Apache Tomcat/6.0.35
This is a common MySQL connection timeout, need to configure the connection pool to check returned connection is live, read related documentation "avoiding database idle timeouts" :
use a validation query in you connection pool settings :
<param name="validationQuery" value="SELECT 1" />
you also should consider using database binding, as cloudbees-web.xml is deprecated :
bees app:bind -a APP_ID -db DB_ID validationQuery="SELECT 1"
