Unable to connect to MySQL in Cloudbees CommunicationsException: Communications link failure - mysql

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:

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"

Amazon Aurora DB operation failing with Socket timeout exception

Recently we upgraded our spring boot application from 2.3.4 to 2.6.7
Our spring boot application uses Aurora DB instance with Maria DB driver.
According to latest AWS documentation,https://aws.amazon.com/blogs/database/using-the-mariadb-jdbc-driver-with-amazon-aurora-with-mysql-compatibility/, Maria DB driver is no longer compatible with Aurora DB.
Hence we decided to switch it to AWS Mysql driver with Hikari connection pool.
After the change, long running queries are timing out resulting in socket timeout exception.
We tried with the jdbc url parameter connectionTimeout=0 and socketTimeout=0 but still we are getting socket timeout exception.
Any suggestions here?

MySQLNonTransientConnectionException when getting ssl connnection to mysql from tomcat application

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:
DriverManager.getConnection("jdbc:mysql://localhost:3306/ibisdb74?verifyServerCertificate=true&useSSL=true&requireSSL=true&clientCertificateKeyStoreUrl=file:/home/directoryA/mysql_certs_latest4/keystore&clientCertificateKeyStorePassword=mypass&trustCertificateKeyStoreUrl=file:/home/directoryA/mysql_certs_latest4/truststore&trustCertificateKeyStorePassword=mypass","root","root");

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 have checked the data source configurations with WSO2 DSS that works perfectly. MySQL connector jar is also placed in repo/component/lib. Here is the configuration of data Source:
<datasource>
<name>WSO2_CARBON_DB</name>
<description>The datasource used for registry and user manager</description>
<jndiConfig>
<name>jdbc/WSO2CarbonDB</name>
</jndiConfig>
<definition type="RDBMS">
<configuration>
<url>jdbc:mysql://192.168.1.117:3306/registrydb</url>
<username>waqas</username>
<password>waqas123</password>
<driverClassName>com.mysql.jdbc.Driver</driverClassName>
<maxActive>50</maxActive>
<maxWait>60000</maxWait>
<testOnBorrow>true</testOnBorrow>
<validationQuery>SELECT 1</validationQuery>
<validationInterval>30000</validationInterval>
</configuration>
</definition>
</datasource>

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.

SonarQube Runner - JDBC Error: Communications Link Failure

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.
