Having connection issue while connecting to MariaDb Galera cluster using mariadb jdbc connector plugin - galera

Error: org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is java.sql.SQLNonTransientConnectionException: (conn=6037539) Client does not support authentication protocol requested by server; consider upgrading MySQL client
Mariadb Client I am using:
<dependency>
<groupId>org.mariadb.jdbc</groupId>
<artifactId>mariadb-java-client</artifactId>
<version>3.1.0</version>
</dependency>
Connection String:

Can anyone help me solve this why the spring boot application using the mentioned jdbc client cannot make a connection to the database.

Liquibase update for database over secured connection

We are using liquibase maven plugin to execute changelogs in database. We have been told to use connection over TLS. Our services are successfully connecting to database using Java Keystore and Trust Store. But we are facing issue while executing liquibase over CLI. Can you please help how to execute liquibase over CLI for database connection over TLS.
Liquibase does not have a setting to configure the TLS. It is something that ins typically on figured in Oracle (in sqlnet.ora or on the client side using security.java)
If you need to set up Oracle wallet which is sometimes the case with using TLS, you can refer to this documentation: https://docs.liquibase.com/workflows/database-setup-tutorials/oracle-atp-db.html

How to configure HikariCP with EclipseLink JPA

I am upgrading my (old) application (JSF/Java) that uses HikariCP as its connection provider. Now I would like to use JPA and EclipseLink. Any suggestions on how to use HikariCP with EclipseLink?
On the HikariCP, there is only a configuration for Hibernate: https://github.com/brettwooldridge/HikariCP/wiki/Hibernate4
How could I do the same in EclipseLink?

DAL01013: Cannot connect to server

I'm trying to connect to DB2 db but getting the error:
DAL01013. Cannot create connection to server 'Unknown server' due to the following: [jcc][t4][2034][11148][3.69.24] Execution failed due to a distribution protocol error that caused deallocation of the conversation.
A DRDA Data Stream Syntax Error was detected. Reason: 0x3. ERRORCODE=-4499, SQLSTATE=58009
Assume it's something with my system. I cannot connect neither via DataStudio nor via QMF. Other users from other system can. I use same jdbc drivers. My system is Windows 7.
Is there anything else I need to adjust on my system?
Personal repository needs to be created first:
https://developer.ibm.com/answers/questions/470013/error-when-trying-to-connect-to-db2-vis-qmf/
Generally you get the reason 0x3 from error -4499 out of the IBM JDBC driver when you are connecting to a SSL port, but you have not specified sslConnection=true on your JDBC connection string. You can also get the error if your database name is incorrect (i.e. does not exist on the server), or your JDBC dirver is too old (DB2 JDBC Driver Versions and Downloads Download Fix Packs by version for IBM Data Server Client Packages)
If connecting to Db2 on Cloud, Db2 Warehouse or Db2 Warehouse on Cloud, all you should need is the sslConnection=true as the CA certificate used in these products is part of the Db2 driver package (for recent drivers anyway)
If connecting to Db2 on premise, you can specify your certificate location via the JDBC properties sslCertLocation or sslTrustStoreLocation and sslTrustStorePassword
Common IBM Data Server Driver for JDBC and SQLJ properties for all supported database products
sslCertLocation
Specifies that an application can configure the location of a trusted certificate file. For applications that have the database server certificate, sslCertLocation is the only property that is needed to be configured to instruct IBM Data Server Driver for JDBC and SQLJ to trust the certificate for SSL connections.
This property removes the need to import the certificate into a Java truststore database and related driver configurations.
Error codes issued by the IBM Data Server Driver for JDBC and SQLJ
error codes in the ranges -4200 to -4299, and -4450 to -4499 are reserved for the IBM® Data Server Driver for JDBC and SQLJ.

weblogic jdbc Datasource error BEA-001131 Closed Connection

I have Installed weblogic 10.3.5 with jrocket 1.6.0_33. Oracle Fusion Middleware 11.1.1 on Windows Environment. On database side I have Oracle database 11gR2 RAC environment with Two instance on Linux Environment. I have created
GRIDLINK DataSource with XA DRIVERS.
NAME: test
JNDI: jdbc/testDS
NOTE: I have used SCAN IP for this DataSource configuration.
FAN ENABLED checked.
ONS HOST : scan-ip:6200
Not using "ONS Wallet".
DataSource was created successfully. Testing is done. Now when I start Application for 1st time and Click on any TAB, The Managed Server through some error on its console screen.
<error> <JDBC> <BEA-001131> <Received an exception when closing a cached statement for the pool "test": SQLRecoverableException: Closed Coonection.>
What should I do to resolve this error.
You should discover what's really happening when you enable debug on the weblogic instance in question. Here are the flags you can setup on server start as arguments.
-Dweblogic.debug.DebugJDBCRAC=true
-Dweblogic.debug.DebugJDBCONS=true
-Dweblogic.debug.DebugJDBCUCP=true

is it not possible to deploy mule application in server if database connection fails

My Database server is down.. When I try to deploy mule application in mule standlone server, application is not getting deployed because jdbc connector could not connect to database..Even if jdbc connection fails to database, that should not stop application to be deployed.How to implement this?
Initialize the Datat Source with dummy values.
I guess deployment is getting failed because of DataSource initialization,
not because of Connector
