I've tried to follow this article http://docs.jelastic.com/jelastic-dotcms-deploy , but actually when I started application I get an error:
SEVERE: Exception starting filter URLMapFilter
com.dotmarketing.exception.DotRuntimeException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.)
I understand that there is a problem with jdbc url , but I can't fix it.
Any suggestions?
Thanks for clarifying.
Your JDBC URL should be like this:
jdbc:mysql://mysql-env-giph.j.rsnx.ru/dotcms
Note the mysql- not mysql.
EDIT: http://docs.jelastic.com/connection-to-mysql may help to clarify it further (in the docs, the environment name is "mysqlconnection", so they use "mysql-mysqlconnection" for the MySQL server.
The format is always like this:
host=jdbc:mysql://mysql-{your_env_name}.{hoster_domain}/{db_name}

Could you please help me with the correct URL format to connect to Sybase using the DBCP connection pool of NiFi?
The URL format that I have tried is - jdbc:sybase:Tds://host:port
I keep getting this error - failed to create Poolable Connection Factory. Incorrect URL format.
Thank you in advance.
Am trying to connect vertica from DBeaver, but am getting below connection error. Initially it was working fine, but suddenly its throwing connection error.
Error Message:
[Vertica][VJDBC](100071) GSS authentication failed due to problems establishing a TGT with JAAS using configuration verticajdbc; reason: Message stream modified (41).
Message stream modified (41)
Message stream modified (41)
I am not able to establish the connection now. Can anyone please help me on it.
The main issue I see with vertica users struggling to connect relate to the drivers used or where the host has changed. Have you updated vertica recently or has there been a change to the host name are just a couple of things you should check.
Sorry I cant be more specific its hard to troubleshoot when I dont have all the information.
Thanks
For JDBC request on Jmeter I have configured properly Database Connection Configuration with giving
Database Url- jdbc:mysql://developmentdb.cwwxeukesrtn.ap-southeast-1.rds.amazonaws.com;Development_DB
JDBC Driver Class- com.mysql.jdbc.Driver
Username-...
Password-...
then I create a JDBC request with Select Statementbut after run this request,on the response message got this message-
Response message:
java.sql.SQLException: Cannot create PoolableConnectionFactory (Communications link failure The last packet sent successfully to the
server was 0 milliseconds ago. The driver has not received any packets
from the server.)
Now my question is , how to solve this problem?
You need two basic things to get that done:
Tunneling
mysql.jdbc jar in JMeter lib folder.
For 1st:
Open Putty
Go to Connection >> SSH >> Tunnels
Put down the details as port: 9876
Put down the details as database URL (present in the application config file), e.g:
jdbc:mysql://developmentdb.cwwxeukesrtn.ap-southeast-.rds.amazonaws.com;Development_DB
Add it
Open JMeter >> Add JDBC Connection Configuration
Use DataBase URL as jdbc:mysql://localhost:9876 and the
other details as shown in the picture, like JDBC driver Class
For step 2. Go through this link:
https://www.blazemeter.com/blog/mysql-database-and-jmeter-how-to-test-your-connection/
Looking into Driver/Datasource Class Names, URL Syntax and Configuration Properties for Connector/J article:
I believe you need to replace the semicolon before Development_DB with a slash like:
jdbc:mysql://developmentdb.cwwxeukesrtn.ap-southeast-1.rds.amazonaws.com/Development_DB
For more information on databases load testing see The Real Secret to Building a Database Test Plan With JMeter article.
You might also need to open port 3306 in your operating system firewall and add the relevant Security Group to your instance in order to allow MySQL JDBC traffic.
I'm newbie to the orientdb, I'm using netbeans's (add new connection wizard) to add a connection to the orientdb, I used orientdb-jdbc-2.0.2-all.jar as a jdbc driver, but I got the following error after clicking on test connection
Snapshot of the error
I made sure that the database is connected and everything is right, any idea?
The URL should be jdbc:orient:remote:localhost/Sensor_Data
Look at the documentation: http://www.orientechnologies.com/docs/last/orientdb-jdbc.wiki/Home.html#first-get-a-connection.
the problem should be in the connection port. You are using 2480 (HTTP port) instead of 2424 (binary protocol).
When standalone client and jboss server runs on the same machine, everything works fine, but when i try to run the JBoss on a VM, i can get a JNDIContext from the Server,i can do a successful lookup, but i cannot establish a connection.
The Client throwing an exception as:
Exception in thread "main" javax.jms.JMSException: Failed to create session factory

And the server End showing msg as,

I have seen other posts also related to this issue , but I didnt clear with the solution . So Plz help me out and forgive me If I am asking silly question since I am new in this domain.
Thanks.
You have to configure the port on the server. You probably have the server starting as localhost and you are connecting externally, in such way the JNDI can connect but not the HornetQ connector.
You certainly have a configuration error, but without knowing version, what actual message you got and configuration options I have little information to help you more beyond that.
