Hi all , got following error while executing the jobs on PDI .
i do have mysql driver in place (libext/JDBC) . can some one say , what would be the reason of failure .
By error i came to know , error while connecting to DB , but my DB is up , i can access it by cmd prompt .
Error occured while trying to connect to the database
Error connecting to database: (using class org.gjt.mm.mysql.Driver)
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.
