Thread: Pentaho configured with Mysql gives communication link error.

  1. #1

    Default Pentaho configured with Mysql gives communication link error.

    Hi,

    I have configured pentaho bi server 3.10 with mysql. I am able start application and view my reports. But after some 5 mins or so I start getting errors saying no operations permitted after Connection closed.
    On restarting the server the application works fine for some 5 mins but after that the same error.
    I am getting communication link fail error saying connection has been closed and some time since last packet was recieved.

    Below is the stack trace:


    11:21:33,819 ERROR [JDBCExceptionReporter] No operations allowed after connection closed.

    Hi Ankitshah,

    Probably your MySQL server is closing the connection due to timeout.
    You have 2 choices:
    - either increase the timeout period in your MySQL server
    - or replace the mysql driver with c3p0. It is a very good tutorial in the forum how to write the c3p0.hibernate.cfg.xml.

    Thanks everyone.
    Connection timeout from mysql server seems to be the issue.
    Right now i have reverted back to use hsqldb.
    Will take a try by configuring c3p0.
