    HI Ashish,

     

    What action is being performed when you receive this error? (E.g., Trying to run a workbook.)

     

    Thanks,

    Rob

    No problem. =)

     

    Have you set up your database to use with Datameer? The error means that Datameer is not able to locate the database to use.

     

    Thanks,

    Rob

    Yes, I have setup MySQL database and granted all permissions to it.

    I have followed installation steps properly as given in the link below

    Could you try checking the database status by running the command below and posting the results.

    mysqladmin -u root -p status

     

    Thanks,

    Its resolved...

     

    I  installed Data Meer and MySQL on remote machine and while running conductor script ,I used localhost.

    I changed localhost to address of MySQL node and it worked.

     

    Thanks

    Ashish
