Upgrading to version 7.2

To increase the efficiency in workbooks, filter (FilterSheetType) and sort (SortSheetType) sheet types are no longer supported. These sheet types have not been used as of Datameer 2.1 though users that have upgraded from 2.1 or earlier versions may still have these sheet types within their older workbooks. Users with these sheet types in their database first need to upgrade to an staging version Datameer which migrates the filter/sort sheet type into a formula sheet type. After upgrading to Datameer 6.3, 6.4, 7.0 or 7.1, it is safe to upgrade 7.2.

For those upgrading to 7.2 that had the filter or sort sheet types converted into formula sheet types, workbooks do not display preview data in those sheets until the workbook has run again. If you are upgrading to Datameer 7.2 from a 6.1.x or earlier version, must first upgrade to a 7.1.12 or later 7.1.x release, in order to trigger an important Database schema migration processes.

How to Roll Back to a Previous Database Version

When upgrading, a database dump is created by Datameer, the file name is similar to mysql_db_dump_<oldVer>.sql. If an upgrade failed (failing upgrade scripts / failing upgrade injectors during startup), the database paths might be conflicting, it is therefore necessary to restore the Datameer MySQL database dump. Follow the steps to complete this task.

  1. Drop the new database, for example on the database server or the MySQL CLI.

    No Format
    DROP DATABASE dap;

     

  2. Using the mysql-init.sql script, create a new database.

    No Format
    mysql [-h <dbhost>] -u root -p < bin/mysql-init.sql

     

  3. Import and restore the previous database using the following shell command.

    No Format
    mysql [-h <dbhost>] -u root -p dap < /path/to/dump_file_name
