PhixFlow stores configuration, analysis and task data in any of Oracle, SQL Server or MariaDB (a dialect of MySQL). For version compatability, please refer to Compatibility Guide and Upgrade PlanningSystem Requirements and Compatibility.
There are many issues to consider when installing a database, several of which will be concerned with your company’s own internal procedures, backup policies etc. The notes below describe just the core requirements which will enable the installation of PhixFlow to be completed. However, the DBA who carries out the installation should ensure that the database is configured to be performant for the volumes of data that PhixFlow is expected to process.

The following configuration parameters must be set in my.cnf | |

| binlog_format | mixed This must be added to the [mysqld] section of the my.cnf file. |
wait_timeout | 28800 (this is the default, but some installation processes set this to a much lower value) This must be in the [mysqld] section of the my.cnf file. |
| The following configuration parameters can optionally be set in my.cnf | |
| log_bin_trust_function_creators | 1 If set in my.cnf, this must be added to the [mysqld] section of the file. For details on why this setting is recommended - and the alternatives if you do not want to set in this my.cnf - see Running non-deterministic functions |

Instructions for setting log_bin_trust_function_creators in the my.cnf file are given in MariaDB installation.
Session change to allow non-deterministic functions
If you do not update the log_bin_trust_function_creators setting in my.cnf, you will need to must make sure that your session either has this setting updated, or that you run migration scripts with sufficient privileges. Full details for doing this are given in Standard Upgrade Instructions. Upgrading PhixFlow.
