ispyb-database

This package provides everything needed to create the official flavour of the ISPyB database schema. As the schema evolves the update scripts will also be published here, so other users of the schema should be able to stay up-to-date.

Browsable documentaion with relation diagrams is available on dbdocs: https://dbdocs.io/ispyb/ISPyB

This repository is mostly copied from ispyb-database. Thanks to @karl.levik

Requirements

• Server and a client packages of MariaDB 10.3 or later.
• A Unix-like OS with bash shell.
• The pandoc package (only required to build documentation at the end of the build.sh script.)
• If binary logging is enabled in the DB system, then execute this before importing the test schema: SET GLOBAL log_bin_trust_function_creators=ON;

Installation

1. Install MariaDB.
2. Copy examples/.my.cnf to .my.cnf and then edit that file to set the user and password, e.g. user = root and use the password you set when securing. Optionally, you can also set e.g. host and port.
3. In a test environment run the scripts/build.sh file. This creates the database schema and applies the grants as described in the "Schema" and "Grants" sections below.

Schema

Tip: Execute ./build.sh to create a development ispyb_build database and import all the schema and grants files into it.

Alternatively, do it manually:

Run this on the command-line to create a database and import the schema stored in the SQL files:

mysql -e "CREATE DATABASE ispyb"
mysql ispyb < schema/1_tables.sql
mysql ispyb < schema/2_lookups.sql
mysql ispyb < schema/3_data.sql
mysql ispyb < schema/4_data_user_portal.sql
mysql ispyb < schema/5_routines.sql

Note that the 3_data.sql and 4_data_user_portal.sql files contains test data, so is only useful in a development environment.

Grants

Then apply the grants:

mysql ispyb < grants/ispyb_acquisition.sql
mysql ispyb < grants/ispyb_processing.sql
mysql ispyb < grants/ispyb_web.sql
mysql ispyb < grants/ispyb_import.sql

Note that the grants files are based on roles, so to actually use these grants, you also need to create database users and grant the roles to them. This is described in the header section of the grant files.

Miscellaneous Notes

In a development environment it might be useful to log all SQL errors. In MariaDB, you can install the SQL Error Log Plugin to get these logged to a file sql_errors.log inside your datadir. Run this from the mariadb command-line:

INSTALL SONAME 'sql_errlog';

You can verify that it's installed and activated with:

SHOW PLUGINS SONAME WHERE Name = 'SQL_ERROR_LOG';

Updating

In order to update a production database, please follow this procedure:

1. For all .sql files in schema/updates that have not already been run, read any comments inside the files to decide if/when you should run them. Run a file e.g. like this:

mysql ispyb < schema/updates/2019_03_29_BLSession_archived.sql

2. If schema/routines.sql has been updated since you installed it, you can simply re-run it. E.g.:

mysql ispyb < schema/routines.sql

3. If you ran the routines.sql, then re-apply the grants for the routines. E.g.:

mysql ispyb < grants/ispyb_acquisition.sql
mysql ispyb < grants/ispyb_processing.sql
mysql ispyb < grants/ispyb_web.sql
mysql ispyb < grants/ispyb_import.sql

Useful scripts

• scripts/build.sh: Creates a development ispyb_build database and imports all the schema and grants files into it.
• scripts/missed_updates.sh: Generates a list of files in the schema/updates/ folder that haven't been applied.
