Policy DB Migrator Smoke Tests
##############################
Prerequisites
*************
Check number of files in each release
.. code::
:number-lines:
ls 0800/upgrade/*.sql | wc -l = 96
ls 0900/upgrade/*.sql | wc -l = 13
ls 0800/downgrade/*.sql | wc -l = 96
ls 0900/downgrade/*.sql | wc -l = 13
Upgrade scripts
===============
.. code::
:number-lines:
/opt/app/policy/bin/prepare_upgrade.sh policyadmin
/opt/app/policy/bin/db-migrator -s policyadmin -o upgrade
.. note::
You can also run db-migrator upgrade with the -t and -f options
Downgrade scripts
=================
.. code::
:number-lines:
/opt/app/policy/bin/prepare_downgrade.sh policyadmin
/opt/app/policy/bin/db-migrator -s policyadmin -o downgrade -f 0900 -t 0800
Db migrator initialization script
=================================
Update /oom/kubernetes/policy/resources/config/db_migrator_policy_init.sh with the appropriate upgrade/downgrade calls.
The policy version you are deploying should either be an upgrade or downgrade from the current db migrator schema version.
Every time you modify db_migrator_policy_init.sh you will have to undeploy, make and redeploy before updates are applied.
1. Fresh Install
****************
.. list-table::
:widths: 60 20
:header-rows: 0
* - Number of files run
- 109
* - Tables in policyadmin
- 75
* - Records Added
- 109
* - schema_version
- 0900
2. Downgrade to Honolulu (0800)
*******************************
Modify db_migrator_policy_init.sh - remove any lines referencing upgrade and add the 2 lines under "Downgrade scripts"
Make/Redeploy to run downgrade.
.. list-table::
:widths: 60 20
:header-rows: 0
* - Number of files run
- 13
* - Tables in policyadmin
- 73
* - Records Added

* - schema_version
- 0900
4. Upgrade to Istanbul (0900) without any information in the migration schema
*****************************************************************************
Ensure you are on release 0800. (This may require running a downgrade before starting the test)
Drop db-migrator tables in migration schema:
.. code::
:number-lines:
DROP TABLE schema_versions;
DROP TABLE policyadmin_schema_changelog;
Modify db_migrator_policy_init.sh - remove any lines referencing downgrade and add the 2 lines under "Upgrade scripts".
Make/Redeploy to run upgrade.
.. list-table::
:widths: 60 20
:header-rows: 0
* - Number of files run
- 13
* - Tables in policyadmin
- 75
* - Records Added
- 13
* - schema_version
- 0900
5. Upgrade to Istanbul (0900) after failed downgrade
****************************************************
Ensure you are on release 0900.
Rename pdpstatistics table in policyadmin schema:
.. code::
RENAME TABLE pdpstatistics TO backup_pdpstatistics;
Modify db_migrator_policy_init.sh - remove any lines referencing upgrade and add the 2 lines under "Downgrade scripts"
Make/Redeploy to run downgrade
This should result in an error (last row in policyadmin_schema_changelog will have a success value of 0)
Rename backup_pdpstatistic table in policyadmin schema:
.. code::
RENAME TABLE backup_pdpstatistics TO pdpstatistics;
Modify db_migrator_policy_init.sh - Remove any lines referencing downgrade and add the 2 lines under "Upgrade scripts"
Make/Redeploy to run upgrade

Add timeStamp column to papdpstatistics_enginestats:
.. code::
ALTER TABLE jpapdpstatistics_enginestats ADD COLUMN timeStamp datetime DEFAULT NULL NULL AFTER UPTIME;
Modify db_migrator_policy_init.sh - remove any lines referencing upgrade and add the 2 lines under "Downgrade scripts"
Make/Redeploy to run downgrade
This should result in an error (last row in policyadmin_schema_changelog will have a success value of 0)
Remove timeStamp column from jpapdpstatistics_enginestats:
.. code::
ALTER TABLE jpapdpstatistics_enginestats DROP COLUMN timeStamp;
The config job will retry 5 times. If you make your fix before this limit is reached you won't need to redeploy.
Redeploy to run downgrade
