HSQL Upgrade
This page details on how to upgrade existing HSQL database 1.8.1 to ensure a seamless transition to Harmony Suite 3.0.
Upgrade Rationale
To address potential security vulnerabilities, we have upgraded the HSQL library from version 1.8.1 to version 2.7.2.
As a result of this upgrade, customers will be able to set up and run batch jobs as usual after installing Harmony Suite 3.0.
However, it's important to note that existing Harmony databases cannot be used with the new HSQL 2.7.2 due to lack of support for older database versions. Therefore, upgrading the database structure is necessary.
Note:
Before proceeding with the HSQLDB database upgrade, please ensure the migration of all existing Harmony Suite Batch job roles from the current Harmony_Home/config/scrubbing folder to the latest 3.0 folder.
Rename the scrubbing_pdp.xml file located in the latest 3.0 installed folder at HARMONY_HOME/config/scrubbing to scrubbing_pdp.xml.orig.
Copy the existing scrubbing_pdp.xml file to the 3.0 HARMONY_HOME/config/scrubbing directory.
Upgrade Process for Windows:
Ensure the latest 3.0 HSQL database is not up and running.
Create a backup folder containing all the three Harmony 3.0 files: harmony.data, harmony.properties and harmony.script that's available in HARMONY_HOME/hsqldb folder.
Carry over existing database setups by copying the harmony.* files from previous HARMONY_HOME/hsqldb folder for e.g. 2.14 hsqldb folder into 3.0 hsqldb.
Open a command prompt.
Go to HARMONY_HOME, Execute the command upgradeDb.bat.
Follow the on-screen prompts to proceed with the database upgrade process. As indicated in the screenshot, press any key, such as "Enter," to continue with the upgrade.
Note : To exit, press Ctrl+C. The process will prompt the user to confirm if they wish to terminate the upgrade process.
Type 'N' to proceed with hsqldb database upgrade.
Type 'Y' to terminate the hsqldb database upgrade.
Once the upgrade process is complete.
At this point the hsqldb folder should contain the two files highlighted along with a backup folder for the old database files copied.
Execute runServerMode.bat.
When hsqldb server is started up the user should see the right version of HSQL i.e. 2.7.2.
After successful database upgrade, you can continue using Harmony Suite 3.0 with the upgraded database. Verify the integrity of the database and ensure that all data has been successfully migrated. Verify the batch job set ups and user profiles migrated.
Upgrade Process for Unix/Linux:
Ensure the latest 3.0 HSQL database is not up and running.
Carry over existing database setups by copying the harmony.* files from previous HARMONY_HOME/hsqldb folder for e.g. 2.14 hsqldb folder into 3.0 hsqldb.
Open a command prompt.
Go to HARMONY_HOME, Execute the command upgradeDb.sh
Once the upgrade process is complete.
At this point the hsqldb folder should contain the two files highlighted along with a backup folder for the old database files copied.
Execute runServerMode.sh.
When hsqldb server is started up the user should see the right version of HSQL i.e. 2.7.2.
After successful database upgrade, you can continue using Harmony Suite 3.0 with the upgraded database. Verify the integrity of the database and ensure that all data has been successfully migrated. Verify the batch job set ups and user profiles migrated.
