Officially, the answer to the this question is no. The following is from the System Requirements page for ALM found at https://admhelp.microfocus.com/alm/specs/alm-qc-system-requirements.htm#ALM1220
**All database servers, unless otherwise stated, have been validated on 64 bit configurations**
**Micro Focus ALM is certified to work with Enterprise and Standard editions of Microsoft and Oracle databases**
Now that being said you could probably use the Developer Edition if you disable database validations and either re-install ALM or re-run the configuration wizard on the server. See the Installation and Upgrade Guide page 154 for more information on this.
Disabling Validation Checks for the Installation Wizard
The ALM Installation Wizard automatically performs validation checks to verify that particular system configurations requirements are met. If the ALM configuration does not complete due to a failed validation, you can fix the problem or disable selected validation checks, and rerun the installation.
**You should disable validation checks only if you decide to take responsibility for the ALM server
In my opinion I would not use the Developer Edition if at all possible, it has not been tested with the software and could cause unpredictable results.
