Resolved: Legacy Warehouse (Oracle) Connection Errors

Update 6/26/2025: The issue with access to the legacy Campus Data Warehouse (Oracle) has been resolved. You may now access the legacy system at https:csumb.edu/datawarehouse. Note: we continue to monitor daily loads in the legacy system after several days of data load failures. If you experience any problems with login to Oracle, please open an Optimize case.


Original issue:

When attempting to access the legacy Campus Data Warehouse (Oracle), users receive an ERR_CONNECTION_REFUSED message. This occurs both on campus (without VPN) and remotely when attempting to connect with the VPN.

Screenshot from legacy data warehouse (Oracle) showing ERR_CONNECTION_REFUSED error message.

Information Technology teams are working on the issue, which appears to be caused by a networking issue due to a hardware failure.
