Hi everyone,
I’d like to ask for insights or suggestions from the community regarding an issue we are facing after migrating to a new environment.
We are currently using SAS 9.4 (64‑bit) on Windows 11, and we frequently experience connection drops when accessing Google Cloud (extracting or loading data). The connection often fails after several minutes of processing, sometimes returning timeout messages or “connection reset by peer.”
This issue does not occur when performing the same workload on our previous setup:
SAS 9.4 (32‑bit) on Windows 10, where the connection was stable.
Environment
- SAS 9.4 (64‑bit)
- Windows 11
- Connecting to Google Cloud using the same connection method/driver we used on Windows 10 (likely ODBC-based)
Symptoms
- Frequent disconnections during long-running queries or data transfers
- Timeouts or intermittent "connection reset" errors
- Stable performance on the older 32‑bit Windows 10 environment
Questions for the community
- Has anyone experienced connection stability issues when using SAS 9.4 64‑bit on Windows 11 to access Google Cloud?
- Are there known compatibility considerations for Google Cloud ODBC connectors when moving from 32‑bit to 64‑bit SAS?
- Do we need a specific version of the Simba ODBC driver (or other Google Cloud–recommended drivers) for better stability on Windows 11/SAS 64‑bit?
- Are there recommended settings for:
- ODBC timeout
- Keep‑alive parameters
- Windows 11 network/TLS configuration
- SAS configuration that might affect long-running cloud connections?
Any experience, advice, or documentation references would be extremely helpful.
Happy to share logs or more details if needed.
Thanks in advance!
Heri
