ONE Runtime Server 16.3.1 Upgrade Notes

Data source configuration now supports the monitorInterval attribute, which defines how often (in milliseconds) the server checks whether a data source connection is alive.

When not set, the interval defaults to dataSourceRefreshRate in the HealthStateProviders server component. Setting the value to zero or a negative number deactivates the check entirely.

Starting with Simba 2.6.38 and OSS 3.0.5, the JDBC Writer inserts records one at a time, causing slow writes. Ataccama ONE now automatically restores batched inserts for Simba 2.7.0+ and OSS 3.0.5+.

If you are using Simba 2.6.38–2.6.x, manually add ;EnableNativeParameterizedQuery=0 to your connection string.
