I have upgrade ArcGIS Enterprise form 10.5 to 10.5.1 following the established steps in the documentation (Upgrade Portal for ArcGIS—Portal for ArcGIS (10.5.x) | ArcGIS Enterprise). However, after upgrading the data store, I am unable to validate the server and in the server administrator, the tile cache data store is validated, but not the managed database (i.e. relational).
In Portal when I go to Org > Edit Setting > Servers, the hosting server does not validate and I get this error:
ArcGIS Server administration URL 'https://lib-gis-server.library.illinois.edu/arcgis' is accessible. Validating hosting server. ArcGIS Server 'https://lib-gis-server.library.illinois.edu/arcgis' version matches with Portal for ArcGIS. Error: Failed to validate the server managed database '/enterpriseDatabases/AGSDataStore_ds_qcne02dh'.
I have investigated logs on the windows server machine and the PostgreSQL gets a rapid shutdown command and provides no error codes (the code ID is '0' severity error).
What is also weird, though, is that all feature, image, and scene services currently seem to be working properly.
NOTE: We have also recently updated our licensing and this could be an issue. We are actively investigating that, but we are unsure at this time.
