configureTenantAccess

public void configureTenantAccess(Connection connection)
                           throws FHIRPersistenceDBConnectException

Find the tenantKey for the datasource/tenant from the FHIR server configuration and use it to set up the connection for access by this tenant by setting the SV_TENANT_ID session variable (via the FHIR_ADMIN.SET_TENANT stored procedure). Note that the database user we connect as does not have direct access to WRITE to the SV_TENANT_ID...it can only be set through the SET_TENANT call, for which we have been explicitly granted execute privilege.

Parameters:

connection - the connection to configure

Throws:

FHIRPersistenceException - if the configuration fails

FHIRPersistenceDBConnectException
