Alert
AL00345 - PI OPC DA Server 2018 does not create a cached namespace file
2019-01-08
PI OPC DA Server normally creates a file during shutdown that contains information about the Server’s namespace. This is to facilitate faster startup. Since PI OPC DA Server 2018 does not create a namespace file, all startups will require a scan of the PI point database.

OSIsoft made significant improvements to the PI point database scan in the previous release (PI OPC DA Server 2017) so we expect the impact of this bug to be minimal. However, loading a PI OPC DA Server with more than 1.2 million PI points may cause unacceptable startup times. OSIsoft will release an update shortly to address this problem.
