Re-sync OSM DB After Failure

Question

I extract highways from OSM every day from a cron job and keep a postgis database up-to-date. Due to a database change, the syncing has stopped in December 2017. I am trying to re-sync with a sequence number from earlier than December 03 2018 (when the syncing failed), but, I get a

org.openstreetmap.osmosis.core.OsmosisRuntimeException: The replication state doesn't contain a timestamp property.

Error. How can I rectify the issue and make the database current? Below is the failure:

Answer 1

In my case, The replication state doesn't contain a timestamp propertyresulted directly due to not using the https url in configuration.txt and it was not related to state.txt. Changing the url to baseUrl=https://planet.openstreetmap.org/replication/minute/ took care of the issue.

Java Run Time environment threw another issue because the security certificate related to https://planet.openstreetmap.org was not in JRE's keystore on the server from which I did the update. Resolved that by, downloading the security certificate from a browser and adding that to the JRE's keystore. Following is a useful post to resolve that issue.

Once both these problems are resolved, the process started to run as intended and completed successfully.
