I have a general question regarding redundancy and what is, and is not, synchronized between the pair of servers. One specific interest is in drivers and additional files that were loaded as a result of adding a driver such as DLL and JAR files such as with database drivers. If a newer version of a driver is added to the primary gateway are the files involved in that addition replicated to the backup server?
Add-on Modules are automatically added/updated on the backup server if the backup and master are synchronized when it happens on the master. If you have an outage and stuff is changed in the interim, you will have to make the backup match yourself.
I’m pretty sure it is the same for JDBC drivers, too.
I did confirm through experimentation that is does in fact copy the driver jar files as part of the synchronization.
