Replication Server supports as the replicate database:
In-memory databases
Relaxed-durability databases set with durability at no_recovery
The primary database must be a traditional full durability disk-resident database. For convenience, this document refers to relaxed-durability databases with durability set to non_recovery as “relaxed-durability databases.”
You can initialize an in-memory and relaxed-durability database as a new replicate database by obtaining data, object schema, and configuration information from one of:
A template database that retains basic information. See “Using a template database to initialize in-memory and relaxed-durability databases”.
A database dump from another database and then load the dump to the target in-memory database or relaxed-durability database. See “Using a dump from another database to initialize in-memory and relaxed-durability databases”.
The dump source database can be another in-memory database, relaxed durability database, or a traditional disk-resident database.
In-memory and relaxed-durability databases loose their object definition, data, and RepAgent configuration once the host data server shuts down or restarts. You must reinitialize the in-memory or relaxed durability database from the template or database dump from a source database.
