Adaptive Server® 15.5 Cluster Edition introduces multiple simultaneous failover, distributed transaction management, the mount and unmount commands, and the ability to use alter database to add space to an archived database.
Note: The Cluster Edition does not currently support in-memory databases, relaxed-durability databases, template databases, or minimally-logged DML.
Adaptive Server 15.5 Cluster Edition Feature and Platform Matrix
The feature and platform matrix shows feature availability for supported operating systems in Adaptive Server 15.5 Cluster Edition. A “Y” indicates the feature is supported for that platform.
Multiple simultaneous failover
Adaptive Server Cluster Edition version 15.5 and later support multiple simultaneous instance failures.
Adding space to an archive database
Adaptive Server Cluster Edition version 15.5 and later supports archive databases. In general, access to an archive database is the same in both a clustered and a nonclustered Adaptive Server. In either scenario, when an archive database runs out of space, use the alter database command to add space to the archive database.
