Type of data replicated in clusters
A high-availability cluster replicates data in dbspaces and sbspaces, but does not replicate data in blobspaces.
All built-in and extended data types are replicated to the secondary server. User-defined types (UDTs) must be logged and are located in a single database server. Data types with out-of-row data are replicated if the data is stored in an sbspace or in a different table on the same database server. For data stored in an sbspace to be replicated, the sbspace must be logged.
Data stored in operating system files or persistent external files or memory objects associated with user-defined routines are not replicated.
User-defined types, user-defined routines, and DataBlade modules have special installation and registration requirements. For instructions, see How data initially replicates.
