There
are several restrictions that apply to cumulative dumps.
Although
you cannot perform cumulative dumps in a shared-disk cluster system, you can load a
cumulative dump that has been taken in a noncluster environment and load it into a
database in a shared-disk cluster.
You can have dump and load sequences that include a full database dump, cumulative dumps,
and transaction log dumps.
You can perform cumulative dumps on:
- In-memory databases (IMDBs) and reduced-durability databases (RDDBs) – since
load transaction requires full logging and ordered
logging, neither of which dump transaction performs on IMDBs
and RDDBs, using cumulative dumps lets you avoid these limitations
altogether.
- Databases with mixed log and data segments.
You cannot perform cumulative dumps on:
- The master database.
- Proxy databases.
- Temporary databases.
- (SAP ASE Cluster Edition) Shared-disk cluster environments –
however, you may load a cumulative dump from in a noncluster environment into a
shared-disk cluster.
You
cannot load cumulative dumps into an archive database, and doing so generates an error
message.
You cannot load cumulative dumps into a version of SAP ASE earlier than
15.7 SP100.
