We've just covered basic commands, but there are many more aspects to discuss concerning the implementation, and some of these have an important performance impact.
A container in this type of table space can be defined as a regular OS file or can be defined as a raw partition.
We do not recommend the use of raw partitions, since this adds complexity in disk and space management. A well-tuned DMS table space, that has containers defined as data files, will perform as well as containers defined as raw partitions.
Space is preallocated in the DMS table space. When multiple containers are defined, they are filled in round-robin fashion, one extent in each container. When autoresize is used, the containers will grow automatically, until maxsize value is reached, or until the filesystem is full, whichever comes first.
