To an application, Partitioned Files and FILESETs appear to be standard files. Although internal differences exist, for the most part these differences are not visible to the application.
Partitioned Files
Because a partition host file maintains a single partition member list at the system-file level, all connections access the same set of partition members. The fact that the partition host points to a list of partition member files is transparent to the application.
Most c-tree operations can be performed on the partition host.
File passwords are supported for partitioned files. A partition created on-the-fly is assigned the same security information as the host file.
Encryption is not supported with partitioned files.
Replication of the Partitioned File (and, therefore, its member files) is supported.
FILESETs
A FILESET appears to the application similar to a standard (non-partitioned) file. The only difference is that the FILESET is created on an ad hoc basis for a single connection. The FILESET host file points to a set of member files that is determined when the connection is made. The individual members of a FILESET are standard files.
Although appearing fairly standard, the FILESET has several limitations, such as being read-only. See Supported FILESET Features in FILESETs.
