Organization of this subsection
(1) for HiRDB file system area "replica-HiRDB-file-system-area-name"
(2) server name server-name
(3) generation number generation-number
(4) reproduce "original-HiRDB-file-system-area-name"

(1) for HiRDB file system area "replica-HiRDB-file-system-area-name"

~<path name> ((1-165))

Specifies the absolute path name of the replica HiRDB file system area to be used for generation management.

Do not include a linefeed character inside the double quotation marks ("). Specify the replica HiRDB file system area name in such a manner that HiRDB-file-system-area-name + HiRDB-file-name become unique in the HiRDB system during the replica RDAREA definition.

(2) server name server-name

~<identifier> ((1-8))

Specifies the name of the back-end server that defines the replica HiRDB file system area.

An error results if the specified name is not for a back-end server. For a HiRDB single server configuration, do not specify this operand.

To register a generation for a shared RDAREA, specify the name of the updatable back-end server.

(3) generation number generation-number

~<unsigned integer> ((1-10))

Specifies the generation number to be used to manage the replica HiRDB file system area.

(4) reproduce "original-HiRDB-file-system-area-name"

~<path name> ((1-165))

Specifies the absolute path name of the original HiRDB file system area for which generations are to be managed.

Do not include a linefeed character inside the double quotation marks (").
