set directory to new epoch(8cds)

Synopsis

cdscp set directory directory-name to new epoch master
clearinghouse-name [readonly clearinghouse-name...]
[exclude clearinghouse-name...]

Arguments

directory-name
The full name of the directory.

master clearinghouse-name
The full name of the clearinghouse in which an individual replica is located. The first clearinghouse-name specifies where the master replica is stored.

readonly clearinghouse-name ...
Designates the replicas in the specified clearinghouses as read-only.

exclude clearinghouse-name ...
Excludes the replicas in the specified clearinghouses.

Description
The set directory to new epoch command reconstructs a directory's replica set, allowing you to designate a new master replica or to exclude a replica. You must list each existing replica and indicate whether an existing replica needs to be included in or excluded from the new replica set. You can include or exclude more than one replica. The ellipses (...) indicates that you can specify multiple clearinghouse names, separated by spaces.

When you set a new epoch on a directory, you must disable the clearinghouse containing the replica that is being excluded. To do this, use the disable server command (if the server has more than one clearinghouse, all its clearinghouses will be disabled). Note that all clearinghouses that are not excluded must be enabled and available before you issue the disable server command.

Privileges Required
You must have A (Admin) permission to the directory, and the server principal needs A (Admin), r (read), and w (write) permission to the directory. When designating a new master replica, you also need w (write) permission to the clearinghouse that stores the new master replica, and the server principal needs w (write) permission to each clearinghouse where the replica type is changed to read-only.

Notes
This command may be replaced in future releases by the dcecp command, and may no longer be supported at that time.

Examples
The following command sets a new epoch for the directory /.:/mfg. The master replica is in the clearinghouse /.:/Paris1_CH, and read-only replicas are in the clearinghouses /.:/Chicago1_CH, /.:/Seattle_CH, and /.:/NY1_CH. The new replica set excludes the replica in the clearinghouse /.:/NY1_CH).

cdscp> set directory /.:/mfg to new epoch master /.:/Paris1_CH \
> readonly /.:/Chicago1_CH /.:/Seattle_CH exclude /.:/NY1_CH
