Notes on Cell Administration

Administering CDS

This section contains information on administering CDS that

supplements the information in the OSF DCE Administration

Guide —Core Services and OSF DCE Administration Reference.

Deleting a Clearinghouse

Before removing a CDS server clearinghouse, you must move or delete

any directories having master replicas in the clearinghouse. If you do not

do this, the clearinghouse removal operation fails, thereby preventing

unintended loss of data.

Appropriate administration commands for clearinghouses and

directories can be used to identify, move, or delete master replicas as

required, in order to remove a clearinghouse.

Skulking Directories

CDS propagates updated name space information among all directory

replicas with periodic automatic skulks so that consistent information is

available throughout the name space. To conserve network bandwidth,

these automatic skulks take place only every few hours.

Manual changes to the name space, such as the creation or deletion of

any name space object or directory, should always be followed by manual

skulks to immediately propagate these changes and additions. This will

avoid errors (such as entry not found) which can arise when clients

access directory replicas which have not yet received updates for recently

changed objects.

Note that skulks can take a few minutes to reach all parts of a cell, so do

not expect instant availability of updated information.
