affect other CDS servers or clerks.
— Monitor the success of skulks that originate at the server. A skulk is a method of
updating all replicas through repeated operations.
— Monitor the size and usage of the server’s clearinghouse and, if necessary,
discuss with the namespace administrator the need to relocate some replicas or
create a new clearinghouse.
— Monitor and tune system parameters that affect or are affected by CDS server
operation.
Note: When monitoring memory usage for CDS servers, it is important to
understand that memory remains allocated under certain conditions.
Memory associated with objects remains allocated until a skulk is
successfully completed. Memory associated with directories remains
allocated until the server is disabled and restarted.
For detailed discussions of these tasks, see Chapter 17 of the .
5.3.2 Managing CDS
CDS management tasks fall into the following two categories:
• Managing the namespace
— Oversee the creation of new directories and assign names according to a
standard, or enforce established guidelines in the assigning of names. (Beyond a
certain level in the directory hierarchy, you can delegate the responsibility of
creating and maintaining directories. You need to keep track of the new
directories being created to make sure they are appropriately replicated.)
— Determine the default access control policy.
— Administer and enforce the established access control policy for directories and
entries.
— Determine where and when new replicas of a directory are necessary.
— Create soft links for objects that change locations or for objects that need to be
renamed. An object is a resource, such as a disk, an application, or a node, that is
given a CDS name. A name plus its attributes make up an object entry.Asoft
link is a pointer that provides an alternate name for an object entry.
Publicize and encourage the use of the new names so that eventually the soft
links can be deleted.
— Solve or direct the resolution of problems involving multiple CDS servers.
• Managing CDS servers
— Manage access control on directories and objects, and monitor the size and usage
of directories in the server’s clearinghouse. Create new directories, possibly with
the namespace administrator, when necessary.
