21.5 Deleting a Clearinghouse
You may need to delete a clearinghouse from the server system on which it resides
when
• The system is scheduled for reallocation or removal from your network.
• You no longer want the system to function as a CDS server.
21.5.1 Before You Delete a Clearinghouse
Before you attempt to delete a clearinghouse, make sure of the following:
• The clearinghouse is known to the server.
• The clearinghouse does not store a master replica.
When you clear a clearinghouse, the server on which the clearinghouse was running no
longer has information about the clearinghouse in its internal memory. If you
subsequently try to delete the clearinghouse, CDS will not find it and will return a
message that it does not exist. Before you can delete a cleared clearinghouse, you must
recreate it using the clearinghouse create command.
CDS does not allow you to delete a clearinghouse that contains a directory’s master
replica. Before you delete such a clearinghouse, you must designate another replica in
that directory’s replica set as the master replica. If no other replicas of the directory
exist, create a read-only replica at another clearinghouse and then designate it as the
directory’s new master replica before you delete the original master replica from the
clearinghouse. (See Section 21.2 for instructions on modifying a directory’s replica
set.)
21.5.2 Permissions for Deleting a Clearinghouse
The following permissions are required for deleting a clearinghouse:
• You need write and delete permissions to the clearinghouse, and administer
permission to all of the directories that store replicas in the clearinghouse.
• The server principal needs delete permission to the associated clearinghouse object
entry, and administer permission to all directories that store replicas in the
clearinghouse.
