Using the CDS Subtree Commands to Restructure CDS Directories
20.4.2 Performing a Merge Operation into a Foreign Cell
To merge CDS data into the namespace of a foreign cell, follow these steps:
1. While logged into a privileged account (cell_admin or a member of cds-admin
group) on the target machine in the foreign cell, run the directory merge
command to merge the contents of the source cell’s directory with an existing
directory.
2. If you intend to continue accessing the merged information from the source cell,
delete the uppermost directory in the source subtree and replace the deleted
information with a single soft link of the same name as that directory. This
redirects lookups of the information to its new location in the foreign cell.
20.5 Restoring Merged CDS Directories
You can use the dcecp link delete and directory merge commands to restore deleted
directories and their contents to your namespace.
First run the link delete command to remove the soft links in the former source location,
then use the directory merge command to append the copy of the directory back under
its former parent directory.
If the directory has slave replicas, use the directory create command to create a new
replica of the directory in each of the clearinghouses from which the directory was
deleted.
Remember that the directory merge command affects only directories and their
contents. It does not copy clearinghouses or their associated clearinghouse object
entries and therefore cannot be used to restore clearinghouses or to account for
discrepancies in information among individual replicas resident on different
clearinghouses. Furthermore, the directory information in a particular location may
have changed since the time of the original merge operation.
