Migrating the Cell Directory Service from HP DCE 1.3.1

Installation of HP DCE 1.6 automatically attempts to preserve any CDS defined cached servers from previous configurations of HP DCE. However, if a newly migrated HP DCE 1.6 node returns warnings about being unable to locate a CDS server, it may be necessary to manually specify the server location with a dcecp cdscache create command.

To make full use of HP DCE 1.6 features, the directory version number of the root directory must be manually advanced to 4.0 after all CDS servers in the cell have been upgraded to HP DCE 1.6. (To determine the current directory version number, use the dcecp directory show /.: command, and look for the CDS_DirectoryVersion attribute.)

The procedure for doing this is discussed in "Managing CDS Directories - Upgrading the Directory Version on a Directory", in the OSF DCE Administration Guide - Core Components. This procedure makes use of the following dcecp commands:

dcecp> directory modify /.: -add {CDS_UpgradeTo 4.0}
dcecp> directory synchronize /.:
dcecp> clearinghouse verify /.:/<clearinghouse_name>
dcecp> directory synchronize /.:

Note that the dcecp clearinghouse verify command must be run for every clearinghouse in the cell, and must be run directly on the CDS server node hosting each clearinghouse. The command will not work from a remote node.
