Preserving a Clearinghouse Across a Server System Upgrade

If you plan to upgrade the operating system software on a CDS server system, and you want to preserve the clearinghouse (or clearinghouses) on the system, follow this procedure:

1. Make sure that you disable the clerk and server.

2. Before you perform the system upgrade, back up the following CDS files:

cds_attributes

cds_files

*_ch.checkpointnnnnnnnn

*_ch.tlognnnnnnnn

*_ch.version

cds_cache.nnnnnnnn

cds_cache.version

cds_cache.wan

(See OSF DCE Administration Guide - Introduction and the OSF DCE Testing Guide for the full pathnames of all CDS files.)

3. Perform the system upgrade.

4. Restore all the files that you backed up in step 2.

5. Follow the procedure described in Restarting Clerks and Servers for restarting a server. When the server process starts, it automatically locates the appropriate restored files and starts all clearinghouses on the system.
