Hitz Proxy Server Setup Info

last updated 4/22/99

The Cadence Locking Daemon process (cdsd) maintains file locking info in order to prevent file-sharing problems.  This process generally runs on the machine where the file system resides, but our NFS fileserver Hitz is not actually a workstation.   We have to configure a "proxy server" for Hitz in order for Cadence to run on the BWRC cluster.  This was done with the following steps:

1. Create the directory /tools/cds99/IC443/tools/dfII/etc/license/
2. Create the file proxy which contains the following line:

hitz joy hitz_proxy

Where "hitz" is the name of the file server as it appears in the /etc/mnttab file, "joy" is the name of the machine where the cdsd process will run, and "hitz_proxy" is the prefix that will appear at the front of joy's lock table entries.

Past Problems

We encountered problems in the past because the "hitz" entry in the /etc/mnttab file was inconsistent across the network.  It was "hitz" on some machines and "hitz.eecs.berkeley.edu" on others.  For this scheme to work, the entry in the "proxy" file must be exactly as written in /etc/mnttab.
