ChkptCache - checkpoint the Vesta-2 cache server


ChkptCache [ -n ]


ChkptCache invokes the Checkpoint method of the Vesta-2 cache server named in the user's Vesta-2 configuration file.

By default, ChkptCache flushes the cache server's logs to disk, and writes a root node to the graph log with a package version fingerprint equal to the fingerprint of the empty string, a model number of zero, an empty list of children, and a done value of false.

If -n is specified, the name and port number of the cache that would be checkpointed is printed, but no action is taken.

Configuration Variables

Like most Vesta-2 applications, ChkptCache reads site-specific configuration information from a Vesta-2 configuration file named vesta.cfg. The program first looks for this file in the current directory; if none is found there, it looks in your home directory.

The configuration file is divided into a number of sections, denoted in the file by [SectionName]. The variables used by ChkptCache are in the section denoted by [CacheServer]. Here are the variables and their meanings; the types of the variables are shown in parentheses.

Host (string)
The hostname of the machine on which the cache server is running.

Port (integer)
The port number on host named by Host to contact. This allows multiple cache servers to be running on the same machine; each one listens on a different port for connections.
