umestored

Description

Persistent Store and Queue services are provided by umestored. A store configuration file is required.

The DTD used to validate a configuration file will be dumped to standard output with the -d or --dump-dtd. After dumping the DTD, umestored exits instead of providing persistence services as usual.

The configuration file will be validated against the DTD if either the -v or --validate options are given. After attempting validation, umestored exits instead of providing persistence services as usual. The exit status will be 0 for a configuration file validated by the DTD and non-zero otherwise.

Umestored normally remains attached to the controlling terminal and runs until interrupted. If the -f or --detach options are given, umestored instead forks, detaches the child from the controlling terminal, and the parent exits immediately.

Command line help is available with -h.

Usage Notes

When shutting down the UM Persistent Store or Queue daemon, use a SIGINT to trigger a clean shutdown, which attempts to cleanly finish outstanding IO requests before shutting down. Two successive SIGINTs force an immediate shutdown.

Exit Status

The exit status from umestored is 0 for success and some non-zero value for failure.
