HA-Tools

The HA-Tools provide some programs to improve shell scripting, especially in a High Availability environment. The halockrun program provides a simple and reliable way to implement locking in shell scripts (a typical usage for halockrun is to prevent cronjobs to run simultanously), and the hatimerun program provides a time-out mechanism.

          •  03 May 2009 10:58

            Release Notes: The portability of halockrun was improved by fixing a bug in the non-blocking mode (-n) and introducing the noop-mode (-N) as an alternative to -t for systems which don't implement the GETLK operation. Error reporting was improved in async mode in case the command can't be executed at all. Convenience was improved by allowing hh:mm:ss notation for timeout values with hatimerun.
