Projects / appctl


Appctl is a framework for virtually any server software. It provides a central script called "ctl" which allows you to start, stop, restart, maintain, or query the current status of an application. It is meant as a completely generic replacement for application-specific startup/stop scripts. The project also supplies generic monitoring scripts for clusters, which can dramatically decrease clustering costs.

Recent releases

  •  26 Jun 2009 16:42

    Release Notes: This release fixes a problem on Linux where multiple processes are running for a single handler.

    •  26 Jun 2009 16:41

      Release Notes: This release mainly brings new features. It adds extension points to hook your own extensions into the process of ctl in order to perform custom actions. The documentation has been updated accordingly.

      •  29 Apr 2007 14:57

        Release Notes: This release fixes the Linux status message printout where the PID was omitted from the printout. This does not affect the functionality at all; only the output text has been fixed.

        •  09 Feb 2007 00:28

          Release Notes: A PRIORITY variable has been added that allows definition of process priority. This parameter can be set in ctlenv (globally for all handlers), as well as handler-env files for a specific handler only.

          •  20 Dec 2006 21:15

            Release Notes: The recently introduced feature to allow custom PIDFILE location specification was not working properly when multiple handlers were specified in ctlenv. All PIDs were redirected to the PID file of the first handler, which caused messages about invalid PIDs for this handler. Since no PID files were written for other handlers, they were treated as handlers without PID files (PIDLESS_MODE). In most cases this was not creating any problems except for the ugly warnings about wrong PIDs.
