ID: 15848 Title: <tt>mk_oracle</tt>: Fix asynchronous execution on <tt>systemd</tt> systems and direct call from the command line Component: Checks & agents Level: 1 Class: Bug fix Version: 2.3.0b1 On <tt>systemd</tt> systems, the Oracle agent plugin did not properly execute any asynchronous SQL queries (see also <a href="https://checkmk.com/werk/13732">werk #13732</a>). Furthermore, when being called directly from the command line without any options, the plugin incorrectly reported `Unhandled location` and terminated, even if it was located under <tt>..check_mk_agent/plugins/</tt>.
