Installing Oracle Trace File Analyzer as root on Linux or Solaris on non-engineered systems automatically sets up and runs the Oracle ORAchk daemon.
The daemon restarts at 1 am every day to discover any environment changes. The daemon runs a full local Oracle ORAchk check at 2 am every day, and a partial run of the most impactful checks every 6 hours through the oratier1 profile.
The daemon automatically purges any collections older than 2 weeks.
If you install Oracle ORAchk in stand-alone mode, then run ./orachk -autostart to set up auto start. This is possible only when you run Oracle ORAchk as root on Linux or Solaris on non-engineered systems.
You can change the daemon settings after enabling auto start. To remove auto start any time, run ./orachk -autostop.
