- smon - System Monitor; performs instance recovery

- SYNOPSIS
- ssssmmmmoooonnnn
-

- DESCRIPTION
- The System Monitor or ssssmmmmoooonnnn background process, described in
- the _O_R_A_C_L_E _D_a_t_a_b_a_s_e _A_d_m_i_n_i_s_t_r_a_t_o_r'_s _G_u_i_d_e, is used to per-
- form instance recovery. It is used at instance startup and
- performs recovery for failed CPUs in shared disk systems.
- The ssssmmmmoooonnnn process is also responsible for cleaning up tem-
- porary segments that are no longer used, and for recovering
- dead transactions skipped during crash and instance recovery
- because of file-read or offline errors. It recovers these
- transactions when the tablespace or file is brought back
- online. The System Monitor process "wakes up" regularly to
- check whether it is needed, and can be called if another
- process needs it.
