- NAME
- dbwr - Database Writer background process; writes new data
- to the database
-
-
- SYNOPSIS
- ddddbbbbwwwwrrrr
-
-
- DESCRIPTION
- The Database Writer or ddddbbbbwwwwrrrr 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, writes modified
- blocks from the database buffer cache to the database.
- Blocks are written in the proper order to maintain database
- integrity. The algorithm used assures that buffers are
- always available for writing. If additional buffers are
- needed, older buffers are written to the database first.
- The Database Writer does not need to write blocks when a
- transaction commits. The integrity of the data is
- guaranteed by the writing of committed data to the online
- redo log, rather than by writing to the database at commit
- time.
-
-
- FILES
- Writes data to database files.
