OMF file structure

OMF file structure SQL> show parameter db_create_file_destNAME TYPE VALUE =--------------------------- mongodb_create_file_dest string D: \ oradataSQL> CREATE TABLESPACE tbs_2; The TABLESPACE has been created. Theoretically, the data file of tbs_2 should be created under d: \ oradata, but in fact it is not under db_create_file_dest but under d: \ oradata \ max \ datafile. Why? Later I found out that I forgot omf's file management structure, such as db_create_file_dest =/u01/oradata/u01/oradata/SAMPLE --------------- database name/datafile -------------- file category/Category _. dbf/o1_mf_sysaux_cmr7t88p _. dbf/o1_mf_sys_undo_2ixfh90q _. dbf/o1_mf_dflttmp_157se6ff _. tmp/logfile/controlfile should be more careful when reading the document next time.
