Tablespace names beginning with o1_mf and ending with cb58lw2z_.dbf?

2932017Feb 9 2016 — edited Feb 9 2016

Hello all,

I can't figgure out where in the database creation process how all the tablespaces are being named beginng for example with o1_mf and ending with cb58lw2z_.dbf:

DB_1> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/u01/shared_data/oradata/DB/datafile/o1_mf_system_cb58lw2z_.dbf
/u01/shared_data/oradata/DB/datafile/o1_mf_undotbs3_cb58q00g_.dbf
/u01/shared_data/oradata/DB/datafile/o1_mf_sysaux_cb58krqh_.dbf
/u01/shared_data/oradata/DB/datafile/o1_mf_undotbs1_cb58nbnn_.dbf
/u01/shared_data/oradata/DB/datafile/o1_mf_undotbs2_cb58pznk_.dbf
.
.
.
/u01/shared_data/oradata/DB/datafile/o1_mf_index_cb58pznk_.dbf

Not that it is a big deal, I would like to know how this is happening.  Example how I am creating a tablespace:

CREATE bigfile TABLESPACE "INDEXES" LOGGING datafile SIZE 100M AUTOEXTEND ON NEXT 250M MAXSIZE UNLIMITED EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;

DB_1> select * from v$version;
