In this hostile society, are you still worried about the server being attacked? Still worried about the server being killed? Tell you to use the South Korea KA High-protection server, no longer worry about the server was killed. Korea KA server can provide a single anti-100G (100G udp+10g TCP), more than a shield million gigabit NP enterprise-class hardware firewall cluster, single-machine commitment to 10g/30g hard defense, beyond the defensive automatic shielding IP, attack the past immediatel
Does oracle, a data file with the same and relative file numbers in different tablespaces, distinguish them? To solve this problem, oracle adds the DATA_OBJECT_ID information on the basis of the original 6 byte rowid to form the extended rowid, which consists of four parts: data_object_id, rfn, block #, row #. Through the combination of data_object_id and data dictionary view, oracle can quickly convert rfn to file_id, so as to accurately locate rows.

one-to-one equal. Otherwise, when the number of data files does not exceed 1022, the oracle database should try to keep file_id and relative_fno the same, after more than 1022 data files exist, oracle will ensure that the file_id is unique throughout the database, and relative_fno is unique in a single tablespace.
Then there will be a problem. How Does oracle, a data file with the same and relative file numbers in different tablespaces, distinguish them? To solve this problem, oracle adds the D
