最近测试了下dul,整体感觉和odu差不多
1.配置init.dul
[oracle@xifenfei dul]$ more init.dul osd_big_endian_flag=false osd_dba_file_bits=10 osd_c_struct_alignment=32 osd_file_leader_size=1 osd_word_size = 32 dc_columns=2000000 dc_tables=10000 dc_objects=1000000 dc_users=400 dc_segments=100000 Buffer=10485760 control_file = control.txt db_block_size=8192 export_mode=true --false表示是sqlloader,true表示imp compatible=10
2.配置控制文件
[oracle@xifenfei dul]$ more control.txt
0 1 /u01/oracle/oradata/XFF/system01.dbf
1 2 /u01/oracle/oradata/XFF/undotbs01.dbf
2 3 /u01/oracle/oradata/XFF/sysaux01.dbf
4 4 /u01/oracle/oradata/XFF/users01.dbf
6 5 /u01/oracle/oradata/XFF/datfttuser.dbf
--sql语句
select ts#,rfile#,name from v$datafile;
3.启动dul
