标签归档：dul

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

[oracle@xifenfei dul]$ ./dul
