这几天朋友问我dul怎么用,抽时间给他做了个实验。其实网上已经有很多dul的使用方法,而且我也不推荐使用dul、odu这样的工具去恢复数据,这是体力活的. 而且现在最新版都是时间限制,好像是40多天,具体的忘记了。希望大家不要用到此种类似的工具 dul主要的
这几天朋友问我dul怎么用,抽时间给他做了个实验。其实网上已经有很多dul的使用方法,而且我也不推荐使用dul、odu这样的工具去恢复数据,这是体力活的.
而且现在最新版都是时间限制,好像是40多天,具体的忘记了。希望大家不要用到此种类似的工具
dul主要的参数文件为init.dul 下面是个例子
╭─oracle@enmotech ~/dul ╰─? cat init.dul osd_big_endian_flag=false --小字节平台 osd_dba_file_bits=10 osd_c_struct_alignment=32 osd_file_leader_size=1 osd_word_size = 32 #osd这些参数涉及到主机平台的 feedback = 1000 dc_columns=2000000 dc_tables=10000 dc_objects=1000000 dc_users=400 dc_segments=100000 USE_LOB_FILES =TRUE CONTROL_FILE = file.txt --指定了要抽出的文件信息 LDR_ENCLOSE_CHAR=| db_block_size=8192 export_mode=FALSE --使用文件格式导出文件,true导出dmp文件 compatible=11
dul第二个主要文件是CONTROL_FILE参数指定的文件,. 下面是个例子
╭─oracle@enmotech ~/dul ╰─? cat file.txt 0 1 /oradata/orcl/system01.dbf 1 2 /oradata/orcl/sysaux01.dbf 2 3 /oradata/orcl/undotbs01.dbf 4 4 /oradata/orcl/users01.dbf 30 5 /oradata/orcl/test01.dbf 28 6 /oradata/orcl/dbtk.dbf 29 7 /oradata/orcl/ignite.dbf 5 8 /oradata/orcl/goldengate01.dbf 31 9 /oradata/orcl/ogg_test01.dbf 33 1024 /oradata/orcl/big_test.dbf ╭─oracle@enmotech ~/dul 这里也可以直接写文件名 ╭─oracle@enmotech ~/dul ╰─? cat file.txt 1 ? /oradata/orcl/system01.dbf /oradata/orcl/sysaux01.dbf /oradata/orcl/undotbs01.dbf /oradata/orcl/users01.dbf /oradata/orcl/test01.dbf /oradata/orcl/dbtk.dbf /oradata/orcl/ignite.dbf /oradata/orcl/goldengate01.dbf /oradata/orcl/ogg_test01.dbf /oradata/orcl/big_test.dbf ╭─oracle@enmotech ~/dul ╰─?
下面开始使用,实在system文件存在的前提下
