dmctlcvt工具可以实现控制文件和文本文件之间的转换

下面例子是控制文件转换为文本文件：

[dmdba@dem test]$ file dm.ctl
dm.ctl: data

[dmdba@dem test]$  strings dm.ctl
test
SYSTEM
/home/dmdba/dmdbms/data/test/SYSTEM.DBF
ROLL
/home/dmdba/dmdbms/data/test/ROLL.DBF
RLOG
/home/dmdba/dmdbms/data/log01.log
/home/dmdba/dmdbms/data/log02.log
/home/dmdba/dmdbms/data/log03.log

/home/dmdba/dmdbms/data/test/BOOKSHOP.DBF
DMHR
NORMAL
/home/dmdba/dmdbms/data/test/DMHR.DBF
HMAIN"
/home/dmdba/dmdbms/data/test/HMAIN

[dmdba@dem test]$ which dmctlcvt
~/dmdbms/bin/dmctlcvt

[dmdba@dem test]$ dmctlcvt help
DMCTLCVT V8

格式: ./dmctlcvt KEYWORD=value
注意: 控制文件名称必须指定为dm.ctl、dmmpp.ctl、dss.ctl

关键字              说明
--------------------------------------------------------------------------------
TYPE                1 转换控制文件为文本文件（源文件路径中控制文件名称必须是dm.ctl或dmmpp.ctl或dss.ctl）
                    2 转换文本文件为控制文件（目标文件路径中控制文件名称必须是dm.ctl或dmmpp.ctl或dss.ctl）
SRC                 源文件路径
DEST                目标文件路径
DCR_INI             dmdcr.ini文件路径
DFS_INI             dmdfs.ini文件路径
HELP                打印帮助信息

示例：
./dmctlcvt TYPE=1 SRC=/opt/dmdbms/data/dameng/dm.ctl DEST=/opt/dmdbms/data/dameng/dmctl.txt
./dmctlcvt TYPE=2 SRC=/opt/dmdbms/data/dameng/dmctl.txt DEST=/opt/dmdbms/data/dameng/dm.ctl

[dmdba@dem test]$ dmctlcvt type=1 src=dm.ctl dest=dmctl.text
DMCTLCVT V8
convert ctl to txt success!

[dmdba@dem test]$ dmctlcvt type=1 src=dm.ctl dest=dmctl.text
DMCTLCVT V8
convert ctl to txt success!
[dmdba@dem test]$ cat dmctl.text
