GDUL产品特性

支持常见文件系统及ASM

1. 普通文件系统

11 11 11 FALSE 1.00 /u02/oradata/db11203/quest_sm01.dbf

2. ASM文件系统

GDUL> info
FILE# TS# RFILE# BIGFILE SIZE(GB) NAME
1 0 1 FALSE 1.09 +DATADG/a112a64/datafile/system.260.830974001
2 1 2 FALSE 1.60 +DATADG/a112a64/datafile/sysaux.265.830974001
3 2 3 FALSE 1.38 +DATADG/a112a64/datafile/undotbs1.264.830974001
4 4 4 FALSE 0.04 +DATADG/a112a64/datafile/users.263.830974001
5 6 5 FALSE 0.10 +DATADG/a112a64/datafile/user_admin

内置ASMCMD命令，能够直接读取ASM磁盘中的文件。
GDUL> asmcmd

Enter internal asmcmd.

ASMCMD> ls

DATADG/

ASMCMD> cd datadg
ASMCMD> cd a112a64
ASMCMD> cd datafile
ASMCMD> ls -l

3. 裸设备

GDUL除了支持UNIX下的裸设备外，还直接支持Linux下的裸设备(/dev/raw/raw#)，无需手工查找替换成裸设备下对应的分区或磁盘。

GDUL> info
FILE# TS# RFILE# BIGFILE SIZE(GB) NAME
1 0 1 FALSE 1.09 /dev/raw/raw1
2 1 2 FALSE 1.60 /dev/raw/raw2
3 2 3 FALSE 1.38 /dev/raw/raw3
4 4 4 FALSE 0.04 /dev/raw/raw4
