裸设备建库 1.首先查看要创建逻辑卷上的卷组datavg datavg ppsize 为32M [aix /] #lsvg datavg VOLUME GROUP: datavg VG IDENTIFIER: 00cd04ce00004c00000001215271137f VG STATE: active PP SIZE: 32 megabyte(s) VG PERMISSION: read/write TOTAL PPs: 2187 (69984 megabytes) MAX LVs: 256 FREE PPs: 625 (20000 megabytes) LVs: 17 USED PPs: 1562 (49984 megabytes) OPEN LVs: 15 QUORUM: 2 TOTAL PVs: 1 VG DESCRIPTORS: 2 STALE PVs: 0 STALE PPs: 0 ACTIVE PVs: 1 AUTO ON: yes MAX PPs per VG: 30480 MAX PPs per PV: 3048 MAX PVs: 10 LTG size (Dynamic): 256 kilobyte(s) AUTO SYNC: no HOT SPARE: no BB POLICY: relocatable 2.在datavg上建立好相应的裸设备 mklv -y‘ctl01‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 2 mklv -y‘ctl02‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 2 mklv -y‘ctl03‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 2 mklv -y‘redo01‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 2 mklv -y‘redo02‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 2 mklv -y‘redo03‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 2 mklv -y‘system01‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 19 mklv -y‘sysaux01‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 19 mklv -y‘users01‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 19 mklv -y‘undotbs01‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 19 mklv -y‘temp01‘ -w‘n‘ -s‘n‘ -r‘n‘ -t ‘raw‘ datavg 19 3.建好后赋予相应的属主及其权限 注：是r开头的设备 chown -R oracle:oinstall /dev/rctl0* chown -R oracle:oinstall /dev/rredo0* chown -R oracle:oinstall /dev/rsys* chown -R oracle:oinstall /dev/rundotbs01* chown -R oracle:oinstall /dev/rtemp01* chown -R oracle:oinstall /dev/rusers01* 查看复权后的结果 [aix94 /] #ls -al /dev/rctl0* crwxrwxr-x 1 oracle oinstall 45, 5 Jun 8 16:11 /dev/rctl01 crwxrwxr-x 1 oracle oinstall 45, 6 Jun 8 16:11 /dev/rctl02 crwxrwxr-x 1 oracle oinstall 45, 7 Jun 8 16:11 /dev/rctl03 [aix94 /] #ls -al /dev/rredo0* crwxrwxr-x 1 oracle oinstall 45, 8 Jun 8 22:00 /dev/rredo01 crwxrwxr-x 1 oracle oinstall 45, 10 Jun 8 16:14 /dev/rredo02 crwxrwxr-x 1 oracle oinstall 45, 11 Jun 8 22:00 /dev/rredo03 [aix94 /] #ls -al /dev/rsys* crw-rw---- 1 oracle oinstall 45, 13 Jun 8 22:00 /dev/rsysaux01 crw-rw---- 1 oracle oinstall 45, 12 Jun 8 16:11 /dev/rsystem01 [aix94 /] #ls -al /dev/rusers01 crw-rw---- 1 oracle oinstall 45, 14 Jun 8 16:11 /dev/rusers01 [aix94 /] #ls -al /dev/rtemp01 crw-rw---- 1 oracle oinstall 45, 16 Jun 8 16:12 /dev/rtemp01 [aix94 /] #ls -al /dev/rundotbs01 crw-rw---- 1 oracle oinstall 45, 15 Jun 8 16:11 /dev/rundotbs01 [aix94 /] #lsvg -l datavg TYPE均为RAW设备类 datavg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT ctl01 raw 2 2 1 open/syncd N/A ctl02 raw 2 2 1 open/syncd N/A ctl03 raw 2 2 1 open/syncd N/A redo01 raw 2 2 1 open/syncd N/A redo02 raw 2 2 1 open/syncd N/A redo03 raw 2 2 1 open/syncd N/A system01 raw 19 19 1 open/syncd N/A sysaux01 raw 19 19 1 open/syncd N/A users01 raw 19 19 1 open/syncd N/A undotbs01 raw 19 19 1 open/syncd N/A temp01 raw 19 19 1 open/syncd N/A [aix94 /] #su -oracle 添加裸设备mapping文件 oracle$ vi raw.txt 添加以下内容 system=/dev/rsystem01 undotbs1=/dev/rundotbs01 redo1_1=/dev/rredo01 redo1_2=/dev/rredo02 redo1_3=/dev/rredo03 control1=/dev/rctl01 control2=/dev/rctl02 control3=/dev/rctl03 users=/dev/rusers01 temp=/dev/rtemp01 sysaux=/dev/rsysaux01 bash-3.2$ more .profile 添加 DBCA_RAW_CONFIG=/u01/oracle/product/10.2.0/db_2/dbs/raw.txt export DBCA_RAW_CONFIG 完成就就可以DBCA创建数据库了
