◆Oracle用户的环境设置:
$ cat .profile
# Created for oracle RAC by ljg, 20091230 --- begin
#
umask 022
ORACLE_BASE=/u01/app/oracle;export ORACLE_BASE
CRS_HOME=/u01/crs/oracle/product/10/app;export CRS_HOME
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1;export ORACLE_HOME
ORACLE_SID=eoms1;export ORACLE_SID
AIXTHREAD_SCOPE=S;export AIXTHREAD_SCOPE
PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:$ORACLE_HOME/bin:$CRS_HOME/bin:.;export PATH
#
# Created for oracle RAC by ljg, 20091230 --- end
if [ -s "$MAIL" ] # This is at Shell startup. In normal
then echo "$MAILMSG" # operation, the Shell checks
fi # periodically.
◆oracleRAC操作语法(4个层次):
1、服务、实例、数据库:
srvctl status|start|stop service -d eoms -s TAF_EOMS_SERVER
srvctl status|start|stop instance -d eoms -i eoms1
srvctl status|start|stop database -d eoms
2、ASM实例:
srvctl status|start|stop asm -n sdwgrac1
3、nodeapps资源:
srvctl status|start|stop nodeapps -n sdwgrac1
4、crs:
crs_stat -t
crs_start res|-all
crs_stop res|-all
crsctl check|stop|start crs
/etc/init.crs start|stop
◆为ASM增加磁盘的操作步骤:
在盘阵侧为ASM新添加vdisk后,在两个节点执行以下步骤
cfgmgr:扫描硬件改动
lspv:检查是否有新盘
lsattr -El hdiskn:查看新加盘的属性
chdev -l hdiskn -a reserve_policy=no_reserve:把新加的盘设为共享
(如果有pvid,需要如下方式取消:chdev -l hdiskn -a pv=clear)
修改pv的属性为oracle用户使用:
chown oracle:dba /dev/rhdiskn
chmod 660 /dev/rhdiskn
最后在+ASM1实例添加磁盘:
$ export ORACLE_SID=+ASM1
$ sqlplus "/ as sysdba"
alter diskgroup DATA add disk '/dev/rhdiskn';
select group_number, name, TOTAL_MB, FREE_MB from V$asm_disk_stat;
alter diskgroup DATA drop disk DATA_0001;
◆创建表空间的步骤:
create (bigfile) tablespace test_ljg datafile '+DATA0/pm/datafile/test_ljg' size 200m;
alter database datafile '+DATA0/pm/datafile/test_ljg' resize 300m;
drop tablespace test_ljg including contents and datafiles;
