### 以此注释后面的内容在系统shell中运行 --- 以此注释后面的内容在Sqlplus中运行 ### 1、取得oracle用户的环境 su - o

### 以此注释后面的内容在系统shell中运行  
--- 以此注释后面的内容在Sqlplus中运行  
 
### 1、取得Oracle用户的环境  
su - oracle  
cd /oracle  
source .cshrc  
### 显示当前Oracle10gRAC/crs运行情况  
crs_stat -t  
 
### 2、关闭Oracle,注意 dbser1 为AIX主机名称  
### 连接 Oracle  
sqlplus /nolog  
conn /as sysdba  
--- 关闭实例  
shutdown immediate  
input "press to continue..." 
exit  
 
### 3、关闭节点  
srvctl stop nodeapps -n dbser1  
crs_stat -t  
exit  
### 关闭crs  
/etc/init.crs stop  
### 完成关闭  
 
--- 4、在sqlplus中启动或关闭实例  
--- 关闭实例  
shutdown immediate;  
--- 启动实例  
startup;  
 
--- 5、调整SGA,需重新启动  
alter system set sga_max_size=4000M scope=spfile;  
alter system set sga_target=4000M scope=spfile;  
--- 重启实例完成参数应用  
--- 关闭实例  
shutdown immediate;  
--- 启动实例  
startup;  
 
--- 6、等上一步骤完成重启后,分配缓存和池的大小  
alter system set shared_pool_size=1048M scope=spfile;  
alter system set db_cache_size=1024M scope=spfile;  
alter system set large_pool_size=208M scope=spfile;  
alter system set java_pool_size=112M scope=spfile;  
--- 重启实例完成参数应用  
--- 关闭实例  
shutdown immediate;  
--- 启动实例  
startup;  
 
--- 7、显示缓存和池的大小  
show parameter sga_max_size;  
show parameter sga_target;  
show parameter db_cache_size;   
show parameter shared_pool_size;   
show parameter large_pool_size;  
show parameter java_pool_size;  
show parameter pga_aggregate_target;  
 
--- 8、关于Oralce的配置文件修改的问题  
--- 从当前配置spfile创建pfile文本文件/oracle/10.2/db_1/dbs/NARICOM.ora  
create pfile='/oracle/10.2/db_1/dbs/NARICOM.ora' from spfile;  
--- 实例处于关闭时,可恢复系统配置  
--- 从pfile(文本)文件/oracle/10.2/db_1/dbs/NARICOM.ora创建系统配置spfile(二进制)文件   
create spfile from pfile='/oracle/10.2/db_1/dbs/NARICOM.ora';  
 
### 9、启动Oracle/crs,root用户下,自动启动本机实例  
/oracle/10.2/crs/bin/crsctl start crs  
 
--- 10、更改转换字符集为GBK  
shutdown immediate;  
startup mount;  
alter system enable restricted session ;  
alter system set JOB_QUEUE_PROCESSES=0;  
alter system set AQ_TM_PROCESSES=0;  
alter database open;  
--- 当处于集群时,需要将pfile中 cluster_database改为false到spfile启动Exclusive模式  
ALTER DATABASE character set INTERNAL_USE ZHS16GBK;  
shutdown immediate;  
startup;  
select name,value$ from props$ where name like '%NLS%';  
 
### 11、集群信息查看操作  
lsvg –l datavg
