[oracle@srcxtts response]$ cp netca.rsp ../netca.rsp^C
[oracle@srcxtts response]$ pwd
/home/oracle/database/response
[oracle@srcxtts response]$
2）更改拷贝的响应文件：
#-------------------------------------------------------------------- #以下参数不要更改 [GENERAL] RESPONSEFILE_VERSION = "11.2.0" OPERATION_TYPE = "createDatabase" #以下参数必须设置 [CREATEDATABASE] GDBNAME = "orcl" TEMPLATENAME = "General_Purpose.dbc" #以下参数不设置则使用默认值,建议设置 CHARACTERSET = "ZHS16GBK" TOTALMEMORY = "1024" #--------------------------------------------------------------------
3）静默建库：
$ $ORACLE_HOME/bin/dbca -silent -responseFile $DISTRIB/db_create.rsp Enter SYS user password: <输入sys用户密码> Enter SYSTEM user password: <输入system用户密码> Copying database files ... 37% complete Creating and starting Oracle instance ... 62% complete Completing Database Creation ... 100% complete Look at the log file "/u01/app/oracle/cfgtoollogs/dbca/ORCL/ORCL.log" for further details. 各参数含义如下: -silent 表示以静默方式安装 -responseFile 表示使用哪个响应文件,必需使用绝对路径 RESPONSEFILE_VERSION 响应文件模板的版本,该参数不要更改 OPERATION_TYPE 安装类型,该参数不要更改 GDBNAME 全局数据库名,点号前面默认是db_name,点号后面默认就是db_domain TEMPLATENAME 建库模板名,参考各模板定义:$ORACLE_HOME/assistants/dbca/templates/*.dbc CHARACTERSET 字符集,默认是WE8MSWIN1252 TOTALMEMORY 实例内存,默认是服务器物理内存的40%
4）建库后实例检查
ps -ef|grep ora_
5)建库后监听检查
lsnrctl status

6)启动实例
sql> startup
ORA-01078: failure in processing system parameters

文件不存在，直接根据模板init.ora拷贝一份
cp init.ora initorcl.ora
然后把里面相关路径改一下，此处主要把<ORACLE_BASE>换成/u01/app/oracle

再次启动：

7）启动到mount
sql> alter database mount;
alter database mount
*
ERROR at line 1:
ORA-01102: cannot mount database in EXCLUSIVE mode
解决办法：
网上找了一篇帖子，如下做的：
分析原因：
一、在HA系统中，已经有其他节点启动了实例，将双机共享的资源（如磁盘阵列上的裸设备）占用了；
二、说明Oracle被异常关闭时，有资源没有被释放，一般有以下几种可能，
1、Oracle的共享内存段或信号量没有被释放；
2、Oracle的后台进程（如SMON、PMON、DBWn等）没有被关闭；
3、用于锁内存的文件lk<sid>和sgadef<sid>.dbf文件没有被删除。
解决思路：
当发生1102错误时，可以按照以下流程检查、排错：
如果是HA系统，检查其他节点是否已经启动实例检查Oracle进程是否存在，如果存在则杀掉进程检查信号量是否存在，如果存在，则清除信号量检查共享内存段是否存在，如果存在，则清除共享内存段检查锁内存文件lk<sid>和sgadef<sid>.dbf是否存在，如果存在，则删除。具体做法：
首先，虽然我们的系统是HA系统，但是备节点的实例始终处在关闭状态，这点通过在备节点上查数据库状态可以证实。
其次、是因系统掉电引起数据库宕机的，系统在接电后被重启，因此我们排除了第二种可能种的1、2点。最可疑的就是第3点了。
查$ORACLE_HOME/dbs目录：
$ cd $ORACLE_HOME/dbs
$ ls sgadef*
sgadef* not found
$ ls lk*
/opt/oracle/product/ 10.2.0/db_1/dbs/lkSIMPLY
lkSIMPLY
$ rm lk*
删除后再次启动
sql> alter database mount ;
alter database mount
*
ERROR at line 1:
ORA-00205: error in identifying control file,check alert log for more info
错误变成找不到控制文件了，这好办，我们新库，还没有控制文件，这个后面在说。
然后按照上面那篇帖子：
https://blog.csdn.net/lzwgood/article/details/26368323
把oracle的共享内存清了：
查看共享内存段
[root@simply bdump]# ipcs -map
------ Shared Memory Creator/Last-op --------
shmidownercpidlpid
786444root64906438
819213root65496438
1409040 oracle3150216728
根据ID号清楚共享内存段
ipcrm –m1409040
我这里操作是没有成功的，不过执行了下面的操作就ok了！
查看信号量
[root@simply bdump]# ipcs -s
keysemidownerpermsnsems
0x17ff6454 360448oracle640154
清除oracle的信号量
[root@simply bdump]#ipcrm -s 360448
再次查询确认
[root@simply bdump]#ipcs -s
------ Semaphore Arrays --------
再查询共享内存段也ok了！
[root@simply bdump]# ipcs -m
再次启动的时候，又报了下面的错：
sql> startup
ORA-00845: MEMORY_TARGET not supported on this system
后来df -h发现/dev/shm总共930M，现在可用只有400多M，而memory_target设置的是900M。
memory_max_target big integer 900M
memory_target big integer 900M
考虑/dev/shm大小不够，增大之：
mount -t tmpfs shmfs -o size=2g /dev/shm
tmpfs /dev/shm tmpfs defaults,size=2g 0 0
全量重新挂载
mount -a
[oracle@srcxtts dbs]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_srcxtts-lv_root

/dev/sda1 477M 60M 392M 14% /boot
shmfs 2.0G 538M 1.5G 27% /dev/shm
再次重新启动到mount：
sql> alter database mount ;
alter database mount
*
ERROR at line 1:
ORA-00205: error in identifying control file,check alert log for more info
又回到控制文件的问题了，不要急，接着来。
截止到现在我们数据库用的还是pfile文件，要改成使用spfile文件：
sql> show parameter pfile
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
spfile string
sql> create spfile from pfile ;
File created.
sql> show parameter pfile

/u01/app/oracle/product/11.2.0

现在已经改成使用spfile文件了。
8）下面就来搞控制文件，oracle静默安装好后，默认给了个空文件在/u01/app/oracle/oradata/orcl/control01.ctl
拷贝两份到/u01/app/oracle/product/11.2.0.1/db_home1/dbs/control01.ctl,/u01/app/oracle/product/11.2.0.1/db_home1/dbs/control02.ctl
改初始化参数配置
sql> show parameter control

------------------------------------ ----------------------
VALUE
------------------------------
control_file_record_keep_time integer

control_files string
/u01/app/oracle/product/11.2.0

最后改完重启数据，然后就可以打开了。
