创建和更新spfile时先删除或者备份共享目录上的spfile. 最好先不删除,如果删除它会把连接所在的目录删除掉,重建的时候会搞个DB_U

[Oracle@node1 pfile]$ export ORACLE_SID=MRAC1

SQL> alter session set nls_language=american;

先把原来的AMSCMD里的删除

SQL> create spfile='+DATA/MyRAC/spfileMYRAC.ora' from pfile;

File created.

SQL> startup

ORA-01565: error in identifying file '+DATA/MYRAC/spfileMYRAC.ora'

ORA-17503: ksfdopn:2 Failed to open file +DATA/MYRAC/spfileMYRAC.ora

ORA-01000: maximum open cursors exceeded

[oracle@node1 oracle]$ cat pfile_01.ora

*.SPFILE='+DATA/MYRAC/spfileMYRAC.ora'

删除SPFILE 重新创建并且修改语言到英文环境 SSH客户端没地方设置

SQL> create spfile='+data/myrac/spfileMYRAC.ora' from pfile='/opt/oracle/database/admin/MYRAC/pfile/myrac1_pfile.ora';

File created.

指定SPFILE目录和指定PFILE

结果节点2成功启动了SPFILE, 反而节点1的SPFILE 定位在本地目录上

SQL> startup nomount

ORACLE instance started.

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

spfile string /opt/oracle/database/product/1

0.2.0/db_1/dbs/spfileMYRAC1.or

经过几番折腾把本地SPFILE移走到其他目录下终于启动了共享磁盘上的SPFILE文件

[oracle@node1 dbs]$ mv spfileMYRAC1.ora /opt/oracle/database

[oracle@node1 dbs]$ exit

关闭先前的实例

SQL> shutdown immediate;

ORA-01507: database not mounted

ORACLE instance shut down.

启动内存模式

SQL> startup nomount

ORACLE instance started.

查看spfile路径发现正确用到了共享磁盘上的

SQL> show parameter pfile

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

spfile string +DATA/myrac/spfilemyrac.ora

加载控制文件

SQL> alter database mount

2 ;

Database altered.

打开数据库

SQL> alter database open;

Database altered.

查看是否归档

SQL> archive log list

Database log mode Archive Mode

Automatic archival Enabled

Archive destination +ARCHLOG

Oldest online log sequence 87

Next log sequence to archive 89

Current log sequence 89

节点1 交换日志

SQL> alter system switch logfile;

System altered

自动生成多级目录

ASMCMD> pwd

+archlog/myrac/archivelog/2012_09_27

ASMCMD> ls

thread_1_seq_88.256.795093263

thread_1_seq_89.257.795108837.

节点直接启动开启数据库模式

并且查看归档

节点2 交换下日志

SQL> alter system switch logfile;

ASMCMD> ls

thread_1_seq_88.256.795093263

thread_1_seq_89.257.795108837

thread_2_seq_47.258.795108927

注意事项

1 创建pfile和spfile 最好指定目录两边都要

2 创建和更新spfile时先删除或者备份共享目录上的spfile. 最好先不删除,如果删除它会把连接所在的目录删除掉,重建的时候会搞个DB_UNKONW 怪怪地.

3 注意共享磁盘上的spfile 结尾是不带数字的

4 归档文件路径只要指定一级目录就够了,它会自动创建多级目录的.

MySQL的角色：Web应用程序中的数据库Apr 17, 2025 am 12:23 AM

MySQL在Web应用中的主要作用是存储和管理数据。1.MySQL高效处理用户信息、产品目录和交易记录等数据。2.通过SQL查询，开发者能从数据库提取信息生成动态内容。3.MySQL基于客户端-服务器模型工作，确保查询速度可接受。

mysql：构建您的第一个数据库Apr 17, 2025 am 12:22 AM

构建MySQL数据库的步骤包括：1.创建数据库和表，2.插入数据，3.进行查询。首先，使用CREATEDATABASE和CREATETABLE语句创建数据库和表，然后用INSERTINTO语句插入数据，最后用SELECT语句查询数据。

MySQL：一种对数据存储的初学者友好方法Apr 17, 2025 am 12:21 AM

MySQL适合初学者，因为它易用且功能强大。1.MySQL是关系型数据库，使用SQL进行CRUD操作。2.安装简单，需配置root用户密码。3.使用INSERT、UPDATE、DELETE、SELECT进行数据操作。4.复杂查询可使用ORDERBY、WHERE和JOIN。5.调试需检查语法，使用EXPLAIN分析查询。6.优化建议包括使用索引、选择合适数据类型和良好编程习惯。

MySQL初学者友好吗？评估学习曲线Apr 17, 2025 am 12:19 AM

MySQL适合初学者，因为：1)易于安装和配置，2)有丰富的学习资源，3)SQL语法直观，4)工具支持强大。尽管如此，初学者需克服数据库设计、查询优化、安全管理和数据备份等挑战。
