一、环境介绍:
我在db01和db02两台Linux虚拟机上首先分别安装了一套数据库软件，，在db01主机上创建了名为woo的数据库；我们这次的实验是要搭建了一套Oracle 11g Active DataGuard；目的是为了实现数据库同步的功能，并且了解Oracle 11g DG的基本功能。

二、11g ADG部署：
1、pri端和sty端配置静态监听
[oracle@sty admin]$ cat listener.ora
# listener.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = Woo )
(ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
)
)
[oracle@sty admin]$cat tnsname.ora
# tnsnames.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
STY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.51)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = woo)
)
)
PRI =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.50)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = woo)
)
)
2、修改primary端初始化参数文件
startup mount;
alter database archivelog;
alter database force logging;
alter database open;
alter system set log_archive_config = 'DG_CONFIG=(pri,sty)' scope=spfile;
alter system set log_archive_dest_1 = 'LOCATION=/DBBackup/Archive VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=pri' scope=spfile;
alter system set log_archive_dest_2 = 'SERVICE=sty LGWR SYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=sty' scope=spfile;
alter system set log_archive_dest_state_1 = ENABLE;
alter system set log_archive_dest_state_2 = ENABLE;
alter system set fal_server=sty scope=spfile;
alter system set fal_client=pri scope=spfile;
alter system set standby_file_management=AUTO scope=spfile;
3、在primary端pfile参数文件和密码文件，并且拷贝到standby段相应位置
SQL> create pfile from spfile;
File created.
[oracle@db01 dbs]$ scp initwoo.ora orapwwoo db02:/DBSoft/oracle/product/11.2.4/dbhome_1/dbs
oracle@192.168.1.51's password:
initwoo.ora 100% 1260 1.2KB/s 00:00
orapwwoo 100% 1536 1.5KB/s 00:00
[oracle@db01 oracle]$ scp -r admin/ diag/ fast_recovery_area/ oradata/ 192.168.1.51:$ORACLE_BASE
oracle@192.168.1.51's password:
init.ora.512201522543 100% 1778 1.7KB/s 00:01
dp.log 100% 116 0.1KB/s 00:00
........
4、修改standby端的监听文件及初始化参数文件
--修改监听文件
[oracle@db02 ~]$ cd $ORACLE_HOME/network/admin
[oracle@db02 admin]$ vi listener.ora
# listener.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = db02)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = woo)
(ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
(SID_NAME = woo)
)
)
ADR_BASE_LISTENER = /DBSoft/oracle
--启动监听

与MySQL中使用索引相比，全表扫描何时可以更快？
Apr 09, 2025 am 12:05 AM
全表扫描在MySQL中可能比使用索引更快，具体情况包括：1)数据量较小时；2)查询返回大量数据时；3)索引列不具备高选择性时；4)复杂查询时。通过分析查询计划、优化索引、避免过度索引和定期维护表，可以在实际应用中做出最优选择。
可以在 Windows 7 上安装 mysql 吗
Apr 08, 2025 pm 03:21 PM
是的，可以在 Windows 7 上安装 MySQL，虽然微软已停止支持 Windows 7，但 MySQL 仍兼容它。不过，安装过程中需要注意以下几点：下载适用于 Windows 的 MySQL 安装程序。选择合适的 MySQL 版本（社区版或企业版）。安装过程中选择适当的安装目录和字符集。设置 root 用户密码，并妥善保管。连接数据库进行测试。注意 Windows 7 上的兼容性问题和安全性问题，建议升级到受支持的操作系统。
mysql：简单的概念，用于轻松学习
Apr 10, 2025 am 09:29 AM
MySQL是一个开源的关系型数据库管理系统。1）创建数据库和表：使用CREATEDATABASE和CREATETABLE命令。2）基本操作：INSERT、UPDATE、DELETE和SELECT。3）高级操作：JOIN、子查询和事务处理。4）调试技巧：检查语法、数据类型和权限。5）优化建议：使用索引、避免SELECT*和使用事务。
mysql 和 mariadb 可以共存吗
Apr 08, 2025 pm 02:27 PM
MySQL 和 MariaDB 可以共存，但需要谨慎配置。关键在于为每个数据库分配不同的端口号和数据目录，并调整内存分配和缓存大小等参数。连接池、应用程序配置和版本差异也需要考虑，需要仔细测试和规划以避免陷阱。在资源有限的情况下，同时运行两个数据库可能会导致性能问题。
RDS MySQL 与 Redshift 零 ETL 集成
Apr 08, 2025 pm 07:06 PM
数据集成简化：AmazonRDSMySQL与Redshift的零ETL集成高效的数据集成是数据驱动型组织的核心。传统的ETL（提取、转换、加载）流程复杂且耗时，尤其是在将数据库（例如AmazonRDSMySQL）与数据仓库（例如Redshift）集成时。然而，AWS提供的零ETL集成方案彻底改变了这一现状，为从RDSMySQL到Redshift的数据迁移提供了简化、近乎实时的解决方案。本文将深入探讨RDSMySQL零ETL与Redshift集成，阐述其工作原理以及为数据工程师和开发者带来的优势。
mysql用户和数据库的关系
Apr 08, 2025 pm 07:15 PM
MySQL 数据库中，用户和数据库的关系通过权限和表定义。用户拥有用户名和密码，用于访问数据库。权限通过 GRANT 命令授予，而表由 CREATE TABLE 命令创建。要建立用户和数据库之间的关系，需创建数据库、创建用户，然后授予权限。
