把Oracle单表流复制搞定,由于oracle stream 操作步骤多,之前遇到许多问题,没有理清思路或者说自己对此的理解不够,所以失败。
把Oracle单表流复制搞定,由于oracle stream 操作步骤多,之前遇到许多问题,
没有理清思路或者说自己对此的理解不够,所以失败。对于重要表,流复制类似dataguard应用日志,主服务器
捕获,然后传递,从服务器接受,如此而以。简单记录一下主要步骤。
1 主服务器 os: windows sid:rman 数据库版本10.2.0.1
从服务器 os: windows sid format 数据库版本10.2.0.1
2 主、从数据库分别执行如下的语句:
Sqlplus ‘/ as sysdba’
alter system set aq_tm_processes=2 scope=both;
alter system set global_names=true scope=both;
alter system set job_queue_processes=10 scope=both;
alter system set parallel_max_servers=20 scope=both;
alter system set undo_retention=3600 scope=both;
alter system set nls_date_format='YYYY-MM-DD HH24:MI:SS' scope=spfile;
alter system set streams_pool_size=25M scope=spfile;--这个我没执行,理由是oracle自动分配了
alter system set utl_file_dir='*' scope=spfile;
alter system set open_links=4 scope=spfile;
3 主从机设置归档 mout状态下alter database archivelog 另开启alter system set log_archive_start=true;
查看归档是否成功select recid, name, first_time from v$archived_log;
4 主从机表空间和用户
create tablespace stream_tbs datafile 'g:\oracle\oradata\rman\stream01.dbf' size 200m
autoextend on extent management local uniform size 1m segment space management auto;
表空间已创建。
-- 创建streams管理用户,并授予dba权限
JSSWEB> create user test identified by test default tablespace stream_tbs;
用户已创建。
--将logminer的数据字典从system表空间转移到新建的表空间,防止撑满system表空间
execute dbms_logmnr_d.set_tablespace('tbs_stream');
-- 由于streams用户操作需要较多权限,此处仅用于演示,简便期间直接授予dba权限
授权test管理用户
JSSWEB> grant dba to test;
begin
dbms_streams_auth.grant_admin_privilege(
grantee => 'test',
grant_privileges => true);
end;
5 主从机表空间和用户
create tablespace stream_tbs datafile 'd:\oracle\oradata\rman\stream01.dbf' size 200m
autoextend on extent management local uniform size 1m segment space management auto;
表空间已创建。
-- 创建streams管理用户,并授予dba权限
JSSWEB> create user strmadmin identified by strmadmin default tablespace stream_tbs;
用户已创建。
--将logminer的数据字典从system表空间转移到新建的表空间,防止撑满system表空间
execute dbms_logmnr_d.set_tablespace('tbs_stream');
-- 由于streams用户操作需要较多权限,此处仅用于演示,简便期间直接授予dba权限
授权test管理用户
JSSWEB> grant dba to strmadmin ;
begin
dbms_streams_auth.grant_admin_privilege(
grantee => 'strmadmin',
grant_privileges => true);
end;
6 配置网络连接
主数据库(tnsnames.ora)中添加从数据库的配置。
RMAN =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.103)(PORT = 1521))
)
(CONNECT_DATA =
(SID = rman)
(SERVER = DEDICATED)
)
)
配置从环境tnsnames.ora
从数据库(tnsnames.ora)中添加主数据库的配置。
FORMAT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.104)(PORT = 1521))
)
(CONNECT_DATA =
(SID = format)
(SERVER = DEDICATED)
)
)
7 创建database link
主:create database link format connect to strmadmin identified by strmadmin using 'format';
从:create database link rman connect to strmadmin identified by strmadmin using 'rman ';
然后相互tnsping 或 select sysdate from dual@format/rman;
8 主库 exec dbms_streams_adm.set_up_queue();
从库 exec dbms_streams_adm.set_up_queue();
9 创建捕获规则
begin
dbms_streams_adm.add_table_rules(
table_name => 'scott.emp',
streams_type => 'capture',
streams_name =>'capture_stream',
queue_name => 'test.streams_queue',
include_dml => true,
include_ddl => true,
inclusion_rule => true);
end;
--创建传播规则
begin
dbms_streams_adm.add_table_propagation_rules(
table_name =>'scott.emp',
streams_name => 'sour_to_targ',
source_queue_name =>'test.streams_queue',
destination_queue_name => 'strmadmin.streams_queue@format',
include_dml => true,
include_ddl => true,
source_database =>'rman',
inclusion_rule => true,
queue_to_queue => true);
end;
select capture_name,status from dba_capture;

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
