数据库创建

没有数据库可参考该步骤创建，否则略过。

dmdba用户：

节点一：

dminit path=/dm/data PAGE_SIZE=32 EXTENT_SIZE=32 CASE_SENSITIVE=y CHARSET=1 DB_NAME=HS01 INSTANCE_NAME=HS01 PORT_NUM=5239

root用户：

cd /home/dmdba/dmdbms/script/root/

./dm_service_installer.sh -t dmserver -dm_ini /dm/data/HS01/dm.ini -p HS01

节点二：

dminit path=/dm/data PAGE_SIZE=32 EXTENT_SIZE=32 CASE_SENSITIVE=y CHARSET=1 DB_NAME=HS02 INSTANCE_NAME=HS02 PORT_NUM=5239

root用户：

cd /home/dmdba/dmdbms/script/root/

./dm_service_installer.sh -t dmserver -dm_ini /dm/data/HS02/dm.ini -p HS02

打开归档

节点一：

ALTER DATABASE MOUNT;

ALTER DATABASE ADD ARCHIVELOG 'TYPE = LOCAL,DEST = /dm/data/HS01/arch,FILE_SIZE = 128,SPACE_LIMIT = 1024';

ALTER DATABASE ARCHIVELOG;

ALTER DATABASE OPEN;

select para_value from v$dm_ini where para_name in ('ARCH_INI');

节点二：

ALTER DATABASE MOUNT;

ALTER DATABASE ADD ARCHIVELOG 'TYPE = LOCAL,DEST = /dm/data/HS02/arch,FILE_SIZE = 128,SPACE_LIMIT = 1024';

ALTER DATABASE ARCHIVELOG;

ALTER DATABASE OPEN;

select para_value from v$dm_ini where para_name in ('ARCH_INI');

开启附加日志

两节点分别执行：

SP_SET_PARA_VALUE(1,'RLOG_APPEND_LOGIC',1);

select para_value from v$dm_ini where para_name in ('RLOG_APPEND_LOGIC');

创建辅助表

两节点分别执行：

set define off

set char_code utf8

start /dmhs/scripts/ddl_sql_dm8.sql

共9个辅助表，4个触发器:

select owner, table_name from dba_tables where owner = 'SYSDBA' and table_name like 'DMHS%' and status = 'VALID';

select owner, trigger_name from dba_triggers where owner = 'SYSDBA' and trigger_name like 'DMHS%' and status = 'Y';

创建连接用户

两节点分别执行：

CREATE TABLESPACE HSEXEC DATAFILE 'HSEXEC.DBF' size 128;

CREATE USER HSEXEC IDENTIFIED by "HSEXEC" DEFAULT TABLESPACE HSEXEC DEFAULT INDEX TABLESPACE HSEXEC;

GRANT VTI TO HSEXEC;

GRANT PUBLIC TO HSEXEC;

GRANT RESOURCE TO HSEXEC;

GRANT DBA TO HSEXEC;

创建测试用户和表

略

4、同步配置

修改服务配置

节点一：

cd /dmhs/bin

cp TemplateDmhsService DmhsService

vim DmhsService

节点二：

同上

双向同步配置

节点一：

cd /dmhs/bin

vim dmhs.hs

exec_policy=2表示执行事务出错时，忽略出错的操作后继续执行；ddl_continue=1表示DDL操作同步出错时，继续往下操作。
