SymmetricDS 数据同步系统

SymmetricDS 数据同步工具（免费开源！！）

目前网上只有英文文档，看起来比较吃力。

下面博客中有详细说明：

步骤大致如下：（具体详细步骤已经制作成视频！欢迎下载！）

SymmetricDS 数据同步系统

创建表应用表(两个库要同步)

创建系统表
sym -p root.properties --auto-create 

将数据库样本导入
sym -p root.properties --run-sql insert_sample.sql 
delete from sym_node_group_link;
delete from sym_node_group;
delete from sym_node_identity;
delete from sym_node_security;
delete from sym_node;


insert into sym_node_group (node_group_id, description) 
values ('zjg', 'root');
insert into sym_node_group (node_group_id, description) 
values ('home', 'client');

insert into sym_node_group_link (source_node_group_id, target_node_group_id, data_event_action)
values ('zjg', 'home', 'P');   --(P = Push, W = Wait for Pull) 
insert into sym_node_group_link (source_node_group_id, target_node_group_id, data_event_action)
values ('home', 'zjg', 'W');

insert into sym_node (node_id, node_group_id, external_id, sync_enabled)
values ('00000', 'zjg', '00000', 1);
insert into sym_node_identity values ('00000');


-- Channels
insert into sym_channel 
(channel_id, processing_order, max_batch_size, enabled, description)
values('CHANNEL_ZJG', 1, 100000, 1, 'ZJG SEND FROM HERE');

insert into sym_channel 
(channel_id, processing_order, max_batch_size, enabled, description)
values('CHANNEL_HOME', 1, 100000, 1, 'HOME SEND FROM HERE');


-- Triggers
insert into sym_trigger 
(trigger_id,source_table_name,channel_id,last_update_time,create_time)
values('TIGER_EPORT_ID','ZJG_EPORT','CHANNEL_ZJG',current_timestamp,current_timestamp);

insert into sym_trigger 
(trigger_id,source_table_name,channel_id,last_update_time,create_time)
values('TIGER_HOME_ID','ZJG_HOME','CHANNEL_HOME',current_timestamp,current_timestamp);


-- Routers
insert into sym_router 
(router_id,source_node_group_id,target_node_group_id,create_time,last_update_time)
values('zjg_home_router', 'zjg', 'home', current_timestamp, current_timestamp);

insert into sym_router 
(router_id,source_node_group_id,target_node_group_id,create_time,last_update_time)
values('home_zjg_router', 'home', 'zjg', current_timestamp, current_timestamp);


-- Trigger Router Links
insert into sym_trigger_router 
(trigger_id,router_id,initial_load_order,last_update_time,create_time)
values('TIGER_EPORT_ID','zjg_home_router',100,current_timestamp,current_timestamp);

insert into sym_trigger_router 
(trigger_id,router_id,initial_load_order,last_update_time,create_time)
values('TIGER_HOME_ID','zjg_home_router', 200, current_timestamp, current_timestamp);



启动服务端  客户端 服务
sym -p root.properties --port 8080 --server 
sym -p client.properties --port 9090 --server 

设置服务端节点 
sym -p root.properties --open-registration "zjg,1"  (维护在sym_node表中)

加载服务端节点
sym -p root.properties --reload-node 1  （这里的1，必须是已经在sym_node中的节点ID）
