问题 I have a Spring boot maven project with SymetricDS. When I start the application in embedded mode, even if I have a Tomcat with Spring boot, it is looking for Jetty.

问题 I need to extend Symmetric DS functionality by extending the interfaces it provides. Does anyone has any idea what the development process should be? In the documentation it only explains where to put the JAR file (containing the classes extending the interfaces) and how to add them to spring context but doesnt explain how to develop them. i.e. what libraries are needed to get the interfaces and what process should be followed to develop/test. It seems very cumbersome to each time modify and

问题 Now I try to replicate DDL statements(like create, alter, drop) between different databases with the help of Symmetric-DS. I've found this page https://www.symmetricds.org/docs/how-to/sync-schema-ddl-changes and found that it could be done it that way: bin/symadmin -e root-000 --node=001 sync-triggers bin/symadmin -e root-000 --node=001 send-schema But, for now I cannot understand that is there possibility to replicate DDL statements automatically? I.e. I create table on one database and it

问题 I'm testing SymmetricDS and I'm having some doubt about which approach I should use to synchronize some specific tables. I have two application, the first is a ERP and the second is a PDV. Some tables can be synchronized to all PDV databases, however, in some tables the row should synchronize to a specific PDV instance: In this diagram, the red rectangles show which table need synchronize, and the green arrow show the column where we can identify which SymmetricDS instance will synchronize.

问题 I have a 3 server running SymmetricDS. Say i have node 1 which is master, node 2.node 3 are child. When some data is being inserted into node 2 it's being synced to node 1 and similarly node 3's data is being syncing with node 1. But node 2 data is not going to node 3. I do not know where to solve this issue. Here is the sample configuration sql -- ========================================= -- channel starts insert into sym_channel (channel_id, processing_order, max_batch_size, enabled,

问题 I'm trying to embedded Symmetricds 3.7 in a java application which uses H2 database. The application is a client node and uses the class ClientSymmetricEngine from SymmetricDS API. The master node runs standalone symmetricds server and I was able to synchronize the data when I used an already configured databsae from previous tests in the application. When running the application on a new database, it throws this exception: java.lang.IllegalStateException: This node has not been configured

问题 I have the following use case: A database A (Master) and a database B (slave), located on diferent machines. I want to synchronize the Database A with Database B. I want to create a java application using SymmetricDS embedded. As there is no documentation on how to perform this, i want a sample example or a documentation . Please help me I'm stuck. 回答1: this an example how run the Symmetric engine server in embedded mode , and it works perfectley for me : public class ClientNode { private

问题 I am using SymmetricDS version 3.9.15 on Azure SQL for both master and slave databases. I am able to configure the tool correctly to synchronize the databases but while publishing the database project the SqlPackage command gives an error due to the fully qualified name(including catalog name & schema name) of the table and function in the following trigger.
