Description | We have 4 levels of nodes but with different link options, so we needed to create more than 4 node groups to configure links and routers: ROOT | --------------------- | | SERVER1 SERVER2 | ... ------------------------ | | | | | ADM1 ADM2 ADM3 | | | | | | ----- ----- | | | | | | | | S11 S12 S21 S22 S01 S02 ROOT, SERVER and ADMinistration levels can register childs. Store nodes can register/synchronize on a SERVER node or on an ADMinistration node (customer main server), so there are 2 node groups defined for Store level. After registration at ADM level, the Store level node FAILED to connect: Client side log: 2012-02-02 13:50:21,440 INFO [SymmetricDS] [SymmetricDS-job-7] Unregistered node is attempting to register 2012-02-02 13:50:21,485 INFO [SymmetricDS] [SymmetricDS-job-7] Using registration URL of https://adm1url:1234/sync/registration?nodeGroupId=STORE_ADM&externalId=11&syncURL=https%3A%2F%2Fanyurl%3A1895%2Fsync&schemaVersion=%3F&databaseType=PostgreSQL&databaseVersion=9.1&symmetricVersion=2.5.3 2012-02-02 13:50:22,610 ERROR [SymmetricDS] [SymmetricDS-job-7] Node identity is missing after registration.

I ran Symmetric of ADM node in debug mode and found that the recursive funcion NetworkedNode.getNumberOfLinksAwayFromMe may have a bug: protected int getNumberOfLinksAwayFromMe(String nodeId, int numberOfLinksIAmFromRoot) { if (!node.getNodeId().equals(nodeId)) { if (children != null) { for (NetworkedNode child : children) { if (child.getNode().getNodeId().equals(nodeId)) { return numberOfLinksIAmFromRoot + 1; } else { int numberOfLinksAwayFromMe = child.getNumberOfLinksAwayFromMe(nodeId, numberOfLinksIAmFromRoot + 1); if (numberOfLinksAwayFromMe > numberOfLinksIAmFromRoot) { return numberOfLinksAwayFromMe; } } } } } return numberOfLinksIAmFromRoot; } If we have more than one children, it always exits at the first step and it never iterates over the rest of children. I still don't understand all the code, but when I fixed this function in the way I think it should be (iterating over all children), the registration succeded. Another problem we are having is that the registered Store node (child of a specific ADMinistration node) replicates up to the ROOT and down to all other ADM servers and they start to generate batches for that Store that they are not parent of. I think the sym_node row for that store should not replicate to all ADM nodes. |
