Manually Starting Nodes Defined In The SDF

For many operations in PolySync, using the PolySync Manager to automatically start all nodes that are defined and enabled in the SDF makes the most sense. However, in other cases─such as debugging a particular node─it may be better to manually start up one node at a time. ### 1. Getting the node ID Start the SDF Configurator. ```bash $ polysync-sdf-configurator ``` Next you will get the ID to start the node. Each node─located in the list on the left─has a box indicating which ID this node is associated with. Save this ID for the next step. ![DataGen](https://help.polysync.io/releases/2.0.7//wp-content/uploads/2016/08/nodeid1.png) ### 2. Manually starting the node Now that the unique node ID is known, start up the node using the Dynamic Driver. ```bash $ polysync-dynamic-driver -n 11 ``` This will start up the node in the terminal, and then block, as long it is in normal operation. Take a look at [this](https://help.polysync.io/releases/2.0.7//?p=145) document to get tips on more of the operations that the PolySync Dynamic Driver can perform. It is possible to start multiple nodes. The developer just needs to open up a new terminal and run the Dynamic Driver with the unique node ID. Additional information is written to the PolySync log file. This info can help to figure out why a node may not be working, or to check on normal operation. The log file can be "tailed" to capture the output of the dynamic-driver in real time: ```bash $ tail -f /usr/local/polysync/polysync.log ```
