Debugging tips

The following tips can help you debug your UDx before deploying it in a production environment.

Use a single node for initial debugging

You can attach to the OpenText™ Analytics Database process using a debugger such as gdb to debug your UDx code. Doing this in a multi-node environment, however, is very difficult. Therefore, consider setting up a single-node database test environment to initially debug your UDx.

Use logging

Each UDx has an associated ServerInterface instance. The ServerInterface provides functions to write to the database log and, in the C++ API only, a system table. See Logging for more information.
