TIBCO Data Virtualization | All Supported versions |
When attempting to connect to a TIBCO Data Virtualization server, it is possible that an error message may appear in the cs_server.log. One such error is outlined below:
=======================================
WARN [main] 2023-02-28 13:08:09.201 -0800 DistributedTaskPrimitives - Attempt (1) to DV Login failed. Cause: java.net.ConnectException: Connection refused (Connection refused)
=======================================
This warning message indicates that the Drillbit process took longer than usual to run, but it has not yet failed completely. The Drillbit process is designed to retry login attempts multiple times before it completely fails, which is why you may see this warning message multiple times before the system starts working properly.
It is important to note that Drillbit is utilized by the Massively Parallel Processing(MPP) engine to process requests, and MPP is set to true by default on Linux machines.
When MPP (Massively Parallel Processing) is enabled, it attempts to start itself during server restart, which can lead to warning messages being displayed.
Despite the warnings, there is no need for concern as the Drillbit process is making several attempts to start up, rather than failing altogether. Therefore, it is safe to ignore these warning messages as they are simply part of the normal process for starting up the Drillbit process.
