DFstudyDiag — Report (diagnose) the current status of a study database server
DFstudyDiag
{-s #}
There are a variety of consistency checks that must be in place for a study server to operate correctly. If one or more of these consistency checks fails, it may be difficult for a user to determine the failure condition so that it can be remedied. DFstudyDiag is the utility to use in situations like this.
DFstudyDiag checks a variety of places while diagnosing a study server. It consults with the DFdiscover master, reviews the DFdiscover studies database, communicates with the operating system's portmapper, and also interacts with one or more DFdiscover slaves. DFstudyDiag displays its progress which each of these interactions as these proceed.
DFstudyDiag exits with one of the following statuses:
0 | The command was successful and the study server is operational and responding correctly, or the study server has been disabled. |
1 | The command was successful and the study server is not responding, or the command failed because there was an error in the command-line arguments. |
