The Comm. Bridge allows external enabling and disabling of Trace level logging. This capability activates the collection of trace data without the need to use the Comm. Bridge GUI interface. The logging level change is triggered by either of the two notification files that exist in the Comm. Bridge install directory.
The file CBTRACE_ALL triggers a log level change for all active Comm. Bridges that find this file in their %APPDATA%\CA\Gen xx\cb directory. This is a way to enable logging for multiple Comm. Bridges at the same time.
The second file is CBTRACE_nnnn, where nnnn is the port number of a client. Placing this file in the %APPDATA%\CA\Gen xx\cb directory triggers a log level change but only for the client on that port.
Note: xx refers to the current release of CA Gen. For the current release number, see the Release Notes.
In both the cases, logging level is changed from the current level to Trace. When a trace notification file is removed, the logging level is reset to its previous value. This is particularly useful when the Comm. Bridge is installed as a system service or when multiple instances of a Comm. Bridge have been configured and simultaneous logging is needed for all actives Comm. Bridges.
The Comm. Bridge checks for the existence of these notification files every five seconds.
