Starting and stopping the DBLogger
The DBLogger is started by running a WCCOActrl Manager with the script
DBL_Control.ctl
.
This script is the actual DBLogger and enables writing from WinCC OA to the external database configured in the DBLogger. The script must run continuously. Set the start mode "always" for the CTRL Manager.
The DBLogger can be stopped in the configuration panel
DBL_Para.pnl
by pressing the Restart DBL_Control.ctl
button having already deleted the "always" option (in the console). The write
commands waiting to be performed are terminated properly (COMMIT) before the CTRL
Manager is shut down.
If the CTRL Managers are configured with weighting in case of a redundant project (see also Configuration of the error weighting), unwished redundancy switching may happen!
