Viewing Information About Server Connection Failure
As soon as a database connection is lost, the ToolsNet 8 data collection service will start buffering results and graphs to the hard disk drive. This feature also protects data if the network connection is lost between the ToolsNet 8 server and the database server.
All results that are collected during this time are stored in temporary files with the extension .que for the data collection classic and as Microsoft message queue (MSMQ) files for the data collection service.
For the data collection classic there is one queue for each controller type:
pf.que for PowerFocus 3000 and Power Focus 4000
pm.que for PowerMACS
op.que for PowerFocus 2000 and other devices reporting with ToolsNet open protocol
The default path to the .que files is C:\Program Files (x86)\Atlas Copco\bin.
Information about database connection failure will be logged in the TNserver.log file which is found in the same folder as the queue files.
For the data collection service there will be one individual MSMQ file for each of the controllers reporting to ToolsNet 8.
The queue files can be viewed using the Computer Management application.
Start the application Computer Management.
In the Computer Management window, select Services and Applications, then Message Queuing, followed by Private Queues.
The log files for the data collection service are located in c:\ProgramData\Atlas Copco\Logs\DataCollectionService\. One log file will be created for each day.
As soon as SQL Server is started, controller data will be retrieved from the .que files and from the MSMQ files and stored in the database.
It may take time to retrieve all data if the database has been stopped for a long time.
