Move event queue files

Occasionally, you might want to remove an event-queue from the system, such as when the system cannot manage the load of a large backlog of events.

In most cases the event queue is PI\dat\pimq0000.dat. However, it is possible to have multiple event queue files. The utility piartool -qs indicates if your system uses multiple queues. If multiple queues are used, the queue naming convention is pimqNNNN.dat, where NNNN is a four-digit integer.

1. Stop PI Snapshot Subsystem and PI Archive Subsystem.

2. Move PI\dat\pimq*.dat to a different folder than \PI\dat for later reprocessing.

   If you configured the default event queue path to a different location than \PI\dat, move the event queue files from this location

3. Restart PI Snapshot Subsystem and PI Archive Subsystem.
