Description
The OTX MutexGroup activity is used to synchronize access to data in an Parallel activity. She is as well structured as an Group activity, however, it prevent simultaneous execution of contained activities by more than one thread. The term Mutex means "mutual exclusion" or mutual exclusion. So always just a MutexGroup can run. Thus can be used to ensure that shared data not uncoordinated can be changed, see Thread-safe.
|
Important: If in different lanes of a parallel activity reading or writing data is accessed, the range in a MutexGroup activity should be. Read-only, no MutexGroup is necessary. |

|
Important: Please keep in mind that the MutexGroup has strong influence on the performance of a parallel activity and use it only where it is to the described problems can occur. |
