7.13.2 Points to be considered during UOC execution
The resources which are reserved during the execution of UOC are not released even after the process ends. The resulting increase in the load of the entire system makes Java heap insufficient which may lead to the occurrence of OutOfMemoryError.
The following functions use UOC and executing these functions, may lead to the occurrence of the OutOfMemoryError. To prepare for OutOfMemoryError, you must implement processes such as process to release resources appropriately and error processing such as rollback at the time of creating UOC.
-
Invoke Java activity
-
User-defined function
-
Character code conversion UOC
-
Component-common UOC
-
Custom reception
-
General custom adapter
