We are trying to upgrade from 4.2 EE to 8.2 CE. When ran a trf where lkp table having 10000000, after reading 7000000 getting Exception in thread "qtp1982591789-180" java.lang.OutOfMemoryError: GC overhead limit exceeded.
Got this error in 8.2 CE, but ran in 4.2 EE. Any inputs on how to resolve the issue.
