hi all
man top o: VIRT -- Virtual Image (kb)
The total amount of virtual memory used by the task. It includes all code, data and shared
libraries plus pages that have been swapped out. (Note: you can define the STATSIZE=1 environment
variable and the VIRT will be calculated from the /proc/#/state VmSize field.)
Делаю рестор через сервисы базы, одновременно на 2.5 и 3.0.
