Due to the continuous updating of hardware technology, Win7 system gradually become mainstream, and computer memory gradually increased, in order to make full use of memory resources (because 32 of the system can only use up to 3G of memory), improve system performance, many people began to use the Win7 (64Bit) system. A 64-bit Oracle database is installed on a 64-bit system, but there is no corresponding 64-bit PL/
