In fact, this is because when you install Oracle, in order to balance computer performance and database performance, default memory size of 1/8, when the memory itself is relatively large, oracle memory also become large share of physical memory. And generally, our own environment does not need to allocate so much memory to support Oracle, in this case, we can reduce the big problems in the system memory for oracle had sga by modifying values.
Identity with the dba into the oracle, I use sqlplus modified (sqlplus sys / password as sysdba), when using PL / SQL, the Window may be performed in the Command:
(. 1) Parameter Show SGA; - display memory allocation
(2) alter system set sga_max_size = 200m scope = spfile; - modify the size of memory occupied by
the revised restart the Oracle services, and then view the resource Manager, Oracle footprint will be reduced to less 200M. But such a transfer should not be too small when modifying the price paid is the decline in database performance, so modify
