问题定位：每天晚上十点的时候运行自动SQL优化的任务时报错内存不足。

alert报错：

解决：

适当增大pga，给sharepool、largerpool等设置一个最小值。

Mon Jan 07 08:30:49 2019
ALTER SYSTEM SET java_pool_size=‘100M‘ SCOPE=SPFILE;
ALTER SYSTEM SET large_pool_size=‘100M‘ SCOPE=SPFILE;
ALTER SYSTEM SET shared_pool_size=‘500M‘ SCOPE=SPFILE;
Mon Jan 07 08:31:26 2019
ALTER SYSTEM SET db_cache_size=‘1000M‘ SCOPE=SPFILE;
Mon Jan 07 08:32:03 2019
ALTER SYSTEM SET pga_aggregate_target=‘3000M‘ SCOPE=SPFILE;

内存自动管理的问题，建议不适用内存自动管理，设置sga_target=0.
