今天,无意中发现shared pool很大,占到4G,不知道是什么问题?
show parameter shared
hi_shared_memory_address integer 0
max_shared_servers integer 20
shared_memory_address integer 0
shared_pool_reserved_size integer 4194304
shared_pool_size integer 83886080
shared_server_sessions integer 181
shared_servers integer 1
shared_pool_size大小仅仅80M.

发现shared pool 的session param values占用很大,目前系统运行正常,是遇到什么BUG吗?
