9) 数据操纵语言(DML): Data Manipulation Language(包含:insert、update、delete):用于改变数据库数据
10) 数据控制语言(DCL): Data Control Language(包含:grant、revoke):用于执行权限授予和收回操作(同数据操纵语言DML会自动提交事务)
11) 事务控制语言(TCL):Transactional Control Language(Commit、Rollback、Savepoint):用于维护数据的一致性
12) Recursive Calls:Number of recursive calls generated at both the user and system level.(用户与系统造成的递归调用数)
13) DB Block Gets:请求的数据块在buffer能满足的个数(Number of times a CURRENT block was requested.)
14) Consistent(一致性) Gets:数据请求在回滚段Buffer中的总数 (Number of times a consistent read was requested for a block.)
15) Physical Reads:从磁盘读到Buffer Cache数据块数量(Total number of data blocks read from disk. This number equals the value of "physical reads direct" plus all reads into buffer cache)
16) Sorts (disk):Number of sort operations that required at least one disk write. Sorts that require I/O to disk are quite resource intensive. Try increasing the size of the initialization parameter SORT_AREA_SIZE.(排序运算需要的最小磁盘写)
