CONNECTION 过程 - 生成连接度量值的报告
CONNECTION 过程收集每个连接的监视器数据并产生文本格式的报告。
语法
参数
- 监视时间间隔
- 类型为 INTEGER 的可选输入参数，用于指定在报告所收集监视数据之前，收集这些数据的持续时间（以秒计）。 例如，如果指定监视时间间隔为 30 秒，那么该例程会调用表函数，等待 30 秒并再次调用表函数。 然后该例程会计算差别，这些差别反映时间间隔期间的更改。 如果未指定 monitoring_interval 参数（或者指定了 NULL），那么缺省值为 10。 有效输入的范围是整数值 0 到 3600（即，最长 1 小时）。
- application_handle
- 类型为 BIGINT 的可选输入参数，用于指定标识连接的应用程序句柄。 如果未指定 application_handle 参数（或者指定了 NULL），那么对于每个连接，报告都将包括一节。 缺省值为 NULL。
权限
需要以下特权：
- 对 MONREPORT 模块的 EXECUTE 特权
示例
以下示例演示调用 CONNECTION 过程的各种方法。
此示例对所有连接生成一个报告，其中显示的数据对应 30 秒时间间隔：
call monreport.connection(30); 此示例对应用程序句柄为 34 的连接生成报告。 系统将根据源表函数中累积的绝对总数（而不是根据当前时间间隔）显示数据：
call monreport.connection(0, 34);下一示例对应用程序句柄为 34 的连接生成报告。 显示的数据对应于 10 秒时间间隔。
call monreport.connection(DEFAULT, 34);最终示例对所有连接生成缺省报告：显示的数据对应时间间隔 10 秒：
call monreport.connection; Result set 1
