文档解释

ORA-15504: cannot start workload capture because instance string not present in RESTRICTED SESSioN mode

Cause: The NO_RESTART_MODE option in DBMS_WORKLOAD_CAPTURE.START_CAPTURE was FALSE, therefore all the active instances were expected to be in the RESTRICTED SESSION mode.

Action: Start all instances using STARTUP RESTRICT or execute ALTER SYSTEM ENABLE RESTRICTED SESSION on all active instances before issuing DBMS_WORKLOAD_CAPTURE.START_CAPTURE.

ORA-15504：由于实例字符串没有出现在RESTRICTED SESSION模式中，因此无法启动工作负载捕获。
