根据资料如果FAST_START_MTTR_TARGET被指定,LOG_CHECKPOINT_INTERVAL不能被设置为0。
哪个文档说不能被设置为0?

When fast-start checkpointing is enabled, Oracle automatically maintains the speed of checkpointing so that the requested MTTR is achieved. Setting a non-zero value for LOG_CHECKPOINT_INTERVAL or LOG_CHECKPOINT_TIMEOUT interferes with fast-start checkpointing, resulting in a different MTTR than expected.
