The DBA wants to reserve two thirds of the resources for batch jobs at night. He setsMAX_SHARED_SERVERSto less than one third of the maximum number of processes (PROCESSES). By doing so, the DBA ensures that even if all agents happen to access the database at the same time, batch job...
Number of times that DBWR tried to save a buffer for writing and found that it was already in the write batch. This statistic measures the amount of "useless" work that DBWR had to do in trying to fill the batch. Many sources contribute to a write batch. If the same buffer from diffe...
If latency is observed while working with the Oracle database, the recommendation is to install the latest 64-bit Oracle Data Access Components (ODAC). This will need to be installed on the gateway machine (or on each gateway machine, if the gateway is a cluster). If an Oracle connection...
DB TIME= 所有前台session花费在database调用上的总和时间: 注意是前台进程foreground sessions 包括CPU时间、IO Time、和其他一系列非空闲等待时间,别忘了cpu on queue time DB TIME 不等于 响应时间,DB TIME高了未必响应慢,DB TIME低了未必响应快 DB Time描绘了数据库总体负载,但要和elapsed time逝去时间结合其他...
