Oracle data import and export problem records

I believe everyone will be familiar with Oracle data import and export. As I have encountered similar problems many times, record them.Question: How can I import and export data between different users? Instance: Use twc to export twc. dmp data from a remote database, and then import the data to the database whose original user name is Nsw;The procedure is as follows:1. Export data from a remote database: c

How to see the time series diagram--nand Flash read operation detailed

timesGive a description of the corresponding time label in the data sheet.Likewise, we follow the steps in the above analysis1 here is the address latch is the timing, then we have to pay attention to the fact that only the ALE is high level during this time series. (Write command Ah, ale active (High level) indicates that the current data is actually an address) CLE at this time must be low, you can do without tube2 So, the ALE is a low-level period, and most of the other pins are shaded in sh

1, to detect the rollback segment contention Select sum (gets), sum (Waits), sum (Waits)/sum (gets) from V$rollstat; The sum (Waits) value should be less than 1% of the sum (gets) valueThe contention of the rollback segment will degrade the performance of the system. Gets represents the number of times the volume segment was accessedWaits represents the number of processes that the process waits to return to the volume segmentIf the ratio of gets to waits is greater than 2% indicates the existen
