fallback information, and when we commit a transaction, the fallback information is no longer working for transaction rollback and database recovery. However, for a long transaction, it has the function of read consistency, which guarantees that the information queried is always the old information. In addition, the implementation of the various flashback operations of the database also requires information in the fallback segment. Oracle automatically adjusts the retention time of the fallback

Topics from StackOverflow why are processing a sorted array faster than an unsorted array?Here is a piece of C + + code that seems very peculiar. For some strange reason, sorting the data miraculously makes the code almost six times faster:#include { if (Data[c] >=) sum + = Data[c]; } } Double elapsedtime = static_cast without std::sort (data, data + arraySize); , the code runs in 11.54 seconds. with the sorted data, the code runs in

There is a problem in the field, after Oracle has been running for a while, the number of process overflows and the new connection fails. Through analysis, the ARCSOC process of ArcGIS Server is found to grow in no segment. ARCSOC is a container process for ArcGIS server that loads ArcGIS object.The plan attempts to solve/mitigate this problem in two ways.Method OneAdjust the configuration information for each service as follows: Reduce the maximum time that a space instance can be run

resulting results must already be recorded in the Redo log file, the Smon process rolls forward according to the redo log file after the instance restarts. The time used for recovery after an instance failure is determined by the size of the interval between two checkpoints, and you can set the frequency of the checkpoint execution by four parameters: Log_checkpoint_interval: Determines the system physical block (redo) that writes redo log files between two checkpoints.
