When a table goes from 100,000 rows to 150,000 rows, that's not a terribly significant change.
I am Loading large no of rows into a table from a csv data file . In my opinion, what you may wish to do for the period of your data load, is make the indexes UNUSABLE, then when you're done, REBUILD them. I would drop the index(es), load the data and then recreate the index.
JRockit overrides class files which relate closely to the JVM, therefore retaining API compatibility while enhancing the performance (processing speed) of the JVM.
And when they do run statistics then they encounter a number of problems.In contrast, if you have invalid or out-of-date statistics, it can lead the SQL Server engine to take the wrong path to the data, and taking the wrong path means that an index scan is made when an index seek would have been appropriate or a seek is performed against the wrong index.Even worse, it would perform a table scan instead of any index operation at all.Those are the times when system statistics are most important because that’s when the system may be taxed.In your experience, how often should Oracle database statistics be run?
