Java not updating

So instead of thinking is it worth using threads or not, I'd rather sit down and do it without any threads and see how it performs and then see what is the issue I'm facing and if I face any serious issue at all. I have had similar loads which ran for about 4 to 5 hours. And your work to do it in the straightforward way would not be in vain anyway - I'm sure you'll be able to re-use big parts of the code I don't think there is any strict limit.

I was thinking to do this on the database side but was apprehensive as i have more than 5 million records to work with. That's tiny for a Map, which is the new record for update Sorry, I did not get you. When it comes to updating rows, as you saw, database is definitely much better place to deal with You can do it just row by row raeding rthe rows - calculation the remaning rcolumns and filling them in Actually database and JDBC talke care of the memory issues for you, so it is not that bad as you may think.

I need to decide as if i take either to do it on the database side or to do it externally via files, later i would not be able to turn back. You can devise some way to select and update grouped in certain chunks.

During the automatic update from JRE 7 to JRE 8, if a user only has one version of Java 7 the auto-update process will replace that JRE 7 with the latest version of JRE 8 leaving only JRE 8 in the system.

OS X users can only have one JRE available through web browsers so OS X users will only have JRE 8 available through the web browser after the upgrade On Windows, the auto-update process updates only the latest JRE on your system.

Later i have the full data for say the third record i.e Name: Gaara Id:1 age:22 address:sand rank:100 Now how do i go and update the original data in the file as name|id|age|address|rank naruto|2|24 vegeta|3|25 gaara|1|22|sand|100 Please help...Its intuitive dashboards are customizable, so you can create systems that work for you.I haven't been able to update Java under 8.1 and, since uninstalling Java, I now can't install it. I get a "Java install did not complete Error Code 2" message after Java has downloaded and gone through some process of installing and before it completes. has found no other references to this problem/error code and, of course, there is no way to contact them.I'm pretty sure all that stuff in math and dates is possible to do within oracle itself within SQL.In general, if the question is about speed, my way is first to try in straightforward simplest way and then assess what kind of issues you are facing in the sense of timing the thing is that let's assume threads will be successful and with a lot of additional work may end up say in saving time let's say even two, or assuming a lot, three times but most probably would not end up in orders of magnitudes, whereas moving to PL/SQL from Java in many cases produces order of magnitude saving in time.To achieve this goal Windows and OS X users that rely on Java’s auto-update mechanism will have their JRE 7 replaced with JRE 8.The Java auto-update process updates the latest version of Java on a user’s Windows and OS X machine.I could not have these many calculations in a stored proc.What else did you have in mind and what is not suitable with java using threads.I don't see any reason why you can't have 4 different temp tables I would first start doing it without threads - it is additional complication - look at your times real life situations, if this is some application which you need to run once to update or you'll be using it all the time see how it goes first in termas of time especially if it ios mostly one time opperation- if you need it then think about threads @for_yan and @CEHJ: Thanks for the reply.This would be a one time operation or load that i would be performing once in a few months.
