Batch thread updates running?

Question

What did just happen? How come the Oracle Database category list page shows almost every forum with a Last post updated around "Nov 22, 2012 8:01 AM"?
Same thing with the first forums on the Fusion Middleware category page as well.
Noticed the same thing in the top Java category (but with dates around "Nov 21, 2012 9:19 AM").
Related to upgrade preparations perhaps?

Answer 1

Well your problem is that you are not actually starting your pdf threads, you are simply calling the run method of the object. You need to call start() in the mft object. The start method causes the underlying system thread to be started then the execution of the run method is carried out within that thread.
You should check why calling mft.start() does not result in the run method being called.
1- Threads never run in parallel on a single CPU machine, they share time on the CPU. No CPU can run more than one process simultaneously even if the OS makes it look that way.
2- The process you are carrying out is not going to be performant enough using multi-threading, you are simply going to clog your machine with Threads which do a lot of I/O which will cause them to spend most of their time in the blocked state (this means that they automatically yield to other threads. It is actually more performant to use a single thread to do this job.
