Deadlock10Jul 3 2013 — edited Jul 17 2013

Hi,

I am currently working in Application Support from past 4 years and I have applied for a opening in Oracle Production Support environment and it is different from DBA.

So far i have never worked in Oracle Production Support so i am curious to know what exactly the roles and Responsibilities for this position.

What kind of issues comes and how to troubleshoot them?

I actually need to understand the nature of this job in detail and few interview questions that can be asked for this position.

Any kind of help will be appreciated.

Thanks in Advance,

Regards.

Such optimization are done by JIT compiler (not by javac).
C++ have just the same problems, exceptions make CFG analisis more difficult but not impossible.
PS You can read JLS about volatile variables there some additional restrictions on them.

zhmur is right, this makes optimization harder not impossible.

There are sicentific papers aimed at making more analysis/optimization in the presence of many try/catch blocks. For instance, JIT can reorder statements, and then put compensation code into the catch body, recovering program state back if an exception was thrown.

General principle is simple: exceptions are rare. So JIT optimizes the "normal" control flow by the cost of more complex catch body.

You may also look/post to the comp.compilers newsgroup regarding compilers and optimization techniques
