		<title>WLI Process Statuses</title>
		<description><![CDATA[Weblogic Integration throws unbelievable errors sometimes, even when you haven&#8217;t changed squat.
I deleted some of the suspended and frozen transactions and it worked on one particular server.
(though i am still struggling with another one)
In any case,
WLI_PROCESS_INSTANCE_INFO.PROCESS_STATUS column values and meanings.
0 = Running
1 = Aborted
2 = Suspended
3 = Complete
4 = Frozen
5 = Terminated

		<title>Weblogic WLI Error Resolution</title>
		<description><![CDATA[UPDATE!
Before you try to run the scripts, there&#8217;s a simple resolution: try restarting the DB instance. Maybe that&#8217;s what is causing this error. Sometimes there is some issue with the TNS Listener and that might throw this error.
After a loooooong time spent debugging this issue, i have found the solution.
So the situation is this. you [...]]]></description>

		<title>Diff. between remove() for Entity and Session Beans&#8230;</title>
		<description><![CDATA[&#8230;is similar to the difference between hanging up on a telephone conversation and actually killing the caller on the other end. Both end the conversation, but the end results are a little different.

		<title>Constraints To Computation</title>
		<description><![CDATA[&#8220;1 kilogram of matter confined to 1 liter of space can perform at most 1051 operations per second on at most 1031 bits of information.&#8221;
- Ultimate physical limits to computation

		<description><![CDATA[Maximizing usage of available power capacity is the key!
Power subscription at the facility level seems promising (whatever that means)
large systems should utilise power efficiently.
Q and A going on&#8230;
&#8230; almost ending, so i guess i can switch this off.
Oh
I forgot.
Conclusion (from Luiz&#8217;s slides):
Power/ energy efficient and fault tolerance are central to the design of large scale [...]]]></description>

		<description><![CDATA[Power efficient datacenters:
Idle machines also consume power.
Compared to humans, power consumption for machines is waay high, since humans use less power while resting, but high while performing. Machines don&#8217;t have that high gap between idle and high activity power consumptions.

		<description><![CDATA[&#8220;Fault Tolerance systems lie.
Disk failures: Failure rates < 1% per year.
Study conducted proves that irrespective of age, disk failed... (couldn't catch that)
also,  Temperature is not a major criterion for disk failures.
SMART disks&#8230;self monitoring. (!)
Even then, 56% of disks failing had no predictable behavior.
Well, more bad news: 70% of drives survive for 8 months. (So [...]]]></description>

		<description><![CDATA[So on stage, Luiz Barroso!
&#8220;Single fault will bring down the large scale computer systems that use shared memory programming model, and fault containment is complex. A difficult problem&#8221;

		<description><![CDATA[&#8220;The MHz race (Moore&#8217;s law) just makes the machines faster&#8230; the programs coded 10 yrs ago automatically run faster&#8230;
Additionally, power consumption increases and temperature management is a concern.
Ergo, cost increases with time.
So now, the equation becomes higher computing power = higher power bills= higher costs&#8221;
