Statistic collection question?

You work as a database administrator for Certkiller .com. In your transaction
application, you have scheduled a job to update the optimizer statistics at05:00 pm
every Friday. The job has successfully completed. Which three pieces of information
would you check to confirm that the statistics have been collected? Choose three
A. Average row size
B. Last analyzed date
C.Size of table in bytes
1Z0-042
Actualtests.com - The Power of Knowing
D.Size of table in database blocks
E.Number of free blocks in the free list
F.Number of extents present in the table.

Best practice for statistic collection in 10gR2

Hello,
In Oracle 9i, I had to run every day scripts to calculate statistics.
But in Oracle 10gR2, the collection of statistics has become automatic...I would like some feebback from your experience:
1/ Does it work well?
2/ Do I still need to run my own scripts to calculate statistics as in 9i?
3/ What are the options or parameter to activate to get the best result in 10gR2
4/ Please, give me the best practice to implement the automatic statistic collection in 10gR2
Thanks for your help

Some more question on this topic :
a/ what happens when a empty table is loaded suddenly and there is a query on that...is the statistic calculated at once?no, it would be normal to run dbms_stats manually as part of significant loads
b/ is there any timing for Oracle to launch the statistic collection? the default schedule for maintenance jobs including stats is 10pm - (IIRC) 8am every night and all weekend i.e weeknights and weekends.
c/ is it possible to launch statistic collection only the night when the load is low?see above.

[scjp exam] garbage collection questions

can someone please post me some garbage collection questions + correct answers, because i've taken the SCJP test again and i didn't passed it again. A co-worker of mine also didn't passed either.
(We both got 0% on Garbage Collection every time) And i really thought i had it correct the last time.
So please can someone mail/post me some garbage collection questions? thanks!

The garbage collector collects unreachable objects.
You have no control over when the objects are
collected, but there is a guarantee that all
unreachable objects will be collected before an
OutOfMemoryError is thorwn.Exactly my thoughts...
That's it. It really is just that simple. I scored 94%
on the Programmer's Exam, with 100% in the garbage
collection section.Hmm i got 54% last exam i took. I really begin to doubt about myself, because i find the questions on the exam so tricky.. Last book was Exam Cram (Java), and i found this a very nice and good book to study for the exam. Garbage collection is just one question, so it's either 0% or 100%. So far it hasn't gone anything higher then 0% with me.
Here are some questions:
1. When is the Object first available for garbage
collection (when does it become unreachable)?
Object o = new Object();
Object p = o;
o = null;
p = null;p = null; -> available for gc.
2. When is the Object first available for garbage
collection?
Object o = new Object();
Vector v = new Vector();
v.add(o);
o = null;
v = null;v = null; -> available for gc.
3. Can the Vectors be garbage collected at the end of
this code?
Vector v = new Vector();
Vector w = new Vector();
v.add(w);
w.add(v);
v = null;
w = null;yes
Now i have a question:
public int foo {
Integer result = new Integer(10);
result = null;
return result;
when is result available for gc?

Collection Question - Clearing a computer from one collection to another

Hey Guys,
I have quick question. I have two collection , one for windows 7 and for windows 8.
When adding a computer to my windows 8 collection, can I simply delete
the old object from the windows 7 collection?
Or is there a process for doing this?
Thanks.

Yes, easily. Just go to the collection and you can right click, Membership, and remove the entry there.
You can also open the collection and right click the object and Remove from collection.
If you delete the object you not only lose any membership it had, you also lose its DDR information as well as all inventory information.

1-to-many and collections question

I'm modeling a standard container and container elements relationship using
Kodo.
I'm also trying to be fairly RDBMS efficient, so I'm using the kodo inverse
properties
avoid the extra 'mapping' table.
Here is a simplification:
class Container
private Collection myChildren = new ArrayList();
// + more properties
public Collection getChildren() { return myChildren;}
class ContainerElement
// only have this so Kodo can use reverse property mappings
private Container myParent = null;
// + more properties
public void setParent(Container c) { myParent = c;}
// here is the code snippet from the Container.jdo
<field name="myChildren">
<collection element-type="ContainerElement"/>
<extension vendor-name="kodo" key="inverse"
value="myParent"/>
</field>
Now what I would like to do is this:
Container c = new Container();
c.getChildren().add(new ContainerElement())
c.getChildren().add(new ContainerElement())
and have the parent property automatically set.
Basically the question is:
How can I do Containers through the Coolection APIs, and have the underlying
RDBMS use standard 1-Many by having a parent column?
Thanks for looking into this.

Eivind-
Could I implement my own collection by subclassing AbstractList (or
AbstractSet) that upon add calls the setParent method?The persistent member itself can only be an instance of that custom
List/Set implementation if you implement your own ProxyManager so
Kodo knows how to maintain the proxies for those classes. Take a look
at:
http://www.solarmetric.com/docs/2.4.0/docs/manual.html#com.solarmetric.kodo.ProxyManagerClass
A simpler solution might be to have the class implement
InstanceCallbacks, and then implement jdoPreStore() to ensure that your
relations are set up correctly. E.g.,
public void jdoPreStore ()
// ensure that all the elements of the children collection
// have the proper parent set in the inverse of the relation.
for (Iterator i = myChildren.iterator (); i.hasNext ();
((Child)i.next ()).setParent (this));
Another option is to have your accessor methods just wrap the collection
in a small decorator that does the right thing when elements are added.

Eivind-
It is a common question that people have why their JDO model does not
automatically retain inverse relations in the java model. This is
because that JDO's transparency means that your enhanced classes should
not behave any differently than normal java classes. Thus, it is the
responsibility of the application programmer to ensure that their data
model remains consistent, just as they would have to in a normal,
non-JDO application.
In your case, you could just have a method that deals properly with the
relation. E.g.:
public class Parent
private Collection children = new HashSet ();
public void addToChildren (Child child)
children.add (child);
child.setParent (this).

Large music collection questions...

Hello All,
I am new to iTunes and I have a couple of questions I need answers to before I make a big mess.
I am moving from all windows to all mac environment. My music collection (77,000 songs) exists on several external HDD and are configured for the win 7 machine. The only organization for the collection is my own folder system, it has not been scanned or compiled into a whole by any program, win or mac.
I also have a Mini hard wired to a 2TB TC. I want to get the music into iTunes and I am looking for some direction.
First, I want to clean up the collection and get it all on 1 drive before I move it to iTunes. Or do I? This is my first issue, dont know what to do first. Do I work with the collection in Win first and then move a clean collection into itunes or move it to iTunes first?
I have read about the tuneup program and it seems like it either works great or not. Any opinions here? Of course I am smart enough not to just dump the whole collection on it and expect it to be fluffed and folded in an hour. It is available for Win as well as being an iTunes plug-in... is it better one way or another.
If the opinion is that tuneup is not the best program then what are the better alternatives?
Second question involves final resting place of clean collection. I want to keep the clean collection on an external HDD. Do I want it to be plugged into the mini or the TC for it to be shared accross all devices?
If there is something I am overlooking please chime in, as I said, new to iTunes and Mac and there is a lot to learn.
Thank you for your time in this matter.
Cheers,
Alex

BI data collection question

Dear colleagues,
I have one big question regarding the BI data collection functionality (within the solution reporting tab of T-cd: DSWP).
To whom it may concerned,
According to the SAP tutor located at the learning map,
it looks like SolMan system requires XI installed in order to use the BI data collection. Is this correct? If so, are there any step by step configuration guide that covers from installing XI to enabling the BI data collection function?
Thank you guys in advance.

Hi,
But we want to maintain Item Master in ITEM02, Item Branch in ITEM03 data separate infoobjects because the discriptions always changing that is the reason I created different Master Data infoobject.
Let me give one sample data
Record1: IT001 LOT1 BRAN1 CODE1 CODE2 DS01 DS02 in 2006
Record2: IT001 LOT1 BRAN1 CODE1 CODE2 DS05 DS04 in 2007
If you look at above data in 2006 item description was DS01,DS02 and in 2007 Description changed from DS01, DS02 to DS05,DS04 with the same item no.
We want to maintain item descriptions will be the same in 2006 and 2007 if we change item descriptions in 2007. How can it be possible?
If I go your way how can we achive this task?
Do we need Dalta loads?
Also do i need to create InfoCube? Can I use ITEMNO infoobject as a Data target ?
Please let me know your thoughts.
Regards,
ALEX

Medical Collection Question...

Hello allI have a question to do with medical collection: I ask the billing office of where all the medical bills stem from for charity care. I was asked to send them a letter and explain my situation to them I did and they forgave my debt. The question is The hospital Approval letter says: "Your request for uncompinsated services has been approved 100%. This is a one time benefit. Our assistance program does not cover other providers such as physicans, Anestesiology or Radiology, you may want to discuss this assitance approval with your other providers.". On the bottom of the letter it says blah blah about if you need to appeal there decision, then it says This application for assistance remains on records for 6 months, if you have additional care needs please contact financial counciling for assistance. NO WHERE on this approval does it say from the hospital billing office anything about a 2 yr time frame. When I called the collection agency they even said there isnt dates for deletions of bills and this was in review in the colleciton agency office. They did get sent from the hospital 4 bills which were deleted off report the next week. There are 5 remaining. One of the 4 falls within the 2 yrs that is assumed the only date on this letter is on the top of when they sent it to me June 25, 2015. I called the colleciton agency and told them there was a bill they missed that is on my CR, its dated Sep 2013. They then said they dont see that in there system, I called the hospital and told them of one of the bills, they dont see it either. So I called back the CA and she told me to dispute it with the credit report agencys, I have dont that on the 18th of this month. Of course I opened pandoras box by disputing which the colleciton told me to do, they sent me a bill with 5 collections I owe for the hospital bills. So Because they didnt put a "we will forgive 2 yrs of debt" on the letter or is it automatic with medical collections. All 3 have the disputes in so far havent heard anything on that. Thank you very much. I did upload the letter I was given to equifax

can you plz post the solution.http://www.catb.org/~esr/faqs/smart-questions.html#writewell
How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

Collection questions please advise

Hello everyone, i was was recently reviewing my credit report and see that I have an account that was opened by CO in 2011, as well as a collection (Cavalry portfolio services) for this account that posted from 2013 in the amount of 750. My first questions is that up until recently I have never opened a CO account. Doing some research my wife had one and supposinly I was added as a AU, even though I never had requested. Should I dispute this via the CRA for validation of debt.? If so what are the possible. What've impacts of this? Or what else should I do? My only other collection is held by pinnacle credit services for an old Verizon account that originally defaulted back in 2011, for 758 dollars. They have it reporting on my credit report as opened in 4/2014, which is not the original default date, as mentioned being 2011. From what I read they don't do a DFP and are hard to work with. Can I dispute this with my CRAs as the dates are incorrect? What else would you recommend? I am trying to really boost my credit score, my scores are in my sig. also do I need to worry about any of this resetting the SOL, I'm in NH which is 3 years from my research. Thanks

You can also check out the Rebuilding Forum here: http://ficoforums.myfico.com/t5/Rebuilding-Your-Credit/bd-p/rebuildingcredit If you were an AU (authorized user), you can get that removed from your report (do as RobertEG suggests) as you have no legal obligation to pay it back. However, if you were a joint account holder, you are liable. Does the DoFD (Date of first deliquency) show for the collection? It is 7 years plus 180 days from the DoFD for the collection to fall off. Nothing can change the DoFD. The "wrong" date might just be referring to the date the CA got authority of the collection.

Statistic collection Netflow and SNMP, peak, average

SNMP
We have an Orion device that is collecting via SNMP polls on hundreds of switches and routers. The collection for each device is about once every 15 minutes.
I am wondering how the data is represented on the graph, if the coellection only happens every 15 minutes.
Would the graphing tool just draw straight lines between the points fifteen minutes apart?
For example, if the collection is taken and the interface utilization is at 50% when taken, then utilization shoots up to 100% for fourteen minutes, then goes back down to 50% when the next poll is taken, will I totally miss the period of 100% utilization?
Do routers and switches have any type of SNMP buffer that will show the peaks that can be collected?
Does the "load-interval" comman on the interface affect this at all?
Netflow
We also have all devices sending information to a netflow collector. The collector is showing that the update is every minute.
Do routers and switches constantly send netflow information to the collector in real time?
The routers have top talkers configured on each interface:
ip flow top-talkers
top ten
sort-by bytes
cache-timeout 3600000
My understanding is that the cache-timeout in in milliseconds, which would be an hour.
Does this mean I can do "sh ip flow top-talkers" and the device will not update this information for an hour?
Also, how does this affect the information received ny the collector, if it does?

Create your own collection rule, to mirror the sample times, and what not. Look at the data from your rule vs the mp default rule. It probably has to do with the chart scale imho.

Using a security group to add members to the collection question

Hi,
I have a collection created in SCCM 2007 that is using a security group for membership. So I added a computer to the security group in AD but when I go to SCCM and click on the collection I dont see the computer in the collection. Should it show here or
because it is a security group based membership will it not show the members?
THanks!

Details from Active directory are added to SCCM database through discovery methods. Please ensure that AD security group discovery and AD system discovery are enabled in the primary site. If they are enabled, check the frequency set for these discovery
methods. Once you added these computers to the AD group, you need to wait till the next discovery cycle before it appears in SCCM collections. Till that point, SCCM database will not have information about the group memberships of these computers

JNI / Garbage Collection question

I have a C++ library I am calling into from our application. The question I have is I want the library to return a jintarray or a jstringarray (not sure which yet). If they create that array in the function and then return it to me as the return type, will the Garbage collector automatically free the memory for that array once I am done using it, or do I need to manually free it some how since the array was created in the c code?
Thanks,
Jeffrey Haskovec

Java objects whether they are create in java or JNI are all managed by the VM.

BPM collection question

Hi all,
In BPM collection scenario
Is there any way to capture all the messages ids(inside BPM) which are being sent to that BPM?
Any help will be appreciated.
Regards,
Ivá

Hello Ivan!
Yes. You might specify a WHILE or UNTIL loop inside a block of your BPM process. For example, create a FORK and then create on one path a Receiver Step waiting for a "STOP" message, and in the other fork path create an infinite WHILE step with another Receiver Step to gather the incoming messages (and appending them to a Message List container). Or you can just set a WHILE or UNTIL with a limited amount of messages, without the Fork.
Please check the Help page below for more information about this.
