Is it true about ASO

Hi All,
Is it true that write back functionality for ASO is available from 9.3.1???? Does it NOT have write back before that??

CL wrote:
Are you stuck on 9.2? I can remember Tim Tow demoing ASO writeback with Dodeca before Hyperion had it. I think the trick was Dodeca caught the send event, created a text file, and loaded that to Essbase. That is exactly what we did in those versions. The 'official' writeback now in Essbase does, I believe, something similar, but I understand that it writes back to a slice instead of to the whole cube. Apparently, loading data into an ASO database causes the entire file to be written. We noted that in our implementation and recommended that customers talk with us regarding their usage patterns before implementation as large scale writebacks would have been problematic due to the way that ASO dataloads work. The Smart Slice efforts (and their related APIs) are probably a result of the desires of the public to writeback to massive databases (ie ASO)..
BTW, the customers who wanted to writeback to ASO have all upgraded and we have since intentionally disabled that functionality as the 'official' writeback is a better, though not an ideal, solution.
Thoughts anyone?

True about updates through a view

hi frds
i just need the right answer for the choices mentioned below with explanation
plz help me
What is true about updates through a view?
A. You cannot update a view with group functions.
B. When you update a view group functions are automatically computed.
C. When you update a view only the constraints on the underlying table will be in effect.
D. When you update a view the constraints on the views always override the constraints on the underlying tables.

And a very tricky only it is.
Peter, you are correct that view constraints are not enforced in the sense of PKs and FKS, but there are two other view constraints that are enforced.
SQL> CREATE TABLE t AS

1 row updated.The WITH READ ONLY constraint bars all changes to the view. The WITH CHECK OPTION stops any changes that would make the record invisible to the view. It is essentially a CHECK constraint on the view.

Is this true about PS2 devices?

I just got a new computer. I don't know a lot about hardware, etc.
The Mainboard I got is an MSI K8N Neo4 S 939
My PS2 devices are not working and the guy who sold me the computer told me that by unplugging the mouse and keyboard while the system was running, I may have shorted out the board.
Is this true?

Quote from: MGP on 18-December-05, 13:04:44
It is possible that you shorted the keyboard controller, generally you can hot swap keyboard and mouse but some MB like the NEO versions are very sensitive to
I take it by your post that none of your PS2 ports are working, if this is the case then I would guess that the PS2 controller on the MB is shot.
So... if I have indeed shot my PS2 controller on the MB, what can be done? Is this repairable? Do you think it could potentially cause other problems for me? I am using USB devices now but am concerned about future problems due to this happening.
Also, do you think this should be covered under the 1 year warranty the shop gave me?
Thanks,

Is it true about iphone 5?

i just heard some rumours about iphone 5 and i just wanna know if its true of not?!

True, I didn't read the whole agreement, I happened to have scrolled to the bottom and read the last three words (at 5.3), thus I realised it wouldn't matter what anything above said anyway.
So, to summerise the 'agreement' for you:

Is it True about SQLPLUS ?

Based on below link :
http://intermediatesql.com/index.php/tools/sqlplus-might-show-incorrect-explain-plan/
SQLPlus, while a useful tool, has its own share of problems that you need to be aware of ?
Any Idea is very appreciated.
Thanks.

Interesting article. I left a nice long comment on that blog article. :-)
P. Forstmann, thanks for the link to the documentation - I think that Tom Kyte covered this limitation well in his books and in a couple of AskTom articles, but it was helpful to be able to be able to quote the documentation.
My comment attached to the blog article follows:
Please note that what you have reported in this blog article is in fact NOT a bug in SQL*Plus. Behind the scenes, SQL*Plus' AUTOTRACE facility uses an EXPLAIN PLAN FOR call to retrieve the execution plan for a submitted SQL statement. All bind variables for a call to EXPLAIN PLAN, whether called from SQL*Plus or another utility, are interpretted as VARCHAR2 (regardless of the actual bind variable data type) and are not initialized with a value (this also prevents bind variable peeking from affecting the execution plan). The Oracle Database documentation states the following about EXPLAIN PLAN: "Oracle does not support EXPLAIN PLAN for statements performing implicit type conversion of date bind variables. With bind variables in general, the EXPLAIN PLAN output might not represent the real execution plan."
Your article states that it is attempting to compare execution plans for NUMBER and CHAR binds, but the VC bind variable is actually defined as a VARCHAR2 and not a CHAR.
A quick demonstration:
CREATE TABLE T1 (C1 NUMBER, PRIMARY KEY(C1));
INSERT INTO T1
SELECT ROWNUM FROM DUAL CONNECT BY LEVEL<=100;
COMMIT;
EXEC DBMS_STATS.GATHER_TABLE_STATS(OWNNAME=>USER,TABNAME=>'T1',CASCADE=>TRUE)We now have a very simple table with a primary key index, and 100 rows in the table. On to the test:
VARIABLE N1 NUMBER
EXEC :N1:=1
ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 12';
SET AUTOTRACE ON
SELECT
C1
FROM
T1
WHERE
C1 = :N1;
Execution Plan
Plan hash value: 2546125981
| Id | Operation         | Name         | Rows | Bytes | Cost (%CPU)| Time     |
|   0 | SELECT STATEMENT |              |     1 |     3 |     0   (0)| 00:00:01 |
|* 1 | INDEX UNIQUE SCAN| SYS_C0028425 |     1 |     3 |     0   (0)| 00:00:01 |
Predicate Information (identified by operation id):
   1 - access("C1"=TO_NUMBER(:N1))
SET AUTOTRACE OFFNotice the Predicate Information section of the execution plan shows that the N1 bind variable is being converted from a VARCHAR2 to a NUMBER for the comparison. That conversion is a direct result of AUTOTRACE using EXPLAIN PLAN to generate the excution plan for the SQL statement. Now, let's take a look at the way to display the actual execution plan (in Oracle Database 10.1 and greater):
SELECT
C1
FROM
T1
WHERE
C1 = :N1;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR(NULL,NULL,'TYPICAL'));
PLAN_TABLE_OUTPUT
SQL_ID d2fjtd39f9gmd, child number 0
SELECT   C1 FROM   T1 WHERE   C1 = :N1
Plan hash value: 2546125981
| Id | Operation         | Name         | Rows | Bytes | Cost (%CPU)|
|   0 | SELECT STATEMENT |              |       |       |     1 (100)|
|* 1 | INDEX UNIQUE SCAN| SYS_C0028425 |     1 |     3 |     0   (0)|
Predicate Information (identified by operation id):
   1 - access("C1"=:N1)Notice in the above, the Predicate Information section does not show that the N1 bind variable is being converted from a VARCHAR2 to a NUMBER for the comparison.
Now that we are finished with the 10046 trace, we should disable it:
ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT OFF';Still not sure that SQL*Plus just calls EXPLAIN PLAN when AUTOTRACE is enabled? Take a look in the 10046 trace file that was generated, below is a small portion of the trace file:
PARSING IN CURSOR #11 len=85 dep=0 uid=286 oct=3 lid=286 tim=178896871268 hv=3595065010 ad='4697a6750' sqlid='gkgsxamb4hppk'
EXPLAIN PLAN SET STATEMENT_ID='PLUS702067' FOR SELECT
C1
FROM
T1
WHERE
C1 = :N1
END OF STMT
PARSE #11:c=0,e=144,p=0,cr=0,cu=0,mis=1,r=0,dep=0,og=1,plh=0,tim=178896871268
BINDS #11:
Bind#0
oacdty=01 mxl=32(00) mxlc=00 mal=00 scl=00 pre=00
oacflg=00 fl2=1010000 frm=01 csi=178 siz=32 off=0
kxsbbbfp=1f533240 bln=32 avl=00 flg=05Notice in the above the call to EXPLAIN PLAN, that the oacdty is set to 01 (VARCHAR2), and that the bind variable's value was not submitted.
Of course, it is also possible for TKPROF to show the wrong (Row Source Operation) execution plan for a query, but that is a topic for another discussion.
If anyone cares to see a case where the Row Source Operation execution plan may be displayed incorrectly, you will find a test case here:

Is this true about Trade Ins?

I called my local Best Buy and the rep told me that the trade in phone had to be originally purchased at Best Buy? Does anyone know if this is true?

Hello BRIVAEH226-
There are city, county and state regulations that do control what we can take as a trade-in. In some situations, we are required by those regulations to only take trade-ins that can be validated as purchased in a Best Buy store by the customer producing a Best Buy receipt.
This is why all of our trade-in promotions as well as our Limitations and Restrictions of our trade-in program here call out that some stores may have additional limitations that prevent a trade-in. Your local store should be able to provide you with more information around any particular regulations that they have to follow.

Is this true about installation disks??

Is it true that certian OS cd's can only be loaded onto certain Mac's? Ex. Like a installation disk from a emac wont work on a powermac? What do the codes on the disks mean when it says "disk 1" and "disk 2" etc? I aquired a 2002 powermac G4 quicksilver and need to reinstall but dont have the disks. How will I be able to tell which installation disks to buy If i'm looking to install Tiger??
-Thanks for your help

funylinks2004, welcome to Apple Discussions.
Tiger install DVDs are in short supply. Tiger is no longer available at the Apple Store but is still available for $129 by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753). For other sources, do a Google search for MA453Z/A and M9639Z/A . Also look on eBay. Be sure & buy a retail version (black with silver X) and not a model specific version (gray).

If you really mean compulsively flipping the switch, all hardware switches have a finite lifetime designed for rational use and you may eventually break it.

The true amount is the higher of the two, in this case.
Finder and Disk Utility will often show differing quantity of free space for the following reason.... If Time Machine is turned "on" in Lion, Time Machine will accumulate copies of changed information and store it as "Local Backups". This affords more "restore points" for your Time machine backups than would otherwise be kept if Time machine were to only create restoration points at each syncing to your backup drive. These "local Backups" are purged from the system at each backup sync, and the process of accumulation begins anew.
The operating system treats these local backup files as "low priority", and will be erased straight away, if ever during normal operation the user needs this disk space. Hence, some reports will not count these files at all in free space calculations, while others recognize the space as at least temporarily in use.
As well, Local Backups will stop accumulating is the free space drops below 10% of total. This is so that paging operations are completely unhindered by what might be a situation where erasure may be required before virtual memory could issue a write operation.
You can turn "local Backups" off via a terminal command, but it is hardly necessary. You can stop the accumulation and purge (erase) the files by simply by turing off Time Machine, and then using the "backup now" feature the next time you want to sync to your Time Machine backup drive. You simply will have no additional staged backup points other than the ones you make every time you sync. In other words, it will be just like it was in Snow Leopard, except that you have to "tell" Time Machine to sync, instead of TM doing it automatically just by hooking up the drive. Turning off Time machine doesn't disable TM, it simply turns off Local Backups, and automatic syncing upon backup disk mounting .

(f) An object inherits its variables and methods from its class
(g) An object inherits its variables and methods from its class and its superclasses
(h) The variables and methods of a class are defined in its objects
(i) The variables and methods of an object are defined in its class
(j) The variables, variable values and methods of an object are given in its class

(a) A class is made of objects - true
(b) A class is a collection of objects - true
(c) A class supplies or delivers objects to the rest of the application - true
(d) A class is used as a template to create objects - true

A class is a not collection of objects. A class not only contains objects
A class represents objects and others.

Is it true about the new 21.5" iMac

that the RAM can't be upgraded after purchase? Also I've heard that it comes with a 5400 RPM hard drive, but when I went to to the website I couldn't find out if it was possible to order it with a 7200 RPM drive.

Then, you've not been listening to Apple's gurus. Jobs started it and Cook and Phil Schiller are mouthing the same things. See http://techland.time.com/2012/10/26/apples-phil-schiller-on-the-state-of-the-mac / for example.
Apple wants everyone to waste resources pushing everything digital, to and from the cloud, including the iTunes and Mac Apple Store. Don't you know that's the new way. As for thinness, all they did is shrink the edges, but who cares since the display is only a 2-D thing and an inch or two narrower means nothing. Just marketing hype and keeping users out of their computers.
