What is the real difference between the following procedures in the DBMS_STATS package:GATHER_SYSTEM_STATS
GATHER_DICTIONARY_STATS
GATHER_SYSTEM_STATS: System statistics to describe the characteristics of the system hardware, such as i/o and CPU performance and utilization of the query optimizer. When choosing an execution plan, the optimizer evaluates necessary IO and CPU resources for each request. Statistics system helps the query optimizer estimate the costs of IO and CPU, allowing the query optimizer to choose a best execution more accurately plan.

* Original title: upgrade
I want to upgrade to a newer Windows operating system Windows Vista Home Pro 64-bit. What is the recommended procedure? I see that Windows 7 or 8, a free update to Windows 10 is offered. Should I buy 7 or 8 then you spend 10 or just buy 10?
Thank you
Jim
Hello
Depends on hardware configuration required on later operating systems, and also find out if the manufacturer of the laptop computer is supported and provides drivers for operating systems later as to whether it is possible or feasible to upgrade or not.
There is no free upgrade Vista to 7, 8.1, or 10.
Follow these steps before you buy Windows 7.
Microsoft sells more than 7; Try Amazon.com.
Go to your computer / computer laptop manufacturer Web site and see if Windows 7 drivers are available for your make and model computer / laptop.
If this is not available, Windows 7 will not properly work for you.
Run the "Windows 7 Upgrade Advisor.

What is the real difference between the card and the ORDER of the member functions?
Hi all
According to the documentation http://docs.oracle.com/cd/B28359_01/appdev.111/b28371/adobjbas.htm#CHDFGJFB
Control methods make comparisons of direct one-to-one object. Unlike the methods of the card, they cannot determine the agenda of a number of objects. They simply tell you that the current object is equal or less than the object that it is being compared, based on the criterion used.
A method of control is a function of an object (
SELF
), with a declared parameter that is an object of the same type. The method should return a negative number, zero, or a positive number. This value means that the object (the implied no saidSELF
parameter) is less than, equal, or greater than the declared parameter object.I still can't find all the differences between them. Because the documentation said that makle methods to ORDER one to an object comparisons. However, you can also do it with the map member function the (as illustrated below). Can someone clarify this please?
create rectangular type is object
(
number of width,
number of height,
Order member function camparison (r rectangular) return number
);create or replace type rectangular body is
order member function camparison (r rectangular)
Return number
is
Start
If (self.width + self.height) > (r.width and r.height) then
Return 1;
elsif (self.width + self.height) < (r.width and r.height) then
Returns - 1;
on the other
return 0;
end if;
end;
end;OR
create or replace the rectangular type is object
(
number of width,
number of height,
card camparison return number of member function
);create or replace type rectangular body is
map member function camparison
Return number
is
Start
Return self.width + self.height;
end;
end;For the two I use the following block of code right? So, what is the difference?
Set serveroutput on;
declare
rectangular rect1;
rectangular rect2;
Startrect1: rectangular = (3, 5);
rect2: rectangular = (4, 8);If rect1 > rect2 then
dbms_output.put_line ('rect1 Büyük');
on the other
dbms_output.put_line ('Büyük rect2');
end if;end;
My 2nd question is: in the function member order what is the parameter reference? When we compared how it corresponds to?
camparison of Member (rectangular r) function order
When comparing the two objects is the function parameter is the object of the comparison sign right?
If rect1 > rect2 then
Thanks in advance
Order compare 2 objects.
Card returns a value that can be used to control any number of objects.

What is the correct procedure of DMBS_XPLAN for the query execution plan
Hello.
We are on Oracle 11.2.0.3 on Linux. I am dev. DBA and we have about 80 developers Java development team. They want to question the execution plan of queries to resolve the sqls. Generally, they use the GUI tools like the toad to see execution plan. I always use the procedure for the following query execution plan:
Select * from
Table (dbms_xplan.display_cursor (null, null, 'allstats + cost'));I should suggest that they use this too rather than rely on tools like the toad - because they can show estimated plan and not the actual plan. And to provide a sql, it is best to use the real plan to work with. Do not take account of 'allstats + cost' part in the command above, but my point is: should I ask them of still rely on sqlplus and not the GUI tools and use the command display_cursor package DBMS_XPLAN?
I will be grateful for suggestions.
OrauserN
You must use the DBMS_XPLAN package and functionality.
The tool used to run the package doesn't matter. A raw request to DISPLAY_CURSOR will run the same server code in any tool including Toad.
If you rely on other GUI features (for example a "explain plan" button or similar) then you know what this feature of actuall application running under-the-covers.
My suggestion would be to assess and consider using Oracle free sql developer version 4 because it is not only FREE but also uses the DBMS_XPLAN correctly.

It would be awesome if someone can explain to me what oracle does internally when we run the above procedure. I understand that I wrote the dictionary in the redo logs. I am trying to understand:
(1) where did the oracle read (including system tables)?
(2) applications in house turns to write the dictionary for redo logs.
Kind regards

Difference between function and procedure
Hi all
My doubt is that the procedure can be used to return multiple values with OUT parameter and function can also be used to do the same if necessary to return multiple values with OUT parameter.
So with this point of view, which is maybe the difference between these types of the two objects. and obviously if necessary to choose one of these two, we'll go to procedure, why not function?
What is perhaps the reason for this?
Thanks in advance.
Kind regards

To the best of my knowledge this last statement is not correct.
The main difference for procedures and functions it program design.
A procedure should be used for something that is running a process, where nothing is required to be returned.
A function should be used when a value is required to be returned.Yes, the procedures can have OUT parameters (as can functions) but that is generally considered bad practice. If you have values be returned, you must use a function with an appropriate return type (structured type if necessary) so that all the requirements of data is returned via the return value. IMO the only acceptable practice to use variables is when you use a variable IN OUT for something in a procedure for this element which is manipulated by the procedure, so for example you'd 'ManipulateData (myData); as a procedure rather than "myData: = ManipulateData (myData);" in function, where the latter would be using resources of additional memory (copies of data) in most cases.

Differences between process and procedures
Hi all
can someone tell me what are the differences between the processes and procedures? Is there a difference between a process with only automatic spots and a procedure?If your process dynamically invokes a procedure and your process and procedure called dynamically are in the same project, it will work when it is deployed to the Studio and business.
However, if your process tries to dynamically call a procedure from another project, you're going to collide in a bug (the null pointer you get). Support may disagree, but on the company dynamically invoke a procedure of a process in a single project via an interface procedure must initiate a procedure in another project successfully if both are deployed on the same engine of the company.
Suggest that you report it to the Support. If you need a simple project that duplicates the problem, here is a zip file which has two projects. A project is a process that dynamically calls a procedure through an interface. The invoked procedure is in the other project in the zip file.
http://www.4shared.com/file/182416607/9e9763a4/InvokeProcedureInDifferentProj.html
This is a project that works and that invokes a procedure successfully when the process and the invoked procedure are both in the same project.
