Difference between swap and tmp

Hi,
I am performing a 11g software installation (11.1.0.7) on HPUX IA64 server.
During the installation, I got this error which says
{code{
Checking available swap space requirements...
Expected result: 39897MB
Actual result: 16384MB
What is swap space? Is it the /tmp space? Do I have to increase /temp space here?
But why is it expecting 39897MB?? (39GB)?? Is there something wrong ?

Dear user!
Swap space isn't the same as temp space. I don't know HPUX but on Linux the swap space is an extra partition where the os may swap parts of your memory on HDD. This happens everytime when you need more physical memory than your machine has. The OS swaps some portion of your physical memory on HDD to free enough space for a new process. Hopefully this should never happen because it breaks down your system performance enormously. The Oracle Universal Installer for Oracle 11.1 demand (physical memory * 1.5) on a Linux system. I think the same happens on HPUX but the factor may not be 1.5 but any other value.
The temp space on the other hand is some space on your HDD where process may create and drop some temporary files.
I hope this is of any help to you.
Yours sincerely
Florian W.

Re: The difference between update() and doFinal() in ClassCipher

Hi Guys,
I found this topic,
The difference between update() and doFinal() in ClassCipher
during a Google Search. I need your help, because I'm working on a project for an university exam.
It's about a Client FTP that sends and received files with the content crypted.
I'm using DES Encryption with "DES/CBC/PKCS5Padding".
I have this doubt: when it's correct to uso the doFinal method? At the last block of the file, or after it? (for encryption)
And during the decryption, how can I use the result of the doFinal operation?

Why is my SSD showing 250mb/s difference between read and write...

So i have recently upgraded to a SSD in my 2011 MBP. 2.4Ghz i5 16Gb RAM. I swapped my HDD with a Samsung 840 Series 250Gb SSD, I noticed a huge speed bump. See attached photos. Read is clocked at 503MB/s peak, and Write is clocked at 260MB/s peak on the SSD. My Question is why is there a 250MB/s difference between read and write?? Using Black Magic Disk Speed test. Mac OS X 10.8.4 Beta.
Thanks

Writes are performed very differently on SSD than they do on a hard drive, and it is common for SSDs to have lower write speeds than reads.
It's actually quite interesting if you're a geek: http://en.wikipedia.org/wiki/Write_amplification
As long as the speeds do match your manufacturer specification for the model (and they do: http://www.samsung.com/us/computer/memory-storage/MZ-7TD250BW ) , there is nothing to be concerned about.

Difference between Null and null?

What is the difference between null and NULL?
When is each used?

There is a null in java, but no NULL. null means no value. However, when assigning value, the following is different:Although the empty String has no special role. Null means, the referential type is not assigned (doesn't refer) to a specific object. The empty String is just another object though, so seeing it or pointing it out as something special when it actually isn't at all (no more special than new Integer(0) or new Object[0]) just adds to the confusion.

Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload
         exporting
              filename                = filename
              filetype                = 'ASC'

              data_tab                = iflatf

Difference between char and varchar, also the difference between varchar2

Hi,
Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
Example 1:
SQL> create table tchar(text1 char(10), text2 varchar2(10))
2 /
Table created.
SQL> insert into tchar values('krystian','krystian')
2 /
1 row created.
SQL> select text1, length(text1), text2, length(text2)
2 from tchar
3 /
TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
krystian 10 krystian 8
Example 2:
create table tvarchar(text varchar(10))
SQL> select table_name,column_name,data_type
2 from user_tab_columns
3 where table_name = 'TVARCHAR'
4 /
TABLE_NAME COLUMN_NAME DATA_TYPE
TVARCHAR TEXT VARCHAR2

The difference between SFP+ and X2

Dear Expert,
I need to know what is the difference between SFP+ and X2! and can I use SFP+ card and module instead of X2?
Thanks,
Mohammad Saeed

Hi,
They are both used for 10Gig interfaces. The difference is the connector type.
SFP+ is LC and X2 is SC.
You can not put an SFP+ into an X2 slot or X2 optic into a SFP+.

Difference between ok_code and sy-ucomm

Hi,
Can any one tell me the difference between ok_code and sy-ucomm

Hi,
Actually OK_CODE and SY-Ucomm are the same. But experts suggest use of OK code for following reason:
In each PAI event that a user triggers by choosing either a pushbutton on the screen or an element in a GUI status, the corresponding function code is placed into the system field SYST-UCOMM or SY-UCOMM and placed in the OK_CODE field (as long as the function code is not empty). Empty function codes are placed in neither the SY-UCOMM field nor the OK_CODE field.
In your ABAP programs, you should work with the OK_CODE field instead of SY-UCOMM. There are two reasons for this: Firstly, the ABAP program has full control over fields declared within it, and secondly, you should never change the value of an ABAP system field. However, you should also always initialize the OK_CODE field in an ABAP program for the following reason:
In the same way that the OK_CODE field in the ABAP program and the system field SY-UCOMM receive the contents of the corresponding screen fields in the PAI event, their contents are also assigned to the OK_CODE screen field and system field SYST-UCOMM in the PBO event. Therefore, you must clear the OK_CODE field in the ABAP program to ensure that the function code of a screen is not already filled in the PBO event with an unwanted value. This is particularly important when the next PAI event can be triggered with an empty function code (for example, using ENTER). Empty function codes do not affect SY-UCOMM or the OK_CODE field, and consequently, the old field contents are transported.

What is difference between abstraction and encapsulation ?

Hi,
I am trying to figure out the difference between abstraction and encapsulation but confused.
Both are used for data hiding then what is the exact difference ?
Thanks.

When you encapsulate something you get an inside and an outside. The outside is the abstraction. It describes how the encapsulated entity behaves viewed from the outside. This is also called the type. Hidden inside is the implementation. It holds detail information about how the type's behaviour is accomplished.
It's a very simplified picture but I think it's quite accurate and it works for me.

What is difference between Iterator and Collection Wrapper?

Hi all,
I dont understand the actual difference between Iterator and Collection Wrapper. I observed both are used for the same purpose. Could any one please let me know when to use Collection Wrapper and when to use Iterator??
Thanks,
Chinnu.

L_Kiryl is right.
Collections support global iteration (through collection->get_next( )) and local iteration (through iterator->get_next( )).
Each collection has a focus object. Initially, the first object has the focus.
Any global iteration moves the focus, which is published by the event FOCUS_CHANGED of the collection.
If you want to iterate on the collection without moving the focus (and without triggering timeconsuming follow-up processes) you can use local iteration. To do so, request an iterator object from the collection and use this to iterate.
And one more advantage of using iterator: it takes care of deleted entities. If you use global iteration then when you reach deleted entity it will be an exception. But there is no exception with iterator in the same situation.

What is difference between modify and update i am using

hi
what is difference between mofify and update
my requiremen is to have three condition checkec while mofifying or updating from a internal table
the three fields are
cus no
status
date these all are primary key in the database table
so which sould i use modify or update
there might be entry already existing in database table or new entry to be created if already existin it should check on the primary keys and updatat if not it should add a record
pls suggest whihc to use and how to implement the check on teh threee primary key
like if modify ztable from table it_test
now where condition ? can be used or not with modify? and if yes how
if not should i use update will update create a new entry if no entry is there and please give syntex
regards
Arora

Hi Nishant Arora,
Modify: It works in performing two actions.
They are: Insert + Update.
For Example If a record that is exited in database, so you are modifying that record, it updates that particular record.
Similarly, If the is not existed in the database, you are modifying it, it inserts a new record.
Update: Update means just it updates the status, I mean it only updates the record. It doesn't inserts any new record if that particular record is not present in the database.
These are the cases you need to write these statements.

What is Difference between SXMB_MONI and SXMB_MONITOR?

what is Difference between SXMB_MONI and SXMB_MONITOR?
Can any explain to this question.please?

Hello,
Both are same.
SXMB_MONI is area menu which will contain all multiple transactions pertaining to monitoring.
SXMB_MONI contains some functions viz monitoring for Bridging, Archived Msgs, Job overview, persistence layer analysis.
SXI_monitor directly leads to the message monitoring for the IS, which is part of the SXMB_MONI.
SXI_MONITOR directly executes the monitoring report.
