Happy Muleeeee
Imagine you are integrating one app to another app and more app is there. The integration point is hetero gen one to another application. One application provide flat file, while the other use web service, another one provide DB read only (view) for the integration point (we called it end point).
So, to handle this kind of situation two approach can use
1. Develop application and do formatting as per integration point.
2. Use ESB to do handle this.
Mule is one of the open source ESB dan provide community Edition and Enterprise Edition.
Here is the sample that I made in Mule Designer to integrate .Net (REST API) endpoint with Java (cxf API).
Using Community Edition
Misal Nama Table yang kita mau audit adalah table M_PRICE dan kita mau mengaudit setiap ada activity Add, Update and Delete terhadadap table ini.
Kita perlu 2 table untuk mengaudit, satu untuk mencatat data2 yang diubah (tracking), satu table lagi digunakan untuk mencatat summary sudah berapa kali berubah master table tersebut.
M_PRICE ==> master table
M_PRICE_A ==> Audit table
M_PRICE_C ==> tracking berapa kali berubah
Dan berikut Triger yang bisa kita buat dengan nama M_PRICE_T
create or replace
TRIGGER M_PRICE_T BEFORE INSERT OR DELETE OR UPDATE ON M_PRICE FOR EACH ROW
DECLARE
l_change_num NUMBER;
BEGIN
— Increment the change_num for this table and keep the new value
UPDATE M_PRICE_C set change_num = change_num+1 returning change_num into l_change_num;
– Insert appropriate audit row(s)
IF INSERTING THEN
INSERT INTO M_PRICE_A(PRICE_ID, PRICE_NAME, change_num, aud_action, aud_timestamp) VALUES(:new.PRICE_ID, :new.PRICE_NAME, l_change_num, ‘I’, SYSDATE);
ELSIF UPDATING THEN
INSERT INTO M_PRICE_A(PRICE_ID, PRICE_NAME, change_num, aud_action, aud_timestamp) VALUES(:new.PRICE_ID, :new.PRICE_NAME, l_change_num, ‘AU’, SYSDATE);
INSERT INTO M_PRICE_A(PRICE_ID, PRICE_NAME, change_num, aud_action, aud_timestamp) VALUES(:old.PRICE_ID, : old.PRICE_NAME, l_change_num, ‘BU’, SYSDATE);
ELSE
INSERT INTO M_PRICE_A(PRICE_ID, PRICE_NAME, change_num, aud_action, aud_timestamp) VALUES(:old.PRICE_ID, : old.PRICE_NAME, l_change_num, ‘D’, SYSDATE);
END IF;
END M_PRICE_T;
Here is the query
SELECT a.sid,a.serial#, a.username,c.os_user_name,a.terminal,
b.object_id,substr(b.object_name,1,40) object_name
from v$session a, dba_objects b, v$locked_object c
where a.sid = c.session_id
and b.object_id = c.object_id
1. create the script to find files older than 30 days and delete the files, suppose the script file name is deletefile
can use this
find /home/mujoko/archive/ -mtime +30 -exec rm {} \; // find files the older than 30 days in /home/mujoko/archive/ folder, make sure there is space after rm and before {}
or
find /home/mujoko/archive/ -mtime +30 |xarsg rm // using this script its possible we face error too many parameters if the files is to many to delete
2. Login as root
3. Configure crontab by execute
crontab -e mujoko //replace mujoko by your own username
4. Edit crontab by adding
30 1 * * * /home/mujoko/deletefile //deletefile is the file you create at step 1
5. Save your crontab.
Walaaaa, your file within /home/mujoko/archive will be deleted when the files is older than 30 days.
You will see some commands which start with a colon (:). These commands are ex commands which are used by the ex editor. ex is the true editor which lies underneath vi — in other words, vi is the interface for the ex editor.
Entering Text
To begin entering text in an empty file, you must first change from the command mode to the insert mode. To do this, type the letter i. When you start typing, anything you type will be entered into the file. Type a few short lines and hit Return at the end of each of line. Unlike word processors, vi does not use word wrap. It will break a line at the edge of the screen. If you make a mistake, you can use the Backspace key to remove your errors. If the Backspace key doesn’t work properly on your system, try using the Ctrl h key combination.
Cursor Movement
You must be in command mode if you wish to move the cursor to another position in your file. If you’ve just finished typing text, you’re still in insert mode and will need to press ESC to return to the command mode.
Moving One Character at a Time
Try using your direction keys to move up, down, left and right in your file. Sometimes, you may find that the direction keys don’t work. If that is the case, to move the cursor one character at the time, you may use the h, j, k, and l keys. These keys move you in the following directions:
h left one space l right one space
j down one space k up one space
If you move the cursor as far as you can in any direction, you may see a screen flash or hear a beep.
Moving among Words and Lines
While these four keys (or your direction keys) can move you just about anywhere you want to go in your file, there are some shortcut keys that you can use to move a little more quickly through a document. To move more quickly among words, you might use the following:
w moves the cursor forward one word
b moves the cursor backward one word (if in the middle of a
word, b will move you to the beginning of the current word).
e moves to the end of a word.
To build on this further, you can precede these commands with a number for greater movement. For example, 5w would move you forward five words; 12b would move you backwards twelve words. [You can also use numbers with the commands mentioned earlier. For example, 5j would move you down 5 characters.]
Command Keys and Case
You will find when using vi that lower case and upper case command keys are interpreted differently. For example, when using the lower case w, b, and e commands, words will be defined by a space or a punctuation mark. On the other hand, W, B, and E commands may be used to move between words also, but these commands ignore punctuation.
Shortcuts
Two short cuts for moving quickly on a line include the $ and the 0 (zero) keys. The $ key will move you to the end of a line, while the 0 will move you quickly to the beginning of a line.
Screen Movement
To move the cursor to a line within your current screen use the following keys:
H moves the cursor to the top line of the screen.
M moves the cursor to the middle line of the screen.
L moves the cursor to the last line of the screen.
To scroll through the file and see other screens use:
ctrl-f scrolls down one screen
ctrl-b scrolls up one screen
ctrl-u scrolls up a half a screen
ctrl-d scrolls down a half a screen
Two other useful commands for moving quickly from one end to the other of a document are G to move to the end of the file and 1G to move to the beginning of the file. If you precede G with a number, you can move to a specific line in the document (e.g. 15G would move you to line 15).
Moving by Searching
One method for moving quickly to a particular spot in your file is to search for specific text. When you are in command mode, type a / followed the text you wish to search for. When you press Return, the cursor will move to the first incidence of that string of text. You can repeat the search by typing n or search in a backwards direction by using N.
Basic Editing
To issue editing commands, you must be in command mode. As mentioned before, commands will be interpreted differently depending upon whether they are issued in lower or upper case. Also, many of the editing commands can be preceded by a number to indicate a repetition of the command.
Deleting (or Cutting) Characters, Words, and Lines
To delete a character, first place your cursor on that character. Then, you may use any of the following commands:
x deletes the character under the cursor.
X deletes the character to the left of your cursor.
dw deletes from the character selected to the end of the word.
dd deletes all the current line.
D deletes from the current character to the end of the line.
Preceding the command with a number will delete multiple characters. For example, 10x will delete the character selected and the next 9 characters; 10X will delete the 10 characters to the left of the currently selected character. The command 5dw will delete 5 words, while 4dd deletes four lines.
Pasting Text using Put
Often, when you delete or cut text, you may wish to reinsert it in another location of the document. The Put command will paste in the last portion of text that was deleted since deleted text is stored in a buffer. To use this command, place the cursor where you wish the deleted text to appear. Then use p to reinsert the text. If you are inserting a line or paragraph use the lower case p to insert on the line below the cursor or upper case P to place in on the line above the cursor.
Copying Text with Yank
If you wish to make a duplicate copy of existing text, you may use the yank and put commands to accomplish this function. Yank copies the selected text into a buffer and holds it until another yank or deletion occurs. Yank is usually used in combination with a word or line object such as the ones shown below:
yw copies a word into a buffer (7yw copies 7 words)
yy copies a line into a buffer (3yy will copy 3 lines)
Once the desired text is yanked, place the cursor in the spot in which you wish to insert the text and then use the put command (p for line below or P for line above) to insert the contents of the buffer.
Replacing or Changing Characters, Words, and Lines
When you are using the following commands to replace text, you will be put temporarily into insert mode so that you can change a character, word, line, or paragraph of text.
r replaces the current character with the next character you enter/type.
Once you enter the character you are returned to command mode.
R puts you in overtype mode until you hit ESC which will then return
you to command mode.
cw changes and replaces the current word with text that you type. A dollar
sign marks the end of the text you’re changing. Pressing ESC when you
finish will return you to command mode.
Inserting Text
If you wish to insert new text in a line, first position the cursor to the right of where you wish the inserted text to appear. Type i to get into insert mode and then type in the desired text (note that the text is inserted before the cursor). Press ESC to return to command mode.
Inserting a Blank Line
To insert a blank line below the line your cursor is currently located on, use the o key and then hit ESC to return to the command mode . Use O to insert a line above the line the cursor is located on.
Appending Text
You can use the append command to add text at any place in your file. Append (a) works very much like Insert (i) except that it insert text after the cursor rather than before it. Append is probably used most often for adding text to the end of a line. Simply place your cursor where you wish to append text and press a. Once you’ve finished appending, press ESC to go back to command mode.
Joining Lines
Since vi does not use automatic word wrap, it is not unusual in editing lines to end up with lines that are too short and that might be improved if joined together. To do this, place your cursor on the first line to be joined and type J. As with other commands, you can precede J with a number to join multiple lines (4J joins 4 lines).
Undoing
Be sure to remember this command. When you make a mistake you can undo it. DO NOT move the cursor from the line where you made the change. Then try using one of the following two commands:
u undoes the last change you made anywhere in the file. Using u again
will “undo the undo”.
U undoes all recent changes to the current line. You can not have moved
from the line to recover the original line.
Closing and Saving Files
When you edit a file in vi, you are actually editing a copy of the file rather than the original. The following sections describe methods you might use when closing a file, quitting vi, or both.
Quitting and Saving a File
The command ZZ (notice that it is in uppercase) will allow you to quit vi and save the edits made to a file. You will then return to a Unix prompt. Note that you can also use the following commands:
:w to save your file but not quit vi (this is good to do periodically in
case of machine crash!).
:q to quit if you haven’t made any edits.
:wq to quit and save edits (basically the same as ZZ).
Quitting without Saving Edits
Sometimes, when you create a mess (when you first start using vi this is easy to do!) you may wish to erase all edits made to the file and either start over or quit. To do this, you can choose from the following two commands:
:e! reads the original file back in so that you can start over.
:q! wipes out all edits and allows you to exit from vi.
More about Combining Commands, Objects, and Numbers
Now that you’ve learned some basic vi commands you might wish to expand your skills by trying some fancy combination steps. Some commands are generally used in combination with a text object. We’ve already seen some examples of this. For example, when you use the command dw to delete a word, that combines the delete (d) command with the word (w) text object. When you wish to delete multiple words, you might add a number to this combination. If you wished to delete 2 words you might use 2dw or d2w. Either of these combinations would work. So, as you can see, the general format for a command can be
(number) (command) (text object) or (command) (number) (text object)
You might wish to try out some of the following combinations of commands and objects:
Command Text Object
d (delete) w (word to the left)
y (yank/copy) b (word to the right or backward)
c (change) e (end of word)
H (top of the screen)
L (bottom of the screen)
M (middle of the screen)
0 (zero – first character on a line)
$ (end of a line)
( (previous sentence)
) (next sentence)
[ (previous section)
] (next section)
Repeating a Command
If you are doing repetitive editing, you may wish to use the same command over and over. vi will allow you to use the dot (.) to repeat the last basic command you issued. If for example, you wished to deleted several lines, you could use dd and then . (dot) in quick succession to delete a few lines.
A Quick Word about Customizing Your vi Environment
There are several options that you can set from within vi that can affect how you use vi. For example, one option allows you to set a right margin that will then force vi to automatically wrap your lines as you type. To do this, you would use a variation of the :set command. The :set command can be used to change various options in vi. In the example just described, you could, while still in vi, type :set wrapmargin=10 to specify that you wish to have a right margin of 10. Another useful option is :set number. This command causes vi to display line numbers in the file you are working on.
Other Options
To view a listing of other options, you could type :set all. To view only those options which are currently in effect, you can type set: by itself. Options that you set while in a vi session will apply during that session only. To make permanent changes to your vi environment, you could edit your .exrc file. However, you should not edit this file unless you know what you are doing!
