Add new records to the table while ESX online
Hello
I want to add some new drives in a RAID 5 Array existing VMFS-store of data running on my Fibre Channel SAN, on which there is already a logic unit number.
Can I add these discs with no problems so my 2 ESX hosts are online, and access to the existing database
Objective final is to inreasing the size of the array by creating another logic unit number with the freespace added and then creating a new data store
Thanks in advance,
Alessandro
It depends on your San. If that supports the extension line of a RAID set, you'll have no problems. But you need to enlarge the VMFS data store later. As far as I know, this is not possible with ESX 3.5. As single VMFS partition is allowed per LUN think about presenting the new disk as a new LUN space.
You can add this new LUN as an extension to the VMFS data existing store to get this one expanded.
Another solution would be to remove all the guests of the existing VMFS (if you Storage VMotion which can be done online), destroy that one and create a larger on the expanded LUN.

Add new records to the table of the ADF
Hello
I use Jdev 11.1.1.3.0.
I have a Page of the ADF with detail Table of form - master, I want to add new records to the table reflecting in DB. Is it possible to do? pointers or demo?
Thank you
MBWhat are the components are used in your table? When you created the table originally, you specified as a table read-only? If your table contains components of af: outputText, then you will need either manually change components entry way, or remove the table and re-drop-the-in the form of table (not read-only)

Add new data to the table in a log file
Hi all. I am new to Oracle and I need to also write new data table in a logfile on Linux in order to live in the display screen. My first thought was to write a trigger, and after some research on googled around, I finally came to this:
create or replace trigger foo_insert
After Insert on foo
for each line
declare
f utl_file.file_type;
s VARCHAR2 (255);
Start
s: =: new.udate | '-' || : new.time | ' ' || : new.foo | ' ' || : new.bar | ' ' || : new.xyzzy | ' ' || : new.frobozz | ' ' || : new.quux | ' ' || : new.wombat;
f: = utl_file.fopen ('BLAH_BLAH', 'current.log', ' a');
UTL_FILE.put_line (f, s);
UTL_FILE.fclose (f);
end foo_insert;
It seems properly to add new data in the log file as new inserts occur, but open and close the file each time are of course not optimal.
In the app real new lines could have inserted every second or two. How can I optimize it? In addition, the log file will be archived and turned every day, so there must be a way to effectively report the relaxation of the oracle to reopen the case.
Thank you!>
I would like to pursue the optimization of the trigger
>
As Ed suggested you need to think this through a few others and refine the requirements.You said "I am new to Oracle. So you may not realize that anything a trigger didn't REALLY EVEN HAPPEN! The transaction can still be restored by Oracle or by the appellant. Want that all the 'hiccups' look too? If this isn't the case, then you can not use a trigger to do this. You need the process that translates the trigger being called to do logging after the data is stored.
It should be noted that this requirement is before we can offer solutions to a problem.
Assuming you want the trigger record all attempts change the data, then the best way I know to do that is to minimize the work does the trigger.
Another fundamental principle is to follow the advice of the Ed and have a clear separation and distinction between "what" should be done and 'how' to do it.To minimize the trigger work change proposed Nicosa approach. Create an AUTONOMOUS_TRANSACTION stored procedure that handles the 'how' and just have the trigger to transfer data to the stored procedure values. The trigger provides data; He doesn't know, or care, what is done with the data.
The stored procedure is then free to use the files, a table, write to a file or any other method is proving to be the best. You can change the methods without affecting the trigger.
A queue or table may contain data, but again once you need to think about the obligation. Do you need fair access to data only once? Now, you want a "tail". But what happens if this requirement change tomorrow? You won't have to redesign the architecture.
With a queue once you delete the queue data it won't here later if you want to get it again. With a table you can take as long as you want.
I would like to start by using a table to store the data. If you use a sequence number or "insert_date" value, you can always query the data of interest. The table just collects data. He does not care how to use data.
So, by using proven design principles and knowing that the requirements are for the most part unknown and may change unexpectedly, I would be:
1. create an AUTONOMOUS_TRANSACTION stored procedure that accepts the parameter data and the thicket in a simple logging table.
2. change your trigger to call the procedure to step #1
3. create another procedure that performs a query of 'tail' for you will depend on 'insert_date' number or sequence. This query can write data to a file or return a cursor ref that your script can use to provide data for display.The approach described above takes each step in the process relatively independent of the other stages.
Until put you the finishing touches to the requirements that you do not want to lock up your initial design.

create new record in the table of the tree
REFERRED to the ADF Code 83 corner. How-to - create the two-way synchronization between a tree and a form input element
Mr.Frank usese (deptId) of allDepartmentsWithEmployeesIterator-> > > iterator
to insert the new employee in the service selected tree node
it get the departmentId for the current line of allDepartmentsWithEmployeesIterator
and set it as the new employee to the new departmentId inserted in the allEmployeesIterator
This multiy in table tree we have the employees table and departments table
------------------------------------
public String onCreateEmployee() {} BindingContainer links = getBindings(); OperationBinding operationBinding = bindings.getOperationBinding ("Create1"); Object result = operationBinding.execute (); If (! operationBinding.getErrors () .isEmpty ()) {} TODO add the error handling Returns a null value. } a department Id the value of the tree node's parent DCIteratorBinding = departmentIter (DCIteratorBinding) bindings.get ("allDepartmentsWithEmployeesIterator"); Line currentDepartmentRow = departmentIter.getCurrentRow (); Object deptId = currentDepartmentRow.getAttribute ("DepartmentId"); DCIteratorBinding = employeesIter (DCIteratorBinding) bindings.get ("allEmployeesIterator"); Line currentEmployeeRow = employeesIter.getCurrentRow (); currentEmployeeRow.setAttribute ("DepartmentId", deptId); Returns a null value. } -----------------------------------
I'm doing the same functionalty
in the same tree table
Insert the child registered under the selected parent node
but it gives me the ID of the employee of topRank
in which case we use tree one View object
as long as same as in ADF code corner article
032. creating a table tree of a single object View and access selected lines
We thus obtain the topRanked EmployeeID Steven King is 100
not the employeeId correct if you select low-tier employee
------------------------------
Create Itried to use with the parameter
He gave me the same result always it create used under top class used 100 steven King
not covered by the selected Manager
-----------------------------------------
in a few words I'm looking for a way to insert a new line under the selected node
in the case of the component tree is based on the same view object
is it an idea or a help on this
Hello
in your case, the employee Id is what you need to get the tree component itself. In my article, I rely on the synchronization between two iterators, which in your case is not possible. If access you the component of the tree to get the current selected node. This should be an instance of JUCtrlHierNodeBinding that you can call getRow to obtain the selected user. You can query a second View object to show the employee to edit (the current together by key line). Even when you create a new employee. Access you the second VO iterator used after you call Create to create a new line. On the iterator, you call iterator.setAttribute (attribute_name, value_read_from_parent)

When I try to insert several records with the seq.nextval it gives error
violation of primary key.

Concerning
Mr President.
I find the solution by creating a function before the triiger
as below
CREATE SEQUENCE "ALIZA"."SL_CUSTOMERS_SEQ" MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 1 NOCACHE NOORDER NOCYCLE ; CREATE OR REPLACE FUNCTION get_SL_CUSTOMERS_vId RETURN VARCHAR2 AS BEGIN RETURN SL_CUSTOMERS_SEQ.NEXTVAL; END; / CREATE OR REPLACE TRIGGER SL_CUSTOMERS_TRG BEFORE INSERT ON "ALIZA"."SL_CUSTOMERS" FOR EACH ROW DECLARE dummy VARCHAR2(200); BEGIN dummy := get_SL_CUSTOMERS_vId(); :NEW.CUSTOMER_ID := dummy; END; /
It works very well
Thank you all for the suggestions.

Failed to add new detail in the form of master detail record
Hello
I created a simple database application from scratch by selecting the start a page master detail. This has generated a report (for the parent) and a page of form (for the child). On using the form to add a new record to the child, the following error is generated:
Internal error in the routine mru: ORA-20001: error in MRU: line = 1, ORA-01400: cannot insert NULL into ("Student" 1.) "" DELEGATE. " "" ""DELEGATE_ID"), insert"Student"1." DELEGATE values' ('DELEGATE_ID', 'CLIENT_ID', 'NAME', 'INITIAL', 'SEX', "SPECIAL_NEEDS") (: b1,: b2,: b3: b4,: b5,: b6)
Error failed to process the update.
The field 'child' in the error message is automatically hidden on the form and I guess on the generation of this form using the wizard I would have had the opportunity to link the field delegate_id to a trigger or a sequence like this seems to happen when you create a scratch from application database using other types of page. I'm new to Apex then I would be grateful if someone could let me know why this default behavior occurs.
Kind regards
Kevin.I tried for Apex 4.0.2 (my version) and 4.1 (on apex.oracle.com) and I'm wondering for the production of main PK and details in both versions.
What are your steps exactly in the wizard? Like this?
Create page-> form-> form detailed Master
Now you see a list of steps sub whose "Source of primary key.Oh I see "Create an Application Assistant." in your message. Start with an empty application (blank page) and use the wizard to create a Page. Maybe it's the difference.

Unable to add a new column to the table of the LCD? Option, just usually add it.
I have a form of LCD with a table in it. Im trying to simply add a new column to the table. The option is there, but the column appear just after clicking Add the column to the left. I selected a column, right click the space > insert > column to the left. But the habit intsert. The object table properties tab shows lines and colum numbers, but they are grey.
See screenshots:
http://www.emermed.NET/staging/forums...
http://www.emermed.NET/staging/forums...
It is a dynamic array, where a new line can be inserted using a button. Is that the dynamic nature of the question? ID hate to cancel all the flow dynamics and programming just to add a column, and then reapply them all.
Thank you!Hello
You do not add the columns in the object > palette (screenshot 2) of the Table. I suspect that the problem is that it is not enough on the page (in the content area) to add the column. In the screenshot 1, if you look at the width of the column highlighted from the space to the right of the table, you will see that a column can be added due to restrictions of space.
Reduce the width of the column highlighted (temporarily), and then add a column. Once added, you can resize the columns to match the width of the page.
Hope that helps,
Niall

Inserting a new record in the database using a form empty ADF
Hello
I'm trying to insert a new record into the database using a form.
I have an Employee table and its corresponding entity object and the view object. The table has an id that is used as the primary key and is filled using a sequence in the comic book.
Data controls, I dragged and dropped at the sight of the employee as a form of ADF and checked the submit button include. Then I dragged and dropped the validation on submit button operation.
When I connect to the app and go to the page used to create, I have 2 problems:
1 - the form is filled with the logged in user info.
2. If I try to change the news and validation, the user info is changed in the database and no new record is created.
It makes a little sense to me, but I would like to know if there is a way around it (get an empty form and insert a new record).
NB: the employee id is not part of the form, I want to be filled using the sequence.
Kind regards
MBUser, please tell us your jdev version!
To do this, you must create a new record before going to the display of the form page. In a stubborn workflow (btf), you drag the operation createInsert of the VO on the btf and it will generate a link method, add a view to the btf and put a navigation of the binding of the method of the page. Mark the method as 'Activity by default'. Now, ren, you call the workflow, you create a new record that will show your blank form.

in writing the new value to the table, do not change the scroll position
I have a program that writes a new value to a chart of every minute. (The x axis is time). I show the last weeks of a data value in the graph, but I also axis scroll bar visible so that users can scroll back to see the previous weeks. The problem is that if they have scrolls in a few weeks and the graphical update of one minute that happens, the graph jumps at the present time (week last of the watch). Is it possible to have the table simply stay put even when when a new value is written for her?
John,
I believe you can use the property of 'Reporter Panel updated' to achieve this. Set the property to TRUE on a mouse of the user enter event of the chart in order to prevent the update of the table while the user moves the scroll. Set it to false on mouse leave. I tried the same thing with a mouse to the bottom/mouse event, but it does not behave as expected. You can PLAY autour with different events to see what works the best, but this basic technique should work. Take a look at the attached screenshot for details.

Query took too much time when adding new column to the table and the index set on this
I added a new column to the table that contains thousands of records. and created the composite index with three columns (those newly added + two existing column)
for the specifics. TBL table there are two columns col1, col2
I added the new column col3 to TBL and created composit index (col1, col2, col3).
Now for all the records in col3 is NULL. When I choose on this table, it takes too long...
Any idea what my I do bad., I have check the query plan, it is using the index
It is solved using collection of statistics using the
