Granularity of statistics to collect (only pertinent if the table is partitioned).
'ALL' - gathers all (subpartition, partition, and global) statistics
'AUTO'- determines the granularity based on the partitioning type. This is the default value.
'DEFAULT' - gathers global and partition-level statistics. This option is obsolete, and while currently supported, it is included in the documentation for legacy reasons only. You should use the 'GLOBAL AND PARTITION' for this functionality. Note that the default value is now 'AUTO'.
'GLOBAL' - gathers global statistics
'GLOBAL AND PARTITION' - gathers the global and partition level statistics. No subpartition level statistics are gathered even if it is a composite partitioned object.

After truncation space not reclaiming

HI,
During our health check we found one of the tables in our database occupying more than 11 GB of space. We got approval from APP team to truncate the table.
And i truncated accordingly.
But after truncation also the table is still showing the same size.
I checked the record count. it's showing ZERO records.
Could you please let me know why my database behaving like this?

Your question is not very clear.
This query deletes rows in table t1 only if there is a matching row in table t2 for key_value1 and key_value2 and if t1 rowid is lower then t2 rowid: only rows in t1 are deleted (no rows in t2 are deleted).
Since rowid are generated internally by Oracle and encode datafile number, object identifier and row number, I'm not sure it makes really sense to compare them in 2 differents tables just "lower than " operator. However it could be useful to use comparison on some rowid fields if you use DBMS_ROWID package to compare datafile number, object_number and row number.

Table.rows.find() returns null in a table where the row exists.

Hi...
I am working in a Project in Visual Studio 2013 where I have to read an Excel report related with a list of business opportunities. Some of the Fields that are involved in it are: Opportunity ID, BU, Account, close date, Account Manager,
Total Value and so on. As soon as I get the conection with the Excel Report, I fill a DataTable and declare the columns [Opportunity ID] and [BU] as my Primary Keys. In that way, an Opportunity value may have one o more rows
with different BU code each of them. In consequence, you can define one row in the table if you specify the [Opportunity ID] and the [BU] values.
My problem starts when I try to get information of those rows that have an specific value of [Opportunity ID]. For that situation I make a "foreach" structure where I check the BU codes that are involved with that Opportunity. So
I use the Find() Method to get the information of the row specified by the Opportunity ID and BU. The first time it goes to find the information it gets the results successfully but in the next cycle changing just the [BU] using the same [Opportunity
ID] value, the find() method returns a "null" and I do not know why because I am sure that the row exists in the table. I have verified the "Unique" property for the [Opportunity ID] and [BU] columns (which are
my primary keys) and they are in false which is OK.
I share the code that I am using...
Hope someone can help.
Thanks.
Alfmar.
void ObtenTotalesxBUs(string Opportunity, string[] BUs, Object[] TotalBUs, Object[] ExpTotalBUs)
ArrayList TotalesBUs = new ArrayList(); //Required information from the row.
ArrayList ExpTotalesBUs = new ArrayList(); //Required information from the row.
foreach(string businessUnit in BUs)
Object[] LlaveBusqueda = { Opportunity, businessUnit }; //Provide values to the Primary Keys.
DataRow RenglonInfo = null;
RenglonInfo = TablaFunnel.Tabla.Rows.Find(LlaveBusqueda); //Find method receives the Primary Keys values. Here is where I have a "null" in return the second time changing just the [BU] field.
TotalesBUs.Add(RenglonInfo["Total"]); //Get the required information from the row.
ExpTotalesBUs.Add(RenglonInfo["Expected Total Value"]); //Get the required information from the row.
TotalBUs = TotalesBUs.ToArray();
ExpTotalBUs = ExpTotalesBUs.ToArray();}

Hi Viorel..
Thanks a lot for you help.
I am absolutely sure that the second ítem of BU is valid and exist in the table because I tried to make a "Select" statement in the table providing the values of [Opportunity ID] and [BU] and I get the expected record. So, why is not
working using Find() with the defined Primary Keys???
I tried this in order to test that the record exists...
if(RenglonInfo == null)
string strSelect = "[Opportunity ID] = '0000218256' AND [BU] = 'SFW'";
RenglonInfo2 = TablaFunnel.Tabla.Select(strSelect);

Creating new row right after popup opens (JBO-35007 because of trigger)

Hi,
I have the same popup (with an ADF form) to add and to edit data. But i have two buttons which displays this popup - Add new and Edit, Edit works OK, on add, i insert new record like this:
        DCIteratorBinding dciter =
            (DCIteratorBinding)bindingContainer.get(iterator);
        ViewObject view = dciter.getViewObject();
        Row newRow = view.createRow();
        view.insertRow(newRow);
        view.setCurrentRow(newRow);before popup is open. And it adds a new record. But the record has id -10 (or some other negative number). This -10 is shown on calling page (the page from which the popup is open) in ADF ReadOnly table as -10 as id and other cells in row empty. That shouldn't happen (se bellow why). User then edits empty form in popup, and commits - then i get JBO-35007 because -10 changed to 123 - because of trigger.
I tried to requery - it doesn't help, see Refresh after pop-up window closes.
Can you suggest a solution on how to create a row right after popup opens?
Also,
i create new record on button's LaunchListener method. This method seems to execute before popup is open and so it affects the calling page also. I think the problem would be solved if new row would be created after popup is opened, not while opening it. (clicking create in popup works fine)

in my real case, i usually don't show ids; but to simplify debugging, i created test project where i show as many things as possible.
you mean, creating new record like following?
        bindings.getOperationBinding("Create").execute();I don't use that because i don't get empty fields in popup window (although new record is created). Actually, i don't know how to set this created record to be selected one. Suggestions?
And I did some more testing, if I create new record with clicking on Create (not creating new row automatically), i get JBO-35007 only if there was selected any other than the first row in table.
and i tried to move create method binding in pagedef, so it's the first one.. But it seems like there is no effect.
btw, i found this in one of examples on web:
   <invokeAction Binds="Execute"
                  id="refreshTableViewObjectAfterAddingNewApp"
                  Refresh="prepareModel"
                  RefreshCondition="#{processScope.addedNewApp}" />refresh condition must be true when adding new row and false for everything else. I'm not sure what that does, but it seems to work... :)
I really shouldn't use the same View Objects in popup and 'master' page, should I?

PLEASE HELP?>>>

Hi George,
What do you mean by, when you claim that the page still runs without your VO (i.e. Just the PG & AM)? Does it means that your webBeans in the page that references the VO Attributes, still comesup with no issues like (VO not found)?
If yes, then your jdev. project is picking up the VO xml/class files else where from your classpath. Please check your classpath settings and library settings to see where the old file is still available.

Re-claim of space after truncating mview logs

Hi All,
We have truncated mview logs on the environment.
Logically freespace(dba_free_space) 250 gb is available, But Physically we did not get any space.
For reclaim physical space what can i do?
Thanks

Hi Bai ,
Thanks for gud support,
Sorry for delay...
I will explain clearly so that u can understand the prob
Before truncating the mview logs avalable free space(dba_free_space) is --
SQL> select sum(BYTES)/1024/1024/1024 from dba_free_space;
SUM(BYTES)/1024/1024/1024
39.0560455
After truncating the mview logs available free space is ---
SQL> select sum(BYTES)/1024/1024/1024 from dba_free_space;
SUM(BYTES)/1024/1024/1024
251.980179
And these are the spaces cosumed by the tables corresponding tablespace...

Commiting 3 new rows - only 2 exist after

Hi OTN,
in my ADF BC application I have a bounded taskflow for creating new rows.
It contains CreateInsert operations for VO1 and VO2 (VO2 is a child of VO1 and a child of another VO which is not touched by the taskflow). I've put postChanges between those operations so no temporary keys are there - the keys are generated via DB triggers.
After those operations another bounded taskflow is called which contains CreateInsert for VO3 (VO3 is a child of VO1) and a form where Commit is called.
After Commit I navigate to a test page which shows three forms representing VO1, VO2 and VO3. The page shows me that each of three new rows was created - I see them (with the real key valyes) in the forms.
But in database only two new rows appeared. VO1 and VO3 (tables) have new rows, but no new row appeared in VO2 table. The form on a test page showed me a VO2 row which really didn't exist.
Why is there no new row in one of tables?
I use only one ApplicationModule.
VO2 is a standard VO based on an entity. It is updatable.
No errors in logfile.
I how absolutely NO idea, why does it happen.
Would love to hear an advice.
Thanks.
JDev 11.1.1.3

Hi,
if VO2 is dependent on VO1, when you create a new row in VO how to do you ensure its getting committe before VO2 gets committed ? Did you set the composite flag on the association between the two ? Another solution to handle this synchronization - to avoid constraint validations - is documented in the Fusion developer guide

Hi Suchita,
Thanks for your quick response.
Actually we have not done any enhancements to the BTADMINH context node. we have enhaced the CRMD_ORDERADM_H table using the EEWB fields. After this I have checked the component BT115H_SLSO/view to provide the value help for the fields, the Zclass was automatically assinged to the Context and Page attribute remained same for BTADMINH.
I have checked in the SE24, the class does not exists. I have created a copy of CL_BT115H_S_DETAILS_CN00 as ZL_BT115H_S_DETAILS_CN00 and assigned to BTADMINH and Page attributes of the same view. After I have opened the Web UI, the following exceptions are occured:

Space is not released after truncating the table

Hello,
Yes space wont be released immediately .If large extents are in picture which I assume is your case it goes into deferred drop a background process which will execute after some time( time may vary).See below link for details.
As per BOL if extents are more than 128 it goes in deferred drop.
http://msdn.microsoft.com/en-us/library/ms177495.aspx
You should wait for some time .keep checking the free space
Below discussion will surely help you in understanding.See Jonathan's reply

Sequence of begin/end blocks.Delete only if updated.Updte only if row exist

Here is a sequence of events I need to perform.
1) I need to update a table with the systime for a given id.
2) Commit (so that the systime is stored before I delete)
3) Once updated, delete row from that table for the given id so that the row moves to the audit table with the updated systime - added in step 2.
For this I need to keep the following things in mind:
a) Update only if that particular id (passed as IN parameter to the SP) exists. That is validate existence before updating/deleting.
Here are questions ralted to the above scenario:
1) How is this kind of validation usuallty performed?
2) Update and delete will be in 2 separate begin exception end block?
Example
begin
    begin
    update...
       commit
    exception
       rollback
    end;
delete...
commit
exception
rollbacl
endHowever if update fails for some reason, I do not wish to come to the delete option.
How can I take care of that?

The reason why I commit after doing the update is so that when I delete, what I have updated goes to the audit table.But that would only be necessary if it was a seperate session trying to read the data.
If you update data on a table then your own session will see that data at existing on the table whether you have committed it or not, whilst other sessions will only see that data once it is committed.
A commit should be issued when it logically makes sense, not just to try and ensure that the data is on the table for yourself.
What would happen if you update some data, commit it, someone else reads it in their session and then you go and delete it? They have read your updated data whereas if they do a read before you delete then it's more logical that they should have read the pre-updated data.
It seems like you are trying to incorporate more steps than are necessary to perform a simple task.
