New tables & indexes created do not show up in dba_segments view

Dear all,
I have created 3 tables and some indexes, but these objects do not show up in dba_segments view. Is this a normal behaviour? Previously, with dictionary managed tablespace, I can specify the minimum extent to create, when the table/index is created. But I'm not sure how the locally managed tablespace work. Please do advice. Thank you very much in advance.
I'm using Oracle 11g R2 (11.2.0.1.0) for Microsoft Windows (x64), running on Windows 7.
For the purpose of reproducing this issue, I have created the tablespaces as follow:
CREATE TABLESPACE CUST_DATA
DATAFILE 'd:\app\asus\oradata\orcl11gr2\CUST_DATA01.DBF' SIZE 512K
AUTOEXTEND ON NEXT 256K MAXSIZE 2000K
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K
SEGMENT SPACE MANAGEMENT AUTO;
CREATE TABLESPACE CUST_INDX
DATAFILE 'd:\app\asus\oradata\orcl11gr2\CUST_INDX.DBF' SIZE 256K
AUTOEXTEND ON NEXT 128K MAXSIZE 2000K
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K
SEGMENT SPACE MANAGEMENT AUTO;
CREATE TABLE CUSTOMER_MASTER (CUST_ID VARCHAR2 (10),
CUST_NAME VARCHAR2 (30),
EMAIL VARCHAR2 (30),
DOB DATE,
ADD_TYPE CHAR (2) CONSTRAINT CK_ADD_TYPE CHECK (ADD_TYPE IN ('B1','B2','H1','H2')),
CRE_USER VARCHAR2 (5) DEFAULT USER,
CRE_TIME TIMESTAMP (3) DEFAULT SYSTIMESTAMP,
MOD_USER VARCHAR2 (5),
MOD_TIME TIMESTAMP (3),
CONSTRAINT PK_CUSTOMER_MASTER PRIMARY KEY (CUST_ID) USING INDEX TABLESPACE CUST_INDX)
TABLESPACE CUST_DATA;
SQL> SELECT TABLE_NAME, TABLESPACE_NAME
2 FROM USER_TABLES
3 WHERE TABLE_NAME LIKE 'CUST%';
TABLE_NAME TABLESPACE_NAME
CUSTOMER_MASTER CUST_DATA
SQL> SELECT INDEX_NAME, TABLESPACE_NAME
2 FROM USER_INDEXES
3 WHERE TABLE_NAME LIKE '%CUST%';
INDEX_NAME TABLESPACE_NAME
PK_CUSTOMER_MASTER CUST_INDX
SQL> SELECT SEGMENT_NAME, SEGMENT_TYPE, TABLESPACE_NAME, BYTES
2 FROM USER_SEGMENTS;
no rows selected

Prior to 11g, when you created a table or whatever, you automatically allocated one extent.
This is now no longer true and depends on a parameter I don't remember.
dba_segments is a summary of dba_extents.
Obviously, if there is no extent allocated, the table (view is defined with inner join) will not show up.
You could qualify this is as a bug and submit a SR to Oracle. But then the performance impact may be huge.

  • How to check table is creating or not

    Hi,
    I am creating only one table by running a table creation script(table.sql) which contain 366 partition.but I dont know whether table is creating or not.it is taking long time,sometimes I feel like script is hanging.even before running the script I have even spooled but spool file shows nothing. so how to check table is creating or not from background? can anyone please let me know abt this.this is bit urgent
    sql>spool table.log
    sql>@table_partition.sql

    hi,
    I am running the script table_partition which consist of 366 partition and 31 sub partition but the script is hanging.there is no hint in alert log file or anything wat might be the reason is it because of extent size? as extent size for this tablespace where table has to be create is 1mb,wat i suspect is do i need to set for higher value inorder to avoid this?
    with regards;

    I tried to rename a file, it gave me an error message (can't remember the number - 43??) and then the file disappeared from the original folder. When I do a search, the file comes up under the new name, but it does not show a path, and even though preview shows the contents, I can't open the document (Powerpoint) and I can't move the document. I tried "Copy" and paste but it doesn't work. I tried "Share" with Airdrop and iChat, but the file is inaccessible. When i try to rename the file, it says the filename is too long.
    When I try to open it, it says the alias is not good, and asks if I want to fix the alias. I'm afraid to do that and lose all access to this document.
    Right now, it feels like a ghost document - it is on the computer intact, but it is in an undisclosed location and inaccessible.
    Please help!!

    I was able to resolve this by repairing permissions, even though no permissions error was listed specifically for that file.
    I could also have recovered it through Time Machine, but I'm interested in knowing how not to have this happen again!
    I was afraid of rebooting and possibly losing track even of the ghost.
    I did not try EasyFind - I'll keep that in mind next time.
    Thanks for all the comments.

  • Created column not showing in the Document Library View for a Custom Content Type based on Document

    We have a custom content type based of Document Content Type. The OOTB "Created" column does not show up in the view as well as in the Site Settings -> Columns.
    But it shows up in the Display Form and Edit Form of the Item at the bottom "Created at " by " " and "Modified by" at by ""
    Would anyone know how to make this column appear as part of the view ?
    thanks,
    Harsh

    Hi,
    They should by default be possible to add to a view. The only reason they would disappear from the UI if someone has changed the attribute of the Field to hidden = true. You can verify that with PowerShell and if so you can use PowerShell to revert the setting
    to false.
    $w = Get-SPWeb http://dev13$f = $w.Fields.GetFieldByInternalName("Created")$f.Hidden$f.Hidden = $false$f.Update()

    I have added two new extension on CUCM, Directory not showing in attendant console even after resynch on CUCM and attendant cosnole
    Any idea?

    Hello,
    Can you tell us what versions of CUCM and CUxAC you are using?  Just extensions alone in CUCM will not sync to the corporate directory within the attendant console application.  You will at least have to have user's associated with those extensions and depending on your rule set within the console that should then bring those extensions into the console directory.
    Thanks,
    Tony

  • My new mac book air will not show old emails.  how can i fix this problem

    my new mac book air will not show old emails.  how can i fix this problem

    The answer depends on a number of factors, such as the following:
    If you have more than one email account, does this problem affect one, some, or all of your accounts?
    Where did you last see this mail -- in your Inbox(es)? in some other folder(s) outside your Inbox(es)? somewhere else?
    How old is the missing email -- yesterday? just before you got the new computer? over a week? over a month? over a year?
    How are you reading email -- with the builtin Mail application? with some other mail-reading application? with a web browser?
    How do you access your email on the server -- IMAP? POP? Exchange? web browser? other?
    What version of OS X is on your new computer -- Mavericks (10.9.x)? Mountain Lion (10.8.x)?
    Did you migrate your data and applications from your old computer when you set up your new computer?
    For example, if the missing mail is the mail that was in your Inbox before you got the new computer, you are reading it with the builtin Mail via POP, and you failed to migrate data, then the mail was left behind on the old computer. The same would be true if the mail was in "On My Mac" mailboxes and you failed to migrate data.

  • Calendar events not showing up in list view

    Hi,
    some of my events are not showing up in list view. They are synced to the iphone. I can see them in day and month view.
    It seems to me that events created with ical and synced through MM are not showing up, but I'm not sure.
    Any idea?
    Wilfried.

    Yes I have also events from the holidays and the events I created.(Invitations and others) but where is this option for the NC? In general>notifications I can't find anything about showing events from different calendars there. And how is this subscription made because I had the holidays as soon as I input my account on this device. Maybe I included the holiday calendar but I don't remember. How is that made? And where to find these options?

  • Narrative is not showing up in Layout View

    Narrative is not showing up in layout view when I'm creating a custom report. In Step 2, Creating Layout. I am hovering over add view, then down to advanced. Narrative is not showing up. How do I get this to work??? Static text and Legend is not showing either.
    Thank you for your help!!

    Hello,
    You need to have the privilege Analytics Scripting in step 4 for the narrative report to work. Only then would you HTML and javascript you apply on the Narrative report would show up.
    Please update if this works or not.

  • Old All-Day events not showing in Calendar List View

    Reviewing events in my Calendar on the iPhone and have noticed that All Day Events that are older than one year do not show in the "List" view
    For example, I have all my holidays in a calendar called "Vacation". Month and Day view list holidays from earlier than today (09 Sept 2008) properly, however list view shows nothing. Timed events (e.g. day trips) in the same calendar show.
    Similarly no Birthdays appear in the past. I can see a case for Birthdays being omitted in the past, but not other events (e.g. wanting to know exactly when you went to that all day wedding last summer)

    I have this same exact problem. For me, past events that have a specific time associated with them show up in List view; however, past events that are all day events only show in List view once in a blue moon only. Apple support has been absolutely clueless about this issue. They just tell me it's weird and they have no explanation. It's unbelievably annoying though.

    why jdeveloper does not show a correct design view of jsf pages sometimes?
    It does not shows labels and ... , just show tag names like : form , ... ?

    I just closed and open the IDE and page designer shows incorrect pages
    thanks

    Also try this...go to the project properties for the View project. Look at the JSF Libraries and remove the two JSF libraries and then re-add them....this sometimes helps.

  • Calendar items not showing ONLY in list view on iPhone

    Weird: My Calendar items are not showing in the list view only, on iPhone.
    They show when I search, they show in month, they show in Day views--just NOT in list view.
    Ideas?

    I just had the same problem (calendar information--for eight different calendars--OK on laptop and on Mobile me; on the iPhone only 3 of my calendars were displaying in "List" view, but all eight were appearing in "Day" view); first time I've encountered this problem (and immediately after installing the 11-February-2010 iPhone software update, so I'm suspicious that this might have been the cause).
    Solution described in posting immediately above seems to have worked. I.e.,:
    1. shut OFF MobileMe syncing for calendars on the iPhone (from Settings menu);
    2. wait for calendar entries to be removed;
    3. shut off iPhone, and wait 2 minutes;
    4. restart iPhone;
    5. turn ON MobileMe syncing for calendars on the iPhone (again, from Settings menu).
    All eight calendars now appear in List view (and still appear in Day view).
