Dba-tab - Can't See Any Histogram On TAB 1 In Schema Browser?
Jun 13, 2013
If a table and several columns are listed in dba_tab_histograms does this mean that the table 100% certain has a histogram or more?
select * from dba_tab_histogramsAND table_name='tab1';
OWNER TABLE_NAME COLUMN_NAME ENDPOINT_NUMBER ENDPOINT_VALUE ENDPOINT_ACTUAL_VALUE
---------- ------------------------------ ------------------------- --------------- -------------- --------------------------------------------------
USR TAB1 COL1 0 3.0002E+
USR TAB1 COL1 0 5.0661E+35
USR TAB1 COL1 0 200062635
USR TAB1 COL1 0 2456436.95
USR TAB1 COL1 1 1.1002E+10
USR TAB1 COL1 1 2.3720E+35
USR TAB1 COL1 1 230082138
USR TAB1 COL1 1 1236436.95
In Toad I can't see any historgram on TAB1 in the schema browser.. Running Oracle 11.2 on Linux.. Question:If a table with columns are "in" dba_tab_historgarms does this actually mean that there are a histogram on the tables/column?

We are playing with Toad 9.7 and seems like the right tools for Trade. The schema browser on left hand side I am keeping on Multi Tab type.The one problem is that when I select Table or Constraint from there, the tabs rearrange and is quite annoying to find another tab say View again since it has changed its location.
Is there any way to keep the TABS fixed to their location so when you select no changing of their position occur.

I'm trying to collect histograms for column COL_C of table TAB_A(150K records), So an index "BAD_IDX" will *not* be used in a query when the value is not selective.
This is my query:
SELECT COL_A, COL_B , COL_C , COL_D , COL_E , COL_F
FROM TAB_A
WHERE COL_A = 050
AND COL_B = 13012345
AND COL_C = 0
AND COL_D = 0
AND COL_D >= '07/23/2013 00:00:00'
ORDER BY COL_E ASC;
Now, I have index "BAD_IDX" on columns (COL_C, COL_E ).and the distribution of values looks like this:
select COL_C, count(*)
FROM TAB_A --very not selective for 0, selective for the rest, also no histogram
group by rollup(COL_C)
order by 2 desc;
and the result is 20k row long (20k distincts), So I'll post just the top part of it:
COL_CCOUNT(*)
-------------
158382
086356
695583772
623044169
659558964
680045564
689664263
[code]...
Now, the problem with the query was that "COL_B = 13012345" was the most selective predicate, And an index for it did not exist, so the index "BAD_IDX" is used, and is scanning 86k records (all the "0" value records for column COL_C)!
So, I created an index
Create index GOOD_IDX on TAB_A(COL_B) compute statistics;
However, that BAD_IDX index is still being used! I've thought that maybe it's because the lack of histograms for the column COL_C.I've also understood from documentation I've read that the suitable histogram type is TOP FREQUENCY, Because although I have 20k distincts here for the column COL_C, what does the difference is the 86k records of value 0.
I try to create histograms for the column:
BEGIN
DBMS_STATS.GATHER_TABLE_STATS (
ownname => 'ANDREY'
, tabname => 'TAB_A'
, method_opt => 'FOR COLUMNS COL_C'
);
END;
/
But then when I check - I see that
1. My query is still using the wrong index
2. My histogram is height-balanced and not FREQUENCY
select histogram from dba_tab_columns where table_name='TAB_A' and column_name='COL_C' and owner=user;
The result is:
HISTOGRAM
----------
HEIGHT BALANCED
What do I need to do in order to
1. Make my query use the correct index
2. Create a FREQUENCY histogram

When I click on 'Run Form', the Applet is not opening in Internet Explorer.
Giving Error like " Internet Explorer has encountered a problem and needs to close. We are sorry for the inconvenience."
Even I have re-installed the oracle 10g the same problem is coming.
Note: When I remove jinitiator and then reinstall jinitiator the applet is opening once and again if I run the form second time the same above error is coming.

I have a list box that is populated from a record group using a WHEN-NEW-FORM trigger. When I run the form this displays fine when the list box is set as Poplist or Tlist, but when I change this to combo box and run the form it doesn't load properly in the browser (a blank screen followed by the background a a toolbar that says window).

When I try to run the form by clicking Program/Run form, it opens a webpage(explorer) and displays ?ORACLE FORMS? label, but does not show the form only blank screen appear. When I try to run the form by clicking Program/Run form, it opens a webpage(Firefox), but does not show the form only blank screen appear.
I have noticed that in Start OC4J Instance it has some thing like as below:
SYSDATE TIME FormsServlet init():
configFileName: E:DevSuiteHome_2/forms/server/formsweb.cfg
testMode: false
pop-ups is not blocked in my browser I have allow active content to run in files on your computer.directory name (where the form is stored) also doesn't contain any spaces.
Also I have change the
baseHTMLjinitiator=basejini.htm
to this
baseHTMLjinitiator=basejpi.htm.
I have done all the things mention in this forum to overcome this error.But, still the same problem is there.Also please take a note that I am using JRE not JINITIATOR. Beacuse when I am using the JINITIATOR it give me the problem of browser crash in both IE and firefox.Also I am using Windows XP and oracle form 10g.

I have a table with about 15-20 constraints and when I look up the tables constraints in SQL workshop, I can only see 10 constraints. Not sure if its a bug or I need to configure something, somewhere to make it show alll my constraints. I can see all constraints by querying the user_constraints view.

I have problems with calling procedure directly from webbrowser. I have a procedure test in test_pkg package. I granted execute on it to anonymous , added it to wwv_flow_epg_include_mod_local function and still have error 404.searched this forum and found this: Does listener use wwv_flow_epg_include_mod_local
So I granted to apex_public_user and created synonym for him to my package. And it starts working. But then I wanted to add next proceudre to my package the same way, and change my test procedure and it stop working again. Now I have 404 error again.

We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.
