PL/SQL :: DBMS_STATS.GATHER_DATABASE_STATS / Partition Doesn't Gets Analysed
Mar 20, 2013
If we provide an object filter list in dbms_stats.gather_database_stats specifying the partition name to be analysed , then the partition doesn't gets analysed.The version details are as below
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE 11.2.0.3.0 Production
TNS for Solaris: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 -
ProductionAs already pointed out ,the version 11.2.0.3 is already having a bug for dbms_stats.gather_schema_stats where the object filter list doesn't work.Is this behaviour also a bug ?

what is the difference on DBMS_STATS for table level and partition level , which will provide the best optimizer . If the table xxxx is partitioned from 1 to 10 ,then running gather stats on table xxxx as whole table level or partition level which will provide best result on the performance.

I am running a database version 11.2.0.3 on a RHEL 5.3 system.A nightly ETL job drops all tables of a certain schema and recreates them as part of this job.After recreation of the tables statistics are generated to make query execution faster.
The ETL job uses following statement to gather the statistics for each table: EXEC dbms_stats.gather_table_stats('SCHEMA', 'TABLE', cascade => TRUE); As we had performance issues on the database I analysed the statistics and found that there were no histograms collected for the tables although the data are skewed.
Therefore I searched a database wide parameter where I can change the default statistic collection method from 'SIZE AUTO' to 'SIZE SKEWONLY'. I found following method: DBMS_STATS.SET_DATABASE_PREFS () I used this package to set the database prefs to 'size skewonly' and recreated the statistics. All was fine. exec DBMS_STATS.SET_DATABASE_PREFS (pname=>'METHOD_OPT', pvalue=>'FOR ALL COLUMNS SIZE SKEWONLY');But one day later after the ETL job we had the same issue again. After a further analyse I saw that there were no histograms generated on the tables. It seems that the drop and recreation of the tables make the system wiede default parameter useless.
how to set system wide optimizer defaults even after dropping and recreating a table?

I have a table that partitioned into six partitions. each partitions placed in different table space and every two table space placed it on a different hardisk
when I will do query select with the non-partition keys condition, how the search process ? whether the sequence (scan sequentially from partition 1 to partition 6) or partition in a hardisk is accessed at the same time with other partition in other hardisk. ( in the image, partition 1,4 accessed at the same time with partition 2,5 and 3,6)

I have partition based table one the basis of year month. And we have 8 local indexes on this table. Every month we have to create a new partition and load data into this partition and the volume of the data is around 14million and the load process is taking long time due to indexes. Is it possible to drop the indexes from particular partition?

I am using Oracle 11.2.0.1 Oracle Database.I have a table with 10 Million records and it's a Non Partitioned Table.
1) I would like to partition the table (with partition by range ) without creating new table . I should do it in the existing table itself (not sure DBMS_ REDEFINITION is the only option ) (or) can i use alter table ...?
2) Add one partition which will have data for the unspecified range.

I have the following problem on a 10.2.0.4 Oracle on AIX 1.6..I have 2 RAC nodes as the node # 2 goes down, the VIP migrated correctly to the node # 1, but the listener # 1 do not see the change, and just resolve to the local ip.
The same does not apply in the reverse case, when it drops the node N 1, the listener attends to the fallen VIP node and migrated.The configuration is correct and identical in both nodes, according to the documentation, but I can not find a reasonable answer.

I was working on an applications program It is written in PL/SQL . It is running on an oracle 8i database It was not written by me but now I am responsible of it. I made some changes to database tables for this years regulations. Everything was working fine but yesterday I have recompiled two of the packages for some regulations and one of the procedures was stopped working.
It is called 'sayfa2'. Packages names are 'aday1' and 'aday2'. They both have a procedure called sayfa2 and both of them don't work now. They gave me no compilation errors. All I did is I have copied the original code from toad and compiled it at sqlplus I have changed nothing except some texts inside html tags. I couldn't guess what is wrong.
It actually converts to html pages. All procedures are working fine except sayfa2. aday1 is for to fill information and submit but when I click submit button it gives an error:
The requested URL /pls/kon/aday1.sayfa1 was not found on this server. Oracle HTTP Server Powered by Apache/1.3.19 Server at ...
There is also a problem with Turkish characters they don't appear correctly.
Below is sayfa2 and I also added aday1 package could you have a look at it .
PROCEDURE sayfa2(stuid VARCHAR2,tckimlik VARCHAR2, ad VARCHAR2, ad2 VARCHAR2, soyad VARCHAR2,
sex VARCHAR2, mdurum VARCHAR2, bad VARCHAR2, aad VARCHAR2,
dyer VARCHAR2, dgun VARCHAR2, day VARCHAR2, dyil VARCHAR2,

I have a master block (MASTER with Item 1 and 2) and details block (DETAILS). If the user enters the query mode and queries the Master block, the Details get populated automatically. So far so good.
Now I attached an LOV to Item 1 in the Master Block and the requirement is that when the user picks an item in the LOV, the details should automatically populate. Because of "restricted procedures" (GO_BLOCK) in triggers, I put a Button in a Control Data Block and the code in the WHEN-BUTTON-PRESSED trigger is as follows :
GO_BLOCK('DETAILS');
EXECUTE_QUERY;
It does go to the Details block and also displays all the details. However, when I try to update, insert or delete data, it fails with "Insufficient Privileges". So when I looked at the query being executed (Cntrl + Shift + E), I can see that it is trying to perform these operations on the Master block. (ie for some reason the scope is still in the Master and not Details even after Go_Block(DETAILS) has been executed.
I then tried to use Go_Item('DETAILS.Dept_No') to see if that would work. That too did not work. I tried to set the Navigation Style on these Data Blocks to "Change Data Block". Still no success.

CREATE OR REPLACE PROCEDURE check_values (

/The problem I am facing is in where condition, if I give quoteValues it doesn't fetch me any records when I execute the procedure from sqlplus, but if I am giving my_values it does fetch me records. I am receiving IN parameters like 9856,9712,8723, so first I put single quote around the emp_no and pass that to where condition.

But if i put the RAISE_APPLICATION_ERROR just after this statement and before IF(CONTR_GIOCATORE2 IS NOT NULL AND CONTR_GIOCATORE2 = CONTR_GIOCATORE) THEN, nothing happens after the insert(that goes well) and the trigger doesn't do his job(insert,update etc). if i do that select, i got the no data found, so i put the exception to set the variable CONTR_GIOCATORE2 to NULL.
