how ACCUM works. We are using a text index over XML documents and want to apply a very simple relevance weighting based on occurrences within a certain tag. For example, if TAG1 has a weight of 10, each occurrence in TAG1 should add 10 to the score. We have 13 Tags that should be weighted and multiple occurrences in different tags should be cumulated. So 3 occurrences in TAG1 (weight 10) and one occurence in TAG2 (weight 7) should result in a score of 37.
Just searching in TAG1 works as expected:
( DEFINESCORE( foo, OCCURRENCE ) WITHIN TAG1 ) * 10Three occurrences score 30.
Just searching in TAG2 works also as expected. One occurrence scores 7. However, when I combine both searches
(( DEFINESCORE( foo, OCCURRENCE ) WITHIN TAG1 ) * 10) ACCUM (( DEFINESCORE( foo, OCCURRENCE ) WITHIN TAG2 ) * 7)the score is 61 instead of 37. More interestingly, including all 13 tags (of which most do not contain the search word) lowers the score again.
Have got basic form on a table and have a textarea which holds Notes added by user.
So Notes database field is updated on Save / Apply changes button being pressed.But would really like any text added / appended to the Notes field to be prefixed by userid and date / timestamp.
Is it possible via dynamic actions or Javascript to have any new text added / typed to be auto prefixed as per above.
Would only want the first key press in the filed to trigger the auto-prefix and if added text was deleted then the auto prefix to be deleted as well ?? If user doesn't press Save / Apply changes obviously want to leave existing Notes as is.
I am on Oracle 11.2.0.3 on Linux and have implemented Oracle Text.I created Oracle Text indexes with default setting. However in an oracle white paper I read that the default setting may not be right. Here is the excerpt from the white paper by Roger Ford:URL....(Part of this white paper below....)Index Memory.
As mentioned above, cached $I entries are flushed to disk each time the indexing memory is exhausted. The default index memory at installation is a mere 12MB, which is very low. Users can specify up to 50MB at index creation time, but this is still pretty low. This would be done by a CREATE INDEX statement something like: CREATE INDEX myindex ON mytable(mycol) INDEXTYPE IS ctxsys.context PARAMETERS ('index memory 50M'); Allow index memory settings above 50MB, the CTXSYS user must first increase the value of the MAX_INDEX_MEMORY parameter, like this: begin ctx_ adm. set_ parameter('max_index_memory', '500M'); end; The setting for index memory should never be so high as to cause paging, as this will have a serious effect on indexing speed. On smaller dedicated systems, it is sometimes advantageous to temporarily decrease the amount of memory consumed by the Oracle SGA (for example by decreasing DB_CACHE_SIZE and/or SHARED_POOL_SIZE) during the index creation process.
Once the index has been created, the SGA size can be increased again to improve query performance." (End here from the white paper excerpt)My question is:
1) To apply this procedure (ctx_adm.set_parameter) required me to login as CTXSYS user. Is that right? or can it be avoided and be done from the application schema? This user CTXSYS is locked by default and I had to unlock it. Is that ok to do in production?
2) What is the value that I should use for the max_index_memory should it be 500 mb - my SGA is 2 GB in Dev/ QA and 3GB in production. Also in the index creation what is the value I should set for index memory parameter - I had left that at default but how should I change now? Should it be 50MB as shown in example above?
3) The white paper also refer to rebuilding an index at some interval like once in a month: ALTER INDEX DR$index_name$X REBUILD ONLINE; We are on Oracle 11g and the white paper was written in 2003.
I have a requirement in one of my forms screen.I have a text box(large text area) which should display a help text file when i move my cursor on the topics displayed on the screen.know the code and the properties to be changed in the text box to accommodate large external file text.
I'm new to Oracle Text. I want to implement search for the unique ids. Like google search when the user start typing 123 it need to brings anything starting with 123 and has show like entries how google will shows. When I add number 4 to like 1234 then it has bring numbers starting with 1234.
with the below example I want to insert new translation in a translation table but the NOT IN clause does not work. I have also tried an ANTI-JOIN after reading much about why the NOT IN might not work but the ANTI-JOIN did not work either.The result of the above query is 0 rows inserted. There are about 1000 rows that do already exist and I want to avoid inserting those again. Note, only the Text is the same not the ID or SOURCE.
INSERT INTO T_Translations ( SELECT ID, SOURCE, DOMAIN, TEXT FROM ( SELECT distinct ID, SOURCE, DOMAIN, TransText AS TEXT FROM ( [code]....
I would like to down load and install 11g XE beta but I do not know if it will install and run on my 64 bid Windows machine. I had trouble with the 10 G XE trying to down load it on 64 bits.
If I cannot use it on 64 bits could I make it work if I down load Unbuntu Linux? System info as follows:
OS Name Microsoft Windows 7 Professional Version 6.1.7601 Service Pack 1 Build 7601 Other OS Description Not Available OS Manufacturer Microsoft Corporation System Name XXXXXXXXX (censored) [code]........
i just wanted to know what is the work of owt_text package and as well as owt_util package? this package we have to create in database or its in build packages?
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, nil VARCHAR2, nilce VARCHAR2, nkoy VARCHAR2, cilt VARCHAR2, asira VARCHAR2, sira VARCHAR2, asuba VARCHAR2, kang VARCHAR2, agorev VARCHAR2, [code].......
I have given a specific user default tablespace on Users and a quota 5M. However I want to check if the user have used up 70% of that 5M. If so, I want to increase quota by 500K so in this will be an additional to the 5M. The code I wrote is overwriting the 5M I initially gave the user with 500K. Attached is a sample of the code.
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.
I have table with 4 partition by range partition. I am loading the table in bulk mode to latest partition. Before I load , I dropped the index and after Load I will be creating index. So when I am dropping index, it is dropping index from all the partitions and when creating the index, I am creating the index for all partitions. When I am creating index using local, it is telling you have to create local index for all partitions at the same time. because of that I have to drop and recreate all indexes again. Again I have to gather stats for whole table .
I was thinking we can build index for one partition and index should remain as is for old partitions If this is not the case, how do I plan my load for a partitioned table using bulk mode to latest partition.
I bought Selftestsoftware for 1z0-147 for 9i and 10g. Selftestsoftware is endorsed by Oracle, should be high quality.
But its below sample question and answer seem to be wrong: It says that privilege for subprogram can be granted via role. But from Urman 9i book: the grant the execute privilege must be done explicitly and not through a role.
Did Selftestsoftware made a mistake? Or the question did not mention or assume that the subprogram is based on invoker rights not definer right?
Quote: Question: All users in the HR_EMP role have UPDATE privileges on the EMPLOYEE table. You create the UPDATE_EMPLOYEE procedure. HR_EMP users should only be able to update the EMPLOYEE table using this procedure. Which two statements should you execute? (Choose two.)
GRANT UPDATE ON employee TO hr_emp; GRANT SELECT ON employee to hr_emp; REVOKE UPDATE ON employee FROM hr_emp; REVOKE UPDATE ON employee FROM public; GRANT EXECUTE ON update_employee TO hr_emp;
Explanation: The two statements you should execute are: REVOKE UPDATE ON employee FROM hr_emp; GRANT EXECUTE ON update_employee TO hr_emp;
Unless you are the owner of the PL/SQL construct, you must be granted the EXECUTE object privilege to run it or have the EXECUTE ANY PROCEDURE system privilege. By default, a PL/SQL procedure executes under the security domain of its owner. This means that a user can invoke the procedure without privileges on the procedures underlying objects. To allow HR_EMP users to execute the procedure, you must issue the GRANT EXECUTE ON update_employee TO hr_emp; statement. To prevent HR_EMP users from updating the EMPLOYEE table unless they are using the UPDATE_EMPLOYEE procedure, you must issue the REVOKE UPDATE ON employee FROM hr_emp;
All of the other options are incorrect because they will not meet the specified requirements.
I have created a custom form. I have field called Order No. When i query on Order no.. i should be able to pick order no as well as other fields related to it. how do i acheive this functionality. I mean the f11 and ctrl f11 querying functionality.
