SQL & PL/SQL :: Get_hash_value Generated No Unique Values
May 8, 2012We are using the function dbms_utility.get_hash_value to create a unique identifier, the hash is created based on statement of creating an index. We see that for a different statement is being generated the same value, which in this cause errors because this value must be unique.
The Hash is to be calculated as follows HASH_VALUE = dbms_utility.get_hash_value (sql_text, a 10000)
We are using the correct the hash function or should we use another way to generate unique values?

May 14, 2013We are setting RAC between two machines(Desktop PC connected wirth LAN ....have storage Local to them and no Shared storage..Only NFS).We have shared the mount point by NFS.We do not have any shared storage but we need to share the RAW files to setup the OCR and VOTING DISKS.
The problem is:
1. We need to keep the RAW devices for OCR and voting disk common to the machines (Desktop PC..both Linux OELU5). I am able to create the raw file systems but that is local to one machine. I am not able to understand how to share the raw devices between two machines.
2. Tried to use ISCSI utility but that did not work. (How_to_use_iSCSI_Targets_on_Linux)
Scenario : One Machine has 500 GB Storage. Second machine has 80 GB Storage. Made private and public networks(Used two Network cards in LAN). All are communicating.
Problem : Need to make the storage 300GB (Out of 500 GB) of Machine 1 as shared storage. How can we do that? (Do we need any virtual software...ex .. vmware for that?)

9

i open cursor and fetch these values into variable as shown
OPEN id_search FOR l_sql_stmt;

if l_eve_id != l_eve_id_prev then
l_eve_id_str := l_eve_id_str || ' , ' ||l_eve_id ;
[code].......
but i want only the distinct values in l_eve_id_str , i.e.,
l_eve_id_str := 9,4,7
What this code is doing is creating a string with all the values
l_eve_id_str := 9,4,4,9,7,9,4
How to remove duplicates from this string?

Forms :: Create View Based On Values Selected In Forms
Jun 7, 2013I am working on a simple form which will get the user to fetch required columns of employee master.
For that i have created a form which will display the column names and select option. When user clicks on query, the form will display the selected columns in a block. After going thru if required the user can download it to excel.
As of now I do not have filtering option. For this I thought of creating view based on the selection and then fetch records from the view and display it in form.
To achieve this I would like to know How I create or replace a view dynamically based on values selected. I remember doing this sort of thing long back, but could not recollect it.

SQL & PL/SQL :: Timestamp In Mail Generated From Oracle Is Different
Nov 2, 2012I have found there is a wearied of email generated from my database. I have the data base server located in US (estern time) and the sysdate in the database is AUSTRALIA (AEST). But i am working from India (IST).I have one procedure, which will send email to some recipients once the job is done. It is using UTL_SMTP for sending the email from database.
Now problem is, the email i got from this procedure has a different timestamp which is NOT matching to any of the times:
Time in Mail : 2-Nov-2012 9.56 PM
IST Time : 2-Nov-2012 10.56 AM

Dec 17, 2012As we know that, MV is generating more redo logs during the FAST refresh. but i need more clarifications on that.
see the below examples:
exec dbms_mview.REFRESH ( LIST => 'mv_test', method=>'F');
PL/SQL procedure successfully completed.
select a.name, b.value
from v$statname a, v$mystat b
where a.statistic# = b.statistic#
and a.name = 'redo size';
NAME VALUE
---------------------------------------------------------------- ----------
redo size 147144
see the redo size is 147144 bytes. Immediately, i refreshed in MV view. now there is no update or insert or delete stats happened in source tables. but i do see redo log generation is high for NO DATA refresh.
select a.name, b.value-147144
from v$statname a, v$mystat b
where a.statistic# = b.statistic#
and a.name = 'redo size';
NAME VALUE
---------------------------------------------------------------- ----------
redo size 42352
For no rows refresh, it takes 42352 bytes.. why oracle generated redo logs when there is no DML operations happened in source table.
