RAC & Failsafe :: How To Implement Non-RAC
Jan 12, 2013
We have an Implementation of Non-RAC (Single Instance with Existing ASM-RAC as storage) and below is the Details,
The client have a Real Application Cluster configuration on their AIX Server from there Data Center and they want to implement a Single instance Database that will used ASM as Storage and the storage or Disk that they want to use is the same Disk or Mirror copy of the Disk from their RAC Database.
Scenario:
-The AIX Server that they have is a one-way Hardware Mirroring (PPRC) only and it is not designed to run a 24/7 activity.
-DATAGUARD is not an option.

SQL> CREATE OR REPLACE TRIGGER TRI_ABOVE_JOINTBOX
2 BEFORE UPDATE ON JOINT_BOX FOR EACH ROW
3 DECLARE
4 PRAGMA autonomous_transaction;
5 BEGIN
6 IF (:NEW.SCALE_X <> :OLD.SCALE_X) OR
7 (:NEW.SCALE_Y <> :OLD.SCALE_Y) THEN
[code]....
The above code is for the GIS project. When I am trying to implement the above trigger it is giving output in such a way that the joint box(which is point feature in the designed database) scale is fixed to 1 as written in the code,but it cannot be moved in the DGN(front end),this is because trigger is fired before update.
Actual intention is that the feature(joint box) need to move in the DGN then the trigger need to be fired so that then scale need to fixed to one even after changing.For that I implemented after update trigger in the above code,but then it is throwing error as
ORA-04084: cannot change NEW values for this trigger type. I guess this is because after update trigger cannot be implemented for bind variables old and new.
1.joint box can move in DGN(this can be acheived automatically if after implementing after update trigger).
2.after dragging in the DGN the scale to be fixed as 1.

SQL Loader - How to implement/Best solution.
I have 3 tables with their columns:
- MASTER_TABLE - MASTER_ID, DATA;
- PARENT_TABLE_A - MASTER_ID, DATA;
- PARENT_TABLE_B - MASTER_ID, DATA.
And the file I need to import has lines like the ones below:
MMMASTER_TABLE1
PAPARENT_TABLE_A1
PBPARENT_TABLE_B1
MMMASTER_TABLE2
PAPARENT_TABLE_A2
PBPARENT_TABLE_B2
MMMASTER_TABLE3
PAPARENT_TABLE_A3
PBPARENT_TABLE_B3
The line means:
- 1 - M or P: indicates which table to insert: MASTER or PARENT;
- 2 - M or A or B: indicates MASTER, PARENT_A, PARENT_B;
- 3:18 - DATA.
Based on the values above, what I need to do is:
1. Load a line to MASTER_TABLE;
2. Load a line to PARENT_TABLE_A pointing to its relative line in MASTER_TABLE;
3. Load a line to PARENT_TABLE_B pointing to its relative line in MASTER_TABLE;
4. In the original file line, there is nothing I can use to join a MASTER line with a PARENT line.
The result would be:
MASTER_ID PARENT_DATA
1 PARENT_TABLE_A1
1 PARENT_TABLE_B1
2 PARENT_TABLE_A2
2 PARENT_TABLE_B2
I tried to use both: SEQUENCE and Sequence.NextVall (CurrVal) but they only work when using ROWS=1 and the file I need to load has millions of rows, so I need direct path loading.Also, I read about External Table, but it does not suit my needs because the Application server is not the same as Database server, which is needed by external tables.
in this case is better load the data to a temporary table and then insert to the other tables, I found almost the same question in the topic pointed by the link below: URL....

In my below code the procedures "total_score_proc" and "CopyInternalScores" are calling "score_proc" procedure 50 times
for different variable values.
Instead of calling the "score_proc" procedure 50 times.I want to hold the values in to collection , defining it in package and call that procedure only once.
how to implement "score_proc" using bulk collect.
CREATE OR REPLACE PACKAGE total_score_pkg
IS
PROCEDURE total_score_proc(pBUID IN STAGING_ORDER_DATA.BUID%TYPE,
OrderNum IN STAGING_ORDER_DATA.ORDER_NUM%TYPE,

I need to implement the foreign key on a column of a table from 2 tables. My requirement is in bellow.
drop table t1;
create table t1 (slno number, acc_no number);
drop table t2;
create table t2 (acc_no number primary key, acc_name varchar2(100));
drop table t3;
create table t3 (acc_no1 number primary key, acc_name1 varchar2(100));
[code]...
It is provided that the values of acc_no in t2 and acc_no1 in t3 are unique.Now it required that while inserting into t1 , the system will check either t2 or t3 tables.

I have two large tables(rptbody and rpthead) which has over millions or even more records. Below is the table schema
describe rpthead
Name Null Type
--------------------------- -------- -------------
RPTNO NOT NULL NUMBER
RPTDATE NOT NULL DATE
RPTD_BY NOT NULL VARCHAR2(25)
PRODUCT_ID NOT NULL NUMBER
[code]...
What I want is getting all data if the referenced RPTNO belongs to a particular product_id from rptbody table, here's the sql
SELECT t0.LINENO, t0.COMMENTS, t0.RPTNO, t0.UPD_DATE
FROM RPTBODY t0
WHERE
(
t0.RPTNO IN
(
SELECT t1.RPTNO FROM RPTHEAD t1 where t1.PRODUCT_ID IN ('4647')
)
)
ORDER BY t0.LINENO
Since the result set is pretty large, so my application(think it as c couple of jobs, each job should be finished in a time window) can only process a subset of all data, so I need pagination so that the next job can continue the processing until all data is processed, below is the SQL with pagination
select * from (
select a.*, ROWNUM rnum from
(
SELECT t0.LINENO, t0.COMMENTS, t0.RPTNO, t0.UPD_DATE
FROM RPTBODY t0
WHERE
(
[code]....
As you can see each query will take 100 rows from the db. The problem for now is that the query taking too much of time(10+ mins), I know the slowness is due to "ORDER BY t0.LINENO", but it's required for pagination.

i am looking to write a query that will count all NOT NULL queue values in a table that belongs to a certain group, but not sure how to write it. The following is what I have wrote, but just wanted to clarify how to implement count case based on 2 criterias.
select *
count(case when queue is not null then 1 end) over(partition by group) as queue_orders
from table_a;
For example if I have 10 jobs that belong to group 1, but I would like to count all group 1 jobs that have a queue value.
I have no data at the mo, just something that I am trying to start off.

how to write below query in pl/sql cursor. The help table has two associated tables, help_txt and help_id, which will have strings of data concatenated into one sales contact record. There are multiple lines of text per comment and multiple lines of resolution text at 40 characters per line. The key to the help_text table (id, date,seqno) is the main key to the help_txt table and help_id t table with a sequence added to each table
The formatted string will contain some text and variables with the comment lines (1-10 or more) concatenated first, followed by the resolution lines (1-10 or more). There will be multiple comment and multiple resolution lines. The Cust_Cmnt_Txt lines and the Resolved_Desc lines should be concatenated and formatted in the following string (% marks the variable string) :
'help taken ' %help.Taken_Dte 'received from the following source: ' %help.id. 'Remark Text: ' %help_text (where help_txt_Seq = 1) %help_text (where help_text_seq = 2-10 or more) 'Resolution: ' %help_id_Res_Txt.Resolved_Desc (where help_ID_Txt_Seq = 1) %help_ID_Res_Txt.Resolved_Desc (where help_id_Txt_Seq = 2-10 or more)
