what is the best practice to implement in Indexing,is it global indexing or local indexing, I would like implement one of them in object that has been partitioned horizontally.i dont know exactly what to make of it.
View 9 RepliesI have, for example, two tables: COMPANIES and EMPLOYEES. COMPANIES has a primary key on column COMP_ID. EMPLOYEES has a foreign key EMP_COMP_ID. I always do query COMPANIES with WHERE clause on COMP_ID and COMP_ADDRESS. What indexes on COMPANIES should I create in this case? First unique on COMP_ID, second composite on COMP_ID and COMP_ADDRESS? Or one unique index on COMP_ID and COMP_ADDRESS will be enough?

View 3 Replies View Related Does Oracle supports an index that only contains a sub-set of the records in a table?
For eg - A table has 1 million records, can we have a index which contains suppose 100k records. We have used a similar logic in DMSII in Unisys. Not so sure if Oracle supports it.
i want to ask about indexing in partition table. i have table that indexed by local index. when i want to select all data. I execute this query
select * from Book_Issue_Part where status='Pinjam';
but it does not select all data, only partly data have selected. is it a wrong query to select all data in indexing partition table? so what query should i execute to get all data.
however im taking database size into account. i believe there has to be some sort of medium when it comes to infrastructure and performance.
this is specific to tables which map other tables. these tables that im creating usually consist of only 4 columns. 3 columns are mapped ids and the other a date in field. the 3 columns need to be indexed because they are used in joins within views. also those fields in the other tables are indexed as well.
DB: Oracle 10g R2
OS: SUSE Linux SP 1 x864
We are maintaining a DR of our Database Server(oracle 10g R2 atop SUSE SP1 Linux) using Platespin(
[URL]......
Platespin is set to replicate(block based), incremental data(delta) every 1.5 hour from Production to DR site over a 30 Mbps dedicated fiber link.
Our maximum changes of data per day(during business hours) wont exceed 300 MB. During business hours Platespin replicates at least 1 GB at every replication cycle, while during off hours it replicates 300 to 500 MB per replication cycle. We are facing this strange issue with this box only(SLES 10 SP1 + Oracle 10g R2), we have protected MS Exchange 2007 Server based workloads without this strange issue, i.e in case of Exchange only delta replicates from Production server to DR site on Platespin.
Platespin support says us that Oracle re-indexes its database for better performance, so it is possible that re-indexing causes the blocks level changes on the storage, and since Platespin works on Block level, thats why it replicates so much(even though data is not changed that much)
here is actual words of Platespin support
<snip>
I think whenever Oracle database Indexing happens, it changes almost most of the Blocks of database and Platespin replicate all those Blocks.
As you know, Platespin checks the Date/Time attribute of every blocks before replication and if Date/Time attribute changes from last replication, it considers as changed block and replicate those blocks on Platespin Appliance. So, my suggestion is just look into the Oracle server behaviour before/after Data indexing process and do needful or do some workaround to overcome this issue.

is there anything we can do at oracle level ?
I have two databases called
a) Old Retailer database
b) New Retailer Database
We cant delete old database but we are using and we want to use both of them.
Now problem
Both dbs have a table called retailer.
I want to prevent duplication in them.
I.e it there is a retailer 12 created in old one new one shldnt allowo us to create retailer
id---12
similarly if there is a retailer 13 in new one it shouldnt be created in old table
retailer ids are unique. its not the case that with retailer id for example 5 there is a
different retailer in these two tables of diffferent DBS. Its unique
Now I have to put this criteria
how can i do it?
Second questions===================
if a primary key is auto increment. how can i skip some numbers lets say it is 1,2,3,4
i want that when next record shld be inserted it shld be 6 not 5. i dont want to feed the value 6. i want to know how to change indexing of primary key to skip some numbers when its set to auto increments.
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.

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....

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));

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.
