Hi

There are 3 tables

ACE2_LIST_STATUS
ALS_LIST_ID VARCHAR2(30)
ALS_LIST_STATUS CHAR(1)
ALS_LIST_DATE DATE

Then one table ACE2_LIST_OUTPUT

(this table has no date field,so i specified the above table,because whatever list details gets inserted into the below table a similar the list id of it gets into the status table)

The requirement is such that

Currently this table contains data of 3-4 years

we need to keep 6 months data in this table and need to create one more table that will have last 18 months data.

others need to be deleted and this should be a regular process.

How can i proceed for implementing this functionality?

Thanks

Partition your tables and use partition exchange.

but there is no date field in the main ace2_list_output table,how to implement range partitioning?

Also this is a table used by a existing applicaton,doing partitions in this,will it have any consequences??

First, how can you have three tables with the same name?
Second, what is the common column?

Can you try to view your question as someone other than yourself and ask, "What information could I provide that would actually be helpful and before others have to ask me for it?"

may i know where i specified that 3 tables are having the same name?I need clarification on your question

secondly


the ace2_list_status which is having the date field
and the ace2_list_output table where history data gets inserted
from the aplication have alo_list_id in common.

hence we need to keep the 18 months data in one more history table
and ace2_list_output table should contain last 6 months data.

Of which data?

Post a description of each table.
Explain what is in each table.

In ACE2 list output we can determine the date of the row by matching it with ACE2_LIST_STATUS ALS_DATE field

In My Opinion, it would be simpler with only a single table & view on top of it.
I see no benefit for maintaining 2 separate tables.

I agree with Ana. In addition you could partition this table and have an easy way to history the data.

Can anyone tell me the methodology of how to partition this table
as the date filed being in ace2_lis_status field.

i am new to this partitioning concept.How to implement partition exchange here?
and seeing the requirement in what frequency this will be refreshed?

Will it have any effect on the existing application?

As Ana said, merge the 2 tables into a single one, then you have a date field in the table.
If you don't want to modify the application, create 2 views upon this tables that simulate the 2 previous tables.

so what i can understand is
create view1 from ace2_list_outout and ace2_list_status which will have the date field

and then create view2 of same structure as view1 without data,then apply partitions and exchange partitions

am i right?

Not at all.

Create a new table that merge columns of both current tables.
Drop the old tables.
Create views upon new table that simulate the old tables.

Hi Michel

This archieving needs to be done to redure the data from the main ACE2_LIST_OUTPUT table,now the existing application makes use of both ace2_list_outout and ace2_list_status extensively,

they cannot be dropped?

Please advice?


Any document to read on partition and partition exchange mechanism.


Seeing the requirement and is partitions the only way to go about it?

can you let me know how to schedule this process?

Thanks

If you use this, they don't see the difference.

I am not clear in this point.The bottom line is to reduce the data from ACE2_LIST_OUTPUT and run the job in monthly basis which will do this removing job andpbut the archieved data in the backup table

nad house keeping scripts to run for both history table and ace2_list_output table for maintaining 6 months data in ace2_list_output
and months data in the history table?

How can a view help?So are you saying if we drop the views then the base tables will get affected as well.


Keeping in mind the ace2_list_ststus and ace2_list_output cannot be dropped as they hold key in the application

Can't say more, if you don't understand give up this solution and try something else.

But lastly making my point once again

ACE2_lIST_OUTPUT AND ACE2_LIST_STATUS cannot be dropped

Drop the old tables.

Of course, if you start with step 2 this will not work.

Create a new table that merge columns of both current tables.
Drop the old tables.
Create views upon new table that simulate the old tables.


Ok i can create a view,but throuout the application there are critical transactions tasking place in ace2_list_output table.

In your second point

drop old tables--means ace2_list_output and ace2_list_status right?

You think it will be fine with the application?What if the create view fails for some unexpected reason?

Within this time when we are dropping old tables then what about the transactions taking place?

Even if we proceed for this?Do you mean now we now need to do all the application transactions on the new views simulating the old tables??
