Suggestion required in target table structure change

Hi all good morning,
I have one requirement. I have a target table T with some coulmns. Now I need to add one additional column to T and one procedure is there to populate the data for new column. This target table T is used by 50 mappings.my questions is if we change the structure of the table do we need to import(I think we must import). If we import what could be the impact of this re-import. do we need to rebound and validate alla the mappings and then deploy?
the other possibility what I can do is I will create a replica of T as T1 with one additional column. I will create a new mapping which dumps data from T to T1and I will replace my T with T1 in my reporting environment.
pls suggest which is good one. it is urgent.
thanks in advance.
Viki

Hello, if you don't need the new column in the 50 mappings, you can temporarily leave them alone (you say it's urgent), and just feed the new col..
When you have more time, you should reconcile the mappings with table T and re-deploy them. OMBPlus scripting is ideal for this task.
Hope this helps, Antonio

I'm not sure to understand what kind of module you're talking about.
Anyway, there are several docs available in MOS which shows the features differences over the versions, have a look :
PeopleTools Cumulative Feature Overview Tool ID 793143.1*
But I didn't find any starting by your (very old) Peopletools version.

Ho to track table structure changes ?

Hi
I need to know how to track the table structure changes ?
I mean how to know when , which column was added/dropped/altered by which user for a table.
Is there any DD view for the same in Oracle??

Demantra PTP table structure changed in 7.3.X.X

The staging tables structure is changed in Demantra version 7.3 onwards as compared to Demantra 7.2.X.X. Some of the "Required" columns in "BIIO_Promotion" table which is used to load promotion data`has been removed in Demantra 7.3. And some more "Required" columns are added in "BIIO_Promotion" table.
The disappointing thing is that the implementation and user guide doesn't speak about it. How the implementer know, what type of values to load in these mandatory columns to populate the promotion data in Demantra.

Table structure changed in testing system after system refresh.

Hi Team,
Recently we underwent a system refresh in Testing System where the Testing data is filled with Production data. But now we find that in one table some fields which we had deleted they are again found there. The version history of table is also gone. The table object was under testing in testing system and after which it was supposed to be transported to production. I believe System refresh only means refresh of data and it has nothing to do with table structure. Please correct me if I am wrong. Please also let me know what could be the reason of those changes in table if it is not System Refresh.
Regards,
Amit

I believe System refresh only means refresh of data and it has nothing to do with table structure.
Alas, you were wrong, after all table definition are data too, as program sources...
You have to re-import every transport request which was not yet transported to production in your test system.

Oracle Data Pump - Table Structure change

Hi,
we have daily partitioned table, and for backup we are using data pump (expdp). we policy to drop partition after backup (archiving).
we have archived dump files for 1year, few days back developer made changes with table structure they added one new column to table.
Now we are unable to restore old partitions is there a way to restore partition if new column added / dropped from currect table.
Thanks
Sachin

If a new column has been added to the table, you can import only the the data from the old structure to the new structure. Use the parameter CONTENT=DATA_ONLY.

Table structure changes

Assuming that an OraLite 10g is now running on CE.Net and Msync is working fine to do data synchronization between Oralite 10g and an enterprise 9i database. If I make structure changes to a table on the enterprise database, how do I reflect the changes to the OraLite database on the CE.net device.
Thank you.

There's a good post about this on metalink...
A) Add column
1. Upload all client data. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Change the Oracle8i/9i database schema (add column)
4. Create a Java program to call the Consolidator Admin API AlterPublicationItem()
5. Start Mobile Server
6. Execute a sync from the client
7. The new column should be seen on the client. Use MSQL to check snapshot definitions.
B) Drop column
1. Upload all client data. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Delete column of the base table in the Oracle database schema
4. Create a Java program to call the Consolidator Admin API DropPublicationItem()
5. Create a Java program to call the Consolidator Admin API CreatePublicationItem() and AddPublicationItem().
6. Start Mobile Server
7. Execute a sync from the client
8. The new column should be seen on the cliet. Use MSQL to check snapshot definitions.
C) Change column datatype
Changing datatypes in a repliatated system is not an easy task. You have to follow certain procedures in order to make it to work. Use DropPublicationItem, CreatePublicationItem and AddPublicationItem methods from the Consolidator Admin API. You must stop/start Mobile Server listener to refresh the cache.
1. Client syncs. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Drop/create column (do not use conversion procudures) at the base table
4. Call DropPublicationItem(). Check if the ErrorQueue and InQueue no longer exist.
5. Call CreatePublicationItem() and AddPublicationItem(). Check if the ErrorQueue and InQueue reflect the new column datatype
6. Start Mobile Server. This automatically resumes application
7. Client executes sync. This should drop the old snapshot and recreate the new snapshot. Use MSQL to check
snapshot definitions.
D) Drop table
1. Client syncs. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Drop base table
4. Call DropPublicationItem(). Check if the ErrorQueue and InQueue no longer exist.
5. Start Mobile Server. This automatically resumes application
6. Client executes sync. This should drop the old snapshot. Use MSQL to check snapshot definitions.
E) Add table
1. Client syncs. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Add new base table
4. Call CreatePublicationItem() and AddPublicationItem() method
5. Start Mobile Server. This automatically resumes application
6. Client executes sync. This should add the new snapshot. Use MSQL to check snapshot definitions.
F) Changing Primary Keys
Chaning PK is a severe operation which must be executed manually. A snapshot must be deleted and recreated to propagate the changes to the clients. This causes a full refresh on this snapshot.
1. Client syncs. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Drop the snapshot using DropPublicationItem() method o
4. Alter the base table
5. Call CreatePublicationItem()and AddPublicationItem() methods for the altered table
6. Start Mobile Server. This automatically resumes application
7. Client executes sync. The old snapshot will be replaced by the new snapstot using a full refresh. Use MSQL to check snapshot definitions.
G) To Change a Table Weight =>
Follow the procedure below to change the Table Weight parameter. The table weight is used by the Mobile Server/Synchronization to determin the sequence in which client records are applied to the Oracle database.
1. Run MGP to apply any changes in the InQueue to the Oracle databse
2. Change table weight using SetTemplateItemMetadata() method
3. Add/change constraint on the the base table which reflects the change in table weight
4. Synchronize

Table-Structure Change

Hi Guys!!!
I have created a Z***** table n activated,now i want to change the data type from FLTP to CHAR but the thing is am getting an error "Structure change at field level (convert table Z******).what i supposed to do?
Warm Regards,
Mohandoss P.

Hi,
Along with that message i think u will get 'ok' and 'delete' button will come..
please click on delete button.
but make sure that the table field is not using any where after deleting the table. other wise dependent programs will give dump.

Target Table Column Changes .....?

Dear All,
If the target table column gets changed, how can we implement in OWB Mappings? For instance today I have a column name as CTYNAM in the CITY_DIM, a couple of days after in the database it is renamed as CTY_NAME. How can I do the changes in OWB. Assume that this column is mapped to n number of transformations when extracted from source tables.
Thanks in Advance
Regards
Kishan

Good morning Kishan,
As an addition, if the datatype of columns has changed, the reconcile inbound might correct it for the reconciled table operator, but not for any other operator in your mappings.
Check all operators that use columns of which the datatype has changed, unfortunately that's a manual job (unless you're handy with OMBPlus, then you could use scripting to alter properties for all occurrences).
Good luck, Patrick

Last time the table structure changed

What is the best way to find out as to when a table structure was last changed? (Like adding or modifying a column) ?
I queried LAST_DDL_TIME in the dba_objects view but the problem is that it stores the last time the table was truncated (using TRUNCATE TABLE table_name), as we do truncates often. I was interested in find out when the table was altered. Any ideas ?

Hi,
i think database trigger will do better according to your need....
its simple and best.
Just create a new table and database trigger.
Like
create table db_ddl_log
username varchar2(30),
ddl_date date,
ddl_type varchar2(30),
object_type varchar2(18),
owner varchar2(30),
object_name varchar2(128)
create or replace trigger db_DDL_Trigger
AFTER DDL ON DATABASE
BEGIN
insert into db_ddl_log
username,
ddl_date,
ddl_type,
object_type,
owner,
object_name
VALUES
ora_login_user,
sysdate,
ora_sysevent,
ora_dict_obj_type,
ora_dict_obj_owner,
ora_dict_obj_name
END;
now check it.
SQL> select * from db_ddl_log;
no rows selected
SQL> desc a
Name Null? Type
NO NUMBER
SQL> alter table a add (name varchar2(1));
Table altered.
1* select * from db_ddl_log
USERNAME DDL_DATE DDL_TYPE OBJECT_TYPE OWNER OBJECT_NAME
SYS 06-MAR-06 ALTER TABLE SYS A
SQL> truncate table a;
Table truncated.
sql> select * from db_ddl_log
USERNAME DDL_DATE DDL_TYPE OBJECT_TYPE OWNER OBJECT_NAME
SYS 06-MAR-06 ALTER TABLE SYS A
SYS 06-MAR-06 TRUNCATE TABLE SYS A
Thanks

Table structure changes when using 'create table X as ( select * from X@remote_server )'

I need to create and copy data from a remote Oracle server to a local server. The command I use is
create table X as ( select * from X@remote_server )
with remote_server is the tns name of the remote Oracle server.
The local table is created and populated with data as expected but when I check the structure using 'desc X' it shows me all the CHAR fields of the local table are triple as large as of the remote table.
I guess the problem is the difference between the NLS_CHARACTERSET settings . The local charset is AL32UTF8 and the remote is WE8MSWIN1252.
How do I change the command to make the two tables have the same field sizes ?
Thanks,
Vu

Do you want to be able to store all the data from the remote table in the local table? Assuming you do, increasing the size of the column would be the correct behavior.
By default, a VARCHAR2(10) allocates up to 10 bytes of storage. In the Windows-1252 character set on the source, 1 character requires 1 byte of storage. So a VARCHAR2(10) has space for up to 10 characters. In the UTF-8 character set on the destination, however, 1 character can require up to 3 bytes of storage. So a VARCHAR2(10) may allow you to store as few as 3 characters. Since Oracle has no way of knowing what data you have (and will have) in the source system, it triples the size to ensure that all the data from the remote system will fit in the new table. If you want the columns to be the same size on the destination that they are on the source, it is highly probable that you'll get errors inserting the data because at least one value will be too large for the destination column.

Oracle 9i Lite: Table structure changed

Hello,
how do I add a new column to a database table? I mean what actions to I have to take to add the column to the database on the server and how is this change transferred to the clients? Are these changes impossible to do with Oracle Lite?
Stefan

Yes, this is possible. There are two ways you can update the clients...
1) repackage the app with the packaging wizard
2) use the consolidator API - see the javadoc.

Lookup Table and Target Table are the same

Hi All,
I have a requirement in which I have to lookup the target table and based on the records in it, I need to load a new record into the target table.
Being very specific,
Suppose I have a key column which when changes I want to generate a new id and then insert this new value.
The target table record structure looks like this
list_id list_key list_name
1 'A' 'NAME1'
1 'A' 'NAME2'
1 'A' 'NAME3'
2 'B' 'NAME4'
2 'B' 'NAME5'
As shown the target table list_id changes only when the list key changes. I need to generate the list_id value from within OWB mapping.
Can anyone throw some light as to how this can be done in OWB???
regards
-AP

Hello, AP
You underestimate the power of single mapping :) If you could tolerate using additional stage table (with is definitly recomended in case your table from example will account a lot of rows).
You underestimate the power of single mapping :) It you could tolerate using additional stage table (witch is definitely recommended in case your table from example will account a lot of rows), you could accomplish all you need within one mapping and without using PLSQL function. This is true as far as you could have several targets within one mapping.
Source ----------------------------------------------------- >| Join2 | ---- > Target 2
|------------------------ >|Join 1| --> Lookup table -->|
Target Dedup >|
Here Target your target table. Join 1 operator covers operations needed to get existing key mapping (from dedup) and find new mappings. Results are stored within Lookup Table target (operation type TRUNCATE/INSERT).
Join 2 is used to perform final lookup and load it into the Target 2 the same as Target
The approach with lookup table is fast and reliable and could run on Set base mode. Also you could revisit lookup table to find what key mapping are loaded during last load operation.

How do I create a target table with the same PK as the source table?

I am trying to create a target table in a mapping that will end up with the same primary key as the source table.
It is a simple map that simply uses a subset of the columns of the source table in the target table. I was wanting to create and bind a new table by dragging the columns I want from the source to the initially blank target table operator, change the column names and create a primary key to match the source table.
I can't seem to be able to create a constraint on the table in the mapping. I can create the constraint after the table is created and boound to the database object but the PK doesn't carry back into the mapping.
I need it in the mapping so I can use the UPDATE/INSERT operation and use the 'All Constraints' implementation. The mapping won't let me validate the object without the PK on it in the map.
Believe it or not folks, I am getting better at this.
Thanks very much for the guidance.
Gary

Hi Gary
You are close, you are really close... :-))
You need to do exactly as you propose plus one extra step. Build the map as you describe, binding the new table to the target. Then you edit the table definition to add the primary key and any other constraints you need. After this is the step that you are missing.
You need to do the following:
1. Go back and re-edit the map
2. Right click on the table
3. From the pop up menu, select Reconcile Inbound
4. Set any operators that you need for the UPDATE/INSERT
5. Save the map
6. Commit your changes
The first three steps above make the map read in the indexes and constraints that you set on the table. Finally, you need to deploy the table and then deploy the map.
Hope this helps
Regards
Michael
