Using ADF against changing table structures

Hello,
We are developing a JSP app that will hit the same tables in different dbs/scheams, but the attributes (columns) of the tables could change (all except the primary key and name of the table). I want to write the app once and allow it to hit the same tables even if they have different columns (depending on what db is connected). As an example, using ResultSetMetaData I can easily "loop" thru through all column "labels" and then loop thru the ResultSet to display the data.
I am assume that ADF would NOT be a good fit for this type of application but I wanted to see what others had to say.
Thanks.

The biggest problem is that the number of columns in the tables could differ. Is it possible/feasible to create dynamic ViewObjects based on the structure of the currently connect db? As in, once the app initially connects, it dynamically build the ViewObjects and then allows the app to access these ViewObjects as needed.

Problem changing table structure CDS

I created a table using a .hdbdd file. I was then able to import data from a csv file. Everything worked like a charm. Later I tried to add a field to the table but when I tried to save the updated hdbdd and csv files I get an error that the number of columns in the table and csv file don't match. So, I tried to delete the entry for the table from the hdbti table. It allowed me to save the file but still get the column mismatch error.
Then I deleted the database table but now I get an error: Table import target table cannot be found. Table import target table cannot be found.
Finally, I tried to delete the csv file but the file appears in the list of files but I can't open it and I still get the same error.
Now I can't change any part of the data model with getting the error. Is there no way out of this maze?

Use of value change table cdpos

i got the idea from madhvi (thanx) about using two tables when fetching data from cdpos table .like we can give tabname = 'eket'
or = 'ekpo'.but what about fieldname which are associated with these two tables how to write feilds,like for the first two which belongs to eket table i write fname in ('eindt', 'menge') but what about the third field netpr related to second table ekpo.actually in output the changes of only first two is reflecting if am using 'or' for distingushing between tables and fields.

TIPS(18) : CREATING SCRIPTS TO RECREATE A TABLE STRUCTURE

제품 : SQL*PLUS
작성날짜 : 1996-11-12
TIPS(18) : Creating Scripts to Recreate a Table Structure
=========================================================
The script creates scripts that can be used to recreate a table structure.
For example, this script can be used when a table has become fragmented or to
get a defintion that can be run on another database.
CREATES SCRIPT TO RECREATE A TABLE-STRUCTURE
INCL. STORAGE, CONSTRAINTS, TRIGGERS ETC.
This script creates scripts to recreate a table structure.
Use the script to reorganise a table that has become fragmented,
to get a definition that can be run on another database/schema or
as a basis for altering the table structure (eg. drop a column!).
IMPORTANT: Running the script is safe as it only creates two new scripts and
does not do anything to your database! To get anything done you have to run the
scripts created.
The created scripts does the following:
1. save the content of the table
2. drop any foreign key constraints referencing the table
3. drop the table
4. creates the table with an Initial storage parameter that
will accomodate the entire content of the table. The Next
parameter is 25% of the initial.
The storage parameters are picked from the following list:
64K, 128K, 256K, 512K, multiples of 1M.
5. create table and column comments
6. fill the table with the original content
7. create all the indexes incl storage parameters as above.
8. add primary, unique key and check constraints.
9. add foreign key constraints for the table and for referencing
tables.
10.Create the table's triggers.
11.Compile any depending objects (cascading).
12.Grant table and column privileges.
13.Create synonyms.
This script must be run as the owner of the table.
If your table contains a LONG-column, use the COPY
command in SQL*Plus to store/restore the data.
USAGE
from SQL*Plus:
start reorgtb
This will create the scripts REORGS1.SQL and REORGS2.SQL
REORGS1.SQL contains code to save the current content of the table.
REORGS2.SQL contains code to rebuild the table structure.

Change Data Capture,Change Tables

Hi,
We installed Change Data Capture in our DB (10gR2),however there is a problem with change tables.Change tables are being cleaned somehow.According to text quoted below,the job which is cleaning change tables is cdc$_default_purge_job.However
select log_date
+, job_name+
+, status+
from dba_scheduler_job_log
where job_name='CDC$_DEFAULT_PURGE_JOB';
results no data. Also this morning i came across that data cleansing again, and run the query below.And again no result.
select job_name
+, session_id+
+, running_instance+
+, elapsed_time+
+, cpu_used+
from dba_scheduler_running_jobs;
/*We didn't even use DBMS_SCHEDULER.SET_ATTRIBUTE procedure so far*/
What is cleaning change tables and how can i control it?
Tnx in advance
Quotation:
Change Data Capture creates a purge job using the
DBMS_SCHEDULER package (which runs under the account of the publisher who created the first change table). This purge job calls the
DBMS_CDC_PUBLISH.PURGE procedure to remove data that subscribers are no longer using from the change tables. This job has the name
cdc$_default_purge_job. By default, this job runs every 24 hours. You can change the schedule of this job using
DBMS_SCHEDULER.SET_ATTRIBUTE and set the
repeat_interval attribute. You can verify or modify any other attributes with the
DBMS_SCHEDULER package.

Setting up CDC is a fairly complex process with different options. Setting just the filter in OWB is only a very small part.
There is a blog post below on how to use code templates to do CDC which gives some insight;

ADF Faces Core Table, TableSelectOne question

Greetings
I am using ADF Faces Core Table to display a list and I have it setup with TableSelectOne, it works great. My question is this, I set required = true on the select button and it works. If I dont select one it no longer submits. My question is how do i get the error message back out I tried adding an af:message tag with from = tableSelectOne1 and I dont get anything back out. Is there a way to get this error message out so I can display it for the end user?
Thanks
tro

Hi,
Try using af:messages instead, as it displays all messages added to the FacesContext.

Importing table structure only consumes space in GB

Hello,
I have used oracle 9i Exp commmand to export a schema structure.(No rows) There are only 150 tables and the export is perfect without any warnings.
When i try to import into a different schema , I can see that it consumes 3 GB of space in the default tablespace for that schema. I checked the free space in the tablespace before importing...there is 3 GB of free space..
When i start import it gets full , and import hangs. It does not proceed any further. Im not able to understand, why 3 GB of space it is using for just the table structure.
Please help
Thanks

Im not able to understand, why 3 GB of space it is using for just the table structure.neither are we without your export and import commands. I could take a guess though. That would be that your export uses compress=y either explicitly or because it's the default, and also that you are using dictionary managed tablespaces on your target. In that case each new table gets created with an initial extent the same size as the data on the source. In this case the immediate solution is not to use compress and the longer term one is to move as well to locally managed tablespaces.
still if we could see the commands you used then we wouldn't need to guess.

Is this with the Travel database or another database?
If it's another database then make sure your columns
allow nulls. To check this in the Server Navigator, expand
your DataSource down to the column.
Select the column and view the Is Nullable property
in the Property Sheet
If still no luck, check out a tutorial, like Performing Inserts, ...

How to refresh a table of data after inserting a row using ADF BC

Hi,
i am using ADF BC, JSF to construct a page to browse and another to create/update record. But after creating or updating the record it is not reflected when i come back to browse page.
I tried to insert invokeaction in page definition page but i can not find the iterator bindings for that table in Binds option.
can any one provide any example how to do it.
Please help me.

On the page def for your submit page, add inside the executables (on the structure pane) your iterator you want refreshed (if it isn't already there).
Then double click on the submit button and bind it to a backing bean. My method in the backing bean looks like:
    if ( !operationBinding.getErrors().isEmpty() )
        return null;
    DCBindingContainer dcbindings = (DCBindingContainer)bindings;
    DCIteratorBinding appsIter = dcbindings.findIteratorBinding("ApplicationsIterator");
    appsIter.executeQuery();
    return null;
}The executeQuery method will refresh that iterator for your return page. The "ApplicationsIterator" is what the structure pane calls your iterator. Works for me.

Authenticate ADF application using adf security wizard against LDAP OID

I have an adf application which i intend to authorise using LDAP. For now , i have actually hand coded in java for authenticating the users of my application. Using JNDI I directly connect to LDAP and authenticate users. However , recently it came to my notice that i can also do that using ADF sercurity wizard , but i am unable to do so. which securing the ADF application ,no where in the wizard LDAP configuration is mentioned. do i have to change some file manually ? i have no idea on how to proceed on that.

i have setup wls , making th OIDAuthentication as Sufficient. but i dont know how to configure from ADF side so that it can authenticate against LDAP. when i try the ADF sercurity wizard option , it tells me to create new Roles . Is there any way where i can import the ldap credentials to the security wizard ..?

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.

Milind...

go to tables statements -
> double click on the structure----> it will takes you to that structure

Change of structure of database table

A custom database table has been created and is already in use by 10 programs. Now a new requirement has come to add a field i.e. a check box to the database table to be used by one of the 10 programs. Can we change the structure of the database table after activating it and when the table is in use? Please provide me inputs on this.
Thanks and regards
Radhika

Yes. U can change it. But I suggest u to do it through the process of 'Append Structure'.
If u have any probelm after changing follow this process.

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

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
