Refreshing a table from a database

I executed the tutorial "Sun Java Studio Creator 2 - Tutorials - Performing Inserts, Updates, and Deletes".
I am experiencing an anamoly in that when I select a new person for the selection where clause, the data for the previous person remains in the table. There is one case where the new data is correct and that is when there is no data selected, ie the table clears.
When the new person has more rows than the previous person the additional rows are appended to the previous persons rows When the next person has fewer rows than the previous person the previous persons data is truncated but the new persons data is not displayed.
The tutorial has a refresh() statement that doesn't seem to be clearing prior data.
I looked at the javadoc for 'cachedrowsetdataprovider' and it has a 'close()' method but no coressponding 'open()'.
How can I assure that prior results are deleted from the rowset?
thanks

Hi!
U can do this via DTW.
First extract the Datas from your other DB in a Excel with all need fields to import.
Import that into new DB via DTW.

hi
what are the apps version local and remote database???
Snapshot too old errors occur because Oracle can 't reconstruct a consistent
image of a block for the purposes of a consistent read.
I feel at remote database, you are using UNDO, it will be rather easy to iincrease the undo retention time or increase the undo tablespace size.. if you are dealing with roll back segments, you may have rollback segments whose optimal values are too small...
increase roll back segments size and select again then

Replicate some tables from local database server to Remote database sever

how can i replicate some tables from local database server(Oracle 8.1.7 on windows 2000 server) to a remote database server(Oracle 8.1.7 on Sun Solaris)
whenever there is some insertion or updation on the table of base(main) database it should get updated to the remote database server
or
on time base for example: every 2 hours
please help me!!!!

It all depends on waht you are going to do with the data on the remote.
if tehre are no updates there, creating a simple materialized view on the remote to pull it's data from the local should suffice.
If there are updates on the remote, you will more than likely want to look into either Multi-master replication, or updatable materialized views.

Select query based on joining of tables from different database is taking too long

Hi Team,
Select query on table with millions of records is taking very long time. It took 50mins, the below query is joining on multiple table from two databases DB1.dbo.Table1 contains 100 million records and also Table3 and Table4 (of different database) might
contain close to 1million records.
Select T1.*
From DB1.dbo.Table1 T1
Join DB1.dbo.Table2 T2 on RTRIM(T1.Col3) = RTRIM(T2.Col3)
Join Table4 CA on RTRIM(T1.Col1) + T2.Col2 = CA.Col1
Join Table3 U on CA.Col2 = U.Col2 AND RTRIM(T2.Col2) = U.Col3
Where U.Col4 NOT IN ('A1', 'A2', 'A3', 'A4', 'A5', 'A6','A7','A8','A9')
And (T1.flg IS NULL OR T1.flg = 'N')
And LTRIM(RTRIM(T2.Col2)) NOT IN ('B1','B2')
How can i improve the performance of this query. Actual thing is update the data in Db1.dbo.table1 based on the conditions but if the select is taking close to 1hr then update will take hours together. Indexes already implemented on all the tables.
Thanks,
Eshwar.

Join Table4 CA on RTRIM(T1.Col1) + T2.Col2 = CA.Col1
This join is not working with spaces if Rtrim is not used.

How to import a table from another database using DB toolset.

Hello All
I would like to import a table from one database to another using DB toolbox.
I do not want to import all data to LV and then save them to another database. Instead I would prefer to use SQL syntax.
Does anobody know how to write SQL command to import whole table from one database to another?
I have found in some SQL manual that INSERT INTO should work, but JET4 returns an error that table (e.g. c:\mydatabase\table1) can not be found.
Thanks in advance

HOW TO SOLVE THIS PROBLEM?

I cant see any join conditions in your query posted. Whats the purpose of the query above. It will just bring you a cartesian product (cross join) of tables involved subjected to filters. Are you sure this is the correct query?
The error you're getting may be because you've not yet populated DimProduct or may be because of logic you used in popultaing DimProduct causing it to miss some records which is what query is referring to in above case.

What is te best way to copy a table from a database to another?

Hello friends:
I have two databases: an Access database and an Oracle database. I must copy the data from al tables from the Access database to the oracle database. The tables in the both databases are equal (number of columns, type, etc).
I read an resultset from acces (select * from table1) and I insert every row in the Oracle database with an while loop (while (r.next)...). It works fine when there are a few rows, but I have a table with over 200000 rows, and when I'm copying the row number 30.000, the system goes very slow...
How can I copy tables from a database to another more quickly?
Thanks!

CASE #1
The most efficient method would be to copy all the rows from Microsoft Access and write them to a text file using Access's native interface (not JDBC), then use Oracle's SQL Loader utility (not JDBC) to insert the data.
You can insert 200,000 rows of 80 bytes each in 30 seconds or less even on a modest Oracle system using SQL Loader. The extract from Access is very dependent on the size of the CPU and the available memory.
Hint 1: Avoid explicit or implict network traffic.
Hint 2: Extract and load from local drives rather than networked or shared drives on other services
Please note that this is done for efficiency of load, but has issues related to error checking, and operational scripting.
Anything else you do or use will be slower than the method (above).
CASE #2
If you want to integrate this into a single JDBC program which will provide better operational management of the process, then you can simply connect to both databases in your Java program, then read the rows one at a time from Access, insert them using the Batch mechanism of JDBC to Oracle. You will also want to set the FetchSize in Oracle to a larger value then the default (i.e set it to 100 vs 10).
Hint #3 You may want to look into alternative JDBC drivers for accessing MS Access, rather than the JDBC-ODBC bridge which is not optimized for MS Access. You may also want to consider using the OCI8 driver from Oracle rather than the thin driver. Both provide Type 4 functionality but I have heard (not experienced) that the OCI8 driver is better for managing batch style of processing like yours
Good luck!

Problem adding more than 1 table from a database

I am running Crystal Reports 2008 on windows server 2008 and connecting to an ODBC database using IBM Client access driver. When I create a new report and only add one table from the database, everything works fine. If I try to go add a second table to the report, then I get an error - Crystal Reports has stopped working - there is no other useful information. I have also tried creating a new report and adding 2 tables at the same time, it also blows up before I even get to the linking screen.
I have also tried opening a report that was created in Crystal 11 that has 2 or more tables in it. The report will open and run successfully in Crystal 2008.

Hi Gwyn,
Moved this post to the Database Connectivity Forum.
Have you installed any CR patches? If not please do so. Also you can find our DataDirect ODBC drivers from this link also:
http://service.sap.com/sap/bc/bsp/spn/bobj_download/main.htm
Select Crystal Report, 2008 and you'll find Service Pack 2 and the Data Direct ODBC drivers. Try both and then reply if you have still have a problem or if it now works.
Thank you

How to copy a set of tables from a database to another periodically?

We have a 4 node RAC primary database(10.2.0.2) with a physical standby(10.2.0.2) on our production site. Offlate we noticed that one of the applications(APP2) is causing heavy loads due large data downloads on the primary database servers. Our primary database has 2 schemas,
1) one being the main schema with all objects, (USER1)
2) and the other has views that query some set of tables from the main schema. (USER2)
The application APP2 uses USER2 views to query and download huge data periodically. We need to be able to give accurate data results to APP2, but in the same time take off the load from the database, as APP2 is not our main application.
We would like to know if there are any cost effective options in oracle to do this, and if so, what is the best option? Anyone has any experience setting up something like this before?
We have thought of creating another 10.2.0.2 database on a different server and giving it regular updates(like data feeds) from the current database. The current database data changes quiet often, so the data feeds would have to be done often to keep the data current on the new database. So, we are not exactly sure how to go about it. Would a COPY command help?
Please advice.

user623066 wrote:
Our 4 node RAC is already busy with our main application, which has its connections spread across all 4 nodes.
Our main applications services are the same on all nodes and use all 4 nodes in the same way.
There are some other utilities that we run from one of the app servers that connect to only 1 of the nodes.
APP2 uses all 4 servers, which is again controlled by connection pooling and distributes the load.Wouldn't separate services be more beneficial here? If APP2 is locked down to one node during normal operation, that ensures that other connections aren't going to be competing for hardware with APP2 on 3 of the 4 nodes. If APP2 is generating less than 25% of the total load, you can let the other applications use whatever hardware resources are left idle on the node APP2 is locked down to.
By Large data downloads, I meant both increase in network traffic and the CPU load on the database nodes.
We are already using resouce manager to limit the resources allocated to USER2 that APP2 uses.
And we have also limited the large downloads to take place in the early hours of the day when the traffic from our main application is less.
But this has still not been optimal for the usage requirements for APP2. APP2 is also doing queries all through the day, but has a limit for the number of rows downloaded during peak hours.Can you explain a bit more about why using Resource Manager hasn't been sufficient? That's normally a pretty good way to prevent one hungry user from drastically affecting everyone else. Perhaps you just need to tweak the configuration here.
Logical Standby seems a good option. But we need to keep our physical standby in place. Is it possible to have a logical standby and a physical standby? (ofcourse on separate servers)Sure. You can have as many standby servers of whatever type you'd like.
Could we use a COPY command to copy data for the set of tables to a new database? Or is that also a complex option?You could, yes. COPY is a SQL*Plus command that has been depricated for copying data between Oracle databases for quite a while. It only works from SQL*Plus and would only be designed for one-time operations (i.e. there is no incremental COPY command). I can just about guarantee that's not what you want here.
How do materialized views work? Wouldn't they still reside on the main database? Or is it possible to have remote materialized views?You probably don't want materialized views, but if you decide to go down that path
- You'd create materialized view logs on the base tables to track changes
- You'd create materialized views on the destination database that select data over a database link back to the source database
- You'd put those materialized views into one or more refresh groups that are scheduled to refresh periodically
- During a refresh, assuming incremental refreshes, the materialized view logs would be read and applied to the materialized views on the destination system to update the materialized views.

How to update date in a table from another database

Hello,
I am trying to code a way to Update my Testing database from another database. In the coding below the database that has the updated data ends in Restore.
Use ClientDB_MASTER_Restore
Truncate Table ClientDB_MASTER_Testing.dbo.Activity_Tracking_AZ
GO
SELECT * INTO ClientDB_Master_Testing.dbo.Activity_Tracking_AZ
FROM Activity_Tracking_AZ
Go
I know with this Technique the table must be truncated if not deleted first. There is probably a better way to do this which I'm very open to. I'm also looking for coding that will roll back any changes made should an error occur.
As always, any help is greatly appreciated.
David92595

USE ClientDB_MASTER_Testing
go
SET XACT_ABORT ON
BEGIN TRANSACTION
Truncate Table dbo.Activity_Tracking_AZ
-- SET IDENTITY_INSERT dbo.Activity_Tracking_AZ ON
INSERT dbo.Activity_Tracking_AZ (col1, col2, ...)
SELECT col1, col2,
FROM ClientDB_MASTER_Restore.dbo.Activity_Tracking_AZ
-- SET IDENTITY_INSERT dbo.Activity_Tracking_AZ OFF
COMMIT TRANSACTION
If you find it boring to type the column lists, just find the table in Object Explorer, and drag the columns node to where you want the column list.
You need the SET IDENTITY_INSERT command if the table has an IDENTITY column.
By wrapping the code in a transaction, you are not left with an empty table if the INSERT fails. The command SET XACT_ABORT ON makes sure that the batch is aborted and rolled back in case of an error.

How to Copy (or) Transfer data in a BLOB Table From one database to another

Dear Members,
I want to Copy or Tranfer the data in a Table having BLOB Column from one database to another database.
The Problem is that I am using COPY Command.
COPY from scott/[email protected] to k5esk_ldb2/k5esk_ldb2@k5_ist.world CREATE BLOB_TABLE using select * from BLOB_TABLE;
This is working only if the table is not having BLOB Column or CLOB columns.
Is there any other way to do the same.
Appreciate any Help.
Regards
Madhu K

You could try using export/import utilities, but may run into tablespace issues if the tablespaces are not the same between the two databases. You can also try Data Pump using the REMAP_TABLESPACE variable if you tablespaces are different. You could also write your own export and import code...there are plenty of examples of that to copy.
