Multibyte issue in Oracle Database Link

Hi Gurus,
Greetings!!!
I need to transfer data from Microsoft SQL Server 2005 to Oracle DAtabase 10g. I achieved it using Heterogeneous Connectivity. I can now issue queries but unfortunately i got an issue in displaying multibyte characters. I thought of using another Tool that can display multibyte data but it did not help. I even tried setting the initialization parameter HS_LANGUAGE to different characterset but still not able to display. Kindly help and advise how to resolve the said issue.
Many Thanks in Advance,
Benjie

Hi Kamkan,
My oracle database is configured to support multi language character.

How to execute remote query by Oracle Database Link

I use Oracle Database Link to query data from SQL Server. The query is like:
select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*
tableA and tableB is large and the result is relatively small. This query executes quickly in SQL Server since indexes are built both on the two tables. But it is very slow on Oracle Database Link to SQL Server.
I guess the join operation is performed on Oracle side not on SQL Server side, thus the indexes are not used. Since I just need the joined result, I prefer to perform the query entirely on SQL Server and get the small result only. But I have no privilege to create views on SQL Sevrer.
I konw that using SQL Server's linked server and OPENQUERY function can achieve this goal. I wonder how to do this on Oracle Database Link. Thanks!

DO NOT DO THIS....specifically:
"select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*"
You would be better off to do the following:
create a Materialized View in Oracle and once/day (or as frequently as you feel necessary) pull the data from SQLServer and then do the join locally by creating MV as TABLEA_MV and TABLEB_MV and then have views that have the REALTABLEA and REALTABLEB names that point to these MVs. This can be done without recompiling or changing your code. Trust me, I have seen this sort of thing in the past that completely crippled an IBM mainframe using DB2 along with a major network segment by having this sort of join via DB links. You must understand the ramifications of your "design" and I can tell you for certain that it is a very BAD!!! idea... Fix this before you are issuing another command: "alter DBA update resume/CV;"
The app went into production at 7AM. By 9:30AM, the mainframe had executed more than 10Billion I/O's. It took > 15hrs for the mainframe to recover once we shutdown the app and implemented the view/MV described above.
I will leave it as an excercise for the OP to develop the syntax for this.

Weblogic 5.1, Distributed Transaction and Oracle Database Link

We are planning to add a new functionality to run in Weblogic server and it
needs to update tables in two different Oracle databases. Since we are using
Weblogic 5.1 and it is unrealistic to upgrade to 6.1 in short term, we have
to deal with the fact that distributed transaction is not supported by JTS
on 5.1.
One workaround we can think of is to utilize Oracle database link. Instead
of having two connection pools, the application talks to only one database
and access the tables on the other ones through Oracle database link.
Therefore, when a session bean tries to update two tables on database 1 in
one transaction, one of the tables is just a link to the other database. We
hope that even though distributed transaction is not supported by JTS in
Weblogic 5.1, but since it is supported by Orable, it would work.
Do you think the above workaround would work? Does anyone have experience on
something like that?
Thanks in advance,
David Chen

Hi. You should be able to use any JDBC driver with WebLogic 5.1.
It may be the JVM that complains, if you use too old a JVM...

Hi All,
I'm trying to make a connection to mySQL database from oracle.
Oracle database runs on windows 2003 64 bit machine and version is 10.2.0.4.0.
my init<dbname>, listner and tnsnames looks like this and I can create database links without any problem at all. Also oracle to oracle database links are working fine on that machine as well.

Oracle Database link for AS400

Hi
i have two (2) database servers
1) Oracle 9i server
2) AS400 server
I want to create Oracle DataBase Link for AS400.
means i just want to connect AS400 system from oracle prompt by using
oracle database link.
please anybody help me in detail
Nasir,

There is two method.
One of that
(1) Buy Oracle Transparent Gateway for AS400/DB2 and install it to AS400.
(2) Set tnsnames.ora for connecting to AS400/DB2.
(3) Create database link
http://download-west.oracle.com/docs/html/A97615_01/toc.htm
Another of that
(1) Get odbc driver for AS400/DB2 (on your OS executing Oracle)
(2) Set listener.ora, inithsodbc.ora and tnsnames.ora.
(3) Create database link

But soddenly I receive this error :
Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "WMS". [SQLSTATE 42000] (Error 7303). The step failed
In this scenario the SQL SERVER AGENT Account is the Domain administrator.
When I restart the Server it begin to work fine again but from time to time I receive again the error mentioned above.

Bianca,
If you log directly into MySQL and issue the same query (select "subject" from "main_pages";) what data is returned?
I looks to me that you count is the number of rows in the entire table "main_pages"
while you select is for the data in the "subject" column only.
This seems to indicate that you have just one row in that subject column.
Regards,
Matt
WHAATT?
What do you mean by "just one row in that subject column"?
That makes no sense at all. A row is a row. A column is a part of a row. All rows have all columns, though not all columns of all rows will necessarily have an assigned value. Lacking a WHERE clause to filter rows, any SELECT should return all rows.

Variable database name in SQL Server query using Oracle database link

Hi All,
I have an ApEx 4.1 app running on 11g x64 (11.2.0.1) on Windows Server 2008 x64, and I have some data integration points with a SQL Server (2005 and 2008) that I need to establish. I have configured the database link with dg4odbc and it works beautifully... I can execute queries against the SQL Server database without any problems using the database link.
However, there is a scenario where the SQL Server database name is dynamic, and I need to generate it on the fly in a PL/SQL block, and then use that in a dynamic SQL query (all of this in ApEx). This is where I run into problems... when I am querying the default database based on the ODBC connection and I don't have to specify the database name, there is no issue. But when I need to access one of several other non-default databases, I keep receiving the "invalid table" error.
This runs fine:* (note that "fv" is the name of my database link)
v_query1 := 'select "ReleaseDate" from dbo.Schedules@fv where dbo.Schedules."SchedID" = :schedule';
EXECUTE IMMEDIATE v_query1 into rel_date using schedule;
I then take that rel_date variable, convert to a varchar2 (rel_date_char), and then use it as the database name in the next query...
This returns an error_ (Error ORA-00903: invalid table name)
v_query2 := 'select "PARTNO" from :rel_date_char.dbo.ProdDetails@fv where "SchedID" = :schedule and "UnitID" = :unit
and "MasterKey" = :master and "ParentKey" = :parent';
EXECUTE IMMEDIATE v_query2 into part_number using schedule, unit, master, parent;
I have also tried using all of the following to no avail:
'select "PARTNO" from ' || :rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || @rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from @rel_date_char.dbo.ProdDetails@fv where "SchedID"...
Is there a way to do this in PL/SQL?
Thanks for any help!

=> instead of executing the statement using "execute Immediate" we have to use PASTHROUGH package to pass the statement to the SQL Server.

Installing issues with Oracle Database 11g R1 on Red Hat Linux

Hi,
I am installing Oracle Database 11g on Red Hat Linux.
Version of the OS:Linux 2.6.9-5.ELsmp #1 SMP Wed Jan 5 19:30:39 EST 2005 i686 i686 i386 GNU/Linux
I have installed XManager on my PC to access the runtime installer in Graphical mode.
But once i click the installer file from Xmanager, it asks if the user wants to run it in terminal or simply run.
I selected the run in terminal and it starts the terminal where the initial pre-requisite checks are done i.e swap memory,temp and display.
The screen disappers and the graphical OUI never turns up...
Any pointer would be helpful.
Regards
Prabal

Try the following:
1. logon to the linux using root and issue the following command - xhost+
2. Open xterm in the Xmanager and logon to the linux using oracle user.
3. in the installation directory issue ./runInstaller.

Strange problem with an Oracle database link to SQL Server

Hi gurus,
Please help me on this problem.
We have an Oracle 10R2 database link to a SQL Server 2000 database. I can select count(*) from The_SQL_Server_Table@myOracleLink, and I can describe The_SQL_Server_Table@myOracleLink, but I cannot select Column1 from The_SQL_Server_Table@myOracleLink! I am getting the ORA-00904: "COLUMN1": invalid identifier error.
Could anyone tell me what is wrong here? By the way, the same user name can select all the columns in The_SQL_Server_Table through ODBC from the client app. But I need the DB link to work with some Oracle stored functions.
Thank you!

I have a SP in SQL Server which will return a Result Set.
My requirement is to call that procedure in ORACLE using DB Link and insert that resultset(Data) in the temp table.First you need to setup Oracle to SQL Server connectivity. To do that you can either use HS - heterogeneous connectivity which comes for free or use Oracle Transparent Gateway which is not free. HS uses ODBC, so if your Oracle database in not on windows, you'll have to get ODBC SQL Server driver for Unix/Linux (e.g. from EasySoft). Since SQL Server selecting from table function syntax is different from Oracle's you will have to, if you use HS, to use DBMS_HS_PASSTHROUGH package. I never worked with Oracle Transparent Gateway to SQL Server, so I don't know if and how it supports selecting from SQL Server table function.

Memory issue in oracle database 11g ...

Hi All,
I have installed oracle11gR2 on Linux (CentOS 5.5)... SErver has good amount of HDD - 669G and 16G RAM. I have two database running on this server.
I am getting out of memory error and end user also complains about dB is very slow... I have configured memory and SGA parameter in both the database and total allocation of memory and SGA maximum size 7.5G. So I assuemd that oracle database used RAM from whatever we configured in memory maximum parameter , in my case I have allocated upto 7.5G but when I run top command I can see almost 16G is in used and only few mbs left...
can anyone suggest me my assumption about memory allcoation to database is correct or not ? or when I allocated memory to database (using memory max parameter) then why top showing all memory in used. This is database server and no other process is running except oracle.
Thanks in advance...

Just enable AMM as below and forget the nitty gritties of setting lots of memory parameters ;-D
ALTER SYSTEM SET MEMORY_TARGET=6G SCOPE=SPFILE; --select the amount of memory as per your need

Performance Issues on Oracle Database Lite 10.3.0.3

Hello,
we have a big problem with one of our customers. He uses Oracle Database Lite in the standalone version. There are about 600 clients running a project with about 20 Publication Items. The customer works in the logistics field, so the Main time where nearly all clients want to sync and get their tours is from 02 AM to 05 AM, so that is the time with the most traffic.
Everything went well before last week. Suddenly the compose cycle needs (at least between that hours) about ten times longer than before. Normally we had about 40 - 80 seconds, now we have about 300 - 500 average with max values from over 1200 seconds.
Therefore we have a lot of conflicts and Disconnects on the clients. It is sometimes that bad, that nearly no client can sync successfully.
We checked our Selects in the publication Items, all are very fast and look good in the explain plan, so that shouldnt be the problem.
The installation is nearly in the Default state as oracle does when you install Oracle Lite. Are there any standard settings we can change? Does anyone had the same problem already?
The Machine is a Windows Server 2003 with an Intel Xeon CPU E7-4820 and 4 GB of RAM.
Of course our customer gets a lot of trouble because of that and we have to improve and fix that as fast as we can.
Any recommendation or opinions are very welcome.
If I have to give more Info about somewhat please feel free to ask, I will give it as fast as possible.
Thanks in advance

Hey,
many thanks for your proposals. The MGP runs every minute like the default settings are, because our application is a time sensitive. The data have to be very fast on the clients in the nights and thex are only a few minutes before available. I think the parameters are important in environemnts where the mgps runs only after a few minutes?
Let me summarize the situation since my las post:
We have days (nights) where everything goes quite well. Mainly that is thrusday and friday. But on the other hand, there are days where everything really is a mess.
The mgp caycles increase and when you look to mobile manager you see 70 clients syncing very very slowly (about 300 - 600 seconds) for just a little bit of data. Then we get the disonnects and the messages in the err.log.
What do you think, is this somehow network related, or ist this a logical problem in the Mobile Server itself?
Like postes earlier, there are 500 clients syncing against a standalone mobile server.
We just couldnt figure out, why the mgp times somehow and sometimes increase that much, that there are these problems.
First we thought, that they sync newly over wireless (GPRS or Edge) and that syncing is that slowly, that everything goes down, but arent sure. Is this possible because of the architecture of the Mobile Server? That a very slow network can slow down the mgps and that does timeouts and all the other stuff?
How many clients can a Standalone Mobile Server normally serve at same time without performance problems. What do you thin about the hardware I wrote? Is it powerful enough?

NCHAR issue with oracle database using JDBC adapter

Hi,
We have a requirement to develop an XI interface from FTP server(File adapter) to oracle database using JDBC adapter. In the oracle database table few fields are of type NCHAR/NVARCHAR. when we try to insert the character(A,B,c..) values into oracle table fields of type NCHAR/NVARCHAR, we are getting the following error message in the JDBC adapter audit log. IF we pass the numeric value to the same field, then we are able to insert the records successfully.
