Production environment with Oracle Database XE.

Hello, let me know which group members using Oracle Database XE in a production environment:
- Description of the business.
- Type environment: (Web, intranet or desktop).
- Programming language used.
- Performance.
Roberto.

We are using Oracle XE as point of sale backends.
Overall architecture:
- Cashier interacts with HTML GUI running in web browser in kiosk mode.
- GUI written in PHP served locally by Apache on point of sale unit.
- point of sale core logic is written in PL/SQL as packages in Oracle XE DB.
- currently, DBMS_JOB runs every 5 minutes to synchronize (push sales, pull data) with inventory server. (want to change to AQs so complete transactions are pushed in real time)
- sales reports, etc run from main Oracle Standard One Edition inventory DB.
Since each point of sale needs to run IE, Apache and Oracle XE we've found that 1GB of RAM is minimum that we can get away with and still have the system running well (cashier should never have to wait for anything; pressing any button on the GUI should react instantly even though it is IE making a local page request, Apache running a PHP module to serve the request, and calling PL/SQL to do the actual data change in the DB).
We've had XE go corrupt (strange errors, bad indexes, etc.) on us several times over the past 2 years. Fortunately in our case, we've never lost any data since sales are pushed to the main server which is backed up. Then, anything in the local XE database is expendable as we can rebuild it and pull back all information from the server. I've tried rebuilding indexes and such rather than completely rebuilding the database but have had no success (fixes for a few hours or a day but ultimately, the database continues to experience problems until the computer is rebuilt).

SAP BO Installation with Oracle Database

Hello all,
My client uses SAP R/3 with Oracle database. Now we have to install Business Objects on another machine.
I've read the documentation on Installing Procedures but there are some questions still not clarified.
1. Do I have to install Oracle in the new machine?
2. If not, can I connect BOBJ to the database of the SAP R/3 Server?
3. If I want to have three systems (Like in R/3, Productive, Tests and Development) do I have to install BOBJ in different machines?
Thanks in advance,
Regards

1. you dont have to insall Oracle database at the BO machine side, you just need any database to hold the BO repository.
2. you cant connect directly using BO, only Crystal reports can connect directly to R3 database, you need to have a BW in between.
extract your data into the BW, and let BO connect to BW using the BO integration kit for SAP solutions.
3. no you dont have to have 3 different machines, using one BO machine you connect to them all, but you may need build a BO environment, (Development, Production servers)
good luck

Does Oracle OLAP comes with Oracle Database 10g ?

1.Does Oracle OLAP comes with Oracle Database 10g or do we need seperate software to have this ?.
2.If I create a Cube with Analytic work space manager the cube is going to be stored in the Database ( meaning the in the table space where OLAP is Stored).
3. What is the difference between Analtyic work space manager and discoverer For Olap.
Help is higly appreciated ..
Thanks, Prasad

One thing to point out : The OLAP option is a costed database option, so while this is automatically installed and part of your database you do have to purchase additional licenses to use this feature. You will need to check with your Oracle account manager to see if you are actually licensed to use this feature.
If you have existing 9i OLAP cubes these can be quickly and easily migrated to 10g OLAP and the documentation explains how to do this. However, there are many new features that are part of 10g OLAP that will improve the performance of your data model that will not be enabled as part of a migration process. Based on my experiences it would be quicker and easier (depending on the size of your existing 9i OLAP cubes) to consider rebuilding your data model using these new 10g features. You should be able to export all the dimensions to XML templates from 9i OLAP and import the templates into the 10g schema and reload your dimensions.
For the cubes you will probably want to consider using partitioning, composites and compression to provide maximum flexibility and performance for your new data model. There is more information on these features within the OLAP documentation and in the many whitepapers and presentations on the OLAP home page on OTN.
For moving data from SQL Server to 10g OLAP much depends on the nature of the data transfer. If it is a one-off bulk data load then you could consider using the normal MS command line tools to dump the data out and transfer it to Oracle. Alternatively, you could consider using Oracle Data Integrator to manage the extraction of the SQL Server data and the data load process into Oracle 10g relational tables. If you decide to use Data Integrator this will require additional licenses.
If you can extract the data from SQL Server to flat files you can use Oracle Warehouse Builder (basic ETL is free as part of the 10g database license) to load that flat file data via external tables. Warehouse Builder can also be used to define your OLAP data model (think of Warehouse Builder as a more powerful version of Analytic Workspace Manager) and provides tools to load the data directly into your OLAP dimensions and cubes. You can get more information on managing OLAP data models with Warehouse Builder the Warehouse Builder home page on OTN.
There are no facilities to modify Discoverer Viewer to add customisations. You can add company logos, modify certain colors and/or hide certain features but it is not possible to add additional features. You may want to consider using BI Beans to provide this type of environment. BI Beans is the development framework used to create Discoverer Viewer. You can create customised JSP pages that look identical to Discoverer Viewer pages with the added benefit of providing your own specific features. You can get more information on the BI Beans home page on OTN.

Problem with Oracle database Express Edition (Linux)

I installed oracle-xe on my machine (ArchLinux x64), and all worked fine before a reboot. After it, I still can connnect to the db with sqlplus, but can't connect to apex (http://localhost:8080/apex/f?p=4950) and can't get a connection using ojdbc:
Exception in thread "main" java.sql.SQLRecoverableException: IO Error: The Network Adapter could not establish the connection.
I tried to reinstall the db several times, but the result was always the same: all is ok only before rebooting. I'm a newer with Oracle database and can't find a solution. Could you give me some tip about it?

The problem was solved by changing permissions for log directory :
sudo chmod -R 777 /usr/lib/oracle/product/11.2.0/xe/log

Memory consumption is more with oracle database compared to Sybase

Hi,
We are executing the same java source code with backend sybase and the oracle database. But with oracle database it is consuming more memory than Sybase.
Currently using 11g R2 with ojdbc6.jar driver
can you please provide the information to optimize the memory consumption when using the oracle.
Thanks,
Nagaraj

What memory in Oracle? Shared pool? Buffer cache? PGA? UGA? Library cache? Something else?
What memory in Sybase did you compare it to?
What type of client-server connection to Oracle was made? Dedicated or shared?
What commands/method were used to determine the memory consumption in Oracle and then Sybase?
What serves as the baseline for comparison?
Comparing product A with product B is a COMPLEX thing to do. And IMO, beyond the abilities of the majority of developers - as they lack the technical expertise to extract usable metrics and correctly compare these between products that can work VERY differently.
And unless you can provide technical details to backup your claim that you are observing that "+Memory consumption is more with oracle database compared to Sybase+", I would say that you have no idea what you are actually observing and in no position to deduce that Oracle consumes more memory.

OIM 9.1.0.1870.1 with Oracle database 11.1.0.7 - Hung threads

Anyone seen issues like hung threads using OIM9.1.0 with Oracle Database 11.1.0.7?

Thanks guys for the quick responses.
But I have tried both the options for putting the jar in Third Party and also by uploading using the OOTB utility UploadJar.sh.
But it is giving the same error.
I have tired rebouncing the server and also Purge cached, but no success.
Just to mention again, I have tried with all the last 3 postgres JDBC4 driver available on the site (u mentioned).
So, any other clue?
Thanks in advance.

but when i am running the same thing in win 7 64 bit. it's showing login error.
not going to home page even i checked with this published file open in visual studio it's working fine.
how to run it correctly?
thanks in advance.

The number of times you have been asked to post sufficient details for your questions, we would expect you to have got the message by now... but clearly not.

not going to home page even i checked with this published file open in visual studio it's working fine.
how to run it correctly?No code, no database version, no details...... = NO HELP.
When are you going to learn.

Upload file in JSP with Oracle Database 10gR2

How to upload file with oracle database 10gR2??
i can't find how to upload..
i've tried to create a procedure in oracle and execute in netbeans but the file save in directory and then from directory save to database.
it means the file save in 2 location, in directory and database..
does anybody know how to save file direct from the JSP file into database without save in directory?
this is the procedure..
create or replace PROCEDURE load_file (
p_id number,
p_photo_name in varchar2) IS
src_file BFILE;
dst_file BLOB;
lgh_file BINARY_INTEGER;
BEGIN
src_file := bfilename('DIR_TEMP', p_photo_name);
-- insert a NULL record to lock
INSERT INTO temp_photo
*(id, photo_name, photo)*
VALUES
*(p_id , p_photo_name ,EMPTY_BLOB())*
RETURNING photo INTO dst_file;
-- lock record
SELECT photo
INTO dst_file
FROM temp_photo
WHERE id = p_id
AND photo_name = p_photo_name
FOR UPDATE;
-- open the file
dbms_lob.fileopen(src_file, dbms_lob.file_readonly);
-- determine length
lgh_file := dbms_lob.getlength(src_file);
-- read the file
dbms_lob.loadfromfile(dst_file, src_file, lgh_file);
-- update the blob field
UPDATE temp_photo
SET photo = dst_file
WHERE id = p_id
AND photo_name = p_photo_name;
-- close file
dbms_lob.fileclose(src_file);
END load_file;

Well your Oracle procedure is designed to load a file, so that's what it does. If you want it to load from a data stream such as an upload, you need to rewrite it accordingly.
So far this is not a Java question at all.

Does Analytic Workspace Manager 11.2.0.3.0A work with oracle database 12c?

hello,
i would like to know if AWM 11.2.0.3.0A works against with oracle database 12c in pdb mode or not .
regards
jm

I have attempted to connect 11g versions of AWM to 12c and get this error:
'This version of Analytic Workspace Manager is incompatible with the database instance. The Analytic Workspace Manager version is 11.2.0.3.0 and the database compatible version is 12.1.0.0.0'
So unfortunately it is not compatible, and there is currently no AWM for 12c
I also contacted Oracle support and they wont give me any information about a release date or any information on the xml template specification for 12c.
I guess we will just have to wait till they release a version of AWM that supports 12c...

ASP application has problems working with oracle database 8.1.7

ASP application has problems working with oracle database 8.1.7 through both oracle ODBC driver and Microsoft ODBC driver
We have an ASP application running on Windows 2000 server, and with 8.1.7 Net8Client and MDAC 2.6 SP1.
The application worked fine with an Oracle 8.0.5 database.
After upgrading oracle database to 8.1.7.0.0, our ASP application works fine except when updating the same data record more than once. The application is not saving our updates.
We tested our application using Oracles ODBC driver v8.1.7.5.0
and experienced more problems. We had problems just bring up our data entry pages. In either case, we are returned with some 505 errors in our browser, problems with the ASP pages and IIS, the page is not displaying.
If anyone has some suggestions on how to fix my problem, please advise. Thanks in advance.

thanks...i saw one article with this approach..but the document did not present the detailed process...do you have one? i am still searching for a good procedure to follow...since it is an old database and focusing/studying old versions like this is a pain in the a**... :(

Problem with ORACLE database

Hi all,
I am facing some problem with ORACLE database while configuring one JDBC scenario in the receiver side. I have configured one JDBC scenario like FILE TO JDBC. As JDBC is at receiver side i have provided the input file with the following format ,
<root>
<StatementName1>
     <dbTableName action="INSERT">
         <table>employee</table>
          <access>
                <flag>NO</flag>
                <ID>567</ID>
         <NAME>134</NAME>
             </access>
     </dbTableName>
</StatementName1>
</root>
But in the ORACLE database all my columns are in the uppercase.
So when i have tried to send this input file to process through JDBC receiver side then i have faced the below error :
FATAL ERROR: Column 'flag' does not exist in table 'employee'
Then I have tried to check with sender side processing of JDBC adapter. By using the SQL statements as
SELECT * FROM EMPLOYEE WHERE flag='NO'
UPDATE EMPLOYEE SET Flag='YES' WHERE flag='NO'
Here it worked fine.
Now my question is,
If the same adapter is working when we are writing a query directly(sender side), then we must also allow case independence in the auto generated SQL part(receiver side).
The JDBC drivers for both SQL server and Oracle, supports the same java code, for accessing the DB, irrespective of the case of the column names.
Please clarify this doubt as soon as possible.
Thanks,
Soorya.

Hi Dharmaveer,
When I go with the following input file,
<root>
<StatementName1>
     <dbTableName action="INSERT">
         <table>EMPLOYEE</table>
          <access>
                <FLAG>NO</FLAG>
                <ID>666</ID>
                <NAME>SSS</NAME>
             </access>
         </dbTableName>
</StatementName1>
</root>
I will get the following query with succesfull processing.
INSERT INTO EMPLOYEE (FLAG, ID, NAME) VALUES (NO, 666, SSS)
when i go with this input file,
<root>
<StatementName1>
     <dbTableName action="INSERT">
         <table>EMPLOYEE</table>
          <access>
                                <flag>NO</flag>
                               <ID>777</ID>
                    <NAME>TTTT</NAME>
                    </access>
               </dbTableName>
</StatementName1>
</root>
Then i am facing this problem,
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'EMPLOYEE' (structure 'StatementName1'): java.sql.SQLException: FATAL ERROR: Column 'flag' does not exist in table 'EMPLOYEE'
Here I cant get any SQL statement as it is not successfull.
I have gone through your link but it also says to modify the column in the input file which is not possible for me. Can you please help me in this regard?
Thanks,
Soorya
