Creating excel file on client machine using oracle pl/sql code

Hi All,
I have a situation where in i need to create an excel output file in my client machine, but using UTL_FILE i understood that i need to create the directory on server and i need to read and write on server itself.
Is there any other way where we can create a excel file other than oracle server, bcos this is used only once and there is no scheduler to execute on server.
Please do the needful.
Thanks,
Santhosh.S

The server should create the data set required by the client - do all the (intense) server processing that servers do well. This data set is then send to the client. The client is responsible for rendering that data set.. or saving it to the client machine storage if needed.
Within PL/SQL that is quite easy to do using the most common/standard client-server in use today - web based client-server.
The client is a web browser. It makes a call to the web server, that is serviced by a PL/SQL database procedure - a so-called web enabled procedure. It processes the request from the web browser, and returns a dynamic response. This response can range from HTML and XML, to video and image streams - and also CSV (Character Separated Values) data.
By default, most web browsers will use the local client spreadsheet application (like MS Excel) to open the CSV response received. Many web browsers will also provide an alternate option of saving that response as a CSV file (that can then be opened later using MS Excel).
Straight forward and basic client-server - and easily done using PL/SQL. Even easier done using (freeware) Oracle APEX (Application Express). APEX is a PL/SQL software suite that provides a web development system (only web browser required for development) and a run-time system to run the web application you have created.

Send email using Oracle Forms 6i through MS Outlook 2003

Try disable warnings:
Visual Basic 6 (VBA)
OlSecurityManager.ConnectTo OutlookApp
OlSecurityManager.DisableOOMWarnings = True
On Error Goto Finally
'... any action with protected objects ...
Finally:
OlSecurityManager.DisableOOMWarnings = False
If you find correct syntax with OLE2 post your code ;)

Using Oracle Database Express Edition in development environment

Hi All,
I have doubt regarding the usage Oracle Database Express Edition in Development environment. I am not sure weather I can ask a non technical question here or not. Pleas forgive me if I have done any thing wrong.
I am working in an IT company where we take up projects outsourced by our clients. As part of our current project we are making some modification to a web application used by an institution. Our client is using Oracle Data Base standard edition. Due to budgetary constraints of our Company we can not set up a Oracle standard edition data base in our development environment.
So would it be illegal if we use Oracle Database Express Edition in our development environment? We can guarantee that only our internal development team which comprise a maximum of 10 people will have access to this development database and this development data base will never be opened to our Client for their business purpose(Who have their own Oracle standard edition in their environment). As part of the project we delver only table DDL script and stored procedure to our client and they put it in their environment.The sole purpose of a internal Express database will be development only.
Could some one please tell me if it would be violation of license agreement if we install Oracle Database Express Edition in our development environment.

Hi Paul,
Actually I have already gone through the Oracle Technology Network Developer License Terms for Oracle Database 11g Express Edition . But was not quiet clear about the content. It says in the license terms that "We grant you a nonexclusive, nontransferable limited license to use the programs for: (a) purposes of developing, prototyping and running your applications for your own internal data processing operations". Does the term "your application" includes an application we are developing for another company. Since the Express database is installed in the development environment only and is not opened to any one else not even for Our client it definitely falls under the term "internal data processing operations" right?

Oracle Applications Implementation Wizard

I've installed using rapid install Oracle applications 11.5.10.2. I've read that implementing more than one module it can be much easier to use Oracle Applications Implementation Wizard. I've found documentation about this wizard but I cannot start it. Does it need to be seperatly installed after installing applications?. I do not have standard user wizard that should be created after installation of implementation wizard, also I do have only 2 roles containg word implementation
-Implementation System Administration
-Implementation Financials
do I need to install/configure extra product ?

One correction, there was installed user wizard, only the password was different then wizard. That user have assigned to implementation roles
-Implementation System Administration
-Implementation Financials
documentation of application Wizard describes following steops to launch the wizard:
1. Sign onto Oracle Applications using a user ID that has access to Implementation Wizard responsibilities. (You can use the predefine user Wizard, with password "Wizard.")
2. Choose any of the "Implementation" responsibilities.
3. Open the Application Implementation Wizard Startup window.
4. Using the Process list of values, choose the Wizard Implementation Process.
5. Leave the Context field blank.
When I open application implementation wizard get a window with tab
Functions / Documents / Processes
Goint to processes I cannot choose Wizard Implementation Process, from functions I can open Implementation wizard however in the next window "Select process group" there are no process groups, so I cannot go further.
How can I launch oracle implementation wizzard?

Is it possible to use Oracle Forms 10g with Oracle 10g Lite Database?

Hi All,
We are in process of migrating our forms from 6i to 10g environment.
We have two kinds of applications, one set run on general Oracle 11g database and the other set of forms run at the client machine using Oracle lite database.
We dont have any problem with Forms 6i to connect to Lite database as it allows to connect through ODBC:DSN names. When we try to connect to a lite database (10gR3) from Forms 10g through ODBC/DSN, it's not allowing and throwing the below error.
ORA-03121 : no interface driver connected - function not performed
Can someone tell me if there is something wrong in our approach? Also advise how to use Oracle Lite database with Forms 10G.
Sincerely,
Praveen Manthena

Hi,
I have experience with 6i with lite database 10g. There are two version of lite database one is multi language support and other one in english. There lang problem in connectivity with multi language 10g lite database. I done connectivity with single language connectivity of 6i with 10g lite database. You should try this one with forms 10g.

Forms6i Server (9iAS R1.x) loadbalancing using Oracle Web Cache

Hello,
I have read that it's possible to use Oracle Web Cache as a software load balancer between multiple Application Servers.
We are running Oracle9iAS R1.0.2.2.2a, with Forms/Reports6i servers on 2 Win2k boxes i.e our Forms6i application is deployed on two seperate boxes in two distinct locations. Users at each location, use their respective App Server url.
Since the application is the same i.e. Forms6i code/fmx is the same for both locations, I am looking into loadbalancing and failover capability that Web Cache might be able to provide.
So basically all users from both locations will point their browser to this Web Cache and the Web Cache will direct each connection to either of the two boxes. So, if either of the boxes dies, Web Cache will divert the requests to the other box.
My concern is whether Web Cache supports this for the Forms requests that it will receive from the users. We are using Servlet Deployment of Forms.
Has anyone done this or has any ideas as to whether it's going to work or not?
Thanks,
Manish

Manish,
we tested this but came across problem with Webcache that have to do with the jsession Forms uses. This is fixed for Oracle9iAS 9.0.2.x. So if you want to run Forms with Webcache in front, then please do this using the latest version of Oracle9iAS V2 Webcache. For Oracle9iAS V1 and Forms Services we recommend not to use Webcache but do the load balancing via JServ.

Can a C++ client use Oracle Standard or Oracle Enterprise version?

Can a C++ client use Oracle Standard or Oracle Enterprise version of Coherence or is the Grid edition required? Please keep in mind that I am only interested in doing what is legal from a licensing standpoint, even if some other options are technically possible.
Regards,
isailhobie

Yes, a C++ (or .NET) client can access a Coherence Grid regardless of what edition is licensed. In our parlance, this is called a "Data Client". A Data Client provides you access to data and services on the grid, for example with put/get/query, etc. A "Real Time Client" requires a Grid Edition license. Real Time Clients allow real-time synchronization with the grid; this enables continuous query caches, near cache, etc.
For a complete description of Coherence features by edition, including discussion of the three types of clients, please see http://download.oracle.com/docs/cd/E14526_01/coh.350/e14510/appfeatures.htm#BABIGHCF

Do you have a requirement to use MS-Outlook from the Client or simple send email to a list of recipients? If the requirement is simply to send email to a list of recipients, I suggest you use UTL_SMTP from the database to send your email rather than OLE to Outlook on the Users computer. Search OTN or the forums for 'MAILDEMO' and you will find many examples on how to send email from the database.
Hope this helps.

How to disable cache implementation in 8.1 SP6 for entity beans

How to disable cache implementation in 8.1 SP6 for entity beans
In our production environment, we want to disable cache implementation for entity beans. We are using weblogic 8.1 SP6.
Weblogic cache implementation has been causing many cachefull exceptions so we want that it fetches the data from database everytime instead of cache.

Check the "max-beans-in-cache" setting in your weblogic-ejb-jar.xml. The cache full exception, means that a new bean could not be created because of this cache being full.
Nothing to do with fetching from the database directly.
If you really want direct fetches then do not use beans at all. Consider using direct JDCB/SQL calls (without a entity bean) to fetch huge data.
Let's again review your application based on the below explanation before making a decision on which configuration change to perform:
If you truly have many ejbs simultaneously enrolled in transactions, then yes, the cache must be big enough to hold all the instances.
Your cache must have a max size large enough to handle your peak simultaneous transaction load.
Also, try to ask the following query to your application developer. Does every user actually have to have more than one bean in the cache ? Are many of these values read-only reference values that are not updated ?
SOLUTION CHOICE:
1. If you are testing with more number of users simultaneously, then you will need to increase the "max-beans-in-cache" setting in your weblogic-ejb-jar.xml to match the load.
2. If you have few users but still seeing a lot of beans, then consult with your application developer and try to ask the above questions (Does every user have more than......) and based on that try to redesign/tune your application to make it an effective Entity bean model.
3. If you have queries where huge result sets are returned, consider using plain/direct JDB/SQL calls.

Which Oracle client to use? with CRS2008 on Windows 2008 R2 64bit

Hi,
We are setting up a standalone Crystal Reports 2008 Server on Windows 2008 R2 64bit. This server will serve some reports that will pull data from an Oracle 11g DB. Several Oracle 10g/11g, (32bit or 64bit) DB client has been tried, but CRS cannot connect to the oracle DB using any of them. Which oracle client is known to be working well on this setup?
CRS 2008 <> Windows 2008 R2 64 bit <> Xeon E5600 series machine
Thanks,
Steve

Hello,
CRS2008 v1 supports Oracle 9.2, 10g R1, 10G R2 and 11g R1.
The client to use on those version are the same as the server meaning if you have a 11g R1 server then you can use an Oracle Net Client 11G R1. But you can use also a JDBC, ODBC, OLEDB Oracle 11G R1.
If you have a CRS2008 v0, then Oracle 11G is not supported. Only 9.2, 10g R1 and 10G R2.
I hope this will help you
Regards,
Philippe

How to uninstall oracle components silents using oracle universal installer in oracle client 11.2.0.3.0?

Hi,
I have installed oracle client 11.2.0.3.0 silently using the response file with INSTALL type as runtime. I want to remove 'Oracle sql developer' from the installed products. Using Oracle Universal Installer I am able to remove this component in GUI. Please provide me the silent switch to remove this component. I have tried with DEINSTALL_LIST property , but I am getting an error that 'no products selected for deinstall'. Please suggest on this.

Pl post your OS details
AFAIK, SQL Developer is not included in the Oracle Client install - it is a separate install. You will have to follow the instructions for uninstalling SQL Developer - check the docs for your specific version of SQLD - Oracle SQL Developer
e.g. for 3.1, see Installing Oracle SQL Developer

Connecting to Oracle 8.0.3 server using Oracle 10.1.0 client

I was wondering if it was possible to connect to a oracle 8.0 or oracle 8.1 server using oracle 10.1 client.
I have tried connecting to oracle 8.0.3 and it gives me an error saying "connections to this server are no longer supported."

If updating your Oracle Database isn't an option, then you can have 2 different clients installed (in different "Oracle Homes" (or directories), and use the selecthome.bat file to switch between your installed clients.
For example, before connecting to 8i, you'd run:
C:\Oracle\Client1_8i\bin\selecthome.bat
or this to use your Oracle 10g client:
C:\Oracle\Client2_10g\bin\selecthome.bat

How to use Oracle Client

Dear Buddies,
To the best of my knowledge I understand that Oracle Client is a minimal package to get connected to the Oracle Server in order to access the database. Corrrect me if I am wrong.
I have installed it based on the steps given in http://www.oracle.com/technology/tech/oci/instantclient/index.html
and also other sites.
How do I start using it? If SQL Plus, all I have to do is launch the SQL Plus, get connected and start using the database. How should I use this Instant Client? Please guide me. Is it compulsary to use it with SQL Plus? or some other tools?
I also tried the methods mentioned in this pdf http://www.oracle.com/technology/products/oraclenet/files/OracleNetServices_NetEasyConnect.pdf
but it doesn't help me as well.
Expecting your support and reply.
Thanking you in advance.
Alagu
Edited by: user645399 on Apr 29, 2009 9:22 PM

You need a client program that uses Oracle client to connect to an Oracle Database.
One such program is "sqlplus", it is the command line interface.
Its usage is described extensively in
http://download.oracle.com/docs/cd/B19306_01/server.102/b14357/toc.htm
See specifically
http://download.oracle.com/docs/cd/B19306_01/server.102/b14357/ch3.htm#sthref610
for how to connect to a database.
