Gridview against an Oracle DB

Hi,
Is there an example, for that we call an event in the code-behind to do some updating in the Oracle DB and it's triggered by that Updatecommand of the Gridview?

Hi,
Have you had a look at Oracle Database Express Edition http://www.oracle.com/technology/products/database/xe/index.html ? This is a lighter-weight Oracle DB which may do the job for you.
Regards,

Running Oracle 9i client code against an Oracle 10g install on PC

On Unix I am able to run Oracle 9i client code against an Oracle 10g install by setting ORACLE_HOME to the Oracle 10g install location and then creating a symbolic link (example: ln -fs libclntsh.so.10.1 libclntsh.so.9.0).
On PC (in particular XP SP2) I want to do something similar without using "junctions" or "junction points". Is there a way to set an environment variable or ini file to have my 9i client code point to the right libraries? I keep getting an error saying that my client code will not run due to "orasql9.dll" not being found. The "orasql10.dll" is installed on my machine.
Any assistance would be appreciated.

You might want to check metalink doc,
Client / Server / Interoperability Support Between Different Oracle Versions
Doc ID: Note:207303.1
Even your application built on 9i, doesn't mean it will not work with 10g database. From what I can see, running 9i executable under 10g installation to create mixed blood breed will do more harm than good. Not only it's not supported but also the outcome is unpredictable.

Oracle Forms 6i client/server against an Oracle 10gR2 database

Hello
We have the following situation:
Oracle Forms6i/Reports6i client server application against an Oracle 8i cost-based database. we want to migrate this application
step 1:
Migrate the database to 10gr2, but do not touch the client application
Go live
step 2:
Migrate the development environment to 6i webforms.
Production environment stays client server.
With this construction we can still create new patches/functionality.
step 3:
Migrate to Forms10gR2 (and reports)
I know Forms 6i is not supported anymore.
My question is on step 1.
When I read NOTE: 338513.1 entitled "Is Forms/Reports 6i Certified To Work Against Oracle Server 10g Rel 1, Rel 2 or 11g?" carefully
it says that Forms 6i is not certified against 10gR2.
On OTN I read several posts that this works ok (assuming you do not use the wrong character set).
I also read on OTN that patch 18 (which is only supported for EBS customers) is certified against 10gR2.
The questions:
- Is Oracle Forms patch 18 certified against an Oracle 10gR2 database? (or only for EBS)
- Is there anybody out there that can confirm that Oracle Forms 6i C/S works against Oracle 10gR2
Regards Erik

Thank you.
Now I found it.
But how do I read that page.
It says:
Client Certifications
OS      Product      Server Status
XP      6.0.8.27.0 Patch 18      N/A      Desupported
Application Tier Certifications
OS      Product      Server      Status
XP      6.0.8.27.0 Patch 18      9.2      Desupported
XP      6.0.8.27.0 Patch 18      10g      Desupported
I read this as follows:
Patch 18 was certified agains a 10g database in a webforms environment.
No client server mentioned and Server 10g , so no 10gR2!
I'm I right?
Regards Erik

Question on using a Parameter against an Oracle date field

Post Author: klkemp100
CA Forum: Data Connectivity and SQL
newbie here just getting started in Crystal Reports v11.0
writing a report to go against an oracle view. i need the report to use a parameter that the user enters to select a specific date.
i went through the database expert and keyed in my own sql since i first tested this via TOAD and know that the sql works fine with a hard-coded date etc.
next i created a parameter and set it first up as a DATE but got the message that FAILED TO RETRIEVE DATA FROM THE DATABASE, even though I know that there is data to retrieve and i have previously retrieved it when the selection date is hard-coded in the query.
i then changed the field type in the view to be a VARCHAR2 and changed the parameter to be a STRING, but am still getting the same thing.
is there something special about using dates and parameters within crystal against oracle?
thanks in advance for your help.

Post Author: amr_foci
CA Forum: Data Connectivity and SQL
you also may check the date format , oracle maybe excpecting you to send the parameter in some format and you are sending it into another format
if both are type dates in report and database you can use this
where to_date(to_char(mytable.my_date_field,'dd/mm/yyyy'),'dd/mm/yyyy') = to_date(to_char(,'your_format'),'dd/mm/yyyy')
you may use this in a free hand SQL
good luck

Running HTMLDB against another Oracle Instance

I have an HTMLDB dashboard onto our system and would like to be able to run it against a different Oracle instance. Ideally would like to be able to choose the instance on the login screen. Currently we have to setup dblinks to each of our instances and then customise the application to select from the relevant instance. Any ideas?

AFAIK, Golden Gate has no requirement on Oracle edition to be used, but could have licence cost differences.
It works on Oracle from version 8i to the latest one, not only on Oracle database, and not only between same Oracle version and same OS, and not only between two Oracle db .

How to change field size using SQL against an oracle Database

I am an admitted novice user, looking to become more proficient.
I have a field in a table that I need to expand the field size. The table is called Inquiries. The data type is text. The current Field Size is 10. I want to increase it, to either the max, or somethign long enough to fit TECHNOLOGY LEADERSHIP PROGRAM.
What is the SQL command to change the field size, and what is the max for a Text Field Size

And/Or, an even better question might be,
Do I need to use SQL*PLUS to do this, or are there better tools. I.e, I like how in Access, you can open up a database in Design view and just change the amount for the field size. Is there a similar "easy" method to do something like that with an Oracle database.
My current version of the server/database is:
Connected to:
Oracle9i Enterprise Edition Release 9.2.0.6.0 - Production
With the Partitioning option
JServer Release 9.2.0.6.0 - Production
I was thinking I had to do SQL commands to perform the action, but there may be another way that I am not thinking about with all of the tools at my disposal. When I installed Oracle on my desktop, I installed most of the management tools and networking services, if that helps

Can you use SQL Developer against non Oracle data bases?

If so, then how do you define the connection for non Oracle data bases?

Look, SQL Developer has got to be a 'gateway' into Oracle DBs from other databases. JDBC allows simple introspection and execution of SQL commands. So the 'explain' button won't be available, or some of the DDL stuff, big deal! Let them get a taste of what they are missing by not having an Oracle database.
If we can get non-Oracle developers (especially MS SQL Server) to use SQL Developer it will expose them to the superiority of the Oracle DB server.
If they have heterogenous services installed they are already an Oracle customer -- we have little additional DB server sale opportunity there. SQL Developer is a really sweet tool and it could be a real draw into the DB server sales.
SQL Developer must be easily usable by non-Oracle customers in order to help us sell the DB server to them!

How to use DB connect against secondary Oracle DB ?

Hi all,
this is the issue:
an existing BI 7.0 based on Oracle 10.2.0.2.0 has to acquire data from an external Oracle 9.2.0.6 database. We want to use DB connect functionality.
1st Q: are the existing components (DBSL and Oracle db-client) sufficient for interfacing to the secondary database?
2nd Q: would it be better practice to look at the external database as a completely separate one? which means to install separate DBSL and db-client for it.
Unfortunately neither online documentation nor SAP notes provide full clarification. Is there any experience in the field? all comments and contributions are warmly appreciated!
THX, Harry

Still puzzling on that issue. Will come back when completely solved. /hs
OK, gurus, expertz and those to be, here's the story:
BI 7.0 component of SCM-APO (Oracle 10.2.) is successfully connected to remote Oracle 9.2.
Actually there have been just a couple of points to look after. First thing was to maintain the alias connection string in tnsnames.ora file. Plus this file is required twice, in the ORASID directory as well as in the <SID>ADM directory.
Next issue is that apparently Oracle 'grants' are not supported by DB-Connect. But at least there is BI support package 11 which enables us to connect to other users' objects (different user than DB-Connect user). This healed the grants issue.
Further topics have been the date conversion issue (this should already be done in the remote source DB) and name length and characters-2-B-used requirements.
Once again thanks for your contributions and happy computing!

Slow query against seg$ - Oracle 10g

Hi,
Our AWR report shows the following slow query, 3 minutes per execution,
select file#, block# from seg$ where type# = 3 and ts# = :1
This query isn't from our application for sure. Does anyone know what backgroud jobs or processes may execute this query?
Thanks.

It looks like the type of thing the SMON would run to clear up temporary segments after a process has done a rebuild, move, drop or similar. One reason why it might be slow is if you have a very large number of objects in a given tablespace that is subject to a lot of drops, creates etc. (E.g. a tablespace holding a complicated composite partitioned object with lots of indexes that goes through a frequent cycle of add/drop partition).

SQL Developer 3.0 against Oracle 10g

Hi,
I have used SQL Developer in previous employments and prefer use it now (ie SQL Developer 3.0), but unsure if the mix will work.
I am on a Windows Server 2003 Std 64bit Edition and with Service Pack 2. and have Oracle client 10g home with basic tools against an Oracle 10G database server.
So before installing, I would like some tips on the best mix for Client and Server with respect to SQL Developer.
I also understnad that it will require Java JDK install prior to SQL Developer. Will this require me to take into consideration current Java installs under
"C:\Program Files (x86)\Java\jre6\bin" and dated back to 30 Sept 2010
Many thanks before hand
Chris

You can can download SQL Developer with a JDK included. This is 32-bit, but will run fine in a 64-bit OS.
Alternatively you can download the 64-bit version of SQL Developer. This requires you to have a 64-bit JDK.
You can install multiple JDKs without interfering with each other. Your existing JRE installation won't work anyway as you need a JDK.
If you download a JDK, don't get Java 7 as SQL Developer doesn't work properly with that. Get the latest version of Java 6.

Oracle 10g Reports Server - problem authenticating against DB

I have a problem with Oracle 10g Reports server authenticating against an Oracle RDBMS.
When I try to run reports, an authentication form screen is presented, with the password field empty (the URL in explorer that loads this page contains the username and DB instance, but is missing the password) and the following error message:
REP-51018: Need database user authentication
When the password is entered into the empty field in the form and submitted, another 2 authentication errors are given.
REP-51018: Need database user authentication
REP-12545: java.sql.SQLException: ORA-12545: Connect failed because target host or object does not exist
When the URL in the browser location field is manually altered to include the DB password, the reports are authenticated fine.
Any ideas which config file I should be looking in?
Any pointers would, of course, be much appreciated.
thanks,
Brian

Hello, i finally have discovered what was happening, it has to be with the way FreeBSD passes the password field. By default FreeBSD passes the password field with a '*' while Oracle Linux (and Red Hat clones) expect an 'x' to look into shadow maps (Linux uses the '*' character in the password file to not allow login to that user).
To solve it the password field served by the NIS server must be substituted, which is accomplished with nsswitch.conf and adding a line to the /etc/password file on the NIS Client, so the final files will look this way:
# nsswitch.conf (compat directive allows us to use the '+' sintaxis in /etc/passwd file)
passwd files compat
# /etc/passwd (just add at the end of file)
+:x:::::

Running GoldenGate against Oracle 11g Standard Edition?

We're looking to run Oracle GoldenGate against an Oracle 11g Standard edition database to another Oracle 11g DB also on Standard. I've been reading though the documents and they talk of Oracle to Oracle using XStreams which is part of Streams. But it's my understanding that Streams is only available on Enterprise.
So is it possible to run GoldenGate on Oracle DB Standard Edition?

AFAIK, Golden Gate has no requirement on Oracle edition to be used, but could have licence cost differences.
It works on Oracle from version 8i to the latest one, not only on Oracle database, and not only between same Oracle version and same OS, and not only between two Oracle db .

Custom PWS (Java) against Oracle

We are planning on developing a custom PWS in Java against an Oracle database (Peoplesoft).
We will be deploying Websphere App Server 5.1 with EDK 5.1 (Java) on the remote (portlet/web service) server on the Windows platform.
Is there any peference/recommendation as to which JDBC driver(Data Direct driver, type etc.) , I should use to access the Oracle database from teh custom PWS? Does anyone forsee any issues with this platform and/or Oracle database access on the remote application server.
I'd appreciate any JDBC driver specification recommendation and any other insights into this.
Thanks and regards.

Try this (refers to assignment service, but I believe classpath is the same):
32.3.2.3 How to Deploy a Custom Assignment ServiceTo deploy a custom assignment service:
1.Use one of the following methods to make an assignment service implementation class and its related classes available in the class path of Oracle BPEL Process Manager:
◦Load your classes in SCA-INF/classes directly or SCA-INF/lib as a JAR.
◦Change the Oracle BPEL Process Manager shared library to include your JAR files.
Note:
◦You cannot create different versions of the assignment service for use in different BPEL processes unless you change package names or class names.
◦Java classes and JAR files in the suitcase are not available in the class path and therefore cannot be used as a deployment model for the assignment service.
◦The steps must be repeated for each node in a cluster.
