JBCL 2.0 and Oracle 8.0.5 Objects Option

I4m working with JDeveloper 3.1.1.2 using JBCL components and Data Express to connect to an Oracle 8.0.5 database with Objects Option.
I use a valid SQL like :
SELECT C.DENOMINACION AS DENOMINACION, C.OBSERVACIONES AS OBSERVACIONES, C.FECHA AS FECHA, C.CONSOLIDADA AS CONSOLIDADA, C.COBERTURAS.NOMBRE AS COBERTURAS, C.ES_DE_UN_TIPO_DE_CONVOCATORIA.DESCRIPCION AS TIPO FROM ELE_CONVOCATORIA_ELECTORAL C
QueryDataSets work fine and they return references to objects as they were another column of the dataset but when i try to get data inside them through something like:
queryDataSet1.getString("COBERTURAS");
i receive:
borland.jbcl.dataset.DataSetException: Unknown column name: COBERTURAS
I can4t even count the number of columns, i always get '0' but the queryDataSet shows me in the design panel all the columns correctly.
Does exist any documentation about what4s happening?
Must i look for a newer version of JBCL or redoing all the work?

jdev 3.1.1.2 is designed to work with rdbms 8.1.6, so it provides the rdbms 8.1.6 jdbc drivers with it.
Since 8.1.5 came out, it has been a known issue that you can not use jdbc 8.1.x jdbc drivers to access oracle 8.0.x objects with them.
Check the notes section at the bottom of table "Table 2-1 JDBC Driver-Database Compatibility " in thefollowing topic :
"Requirements and Compatibilities for Oracle JDBC Drivers" located at :
http://otn.oracle.com/docs/products/oracle8i/doc_library/817_doc/java.817/a83724/getsta1.htm#1008206
by the way --
rdbms 8.0.5 went out of support on dec 31, 2000.
i recommend you upgrade to oracle rdbms 8.1.7 ...
i hope this helps ...

GeoMedia and Oracle 8.1.6 Object Model

Can anyone tell me where I might find the patch for Oracle 8.1.6 which clears up the following error:
SQL exception encountered:
Reason: ORA-06512: at "MDSYS.SDO_TUNE", line 1834
this is due to the use of any SDO_TUNE function (like Estimate_Tiling_Level)

Werner,
I assume that you are referring to the Oracle patch refenced in the GeoMedia documentation where there is a problem with spatial filters and all SDO_TUNE functions. I inquired about this with Oracle back in January and the patch you are looking for is available on Metalink.
Oracle support instructed to search for ID 5461.999 you will find patch 08_07. Please make sure you read and follow the Readme link available with this patch. I downloaded the patch (i.e. NT816-000807.zip) but never installed it because the problems have been corrected in Oracle Spatial 8.1.7. I tried to do a search again just before sending this but didn't come up with anything so you might have to submit another TAR with Metalink to find it. I still have the zip file so if you come up blank I may be able to get it to you across an FTP if available. Good luck.

Select query differences between oracle 9 and oracle 8.

Hi,
I have a problem using the select query between oracle 7 and oracle 9i I don't have the same result :
ex:
With oracle7
SQL> select 'champ1','champ2' from DUAL;
'CHAMP 'CHAMP
champ1 champ2
With Oracle 9
SQL> select 'champ1','champ2' from DUAL;
'CHAMP1' 'CHAMP2'
champ1 champ2
So Can someone tell me how to solve this problem ? Is there a parameter in oracle 9 to set?
Thanx.

Whenever you are posting anything over internet forums like this - you should be very careful about not just posting the details which requires to solve the problem - also should be sensible about your question.
This is not at all desired when you are posting such question. It may be because - you may not well aware of the fact.
My suggestion is -> First Go through the basics Of SQL in general.
Then go for any specific product like Oracle/ SQL Server/ Sybase etc.
And, finally learn the advanced commands of that DB.
You asked it - may be you thought the difference in output in terms of lines. But, that is not your actual output. That is the graphical display part only.
Anyway,
You can get the quite familier output by first type the following command ->

Oracle Single Sign on and Oracle Internet Directory

Hello Gurus,
What is the relationship between Oracle Single Sign on and Oracle Internet Directory.
To my understanding, OID is required to install SSO.
If OID already exist, can we just install SSO and go on integrating it to existing OID.
Great Thanks,

Hi Tim,
I've been working on this and could reproduce the issue with anonymous binds. A fix will be ready in 4.2.1.
So what I really need is the password used for login to pass to the is_member call.The P101_PASSWORD item does not save state. However, you can access the value during submit processing of the login page, for example in the post authentication function of your authentication scheme. People sometimes put code in there to query the user's groups (e.g. with apex_ldap.member_of2) and save them in an application. This item value can then be used in the authorization schemes.

Oracle Spatial and Oracle Forms

Hi,
Does anyone have experience with Oracle Spatial and Oracle Forms?
I have generated a form, which is based on a view. The view uses the mdsys.sdo_relate operator. Somehow I am unable to get the form to perform (to get one record it takes over 20 minutes). While useing sql-navigator to process the same statement it seems no problem. The query that also uses the view, is then processed in 10 seconds.
I also noticed that when text-functions like ' lower' of ' upper' are used to query the view, the query is processed within 15 seconds. If I don't use ' lower' or ' upper' it takes a long time (> 20 minutes) to process the query. Is it possible that this causes the bad performance of the form?
On metalink I have found that forms and spatial do not cooperate because of the pl/sql version that
forms6 uses. There is no solution presented, does anyone know of a work around?
My configuration is:
Oracle 8.1.7 on WIN2K @ PIII-800Mhz 256 Mb memory.
Formsbuilder 6
If requested I can post the queries that I have made.
With regards,

Limitation on SQL executing select statement from ADO and Oracle 8.1.7.1 OleDB Driver

Hi,
we are running a query with a big dunamic select statement from VB code using ADO command object. When Execute method is called system hangs and control won't return back to the application. it seems to be that there is some type limitation on Query string length. Please tell us if there is any?
we are running Oracle 8.1.7 Server on Windows 200 Server and connecting from a W2K professional, ADO 2.6 and Oracle OLEDB 8.1.7.1 OLEDB Driver.
Sample code:
Dim rs As ADODB.Recordset
Dim cmd As ADODB.Command
Set cmd = New Command
With cmd
.CommandText = ' some text with more than 2500 characters
.CommandType = adCmdText
Set rs = .Execute
End With
when i debug using VB6 and when .Execute line is called system hangs or return a message method <<somemethod> of <<some class name>> failed error.
Any help is appreciated.
Thanks,
Anil

A stored procedure would only slow you down here if it was poorly written. I suspect you want to use the translate function. I'm cutting & pasting examples from the documentation-- a search at tahiti.oracle.com will give you all the info you'll need.
Examples
The following statement translates a license number. All letters 'ABC...Z' are translated to 'X' and all digits '012 . . . 9' are translated to '9':
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'9999999999XXXXXXXXXXXXXXXXXXXXXXXXXX') "License"
FROM DUAL;
License
9XXX999
The following statement returns a license number with the characters removed and the digits remaining:
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '0123456789')
"Translate example"
FROM DUAL;
Translate example
2229
Also, LIKE '%<string>%' is going to be rather expensive simply because it has to compare the entire string and because it forces full table scans, rather than using indexes. You could speed this sort of query up by using interMedia Text (Oracle Text now in 9i). If you can eliminate one of the '%' options, you could also improve things.
My guess is that your stored procedure is inefficient and that's causing the problem-- 5k rows per table should be pretty trivial.
If you post your query over on the PL/SQL forum, there are better performance tuners than I that might have more hints for you. To get really good advice, though, you'lllikely have to get at least the execution plan for this statement and may need to do some profiling to identify the problem areas.

New to XML and Oracle

Just trying to clarify some issues as I try and learn about XML, and specifically how it integrates into the DB.
1 - Is there a way with Oracle tools for me to get an XSD of an existing 9i relational schema? We are not currently using the XML DB, but our middleware developers would like to have an up to date XSD to use for their internal mapping.
2 - Is there any way that I can keep that XSD up-to-date automatically, so I get a new one whenever the schema gets updated?
3 - If I wanted to investigate storing XML docs within the DB in native XML format, I need to have an XML DB, correct? Is this DB construct maintained seperatelly from my "normal" relational schema? or are they kept in sync by Oracle?
I know these may all be real basic questions, but as I said, I'm new to XML and Oracle. I am reading as much as I can, but there are a lot of docs out there.
Thanks,
Mike

Hi
1. On my opinion such a tool doesn't exists. Some parts can be implemented elsewhere, but not as described by you... e.g. with XSU if you specify the parameter "withschema" the XSD of the executed statement is generated. Another example is to use DBMS_METADATA to dump the data dictionary in XML (but not XSD, of course you could write your own XSLT to do this transformation...).
2. -
3. If you use XSD-based tables the XSD and the relational model are stored separately in the data dictionary. Therefore if you change the XSD you have to drop/create the XSD-based table... no schema evolution yet.

SRM 4.0 Installation Master and Oracle Installation

Dear Members, I am trying to install SRM 4.0 in sandbox using the SRM 4.0 Installation Master DVD. The question I have is does this installation take care of Oracle Installation also or should I install Oracle 9.2 first and then use the SRM Installation Master DVD to install the SRM.

Problem with Java 5 and Oracle 10g JDBC driver

Hi All,
Currently we upgrade our web application to Java 5 and Oracle 10.2 JDBC driver. And we encountered a bug, when the user entered the information through UI and data didn't store into database (Oracle 9i). The problem is that this bug is not happend so often maybe once a day and this did not happen before we upgraded to Java 5 and Oracle 10.2 JDBC driver. Does anyone encounter the same problem ? Is this Java 5 problem or Oracle JDBC driver problem ?
Thanks,

sounds like a database problem...
Are you using a driver version that's supported for your database engine?
What else did you change? We once ran into a major bug in our application that had for 5 years been masked by performance problems in our hardware and infrastructure.
Once those were resolved the bug showed itself and caused tens of thousands of records to be erroneously inserted into our database every day.
It's certainly NOT a problem with your JVM (if it's a decent one, like the Sun implementation).
So it's either your database, your driver, your network (dropping packets???), or your application.
The upgrade may just have exposed something that was already there.

Problem with installing Oracle UI and Oracle SP (ouiosp220160.jar)

Hello,
I have downloaded the installation file for Oracle Universal Installer and Oracle Software Packager which is in the form of a jar file:
ouiosp220160.jar.
WhenI try to extract it, the JVM says that the jar file is a corrupt one.
So, I downloaded it again and still it is a corrupted one.
What to do now? Is it in the corrupt form on the site or I am missing something?
Any other mirror site?
Please help.
-Sameer

Yes use a different ORACLE_HOME's for the Database,
The Application Server (Needs 2 Oracle Homes if you are installing it on one server) and the developer suite - I would expect to see this more on a client PC than a server but if you are trying everything out on say a windows box then that also needs its own HOME.
Have fun.

Reports Requirements using R12 and Oracle 10g Reports

Hi All,
Looking forward to some valuable inputs to propose a technical solution in R12 using 10g Reports Developer.
Requirements are :
1. Report output should be in Excel Format. ( Is this possible without XML Publisher using 10g Reports only )
2. Report Parameters to have multi selection criteria. ( Is this possible in 10g Reports and Oracle Apps, Report Manager responsibility ?)
Regards,
Anand

>

Crystal Report and Oracle SDO_GEOMETRY

I tried the same with the Crystal Reports 2008 trial version and i'm having the same problem.
 
 
I don't wanna use the geometry column in my report but because of this error i can't use the whole table. Is there a way to avoid this error and still use the other columns of the table. Or maybe there is another way to connect to an Oracle database which can handle this special data type.
 
 
Thanks in advance,
 
 
Jens Keller

Hi Jens,
Views would work also as you noted.
No, if DB manufacturers change/update their Servers/clients they need to follow ANSII 92 standards. If they don't return the correct data type then CR will not "hack" our drivers to fix their issues. We did that for years and was a code nightmare, when they got around to fixing the problem it broke CR again. We decided to follow the standards, it may be our issue sometimes but in this case unique data types typically are not supported by CR. If you want support and it's not a client issue then add your request to the Enhancement Request2 post.
So yes in your case it would make it easier but for others they'll be asking why CR doesn't show all fields. Same reason.... not a CR issue.
Thanks agian

Database connection encryption and integrity with ColdFusion and Oracle thin client

As ColdFusion datasource we are using the Oracle thin client to connect with the database. So, basically we are using a JDBC URL such as jdbc:oracle:thin:@... and as Driver Class oracle.jdbc.OracleDriver. This works successfully however we would like to set encryption and integrity parameters as well. In Java this is done similarly by setting a Properties object prior to getting a connection as follows:
Properties prop = new Properties();
prop.put("oracle.net.encryption_client", "REQUIRED");
prop.put("oracle.net.encryption_types_client", "( DES40 )");
prop.put("oracle.net.crypto_checksum_client", "REQUESTED");
prop.put("oracle.net.crypto_checksum_types_client", "( MD5 )");
OracleDataSource ods = new OracleDataSource();
ods.setProperties(prop);
ods.setURL("jdbc:oracle:thin:@localhost:1521:main");
Connection conn = ods.getConnection();
Is there a way that I can pass these parameters to the ColdFusion datasource. Ideally, I would love to do this centrally in such way that a change to all the cfquery or cfstoredproc is not needed.
I also know that in application servers such as Oracle AS there is an option when creating a datasource which says "Add Properties". In there you can add such properties. So, I was thinking of maybe creating a JNDI DS in the app. server and then magically connecting to it but this may have some impacts on the app.
Besides this I was also thinking of communicating with the CF datasource through the CF admin API (cfide.adminapi.administrator) and also the option of extending the Oracle driver so that when CF connects with it these params are already set.
I would love to have your professional opinion and suggestions on this.

I believe the thin driver actually needs the IP address (not the DNS name). Also, is "java" the name of the Oracle instance to which you are trying to connect?
Try the following:String driver = "jdbc:oracle:thin";
String dbIP = "W2RZ1NXG01's IP address";
String dbPort = "1530";
String dbSid = "java";
String dbUser = "Admin";
String dbPswd = "apassword";
String cnctStr = driver + ":@" + dbIP + ":" + port + ":" + dbSid;
try
    Class.forName("oracle.jdbc.driver.OracleDriver");
    con = DriverManager.getConnection( cnctStr, dbUser, dbPswd );
    stmt = con.createStatement();
    stmt.executeUpdate(createString);
    stmt.close();
    con.close();
catch(SQLException ex)
    System.err.println( "The following SQLException occurred: " + ex );
    System.err.println( "Message: " + ex.getMessage() );
