Nvarchar2 in oracle 8i and 9i

Hi All,
I am woking in 9i d/b and changed a column from varchar2(50) to nvarchar2(50) from 9i client. Now I am connecting to the 9i d/b from a 8i client and when i am doing desc of the table then the column is showing nvarchar2(150) but when I'm doing desc of the table from 9i client then it shows nvarchar2(50). What is the reason behind this behhaviour of 8i, is this due to the increase in byte when data type is nvarchar2?
Thanks & Regards,
Sudipta

What is your national character set? What is NLS_LENGTH_SEMANTICS set to?

Tomcat, Oracle 9i and Chinese Characters

Dear Group,
we are using an application based on oracle 9i and tomcat 5.0. I copied the "ojdbc14.jar" and "nls_charset12.jar" to my common/lib directory of Tomcat.
The application works fine until I insert chinese characters via the web form from our app. If I insert the chinese characters directly with the oracle enterprise console, it works.
NLS_NCHAR_CHARACTERSET is AL16UTF16
Any idea?
Thanks in advance
Ray

Are you inserting the Chinese characters into a VARCHAR2 column or into an NVARCHAR2 column?
What is your NLS_CHARACTERSET?

Oracle, Null and empty Strings

Currently I'm facing problems with a class, which contains a String, which
is set to "" (empty String).
When the class is persistent, oracle writes null to the table column
(which seems to be common oracle behaviour) and when retrieving the class,
the field is set to null as well, giving me a lot of null-pointer
exceptions.
Anyway ... I can cope with that (just a lot of extra work)
far worse is the problem, wenn searching objects, that have this field set
to "" oder null.
Oracle can't find the records because JDO creates Querys "where
string=null" or "where string=''" , where oracle expects "where string is
null" to find the records.
Is there a workaround or solution ?

Yeah, that would work as well, thx, but since I have to cope with
null-Strings now everywhere in my program, it doesn't hurt just to forbid
empty strings on the program side.
In future times I'll test on Oracle first, then porting to DB/2 - this way
I suppose work is far less to garant compability.
Nevertheless ... having to set the bankcode into quotes is a kodo bug in
my opinion.
Kodo knows the type of classfields (in this case string) and shouldn't
send the parameter as a BigDecimal to the database.
Given that, and having only bankcodes of null (only neccesary when using
Oracle), the method would look like:
public Collection getAccounts (String bankCode)
throws Exception
return getAccounts (Account.class, "bankcode=="+bankcode);
which is how a transparent persistent layer, um, should be , um , I mean
... just transparent ;-D

Couldn't you just do something like:
public Collection getAccounts (String bankCode)
throws Exception
String filter;
if (bankCode == null || bankCode.length () == 0)
filter = "(bankCode == null || bankCode == "")";
else
filter = "bankCode == "" + bankCode + """;
return getAccounts (Account.class, filter);
If I understand the problem correctly, this should work for all the
databases.

What operations are you performing to cause this SQL to be issued? You
say you are having trouble removing objects, but this is clearly not a
DELETE statement. Is this the SQL that is issued when looking up
objects by identity?I'm not removing objects, I was removing just quotes from parameters ;-)
A string column... is it also represented as a string field in your class?Yeah ... just to give you an impression of the code:
First we have a class, representing a bank account:
public class Account {
private AccountMgr myAccountMgr;
private String bankCode;
private String id;
Note, that in nearly all cases bankCode will be a number or null.
I have a second class "AccountMgr", which does all of the persistant stuff
(seaching, making persistent etc.)
This class has two methods, one versatile (protected) to retrieve accounts
by a given filterString and one who just returns accounts by bankCode,
building the expected filterstring. Here is my current working version:
public class AccountMgr {
public Collection getAccounts(String bankCode) throws Exception {
if (bankCode!=null) {
if (bankCode.equals("")) {
throw new Exception("check code, bankCode='' not allowed to get
same behavior from DB2 and Oracle");
// if set, quote the bankCode
bankCode="""+bankCode+""";
return getAccounts(Account.class,"bankCode=="+bankCode);
protected Collection getAccounts(Class accountClass, String filterAdd)
throws Exception {
PersistenceManager pm = MyHelper.getPersistenceManager();
String filter="";
if (filterAdd!=null && !filterAdd.trim().equals("")) {
filter+=filterAdd + " && ";
filter += "myAccountMgr==_accMgr";
Query query = pm.newQuery(accountClass, filter);
query.declareParameters("AccountMgr _accMgr");
return (Collection) query.execute(this);
As you can see, in the first method I have to set the bankCode into
quotes, when it's not null.
This is because otherwise a filter like "bankCode=1234" will be translated
in a way, where 1234 is send as a BigDecimal to the database:
[...] executing statement <4239745>: (SELECT [...] FROM JDO_ACCOUNT t0
WHERE t0.BANKCODE = ? : [reused=1;params={(BigDecimal) 1234}]

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 ->

What is the Diffrence between Oracle 11 and 11i

What is the Diffrence between Oracle 11 and Oracle11i ?.
With Rgds
Arun J.Isaac

Oracle 11i is internet based and run with java platform where we can see the applets downloading alongwith oracle forms and it refreshes all the jar files in oracle default directory.
Oracle 11 is not intergrated with Java its an Oracle standalone platform.

hi user ...
on windows there are some steps in front of installation and configuration.
1) cleare the Windows Env (Path .. Programme x86 )
no Blank in Path and so on
2) insert into your local host file your server and IP Adress
3) in Windows 32 setup of WLS is JDK included so you don't have to install the jdk in front of WLS
4) verify if you are using the right installation medium (jdk 32 bit, wls 32 bit , fmw 32 bit
in your OraInventory/logs directory is a *.out file for your installation please can you put this file in the forum
is there a nodemanager up and running (if so please stop)

We're trying to integrate Discoverer with Portal unsuccessfully.
We made many things in accordance with oracle's documentation until add discoverer portlets (worksheet and list of workbooks) in a test page.
In view mode, the worksheet portlet shows the error:
"The portlet has not been defined. The publisher must define the portlet by clicking on Edit Defaults for the portlet on the edit mode of this page. Please contact the publisher of this page."
We think we have to edit properties before. Is this? Anyway edit worksheet portlet crashes between step 1 and 2. The error is: "The listener returned the following Message: 500 Internal Server Error".
We have a public conection created in EM and a discoverer application which can be viewed using plus or viewer.
Furthermore, it's not possible delete the added portlets neither the page that contain it. The error at delete is:

Hi there,
Have you applied any patches to 9ias since it was first installed? We had the same problem and had to apply a couple of patches to get the portlets working.
1. Apply the 9.0.2.53.16 one-off patch for Oracle 9iAS Discoverer which takes Discoverer up to 9.0.2.53.16. This patch appears to be password protected and you need to get someone at Oracle support to give you a password.
2. Apply the Discoverer Portlet Provider: 9.0.2.53.00c patch (patch no. 2595444) which gives you a new discportal.xsl file that actually works. It's this second step that solves your problem but you need to do step 1 before this. This is password protected as well.
3. As you've upgraded Disco on the server to 9.0.2.53, you'll need to upgrade Disco Admin & Desktop within your 9iDS installation using patch no. 2555265. This is because Disco 9.0.2.53 uses an upgraded EUL that Disco Admin & Desktop need to be patched to use.
This was the course of action Oracle support advised us about nine months ago. Of course they may have released a further patch to Disco that does 1 & 2 in one go, but we regularly carry out steps 1 and 2 on servers we use and we can use the Disco portlets successfully.
Hope this helps

Oracle optimizer and heterogeneous services (Transparent Gateway for ODBC)

Hi everyone!
We have the following configuration:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production.
Oracle Database Gateway for ODBC 11.2.0.2.0 on the same machine as Oracle DB.
Non-Oracle DB installed on a different hardware accessed through Oracle Gateway for ODBC via dblink.
Now, we have to query the remote non-Oracle system and retrieve some data. For the sake of brevity let's suppose we have the following table in our non-Oracle DB:
create table test (
     ip_address varchar(15),
     start_time datetime,
     end_time datetime
And we run the following SQL query against the remote table on our Oracle DB:
SELECT start_time,end_time,ip_address
FROM remote_table@db_link
WHERE
end_time >= to_date('2011-10-11 00:00:00','rrrr-mm-dd hh24:mi:ss')
OR (
end_time IS NULL AND start_time >= to_date('2011-10-11 00:00:00','rrrr-mm-dd hh24:mi:ss')
AND start_time <= to_date('2011-10-12 00:00:00','rrrr-mm-dd hh24:mi:ss')
AND ip_address = '127.0.0.1';
But, having query monitoring on the remote DB enabled, we see that the actual query on the remote site looks like this:
SELECT "START_TIME","END_TIME","IP_ADDRESS"
FROM "REMOTE_TABLE"
WHERE "IP_ADDRESS"='127.0.0.1' AND "START_TIME"<=?
All references to END_TIME column are gone from WHERE clause for whatever reason.
However, Oracle execution plan shows us the following:
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Inst |IN-OUT|
| 0 | SELECT STATEMENT | | 1 | 27 | 200 (0)| 00:00:03 | | |
|* 1 | FILTER | | 1 | 27 | 200 (0)| 00:00:03 | | |
| 2 | REMOTE | REMOTE_TABLE | | | | | DB_LINK | R->S |
Predicate Information (identified by operation id):
1 - filter("END_TIME">=TO_DATE('2011-10-11 00:00:00','rrrr-mm-dd hh24:mi:ss') OR
"END_TIME" IS NULL AND "START_TIME">=TO_DATE('2011-10-11 00:00:00','rrrr-mm-dd hh24:mi:ss'))
Remote SQL Information (identified by operation id):
2 - SELECT "END_TIME","IP_ADDRESS","START_TIME" FROM "REMOTE_TABLE" WHERE
"IP_ADDRESS"='127.0.0.1' AND "START_TIME"<=:1 (accessing 'DB_LINK' )
This actually means that Oracle CBO decided that it will apply filter on END_TIME column after having retrieved the data from the remote site. We don't want this behaviour but have no idea how to affect execution plan in this case.
So, the question is: How can we force Oracle CBO to not change the initial query and pass it to the remote site "as is"? Is there any way we can achieve this goal?

Hi,
Our Oracle DB and Gateway are running on the following system:
HP-UX B.11.31 U ia64
The following SQL code is executed in SQLPlus:
SELECT start_time,end_time,ip_address
FROM ip_acc_complete@gr_link
WHERE
END_TIME >= to_date('2010-10-21 00:00:00','rrrr-mm-dd hh24:mi:ss')
OR (
END_TIME is null AND START_TIME >= to_date('2010-10-21 00:00:00','rrrr-mm-dd hh24:mi:ss')
AND START_TIME <= to_date('2010-10-22 00:00:00','rrrr-mm-dd hh24:mi:ss')
AND IP_ADDRESS = '127.0.0.1';

The non-Oracle DB is CopperEye Retrieval Server with its own custom ODBC driver.
CopperEye query log shows that the following query is received from Oracle Gateway:

SELECT "END_TIME","IP_ADDRESS","START_TIME" FROM "IP_ACC_COMPLETE" WHERE "IP_ADDRESS"='127.0.0.1' AND "START_TIME"<=?
which complies with the information in Oracle Gateway trace file.
So, it seems that it's Oracle DB decision to split the original WHERE clause into two parts, delegate one part to the remote site, retrieve the data and then apply the remaining filter locally.

Oracle XE and character set

Hello all,
I installed Oracle XE on RHEL 4 Linux and I found out that database character set is AL32UTF8. Does anyone know why oracle choose this character set? Maybe because of NLS_LANG env variable? Is it possible to change it to EE8ISO8859P2? Since database is still empty I can drop it and crate new database.
Do you think it is possible to set some env variables and do new oracle xe instalation including database with iso charset?
I want to have EE8ISO8859P2 charset because of doing exp/imp from another oracle iso db to oracle xe and it is much easier to do this without charset conversion.
Any help will be appreciated.
regards,
Miha

When you download XE, you have a choice - take the 'western european' character set download, or the 'unicode' download.
No other choices.
Join us over in the XE forum where people have discussed this and found workarounds. Info about finding that forum at Re: Oracle XE Installation failed

Oracle Thin and IE4

Hi,
I have written an applet using Oracle Thin (classes111.zip and Oracle 7.3.4 and JDK 1.1.4).
I have my Oracle Server and my Web Server on the same machine.
Everything works fine with Netscape 4.7.
But with IE4 I have this message:
java.sql.SQLException: No suitable driver
java.lang.NullPointerException
Can anyone explain me what it means and what I have to do ?
Thanks a lot.

Can you try registering the driver explicitly using DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()). I think that there was some issue with Microsoft's VM that doing Class.forName() doesn't register the driver automatically. But I am not 100% sure.

Oracle Arrays and getVendorConnection API and Class Cast Exception

I 've gone through various threads relating to the topic of Oracle Arrays and the getVendorConnecton API call to avoid the class Cast Exception.. i ve used all these but am still facing the problem...
I would appreciate it if some one could resolve the following queries :
I am using Weblogic 8.1 SP5 with oracle 8i
1. I read that the need to use the getVendorConnection API to make pl/sql proc calls with oracle arrays from the WL Server wont be required to avoid classCastException...
I tried to use the connection from the WL connection pool ..but it didnot work....I used the getVendorConnection API ..which also doesnot seem to work..
I got the Heurisitc Hazard exception...I used the Oracle 9i driver ie ojdbc14.jar ...after this the exception is not coming but still the code doesnt seem to work...
the snippet of the code is pasted below :
~~~~~~~~~~~~~~~~~~~~~~~code is : ~~~~~~~~~~~~~~~~~~~
/*below :
logicalCon is the Connection from the WL connection pool
JDBCcon is the JDBC connection. */
<div> try </div>
<div>{ </div>

</div>{</div>
<div>System.out.println(" I ve come to finally"); </div>
<div>}</div>
<div>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~code snippet ends here ~~~~~~~~~~~~~~``
</div>
I have observed that the control immediately comes to the finally block after the call to the createDescriptor line above with <u>^%^%^%</u> in the comment. If i use the JDBCCon in this line...it works perfectly fine.
Any pointers to where anything is getting wrong.
I have jst set the vendorCon to null in the end of the file and not closed it. Subsequently i have closed the logicalCon. This has been mentioned in some of the thread in this forum also.
Thanks,

Oracle 8 and 8i ODBC drivers

I have written a win32 client application with Visual C++ for accessing an oracle 8.0.5 server on a linux platform.I have used an ODBC connection (MFC classes CDatabase e CRecordset). In application I have used a recordset on a view for updating the view's base table. On a view I have defined an instead of update trigger. All works fine. Now I must migrating it on an oracle 8.1.7 oracle server (or on win2k or linux). End now start the problem. On 8i server, after executing the query on the view, the function SQLGetStmtOption with SQL_CONCURRENCY param return SQL_CONCUR_READ_ONLY, making the recordset read only and i don't modify the view. What's the differences between Oracle 8 and Oracle 8i ODBC driver? Why with Oracle 8i I don't modify a view?
null

Executed query is
SELECT * FROM VIEW_NAME WHERE ID = value
where ID is a primary key of the only key preserving table of the view.

Oracle 8i and Images

Hi
I am using Oracle 8i and Oas 4.0.7. I wanted to load gif/jpeg files into Oracle Database and then I wanted to display it in the HTML page ? Is it possible to do like this in Orcale ? If anybody tried this, please advice me
null

Hi,
This may reach you late. but if you havent yet solved your problem...
Oracle provides a utility called Oracle Intermedia which is downloadable from the Oracle site.
This utility can be used with Oracle 8i and comes with a clipboard utility. You will be able to store and retrieve images, audio and video from the database using this.
Ciao,

Oracle ifs and BEA weblogic

Oracle ifs and BEA weblogic
We have one application server with weblogic and and ifs 1.0.9 , and one db server with Oracle 8.1.7.
with the following configuration:
Web server
appl server with weblogic 6.0 and ifs 1.1.9
Oracle 8i Enterprise with interMedia text
We need to use the iFS API call for our application.
As I know, weblogic 6.0 support JDK1.3 but ifs 1.1.9 supports up to JDK1.2.
Is this configuration possible?
Any conflict if two version JDK co-exist inside same machine?
Any suggestion?
If I separate the appl. server into two machines, that is,
one server installed with weblogic, the other one installed with ifs.
How could I make use the ifs API call from appl. server?
Is there any configuration guides for this setting?
Thanks a lot.

<BLOCKQUOTE><font size="1" face="Verdana, Arial, Helvetica">quote:</font><HR>Originally posted by Luis:
The iFS API is 100% pure Java. You can use it from any other Java application, be it JSP, EJB, or a standalone application.
So it really comes down to the CLASSPATH. The iFS API is split among a set of .jar files, and some of the configuration information is stored in .properties files that are outside of these .jar files. All of this stuff needs to be in the CLASSPATH of whatever JVM is calling the iFS API.
The iFS API uses the Oracle JDBC driver to communicate with the Oracle database. This is another requirement. You can't use another JDBC driver; you have to use ours.
So again, it's all about configuration.<HR></BLOCKQUOTE>
Would you mind to share more detail on configurating weblogic to integrate the iFS API?

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,

Hello Priya,
Look into the following.
1. Book - Pro Oracle Spatial for Oracle Database 11g by r. Kothuri, A. Godfrind, E. Beinat. This book provides a nice introduction on Oracle Spatial concepts and have examples.
2. Look at the Oracle Spatial & Graph User Guide
2. Book - Applying and Extending Oracle Spatial by S. Greener and S. Ravada. This book provides hands on information for advanced oracle spatial application developers. Practical guide on hands-on examples, Data models and develop cross-vendor database solutions.
3. This oracle spatial forum, once you understand these concepts.
In the future consider Certification on Oracle Spatial 11g Certified Implementation Specialist.
