Oracle distributed query problem

Hi,
I am running a nested query on multiple oracle servers of 10g R2 using DBLinks. But if the levels of nested query is increased e.g 3 or 4, oracle gives an error of ORA-02063.
Can any one please help on this.
Thanks,
Usman

Thanks for the quick response.
Following is the query:
select
Count( nvl(t1_st.t1_st_DG1.EMPTY,0)) AS "F1" ,
Count( nvl(rpt2."F2",0)) AS "F2" ,
Count( nvl(rpt1."F3",0)) AS "F3"

ORA-02063: preceding line from DBL_4_15_2008_4_41_11_PM761
Please note that query itself has no errors (i have confirmed this by running the query on its own server i.e without dblinks)

Distributed Query Overhead

Hi All,
I have a distributed deployment of two oracle instances where database A keeps a replication of a schema from database B.
I have A and B linked together, B sees A as a remote database, and my application sends queries to database B.
Let's say I have the following two queries:
The following is issued to B:
select * from magic.accountejb@A a where a.profile_userid = ( select userid from magic.accountprofileejb@A ap where ap.userid = 'uid:174')
and the following issued directly to A (which is basically the same query as above):
select * from accountejb a where a.profile_userid = ( select userid from accountprofileejb ap where ap.userid = 'uid:174')
when I measure the time through my Java application, the second query executes more than 3 times faster than the first query (23ms on A compared to 80ms on B). However, when I use the sqlplus client on B to issue the exact same query, the execution time reported by sqlplus is almost identical to the second one(20ms).
When I monitor the execution plan through *@UTLXPLAN*, it seems like the query sent to B is also fully executed remotely and on A. with a network latency of 11ms between A and B, I am not sure why I see such a long delay for the first query. Also playing with DRIVING_SITE did not have any perceived effect on improving performance.
I wonder if anybody has any explanation for the difference I see? is a distributed query really 3 times slower than a regular query even though both are pretty much handled by the same database engine? or is it so that I need some other sort of tuning?
Any thoughts or advice on how I can achieve comparable performance is highly appreciated.
thanks!

5. for performance related issues - the data volume being queried or processedThe data volume is rather small. I measure the data and it is roughly about 10K of data transfer.

Without seeing the code to see how you are measuring the timing it is hard to comment on what you posted.
3. How was the timing computed in sql*plus?for sqlplus, I issue *set timing on* prior to executing the queries.
4. Were the connections already created before the timing started? Or is the creation of the connection part of the timing result?As you see in the code, the connection is only created the first time I issue a query, and I discard the results of the first two queries using the connection as the timing is far off specially for the first query. I think the first query also download some metadata information that I don't consider in calculating the performance.
5. Do the timings include the retrieval of ALL result set data? Or just the first set of results?the time only consists of executing the first set.
Can you post the explain plans for the java and the sql*plus executions?Here is the results of the explain plan

Avoid Distributed query in PL/SQL cursor code

Hi,
I have to avoid a distributed qry in my cursor code in PL/SQL.
The query follows like this,
cursor c1
is
select a.test,b.test1,a.test2
from apple a,
[email protected] b,
bat c
where a.listid = b.listid
and a.list_name = c.list_name;
Now i need to split the above cursor into two .
(1)I need to query appl and bat which is from local database into one and
(2)Have to do something for the value from [email protected] is stored in a temp. table or PL/SQL table.So that ,i can use the PL/SQL table or temp table in my join in cursor ,instead of having a distributed query.
By doing so,will the performance hit badly ?
[Note: Imagine this scenario is taking place in Oracle 11i Apps]

Converting Oracle XML Query Result in Java String by using XSU

Hi,
I have a problem by converting Oracle XML Query Result in Java
String by using XSU. I use XSU for Java.
For example:
String datum=new OracleXMLQuery(conn,"Select max(ps.datum) from
preise ps where match='"+args[0]+"'");
String datum1=datum;
I become the following error:
Prototyp.java:47: Incompatible type for declaration. Can't
convert oracle.xml.sql.query.OracleXMLQuery to java.lang.String.
Can somebody tell me a method() for converting to solve my
problem??????
Thanks

Hmmm.. Pretty basic just look at the example:
OracleXMLQuery qry = new OracleXMLQuery(conn,"Select max(ps.datum) from preise ps where match='"+args[0]+"'");
String xmlString = qry.getXMLString();

Oracle text query

Hi,
I have a View object with various attributes (eg, name1, name2, name3, address1, address2, address3 etc). A query/table component based on this view object works just fine. However, I wish to replace name1, name2, name3 and other attributes in the query with just 'name'. These attributes are still to be shown in the result table. This new 'name' attribute will be used in an Oracle Text query clause, instead of individual searches on each attribute.
My plan was to simply make the various name1, name2 etc attributes non-'queryable' in the View def to hide them from the query. Then I'd add a transient 'name' attribute. My hope was, that I could override the getWhereClause() in the ViewObjectImpl and simply tack on the oracle text clause to the WHERE (example below):
WHERE CONTAINS (
SOMECOLUMN,
            '<query>
   <textquery lang="ENGLISH" grammar="CONTEXT">TRANSIENT_ATTR_VALUE
..... Oracle Text query grammar stuff here .... </query>') > 0How do I access the transient value in the ViewObjectImpl to add the above SQL? Or am I going about this in completely the wrong way?
thanks,
Barry.

Oracle distributed doc capture - commiting

hi i'm currently researching on oracle doc capture and oracle distributed doc capture products,
currentyly i've problem in the commiting feature from the web oddc client,
after i scanned documents, i click send, (im using text commit profile)
but when i check in the commit folder at the capture server, there's nohting in it
(i've use c:\odc\commit for the commit folder)
but there's something in the IIS webcapture clientaccess folder (C:\Program Files\Oracle\Document Capture\WebPages\ClientAccess)
its a .PAK file name, when i open it in winrar, its indeed the document that i scanned and send from the client.
but why is it stored in here? what's with the .PAK format, and how to configure the settings properly for storing
files with its proper format (TIFF, JPG, PDF) in the server ??
i'm using recent odc and oddc from oracle, in windows 2003.
any help will be appreciated, if this works, i'll try commiting to ucm (so far it isnt working also)

thank you ram for your response,
yes you're right i actually didnt notice there are ODDC service in in windows service list,
when i started it (not automatically started when installed) the package get "commited".
ok, now that the service is up, there are new problems here,
i want to integrate ODDC with UCM, ie: commiting to UCM,
when i commit to UCM, and check ODDC log, it seems that it results in an error, like this ...

Distributed Query in-parallel?

I tried to execute distributed query on three database machines. I hope it would be executed in-parallel. Unfortunately, I found I used 3 times of execution time with distirbuted query compare to search in only one node. Obviously, the query statement was processed one by one. (Data was distributed in three nodes averagely)
Here is the example.
select * from nemo.seven_dis_table
union
select * from [email protected] where rownum<=1000
union
select * from [email protected] where rownum<=1000
With the docuemnt http://www.dba-oracle.com/t_opq_parallel_query.htm, this sql would be executed on two remote site in-parallel. My question is, why can not be executed in-parallel in my case? Is it really parallelism query?

I'm by no means an expert in distributed queries, but having read through the document you linked and looking at your query, I think you're misunderstanding either distributed processing or the union statement.
At the moment, all you're doing is getting data from three sources and then mashing it together with a costly union statement.
If you put in UNION ALL instead, it would give you a better idea of how fast it retrieves data because it won't bother sorting and removing duplicated records.
The idea behind distributed processing is that you can query a very large table on ONE database using multiple processors, not multiple databases on different servers....

Oracle 10g forms problem

hi
can any body help me?
i have installed oracle developer 10g with oracle 8i database
when i run any form including the test.fmx
it always ask to install JInitiator although it has been installed (appears in the control panel and in c:\program file\oracle folder)
another problem appears after completing the installtion of JInitiator
the browser views the HTML tags of the form not execute it
so does any body have any idea???

From the Windows Start menu, choose Run, type regedit, and click OK.
Expand the registry nodes HKEY_LOCAL_MACHINE > SOFTWARE > ORACLE.
Make a backup copy of this key by right-clicking it and selecting Export from the context menu.
Select one of the HOME nodes beneath the ORACLE node (the one for Developer Suite). Ensure that you have opened the correct node by verifying that the key FORMS90_PATH exists in that node.
From the Registry Editor menu, select Edit > New > String Value. Type in the name FORMS90_HIDE_OBR_PARAMS.
Double-click FORMS90_HIDE_OBR_PARAMS and in the Value data field enter false, then click OK.
Close the registry editor.
Now when you run a form from Forms Builder, it should show parameters, including userid, in the URL, but it should run fine.
15. Set the path for Forms Builder to locate icons:
a) Double-click the UI_ICON key to open it for editing.
b) For the value data, append the path to the .gif file that you will use for the
button icon, which is the \icons subdirectory of your lab directory. Separate this
path from the remainder of the string with a semicolon; for example:
;e:\labs\lab\icons, then click OK.

i have made one oracle 6i reports. its is quite wide.when i run the report it shrink into too small font.
and i increse it font size it by pressing + button on menu bar it looks okay.
>
The + button only causes a zoom in on the screen. It is not affecting the actual layout.

but the problem is that when i take print out of it ,it's printout comes in its intial format(in small font) evenif i choose different type of paper size or different orientation . it's printout is coming in too small font.
pl tell me how to overcome this problem>
The report rendering engine tries to fit the report page into the physical page size. This results in shrinking of font size,etc.
To fix
a) reduce the content on the report to something reasonable for printing.(Std paper sizes and orientation)
b) change the page size selection. Of course, you will need a printer and paper of the size you set.

Oracle Text query: Escaping characters and specifying progression sequences

How can I combine the escaping of a search string and the specification of progression sequences within an oracle text query
so that in all cases the correct results are delivered (see example below)?
The scenario in which to use this is the following:
+ Database: Oracle Database 10g Enterprise Edition Release 10.2.0.2.0
+ Requirement: Hitlist of results ordered by score whereby the different part within
the result list are specified using progression sequences within oracle text query
Example:
create table service_provider (
id number,
name_c varchar(100),
uri_c varchar(255)
insert into service_provider values (1,'ABB Company Mgmt','http://www.abb-company-mgmt.de');
insert into service_provider values (2,'Dr. Abbas Ming','http://www.dr-abbas-ming.de');
insert into service_provider values (3,'SABBATA United','http://www.sabbata-united.de');
insert into service_provider values (4,'ABB','http://www.abb.de');
insert into service_provider values (5,'AND Company Mgmt','http://www.and-company-mgmt.de');
insert into service_provider values (6,'Dr. Andas Ming','http://www.dr-andas-ming.de');
insert into service_provider values (7,'SANDATA United','http://www.sandata-united.de');
insert into service_provider values (8,'AND','http://www.and.de');

Oracle distributed document capture OCR

there is no OCR in Oracle distributed document capture there is any solution fro this issue ??

Yes, the 11.1.1.8 version has Capture as a managed server and not as a windows based desktop app. So no seperate installer for the same.
Also, Looks like they'ave covered the ODDC use cases in the Capture itself, that being a web app now.
regards,
Pradeep Mahajan.

Oracle distributed document capture service not started

Oracle distributed document capture service not started
and timeout

I did check the Distributed Document Capture Configuration (from the Start menu) and it also indicates that I have selected "Oracle Distributed Document Capture Prompted Login". Once I click "OK" after I supplied all the paths required by server settings, it also displays the error "The username and password could not be validated". What credentials should be entered in the User ID / Password / Domain fields? You should use the username and password entered while configuring the "capture" security model. Leave the domain field blank.
I have not yet configured the IIS at this point. Is it required for the Capture application to authenticate the user I specified during the installation configuration at login? IIS will serve web ODDC interface and will be needed for authentication while accessing ODDC web pages. I beleive that it is not needed for authentication from ODC/ODDC applets. However, when something is not working as expected, I would first finish all required installation and especially post installation setup steps.
I had a look at the IIS configuration in the installation document. It doesn't clearly state which document is the default document for the website one needs to create in IIS. Do you know what it should be? You have to add new web site, say like "Capture" and add virtual directory from assumed path like: C:\Program Files\Oracle\Document Capture\WebPages
For the default document I have WebCapture.asp.
The Oracle Distributed Document Capture service does no start on my PC. Is this required for me to atleast login to the Capture application? It's required only for processing the scanned batches.
I hope that this will help.

Designing LOV Query Problem

Hello APEX people,
I posted my problem here:
Designing LOV Query Problem
What I have is a sequence like this:
CREATE SEQUENCE
DR_SEQ_FIRST_SCHEDULE_GROUP
MINVALUE 1 MAXVALUE 7 INCREMENT BY 1 START WITH 1
CACHE 6 ORDER CYCLE ;
What I need would be a SQL query returning all possible values oft my sequence like:
1
2
3
4
5
6
7
I want to use it as a source for a LOV...
The reason why I use the cycling sequence is: My app uses it to cycle scheduling priorities every month to groups identified by this number (1-7).
In the Admin Form, I want to restrict the assignment in a user friendly way - a LOV.
Thanks
Johann

Here ist the solution (posted by michales in the PL/SQL forum):
SQL> CREATE SEQUENCE
dr_seq_first_schedule_group
MINVALUE 1 MAXVALUE 7 INCREMENT BY 1 START WITH 1
CACHE 6 ORDER CYCLE
Sequence created.
SQL> SELECT LEVEL sn
FROM DUAL
CONNECT BY LEVEL <= (SELECT max_value
FROM user_sequences
WHERE sequence_name = 'DR_SEQ_FIRST_SCHEDULE_GROUP')
SN
1
2
3
4
5
6
7
7 rows selected.
