Problem with "locked records" on Oracle with UTF8

Hello,
Can somebody help me with "record is locked by another user" problem on Oracle 10.1.0.2 ?
Oracle is installed with UTF8 character set, and is running on Windows Server 2003. Whenever I try to edit numeric column I get the message "record is locked by another user". Selecting locks from v_$locked_object view, gets empty resultset - nothing is locked.
The problem occurs only when I edit numeric columns using client applications like TOAD or my own applications. When I do the same column update by sql query, everything works fine.
Is the problem connected with client configuration or maybe with UTF8 character set, or Windows Server2003?
We also have second Oracle 10.1 server on Linux, but with WIN1250 character set, and there's no problems like that.
Thanks in advance for any help,
remg

About the only thing you can do is automatically commit or rollback when the user presses the Enter Query key/button. In your key-entqry trigger, you would need to code this:
Clear_form(no_validate,full_rollback);
Enter_Query;

Lock records when in Update Mode / problem with 2 users on 1 document

Hi,
when user A updates e.g. a purchase order and user B goes into this purchase order and updates e.g. the remark before user A, then user A cannot save his changes. Imagine user A has put in several new lines and has made several price adjustments, his work will be gone.
In most cases this should not happen very often, but it could. Since B1 recognizes when another user has updated the document before, it should be possible to solve this situation more convenient (either by lock, saving to a new document, comparing to the old version, etc).
Thank you
Sebastian

Hi Sebastian,
Your request is understandable. It may not have big problem to change current process by coding. However to lock records whenever in update mode, that could create too many locks. It is basically not good for performance. The trade off may be allowing save as function. However, this may not be a desirable solution for most end users.
Thanks,
Gordon

Forms 6.0.5.0.2: Problems with Oracle 7.3.4, OK with 8.0.5

I have problems with Forms 6.0.5.0.2 running against an Oracle
7.3.4 with Net8. When trying to insert or update records I get
an FRM-40508: ORACLE error: unable to INSERT record/FRM-40509:
ORACLE error: unable to UPDATE record. The Help | Display Error
menu item shows statement = "S3AVWU3wo|$6o|" (garbled
message), error = "ORA-12663: Services required by client not
available on the server" (sometimes it's "ORA-01403: no data
found").
It works fine against 8.0.5. As far as I'm aware Forms 6 is
certified against 7.3.4?
Any clues?
Thanks for your help.

We had to upgrade from 7.3.2 to 7.3.4 when we moved over to Forms
6.0.5.0.2 and it's working fine.
We are using Net 8 as well.

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 RollBack in Oracle Batching

Hi all,
This is Adhil. I am facing a problem with Oracle Batching in java.
I am using java 1.5 and Oracle 10 g.
I have a below standalone code to test the Oracle Batching (Assume that i have the 2 tables with zero records ).
with the batch size set as 10, I am trying add 2 records in each table.
Now I rise divideByZero error exception manually and trying to rollback the connection in catch statement . But couldn't rollback the connection. I see the 2 records added in both of my tables.
The same code when i set the batchsize 2 and trying to insert 10 records ,I could rollback and no rows get inserted.
Since I am going to get the no of insert from user in runtime , my rollback may fail in any combinations as in my first case(with batch size 10 and if the no of insert is 2).

Mapping problem with compressed key update record

Hi, could you please advise?
I'm getting the following problem:
About a week ago replicat abened with "Error in mapping" error. I found in discard file some record looking like:
filed1 = NULL
field2 =
field3 =
field4 =
field5 =
datefield = -04-09 00:00:00
field6 =
field8 =
field9 = NULL
field10 =
Where filed9 = @GETENV("GGHEADER", "COMMITTIMESTAM"), field10 = = @GETENV("GGHEADER", "COMMITTIMESTAM"), others are table fields mapped by USEDEFAULTS
So I got Mapping problem with compressed key update record at 2012-06-01 15:44
I guess I need to mention that extract failed in 5 minuts before it with: VAM function VAMRead returned unexpected result: error 600 - VAM Client Report <[CFileInfo::Read] Timeout expired after 10 retries with 1000 ms delay, waiting to read transaction log or backup files. To increase the number of retries, use SETENV (GGS_CacheRetryCount = n) in Extract parameter file. To control retry delay time, use SETENV (GGS_CacheRetryDelay = n). handle: 0000000000000398 ReadFile GetLastError:997 Wait GetLastError:997>.
I don't know if it has ther same source as data corruption, could you tell me if it is?
Well, I created new extract, starting 2012-06-01 15:30 to check if there was something with extract at the time, but got the same error.
If I run extract beging at 15:52 it starts and works.
But well, I got another one today. Data didn't look that bad, but yet one column came with null value:( And I'm using it as a key column, so I got Mapping problem with compressed key update record again:(
I'm replicating from SQL Server 2008 to Oracle 11g.
I'm actually using NOCOMPRESSUPDATES in Extract.
CDC is enabled for all tables replicated. The only thing is that it is enabled not by ADD TRANDATA command, but by SQL Server sys.sp_cdc_enable_table, does it matter?
Could you please advise why does it happen?

Well, the problem begins somewhere in extract or before extract, may be in transaction log, I don't know:(

Regards,

The SCRP_CODE column has a NOT NULL constraint. The ORA-01407 error is telling you that you cannot update or set a value for this column to null because of the constraint. This has absolutely nothing to do with an index. You can use a marker/sentinel value in lieu of using NULL. For a numeric field, where everything is positive, a negative value (-1) can be decoded as meaning null. For a character field, a code such as NA can represent NULL.
This also has nothing to do (directly) with GoldenGate failing because of this error. The underlying SQL statement will fail everywhere, regardless of the tool or application. It is not a case of failing only in GoldenGate.

Problem with a primary key when creating a new record in Forms

My table has a field - MDD_KEY - that is a primary key. It is updated from a sequence with a before-insert database trigger. I know this works properly as the primary key was accurately populated when I inserted 1433 records.
In Forms 6, I have a form based on that table. I have set the mdd_key as a hidden field because I assume it will be entered by the before-insert trigger. However, when I enter data into the table, and then try to save it, I get a FRM-40202: Field must be entered. - followed by - FRM-40222: Disabled item MDD_KEY failed validation.
If I set DATA Required to no, when I try to save I get an FRM-40600: Record has already been inserted - but no such record exists in the database. I know this record is unique and does NOT exist because I deliberately made it up.
In the property palatte, the attributes of the field are:
DATA Data Type Number
Required Yes
DATABASE Database Item Yes
Primary Key Yes
Query Only No
Query Allowed Yes
Query Length 0
Insert Allowed Yes
Update Allowed Yes
Update Only if Null No
Lock Record No
I assume that my problem is that with a new record, the form wants to see the MDD_KEY populated before it saves - but that isn't going to happen until the before insert trigger fires in the database. I assume I have to populate that field within forms, but how do I do that without messing up the database trigger/sequence? I will have to load more data directly into the database - so I need the database trigger in place.
I have not used primary keys before so I am more than a little bit confused about how and when it should be populated when a new record is created in Forms.
Any help would be appreciated as I cannot enter new data into my form (works well with existing data).
Thanks

Problem with different resultset with same data and same query in Oracle 8.1.7 and 9i

Hello,
I have been using this query in oracle 8.1.7
SELECT
ID,
AREA_NO
FROM MANAGER_AREA MGR
WHERE COMPANY_ID = :id AND
(:value < (SELECT COUNT(ROWID)
FROM MANAGER_WORK MW
WHERE MW.AREA_ID = MGR.ID AND
(MW.END_WORK IS NULL OR MW.END_WORK >= SYSDATE)))
order by AREA_NO;
In the above query I want to see rows from MANAGER_AREA table depending upon date criteria in the table MANAGER_WORK and also upon the parameter :value i.e if I pass a value as 0 I get to see records for which their is atleast 1 record in MANAGER_WORK with the date criteria and if I pass -1 then I get all the records because minimum value that count(*) would give is 0. The resultset was as expected in 8.1.7.
A couple of days back I installed PERSONAL 9i to test for testing the basic functionality of our program with the same data. This query fails and irrespective whether I pass -1 or 0 it returns me same dataset which I would have got in case if I pass 0.
I do not know whether this is a bug that has got introduced in 9i. Can anybody help me with this problem. It would be difficult for me to change the parameter send to this query as the Query is called from many different places.
Thanks in advance

I cannot use a Group by and a having statement over here. The problem with 'Group by' and 'having' clause is If I have to make a join between the two tables. When I use join then I get only rows that are linked to each other in the table.
If I use outer join to solve that problem then I have to take in consideration the other date condition. My previous query use to virtually discard the corelated query result by using -1 as the value. This will not happen in the join query.

Problem with Oracle SQL Developer 3.0.04

1. Performing a "SELECT *" on an Oracle table with a SDO_GEOMETRY column locks up the tool and I have to use Task Manager to can it.
2. Clicking the Data tab on a table with an SDO_GEOM col either locks up the tool, or taked forever to return.
3. Performing a "SELECT" of a SDO_GEOM col either locks up the tool or takes forever to return.
None of these issues occur in Toad.

If you have a problem with SQL Developer, you'd be best off posting in the SQL Developer!

Please Help: A Problem With Oracle-Provided 'Working' Example

A Problem With Oracle-Provided 'Working' Example Using htp.formcheckbox
I followed the simple steps in the Oracle-provided example:
Doc ID: Note:116534.1
Subject: How to use checkbox in webdb for bulk update using webdb report
However, when I select a checkbox and click on the Update button, I get a "ORA-01036: illegal variable name/number" error. Please advise. This was a very promising feature.
Fred
Below are step-by-step instructions provided by Oracle to create this "working" example:
How to use a checkbox in WEBDB 2.2 report for bulk update.
PURPOSE
This article shows how checkbox can used placed on WEBDB report
and how to use it.
SCOPE & APPLICATION
The following example to guide through the steps to create a working
example of this.
In this example, the checkbox is used to select the records. On clicking
the update button, the pl/sql procedure is called which will update col1 to
the string 'OK'.
After the update is done, the PL/SQL procedure calls the report again.
Since the report only select records where col1 is null, the updated
records will not be displayed when the report is called again.
Step 1 - Create Table
From Sqlplus, log in as scott/tiger and execute the following:
drop table chkbox_example;
create table chkbox_example
(id varchar2(10) not null,
comments varchar2(20),
col1 varchar2(10));
Step 2 - Insert Test Data
From Sqlplus, still logged in as scott/tiger , execute the following:
declare
l_i number;
begin
for l_i in 1..50 loop
insert into chkbox_example values (l_i, 'Comments ' || l_i , NULL);
end loop;
commit;
end;
Step 3 -Create SQL Query based WEBDB report
Logon to a WEBDB site which has access to the database the above tables are created.
Create a SQL based Report.
Name the report :RPT_CHKBOX
The select statement for the report is :
select c.id, c.comments, c.col1,
htf.formcheckbox('p_qty',c.id) Tick
from SCOTT.chkbox_example c
where c.col1 is null
In Advanced PL/SQL, (REPORT, Before displaying the form), put the following code
htp.formOpen('scott.chkbox_process');
htp.formsubmit('p_request','Update');
htp.br;
htp.br;
Step 4 - Create a stored procedure in the database
Log on to the database as scott/tiger and execute the following to create the
procedure.
Note: Replace WEBDB to the appropriate webdb user for your installation.
In my database, I had installed webdb using WEBDB username, hence user webdb owns
the packages.
create or replace procedure chkbox_process
( p_request in varchar2 default null,
p_qty in wwv_utl_api_types.vc_arr ,
p_arg_names in wwv_utl_api_types.vc_arr ,
p_arg_values in wwv_utl_api_types.vc_arr
is
i number;
begin
for i in 1..p_qty.count loop
if p_qty(i) is not null then
begin
update chkbox_example
set col1 = 'OK'
where chkbox_example.id = p_qty(i);
end;
end if;
end loop;
commit;
/* To Call Report again after updating */
SCOTT.RPT_CHKBOX.show
(p_request=>'Run Report',
p_arg_names=>webdb.wwv_standard_util.string_to_table2(' '),
p_arg_values=>webdb.wwv_standard_util.string_to_table2(' '));
end;
Summary
There are essentially 2 main modules, The WEBDB report and the pl/sql procedure (chkbox_process)
A button is created via the advanced pl/sql coding which shows on top of the report. (The
button cannot be placed at the bottom of the report due to the way WEBDB creates the procedure
internally)
When any button is clicked on the report, it calls the pl/sql procedure chkbox_process.
The procedure is called , WEBDB always passes the parameters p_request,p_arg_names and o_arg_values.
p_qty is another parameter that we are passing additionally, This comes from the checkbox created
using the htf.formcheckbox in the report select statement.
The pl/sql procedure calls the report again after processing. This is done to
show how to call the report.
Restrictions:
-The Next and Prev buttons on the report will not work.
So it is important that the report can fit in 1 page only.
(This may mean that you will not select(not ticked) 'Paginate' under
'Display Option' in the WEBDB report. If you do this,
then in Step 4, remove p_arg_names and p_arg_values as input parameters
to the chkbox_process)

If your not so sure you can use the instanceof
insurance,
Object o = evt.getSource();
if (o instanceof Button) {
Button source = (Button) o;
I haven't thoroughly read the thread, but I use something like this:if (evt.getSource() == someObjRef) {
// do that voodoo
]I haven't looked into why you'd be creating a new reference...

Performance problem with Oracle

We are currently getting a system developed in Unix/Weblogic/Tomcat/Oracle environment. We have developed a screen that contains 5 or 6 different parameters to select from. We could select multiple parameters in each of these selections. The idea behind the subsequent screens is to attach information to already existing data/ possible future data that matches the selection criteria.
Based on these selections, existing data located within the system in a table is searched and those that match are selected. Also new rows are created in the table against combinations that do not currently have a match. Frequently multiple parameters are selected, and 2000 different combinations need to be searched in the table. Of these selections, only about 100 or 200 combinations will be available in existing data. So the system is having to insert 1800 rows. The user meanwhile waits for the system to come up with data based on their selections. The user is not willing to wait more than 30 seconds to get to the next screen. In the above mentioned scenario, the system takes more than an hour to insert the new records and bring the information up. We need suggestions to see if the performance can be improved this drastically. If not what are the alternatives? Thanks

The #1 cause for performance problems with Oracle is not using it correctly.
I find it hard to believe that with the small data volumes mentioned, that you can have perfornance problems.
You need to perform a sanity check. Are you using Oracle correctly? Do you know what bind variables are? Are you using indexes correctly? Are you using PL/SQL correctly? Is the instance setup correctly? What about storage, are you using SAME (RAID10) or something else? Etc.
Facts. Oracle peforms exceptionally well. Oracle exceptionally well.
Simple example from a benchmark I did on this exact same subject. App-tier developers not understanding and not using Oracle correctly. Incorrect usage of Oracle doing a 100,000 SQL statements. 24+ minutes elapsed time. Doing those exact same 100,000 SQL statement correctly (using bind variables) - 8 seconds elapsed time. (benchmark using Oracle 10.1.0.3 on a Sunfire V20z server)
But then you need to use Oracle correctly. Are you familiar with the Oracle Concepts Guide? Have you read the Oracle Application Developer Fundamentals Guide?

Problems with retrieving data from tables with 240 and more records

Hi,
I've been connecting to Oracle 11g Server (not sure exact version) using Oracle 10.1.0 Client and O10 Oracle 10g driver. Everything was ok.
I installed Oracle 11.2.0 Client and I started to have problems with retrieving data from tables.
First I used the same connection string, driver and so on (O10 Oracle 10g) then I tried ORA Oracle but with no luck. The result is like this:
I'm able to connect to database. I'm able to retrieve data but from small tables (e.g. with 110 records it works perfectly using both O10 and ORA drivers). When I try to retrieve data from tables with like 240 and more records retrieval simply hangs (nothing happens at all - no error, no timeout). Application seems to hang forever.
I'm using Powerbuilder to connect to Database (either PB10.5 using O10 driver or PB12 using ORA driver). I used DBTrace, so I see that query hangs on the first FETCH.
So for the retrievals that hang I have something like:
(3260008): BIND SELECT OUTPUT BUFFER (DataWindow):(DBI_SELBIND) (0.186 MS / 18978.709 MS)
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=1
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): EXECUTE:(DBI_DW_EXECUTE) (192.982 MS / 19171.691 MS)
(3260008): FETCH NEXT:(DBI_FETCHNEXT)
and this is the last line,
while for retrievals that end, I have FETCH producing time, data in buffer and moving to the next Fetch until all data is retrieved
On the side note, I have no problems with retrieving data either by SQL Developer or DbVisualizer.
Problems started when I installed 11.2.0 Client. Even if I want to use 10.0.1 Client, the same problem occurs. So I guess something from 11.2.0 overrides 10.0.1 settings.
I will appreciate any comments/hints/help.
Thank you very much.

Installing 11g client changed something that even using old 10g client (which I still have installed) fails to work. The same problem occur no matter I'm using 10g or 11g client now. Powerbuilder hangs on retrieving tables with more than like 240 records.
Thanks.

Problems with german umlauts when Migration from MS Access to Oracle

When I make a Migration from MS Access 97 to Oracle 8.1.5, I have Problem with the germans characters (umlauts). The Oracle is using the rigth character Set for german characters. What can I do? Is it e problem from the MS Access ODBC Driver or the Oracle ODBC Driver?

Is your character set for Oracle set up to UTF8??

Access vba problem with ORACLE database via ODBC

I get a problem when using MS-Access 2007 DAO recordset built on table hosted by an Oracle database 10g and connected thru an ODBC link (the id is generated by a sequence/trigger associated to the table).
The code I use is :
Private Sub Commande0_Click()
Dim rs As DAO.Recordset2
Dim bm As Variant
'Set rs = CurrentDb.OpenRecordset("select * from table1", dbOpenDynaset, dbSeeChanges, dbPessimistic)
Me.Recordset.AddNew
Me.Recordset!libelle = CStr(Rnd)
Me.Recordset!code = “”
Me.Recordset!actif = True
Me.Recordset!idCollege = 1
Me.Recordset.Update
Me.Recordset.MoveFirst
Me.Recordset.Bookmark = Me.Recordset.LastModified
Dim idtemp As Long
idtemp = Me.Recordset.idPartenaire
Me.Requery
Me.Recordset.FindFirst "idPartenaire = " & idtemp
Set rs = Nothing
End Sub
When I run this code, I get an error 3167 (current record is deleted) on the line :
idtemp = Me.Recordset.idPartenaire
If I change the ligne :
Me.Recordset!code = “”
By :
Me.Recordset!code = “xxxx”
Or if I comment this line, the error does not appear and I get the right value in idtemp variable.
I tried also with the same table in a SQL Server database table. In this case it works fine in all cases.
So, I seems that the problem is due to the Oracle ODBC driver.
I search on Internet but I have not found any explanation or solution.
Does anybody experiment the same problem (and find a solution)?
Gilles Roussel.

There is a dediacted forum for Oracle ODBC driver issues.
