Setting Transaction property in Oracle 11g

Hi All,
I am trying to learn the use of transaction property. I couldnt get the exact scenario by doing which i could get the need for that transaction property.
I have two tables in my DB.
Table1:_
Name,Location,Experience
Table2_
EmpID,CurrentDomain,CurrentSalary
Two bpels_
Bpel1 -> used to insert into Table1
Bpel2 -> To insert into Table2
If any one fails, then the other shd rollback.For this only , i would like to make use of that transaction property.
This is my requirement.
Bpel1:_
Gets the input from the client. which includes Name,Location,Experience,EmpID,CurrentDomain,CurrentSalary (ie., all the columns in table1 and table2)
I have an idea to invoke Bpel2 from Bpel1.
pls guide how shd i design the two bpels such tat i can see the importance of transaction property, so tat if insertion either in bpel1 or bpel2 fails then the other insertion shd also rollback..
I need this only by using transaction property and by some fault management. For now, i dont want to use compensate activity.
Please guide me in solving..
Thanks,
Sabarisri. N

Set events parameter in oracle 11g for SAP

Hi All,
Recently we have upgraded 10.2.0.4 oracle database to 11.2.0.3 (AIX 7.1) for SAP application.
Some non-default event parameters were set when Database was running with 10.2.0.4 version. After upgrade to 11.2.0.3, those events were not seen in pfile/spfile. However, post_upgrade log shows that those events were set (and log displays the list of the events as well).
Now, my concern is whether those event parameters were set already by default (if it is already set after upgrade, not sure why pfile not reflecting them) or do I need to set the parameters manually.
Thanks in advance for all your help.
Regards,
Prakash

Yes, they seem to be part of the upgrade itself, and SAP seems to set them in multiple places:
1) During the dbua.sap.sh run, post-processing calls custom scripts which set these events (check the CustomScript.log in $ORACLE_BASE/cfgtoollogs/dbua/SID/upgrade1 and you can see where it is set)
2) The post_upgrade_status.sql script in $ORACLE_HOME/sap/ora_upgrade/post_upgrade sets them when you run it as directed after the upgrade
3) The SBP post-patch instructions specify a command to run that sets these in the spfile
I don't think any of the upgrade steps regenerate the pfile, so if you're looking at one you generated pre-upgrade (like I did earlier today to pull out underscore parameters and user/background_dump_dest) that you then used to startup the database, SAP is definitely changing stuff behind your back. I'd just regenerate the pfile to avoid confusion.

Autonomous_transaction in oracle 11g

Hi
I am stuck with the concept of autonomous_transaction in oracle 11g. The situation is like that:
I have a table TABLE_A and i want to delete a row within it.
TABLE_A has a after delete trigger T_D_TABLE_A with autonomous_transaction property and it tries to delete a row in table TABLE_B.
TABLE_B has also a before delete trigger T_D_TABLE_B with autonomous_transaction and it raises application error when the reletad row is tried to be deleted.
So i want to delete a row in TABLE_A and and even if an application error is raised in the trigger T_D_TABLE_B, I want the row that i tried to delete in TABLE_A to be deleted.
Since I am using the autonomous_transaction property of 11g, I think the above code should behave like at my will but when i run it i encountered an application error that saying the row in TABLE_B can not be deleted and whole process even the deletion of the row in TABLE_A is rolled back. I think this is against the logic of autonomous_transaction property of Oracle 11g.
Can you help me with this problem?
Thanks in advance.
PS: if you request more detailed explanation about the problem, ı can provide the case environment and the code.

Oracle 11g decode issue with null

Hi,
we want to migrate from Oracle 10g to Oracle 11g and have an issue with decode.
The database has the following character set settings:
NLS_CHARACTERSET = AL32UTF8 in Oracle 11g and UTF8 in Oracle 10g
NLS_NCHAR_CHARACTERSET = AL16UTF16
If I try a select with decode which has null as first result argument I will get a wrong value.
select decode(id, null, null, name) from tab1;
("name" is a NVARCHAR2 field. Table tab1 has only one entry and "id" is not null.)
This select returns a value with characters which are splitted by 0 bytes.
In Oracle 10g the value without 0 bytes is delivered.
If I suround the decode with dump I get following results:
select dump(decode(id, null, null, name), 1016) from tab1;
Oracle 10g: Typ=1 Len=6 CharacterSet=AL32UTF8: 4d,61,72,74,69,6e
Oracle 11g: Typ=1 Len=12 CharacterSet=US7ASCII: 0,4d,0,61,0,72,0,74,0,69,0,6e
NLS_LANG has no effect on the character set of 'null' in Oracle 11g.
Non null literals work:
select dump(decode(id, null, 'T', name), 1016) from tab1;
Oracle 10g: Typ=1 Len=6 CharacterSet=UTF8: 4d,61,72,74,69,6e
Oracle 11g: Typ=1 Len=6 CharacterSet=AL32UTF8: 4d,61,72,74,69,6e
select dump(decode(id, null, N'T', name), 1016) from tab1;
Oracle 10g: Typ=1 Len=12 CharacterSet=AL16UTF16: 0,4d,0,61,0,72,0,74,0,69,0,6e
Oracle 11g: Typ=1 Len=12 CharacterSet=AL16UTF16: 0,4d,0,61,0,72,0,74,0,69,0,6e
Here the scripts for creating the table and the entry:
create table tab1 (
id NUMBER(3),
name NVARCHAR2(10)
insert into tab1 (id, name) values (1, N'Martin');
commit;
Is it possible to change the character set?
Could you please help me?
Regards
Martin

This doesn't have the problem.looks this doesn't solve the problem (of returning a value with characters which are splitted by 0 bytes):
SQL> select * from v$version where rownum = 1
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
1 row selected.
SQL> select dump(decode(id, null, null, name), 1016) from tab1
union all
select dump(case id when null then null else name end, 1016) cs from tab1
DUMP(DECODE(ID,NULL,NULL,NAME),1016)
Typ=1 Len=12 CharacterSet=US7ASCII: 0,4d,0,61,0,72,0,74,0,69,0,6e
Typ=1 Len=12 CharacterSet=AL16UTF16: 0,4d,0,61,0,72,0,74,0,69,0,6e
2 rows selected.You need to explicitly convert the third parameter to char:
SQL> select dump(decode(id, null, to_char(null), name), 1016) from tab1
DUMP(DECODE(ID,NULL,TO_CHAR(NULL),NAME),1016)
Typ=1 Len=6 CharacterSet=WE8MSWIN1252: 4d,61,72,74,69,6e

Oracle 11g: How to ensure the same transaction across several BPEL calls?

How to ensure transaction semantics across invocations of several BPEL services with a Database operations (Insert, update)? We are using transaction REQUIRED property in all of our BPELs. We are using webserive and JCA to access and modify the same row. Our code uses a combination of JCA, Spring bean, enity services, EJBs in these BPELs. The code can be more efficient, but, at this point, we have no option but to fix the transaction issue in this code. So, our question is how to ensure the same transaction context is used in all these BPELs to inser/update the same row? We have tried to set the GetUnitOfWork in the JCA Adapter but it did not provide any solution. Apaert from setting transaction in BPEL to REQUIRED and the JCA Adapter to use Unit of work, we are out of ideas. Any help is much apprecited. We are using Oracle SOA Suite 11g 11.1.1.5 version. --chary

Hi,
I can help you if you can describe the processes.
There can be some difficulties when you try to use the same transaction especially when you use many DB transactions & BPEL processes.
Using unit of work only ,might not be enough.
Thanks

How to set a default value to a transaction property?

Hi All,
I have a table in which one of the columns is production_date. I need to retrieve and display the data corresponding to the month as selected by the user in the front end. But prior to the selection, the user should see the data of the current month. I am able to show the data of the user selected month, but am unable to show the data of the current month. Instead of the current month, the transaction returns the data of the month of January by default. Can anybody help?
Thanks and Regards,
Lipsa.

Jeremy,
I am not at all bothered about the selected month. I think, you too did not get my question. Let me explain you the scenario once again.
In the left hand side of the user's dashboard, there is a link to view current status. Once the user clicks the link, he should see two things.
1. a chart to display the data of the current month.
2. a drop down list to select a month of his choice.
The data is available in the database table. This table is having a column called Production_Date. Once the user selects a month from the list, the selected item is set to an applet parameter. I have designed a BLS which calls the query template having this parameter. The QT queries for all the data from the database. The BLS is having a transaction property called 'month'. The parameter value is assigned to this property. Now, this property has the month selected by the user. Finally, I have the logic where I repeat the column Production_Date, get the month out of the date, compare the month with the property value in a conditional block, and get the data once the condition is true. Using these steps, I can get the data of the month selected by the user.
My issue is, the user should see the data of the current month prior to selection from the drop down list which I am unable to do. Any suggestions as to how can I achieve this?
Regards,
Lipsa.

Oracle 11g Installation How to select Database Character Set

Hi,
I am Installing oracle 11g R2. After installation I had verified the character set it was AL16UTF16 but I wants to set AL32UTF8 charater set at the time of oracle installation only. I can't see the character set setting opetion at the time of installation because I am selecting the installation option " Install database softerware only" and after installation of oracle software manually I am creating the database. Please help me how can I set the character set at the time of oracle installation or at the time of database creation.
My question is-
How can I set the AL32UTF8 character set in above scenario?
Why It is showing AL16UTF16 character set even I did not define any thing?

But is there any choice to set the NLS_CHARACTERSET at the time of manually database creation. Actually For creating the database i am using one shell script for seting the parameter values in init.ora file so can I set the parameter at that level(at the time of creating init.ora using manually database creation). like

Machine where the SQL Server database: IP Address is 142.120.51.30.
I've modified the tnsnames.ora to the following:

Transactional Behaviour of Oracle B2B 11g

Hi Gurus/Anuj,
Can you please explain Transactional Behaviour in Oracle B2B 11g?
For a Inbound Interface I have three Mediators(Mediator M1,M2 and M3)
Partner push a file at file location --> B2B Interface used in M1 ,through B2B Binding,picks the FIle and brings to SOA and--> Give it to M2 and M3.
I need to perform Error Handling in this case..
M1 M2 and M3 are Asynchronous,Synch and Synch in nature and I guess M1 will propogate it's transaction to M2 and M2 will propogate it's transaction to M3.
Routing rules are Sequential..
Note : Fault policies are applicable to parallel routing rules only. For sequential routing rules, the fault goes back to the caller and it is the responsibility of the caller to handle the fault.
Am I correct in understanding that :
B2B Adapter in M1 is the caller and M2 and M3 ,as being Synchronous,will follow M1'a transaction.
And if a Fault goes into M2 and M3,it will go back to the caller,means M1.
And in M1 we can have Fault-Handling.
Also please explain Transactional Behaviour in Oracle B2B 11g?
Is B2B is Asynchronous in nature?
Is B2B Adapter a Transactional Adapter?
What category of JCA adapter is Oracle B2B adapter?
Thanks
Vivek

Hi Vivek,
Also please explain Transactional Behaviour in Oracle B2B 11g?Oracle B2B depends upon the underlying transport being used for transactional behavior. As far as transaction propagation is concerned, we never had any such need in B2B communication.
Am I correct in understanding that :
B2B Adapter in M1 is the caller and M2 and M3 ,as being Synchronous,will follow M1'a transaction.
And if a Fault goes into M2 and M3,it will go back to the caller,means M1.
And in M1 we can have Fault-Handling.If you are using AQ interface of B2B adapter with XA Data Source then that adapter can participate in an XA global transaction that can span multiple resources. In this transaction, the application server acts as the coordinating transaction manager with multiple databases (or other resources such as JMS), each of which is involved in a single transaction.
If you are using JMS interface of B2B adapter with XA Connection factor then that adapter can also participate in an XA global transaction that can span multiple resources.
If you are using Default (Fabric) interface of B2B adapter then it does not participate in global transaction, rather it starts it's own local transaction and executes in that. So it will totally depend upon the interface you are using with B2B adapter that it will start and propagate a global transaction or will not participate in a global transaction. Moreover, if B2B adapter is starting a transaction and propagating it to a async service then that sync service will start a new local transaction and further sync services may execute in that transaction. As soon as the control comes back to B2B adapter, it will commit the transaction.
Is B2B is Asynchronous in nature?B2B can be used for both sync and async calls (between partners). B2B is async when communicating with middleware.
Is B2B Adapter a Transactional Adapter?Explained above
What category of JCA adapter is Oracle B2B adapter?No special category. It is a specific adapter for Oracle SOA SCA composites to facilitate them in communication with Oracle B2B. You may or may not use this adapter in SOA SCA composites.

How to generate TPC-E schema/data sets in Oracle 11g

Hi,
I want to use TPC-E schema in my Oracle 11g database (Standard) and also want to use DATA SETS from this benchmark for some kind of testing.
I've download EGen v1.8.0 from this TPC website:
http://www.tpc.org/tpce/default.asp
but don't know who to implement this benchmark database into my computer's database. I'll appreciate if someone please suggest me how to do this...
Thanks alot.
Best Regards,
Kamran

I want to find Optimal size of a data block size as this is the one parameter which can increase the performance of a database or decrease it.If there is a single optimal size, that would surely be the default Oracle block size - as Oracle should know perhaps better than any of us, just what block size differences do as it is their code that uses it?
Can I ask why you said that you would not have chosen this topic as a thesis?My leaning has always been to expert systems and A.I. Even designed and written my own expert system language years ago. One thing that is critical in such systems is how you structure data - and that has a nice database angle to it. One that I believe can still be exploited for research purposes.
Don't you think that it'll benefit DBA's or database developer after I reach a successful conclusion?To be honest, in the real world of database systems, the least of my concerns are data block sizes. For example, we're busy putting together a storage array that should have a maximum I/O pipe size of 40Gb. In comparison, we currently use dual 2Gb fibre channels on most of our servers for our I/O.
Technology moves fast. And perhaps there is an ideal block size for the standard storage array and Oracle instance today - but that could invalidated by new technology next year. Would I want to spend time and effort studying and analysing and researching a very specific technical subject, that perhaps is not considered as of that critical importance by DBAs and perhaps can be outdated with new technology and techniques?
I honestly do not want to put you off studying db block sizes. Perhaps there's still some critical issues to uncover in that respect. But personally.. there are many other subject areas in database technology that peak my interest a lot more. But then you have your personal preferences and likes and dislikes - and data blocks could be your muse. :-)

Unable to enlist in a distributed transaction (Windows7, Oracle 11G R1)

Hi,
I have a .Net application running on Windows 7 x64 using VisualStudio2008 and Oracle 11G R1 32bit client
In it I call a webservice calling another webservice, this requires to use oramts that interfaces with Microsoft DTC. However I'm getting the following error when calling the service method:
"Unable to enlist in a distributed transaction"
I have checked the following:
- Ora MTS is installed
- DTC is running, the security settings allow AX transactions (in fact I just allowed everything)
- Network services have the permission to access oracle dlls
- The registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI contains the following: "OracleXaLib"="xa80.dll" "OracleSqlLib"="SQLLib80.dll" "OracleOciLib"="oci.dll" (not sure if this is right)
What is it I'm doing wrong ? Does this version of Oracle work correctly on W7 ?
By the way it works fine on Windows XP !
I've spend quite some time trying to find a resolution..
Thanks!

I think I answered my own question
It seems that MSDTC is not supported by Oracle 11G R1 on Windows x64 !
All Oracle Database components are supported on Windows x64 with the following exceptions:
•Oracle Services for Microsoft Transaction Server are not supported on Windows Vista. As a result, all Oracle Windows data access drivers on Windows Vista that use Oracle Services for Microsoft Transaction Server to enlist in Microsoft Distributed Transaction Coordinator (MSDTC) coordinated transactions cannot participate in those coordinated transactions. These data access drivers include Oracle Data Provider for .NET, Oracle Provider for OLE DB, Oracle Objects for OLE, and ODBC. Check OracleMetaLink for up to date information on Oracle Services for Microsoft Transaction Server certification with Windows Vista.

Hi how to set the visible property in oracle adf?

Hi,
I am new to oracle adf in my application one of the field is id and it is sequence generated value Whenever I entered remaining values and click on save then only it has to display with sequence generated value before saving it has to be in hide mode. Can any one help me how the approach is.

As there are three ways through which you may pass a message to B2B, so there are three ways to set Action name property.
If you are using SCA/Fabric then set below properties -
b2b.fileName
b2b.contentType
If you are using JCA JMS adapter, then set below property -
jca.jms.JMSProperty.ACTION_NAME
If you are using JCA AQ adapter then set -
ACTION_NAME

Oracle 11g 64 bit - "Value too large for column" when setting Varchar2

Hello guys,
I have a machine running Oracle 11g - 64bits. And I have a table that contains a VARCHAR2(2000) field.
When I try to set the value of this field to a string that contains double byte characters, I get this error:
ORA-12899: value too large for column "QAPBG1220_11"."MYTABLE"."MYFIELD" (actual: 2433, maximum: 2000).
Although the value I'm setting is only 811 characters (€ sign).
The weird thing is that when I try to run the same query on another PC with Oracle 11g, 32 bits, It runs normally and the values are updated!!
Anyone has any idea about this? It's driving me crazy
Thanks in advance
Zahraa

COMMIT;
On the 32 bit, this works fine. I get the record with the values 1 and 2000 euro signs.
On the 64 bits, there is one machine (oracle 11.2.0.1.0) that adds the row, but when I view it, the value shows as "????"
and another machine (oracle 11.1.0.7.0) that throws an error:
- "String Literal is too long" : if there are more than 1333 euro characters
- Value too large for column .... : if there are less than 1333 and more than 666 characters.
Any ideas?

How to set Oracle 11g as Primary Oracle Home

Hi All,
I've Windows 7 operating system & have Oracle 11g client ( enterprise edition), Oracle 10g XE and Oracle Developer Suite 10g. I want to know how can I set Oracle_11g_home as my primary oracle home.
Note: Currently, the home of Oracle Developer Suite 10g is my primary home as it gets invoked whenever I type sqlplus in the command prompt or tnsping my remote database from command prompt.
Regards,
MK

You have two options. Either edit your %PATH% environment variable and place the Path related to your 11g home first. Another option is to add an ORACLE_HOME environment variable that points to your 11g home.
Hope this helps!
