CMR - two phase create ( ejbCreate + ejbPostCreate)
HI,
I have two tables. There is a CMR between the tables.
customer
customer_id (PK)
individual
individual_id (PK)
customer_id (FK)
It seems to me that when using CMR that
1. The foreign key is required to be optional.
2. The create process is a two phase operation, i.e. first create the base record using ejbCreate and then set up the relationship using ejbPostCreate.
Are the above two points correct?
If so ...I am in trouble, because my DBA ( quite rightly in my opinion) is refusing to make the foreign key optional...db integrity etc.
Is this a J2EE thing ....or an application server thing ( I am using OC4J).
hope I am making sense,
thanks in advance
Kevin
Hi,
The relationship must be initialized during the creation process. Typically, this is done in the bean implementation method ejbPostCreate().
When you create an entity for the state of New York, you must also create and initialize its relationship with the capital city of Albany.
The entity bean would not get inserted into DB until ejbCreate() and ejbPostCreate() methods are called.
Thanks.

Two phase commit and bean managed transactions
To all the Transaction GURUS!
Hi guys (-and gals).
I've been doing J2EE for quite a while, but today was my first at
XA-Transactions and Bean Managed Transactions.
Why am I doing this?
====================
Well I have to be able to controll the transactionalbehaviour of my
bean
during runtime, since some bean calls would cause a transactional
overflow due to the stress they would cause to the system, whereas
smaller bean calls need to run in one transaction.
-> Therefore I need Bean Managed Transactions
Since the bean does a call on two Database Connections it has to use a
XA-Transaction.
-> Therefore I need XA-Transactions.
Abstract
========
- I just can't get a User TransAction into the right Status it stays
in 'STATUS_NO_TRANSACTION' all the time
- Therefore the SQL Commands can be comitted 'java.sql.SQLException:
Does not support SQL execution with no global transaction'
- Therefore I can't do a rollback 'java.lang.IllegalStateException:
Transaction does not exist'
- Therefore I wrote this mail.
I don't want to be a smart-"ass" writing such a detailed and indepth
mail. I just would like to show that I tried, and would like to have
some replies from you guys.
Below are my configurations, code and logfiles.
Thanx for taking your time and hope that the other people may learn
something as well.

Scenario
========
used Software
Bea Weblogic (WL) 6.0 SPx (not real sure which SP i have)
Oracle 8.1.6 using the API-Version 8
I configured the system as follows:
(ofcourse I 'xxx'ed out all of the confidential data, sorry guys;-))
excerpt from:
config.xml
<JDBCConnectionPool CapacityIncrement="5"
DriverName="oracle.jdbc.driver.OracleDriver" InitialCapacity="2"
LoginDelaySeconds="1" MaxCapacity="5" Name="oraclePool"
Properties="user=xxx;password=xxx;dll=ocijdbc8;protocol=thin"
RefreshMinutes="5" Targets="fbsserver" TestConnectionsOnRelease="true"
TestTableName="languages" URL="jdbc:oracle:thin:@xxx:1521:xxx "/>
<!-- Since this is our Main Datasource I would not like to use a XA
Transaction due to performance Issues
and the TxDataSource:
-->
<JDBCTxDataSource EnableTwoPhaseCommit="true"
JNDIName="finstral.datasource.fbs" Name="finstral Content Datasource"
PoolName="oraclePool" Targets="fbsserver"/>
<!-- no comment required -I hope.
Next comes the "special" Pool
-->
<JDBCConnectionPool CapacityIncrement="5"
DriverName="weblogic.jdbc.oci.xa.XADataSource" InitialCapacity="1"
LoginDelaySeconds="1" MaxCapacity="2" Name="oracleSecurityPool"
Properties="user=xxx;password=xxx;server=xxx.xxx.xxx"
RefreshMinutes="5" Targets="fbsserver" TestConnectionsOnRelease="true"
TestTableName="Users" SupportsLocalTransaction="true"/>
<!-- Well since there can only be one none XARessourceManager involved
in a 2PC
(keyword: Two Phase Commit) I will have to use a XACapable Driver for
the other
Datasource. Due to all the bugs in the oracle.xxx driver. I'll be
using the jdriver for oci.
I activated 'SupportsLocalTransaction' hoping it would solve my
problem - without effect. I just left in there now, since it made
sense me. Not?
Again the TxDataSource:
-->
<JDBCTxDataSource EnableTwoPhaseCommit="true"
JNDIName="finstral.datasource.fbssecurity" Name="finstral Security

CONCLUSION
==========
I'm going nuts.
I just don't get it.
The transaction is the same. I don't change the Connection. I start
the Transaction at the beginning before I do anything!
Please guys help me out.
Thx alot.

Hi Priscilla
(did you ever see the movie ? :-))
Well I moved away from the idea of using bean managed transaction. I'll
be using Container Managed Transactions. To modify the
transactionalbehaviour I'll write proxymethods which have certain
different containermanaged transaction properties, but which all call
the same private methods.
But it works! Here is my experience:
- I was doing a DDL statement: I was trying to create new Tables, which
is a definite "no-go"
- pay careful attention to:
http://edocs.bea.com/wls/docs60/jta/trxejb.html#1051405
and
http://edocs.bea.com/wls/docs60/jta/trxejb.html#1051741
and use these Settings for the Pool, don't ask me why, but it took me
hours to find it out by myself:
<JDBCConnectionPool CapacityIncrement="5"
DriverName="weblogic.jdbc.oci.xa.XADataSource" InitialCapacity="1"
LoginDelaySeconds="1" MaxCapacity="2" Name="oracleSecurityPool"
Properties="user=xxx; password=xxx; server=xxx.xxx.xxx"
RefreshMinutes="5" Targets="fbsserver" TestConnectionsOnRelease="true"
TestTableName="Users" SupportsLocalTransaction="true"/>
where as the server (shown as: xxx.xxx.xxx) is the TNS Name of the
Oracle Driver.
It works great.
Another thing you guys might want to do is write a simple StatelessSB
which does JDBC calls and two different database Connections.
Then write a UnitTest which calls this bean a couple hundred times (with
the same transaction). Have one test do clean writes, and another which
causes some SQL-Exception (too long Data Columns, or likewise).
Always count the entries and see if everything worked out. We're using
this SetupConstruction to test new combinations of AS(sorry Priscilla) /
Database / Db-Drivers to have a "standard test".
I know my two cents were uncalled for, but it might save you some
time.....
thanx for your help
Stefan

Hi Stefan,
Looks like you have not actually begun a transaction by calling
UserTransaction.begin(),
so your setupTables method is really executing with no transaction
context.

How to connect two phases in the phases in one PI sheet. ?
Hi Gurus ,
I have created one control recipe for the one material . In which one operation & two phases are there. For the two phases different control recipe destinations are used.
But when i am creationg process order , two PI SHEETs are creating having same process order no for the two different phases.
My requirement in one PI SHEET both the phases should be included.
So please reply me .
AbhiHy Abhi,
Answer is already there in your Question itself.
For the two phases different control recipe destinations are used.
system will generates control recipe Control Recipe wise for a Process order.Meaning is if your Master Recipe / Process order contains 2 Control Recipe Destination then system will generates 2 Control Recipe.which contains the related PI category assign to that relevant phases.
So if You want only one control Recipe then you have to use only one Destination in your Master Recipe / Process order.

Dhaval

How to consider substitute component under two-phase plan(MPS vs MRP).
We try to run two-phase plan: Production plan and Manufacture Plan in ASCP.
We hope our planner can review production plan result and modify system suggestion date or qty for assemble component plan order.
Then we run Manufacture plan setting demand source is from production plan and "use substitute component" is checked in decision rule, we hope this Manufacture plan can consider substitute component.
But the Manufacture plan didn't consider substiute component.
How to make Manufacture plan consider substiute component when we set demand source is from production plan .Stacey,
I understand your requirement. I also believe that the manufacturing plan should be able to plan substitute components, but it would take quite a bit of analysis to understand why it was not working correctly. If you want to pursue that approach, I would recommend you start a SR with oracle support to troubleshoot.
The most typical approach with two plans is to have the production plan constrained and attempt to use available substitute components marked as critical. If that is the case, these "critical item" orders would not be replanned in the second plan. Your purchasing planner would not be able to firm planned orders in the second manufacturing plan, but could only update dates and release from that plan. At best case, any changes would be overwritten entered by the purchaing planner for items controlled in the production plan would be overwritten in the next cycle.
The best use of a two plan approach is to simplify constrained planning efforts by have a second unconstrained plans for most items and a smaller constrained plan driving the process. That is not your intent, so you might want to stay with one plan. You will always have some lag in these planners actions in a two plan process, so I don't know if this approach is driving any real benefit for you from a one plan approach. In either approach you will have planners stepping on each other and having to review exceptions, or better yet... talk to each other to review plans.
So...
1. If your intent is to limit the complexity of the constrained plan, the two plan approach has benefits
2. If point # 1 is not your intent, and you are focused on allowing planners to react faster and communicate with each other as they plan their schedules, stay with a one plan approach.
You said
"Our planner will release the plan orders which suggest start date is inside two weeks. But when they review the result and release the plan order , purchase planner review the same plan and issue purchase request in the same time. It will happen some problem, purchase planner will obey system's purchase suggestion but can't meet the demand of those plan orders that production planner has released."
An assembly planner should not be releasing orders within two weeks when the materials are unavailable. That should not happen with a constrained plan unless they created an override the system recommendations. With unconstrained plans, the best you can do is implement a time fence control to prevent this and review exceptions.
I think the best you can do here is implement this process as constrained with substitutes considered for the Assembly planner. Then usining one plan, have the purchasing planner implement their orders based on the latest information. They should use safety stock planning techniques and be looking at a lonegr horizon for demands. They should also communicate these plans to each otherKevin -

This problem normally arises with the wrong combination of JDK and OS and for the Linux machines, its better to use IBM Java instead of SUN java
I remember that I have solved this type of problem by using lower version of IBMJava2-AMD64-142-SDK-1.4.2-10.0.x86_64.rpm which is SR10. You can download this version from
http://www.ibm.com/developerworks/java/jdk/linux/download.html
go to download _12 and then just change the sr12 to sr10 in the header url....

what I suggest you is to start reinstallating SolMan after installing IBM java sr10 version...

SAPinst error during phase Create DB statistics (sapcheck)

I've checked this directory and I did not find the folder sapcheck. that is because my sapcheck is located in a different drive (E:). why is sapinst looking at the wrong directory and how can i point sapinst to use drive E instead?
i was thinking maybe i could copy the folder sapcheck from drive E to drive d and continue with the installion. what will be its impact if i do this?
by the way, my OS is windows 2003.
please advise.
thank you very much!

It seems that while defining the Path of SAP and Oracle there is something wrong that's the reason it is looking somewhere else. If you will copy from E Drive installation will continue but it will be keep searching on D drive everytime. As you are on initial stage to install a new System i would suggest to stop the installation Master and start it from Scratch and define the FIle System Directly once again as you want.

Netweaver 2004S Installation stops in phase 'Create Java Users'.
Hi,
We have an error in the installation of Netweaver 2004s on an Solaris X64 10 (64 bit). We have j2sdk1.4.2_13 (32 bit installed)
In phase 'Create Java Users' , we receive the following error in dev_UserCheck.clone :
'*** ERROR => DlLoadLib: dlopen()= ld.so.1: jlaunch:

[Thr 4] *** ERROR => Can't load VM shared library (libjvm.so) (rc=-2)

I think this is an java error.
We can't find a download for the 64 supplementation package for solaris
X64. Is this supported?
Kind regards,
Serge SchellesHi Serge,
I'm no Solaris expert, but if I'm not mistaken, JRE and JDK versions for the X64 platform are only available as of version 1.5. It's worth a try, you can run them both at the same time on the same server. Just point your JAVA_HOME to the 1.5 directory after installation and start SAPinst again.
Good luck!

How to recover in a two phase commit ?
I am implementing a two phase commit with Oracle XA in Oracle 8.1.6. I am wondering how I can recover from failures occur between the PREPARE and the COMMIT stage. If I lose the database connection after the changes have been prepared, then I can't find a way to rollback or commit the changes.
Appreciate any helps.
SamThe iPod OS takes care of where/how to store the files on the iPod and it has not done this. This is why you need to get the files off your iPod first.
My goal is to connect my iPod to my Mac, launch iTunes, and all of what's on my iPod displays in iTunes after single-clicking the iPod's icon in the Source pane of iTunes' window.
This is very, very simple. This is how iTunes works normally.
Since you now have the stuff from your iPod on your computer (using Ollie's iPod Extractor), load them into iTunes.
Sync them to the iPod. This will update the iPod database so all of the files are seen/identified correctly by the iPod.
Set the iPod prefs in iTunes to manually update.
Now you can delete the stuff on your computer and iTunes and view/edit/delete the stuff on the iPod using iTunes.
The outcome of using the utilities suggested in previous posts is that all of what's on my iPod gets copied to my Mac's hard drive (which is not what I'm trying to accomplish) and then that displays in iTunes' Library.
Only because the files on the iPod are not "useable" with the iPod or iTunes right now.
This is not something you will have to do everytime.
Once you get them on your computer, you can do the above steps and you will not have to use any utilities.
Just use iTunes. -
Using two daqmx create channel to acquire signals in random
Hi
I am trying to acquire signals from PXI 4472 with two DAQmx create channels. The channel selection is random. For eg. first create channel i have ch. 0, 2, 4, and 6 and the other create channel is Ch. 1,3,5 and 7. This I can do, but the problem is that I need to write the acquired data in seperate files for each channels and that too in sequential order. How can I do that. I know i need to use the loop but how will I will select the channels from two different task.
Thanx in advance
NitinOk, here was my idea, I am not sure if it will work for you or not after looking at your VI.
You can use some of your subVIS that you made to make the path different for each file. But what I had in mind for the channels was what I did in the vi i attached. You can just repeat the process for each of the channels and you would know that they were saved correctly. You could also feed in the iteration number of the main VI while loop to have the binary files change sequentially (ie, data1, data2, etc).
Again, this may not be a route you want to take, you may have other ideas.
Ill try to work on it some more later, but I have to get back to work for now

Configuration of two-phase-commit in OC4J 10.1.2
Configuration of two-phase-commit in OC4J 10.1.2 in application with multiple modules
We have an application ear file consisting of ejb-modules (mdb and slsb) and two web-modules. We are using Oracle's advanced queueing for messaging and CMT (all ejb use the Required transaction attribute). We need different datasources (OrionCMTDataSource) including that for aq, so we need two-phase-commit. The web clients use ejbs and browse the messaging system. Our 'orion-application.xml' includes a commit-coordinator configuration, and the database is setup correctly. The configuration works fine for mdbs, when sending messages to the queues. When a client starts after messages have been sent and consumed by the mdbs, oc4j complains that no commit-coordinator is defined in 'server.xml'. If we start the client first, it can access the queues, but then the mdbs complain. It seems that the first one "gets" the commit-coordinator and the second one fails.
Some questions:
Why isn't the second client type using the commit-coordinator configuration of the "orion-application.xml"?
Is such scenario not supported by OC4J?
How can I setup the application correctly?
How do I configure commit-coordinator with different datasources to the same database? (Commit-Coordinator is also this database)Take a look 'How to Use a Custom Serializer with Oracle Application Server Web Services' [1].
In your case, you should be looking at BeanMultiRefSerializer (org.apache.soap.encoding.soapenc), which will serialize your data using href and providing a way to deal with cycles.
All the best,

Two Phase Commit on Slow Network

Now if I try to ping service on other PC using TNSPING it gives me connection timed out, how should I tackle this issue ?
Hi Ioakim
Performing an atomic transaction(ACID) that spans a source system, BizTalk and then a different destination system is not possible. This is due to the nature of distributed transactions - it may not be practical to hold locks on resources(needed for atomic
transactions) that are spread across different networks. Given that there is no guarantee that the resources may be released in a reasonable amount of time, transactions in BizTalk can only be scoped to and from the BizTalk MessageBoxDb. Or in other words,
you can read a record to BizTalk transactionally and on the send side, send a message from BizTalk transactionally.
However, you can simulate/fake atomic transaction characteristics(although tricky) using compensation logic within BizTalk orchestrations. So, lets say you read+delete a record from SystemA into BizTalk, and that record has to be updated in SystemB.
If for some reason the insert to SystemB fails, you would have to write custom logic in a compensation block that then performs the reverse operation in SystemA - i.e., it inserts back the record in SystemA in this case. So, using compensating actions, it
is possible to ensure that all the systems involved are transactionally consistent at the end of the day.
There's an article from C.Young that discusses this in some detail-

I am seeing the following exception. Please let me know how to fix this.
thanks
Sunita
com.sap.engine.services.connector.exceptions.BaseResourceException: The resource "xxx" does not support two-phase commit and cannot be enlisted in the current transaction, because another non supporting two-phase commit resource is already enlisted for component "webContainer/applications/JavaEE/YY-TPRO/YYr-TPRO" in application "JavaEE/YY-TPRO". Only one of the enlisted resources is allowed to be non two-phase commit compliant.

Thanks for the response, I already went through these threads.
My exception seems to be related to this - Problem with connection sharing if J2EE transaction is running
and suggested solutions seems to be:
The problem is caused when there is an inappropriate attempt to open a second connection in an active JTA transaction. There is either an attempt to get a second connection from an un-shareable non-XA DataSource or an attempt to get it from another non-XA DataSource. You have to:
● Use no more than one connection from this data source while the JTA transaction is active or
● Declare the data source as shareable, depending on your application logic.
Question is, How can I make data source as shareable??
This application worked fine in JBoss, weblogic and now we are trying to port it to NetWeaver.
Is any of the above options are configurable in data-sources.xml?
Thanks for your guidance and response.

SAP Transaction in Two phase Commit ?
Hi all,
When we make a connection to SAP system from .NET application using .NET connector, we can make calls to transactional BAPI/RFCs. But is there any way in which we can make SAP transaction take part in MS DTC (Microsoft Distributed Transaction Coordinator) transactions?
We want to implement a two phase commit and hence this question. Please let us know if you are aware of any mechanism using which we can implement a two phase commit.
The call scenario is described below:
TransactionScope
1. SQL_StoredProc1();
2. SQL_StoresProc2();
10. SAP_TransactionBAPI();
11. SQLStoredProcn();
12. SQLTransaction_Commit();
13. SAPTransaction_Commit();
Exception ()
SQLTransaction_Rollback();
SAPTransaction_Rollback();
In the above case all the statements have to be executed successfully or they have to be rolled back. Lets think of the situation where all the statements up to line 13 have been executed successfully, but there was a failure during the commit of SAP, and then we have to rollback the SQL transaction also which is already committed.
This situation can be handled if and only if SAP transaction manager follows XA transaction protocol and it can include itself in MSDTC. So that every transaction manager votes for the commit (it can be called half commit) if the transaction is successful otherwise all the transactions should be rolled back.
Can anybody tell me the way to include SAP transaction manager in MSDTC if it at all possible?Hi Saket,
I did not understand much of your query but just wanted to know how are you making a connection to the backend here?
If using DataSources and if the datasource is configured directly in the EP server (using Visual Administrator), you have an option of the required 2-way commit.
The datasource takes care of it directly. Apart from this, the datasource will also take cre of the connection pooling.
Hope this helps.
Awaiting Reply.

ECC5 installation error during phase "Create Database"
We are installing ECC5 on IA64 using Oracle 9207.
At phase 'Create database' the sapinst aborts reporting errors executing the oradim -NEW SID command.
The oradim.log contains one row only : "DIM-00019: error creating service".
The OracleServiceSID is created, but it does not start.
If we try to run manually the command "Oracle.exe SID", so the same command that is started by the OracleServiceSID service a popup appear saying:
"The entry point kdr9ir2_pop could not be located in the dynamic link library oracle oracommon9.dll"
Any idea ? Are there problems with the oracle 920 sw installation or what ?
regardsHi,
Sounds like oracle problem.
- Please post the last few error statement from sapinst_dev.log.
- Check if the the following key is in the registry:
HKEY_LOCAL_MACHINE\system\currentcontrolset\services\OracleService
- check oracle alert<SID>.log, see if there is any significant errors.
- see note #602843
- if "DIM-00019: error creating service", does it mean that an Oracle service with the same SID already exist? if so, use command "sc delete [service name]" to delete the service and then restart the installation.
Hope this helps.
cheers,
Vincent
