Oracle Performance linked to book assignment

HI,
I have a question about Siebel On Demand performance.
I would like to use book functionality to manage visibility for my company. My organization is quiete complex and I need to create more than 1000 book. So to manage book assignment, I have to create more than 2000 workflows (one for creation, one for modification) per Object.
Do you think there is a risk of performance using so many workflows?
Is it possible to use Territory functionality to manage users visibility on a record?
Regards,

I would recommend using Book of Business to manage visibility for your company. It is not possible to use territory functionality to manage users visibility on a record.

The operation could not be performed because OLE DB provider "OraOLEDB.Oracle" for linked server ...

Our setup is that we have two databases; a SQL Server 2008 database and an Oracle database (11g). I've got the oracle MTS stuff installed and the Oracle MTS Recovery Service is running. I have DTC configured to allow distributed transactions. All access to the Oracle tables takes place via views in the SQL Server database that go against Oracle tables in the linked server.
(With regard to DTC config: Checked-> Network DTC Access, Allow Remote Clients, Allow Inbound, Allow Outbound, Mutual Authentication (tried all 3 options), Enable XA Transactions and Enable SNA LU 6.2 Transactions. DTC logs in as NT AUTHORITY\NetworkService)
Our app is an ASP.NET MVC 4.0 app that calls into a number of WCF services to perform database work. Currently the web app and the WCF service share the same app pool (not sure if it's relevant, but just in case...)
Some of our services are transactional, others are not.
Each WCF service that is transactional has the following attribute on its interface:
[ServiceContract(SessionMode=SessionMode.Required)]
and the following attribute on the method signatures in the interface:
[TransactionFlow(TransactionFlowOption.Allowed)]
and the following attribute on every method implementations:
[OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = true)]
In my data access layer, all the transactional methods are set up as follows:
using (IDbConnection conn = DbTools.GetConnection(_configStr, _connStr))
using (IDbCommand cmd = DbTools.GetCommand(conn, "SET XACT_ABORT ON"))
cmd.ExecuteNonQuery();
using (IDbCommand cmd = DbTools.GetCommand(conn, sql))
... Perform actual database work ...
Services that are transactional call transactional DAL code. The idea was to keep the stuff that needs to be transactional (a few cases) separate from the stuff that doesn't need to be transactional (~95% of the cases).
There ought not be cases where transactional and non-transactional WCF methods are called from within a transaction (though I haven't verified this and this may be the cause of my problems. I'm not sure, which is part of why I'm asking here.)
As I mentioned before, in most cases, this all works fine.
Periodically, and I cannot identify what initiates it, I start getting errors. And once they start, pretty much everything starts failing for a while. Eventually things start working again. Not sure why... This is all in a test environment with a single user.
Sometimes the error is:
Unable to start a nested transaction for OLE DB provider "OraOLEDB.Oracle" for linked server "ORACLSERVERNAME". A nested transaction was required because the XACT_ABORT option was set to OFF.
This message, I'm guessing is happening when I have non-transactional stuff within transactions, as I'm not setting XACT_ABORT in the non-transactional code (that's totally doable, if that will fix my issue).
Most often, however, the error is this:
System.Data.SqlClient.SqlException (0x80131904): The operation could not be performed because OLE DB provider "OraOLEDB.Oracle" for linked server "ORACLSERVERNAME" was unable to begin a distributed transaction.
Now, originally we only had transactions on SQL Server tables and that all worked fine. It wasn't until we added transaction support for some of the Oracle tables that things started failing. I know the Oracle transactions work. And as I said, most of the time, everything is just hunky dorey and then sometimes it starts failing and keeps failing for a while until it decides to stop failing and then it all works again.
I noticed that our transactions didn't seem to have a DistributedIdentifier set, so I added the EnsureDistributed() method from this blog post: http://www.make-awesome.com/2010/04/forcibly-creating-a-distributed-net-transaction/
Instead of a hardcoded Guid (which seemed to cause a lot of problems), I have it generating a new Guid for each transaction and that seems to work, but it has not fixed my problem. I'm wondering if the lack of a DistribuedIdentifier is indicative of some other underlying problem. I've never dealt with an environment quite like this before, so I'm not sure what is "normal".
I've also noticed that the DistributedIdentifier doesn't get passed to WCF. From the client, I have a DistributedIdentifier and a LocalIdentifier in Transaction.Current.TransactionInformation. In the WCF server, however there is only a LocalIdentifier set and it is a different Guid from the client side (which makes sense, but I would have expected the DistributedIdentifier to go across).
So I changed the wait the code above works and instead, on the WCF side, I call a method that calls Transaction.Current.EnlistDurable() with the DummyEnlistmentNotification class from the link above (though with a unique Guid for each transaction instead of the hardcoded guid in the link). I now havea DistributedIdentifier on the server-side, but it still doesn't fix the problem.
It appears that when I'm in the midst of transactions failing, even after I shut down IIS, I'm unable to get the DTC service to shutdown and restart. If I go into Component Services and change the security settings, for example, and hit Apply or OK, after a bit of a wait I get a dialgo that says, "Failed ot restart the MS DTC serivce. Please examine the eventlog for further details."
In the eventlog I get a series of events:
1 (from MSDTC): "The MS DTC service is stopping"
2 (From MSSQL$SQLEXPRESS): "The connection has been lost with Microsoft Distributed Transaction Coordinator (MS DTC). Recovery of any in-doubt distributed transactions
involving Microsoft Distributed Transaction Coordinator (MS DTC) will begin once the connection is re-established. This is an informational
message only. No user action is required."
-- Folowed by these 3 identical messages
3 (from MSDTC Client 2): 'MSDTC encountered an error (HR=0x80000171) while attempting to establish a secure connection with system GCOVA38.'
4 (from MSDTC Client 2): 'MSDTC encountered an error (HR=0x80000171) while attempting to establish a secure connection with system GCOVA38.'
5 (from MSDTC Client 2): 'MSDTC encountered an error (HR=0x80000171) while attempting to establish a secure connection with system GCOVA38.'
6 (From MSDTC 2): MSDTC started with the following settings: Security Configuration (OFF = 0 and ON = 1):
Allow Remote Administrator = 0,
Network Clients = 1,
Trasaction Manager Communication:
Allow Inbound Transactions = 1,
Allow Outbound Transactions = 1,
Transaction Internet Protocol (TIP) = 0,
Enable XA Transactions = 1,
Enable SNA LU 6.2 Transactions = 1,
MSDTC Communications Security = Mutual Authentication Required, Account = NT AUTHORITY\NetworkService,
Firewall Exclusion Detected = 0
Transaction Bridge Installed = 0

This makes me wonder if there's something maybe holding a transaction open somewhere?

Searching book "Oracle performance 11G - Self study guide"

Hello all,
I'm searching hardly the course "Oracle performance 11G - self study guide" to download.
It's shorter and speaks about the essential things ... unlike the standard guide "Oracle® Database Performance Tuning Guide 11g Release 2 (11.2)"
I's impossible for me to buy it, because of his price about 1500$.
So I'm asking if someone can lend it to me, or tell me where I can download it ...

Oracle Performance Management doubts

Hi All,
I have some questions related to Oracle performance management and hope they will get answered over here:-
Que1. The weight of all objective should be 100 but in my case it is allowing any value. What I need to do to restrict it?
Que2. Can we do objective setting and Appraisal process simultaneously? That would be allocate objective and rating in parallel?
Que3. When and how the rating provided by manager would reflect in the Performance (People --> Assignment --> other --> Performance) widow and what would be the effective date. I have completed all setup and process but the final rating is still not available.
Que4. What is difference between Talent management, Performance management and Workforce performance Management?
Que5. When I include the Appraisal in the PMP and select the Appraisal template (that just has final rating) and click on the "Go to Task" against "Manage appraisals" (to initiate it) I do not see anything. Do we/manager need to create plan every time using the link Appraisal.
Sorry for asking too many questions.
Thanks,
Avinash

Que1. The weight of all objective should be 100 but in my case it is allowing any value. What I need to do to restrict it?
ANS : This is a seeded one. If you want to restrict it you have to customize the page.
Que2. Can we do objective setting and Appraisal process simultaneously? That would be allocate objective and rating in parallel?
ANS : There is a checkbox "Allow Objective Setting outside of the period" (something like that).
Que4. What is difference between Talent management, Performance management and Workforce performance Management?
ANS: AFAIK, Oracle Talent Management and Oracle Performance Management are same. Prior to Oracle Performance Management, the module name was Oracle Talent Management.
Que5. When I include the Appraisal in the PMP and select the Appraisal template (that just has final rating) and click on the "Go to Task" against "Manage appraisals" (to initiate it) I do not see anything. Do we/manager need to create plan every time using the link Appraisal.
ANS : You can schedule the concurrent program, "Mass Appraisal Creation".
Hope it helps!.

this perticular part is raising that error, and i had tried every configuartion on my local machine related to MS DTC.
When i remove my transaction code, its work just fine no exception raise, but when i use then i.e. BEGIN TRAN, COMMITE TRAN, AND ROLLBACK TRAN. its giving me error, other wise its fine.
Please Help or disscus or suggest why my transaction base code is not woking????
thanks in advance.

Competency Weight age- Oracle Performance Management

Dear All,
We are in the process of implementing Oracle Performance Management (12.1.3 Ver), these are following scenario we need to address. Kindly post your advice .
1.     We have 4 Objective ( Objective-1, Objective-2, Objective-3 and Non-Bonus able Objective) for all the employees with weigh age. We need to restrict the weight age and the sum of all the Objective weight age should not exceed 35% . (EX: Obj 1+ Obj 2 + Obj 3+ Non-Bonus able = 35%). How to achieve this?
2.     We have 4 Mandatory competency and for which we need to provided weight age for each competency ( Ex: Communication Skill -20% weight age & Team work – 30%) How to achieve this?
3.     Our final rating works as, Objective Rating + Competency Rating ( Final Score = Objective Rating + Competency Rating). How to achieve this?
4.     We have another requirement like we need to Tag Absenteeism Rating ( Please see the below rating scale) along with the Final Appraisal rating . I am furnishing the Rating details
Excel----------Never Absent and always punctual.
Achieved----Never absent but late in or early out with prior permission.
Partial ------ Deduction of 5%     Few Absent or late in or early out without prior permission or advance intimation.
Not Achieved ----- Deduction of 10%     Multiple Absent or late in or early out with no permission at all.
Please let me know if you need more information
Thanks and Regards

Oracle performance against other DBMS

I would like to ask for some advice about Oracle overal performance, comparing with other databases. I was using MySQL and MS SQL.

How to execute remote query by Oracle Database Link

I use Oracle Database Link to query data from SQL Server. The query is like:
select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*
tableA and tableB is large and the result is relatively small. This query executes quickly in SQL Server since indexes are built both on the two tables. But it is very slow on Oracle Database Link to SQL Server.
I guess the join operation is performed on Oracle side not on SQL Server side, thus the indexes are not used. Since I just need the joined result, I prefer to perform the query entirely on SQL Server and get the small result only. But I have no privilege to create views on SQL Sevrer.
I konw that using SQL Server's linked server and OPENQUERY function can achieve this goal. I wonder how to do this on Oracle Database Link. Thanks!

DO NOT DO THIS....specifically:
"select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*"
You would be better off to do the following:
create a Materialized View in Oracle and once/day (or as frequently as you feel necessary) pull the data from SQLServer and then do the join locally by creating MV as TABLEA_MV and TABLEB_MV and then have views that have the REALTABLEA and REALTABLEB names that point to these MVs. This can be done without recompiling or changing your code. Trust me, I have seen this sort of thing in the past that completely crippled an IBM mainframe using DB2 along with a major network segment by having this sort of join via DB links. You must understand the ramifications of your "design" and I can tell you for certain that it is a very BAD!!! idea... Fix this before you are issuing another command: "alter DBA update resume/CV;"
The app went into production at 7AM. By 9:30AM, the mainframe had executed more than 10Billion I/O's. It took > 15hrs for the mainframe to recover once we shutdown the app and implemented the view/MV described above.
I will leave it as an excercise for the OP to develop the syntax for this.

Regarding iTunes U courses, would I be able to link to books/sites (like say an amazon hardback book or link to a kindle book they can purchase and download). Considering that not all books are available on iBooks I'm hoping this is allowed.   Also the possibility on monetizing since amazon gives commission for linking.
This question is for both the uncredited (private) courses and the bigger accredited accounts.    I am a developer trying to learn how to help my area schools and also have some ideas for my own courses.    Obviously keeping within the iTunes U app would be preferred in most cases (to the learning experience) since they can take notes and see them within the app itself.
If the reply comes from a non-apple employee please let me know (or better yet, link to) where that is clarified.   I would hate to develop something just to later find out it is against the apple iTunes U agreement.

Fair question
And, to be even more fair, I have to tell you that I get that every single day. And it's getting worse (or better, depending on how you look at it).
I always try to let people know it's a long way until you get to a confortable point, a point where you can create something. And that's exactly what I am trying to do, or at least asking how/if I should do it. And then I let them know where to start. That's what I want.
Thanks.

Help needed with variable - trying to get data from Oracle using linked svr

Sorry if I posted this in the wrong forum - I just didn't know where to post it.
I'm trying to write a simple stored procedure to get data from an oracle database via a linked server in SQL Enterprise manager. I have no idea how to pass a variable to oracle.
Here's how I would get the variable in SQL:
declare @maxkey INTEGER
select @maxkey= MAX(keyfield) from [server].Data_Warehouse.dbo.mytable
select * from [server].Data_Warehouse.dbo.mydetailtable where keyfield=@maxkey
the select statement I need to do in oracle would use that variable like this:
select * from OPENQUERY(OracleLinkedServer,'select
* from ORACLEDB.TABLE where keyfield > @maxkey')
and I get this message: OLE DB provider "OraOLEDB.Oracle" for linked server "OracleLinkedServer" returned message "ORA-00936: missing expression".
I realize that I can't pass the @maxkey variable to oracle - so how do I accomplish this?

Please refer the example in this link which deals with Oracle date format.
You can finnd a command DECODE which is used for date formats. If you have a look at whole theory then you will get an idea.

How to improve my performance activities on Oracle server.
Please guide me regarding this issue.
If anyone wants more info, please let me know.
Best regards,

Are you sure that it is not an application constraint ? i.e. the application can't handle so much data per second ? (application locks, threads )
Have you tried to write a simple test program, which inserts predefined data (which your application inserts) the same data, only changing keys ?
Then comparing the values from the 1st and the 2nd configuration ?
Did you check the way your application is communicating with oracle ? If it is TCP/ip (even on the local machine) then this is your main problem.
And one more thing, do you know if your application is able to run the load (inserts) of data on different threads (i.e. in parallel), because if is not, you won't be able to push the speed higher because your constraint is the speed of a single CPU. Consider running several process, which loads the data.
We had the same problem ot AIX machines with 4 cpus. Monitoring the machine, we found that only 25% (1 cpu) where in use. We had to run 4 processes to push the speed up. Check your system's overal load while running the 'load' (inserts).
log_checkpoint_interval = 10000
Check if this value is appropriate. Maybe you should set it to 0 (infinite). This will disable checkpoints on a 'number of undo record' basis. Checpoints will occure only on log switch.
How much redo files per redo groups do you have ? What is their size ? Are they on different disks ? How much redo data is generated by a single 'record' inserted ?
Hope i helped at least a little.
