DbAdapter (nolock in merge operation)

Hello,
I'm currently with performance problems when I do various operations on a SQL Server 2000 using a dbAdapter(merge operations).
I did some analysis in the database and realized that I am having lock in "select" operation, and I have to wait for the "update". How can I add the command "nolock" at the end of this query?
Thanks
Zanatto

Yes, this is to prevent confusion when the merge result falls outside of the active filter and is thus hidden from the user. Sometimes it will, sometimes it won't - so we chose consistency of behavior.
You should be able to prevent this by clicking the padlock icon in the upper right of the grid view and filter area. This will lock the filter.

DBAdapter merge operation error

Hello,
I run into a problem when trying the DBAdapter merge operation. I believe the merge operation first executes a query operation based on the primary keys, if not found, then will execute an insert operation, my problem is when I pass in the input as " " for one primary key, seems the merge operation internally transform it to "" then do the query, so there is no record found, then it will do the insert with the right primary key " ", which results in the violation of the unique constraint (suppose I inserted a record with primary key " " before).
Does anyone have any suggestion for this?
Thanks.
Leo

I'm using database triggers as well, if your acquanted with pl/sql that would be the 1st choice, especially because you can generate the needed triggers for all your audit columns.
On the other hand you can define annotations in JPA, EJB3.0 now to populate your audit-columns automatically, maybe this can be done as well in the toplink mapping files?
It should be possible, but I don't now until which level annotations are supported in toplink used by the dbAdapters.
Kind regads,
Nathalie

Error in Database Adapter Insert Or Update (Merge) Operation

I have a simple SOA composite which reads XML files and posts data to a database table using a database adapter. I would like to perform a merge operation but I keep getting this error in the log -

The INSERT operation works fine with the database adapter, but I cannot get MERGE and UPDATE operations to work as expected!
Thanks.

hi Sudeep,
We are at first hand struggling with DB adapter problem getting down everytime. Don't know the reason why.
DB adapter is in down state and when trying to make it up gives below error:
"weblogic.application.ModuleException: weblogic.connector.exception.RAException: Jndi Name is null or empty."
I just created a simple sync process using DB adapter (custom select) and deplyed successfully. I hope jndi name is not to be configured in weblogic-ra.xml file.
This is the first time we are using this JNDI name (eis/DB/calvindb).
Any inputs will be appreciated.
Thanks,
Nikhil

How to perform merge operation using Data services designer?

I am new here and new to Data Services Desinger as well.
And currently, I want to do a merge operation using query transform or table comparison transform. But sadly, neither one of them is giving me what I want.
So, wonder if you could help clarify if either one of them could achieve MERGE operation between and source and target tables?
if positive, then how?
PS:
by MERGE, i mean, if data exists in target table, then only do update, else, do insert. same with the standard MERGE operation of oracle.
If you need any more info, let me know!
Thanks in advance.

You can do this.
You don't need the Tabe_Comparison transform actually.
Just query the data you need and output the flow from your query to your target table.
Then, you'll have to check the "Auto correct load" option: this will insert new lines and updates old ones. One checked, you can ckeck the "Auto correct load" checkbox.
By default, BODS will know a line already exists based uppon the primary key columns of your target table. If you want to change the columns used to determine if a line should be inserted or updated, use the "Use input key" checkbox (and define some PK column in your query).
Hope this helps

OSB JCA Merge operation for null value

I am doing a merge and when I supply the nodes the nodes I leave empty i.e. <somenode></somenode> I expect to update, if the record exists, the database to a null, but instead it does nothing and leaves the existing value.
Anybody know how to accomplish this, perhaps an attribute on the toplink file?

I figured it out. You have to change the DetectOmissions="false" in the wsdl where the merge operation properties are specified.

Using the match/merge operator

Hi guys,
I have created a simple table with 4 columns:
EMPLOYEES
- employee_id
- emp_firstname
- emp_lastname
- emp_telephone
I have placed 5 entries in the table:
11, jane, doe, 80980980
12, william, gates,6876876868
13, john, anderson, 545646546
14, michelle, millo, 340580334
15, john, anderson, 545646546
Row 13 and 15 are duplicates, except for the employee_id. I'm trying to use the match-merge operator to check for matches on emp_firstname, emp_lastname and emp_telephone. I would like to merge the rows matching on firstname, lastname and telephone number, and would like to keep the lowest employee_id as PK.
I have tried to use the match-merge operator with the following settings;
Input connections:
- employee_id
- emp_firstname
- emp_lastname
- emp_telephone
Merge output
- employee_id
- emp_firstname
- emp_lastname
- emp_telephone
Xref output
none
Match bins:
- emp_firstname
- emp_lastname
- emp_telephone
Match rules:
MA_0, all_match
Merge rules:
emp_firstname: all match
emp_lastname: all match
emp_telephone: all match
When I debug the match merge operator I get " 4 in, 4 out", but I expected to have "5 in, 4 out". Am I using this match/merge operator the right way?
thx for you help!

Hi Robert,
I tried on 3 database installations (all 10.2). there is no parameter DB_BLOCK_BUFFERS set. And i do not assume that there is a reasn for increasing the db_cache_size - means: why i did not get any error for that presumed case?
btw: can you explain why i should increase db_cache_size?
thanks,

Pl/sql procedure for match-merge operator

I have used the match-merge operator in OWB. I want to implement the same match-merge operation using a pl/sql procedure. Please help.

Yes sure. Lets say, we have a table tab1, which has the following structure and data:
First_name Last_name Address City
JACK ANDREWS XYZ NY
ANDREWS JACK NY
Now, i want to write a procedure which matches and merges the above two records, into a single record.The matching is done with the help of the first_name and last_name columns.

Multiple record upsert - Merge operation problem using DB Adapter

How do I make Merge operation into the target table case insensitive?

Hi All,
We have a target table that has a varchar 2 column called nat_key and a map that copies over data from a source table into the target table.
Based on wheteher the values in the nat_key column matches between the source and the target, an update or an insert has to be done into the target table.
Let us say target table T has the following row
nat_key
EQUIPMENT
Now, my source table has the same in a different case
nat_key
equipment
I want these rows to be merged .
In the OWB map, I have given the property of nat_key column in the target table as 'Match while updating' = 'Yes'. Is there a built in feature in OWB, using which I can make this match as case insensitive?
Basically, I want to make OWB generate my mapping code as
if UPPER(target. nat_key)=upper(source.nat_key) then update...else insert.
Note: There is a workaround with 'Alter Session set nls_sort=binary_ci and nls_comp=linguistic', but this involves calling a pre-mapping operator to set these session parameters.
Could anyone tell me if there is a simpler way?

Hi,
use an expression operator to get nat_key in upper case. Then use this value for the MERGE. Then nat_key will only be stored in upper case in your target table.
If you have historic data in the target table you have to update nat_key to upper case. This has to be done only once and is not necessary if you start with an empty target table.

Carsten.

Proc_getObject with nolock causes "read operation on a large object failed while sending data to the client"

SharePoint 2013 code for the SharePoint Config database stored procedure dbo.proc_getObject has been changed from SharePoint 2010 with the difference of select with nolock.
I am seeing numerous Error 7886, Severity-20 errors nightly:
"A read operation on a large object failed while sending data to the client. A common cause for this is if the application is running in READ UNCOMMITTED isolation level. This connection will be terminated."
Here I have commented out "with (nolock)" to 'fix' the error and to align the store proc with SharePoint 2010 code :
ALTER PROCEDURE [dbo].[proc_getObject]
@Id uniqueidentifier,
@RequestGuid uniqueidentifier = NULL OUTPUT
AS
SET NOCOUNT ON
SELECT
Id,
ParentId,
ClassId,
Name,
Status,
Version,
Properties
FROM
Objects --with (nolock)
WHERE
Id = @Id
RETURN 0
How is this stored procedure called and for what use?
Why did Microsoft make this change to SharePoint 2013 - some performance gain through dirty reads at the cost of stability? Or what could be a reason for this to happen that can be fixed?

GetObject retrieves any farm object that is selected (by ID). Changing this is obviously not supported, and NoLock was used to (help) prevent locks when performing a select query.
I've never seen this issue, and would guess it is unique to your environment given this is such a core piece of the SharePoint infrastructure.

Purchasing concerns while merging operating units

Hi all,
Can any body please guide regarding the concerned entities of Purchasing while merging two operating units?
Regards,
Abdul Rehman.

Hi Abdul,
While merging 2 OU, the following purchasing entities you should review as per opinion.
(1) Items of old OU should be created/assigened to merged OU, if it is not exists in merged OU.
(2) Similary , Suppliers of old OU should be created to merged OU, if it is not exists in merged OU.
(3) You should go for the redesign Posiition hierarchy and PO approval limit groups.
(4) New Payment terms should be require to create, if it is new for merged OU.
(5) Creation of new buyers are required.

Identifying old internal record id after merge operation

Hi,
Since a merge record operation creates a new record, with a new internal record id, is there a way to find the the old record id's that were merged into the new record? It would be ideal for us to have a method through the Java API's.
This is also particularly necessary for us to track change tracking through every merge. Is there a way to track change tracking for a record through all merges?
Thanks in advance.

Hi,
MDM provides Change Tracking functionality where you can track the changes like Record Addition, Modification and deletion. In case of Record Merging, it first delete the individual records to be merged and creats a new merged record. Hence you will find three entries in the Change Tracking if 2 records are involved in Merging process (depending on number of fields on which Change Tracking has been enabled).
You can view the Changes at database level by Quering the A2i_CM_History table.
Change Tracking in MDM
You can also make the Change Tracking UI available in the Web tab of MDM Data Manager

Merge Operating Units

Hi
Does anybody know how to Merge two operating units in EBS R12 ?
Thanks in Advance
Karbi

I believe this is possible - it is not a trivial exercise. You will need to engage a consulting organization (Oracle or third-party, which has done these kinds of merges before) to do this.

Merge-Operator

Hello,
I'm querying a WebService which returns a Collection of Foobar.
For each Foobar I want to query other WebServices and merge their results into the corresponding Foobar-Row.
Neither Union, nor Switch seem to be appropriate. I need something to merge the data from several ports.
Any hint how to implement this?
Thanks,
Kai

Hi Kai,
What you are describing looks similar to SQL Join functionality. There is no way to do this using Visual Composer operators.
You need to implement this in the Service layer (using CAF, EJB or any similar tool).
