DBAdapter Select Operation 사용시 Performance 문제
게시일: 2006. 12. 15 오후 3:19 댓글
질문이 있습니다.
polling을 사용할경우만 MaxRaiseSize 나 MaxTransactionSize, NumberOfThreads
등을 사용할수 있는건가요?
그냥 select operation을 사용한경우는 이렇게 Performance와 관련된 Parameter가
없는건지 알고 싶습니다... 그리고 그냥 select operation을 사용한경우는
어떻게 하나의 instance가 처리할수 있는 xml data의 갯수를 제한할수 있는건가요?
즉 DBActivationSpec 의 Parameter의 경우는
위의 Parameter가 포함되는데...
DBReadInteractionSpec의 Parameter의 경우는
없더군요...
select operation을 사용할경우 성능향상을 위한 조언을 듣고 싶습니다..
감사합니다...

일단 프로세스의 단위를 먼저 규정해야 할 것 같습니다.
Polling을 한다는 얘기는 정해진 시간에 따라 주기적으로 프로세스를 실행하면서 해당 프로세스에서 처리하는 XML Message의 크기를 규정하는 것이 맞습니다.
그래서 관련된 파라미터가 제공되는 것입니다.
하지만 시작된 프로세스내에 존재하는 Query의 결과가 여러 개의 프로세스에 의해 실행된다는 것은 프로세스 설계 자체의 개념과 맞지 않는 것 같습니다.
만약 원하는 시점에 쿼리에 의해 처리를 하되 SQL의 크기에 따라 여러 개의 프로세스로 나눠서 처리하고 싶다면 Batch 프로세스의 성격으로 디자인 되어야 할 것 같습니다.
아래와 같은 방법을 사용하면 어떨까요?
Process A : Stored Procedure #1(SP#1)을 실행하는 프로세스
SP #1 : Query된 XML Data를 정해진 Logic에 의해 사이즈를 분할하여 AQ에 enqueue.
Process B : AQ로 부터 dequeue하여 프로그램 실행.
위처럼 프로세스를 설계하신다면 작은 메시지를 여러 개의 Thread가 동시에 처리하는 결과가 되므로 성능도 향상되는 결과를 얻으실 수 있을 것입니다.
다만 메시지를 처리하는 쪽에서 메시지의 우선 순위가 필요하다든지 한다면 correlation이나 message header에 Message Order등을 정해서 처리하도록 프로그램을 작성하셔야 합니다.
참고로, DBReadInteractionSpec의 경우는 아래와 같은 파라미터들을 가지고 있습니다.
DescriptorName
Indirect reference to the root database table that is being queried
Wizard updates automatically. Do not modify this manually.
QueryName
Reference to the SELECT query inside the relational-to-XML mappings file
Wizard updates automatically. Do not modify this manually.
IsQueryByExample
Indicates if this query is a queryByExample or not Wizard updates automatically. Do not modify this manually. This parameter is needed for queryByExample only.
MappingsMetaDataURL
Reference to file containing relational-to-XML mappings (toplink_mappings.xml) Wizard updates automatically. Do not modify this manually.

Move Excel Formatting on Operations performance issue

Hi,
Firstly we have a 64bit Windows system running EPM version V11.1.2.1, patched to .102, and Excel 2010 32 bit.
Having applied patchset 13709867 on the .103 SV version the old problem we had where formatting was not maintained when a fixed format report was cascaded remained so, having seen that the 32bit version of SV v11.1.2.2 was backwards compatible we experimented to see if it would resolve the problem, which it didn't.
However, when the 'Use Excel Formatting' and 'Move Formatting on Operations' are selected, the performance is horrendous which makes me wonder if there is some sort with the Office product? It's V14.0.6112.5000 for info.
Does this ring bells with anyone?
Thanks
Steve

1st, no I haven't had any feedback, although I have seen it in operation on other systems without the performance issues we experienced, which made me wonder whether there was some 'setting' in Office that could affect it.
Secondly, the grid had one row in it, it can't get much smaller than that.
3rdly, I never said anything about 'Move formatting....' having an effect on cascades, thanks. I said we hoped that the patch might resolve the issue.
Lastly - the reason cascading doesn't work is that it actually does work. When a sheet is cascaded, it doesn't use the current sheet options, it uses the default sheet options, therefore, to successfully cascade a highly formatted smart view report, ensure that the default sheet options (set on the drop down by the OK button) are set as per the excel sheet you created. Not even Oracle Support could tell me that.

BPEL and DbAdapter

Hello,
I am using BPEL and DbAdapter to insert a row into a table. Say, TABLE A with (ID NUMBER, NAME VARCHAR2(20).
I would like to use "Perform an Operation on a Table" and use native sequencing for ID.
Is there a way to return the ID value within a single invoke to DbAdapter?
Thanks,
Edmund

You can request a copy of a complete tutorial that showcases the DB adapter executing a SQL Server stored procedure in a BPEL process.
[Link to internal Oracle Web Site removed. Contact product management if you'd like a copy of the tutorial.]
Ask for "Adapter Tutorial 31 Integration with MS SQL Server Stored Procedure using DB Adapter" which is a ZIP of a complete tutorial.
The ZIP contains a command-line script (.bat file) that can be used to generate the BPEL artifacts. It's fairly straightforward. Read the PDF first.

DBAdapter - Select Query with parameter

Newbie Question : I need to get data from database based on a value entered by the user. I have created a dbadapter with select operation and it accepts one parameter that is used in the where clause. My question is how do I pass the value entered in the form to the db adapter parameter to get the results.

Your human task should take the parameter you're passing into your DB adapter call as a part of its payload. So there should be an incoming and outgoing data association for your interactive activity (human task) passing that value. Then in your service call you should have an incoming data association that maps that parameter into the proper input parameter of the service call.

COOIS report: not able to select operations based on work centers

Hi All,
When accessing the COOIS report using operation listv& selecting the std profile.I need to get the operation perfomred on specific work center.
I enter the work center & plant code in the selection fields available in the "select at operarion level" & i get the all the work center.
Need to get list of operation performed at the entered work center.
The requirement is due to the reason that a order is performed in two or three production facilities & production guys needs to look at operation list for given work centers.
Regards
Vineet

Hi,
This one of the options we had explored, but it would be better if we can get the report by work center. The focus is to reduce the effort to get the report as there is need to get the same report for atleasr 8to 10 different group of work centers ( which are not in serial nos).
We would then need to put the work centers in the filters & save the layout.
Regards
Vineet

Narration is coming from the computer for every operation performed.

All of the sudden I am getting narration from the audio on every operation performed. I also have noticed things are being highlighted by a black thin lined rectangle. In addition in my apple menu Restart, Shutdown, and Logout all have been duplicated. Is this all related? How do I turn off the narration?
Any help will be much appreciated!
Thanks

Select List Performance Issue in Apex 3.1.2

Hi
It would of great help if you could suggest us for the following
We are facing some issues in Select List performance in Apex 3.1.2 version.
We have 6 select list and all have been cascaded i.e., values of each select list based on pervious list value.
Values in each select list are huge. Because of this, the performance is very slow.
It takes huge time to fetch the data based on other list values.
We cross verified in backend, the same query takes less time compared to the Application.
Any recommedation to fine tune this?
Thanks in advance
Vijay

if your select lists are very huge then it could be the browser that is causing the slow down.
try and create an example using a static HTML file containing a select list of the same size and you may find the same performance issue.
a quick way to create the test would be to save the source of your APEX page as a html file

As answered by Punnet, your Datasource SOALocalTxDataSource on weblogic console is in suspended state.
Login to weblogic console. go to datasources --> SOALocalTxDataSource -->Control Tab --> Click Resume and try again.

Problem while using SELECT Operation in DB Adapter

Hi,
I am trying to use the DB Adapter with SELECT operation on one of the tables in our database. The query looks some thing like,
SELECT ORDER_HEADER_ID, SHIPPING_GRP_ID, ATG_SHIPPING_GROUP_ID, SO_HEADER_ID, ORDER_NUMBER, SHIP_ITEM_ID FROM <TABLE_NAME> WHERE (<CNAME> = #orderID)
I have selected order_header_id as the primary key during the creation of my process. And the rest are selected as part of the query.
The problem that I having is that I am getting the same data for all the rows, the output is as follows
<root>
<XxacOrderStatusDetail>
<orderHeaderId>265</orderHeaderId>
<shippingGrpId>262</shippingGrpId>
<ShippingGroupId>sg832798</ShippingGroupId>
<soHeaderId>4016992</soHeaderId>
<orderNumber>82555268</orderNumber>
<ShipItemId>r421379</ShipItemId>
</XxacOrderStatusDetail>
<XxacOrderStatusDetail>
<orderHeaderId>265</orderHeaderId>
<shippingGrpId>262</shippingGrpId>
<ShippingGroupId>sg832798</ShippingGroupId>
<soHeaderId>4016992</soHeaderId>
<orderNumber>82555268</orderNumber>
<ShipItemId>r421379</ShipItemId>
</XxacOrderStatusDetail>
<XxacOrderStatusDetail>
<orderHeaderId>265</orderHeaderId>
<shippingGrpId>262</shippingGrpId>
<ShippingGroupId>sg832798</ShippingGroupId>
<soHeaderId>4016992</soHeaderId>
<orderNumber>82555268</orderNumber>
<ShipItemId>r421379</ShipItemId>
</XxacOrderStatusDetail>
</root>
For the output above the "ShipItemId" should return different values but it is returning the same for all the results that are returned. As in the first entry should have r421379 then r421380 and then r421381 for the last one.
When I try including the "ShipItemId" as a primary key I am able to get the correct value but my process will fault in case if there is a null value for the column.
I wanted to know if there is a way that I can resolve this problem?
JDeveloper Version: Build JDEVADF_11.1.1.6.0_GENERIC_111205.1733.6192.1
SOA Version is also 11.1.1.6.0
Database Driver(Selected during data source creation on WLS) : Oracle's Driver(Thin XA) for Instance connection
Can anyone please help me with this?
Thanks.

Hi,
You are in a catch 22 situation, it won't work without a proper primary key defined, and a primary key is not suppose to contain nulls...
This type of case is one of the reasons I always tend to prefer to have surrogate keys on the database... If you had a surrogate key defined your problem just wouldn't exist.
Some references bellow...

SELECT query performance : One big table Vs many small tables

Hello,
We are using BDB 11g with SQLITE support. I have a query about 'select' query performance when we have one huge table vs. multiple small tables.
Basically in our application, we need to run select query multiple times and today we have one huge table. Do you guys think breaking them into
multiple small tables will help ?
For test purposes we tried creating multiple tables but performance of 'select' query was more or less same. Would that be because all tables will map to only one database in backed with key/value pair and when we run lookup (select query) on small table or big table it wont make difference ?
Thanks.
