Import SCA files in Development Tab of the Transport Studio take more time

Hi,
After Check-In files in the Transport Studio, the import of SCA files starts in the development Tab of the Transport Studio.
The import takes more time. Why this happens?
Am I missing any configuration? Please specify in detail.
Thanks in Advance,
Sathya

SC's Dependencies are missing in the check-In tab of the transport Studio

In SLD, the SC is created with the following dependencies:
(1) DI Build Tool 7.0
(2) SAP J2EE Engine 7.0
(3) SAP JAVA TECH SERVICES 7.0
Then, in NWDS, in the Development Configuration Window, the SC which is created is loaded.
Within the created SC, the DC is created. but the DC is created with some errors saying " The dependency files are not linked".

Please note the dependencies tag are empty.
I also done "update CMS". but still it remains the same. please explain me my mistake.
D:\usr\sap\JTrans\CMS\inbox folder is empty.
I could able to see all the buttons in the Check-In tab of the transport Studio. But the Check-In button is disabled and the table of Check-In tab is empty.
The required Track is selected in the left-hand side of the Transport Studio Window.
Please guide me.

Hi Sathya,
First you need to put SCA files
(1) DI Build Tool 7.0
(2) SAP J2EE Engine 7.0
(3) SAP JAVA TECH SERVICES 7.0
In your D:\usr\sap\JTrans\CMS\inbox in the server.
then you can create TRack and add SC dependancy to track...after that it will appear in the check-in tab.
Hope it helps,

Optimizing the query - which takes more time

Hi,
Am having a query which was returning the results pretty fast one week back but now the same query takes more time to respond, nothing much changed in the table data, what could be the problem. Am using IN in the where clause, whether that could be an issue? if so what is the best method of rewriting the query.

Why view have no stored data ? And what is the reason view take more time

Why view have no stored data ? And what is the reason view take more time to query ?
what happen if a view have stored data?

user12941450 wrote:
I want to know the reason that why querying view is slower then querying a normal table?..Untrue.
For example take a table with 2laks record and a view for that table.
If i make a query like( Select name,address from table) then it works fast then select(name,address)from view..Incorrectly interpreting the results.
A view is a SQL statement. Only difference is that the SQL statement is stored in the database's dictionary. Let's consider the following view:
create or replace view foo_view as select * from empWhen you use the view as follows:
select * from foo_viewOracle sees it as follows:
select * from (select * from emp)This is no slower, or no faster, than providing the following SQL to Oracle:
select * from empSo if you observe a difference in performance between using plain SQL versus using that same SQL via a view, there are other reasons for that difference in performance. The reason is NOT that views are slower.

Error while importing ESS.sca file in Development tab.

Hi,
we are importing the ESS.sca file development tab. we are getting the below error.
Fatal   Exception:com.sap.cms.tcs.interfaces.exceptions.TCSCommunicationException: communication error: VcmFailureException received: HTTP protocol error [cause: Parsing of the response body failed [reason: XMLParser: > expected to close empty element (:main:, row:1, col:3541811)]]:

srinivas,

Hi Srinivas,
Try this out. I had a similar problem and i did this to make the import successful.
1)     Go to usr/sap/J2E/JTrans/archives and copy the sca file with version shown like the above screen shot.
2)     Unzip the entire sca file by renaming it. In the META-INF folder open the SAP_MANIFEST.MF file and the replace the 32 character guid for the field 'pr_dtrwspropagationlistid'
3)     Change it to a different value and save it.
4)     There will be four folders when the sca file was unzipped. Select all the 4 folders and then zip it again to the original name of the sca file.
5)     Copy this file and then place it in the path usr/sap/J2E/JTrans/archives.
6)     Now try re-importing the file it should work.
Hope this helps,
Regards,
Nagarajan.

[JavaWebStart] the method showDocument take more time withJWS 1.6 ?

Hi,
I'm facing currently a problem since our product was migrated to Java webstart 1.6. Indeed, this problem is the same with JRE 1.5 or 1.6, it only depends of the JavaWebstart version.
We use the method showDocument of BasicService (http://java.sun.com/j2se/1.5.0/docs/guide/javaws/jnlp/javax/jnlp/BasicService.html)
BasicService bs = (BasicService) ServiceManager.lookup("javax.jnlp.BasicService");
bs.showDocument(file); This service is managed by JavaWebstart, that's why I have the problem independantly of the JRE version, it is only related to JavaWebstart version.
Since JWS 1.6, opening a documents takes 9 seconds when calling showDocument (it was only 1ms in JWS 1.5)
Does anybody already have this problem ?

Importing sca into local development

Hi,
I need to create a web dynpro DC in my local development workspace. It is not connected to any track.
I also want to use a DC from the LM-TOOLS.sca. How do I import this in my local develpoment file system. The only sca's that are present are th SAP-JEE, SAP_BUILDT, and SAP_JTECHS.
On a track I know I can import it in the transport studio.
But how do I import it on a local develpoment tree.
thanks

Error importing *.SCA file into NWDS: Import (into source SC) not possible

All,
When attempting to import an SCA into a new project in NWDS, an "Import (into source SC) not possible: SCA doesn't contain DC sources" occurs. Any assistance to fix this issue appreciated.
Thanks,
Lee

You can indeed import SCAs into local development configurations in NWDS (Eclipse). You have to have a pre-existing software component of the same name and vendor which may or may not be empty.
In the Development Infrastructure perspective in NWDS 7.1, just right-click on the software component you want to overwrite with the import and choose "Import".
To import SCAs into a CMS track in the NWDI, you have to go to http://<NWDI server>:5<nn instance no>00/devinf/ and import the SCAs from the transport inbox directory of the NWDI server. Don't forget to maintain the SLD if necessary.
Cheers,
Thorsten

Hi,
My problem is that: I created a Serializable class in a project. And I added this project (first project) to another project (second project). First project is appearing in the second project' s Libraries folder. No problem. I want to create a jar file from second project. i.e. I want to Build second project (I use NetBeans IDE). I am using Build Main Project tab under Run. It is falling out. I am finding it second project' s jar file under its folder. I am clicking on it. But it is NOT WORKING. Do you know WHY. Could you help me please?

Can we send more than 50 files ...even at the cost of a more expensive subscription level?

Can we send more than 50 files ...even at the cost of a more expensive subscription level?
Thanks.

Hi Val,
Nice to see you in the forums again!
There is currently just the one subscription level for Adobe Send. If you want to send more than 50 files per transaction, you can try zipping up some or all of the files and sending them in batches. However, the ZIP files can't be previewed by your recipients, and tracking information pertains only to the full ZIP file.
Best,
Sara

Lenovo have to call their customer number too, and the Solectron people like to put them on hold. Only when a Lenovo Executive gets involved like Mark_Lenovo can any problem with Solectron get resolved, as normal worker wouldn't have special contact numbers within the Solectron's management. So Lenovo call center workers get as frustrated as you if not more, as they hear complaints after complaints about them been thick and incompetent regarding depot repairs, when there is nothing more they can do, but obviously customers don't know the full story.

Multithreaded File Copy takes more time 1.5 times than single thread.
Is there any issue with this code. Please help me.

If all of your threads are doing CPU-intensive work, or all are doing I/O to the same interface (for example, writing to the same physical disk), then multithreading would not be expected to help you.
Multithreading does not magically make your CPU able to do more work per unit time than it could otherwise.
Multithreading does not magically make your network interface or disk controller able to pump more bytes through than it could otherwise.
Where multithreading helps (some or all of this has already been mentioned):
* When you have multiple, independent CPU-bound tasks AND multiple CPUs available on which to execute them.
* When you have tasks that involve a mix of CPU-bound and I/O-bound work. The CPU-bound stuff can crank while the I/O-bound stuff waits for bytes to be written or read, thus making use of what would otherwise be CPU "dead time."
What you're doing does not fit either of those scenarios. Copying a file is pure I/O. If the source and destination file are on the same phsyical disk or controller, adding threads only adds overhead with no real possibility to do more work per unit time.
If your source and destination are on different disks or controllers, then it's possible that you could get some benefit from multithreading. While one thread is waiting for bytes to be written to the target disk, the other thread can be reading from the source disk.

The 0co_om_opa_6 ip in the process chains takes long time to run

Hi experts,
The 0co_om_opa_6 ip in the process chains takes long time to run around 5 hours in production
I have checked the note 382329,
-> where the indexes 1 and 4 are active
-> index 4 was not "Index does not exist in database system ORACLE"- i have assgined to " Indexes on all database systems and ran the delta load in development system, but guess there are not much data in dev it took 2-1/2 hrs to run as it was taking earlier. so didnt find much differnce in performance.
As per the note Note 549552 - CO line item extractors: performance, i have checked in the table BWOM_SETTINGS these are the settings that are there in the ECC system.
-> OLTPSOURCE - is blank
   PARAM_NAME - OBJSELSIZE
   PARAM_VALUE- is blank
-> OLTPSOURCE - is blank
   PARAM_NAME - NOTSSELECT
   PARAM_VALUE- is blank
-> OLTPSOURCE- 0CO_OM_OPA_6
   PARAM_NAME - NOBLOCKING
   PARAM_VALUE- is blank.
Could you please check if any other settings needs to be done .
Also for the IP there is selction criteris for FISCALYEAR/PERIOD from 2004-2099, also an inti is done for the same period as a result it becoming difficult for me to load for a single year.
Please suggest.

The problem was the index 4 was not active in the database level..it was recommended by the SAP team to activate it in se14..however while doing so we face few issues se14 is a very sensitive transaction should be handled carefully ... it should be activate not created.
The OBJSELSIZE in the table BWOM_SETTINGS has to be Marked 'X' to improve the quality as well as the indexe 4 should be activate at the abap level i.e in the table COEP -> INDEXES-> INDEX 4 -> Select the u201Cindex on all database systemu201D in place of u201CNo database indexu201D, once it is activated in the table abap level you can activate the same indexes in the database level.
Be very carefull while you execute it in se14 best is to use db02 to do the same , basis tend to make less mistake there.
Thanks Hope this helps ..
