Need clarification J2EE vs J2SE

I did a search on this topic and things are becoming a bit more clearer, but I want to be sure. I have just finished taking an intermediate java course and I am ready to work on an email application and learn some web programming using java server pages. Java is my first object-oriented programming language and I have programmed web pages using active server pages specifically vbscript.
Right now I have J2SE 1.4.2 installed on my home computer. In order to build a the email app I need the JavaMail API( a separate download) and you also need the activation framework(a separate download) and for JSP I will need to download the JSP specification and then JSP will not run on IIS so I will need a separate web server. If I need anything else or I want to learn a new skill there will be a separate download again.
I believe all of this is included with J2EE but you have to have J2SE installed from what I have been reading. the J2EE full download includes the application server which I am not sure If I will need it. I read that you could install the Tomcat server to work with IIS or separately. I am not sure which way to go. I also wanted to download the java web services developer pack 1.3 because of the ANT build tool for deployment, JSP,Tomcat and XML. Is everything included in the java wsdp included in the J2EE?
i have a lot of questions. Can anyone clarify this for me?

The J2EE 1.4 SDK has the Sun Java System Application Server, J2EE 1.4 samples, and includes J2SE SDK. Java WSDP 1.3 also has JAXB and some extra Web services security features and the Tomcat Web container, but does not include J2SE SDK and contains non-final releases of JSTL 1.1 and JavaServer Faces 1.0.
If you already have J2SE 1.4.2 installed, you can just download the Sun Java System Application Server or Java WSDP 1.3. The J2EE download page has a diagram that shows what's in the J2EE 1.4 SDK:

J2EE or J2SE Install?

I'm trying to updating my JBuilder JDK but don't know which JDK to install?
Do I install the J2EE JDK or the J2SE JDK?
Does the J2EE JDK have access to all the classes that the J2SE JDK has?

So, you have J2EE SDK already installed, and you want to use another J2SE version that you installed separately, right?
To do that, you should update <j2EE_install_dir>/config/asenv.bat file. Variable AS_JAVA should point to new J2SE installation directory. Then, you also need to change the J2SE installation used by default server domain - easiest way to do that is to use admin console and follow instructions available here:

Need Clarification On Internal tables in Start Routine

Hi,
I have intenal table some IT_A which deletes the requests which are populated in to it.
Now I need to populate requests into IT_A from another internal table like IT_B which are of different structure.
I have three fields in common in both internal tables like RNR,Timestamp n SID with different field names
I Need Clarification that if i move the contents of the three fields to IT_A from IT_B by spcifying these three fields.Will the internal table IT_A deletes the Requests?
Thanks,
Sriram.

Hi Sriram,
As mentioned IT_A deleted the request loaded into it.
if you move the contents of the three fields to IT_A from IT_B by spcifying the three fields after the deletion step for internal table IT_A takes place then it wont get deleted.
But it would be deleted if the the contents are moved before the deletion step takes place

mahesh

Need clarification on issue with tablespaces

Hi All,
I needed clarification on this issue with tablespaces.I am following a guideline which says "Presently,The general rule of thumb is to concentrate on tablespaces that are 90% or greater used and have less than 2 GB of free space"
My Scenario:-Now i have tablesace which is 97.23 % and the free space is 10 gb.Please advise me that whats the best next step I can take in this respect?
I am very new to this and just following the guideline,so can you all please explain me some details about this.
Thanks

Well, the guideline says "*and* have less than 2 GB of free space"
Since that tablespace as 10GB of free space, the guideline says that you do not need to concentrate on it. Eh ?
I would be careful with guidelines that are hard-coded in this manner. You need to know the context in which the guideline was set.
Assuming that your database/application doesn't grow suddenly by 1GB or larger (or create temporary segments / objects of 1GB or larger), the "2 GB of free space" might make sense. Then, again, it depends on the extent allocation type. What size are extents getting allocated.
You should check with your organisation's senior DBAs on what happens if you don't concentrate on a tablespace because it is outside the guidelines !

Need clarification on Bigfile Tablespaces

In the following Oracle Documentation Lirbary PDF,
    Oracle® Database
    Concepts
    10g Release 2 (10.2)
    B14220-02
    October 2005
section
    Overview of Tablespaces
    Bigfile Tablespaces (page: 3-5)
it says,
    Benefits of Bigfile Tablespaces
    * Bigfile tablespaces can significantly increase the storage capacity of an Oracle database. Smallfile tablespaces can contain up to 1024 files, but bigfile tablespaces contain only one file that can be 1024 times larger than a smallfile tablespace. The total tablespace capacity is the same for smallfile tablespaces and bigfile tablespaces. However, because there is a limit of 64K database for each database, a database can contain 1024 times more bigfile tablespaces than smallfile tablespaces, so bigfile tablespaces increase the total database capacity by 3 orders of magnitude. In other words, 8 exabytes is the maximum size of the Oracle database when bigfile tablespaces are used with the maximum block size (32k).
I need clarification on how to arrive at 8 exabytes ?
1024 x 32k x 64,000 ??
According to the exerpt above, there's no mention of maximum number of Operating System blocks per extent. Unless this was assumed knowledge ... how do I get 8 exabytes ?
And if "a database can contain 1024 times more bigfile tablespaces than smallfile tablespaces", then what's the upper limit on smallfile tablespaces ? -- was this sentence referring to the number of datafiles per smallfile tablespace ? ...
O_o
Thanks !

Hi,
According to [url http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14237/limits002.htm#i287915]Physical Database Limits page, a bigfile tablespace contains only one datafile or tempfile, which can contain up to approximately 4 billion ( 232 ) blocks. The maximum size of the single datafile or tempfile is 128 terabytes (TB) for a tablespace with 32K blocks and 32TB for a tablespace with 8K blocks. In resume, A bigfile tablespace is a tablespace containing a single datafile that can be as large as 128 terabytes (TB), depending on the block size of the tablespace. In conjunction with setting the initialization parameter DB_FILES to the maximum value of 65,635 the total size of the database can be more than 8 exabytes (EB)
>>how do I get 8 exabytes ?
You can calculate the maximum amount of space (M) in a single Oracle database as the maximum number of datafiles (D) multiplied by the maximum number of blocks per datafile (F) multiplied by the tablespace block size (B):
M = D * F * B. Therefore, the maximum database size, given the maximum block size and the maximum number of datafiles, is:
65,535 datafiles * 4,294,967,296 blocks per datafile * 32,768 block size = 9,223,231,299,366,420,480 = 8EB.Cheers

BPM, Workflow and Netweaver - Need Clarification

Hi Guru,
I am new to workflow, BPM and Netweaver. I have several questions about those concepts.
1. What is/are the different between workflow and webflow. Which scenario should take workflow into consideration? Which scenario webflow can be applied to?
2. What is/are the different between workflow and BPM. If I am going to implement workflow in a company, do I need to implement business workflow as well as BPM?
3. I need clarification on Netweaver platform and concept.
4. What is/are the different between workflow in R/3 and workflow under Netweaver?
5. If I am going to implement workflow integrated with R/3 and Outlook email, do I need to buy new wrokflow for Netweaver and Netweaver platform or alternatively, I can use business workflow module under R/3 system?
Sorry for many questions asked. I am new to those products. I am now working on software selection for workflow technology. My company is going to implement new workflow to client. Thank you very much.
Cheers,

Please ask only one (or closely related) questions per thread. This makes it a lot easier to get a good structure in the database of previously answered questions. While we are on the subject of previously answered questions, I think you should have a look at them....
My suggestion is therefore:
1. Close this thread
2. Read the Frequently Answered Questions. Before you ask (here are many workflow answers)
3. Search the forum.
4. Create new threads if you have questions afterwards.

Need clarification for these names, R/3, WAS, NetWeaver

I posted the question on WAS preview installation, then I realized I should have put it here. Here is the link to that post:
Need clarification for these names, R/3, WAS, NetWeaver

Hi Xueqing,
First of all, sorry for any confusion that we have caused you. I hope I can give you an answer that will clear up the confusion. Sorry, but it is a long explanation of the development of two application solution but history tends to be very long winded!
It is not true SAP R/3 Enterprise equals SAP Web AS, and I'll hopefully explain why:
In the beginning (at least in the client server world) SAP only ship SAP R/3. The technology layer under SAP R/3 was called SAP Basis. There was only SAP Basis under SAP R/3.
SAP then started to deliver other software solutions that were not included in or built on the SAP R/3 software. These included SAP Business Information Warehouse, SAP APO, SAP SEM, SAP CRM, and the list goes on.
These solutions needed to run on technology layer (like SAP R/3 did). SAP Basis was the obvious choice for this because of the common technology layer providing DB/OS abstraction and a coding environment.
~2001:
Later there came the need to have SAP Basis support the web and its web standards and other programming languages. This radically changed what SAP Basis was and we decided to rename the new technology layer to SAP Web Application Server (SAP Web AS). So the SAP Basis name was retired and SAP Basis 4.6D was the last release called SAP Basis.
The new release and the "technology change" means that all the applications mentioned above now ran on SAP Web AS. The first release of SAP Web AS was 6.10.
~2002:
SAP Web AS was first used in SAP R/3 Enterprise release .
The important fact is that SAP R/3 Enterprise runs on SAP Web AS. SAP R/3 Enterprise = SAP R/3 business applications + new business functions + SAP Web AS.
~2003:
I hope the above explanation is clear, because technology takes another major change. It was realized that SAP now had a collection of business solutions/applications (SAP R/3, mySAP CRM, mySAP SCM, etc) and a collection of technology solutions (SAP Web AS, SAP BW, SAP EP, etc). The technology requirements for the business solutions did not end at SAP Web AS, they needed portal, data warehouse, knowledge management capabilities, etc to develop business solutions on.
To address this SAP made the decision to combine all the technology solutions and tools into one single platform. This made complete sense for developers (SAP, Partners and customers). This single platform is called SAP NetWeaver. It includes all the old individual components of SAP Web AS, SAP BW, SAP KM, SAP EP, etc).
~2004:
I think you can guess what the next step is. Yes, the new release of SAP R/3. Since the release of SAP R/3 Enterprise and the release of SAP NetWeaver, SAP R/3's name changes. It is now called mySAP ERP as it includes a lot of applications that were previously sold separately (like SAP SEM, MSS, ESS, etc).
So now mySAP ERP runs on SAP NetWeaver (yes everything that was in SAP Basis and then in SAP Web AS is still there but SAP NetWeaver has so much more now).
Also with the release of SAP NetWeaver, SAP starts to stop using the old technology component names - you will not hear us talk about SAP Web AS, SAP BW, etc anymore, just SAP NetWeaver releases.
In addition all the other SAP business applications also run on SAP NetWeaver, so the latest version of mySAP CRM, mySAP SRM, and mySAP SCM all run on SAP NetWeaver.
So to simplify the explanation, it would be :
Evolution of SAP R/3:
SAP R/3 (up to release 4.6c) -> SAP R/3 Enterprise (releases 1.00 through 2.00 -> mySAP ERP (2004 onward)
Evolution of Basis:
SAP Basis (up to release 4.6d) -> SAP Web AS (up to release 6.40 which was included in SAP NetWeaver '04) -> SAP NetWeaver (2004 onward)
SAP NetWeaver and mySAP ERP have their own release cycles. mySAP ERP always has an underlying technology release that it is built on (this is a SAP NetWeaver release)
I hope this helps,
Mike.

Need clarification regarding the test cable-diagnostics tdr command

Hello,
I've read about the test cable-diagnostics tdr command but I need clarification on the examples listed below to make sure that I am providing the right answer to my co-workers.
Example 1:
CXXX7SW17#show cable-diagnostic tdr int g0/20
TDR test last run on: July 16 10:23:00
Interface Speed Local pair Pair length        Remote pair Pair status
Gi0/20    auto Pair A     N/A                        N/A                Normal
                       Pair B     72   +/- 10 meters N/A                Open
                       Pair C     75   +/- 10 meters N/A                Short/Crosstalk
                       Pair D     74   +/- 10 meters N/A                Short/Crosstalk
Does this example mean that there's a cable length issue in the line which is causing the device that it's connected to not to work properly?
Example 2:
CXXX2SW140#show cable-diagnostics tdr int g0/21
TDR test last run on: July 16 09:16:22
Interface Speed Local pair Pair length        Remote pair Pair status
Gi0/21    100M Pair A     N/A                      Pair A           Normal
                          Pair B     N/A                      Pair B           Normal
                          Pair C     N/A                     Pair C           Normal
                          Pair D     N/A                     Pair D           Normal
Does this example state that the cable line is okay for use?
Example 3:
CXXX1SW19#show cable-diagnostics tdr int g0/22
TDR test last run on: July 16 06:36:53
Interface Speed Local pair Pair length            Remote pair Pair status
Gi0/22   auto    Pair A       1    +/- 10 meters N/A               Open
                          Pair B     39   +/- 10 meters   N/A               Open
                          Pair C     72   +/- 10 meters   N/A               Open
                          Pair D     1    +/- 10 meters    N/A              Open
Does this example mean that there isn't a device connected on the other end? No pin-contact?
Thank you very much for any help you could provide.

I found this article here at supportforums that seemed like the best explanation I've read so far for TDR info.
Hope that helps.

J2EE vs J2SE

I have J2SE installed in my PC. Now I am starting to learn EJB and I will install J2EE. Should I install J2EE over J2SE or should I install it on a different directory? Thanks.

I just installed the full J2EE on my server, for the EJB stuff etc.
J2EE contains J2SE! J2SE is the Java Development Kit (JDK), look in your j2ee installation directory
<je22_install_dir>/jdk
J2EE also contains its own ant and some kind of ant wrapper called asant.
If you just download the j2ee application server you will have to inform it of your current JAVA_HOME during the installation process, but if you do install the full j2ee it will install itself.
All I really had to do was change my JAVA_HOME environment variable, everything seems to be working fine.

J2EE and J2SE

Hi, I´m a new SAP Netweaver platform developer, and I need to learn how to use the J2SE client application connections (Jco) with R/3 system on my engine J2EE... Do I have to rebuild them? or Do I have to make a new application on JSP or APPLET?

Hi,
the question is, what you want to do with it. First of all it continues to run I suppose. Though, the question should be, what you cannot do with it, what you want to realize with NetWeaver. From there you get to the next steps.
Surely you can reuse your code in a new app - the question merely is why you want to rewrite.

ZCM 11 SP3 and Windows 8.1, need clarification...

I dont know if I can't read, but I need som clarification...
When SP3 arrived, there were problems with Win 8.1.
I have customers that have machines, that were upgraded to 8.1 and it have worked with the already installed 11.2.3a -agent, even if its not supported. They deployed ZCM 11.3-agent to this machines that were upgraded to 8.1, and they all crached, never started again. I made tests in my test-environment, same result.
Last week I started to check and found the update "ZENworks 11.3.0a Windows 8.1 Update" (https://www.novell.com/support/kb/doc.php?id=7014805 / http://download.novell.com/Download?...d=0yMdXrTonF8~). Downloaded that yesterday, and was to test it today. Looked for the instructions again today, and now its not availble anymore, Obsolete. I have not deplyed it yet, so that is no problem.
There are since yesterday a new update, "ZCM 11.3.0 WIN8.1 Patch 866736" (http://download.novell.com/Download?...d=OvBLs9qZhrU~).
But in the instructions on this, it talks about it talks about how to update machines already updated. Here the text mentions "11.3.0_WIN8.1". What is that? Is it the now Obsolete "ZENworks 11.3.0a Windows 8.1 Update"? Or machined patched with the standard "Update for ZENworks (11 SP3)", that was created during SP3 install? If reffering to the last, it cant be done because in both my customers production environment and my testenvironment the Win 8.1 machined crached and never came up.
Next two methods in the description describes how to update "Windows 8.1 Update for ZENworks (11 SP3)", if already imported (zman supf "Windows 8.1 Update for ZENworks (11 SP3)" ZCM_11.3.0_WIN8.1_20140404_866736.zip).
But for those who have not imported that, what is the way to go? You cant download "Windows 8.1 Update for ZENworks (11 SP3)" anymore, and the patch seems to be for that one?
What is the way to get Win 8.1 to works with ZCM 11.3?
Can anyone clarify this?
I dont know if this belongs in agent forum or server-forum, but I start here.

Download of latest J2EE and J2SE

I am new to the technology, tried downloading the software from the site, but due to slow connection I am not able to download the package, I also tried using download accelerator and sun download manager but all in vain. If someone can help me to find if I can order the CD-ROM for the same I do not need the licensed software, I need it for test and not for production. As far as I know it is freely downloadable. But CD, if somebody will let me know how much will that cost? And if directly sun people can help me in getting this CD.
Thanks for looking into my problem..

As for J2EE installation - if I understood correctly this is Windows ME and you'll need to take a look at
this in order to get installer to run:

B2B Inbound Error : Need Clarification

Hi All,
I would like to illustrate a particular use case for B2B Inbound Errors and if there is any workaround available to get over the problem. We are using B2B version 10.1.2
Use Case Details</strong1. Consider the scenario wherein we have a Inbound EDI File which has 100 transactions in it. B2B reads the file and automatically debatches into individual transactions and processes them separately.
2. Out of the 100 transactions in the input file, if say 5 transactions are error transactions, we have observed that all the 100 transactions error out in B2B.
3. The 95 correct transactions fail with the error "General Validation Error" and the 5 error transactions have the exact error details in the B2B Message Reports.
4. Ideally, B2B should error out only the 5 error transactions and process rest of the 95 transactions without allowing them to fail with "General Validation Error".
I am sure that most of us must have faced this error. Could someone please let me know the folllowing:
1. Is there any setting in B2B by which we can enable it to error out only the transactions which have valid errors in a single file
2. Is there any other workaround that we can take to avoid this issue.
The reason we need to have a solution for this is because in our Production B2B environment we receive inbound files from Trading Partners which have hundreds of transactions in each file.
If, even a single transaction has error, then the whole file errors out and it is quite cumbersome to browse through the B2B Message Reports to get the exact error transaction because all the correct transactions would failed with error "General Validation Error".
Please let me know the inputs.
Thanks,
Dibya

Hi Ramesh,
Thanks for the clarification and information. We have already set the parameter OneErrorAllError = true and my understanding was that if we set this parameter to TRUE, it means that if one transaction in the OUTBOUND batch errors out then the whole batch will error out.
I was not aware that it also holds true for INBOUND. Is there any other way that we can set this parameter based on direction (INBOUND or OUTBOUND).
We would like to have this parameter set for OUTBOUND and disabled for INBOUND Transactions.
Please let me know. Thanks Again.
Regards,
Dibya

Need clarification regarding select query

Hi,
I need a little clarification regrding a Select senario
I want to select data from table which have been minupulated between a certian date like between 1-DEC-10 to 31-DEC-10 and note that table does not have any time/date column. I've applied the following query to do this.
select * from TABLE_NAME where sysdate between to_date('01-DEC-10') AND to_date('31-DEC-10');
Would it work fine because I've tried it against a table and it returned me nothing however DML occur between time period.

Unchecking Print Resolution - need clarification, need Jeff Schewe

Seeking clarification on using the print module in LR. Have read several threads in which Jeff Schewe (Jeff, are you there?)suggests that you use your file as a master file in LR and that if you uncheck the print resolution box, you can print multiple sizes of an image by merely changing the print size in LR, provided you uncheck the print resolution box.
Want to make sure that I've got this workflow right. You do your edits in LR and process your raw file. Then bring the file into CS3 for whatever other tweaks are needed. Add a layer and do your output sharpening on this layer, but don't go up to the Image, Image Size command. Do your sharpening without resizing or resampling.
My RAW files come into CS3 with a resolution of 240 pixels/inch. This is the native resolution?? After sharpening in CS3 (without resizing or resampling), bring the file back into LR. In the print module, uncheck print resolution (LR shows the resolution as being 240 ppi)and enter the height and width of the print size (not the paper size, but the print size) in the cell size. Go into page setup (Windows) which will take you into your print driver. On my Epson r2400 this is where I choose sheet vs roll, paper type, print quality, click ICM, then click off. Ok my way out of the Epson driver back to LR. On the white page layout in the center of the print module, LR will give me a new ppi reading. In my workflow, I typically print at 8x12 inches, so now LR is telling me that it is at 275 ppi. Pick profile and rendering intent in color management. As long as the read out for my print size in the white center section of lightroom reads between 180-480ppi, then at this point I am good to go and click print.
Have I got it? Am I missing something? Please, enlighten me.
Will LR provide a superior print to CS3 or is it six of one, half dozen of the other?
Thanks,
Cynthia

First off, it's poor form to address posts in a public forum to single individuals...this is a forum and ALL members should be encouraged to post...this is akin to asking for an answer to a question be sent directly by email.
The resolution of raw files is xxxxpixels by xxxxpixels. That's the only way to think of resolution in Lightroom. As a result, the image may be said to be 240, 300, 360 or 480 PPI depending on the size the image will print. A small print, held closer will need more PPI than a large print hung on a wall. So the resolution of a raw file will vary depending on the size of the final cropped & printed image. As long as the PPI of the image size is between 180-480 PPI you really have no reason for up or down sampling...
When I work on an image in Photoshop from Lightroom, I'll have an image print size in mind. I use softproofing for final tweaks to the image-often applied locally and set the PPI (Image Size without resample) to the size I want then use PhotoKit Sharpener for the resulting pixel density. Then hit save and print from Lightroom.
The -Edit file in Lightroom has the pixel density I speced in Photoshop and the softproofing tweaks as well. I then print form Lightroom-not so much because Lightroom is capable of producing BETTER prints...but because I find it quicker and easier to print with LR's print environment.
If I want to make a different sized print (or a print on different papaer requiring a different profile) I'll open the tiff image into Photoshop from Lightroom using the Edit Original...my original tiff file with all layers pops open, I'll make whatever changes I need and hit save again...so that one master tiff file becomes my print mater file with all the layers I may need to either use, or turn off if I don't need them. The same image, if printed 4x6 will have different pixel density than a 13x19" print, thus I'll have tow separat sets of output shaprening. But I don't need to resample the image, I resize without resampling checked to change the ratio and density.
And yes, all of this with Lightroom's print module set to no resampling and no sharpening...minor changes in the image cell size in LR don't require going back into Photoshop for resizing...

Need clarification J2EE vs J2SE
