Newbie - concept question

I'm reading a lot about this topic everyday..but still not getting a clear picture.
I have heavy RDBMS and Data Warehousing background....lot to do with Oracle data management and reporting. Can this new technology (Semantic Web ) be applied in financial backoffice apps for integrated reporting without replicating the data (i.e without having a data warehouse environment ) ? Has anyone done it ?
Appreciate any pointers...
Thank you

The Apache web server itself does not support servlets / JSPs. You can use Tomcat (also part of the Jakarta project) with Apache or standalone.
There are several ways for an applet to communicate with a server. RMI is one approach but many people use HTTP requests that "talk" to servlets or JSPs. Basically, you open a URL connection in the applet and submit requests just like a browser would. Either servlets or JSPs could provide the server-side function, but if you're not looking for formatted HTML in the response, a servlet is probably the best way to go.

General place for newbie datamodeler questions?

With the production release of SQL Developer Data Modeler I'd assume that this forum will draw a bunch of new users. Is there a better place to ask some pretty simple, newbie like questions that won't bother the more seasoned members?
For instance, I am working in a Rails environment, which has some stringent naming conventions, one of which is that all of the primary key columns are numeric and called "id", with the foreign key linked columns called <table_name>_id. When engineering a logical model to a relational model, the added foreign key columns are all "id#". Is there a way I can define a naming rule to keep me from having to redo the relation column names?
Also, we have a standard set of columns (mostly Rails related) which appear in every table. Can I define a generation rule which automatically includes these tables?
Thanks

Thank you. I will try changing that setting.
IS there a setting which tells the relational model to automatically create pk and fk indexes? I haven't seen one, and manually setting them up is a tedious task. --sw

Concept Question about EDI and Error Processing

Hello All,
This is a concept question, I was wondering how others would approach this scenario.
Let's take this scenario. In EDI often the transmission for a purchase order comes in with an invalid material number. Normal error processing is for the EDI team to research the issue (find the correct matnr), edit the idoc and reprocess the Idoc. I would like to move that type of error processing out of the hands of the EDI folks and into the hands of the business users.
How would they correct the material number? It has to be more intuitive than editing an IDoc, it has to be an easy and intuitive user interface. This process has to also work for many types of EDI transmissions both inbound and outbound.
There would be many ways to handle this: create a report with an editable grid that would change the idoc during input and create the order with the corrections, convert the idoc to xml and use simple transformations, use an xsl report...etc. You get the point.
How would you approach this? Before I start the design I want to make sure I've given all the options due consideration...all options, webdynpro, transformations, regex, you name it...all is available, except there is no XI.
Personally I'm leaning towards an editable grid and processing buttons that would post the idoc in background...but I do that type of thing all the time and I may be in a rut and neglecting better design options.
Thanks for your input,
Greg

Paul: So it runs the transaction silently in BDC format, until the error occurs, then opens up in dialogue to allow the user to change the invalid material, and then continue on with processing.
This works when the processing function module uses BDC. But even then I think this is possibly nice from user perspective, but a nightmare from auditing perspective. I.e. correct me if I'm wrong, but I'm pretty sure there's no log indicating that the user changed the material number. Thus for anybody comparing the IDoc contents against the posted document (including change history) there's no trail that shows this change. Of course you can assume that this is what must have happened, but I personally prefer if I can track in the system what happened and have proof for that.
Reddy:
<ol>
<li>it can be run daily basis, which should select all idocs which are in status 51 with message number (..related to wrong material number). report output should inlcude :idoc number-wrong mat no- space for new material to be entered by business against wrong 1. And there should be one button for RUN.</li>
<li>After RUN, the material number should be changed to new 1 in segments and idocs should be reprocessed.</li>
<li>repeat the run until business enter right mat num.</li>
</ol>
Design seems to limited to me (takes care only of one error message). Might work if that's the main pain point and this is the only one the user is dealing with. Otherwise I'd expect pretty soon they start complaining about having to use different tools for the possible errors. I'd keep the report more general, but allow this special form of processing only for a given error message (otherwise it's a normal re-process as triggered for example via BD87).
Also, I assume that when you talk of changing the IDoc you mean that you actually keep an original copy around (like SAP does when you edit an IDoc). Often this is required from an auditing perspective. I'm not sure why you wouldn't want to check the material number before trying to process the IDoc to avoid wasting system resources (but maybe I misunderstood the step).
Anyhow, in theory you could also achieve all of this via workflow. You can add custom columns to the work item overview in the inbox, only issue here is that it doesn't scale well (so issues with larger volumes).

Newbie script question... consecutive numbers with update.

complete newbie type question... this is also my first post. ( I am using CS3)
does anyone have a script which can make it so I can add numbers into the text consecutively.
for example, if this is my text "the big fat dog sat on the very wide mat, but was then displaced by a unfriendly cat."
and I wanted to place a number 1, number 2, 3, etc at points in the text so it read, "the big fat dog1 sat on the very wide mat2, but was then displaced by a unfriendly cat3." but later wanted to add another number and have later numbers update themselves, so the text then said, "the big fat dog1 sat on the very wide mat2, but was then displaced3 by a unfriendly cat.4".
by inserting the three, the previous three became four.
Has anyone got something which might be useful in this regard.
Many thanks
Steve

i wanted to avoid footnotes as they leave a bar at the bottom of each page.
i wanted a script to do something similar to footnotes but not much further.
does anyone have just a simple script that can do what I asked?

Java Usage Concept Questions

I have a java Command line running program. Which allow input/edit data of clients and store them into a Flat file. The problem is that i have to make a GUI, ( a thin web based client ) and using only HTML and Javascript.
The next step is the db should be frontended by servlet or JSP that interact with thin client to perform the database retrievals.
Now my concept Questions:
1. Is it possible to communicate to a Java Program using HTML and Javascript? If so, any exampler, pointers?
2. I was thinking of using HTML and Javascript to directly modify the Database. ( Since it is a flat file therefore nothing more than a txt file ) But isn't this side stepping the problem?
3. If i could modify the Flat file using HTML and Javascript only. Why would i need JSP and Servlets? And if i could do it with JSP and Servlets only why would i need the think client ( HTML bit )?
If all of above 3 are correct ( conceptialy ), what is the orginal command line java program for?
The last question is why i think i have the concept wrong. Please i am new to web programming so feel free to point out any error.

Hello,
You a little off on a few things. let me explain what each is used for to give you a better idea what each i used for.
HTML - Used to format data. Is static and can't do any File I/O and such
Javascript - Is usaually used for client side validation and some cool effects.
JSP - Is a scripting language that allows you to execute code on the server to create dynamic content and server side stuff like saving to a DB or a file
Servlets - Kinda like JSP but gives you more control over a few things. Usaually used for form processing and Servlet/Applet communication
for you application i would probably embed HTML/JavaScript for layout and validation into a JSP page for your display pages.. then build JSP pages to handle all you business logic and processing.

Newbie XSan question - authenticating a computer from XSan Admin

Hello - I have a very newbie XSan question!
I have 2 computers that connect to an XSan. 1 I am having no problems with. The other I am unable to connect with.
When I look in XSan Admin the 2nd computer (the one that is not working) is not authenticated.
So I click on it and choose Authenticate. I enter what I know is an Admin username and password for the computer I am attempting to connect. The dot next to the computers IP turns green with 3 dots in it and then it turns gray again. It just does not connect.
What is the problem?
Is it licensing?
Thanks
Taj

You need a different license ID for each machine, plus the admin machine. Do you have that?

This Newbie Has Questions

Hi there. I am a newbie to Apple. I purchased the iBook last month and of course, when the MacBook (which had the features I wanted) came out, I rushed out and got one and I'm very pleased with my purchase - but I have a few "newbie" questions:
1) Printing on a PC based Linksys seems to be a nightmare. I can't get anything printed on the shared HP 2600N and HP1012 printers. I literally have to disconnect them from the PC and plug the USB directly to my MacBook to print. It seems like there should be a better, easier and MacFriendly way of doing this - anyone have an easy solution?
2) I'm going to purchase Windows XP so I can run my windows programs on this computer. Does anyone have any pre-installation advice?
3) I have a blackberry device that worked fine with my iBook, but does not work with my MacBook - any suggestions or is there a software compatibility patch?
4) I transferred everything from my old Mac to my new Mac with no problem. How can I migrate my contacts from Entourage to the Address Book?
5) I notice that sometimes the MacBook "stalls" or doesn't work fast in some functions...is it just me - I expect the machine to jump quickly...but sometimes I get that annoying pinwheel when opening programs.
Thanks for your help!

The problem is probably a driver issue.

You may need to use a third-party driver such as the HPIJS drivers or the Gimp-Print drivers, but this is not the case with all printers.
2) I'm going to purchase Windows XP so I can run my
windows programs on this computer. Does anyone have
any pre-installation advice?
Ensure you get a full version (not an upgrade version) and it comes with XP SP2 already.
Do not install Boot Camp on a critical machine and make regular backups of your data, this is beta software and there are bugs and issues.

Some very "newbie" networking questions -- trying to get started

Hello all. Since this forum is so friendly for issues related to Arch, I thought I'd post my semi-arch related question.
I'm trying to create a network for my house, consisting of about 3 computers. I have a book reference, TCP/IP Network Administration from O'reilly, but I think I need a bit of a "kick-start" in order to get to a level in which I can comfortably understand the book (if that makes sense).
I've got internet access working by connecting to a router and having everything configured by DHCP (ie, in rc.conf, eth0="dhcp"). What's bothering me (and I don't even know if it should) is that the other computers on the physical network are not visible to me.
IE, when I try to connect to them with their host name, it doesn't recognise them. My understanding of that is that either I need to manually set the hostnames of the other computers on the network in /etc/hosts, or use something like a DNS server on one of the computers in the network in order to recognize the others.
My other doubt is that I think I've got a dynamic IP address (though it might be static, I'm not quite sure). Does that change things?
I don't expect you guys to completely run through me setting up the network (that's what the book is for!) but some basic advice on either my misconceptions (I'm sure I have plenty) or related in general to my situation would be awsome and highly appreciated. I'd also be happy to provide any additional info that would be helpful.
Thanks in advance.

My set up is simple.
I have a Linux router running on an old Pentium machine. It has two cards, one configured for the private network (with an address like 192.168.1.1) and the second card set up to take addresses from DHCP ( since that's how Rogers sends you the public address).
In that machine I run my firewall, SmoothWall (smoothwall.org) and have enabled NAT so the machines in the inside network can go to the Internet.
I have Samba set up in another machine to share files (that's an Arch system) with static IP, my daughter's machine (another Arch system), my system (obviously another Arch with static IP) and my wife's machine with Windows XP system (static IP too).
So, the key concept here are:
1. Use static IPs for the private network
2. Use DHCP for Rogers
3. Use NAT in your router so all the machines can go to the Internet but no one from the Internet can get to them.
Hope this helps.
R
p.s. feel free to contact me off the list if you need further details/help.
Aha! So, for example, the network 192.168.0.0 where mask is 255.255.255.0 is a private network set up by my router, right?
So the addresses in 192.168.0.0 never change, but the public IP address of the hosts do change?
Does that mean that if, for example, I have a host called 192.168.0.32 that its address never changes? Can I simply add that to all the other hosts' /etc/hosts file and it won't change?
All I was ever concerned about was allowing hosts in the network to contact each other via hostname. If that never changes then I'm all set.
BTW, thanks for your continuing help!

Newbie wireless question (slightly off-topic)

I didn't want to post this here as it's not entirely an Airport-specific question. I posted this to the iBook forums, but nobody there has answered so my apologies if this is not welcome here. (Any moderators can remove it if that's the case.)
I've been using computers extensively for over a decade, but I'm a total newbie to wifi. I just set up a wireless network in my house and would appreciate some advice/feedback.
My main concerns are whether or not my network is reasonably secure. I know there is no such thing as perfect security, but I don't know if what I've done is good enough or not.
I don't have an Airport base station, but I do have a D-Link Airplus G and an Airport card in my iBook. I have WEP set up on the router and I have enabled MAC filtering, listing only my desktop and my iBook, excluding all others from the network.
I'm fairly certain that nobody in my neighborhood is going to get into my machines this way or be able to sniff my network data stream, but am I right in assuming that nobody can "piggyback" on my Internet connection too? Presumably, if everyone but my own machines are MAC-filtered and kept out, then the Internet connection is also protected. Is that how it works?

WEP and MAC filtering are better than nothing, but you can do better. These are my suggestions:
1. Use WPA with a pre-shared key (PSK) and TKIP encryption on your Netgear router, along with an alphanumeric passphrase of at least eight characters not found in any dictionary. The equivalent setting on your Mac is "WPA Personal". Unlike WEP security (which an expert can crack in under half an hour), WPA security is currently unhackable by any practical means as long as you use a non-dictionary passphrase. One last point - WPA security requires all your wireless Macs to be running MacOS 10.3 or newer.
2. MAC filtering is (these days) essentially useless as a wireless security method. Using "packet sniffing" of traffic on your wireless network to find out what MAC addresses are used by computers on your network, and a PC that allows its MAC address to be cloned so that it is identical to the MAC address of one your own wireless computers (which is possible with most PC wireless network adapters) even an amateur hacker can defeat MAC address filtering in minutes.
By the way - I don't think your posted message here is off topic. In my opinion, the Airport discussion forums are the best place to post any questions related to usage of wireless networks. Questions of this nature are virtually never specific to any Mac model.

Concept question

Hello All and Happy Friday,
I have a quick question from a newbie. I am running my 11.1.0.7 db on a Redhat5 host in ARCHIVE LOG MODE. I have my archived redos going into two different
locations. u02/oradata/CUST/ and s/22/san/flash_recovery_area/CUST. My s22 is getting kind of full, as a matter of fact, DB control tell me its 85% full. I only have 34 days of archive redos in the folder. Can I take the last 20 days and just copy them into another mountpoint with out disturbing the DB operation? We are doing on-line RMAN backups every night.
Second Question: We enabled this db host approximately on Mar 1st. On Mar 1st, we told RMAN to do a full back (use as base of incremental) and since then, it's been doing incrimentals every night (approx 370mb per night). So with that said, i only have 1 full backup. I don't see any harm in offloading or copying the archive redos to tape or another location.
Appreciat your help..
Rob

RobYou can (should) use rman to back up the archive log files and perform housekeeping on them. Here's what I do:
run {
   backup incremental level 1 cumulative database tag='bkup_incr';
   backup archivelog all not backed up 2 times tag='bkup_arch';
   delete noprompt archivelog all backed up 2 times to device type disk;
run {
delete noprompt obsolete;
crosscheck backup;
delete noprompt expired backup;
crosscheck archivelog all;
delete noprompt expired archivelog all;
}This completely automates all backup and housekeeping of my archivelogs, even with multiple archive destinations.
Note the above is my daily incremental backup. I run that Mon-Sat. On Sun I run a script that is identical expcept the 'incremental level' is zero instead of one. You really should take a periodic full (incremental 0) backup. It will make recovery much easier. Remember, you have to keep all archivelogs (in place or in a backup) back to at least your most recent full backup.

Newbie saving question in Illustrator

I know this is a newbie question. I designed a logo in Illustrator. Is there a way to save just the logo for exporting into other applications (ie Pagemaker or Photoshop) without having the white artboard?
Thanks
Brad

I don't know Pagemaker but with Photoshop I simply select all, copy and then paste in Photoshop - transparency will be maintained. If you paste as a Smart Object you retain the ability to edit the Illustrator artwork in Illustrator and update the PS file.

Newbie Grid Questions - Windows 2008 v11gr2

Hi all
As stated I am completely new to Oracle and have managed to do an single instance install and am now attempting a Grid and then RAC install.
I have created 2 VMs and 5 disks. During the Grid install I stamped the disks so that they could be used for ASM and put them all in a disk group called Data. I selected External redundancy.
In the previous documentation I have seen that during the Grid install you select where to put your voting files and OCR files but this never happened for me, is this correct? Also how can I check I have clusterware installed correctly? The documentation says that the verification utility runs automatically and I think this happened as the Grid install completed successfully.
One concept I am having troubles with is if the clusterware is installed as part of Grid then why do we need RAC?
My questions are probably very general and cover a lot, but any help in the right direction would be appreciated.
Thanks

Hi,
In the previous documentation I have seen that during the Grid install you select where to put your voting files and OCR files but this never happened for me, is this correct?If you selected to Oracle ASM as the storage option for the OCR and voting disk files, then the Oracle Automatic Storage Management Configuration Assistant (ASMCA) configures Oracle ASM as part of the installation process.
If you did not select Oracle ASM as the storage option for the Oracle Clusterware files, then you must start ASMCA manually after installation to configure Oracle ASM.
There are two ways of storing the shared Oracle Clusterware files:
Oracle ASM: You can install Oracle Clusterware files (OCR and voting disks) in Oracle ASM disk groups.
OCFS for Windows: OCFS for Windows is the only other supported cluster file system that you can use to storage of Oracle Clusterware and Oracle RAC files on Microsoft Windows platforms.
Starting with Oracle Database 11g release 2 (11.2) and Oracle RAC 11g release 2 (11.2), using DBCA or OUI to store Oracle Clusterware or Oracle Database files on raw devices is not supported.
Also how can I check I have clusterware installed correctly? The documentation says that the verification utility runs automatically and I think this happened as the Grid install completed successfully.You can use Cluster Verification Utility.
The cluvfy stage -post crsinst command to check the specified nodes after installing Oracle Clusterware.
http://download.oracle.com/docs/cd/E11882_01/rac.112/e16794/cvu.htm
One concept I am having troubles with is if the clusterware is installed as part of Grid then why do we need RAC?I do not understand what you meant with GRID is grid infrastructure (software Oracle ) or grid computing (concept).
If is concept check this..

Newbie forms question

Hi,
I'm just experimenting with forms (in the development suite) and I have now created a data block with table data, got it running within a browser and was feeling quite pleased with myself.
I have now tried to do a similar thing with a stored procedure and I get the error message FRM-10764 no argument of type table or refcursor.
Now I've done some plsql so I know about ref cursors, I do not however know what a table object is, or more to the point how/why a pl/sql procedure would/could return a table object.
Can anyone explain this concept of how a procudure returns a table object and why is it that forms will not let me just display a single string or numeric response from a procedure?
thanks in advance,
Paul.

Ed,
I am newbie myself on Oracle but I think I can help you on this one. Do the following:
1) Create the buttonl;
2) Assign a WHEN_BUTTON_PRESSED trigger to that button;
3) Use the CALL_FORM built-in procedure to call the second form; (look for examples on the help / forms builder help topics, it's a pretty good source of code sample and examples)
Hope it works out.

Dumb newbie hardware question! :)

Hi folks,
I'm new to the world of the blackberry and am just about to take the plunge with an unlocked sim-free BB Bold to use in the UK on Vodafone. I have read about the software differences between BIS and BES and would be going for a BIS set-up. My dumb newbie question is does the hardware come in BES and BIS versions or not?
Many thanks in advance and feel free to mock my foolishness
Solved!
Go to Solution.

hello, about BIS and BES it's explained on the website but it's clear that if someone sums it up for you it will be easier...
so BES is a type of contract between a company and Blackberry. The company IT buy computers, put Blackberry servers, and buy a fleet of Blackberry Devices for the people in the company to use them and get email through the Blackberry servers.
BIS is a type of contract between a common person and a carrier. The consumer goes to the carrier, and buys a Blackberry device, and a BIS plan that will enable him/her to :
phone/sms/mms
receive emails that have been configured on the BIS site
do data things if you subscribe to (like browse the web)
You can buy a Blackberry from a carrier that has a deal with RIM (the company that sells Blackberries). Or you can buy a blackberry alone, and then go and contact a carrier that has a deal with RIM.
phone/sms/mms
receive emails that have been configured on the BIS site

NEWBIE SOA Question:Appl Development for SOA

This question may have been answered elsewhere; if so, my apologies.
As a newbie to SOA, I am trying to wrap my head around the question of how app. development for SOA differs from traditional models. For example, non-SOA environments there are few external considerations when coding a process,
but in SOA environments, I understand everything is a service.
Can someone provide a few code snippets as to how they would look in each environment?
I have read through several documents on SOA and have done the SOA tutorial, etc. but I have yet to see a side-by-side comparison of application code in SOA and non-SOA environments.
How would an architect plan the translation and mapping of business objectives and functional requirements into a technical solution for SOA, architecting the SOA solution ?
I would really appreciate any pointers (links to articles, etc.) in this direction. Thank you.
Gordon

Hello Gordon,
SOA (Service Oriented Architecture) - as the name indicates, it's design is based on services. SOA is another integration technique which is used for small scale integration. SOA is an approach to have software resources in an enterprise available and discoverable on network as well defined services. Each service would achieve a predefined business objective and perform discrete units of work. The services are independent and do not depend on the context or state of the other services. They work within distributed systems architecture.
Few links which may help you in understanding SOA and it's design patterns -
