Basic design questions

I want to design an icon for an Android app in CS5, and there are lots of design guidelines that need to be followed, and there are a couple I am unclear of:
1.) they have to be caricatural in nature - how would you interpret this? what does this mean?
2.) with very little perspective - how would you interpret this? does this mean they need to be close to flat?
Sorry, English is not my first language.
Thanks for your input.

wb,
Caricaturial means that they should create a certain impression by enhancing certain features instead of being a natural/neutral photographlike appearance, likes caricatures/cartoons/mangas/satirical drawings.
Very little perspective does mean close to flat, once again a simplified representation instead of natural/neutral photographlike.

Basic Design Question - Firewall Router segment

I'm at a new place and have to re-do the current lan. Small office, 80-100 users. Existing setup is flat network, no QoS, no VLANs. I have already replaced an older PIX with a new ASA (5525x) and added a DMZ.
I am currently trying to draw up a proposed design which currently will be single firewall, multiple VLans(user, server, voice, guest). My question is regarding the link between core router(L3 switch, whatever) and firewall.   I'm thinking the correct setup is to have a seperate /30 subnet on the interfaces between the firewall and router as below, and then router will just have a default route of 0.0.0.0 0.0.0.0 10.1.100.2     Is this correct?
Internet-------Firewall-(10.1.100.2/30)----------------------------(10.1.100.1/30) --Router ----(10.1.1.1/24, 10.1.2.1/24, 10.1.3.1/24, etc)
Thanks,

Your design is good. But as for the subnet between the core (router or L3 switch - switch preffered) and edge FW, i suggest something a little larger than a /30. Like a /28. You may want to add a standby FW in a few months or years, or a new WAN connection to that 'demarc' subnet' at some point. It's good practice to leave some romo for growth. Even if you dont forsee it right now.

Very basic design question of File Adapter

Hi Guys,
What is the utility of assigning System Name and System Interface names (XMB.SenderInterfaceNamespace, XMB.SenderInterfaceName, XMB.SenderBusinessName) while configuring the Inbound File Adapter?
What I am struggling to understand, that any particular inbound file adapter is already associated with one particular Sender Agreement and the message header picks up Sender System Name and Sender Interface name etc from this Sender Agreement (from CPA Cache), but then why the above settings are required for File Adapter ?
Thanks

I think you have read the documentation for J2SE adapter.
The online help for the J2EE adapter is here:

Design question: Scheduling a Variable-timeslot Resource

I originally posted this in general java programming, because this seemed like a more high-level design descussion. But now I see some class design questions. Please excuse me if this thread does not belong here (this is my first time using the forum, save answering a couple questions).
Forum,
I am having trouble determining a data structure and applicable algorithm (actually, even more general than the data structure -- the general design to use) for holding a modifiable (but more heavily read/queried than updated), variable-timeslot schedule for a given resource. Here's the situation:
Let's, for explanation purposes, say we're scheduling a school. The school has many resources. A resource is anything that can be reserved for a given event: classroom, gym, basketball, teacher, janitor, etc.
Ok, so maybe the school deal isn't the best example. Let's assume, for the sake of explanation, that classes can be any amount of time in length: 50 minutes, 127 minutes, 4 hours, 3 seconds, etc.
Now, the school has a base operation schedule, e.g. they're open from 8am to 5pm MTWRF and 10am to 2pm on saturday and sunday. Events in the school can only occur during these times, obviously.
Then, each resource has its own base operation schedule, e.g. the gym is open from noon to 5pm MTWRF and noon to 2pm on sat. and sun. The default base operation schedule for any resource is the school which "owns" the resource.
But then there are exceptions to the base operation schedule. The school (and therefore all its resources) are closed on holidays. The gym is closed on the third friday of every month for maintenance, or something like that. There are also exceptions to the available schedule due to reservations. I've implemented reservations as exceptions with a different status code to simplify things a little bit: because the basic idea is that an exception is either an addition to or removal from the scheduleable times of that resource. Each exception (reservation, closed for maintenance, etc) can be an (effectively) unrestricted amount of time.
Ok, enough set up. Somehow I need to be able to "flatten" all this information into a schedule that I can display to the user, query against, and update.
The issue is complicated more by recurring events, but I think I have that handled already and can make a recurring event be transparent from the application point of view. I just need to figure out how to represent this.
This is my current idea, and I don't like it at all:
A TimeSlot object, holding a beginning date and ending date. A data structure that holds list of TimeSlot objects in order by date. I'd probably also hold an index of some sort that maps some constant span of time to a general area in the data structure where times around there can be found, so I avoid O(n) time searching for a given time to find whether or not it is open.
I don't like this idea, because it requires me to call getBeginningDate() and getEndDate() for every single time slot I search.
Anyone have any ideas?

If I am correct, your requirement is to display a schedule, showing the occupancy of a resource (open/closed/used/free and other kind of information) on a time line.
I do not say that your design is incorrect. What I state below is strictly my views and should be treated that way.
I would not go by time-slot, instead, I would go by resource, for instance the gym, the class rooms (identified accordingly), the swimming pool etc. are all resources. Therefore (for the requirements you have specified), I would create a class, lets say "Resource" to represent all the resources. I would recommend two attributes at this stage ("name" & "identifier").
The primary attribute of interest in this case would be a date (starting at 00:00hrs and ending at 24:00hrs.), a span of 24hrs broken to the smallest unit of a minute (seconds really are not very practical here).
I would next encapsulate the availability factor, which represents the concept of availability in a class, for instance "AvailabilityStatus". The recommended attributes would be "date" and "status".
You have mentioned different status, for instance, available, booked, closed, under-maintainance etc. Each of these is a category. Let us say, numbered from 0 to n (where n<128).
The "date" attribute could be a java.util.Date object, representing a date. The "status", is byte array of 1440 elements (one element for each minute of the day). Each element of the byte array is populated by the number designation of the status (i.e, 0,1,2...n etc.), where the numbers represent the status of the minute.
The "Resource" class would carry an attribute of "resourceStatus", an ordered vector of "ResourceStatus" objects.
The object (all the objects) could be populated manually at any time, or the entire process could be automated (that is a separate area).
The problem of representation is over. You could add any number of resources as well as any number of status categories.
This is a simple solution, I do not address the issues of querying this information and rendering the actual schedule, which I believe is straight forward enough.
It is recognized that there are scope for optimizations/design rationalization here, however, this is a simple and effective enough solution.

Dreamweaver design question

Hi all. I'm new to the forum and ha da design question. My site took about 3 weeks to complete and after finishing what I though was a pretty error free website I noticed that dreamwever 8 was coming up with numerous errors that matched http://validator.w3.org's scans. My question is this. Why does dreamwever ( regardless of the release ) allow the designer of the website he/she is creating without pointing out the errors as they go along with simple instructions on how to fx them. As an example My meta tags
<META NAME="keywords" CONTENT="xxxxxxx">
<META NAME="description" CONTENT="xxxxxxxx">
<META NAME="robots" CONTENT="xxxxx">
<META NAME="author" CONTENT="xxxxxx">
<META NAME="copyright" CONTENT="xxxxxx">
all had to be changed over to
<meta name="keywords" xxxxxxxxxxxxx">
<meta name="description" CONTENT="xxxxxxx">
<meta name="robots" CONTENT="xxxxxx">
<meta name="author" CONTENT="xxxxxxxx">
<meta name="copyright" CONTENT="xxxxxxxx">
all because dreamweaver didnt tell me that the <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
didnt fit the original design. Now my site ( if you wish to view the code ) is www.gamblingwhore.com and if you look at the page source you will see that the code has been corrected on dw 8 but still shows more than 30 errors on http://validator.w3.org. Does dreamwevaer not have the basic tool available to fix these errors without such hassle. Its not just my site either, many sites built in dreamwever can be checked with the http://validator.w3.org website only to find more than 20 -100 different errors.
Dream weaver creators need to focus on these errors because they hinder seo and they create alot of extra work
Thank you

The w3c and XHTML have come a ways since the release of Dreamweaver 8 (I used it in late 2004 and 2005).
Dreamweaver 8 will build transitional XHTML files as well as old style single tag HTML. It all depends on the personal preferences of the designer.
Just for kicks, go to say... 20 random websites and see just how many get a green light when you validate them. If its half, you're lucky. This page doesn't even validate;
Dreamweaver has the menu option (at least in CS3 an CS4) under the Commands menu to "Clean Up HTML" or "Clean Up XHTML" depending on what you're building. I make a point of running that command as I build along with Apply Source Formatting.
I also use a local validator program to check my code before putting anything.
That's why they call it WYSIWYG software.
If it did everything perfectly for everyone every single time, good web designers would find themselves out of work.

WLAN 4402 Design question

Dear Support,
Wondering if anyone could help me, after some basic design advice on a WLAN implementation and if it is achievable.
Summary
VLAN 201 - Wired user LAN and 2003 Server running IAS (10.115.2.x /24)
VLAN 201 - Secure WLAN on 10.115.2.x /24
VLAN 60 - Management LAN for WLAN 4402 controller and 4 1130 LW (layer 2 mode) APs (172.16.31.x /24)
WLAN 99 - Guest WLAN with web auth (192.168.252.x /24).
I have a DSL router for the 192.168.252.x subnet for internet access for Guest users. A DHCP scope if configured on the WLAN controller
I am wondering if I can have the same subnet (and addresses assigned via the server running IAS) for both the wired users and secure WLAN.
Thank you for your assistance in advance.
I always rate helpful replies.
Best regards, Adrian.

Hi Ankur,
Many thanks for replying, ideally this is what I need to know is possible.
Currently the wired users on vlan 201, get an IP address via DHCP from the server, the same server is also configured with IAS for the implementation of MS-CHAP-V2 for authentication using their AD username and password (still yet to get working).
Ideally I would prefer that the wired and secure wireless (ms-chap-v2 on vlan 201) get their IP addresses from the same server. I need to know if it is possible to have both a wired VLAN and wireless WLAN using the same VLAN id (in this case 201).
I?m not over concerned with using either L2 or L3 mode on the APs, they currently are set to L2, but happy to define another scope either on the WLAN controller of the IAS (w2003) server.
Think the fundamental question I?m asking, is ;
Is it possible to have both the Wired users (VLAN 201) and Secure WLAN users (also on vlan 201) to share the same subnet. The reason this is crucial to the design is that the 10.115.2.x subnet is routed via a third party and getting them to add additional routes (i.e. one for the wired users and one for the wireless users is a pain! And a lot of paperwork!)
I have tried to do the config already the issues I have is that pings from the server to the management address of the WLAN controller sometimes work and sometimes don?t. I have 2 x 3560 switches doing the routing between the user (v201) and wlan management (v60). This is also the same in the opposite direction (4402 to the DHCP/IAS server). I am always able to ping the SVI of the v60 from the server. I'm also not seeing any authentication requests being passed to the IAS server.
Thanks again in advance for your assistance.
Best regards, Adrian.

Design question: methods returning objects

I have a general design question. When, in general (and why), should you have a method alter an object via it's methods but not return the object as opposed to doing the same operation in a method and then return it.
Consider the two below methods which do basically the same thing. When is one desireable over the other, and why?
Cheers--
public void setMyIntField(SomeObject pObj){
pObj.setSomeInt(5);
public SomeObject setMyIntField(SomeObject pObj){
pObj.setSomeInt(5);
return pObj;
}

Let me give a better example:
class FruitWorker{
private void someMethod(){
    HashMap myCitrus = new HashMap();
    HashMap myTropicals = new Hashmap();
    // use my no return obj method
    addFruitProps1(myCitrus,
                   "tartnes",
                   new FruitProperty("very!" ));
    // use my return object method
    myTropicals = addFruitProps2(myCitrus,
                                  "sweetness",
                                   new FruitProperty("little bit" ));
}// end method
private void addFruitProperties1(HashMap pFruitProps,
                                   String pProp
                                   FruitProperty pVal){
    pFruitProps.add( pProp,pVal);
}// end method
private HashMap addFruitProperties2(HashMap pFruitProps,
                                   String pProp
                                   FruitProperty pVal){
    pFruitProps.add( pProp,pVal);
    return pFruitProps;
}// end method
}// end class

LDAP design question for multiple sites

LDAP design question for multiple sites
I'm planning to implement the Sun Java System Directory Server 5.2 2005Q1 for replacing the NIS.
Currently we have 3 sites with different NIS domains.
Since the NFS over the WAN connection is very unreliable, I would like to implement as follows:
1. 3 LDAP servers + replica for each sites.
2. Single username and password for every end user cross those 3 sites.
3. Different auto_master, auto_home and auto_local maps for three sites. So when user login to different site, the password is the same but the home directory is different (local).
So the questions are
1. Should I need to have 3 domains for LDAP?
2. If yes for question 1, then how can I keep the username password sync for three domains? If no for question 1, then what is the DIT (Directory Infrastructure Tree) or directory structure I should use?
3. How to make auto map work on LDAP as well as mount local home directory?
I really appreciate that some LDAP experta can light me up on this project.

Thanks for your information.
My current environment has 3 sites with 3 different NIS domainname: SiteA: A.com, SiteB:B.A.com, SiteC:C.A.com (A.com is our company domainname).
So everytime I add a new user account and I need to create on three NIS domains separately. Also, the password is out of sync if user change the password on one site.
I would like to migrate NIS to LDAP.
I want to have single username and password for each user on 3 sites. However, the home directory is on local NFS filer.
Say for userA, his home directory is /user/userA in passwd file/map. On location X, his home directory will mount FilerX:/vol/user/userA,
On location Y, userA's home directory will mount FilerY:/vol/user/userA.
So the mount drive is determined by auto_user map in NIS.
In other words, there will be 3 different auto_user maps in 3 different LDAP servers.
So userA login hostX in location X will mount home directory on local FilerX, and login hostY in location Y will mount home directory on local FilerY.
But the username and password will be the same on three sites.
That'd my goal.
Some LDAP expert suggest me the MMR (Multiple-Master-Replication). But I still no quite sure how to do MMR.
It would be appreciated if some LDAP guru can give me some guideline at start point.
Best wishes

Design question for database connection in multithreaded socket-server

Dear community,
I am programming a multithreaded socket server. The server creates a new thread for each connection.
The threads and several objects witch are instanced by each thread have to access database-connectivity. Therefore I implemented factory class which administer database connection in a pool. At this point I have a design question.
How should I access the connections from the threads? There are two options:
a) Should I implement in my server class a new method like "getDatabaseConnection" which calls the factory class and returns a pooled connection to the database? In this case each object has to know the server-object and have to call this method in order to get a database connection. That could become very complex as I have to safe a instance of the server object in each object ...
b) Should I develop a static method in my factory class so that each thread could get a database connection by calling the static method of the factory?
Thank you very much for your answer!
Kind regards,
Dak

dakger

So your suggestion is to use a static method from a
central class. But those static-methods are not realy
object oriented, are they?There's only one static method, and that's getInstance
If I use singleton pattern, I only create one
instance of the database pooling class in order to
cionfigure it (driver, access data to database and so
on). The threads use than a static method of this
class to get database connection?They use a static method to get the pool instance, getConnection is not static.

Basic iPhoto questions:

I have some Basic iPhoto questions before I start using the program:
- does iPhoto apply any compression or change images in any way when they
are imported?
- after images are imported, can the original source folder of images be deleted off of the mac?
- can Quicktime files exported from iPhoto be viewed on a Windows computer?
- can iPhoto handle large resolution images that might be as large as 8-15mb each? does it display them quick? are there any known file size issues?
Thanks!!!!

kat.
Is there a way to use iPhoto on a network so other users can read and possibly write to an iPhoto library on a networked mac?
iPhoto is a consumer level photo organiser, not a server. It's possible to share photos but libraries are very difficult and fraught with the danger of database corruption. Some have reported success.
Is it possible to password protect or secure certain images in the library so they can not be seen by anyone?
No. The best I can suggest there is to create a second library and store it in a secure area like a protected dmg. But remember, you can only have one library open at a time.
After photos are deleted from iPhoto, are there any remaining traces or cached files anywhere other than the trash
If you delete photos from iPhoto and empty the iPhoto trash then the pics are removed from the Finder as well. They remain as findable as any other deleted file from that point, which is, very, if the searcher in knowledgeable.

SOA real-time design question

Hi All,
We are currently working with SOA Suite 11.1.1.4. I have a SOA application requirement to receive real-time feed for six data tables from an external third party. The implementation consists of five one-way operations in the WSDL to populate the six database tables.
I have a design question. The organization plans to use this data across various departments which requires to replicate or supply the data to other internal databases.
In my understanding there are two options
1) Within the SOA application fork the data hitting the web-service to different databases.
My concern with this approach is what if organizations keep coming with such requests and I keep forking and supplying multiple internal databases with the same data. This feed has to be real-time, too much forking with impact the performance and create unwanted dependencies for this critical link for data supply.2) I could tell other internal projects to get the data from the populated main database.
My concern here is that firstly the data is pushed into this database flat without any constraints and it is difficult to query to get specific data. This design has been purposely put in place to facilitate real-time performance.Also asking every internal projects to get data from main database will affect its performance.
Please suggest which approach should I take (advantage/disadvantage. Apart from the above two solutions, is there any other recommended solution to mitigate the risks. This link between our organization and external party is somewhat like a lifeline for BAU, so certainly don't want to create more dependencies and overhead.
Thanks

I had tried implementing the JMS publisher/subscriber pattern before, unfortunately I experienced performance was not so good compared to the directly writing to the db adapter. I feel the organization SOA infrastructure is not setup correctly to cope with the number of messages coming through from external third party. Our current setup consists of three WebLogic Servers (Admin, SOA, BAM) all running on only 8GB physical RAM on one machine. Is there Oracle guideline for setting up infrastructure for a SOA application receiving roughly 600000 messages a day. I am using SOA 11.1.1.4. JMS publisher/subscriber pattern just does not cope and I see significant performance lag after few hours of running. The JMS server used was WebLogic JMS

Object class deployment - Basic form question

OK, I subclass calendar object from Oracle provided standard
object class. What do I need to deploy to use this form now
apart from calendar.pll and my fmx. What about the object class
from which I sub-class. Do I need to compile and deploy that
also? How will form resolve this on run time the parent object
class as I really did not copy, just sub class and we do not
deploy original class? Basic form question. Thanks.

You can set the "help" property on the field (which gives you the little "information" icon link beside the field).
You could also try adding another field of another class above or below:
<Display class='InlineAlert'/>
<Display class='ErrorMessage'/>
<Display class='HtmlPage'/>
..etc

Workflow design questions: FM vs WF to call FM

Hereu2019s a couple of workflow design questions.
1. We have Workitem 123 that allow user to navigate to a custom transaction TX1. User can make changes in TX1. At save or at user command of TX1, the program will call a FM (FM1) to delete WI 123 and create a new WI to send to a different agent.
Since Workitem 123 is still open and lock, the FM1 cannot delete it immediately, it has to use a DO loop to check if the Workitem 123 is dequeued before performing the WI delete.
Alternative: instead of calling the FM1, the program can raise an event which calls a new workflow, which has 1 step/task/new method which call the FM1. Even with this alternative, the Workitem 123 can still be locked when the new workflowu2019s task/method calls the FM1.
I do not like the alternative, which calls the same FM1 indirectly via a new workflow/step/task/method.
2. When an application object changes, the user exit will call a FMx which is related to workflow. The ABAP developer do not want to call the FMx directly, she wants to raise an event which call a workflow .. step .. task .. method .. FMx indirectly. This way any commit that happens in the FMx will not affect the application objectu2019s COMMIT.
My recommendation is to call the FMx using u2018in Update tasku2019 so that the FMx is only called after the COMMIT of the application object.
Any recommendation?
Amy

Mike,
Yes, in my first design, the TX can 1. raise a terminating event for the existing workitem/workflow and then 2. raise another event to call another workflow. Both 1 and 2 will be in FM1.
Then the design question is: Should the FM1 be called from TX directly or should the TX raise an event to call a new workflow which has 1 step/task, which calls a method in the Business object, and the method calls the FM1?
In my second design question, when an application object changes, the user exit will call a FMx which is related to workflow. The ABAP developer do not want to call the FMx directly, she wants to raise an event which call a workflow, which has 1 step/task, which calls a method, which calls the FMx indirectly. This way any commit that happens in the FMx will not affect the application objectu2019s COMMIT.
My recommendation is either call the FMx using u2018in Update tasku2019 so that the FMx is only called after the COMMIT of the application object or raise an event to call a receiver FM (FMx).
Thanks.
Amy

Method design question...and passing object as parameter to webserice

I am new to webservice...one design question
i am writing a webservice to check whether a user is valid user or not. The users are categorized as Member, Admin and Professional. For each user type I have to hit different data source to verify.
I can get this user type as parameter. What is the best approach to define the method?
Having one single method �isValidUser � and all the client web service can always call this method and provide user type or should I define method for each type like isValidMember, isValidAdmin ?
One more thing...in future the requirement may change for professional to have more required field in that case the parameter need to have more attribute. But on client side not much change if I have a single isValidUser method...all they have to do is pass additional values
isValidUser(String username, String usertype, String[] userAttributes){
if usertype == member
call member code
else if usertype = professional
call professional code
else if usertype = admin
call admin code
else
throw error
or
isValidMember(String username, String[] userAttributes){
call member code
One last question, can the parameter be passed as object in web service like USER object.

First of all, here is my code
CREATE OR REPLACE
TYPE USERCONTEXT AS OBJECT
user_login varchar2,
user_id integer,
CONSTRUCTOR FUNCTION USERCONTEXT (
P_LOGIN IN INTEGER
P_ID_ID IN INTEGER
) RETURN SELF AS RESULT
Either your type wont be compiled or this is not the real code..

Aggregation level - design question

Hi, All
we are in BI-IP ( Netweaver 2004s SPS16).
I have a design question for this scenario.
User needs to plan the amounts for a duration (start period and end period), Jan2008 -Dec2008 (001.2008, 012.2008) = 12000.
We need to distribute this to the periods equally. 001.2008 = 1000, 002.2008 =1000 .... 012.2008=1000.
If the user changes the period amounts, it should be reflected back in the duration amount.
Pl suggest the design for the aggregation levels to achieve this.
Thanks in advance.
velu

Hello Velu,
As the name also goes, creating an "aggregation level" will only result in "aggregation". What your requirement is, is called disaggregation or distribution - this cannot happen automatically - you will either have to use the feature in input queries or use the distribution planning function or create your own planning function using fox/exit.
