THICK CLIENTS & THIN CLIENTS
Can any body please tell me in detail what is the difference between a Thick client and a Thin client. Also tell me using either of these in specific occassions.
And it's normally called a 'Rich Client' not 'Thick Client'.No, "rich client" is a newer developer.
s/developer/development/I think it's more than a when Sales/Marketing people wanted to promote thin client solutions (during the fashionable thin 90's) they used devisive language of (Thick/Fat) against the alternative traditional Client Server solutions even though these could be Rich or Thin. I remember when Applets where considered thin, then it had to be Web-Pages to be really Thin and now that things have gone full circle with the introduction of things like AJAX and WebStart they use the old^Wnew terminology, or Rich Clients to distance it from the negitive associations of Thick and Fat.
To me, fashions come and go but they will always be Thin or Rich :)

Distributing a Java EE Application Client (Thin Client)
Hi,
I'm following the instructions in Section 4 Developing a Java EE Application Client (Thin Client) in Oracle® Fusion Middleware Programming Stand-alone Clients for Oracle WebLogic Server, 11g Release 1 (10.3.1), Part Number E13717-01.
I packaged the application client in an ear. If I set up my environment using C:\bea10\wlserver_10.3\server\bin\setWLSEnv.cmd. I can extract the application client using a command line like:
java weblogic.ClientDeployer myear.ear myclient
I can execute the client using a command line like:
java weblogic.j2eeclient.Main myclient.jar t3://localhost:7003
However, I would like to run the application client on a client machine (i.e., a machine without WebLogic installed). I thought I could use one of the wl*client.jar files such wlclient.jar, wlfullclient.jar, etc. I started with wlfullclient.jar.
If I try to extract the application client with a command line like
java -classpath wlfullclient.jar weblogic.ClientDeployer myear.ear myclient
I get the following error:

Next I tried using the jar previously extracted on the server and tried to run it using:

Is it possible to extract and execute an application client on a machine without WebLogic server? If so, what jars do I need? If not, why not?
I'm testing using WebLogic 10.3.1 on a Windows XP SP2 machine using JDK 1.6.0_05.
Thanks in advance,
KeithHello,
I tried doing pre-compilation of jsps using the weblogic.appc and getting the below exception.
Can any one advise the jar file containing the below class file so that I can add in the classpath and try for it.

Difference bewteen thin client and thick client
Hi:
can someone explain the difference between the thin client app and thick client app?Thin Client: Little to no logic on front end. Typically a 3 tier architecture. Example is a web browser
Thick Client: Typically a client-server type architecture where some business logic/processing occurs on the front end -
HFM Thin Client and Thick Client
Hi
can anyone tell me what is HFM thin client and thick client
ThanksThick client is the actual application client view. Most administrators limit that view to only them and provide a workspace (the thin client) as a method of accessing hfm. This is because more can be done in terms of metadata and security changes in the thick client than the thin client.

Diff between Thin client and Rich client
Hi Everyone,
Can someone give me a clear picture of the what is the diff between Thin client and Rich client.
Thanks,
KrishnaHi,
thick client (rich client) has/stores all the data inside itself
so it can do application processing without the server with data
thin client uses resources from host computer (from server)
and wihtout that you are not able to work with that kind of client
does that answer your question ?

Arch Linux as Thin Client, PXE, LTSP
Hey there all, been using Arch for about a year now, from Gentoo through Zenwalk, gotta say that Arch is bar none the best so far. I think it's the way that it doesn't try to hide the system internals through abstraction (where every distro has it's own abstraction methodology).
I'm thinking in the future that I'd like to do a network-wide deployment of "terminals" for a non-profit. I say "terminals" in because unlike a true thin client, the idea was to have PXE booting to NFS and using the local hardware more. I'm fond of the idea of centralizing system management to a single system installation, and using solid-state machines.
VNC, NX, RDP seem to be out of the question because I need clients to have native multimedia applications like the Flash plugin, and Skype. I could see audio and video redirection becoming a pain. But having the full installation on the client doesn't seem like the right thing to do because then I've got specific machines with specific problems that I'd have to diagnose. Virtualizing an entire OS session for each user would require a powerhouse server, and then we are stuck with a graphical redirection like VNC, NX, RDP. Linux Terminal Server Project really seems to be on track, they've got a great customization method, but again, they're using XDMCP and sending raw X data over the network.
I envision the clients as being mostly web browser-centric to interface with the necessary applications, and using software like Sun Global Desktop or NoMachine NX to connect to individual Windows applications on a Windows server when needed.
I'm looking at the Fit-PC2 as a possible thick-client solution. It's an Intel Atom based PC with an AMD Geode graphics solution, 512MB of soldered RAM, really low energy consumption.
The wiki doesn't seem to address having more than one client using an NFS-mounted root. If you have more than one client writing .pid and other /var files, this doesn't seem like a feasible idea.
So I suppose that the / has to be mounted in RAM, and only the static dirs like /usr /bin /boot swap are NFS imports?
At first the network would be homogenous, but if we add computers with differing graphics cards
So, in summary:
* Any clues on multiple clients using one NFS root?
* How to autoconfigure X.org and other differing hardware?
It sounds like a fun challenge, wondering if anyone else has tried anything like it.
Last edited by VitaminJ (2009-10-19 00:42:31)I don't really know enough about this to offer any real advice, but as far as multiple machines using a single NFS root goes, you could look into mounting it on all your clients read-only, and using a union filesystem (eg aufs2, unionfs), such that you can use another partition (say on a ramdisk) to handle writes...

How to use authid with rwservlet via WebLogic Thin Client
1. Using J2EE Thin Client for WebLogic (WL) to submit interactive requests for Oracle Reports (App Server 10g) running on another server without SSO.
2. After starting basic Infrastructure, we start rwserver in batch mode (no other mid-tier components are used).
3. It appears that the cgicmd.dat file in the Thin Client conf directory on the WL server controls the DB access with the key:connect string info it has.
4. We had been allowing the testers to come in via the web through a SunOne (iPlanet/Netscape) web server instance, which in turn connects to the WL server running the Thin Client instance.
5. We noticed that anyone could run rwservlet to view report status with the showjobs command via a URL through the same mechanism as point #4 above, and were concerned about security of the reports - "bad".
6. Then someone realized the showmap command could also be specified, and thus see the DB connect string (Id/pw/SID) - "worse".
I researched securing Reports, and read through the white paper, "Securing Oracle9i Reports", and although it discusses security without using SSO, all it says is "users accessing a secured instance of Oracle9iAS Reports Services will be challenged to identify themselves by the Reports Servlet, using its own authentication mechanism (as with Reports6i)", but I can find no explanation of how that works, nor how it would work with the WL Thin Client.
Questions:
1. How are the Id's/passwords set up under AS 10g "as with Reports6i" in this environment going through the WL Thin Client?
2. Is there anything else that needs to be done to secure the created reports, and the connect string info (i.e. using authid with rwservlet?showjob, and not allowing the rwservlet?showmap to be executed at all)?
TIA,
ROCthe JDBC Developer's Guide (11gR2)
gives an example in chapter 9 under "JDBC Thin Driver Support for Encryption and Integrity", sub- "Setting Encryption and Integrity Parameters in Java"
from Oracle SQL Devloper, without redirecting the client to use the OCI/thick driver, choose, new database connection, connection type Advanced. add the entry from the example noted above to the Custom JDBC URL form.
for example:
Properties prop = new Properties();
prop.setProperty(OracleConnection.CONNECTION_PROPERTY_THIN_NET_ENCRYPTION_LEVEL,"REQUIRED");
prop.setProperty(OracleConnection.CONNECTION_PROPERTY_THIN_NET_ENCRYPTION_TYPES,"(AES128)");
OracleDataSource ods = new OracleDataSource(); ods.setProperties(prop); ods.setURL(jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xxxx)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=xxxx)(INSTANCE_NAME=xxxx))));
Connection conn = ods.getConnection();
strange side note!, we could not get this to encrypt unless the sqlnet.ora file included the SQLNET.ENCRYPTION_SERVER=required. if this was set to default(accepted), and even though the jdbc thin client properties set to required, the network traffic was still clear text.
good luck -
12.1.3 EBS with JDBC Thin Client
Hello,
I have question about JDBC Thin Client, typically dbc file and context file define connection to RAC Database using thin client, as far as I know jdbc thin client does not support TAF feature when there is database node down, the connection not direct to surviving node until relogin.
APPS_JDBC_URL=jdbc\:oracle\:thin\:@(DESCRIPTION\=(ADDRESS_LIST\=(LOAD_BALANCE\=YES)(FAILOVER\=YES)(ADDRESS\=(PROTOCOL\=tcp)(HOST\=XXXX-SCAN.xxx.com)(PORT\=1521)))(CONNECT_DATA\=(SERVICE_NAME\=DBSID)))
<jdbc_url oa_var="s_apps_jdbc_connect_descriptor">jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=YES)(FAILOVER=YES)(ADDRESS=(PROTOCOL=tcp)(HOST=XXXX-SCAN.xxx.com)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=DBSID)))
And parameter APPS_JDBC_DRIVER_TYPE=THIN in dbc file, is it must to be THIN? What is the function of FND_JDBC_USABLE_CHECK=false/true?
Also to make connection work to surviving database node, we need to restart process OACORE that connect to down node, is that expected behavior and workaround? Is there a way or is it supported to use THICK client in R12 EBS?
Thank you.Please see the following docs.

Adobe Air Vs Thin Client Application
Hi,
I have very little knowledge of Adobe Air. I would like to
know the basic difference between Adobe Air & thin client
applications.
Also, does Adobe air supports web applications? if yes then
how it interacts with centralize database which resides on main
server?
Does Adobe Air works only with MySQL?
Can anyone help on this?
Thanks in advance!!quote:

& thin client applications.
I don't see that there necessarily is a
difference. You can use AIR to build a thin client. You can use AIR
to build a thick client. It's a tool. It doesn't tell you what to
build.
quote:
Also, does Adobe air supports web applications?
AIR includes several networking facilities which
can be used to interact with a web server.
quote:
how it interacts with centralize database which resides on
main server?
It can do it the same way a browser does: by
sending requests over HTTP, handled by server side code that
manipulates the DB. If you have a "Web Service" API, AIR supports
all the SOAP ****, too. And, there is a raw network API if you have
to hand-roll your low-level protocol.
quote:
Does Adobe Air works only with MySQL?
AIR doesn't support MySQL at all. The only
native DB support it has is for SQLite, which is used for databases
on the local file system where the AIR app resides. To access a
remote DB, you have to use some form of custom networking to reach
it.
Theoretically, you could write a MySQL network client using
the raw client socket functionality, but I don't believe this
protocol is documented. You could extract it from the MySQL source
code, but...eck. Better to set up some kind of web service
API. -
Hello experts,
Rich contents are data manager, console, import manager and syndicator GUI clients
thin contents are portal way of looking mdm using iviews.
is this true??
Regards
Eva MHi Eva,
Good Day !
You are right .
A thing client (generally a software application/portal) depends primarily on a central server ( MDM server in this case) .It will drive communicating inputs from user to server and delivering back outputs from server to the user.Thin clients are independent of the machine you are using .
Eg:Portal
A thick client passes on data from an MDM user to Server . Such clients are generally used for performing data storage and processing activities directly at server level.Thiick clients need dedicated installations of GUIs and are machine dependant.
Eg:data manager, console, import manager and syndicator GUI clients
Hope this clarifies your query.

Thin Client IP phones for VDI solution
Is it possible to have a Cisco IP phone to act as a thin Client for VDI solution?
Can anybody suiggest meHello Sivakalam2
You ask an excellent question, and one that will likely trigger a heated discussion. I've had interest in the same topic for several years, and surprisingly found very little online. Everyone makes a thick client. WebRTC is a development project which is making inroads toward thin client softphone functionality. It's an excellent concept, but I haven't seen a production-ready client, yet. (Not saying there aren't any; I just have not seen them.)
Then I came upon this info in the Cisco Unified Communications System 9.0 SRND:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/9x/collabor.html
Cisco Virtualization Experience Client Architecture
Cisco Virtualization Experience Client (VXC) endpoints enable the end users to have secure real-time access to content and business applications as well as a rich collaborative user experience. These endpoints provide access to collaboration services that are part of the larger Cisco Virtualization Experience Infrastructure (VXI) solution. For information on a complete end-to-end VXI solution design, refer to the documentation available at
http://www.cisco.com/en/US/solutions/ns340/ns414/ns742/ns1100/landing_vxi.html
Deploying Cisco Virtualization Experience Clients
Cisco Virtualization Experience Clients (VXC) are endpoints in the Cisco Unified Communications portfolio; however, they are more than just simple endpoints because they interact with a user's working environment by providing voice, video, and virtual desktop capability and functionality. A user's work environment can assume various profiles (for example, task worker, knowledge worker, or mobile worker), and Cisco has various Virtualization Experience Clients to meet those different needs.
The Cisco VXC 2111 and VXC 2112 provide an integrated form factor that is paired with a Cisco Unified IP Phone 8961, 9951, or 9971 for a fully integrated voice, video, and virtual desktop environment. The Cisco VXC 2211 and VXC 2212 provide a standalone form factor that can be used as simply a virtual desktop (for a task worker), or they can be paired with an IP phone for a fully integrated user environment. The Cisco VXC 4000 provides a software-only solution by using a re-purposed PC to provide the user with voice and virtual desktop functionality, while the Cisco VXC 6215 provides a Linux-based thin client for fully integrated voice, video, and virtual desktop in a single device.
I do not have direct experience with these clients yet, having upgraded to CUCM9 recently. I'm definitely going to research it now. There's much more info in the SRND link above to read.
Thanks
