What are the functions of look and feel files?

Hi,
If some one can explain me what are individual role in look and feel of the ISA B2C application.
mainFS.jsp
main_inner.jsp
catalogFS.jsp
accountFS.jsp
refresherB2C.jsp
I want to know function of each files. If I change any file then where exactly I can see changes which I made.
Any help from any one highly appreciated.
Thanks.
Ashish

Hi,
If you get hold of the ISA Development and Extension guide there is a section highlighting which frames go where in the main application.
You can also see which .jsp pages are displayed where by adding the following parameter to the root URL of the application when you logon.
http://<host>:<port>/b2c/b2c/init.do?showmodulename=true
This will display the name of each jsp page in the frames on screen.
Also, surely you must have been asked to change certain aspects of the application - not specific files? You shouldn't just change the files and then "see what happens"...
Hope this helps,
Gareth.

Can anyone help me what is the use of business and proxy service in osb?

Hi,
I am new in Osb what is the use of business service and proxy service in osb.
I know little bit proxy service is used for actual message flow. I saw some project proxy service invoking the (using service callout,routing and publish) service,but the wsdl of the services of the proxy and business service is same.
Please can anyone explain the flow while executing through soapUI?(that means it will hit 1st business services or proxy service)
I have this project structure
business service
1.reference.biz----> this is the wsdl of ex:reference.wsdl
2.external.biz----> this is the wsdl of ex:external.wsdl
proxy service
1.referece.proxy--->this is the wsdl of ex:reference.wsdl(in this proxy we are routing to reference.biz proxy service both contains same wsdls why?)
xqueries of request and response.
Best Regards,
Raju.

Hi Raju,
Proxy Service - It is the starting point of you OSB application which deal with receiving messages, inducing logic in it like transformation, if-else, replace, java call outs,etc. You can put in your program logic here and then invoke a business service to route it to your Database or to any other queue as per your requirement.
Business Service - It is generally used for routing purposes, like inserting the input in your Database or sending it to a different queue or BPEL process, etc..

What is the difference between SmartNet and SMBS service level

Good Afternoon
I would like to ask if what is the difference between Cisco's SmartNet and Cisco's SMBS service level?
Thank you

Hi Rey,
SMARtnet covers traditional Cisco products (enterprise products ie. ISR routers), Small Business Support Center covers the small business line.
In the UC group of products, for some reason, Cisco considers the UC520, AP521, and WLC526 which are branded small business to be traditional Cisco products and are covered under SMARTnet. But, the UC540 and UC560 are covered by SBSC. One major difference in the UC arena is the support for CLI vs CCA config.
However, I noticed your post was in the Small Business - switches category. If you have a small business switch those are covered by SBSC not TAC. SBSC will support the CLI and web gui config of the small business switches, where CLI is applicable to the model.
SBSC contracts tend to be for 3 year periods and can be significantly less expensive than SMARTnet agreements.
Hope that helps.
Best,
David

What is the most demaming develop dba out for as oracle 10g?

I am look into develop a dba to sale, what is the most demaming database out
there for company small to mid business?

OcpJames,
As I understand it you want to develop an HR application for resale. I developed a HR/Personnel Management System a long time ago. It took a long time to develop mostly due to the many layers of reporting and government regulation that must be accounted for, and was a hard sell. I'm sure by now that has gotten even worse with Sarbanes/Oxley, etc. In addition many states having differing regulations and reporting. I would be extremely surprised if any company would risk running their HR system on a remote server or would use a remote DBA due to the risk involved, since they are directly responsible under the law. However, you might be able to find a niche market where you can fill a need, and that is certainly what I would aim for. Study the marketplace and determine what that would be, try to find a customer that will work with you and go for it.
Keep Smiling,
Bob R

MBRC and SYSTEM STATISTICS in Oracle 10g database.

Hi All,
I am performing database upgrade from Oracle 8i Solaris to Oracle 10g HP-UX using exp/imp method.
But i do have some doubts regarding MBRC and System statistics.
MBRC in Oracle 10g is automatically adjusted if MBRC parameter is not set, but i found value 128 as shown below.
SQL> select * from v$version;

db_file_multiblock_read_count        integer                          128Also i performed one simple full table scan to test it...but db file scattered read is performing on 128 blocks. So i dont think 128 is suitable and is automatic, i mean MBRC is not set accrodingly it always uses 128.
Does this MBRC value affects whole database performance?

What is the relationship between Process and Session parameter in Oracle

Hi All
I ran into a problem
"ORA-00020: maximum number of processes (150) exceeded " on the other day and I want to fix this temporary by increase the process by some number like 200.
Someone suggesting the syntax to fix my problem then the database must restart after running this command.
alter system set processes=200 scope=spfile;
However, I check the v$Paramenter view I see 2 values I believe they go together are
Processes: 150
Sessions:170.
Here are my questions:
1. "alter system set processes=200 scope=spfile;" is the correct way to increase the max Processes?
2. Do I have change the number of Sessions after changing the number of Processes?
3. Is there other way to increase the processes number without reboot the Oracle database?
Regards,
Jdang

According to the Oracle version# Reference manual which documents the database parameters sessions is set to 1.1 * process + 5 using the 10gR2 version.
Basically an Oracle process cooresponds to an OS process that performs the actual work for the session.
An Oracle session is a collection of memory structure entries that identifies and keeps track of what is being done for a client of the Oracle database.
Sometimes a single background process will support multiple sessions even in dedicated server mode such as when recursive SQL is performed to support the DML statement being done in the session.
PS - you should consider increasing processes first and only increase sessions if you still have an issue.

Find sequence and thread number of Oracle 10g Database

Hallo!I am a newbie Oracle DBA studying for OCP.I am trying various methods of performing flashback of the database.
Out of these options there is one that uses the sequence and thread numbers of the database as below

How can I find out current sequence and thread numbers of the db to enable me implement such a flashback strategy?
Thanks.

Oracle 10g database as Resource manager and heuristic transaction decision

Hi,
I have read in documents about distributed tarnsaction that resource manager like oracle databasecthat are involved in distributed transaction can take heuristic decision(unilateral decision) and can either rollback or commit the transaction associated with itself without having confirmation from the transaction manager.
I want to know how a resource manager take this unilateral decision and can we set this as parameter either in resource manager or in application server.
Thanks in advance

Hi,
Following are some links to documents.
Handling Heuristic Completions
http://edocs.bea.com/wls/docs81/ConsoleHelp/jta.html
A heuristic completion (or heuristic decision) occurs when a resource makes a unilateral decision during the completion stage of a distributed transaction to commit or rollback updates. This can leave distributed data in an indeterminate state. Network failures or resource timeouts are possible causes for heuristic completion. In the event of an heuristic completion, one of the following heuristic outcome exceptions may be thrown:
HeuristicRollback—one resource participating in a transaction decided to autonomously rollback its work, even though it agreed to prepare itself and wait for a commit decision. If the Transaction Manager decided to commit the transaction, the resource's heuristic rollback decision was incorrect, and might lead to an inconsistent outcome since other branches of the transaction were committed.
HeuristicCommit—one resource participating in a transaction decided to autonomously commit its work, even though it agreed to prepare itself and wait for a commit decision. If the Transaction Manager decided to rollback the transaction, the resource's heuristic commit decision was incorrect, and might lead to an inconsistent outcome since other branches of the transaction were rolled back.
HeuristicMixed—the Transaction Manager is aware that a transaction resulted in a mixed outcome, where some participating resources committed and some rolled back. The underlying cause was most likely heuristic rollback or heuristic commit decisions made by one or more of the participating resources.
2. Understanding EJB Transaction
http://www2.sys-con.com/itsg/virtualcd/Java/archives/0504/tyagi/index.html
Unilateral Decisions
The transaction manager allows certain heuristic or speculative decisions to be made based on the state of all participating resources in a transaction and the underlying two-phase commit protocol. A heuristic decision occurs when one of the resources in the transaction unilaterally decides to commit or roll back the transaction without permission from the transaction manager
3. Oracle® Containers for J2EE
http://download.oracle.com/docs/cd/B31017_01/web.1013/b28958.pdf
Heuristics
To achieve consensus, two-phase commit is a blocking protocol. This means that, if a coordinator fails before delivering the final phase messages, the participants must remain blocked, holding onto resources. Modern transaction systems add heuristics to two-phase commit, which allows such participants to make unilateral decisions about whether they will commit or rollback. If a participant makes a choice that turns out to be different from the one taken by other participants, then non-atomic behavior occurs.
I got this problem while trying to do a distributed J2EE tarnsaction with two XA (one MQ and other Oracle 10g database XA) and one non-xa (oracle 10g database). According to above docs a resource manager can decide tarnsaction final state unilaterally and that can result in unatomic transaction.
Do oracle also make such decision and if yes then on what ground it takes decision? Can we change this according to our requirement either always rollback/commit anywhere as parameter setting?
Thanks

What are the functional differences between the iPhone and the iPod Touch, barring of course the differences in service requirements.

For one, their form factors are slightly different as the iPhone has a bit more squarish body whereas the iPod Touch has a tapered back to it.
The iPhone also has much better front and rear cameras. Exact details as to the difference in megapixels depends on whether or not you talking about the iPhone 4 or 4S. If you would like to get more details, you can always view
each models specs on Apple's online store.

What is the difference between subroutine and function module?

What is the difference between subroutine and function module?

Hi,
they can both return values.
FMs are mainly used when a routine is to be performed by many programs.
Subroutines (forms) are generally only executed within one program.
You can perform routines from other programs, but it's not often done.
both forms and FMs are reusable modularization units.
To distinguish we generally say that forms are used for internal modularization and
FMs are used for external modularization.
To decide on which to implement, consider whether you need the content to be used just for a limited program
or wheteher it can be called from many independent programs.
For the first purpose it is better to implement a form whereas for the second we implement an FM.
However, ABAP does not isolate the usage context.
That is; you can call a form from another program within whose code the form is not actually implemented.
However, this requires attention since the form may utilize global variables.
The same issue holds for FMs.
FMs are encapsulated in function groups and function groups may have global variables that can be globally
used by all FMs inside it.
Thanks,

What is the function of the Slice and number 4 LUTs in cRIO9104 FPGA?

When I compiled the FPGA VI, the compliation report tell me that there is limitation of the resources pf FPGA, the FPGA that I am using is cRIO9104. Do you know what is the function of the slice and number 4 LUTs in FPGA? Which FPGA LAbVIEW code need to use these FPGA resources? And I have attached the compliation report for you as a reference.
Thank you for your helping!

You've simply got too much code to fit the available resources on that one particular FPGA, just as the error message says. I would take the error message's recommendations, or split up the functionality into two FPGA's.
By the way, LUTs are lookup tables, one way the compiler implements your code. Slices are areas that run independently (general case) of any other slice and how the FPGA achieves true parallel processing.
