Why should we use BRTOOLS for oracle data backup?

Hi there,
Any one of you have any idea on specific advantages with using BRTOOLS for backup over using only Oracle RMAN?
Are there any advantages using brbackup in databackups which we do not get with RMAN alone?
thanks
Arlin

i seriously doubt you want to use wsdl4j unless you are doing really advanced webservice work. assuming you are developing this webservice from scratch, you basically want to use JAXWS: define an appropriate interface and your value classes, and let JAXWS do the rest. metro is the JAXWS implementation included in the oracle jdk and it has great tutorials and reference documentation online. i'd suggest you start here: http://metro.java.net/getting-started/

Why should we use WSDL for developing webservices

I need to develop Webservice Application for our Client .
I dont know anything about WSDL4J
Hi from the net i found this
"The Web Services Description Language for Java Toolkit (WSDL4J) allows the creation, representation, and manipulation of WSDL documents.
Is the reference implementation for JSR110 'JWSDL' (jcp.org)."
But anybody please tell me why should we use WSDL for developing webservices ??
Is there any specific advantage we will get ??
And Can body please point me a link where to start for working with WSDL4j ?
Thank you very much

CCMS is used for system monitoring , why should we use solution manage ?

CCMS is used for system monitoring , why should we use solution manage ?
Whats the relationship between CCMS system and SolMan?
Thank you .

hi,
I just want to ask a question. At our client we have solution manager and CCMS. There is data in CCMS I can extract, it is loading on BW side ok the same number of recs, but the problem on CCMS cubes says there are the same number of record in the cube and also showing as the data is ready for the reporting. But when I run the report and view the data as listcube it is empty.
ANy of you have the situation like this cube say it has the data but when do th BEX or infocube contents the cube is empty nothing in there. The same thing is happening with hourly, 15 minute and daily cubes.
Anyhelp on this matter is appreciated

What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

Hi All,
I am new to TestStand. Still in the process of learning it.
What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
Thanks in advance,
LaVIEWan
Solved!
Go to Solution.

Hi,
Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

Why should I use BO BI 4.0 for my existing SAP NetWeaver ?

Dear Sirs,
Question about BusinessObjects BI 4.0 & SAP Netweaver 7.0.
In my company we use NetWeaver for a year. We have some reports on portal, so we have some analysis via www. It seemed to me that this is enough for us.
Now on the market is available new version of BusinessObjects - version 4.0.
My question is :
Why should I use BO BI 4.0 for my SAP BW?
What will I gain by implementing BO BI 4.0 in conjunction with SAP BW?
Can I use existing reports on the new platform?
Can you give some links to documents, presentations and notes to answer these questions?
Best regards,
Emmo

Hi Emmo2000,
Please see my answers below:
Why should I use BO BI 4.0 for my SAP BW?
What will I gain by implementing BO BI 4.0 in conjunction with SAP BW?
Please see this SDN article which covers a lot of the new features of BI4.0 :
/people/ingo.hilgefort/blog/2011/03/24/sap-integration-update-9--should-you-start-with-sap-businessobjects-40-or-wait-for-41
Can I use existing reports on the new platform?
There is the ability to integrate BexWeb applications via our BI Launchpad. I'm not sure if this is what you are referring to but the following should clarify:
http://wiki.sdn.sap.com/wiki/display/BOBJ/HowtointegrateBExWebApplicationsintoBI4.x
Can you give some links to documents, presentations and notes to answer these questions?
For detailed information on the BI4.0 suite, I would direct you towards our product documentation:

I hope this is helpful and fully answers your question.
Kind regards,
John

Why should we use DSO instad of Infocube i BW7.4-SAP BW7.4

Dear All,
now I'm working with HCM- Payroll (BWreports) Standard reports, data flow is datasource--->Infocube--->Reports, but my architecture given data flow datasource--->DSO--->Multiprovider-->Reports, this is in SAP BW7.4, could any one explain me why should we use DSO instead of infocube..
Thanks for your helping...
Regards,
Narasimha

Hi
In Loading purpose:
Better to use DSO, becouse it involves 3 tables ie New data table, Active data table and Change log table.
in case of INFO CUBE, here it involves more than 3 tables ie by default 3 dimension tables are existedby SAP... at least we will create 2 tables ie 1 dimension table and 1 fact table ....here it involves 5 tables.( 3 default+1 dimension+1 Fact table)
Conclusion: When we create INFO CUBE it will takes more time compared to DSO because it involves 3 table
Conclusion: Best practice is when we load data to taget, better to use DSO
In Reporting:
Cube will give summerised data whyle reporting and it is multi dimensional,ie we can analyse the data in multiple ways.
DSO will give detailed data whyle reporting and it is 2 dimensional , ie we can analyse the data in 2 dimensional way only
Conclusion: Best practise is Whyle reporting better to use INFO CUBE

64 bits: why should I use it?

Just for the sake of discussion: If I have a program offered in 32 and 64 bit modes, why should I use the 64 bit version?
For example, the well known Videolan Player, aka VLC Media Player, recently updated to version 1.0.2, comes in 32 an 64 bit flavors. When would one version be used in lieu of the other?
And saying "because it is bigger and hence better" is not true. Even Apple points out in the developer pages about the 64-bit fallacy: in that mode, all data structures duplicate in size and if the hardware remains the same, performance will suffer cause you have to push twice the amount of information.

I just did a test with VLC Player (version 1.0.2), I played the same video in both 32 bit and 64 bit modes (NOTE: NOT talking about the kernel, but the program). Played it several times in both modes and even alternated between modes. In 64 bit mode it caused one of my processors to spike to 104% usage for the first 20 sec before dropping to 4-5%. In 32 bit mode processor usage remained at 4-5% the entire time.
Played the same video in Quicktime Player X in both modes and saw no difference (used 5-8% processor usage).
So to answer the question about when to use one version over the other I would say if one version causes notable problems/issues and the other doesn't than use the one that doesn't. Generally you shouldn't see a noticeable difference except in high-end programs that are crunching massive amounts of data.

Why do we use dunning for vendors

Hi All...
We create dunning for customer to send them reminders for payment....But why do we use dunning for vendors (in Vendor Master Data)??
Txk,
Umesh

Hi,
If you dun customers who are also vendors and want to clear the items, the dunning program lists both the overdue customer items and the overdue vendor items in the dunning proposal, and determines a joint balance.When you dun a customer who is also a vendor, only the master record information of the customer is relevant.The items can only be cleared if the same dunning procedure has been defined in the standard dunning area for both customer and vendor.
Hope this helps you. let me know if you need anyother information.

Export import - using TOAD FOR ORACLE and ORACLE DATABASE 10G EXPRESS or s

Hi all,
Could you please kindly help me?
I am using TOAD FOR ORACLE to export a table to flat file A. The tool just supports to distinguish fields by "spaces".
And the web page of ORACLE DATABASE 10G EXPRESS to import the data from flat file A to another database. To load data to a table from a text file, the web page bases on "comma" to distinguish fields.
So could you have any suggestion for me? I need to export data via TOAD FOR ORACLE. And then import it to another database by the home page of ORACLE DATABASE 10G EXPRESS or sqlplus.
Thank you so much for your help!

Dont use TOAD for exporting your data. Use PL/SQL. Below is the code given in Asktom.com that does what you want.

Microsoft OLE DB Provider for Oracle: Data type is not supported.

I got the error:
Microsoft OLE DB Provider for Oracle: Data type is not supported.
Shortly after upgrading from Oracle 8 to Oracle 9. I was advised to download more up to date oracle drivers, but I was wondering if there was a way to tell what version of the 'OLE DB Provider for Oracle' is already at. Is there a command I can use via SQL Plus or something?

I have found Microsoft ODBC for Oracle to be more stable than the Microsoft OLEDB for Oracle driver. I have also found both Microsoft ODBC and OLEDB drivers to be more stable than the drivers from Oracle.
You could always get the latest MDAC (Microsoft Data Access Components) from Microsoft's MSDN Download site and then get the ODAC (Oracle Data Access Components) from Oracle's OTN Download site. ODAC requires MDAC. And ODAC has the latest drivers.
I suppose it would help to have the latest patches for your Oracle client software too. Maybe Oracle MetaLink would have these?
It may even help to have the latest service pack for Visual Studio 6 (Visual C++ 6 and Visual Basic 6) too.

Use case for financial data

Hi All,
I've a question about potential use case for Oracle spatial. Data structures are following:
Clients
Account (have a dimension of balance, can be zero or above zero)
Client to account relationship
E.g.
Client C1 is a borrower to Account A1 (balance = 0)
Client C1 is a co borrower to Account A2 (balance > 0)
Client C2 is a co borrower to Account A1 (balance > 0)
Client C3 is a co borrower to Account A3 (balance > 0)
Currently, database is modeled as a set of three tables, e.g.
Client
ID
DATA
Account
ID
DATA
BALANCE
CLIENT_TO_ACCOUNT
CLIENT_ID
RELATIONSHIP (E.g borrower)
ACCOUNT_ID
Business limitations:
We are not interested in independent graphs for which all accounts have balance = 0 (let's call it inactive graph), however we might need occasionally query it
Users are interested in vertices/edges with account which have balance = 0, but linked (up to level N) to active account for analysis purposes
There is no well defined root (e.g. there can be 2 or more clients which are co borrowers to same account)
99% of queries will be against active graphs
Graphs are mutable, e.g. new relationships (edges) may be created/deleted during the day
Users are potentially interested in free navigation in whole independent graph, starting from root.
Root is determined by certain business rule
Need to process active graphs daily as bulk
Problems which I am trying to solve:
Limit the amount of data which may need to be processed - based on the analysis of current system, we only need 5% of data + some delta for 99% processing
Make sure performance does not degrade with time as we get more historical (processed data) - we can not deleted accounts with balance = 0 as potentially new relationship may arrive with new accounts with balance > 0
Current solution that I am thinking of :
Artificially partition the data universe as active and inactive graphs. All indexes would be local to two partitions.
E.g.
GROUP
GROUP_ID PK
ACTIVE_FLAG (partition key)
CLIENT
GROUP_ID (PARTITION BY FK TO GROUP)
ACCOUT
GROUP_ID (PARTITION BY FK TO GROUP)
CLIENT_TO_ACCOUNT
GROUP_ID (PARTITION BY FK TO GROUP)
The issues I am seeing right now:
1. Graphs(groups) may be potentially unlimited, so I will need a artificially limit the size using some dividing algorithms - leading to
2. Graphs(groups) may need to be joined or divided
3. Graphs(groups) will have to be activated/deactivated - e.g. moved to different partitions.
4. Data loading, activation/deactivation algorithms are not simple
So I am thinking about Oracle Spatial (Network) to model this problem.
Questions:
1) Can I model this problem using Oracle Spatial?
2) Will I gain any performance improvement?
3) Is there any explanation or white paper on how to do this for this particular type of problem?
4) Will the solution based on Oracle Spatial solve the problems outlined above?
5) Will my solution (without using Oracle spatial) work at all? Or there are some fundamental issues..
Thanks you!

Either add a LOV to the JobID attribute definition in the VO (if the JobID will be editable) or simply add the job description to the select statement (join to the job table) as a reference attribute

Why should I use SQLJ

Why should I use SQLJ instead of JDBC, is it for faster Acess than JDBC, or for any other reasons

Why should I use SQLJ instead of JDBC, is it for
faster Acess than JDBC, or for any other reasonsJust guessing...
It should be faster - but you should test.
I would suspect that it is going to be harder to maintain because it is less used (thus less tested), less known (so harder to hire people to maintain) and less 'standard' (thus figuring out what went wrong can be harder.)

Why should I use xinetd?

Im using inetd, but in mandrake I had xinetd, and somewhere I had read that it is better. Is this true?, and if so, ahow do I install it, cause it's not in pacman (i know I cant install it from source, but I wonder if it's hidden somewhere in the distro)

http://www.xinetd.org/faq.html
Q. What is xinetd ?
A. xinetd is a replacement for inetd, the internet services daemon.
Q: I am not a system administrator; what do I care about an inetd replacement ?
A: xinetd is not just an inetd replacement. Anybody can use it to start servers that don't require privileged ports because xinetd does not require that the services in its configuration file be listed in /etc/services.
Q. Is it compatible with inetd ?
A. No, its configuration file has a different format than inetd's one and it understands different signals. However the signal-to-action assignment can be changed and a program has been included to convert inetd.conf to xinetd.conf.
Q. Why should I use it ?
A. Because it is a lot better (IMHO) than inetd. Here are the reasons:
1) It can do access control on all services based on:
a. address of remote host
b. time of access
c. name of remote host
d. domain name of remote host
2) Access control works on all services, whether multi-threaded or single-threaded and for both the TCP and UDP protocols. All UDP packets can be checked as well as all TCP connections.
3) It provides hard reconfiguration:
a. kills servers for services that are no longer in the configuration file
b. kills servers that no longer meet the access control criteria
4) It can prevent denial-of-access attacks by
a. placing limits on the number of servers for each service (avoids process table overflows)
b. placing an upper bound on the number of processes it will fork
c. placing limits on the size of log files it creates
d. placing limits on the number of connection a single host can initiate
e. place limits on the rate of incoming connections
f. discontinue services if the load exceeds specified limit
5) Extensive logging abilities:
a. for every server started it can log:
i) the time when the server was started
ii) the remote host address
iii) who was the remote user (if the other end runs a RFC-931/RFC-1413 server)
iv) how long the server was running
(i, ii and iii can be logged for failed attempts too).
b. for some services, if the access control fails, it can log information about the attempted access (for example, it can log the user name and command for the rsh service)
6) No limit on number of server arguments
7) You can bind specifc services to specific IP's on your host machine

Why should I use EJB

Hi,
My name is Gandharv Sirohi. I am a student, and new to EJB. I want to know why should I use EJB, before I can start learning it if every thing can be done using Java Servlets and JSP.
I tried to find out the answer to this question in books but there is no satisfactory answer.
Can some body help me understand this simple question. I will be thankfull

Hi gandharv,
It's true there are a lot of services available to both the web tier and the EJB tier. One of the
real strengths of EJB is support for transactional business logic. Web components can
explicitly demarcate transactions via UserTransaction, but container-managed transaction
support in EJB components at the business method level offers a much simpler approach
for developing and maintaining such applications. An example of some EJB services not available
in the web tier are : method-level security, RMI-IIOP access, message-driven beans,
transactional/persistent timer service, stateful components, extended container-managed
persistence contexts, guaranteed single-threaded execution, and interceptors.
Of course there are many services available to the web tier that are not in EJB. It's not
about picking one of the two that should always be used. Like any tool/technology, each has its strengths, weaknesses, and design center.
