Other Data Base Access in BSP

Dear All,
Is it possible to make the BSP application to communicate with other DataBases like SQL , Oracle?
Kind Regards,
Mukesh

Hi,
As long as you can do it using ABAP !
You can use transaction DBCO for this.
Here are some helpful links

Data base access time

Hello all,
I have following scenario:
1) I have one select query which is fetching 5,000 records from data base in single select.
2)Two select query from the same table fetching 1,000 records each time.
I want to know that which option will take more time that is 1 will take more time or 2.
Thanks and regards
Sachin

Hi Sachin,
The second selection query will take more time beacuse it has to hit the data base 2 times and also increases traffic on database server hence it takes more time .
and second selection query may take 4 to 5 times of first selection query.

Data base Access

Hi
I am developing a PDK (java) application
From my application i need to get data from .Net system
What are all the possible ways to access data from .Net System
Thanks
Rudra

When you say .NET System what do you mean? Is that an MS SQL Server, a Sharepoint portal, other .NET system....?
There are many ways to access database.
In my opinion the most recommended one is using EJB or Hibernate because that gives you real MVC seperation, but it will be a bit difficult to implement in a PDK application.
The quickest way will be using JDBC: Either configure the connection on the app server and access it's alias using the Initial context object or create the JDBC connection in your code but I highly recommend configuring it on the app server.
Once configured, you can use something like that to access the object:
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup(<YOUR_ALIAS>);
Connection conn = ds.getConnbection();
Hope it helps,
Roy

OC4J data-source.xml other data base like postgresql

Hi i need to use a DataSource in OC4J with other database (any), i am setting the data-source.xml like:
<\datasource
class="com.evermind.sql.DriverManagerDataSource"
name="DSPropiedades" location="jdbc/DSPropiedadesCoreDS"
xa-location="jdbc/xa/DSPropiedadesXADS"
ejb-location="jdbc/DSPropiedades"
connection-driver="com.borland.datastore.jdbc.DataStore"
username="sample"
password="sample"
url="jdbc:borland:dslocal:D:/seguridaddb/seguridad.jds"
inactivity-timeout="300"
/>
and i had put the database.jar in the OC4j directory's
D:\ora10i\jdbc\lib
D:\ora10i\j2ee\home\lib
D:\ora10i\lib
but i always obtain the same error
Error initializing data-source 'jdbc/DSPropiedadesCoreDS': DriverManagerDataSource Driver 'com.borland.datastore.jdbc.DataStore' not found

Liliana,
From the [lack of] information you have posted, I am assuming you are using OC4J stand-alone version 10g -- but I'm not sure because I couldn't find any of those details in your post. It always helps to include version and platform information.
If my assumption is correct, then the default location for third-party JAR files (including your JDBC driver) is the
"j2ee/home/applib"
subdirectory of the OC4J installation. For example, on my Windows XP machine (again, I couldn't see what platform you are using, so I am assuming it is also Windows), the actual path is:
C:\OC4J_10_0_3\j2ee\home\applib
If you want to see other examples of "data-sources.xml" files (apart from the one that comes with OC4J), try searching the following Web sites:

Good Luck,

What is logical data base and how it is differfrom DDIC AND DATABASE

HI ,
CAN ANY BODY HELP ME TO FIND THIS

Hi
A logical database is a special ABAP/4 program which combines the contents of certain database tables. You can link a logical database to an ABAP/4 report program as an attribute. The logical database then supplies the report program with a set of hierarchically structured table lines which can be taken from different database tables.
LDB offers an easy-to-use selection screens. You can modify the pre-generated selection screen to your needs. It offers check functions to check whether user input is complete, correct, and plausible. It offers reasonable data selections. It contains central authorization checks for data base accesses. Enhancements such as improved performance immediately apply to all report programs that use the logical database.
Less coding s required to retrieve data compared to normal internel tables.
Tables used LDB are in hierarchial structure.
Mainly we used LDBs in HR Abap Programming.
Where all tables are highly inter related so LDBs can optimize the performance there.

Logical data base

hi experts!!
i am working on the LDb report and i have created a LDB zaxxx in se36 and using the same LDB to code in se38 and in attributes i have mentioned the name of LDB.
when i code follwoing:
GET ZAXXXX FIELDS INVOICE_NUM CUST_NAME CUST_PO_NUM INV_DATE.
ITS GIVING ERROR THAT ZAXXX IS NOT SPECIFIED FOR FIELD SELECTION.
when i use only
GET ZAXXXX . when i debug valuse are comming but when process the report its giving no valuse.
plz suggest me on the same..

Creating a Crystal Report from a non-SAP data base

I have the following scenario
server1\myDataBase
server1\SAP\sapDataBases
in sapDataBases I have about 30 company databases. I am trying to create a report, that gets informatino from a table/view/SP from server1\myDataBase, when I try to PREVIEW or SAVE such report on SAP Business One, I always get errors as
I understand that this eerror means taht I can't invoke the data from out of SAP; it needs to be inside SAP (at least the SP, incoking some other data bases and stuff..)
Some bodies have told me that it is beacuase I can only create a report from a table/view/sp that resides in the running/currently SAP company database. Is this right?
Also, If this is the case, this means that If I have an SP taht I use for a crystal report, and 30 companies, I have to create such SP in the 30 companies?
This is my software details:
SQL Server 2012
SAP Business One 9 PL 11
SAP BusinessObjects Crystal Reports 2013 Support Pack 2 version 14.1.2.1121
What I want to do is to create a non-SAP data base to create all the SPs/Views for reports, to centralize it, and the just create one reporte and do the 30-imports in each company database, without the need of creating such sps/views in each company-database. Is this possible?
Thanks

Moved to Integration Kit forum.
The people in this forum will know more about the data structure than the CR Design forum which typically doesn't know much about the SAP Data sources Structure.

EJB- data base connectiviy:

we used Jdeveloper 3.0 to develop a Simple EJB object using the wizard.
we have also deployed the same in the oracle 8i data base(8.1.5).
there were no errors during deployment.
we used jdk 1.1.8 option for developing EJB objects.
we have also created a EJB client using JDveloper Wizard.
client is also working fine when we invoke the EJB object .
In our bean class we are using JDBC calls for validation:
we used the following code in the bean class in our method for getting connection:
Connection conn = new oracle.jdbc.driver.OracleDriver().defalutConnection();
with this connection we executed JDBC calls.
the client is able to establish a data base connection .and able to invoke our bean method also.
Here the data base to which we connect is same where we deployed our EJB object.
(the deployement and JDBC calls are made to the same data base )
Now we try to use the following code for connecting to the data base other than where we deployed the EJB object.
The data base from where we try to establish data base conncection is oracle 8.0.4 . (for business logic )
we use the following code in our bean class for the data base connection
Class.forName("oracle.jdbc.driver.OracleDriver");
String url = "jdbc:oracle:thin:@192.168.1.99:1521:orcl"
Connection conn = DriverManager.getConnection( url,"pilotjava","insyst");
when we run the clinet it is giving following error message

Best Practice for SAP PI installation to share Data Base server with other

Hi All,
We are going for PI three tire installation but now I need some best practice document for PI installation should share Data base with other Non-SAP Application or not. I never see SAP PI install on Data base server which has other Application sharing. I do not know what is best practice but I am sure sharing data base server with other non-sap application doesnu2019t look good means not clean architecture, so I need some SAP document for best practice to get it approve from management. If somebody has any document link please let me know.
With regards
Sunil

You should not mix different apps into one database.
If you have a standard database license provided by SAP, then this is not allowed. See these sap notes for details:
[581312 - Oracle database: licensing restrictions|https://service.sap.com/sap/bc/bsp/spn/sapnotes/index2.htm?numm=581312]
[105047 - Support for Oracle functions in the SAP environment|https://service.sap.com/sap/bc/bsp/spn/sapnotes/index2.htm?numm=105047] -> number 23
23. External data in the SAP database
Must be covered by an acquired database license (Note 581312).
Permitted for administration tools and monitoring tools.
In addition, we do not recommend to use an SAP database with non-SAP software, since this constellation has considerable disadvantages

Itunes 6 does not access the cddb gracenote data base any more

i have installed norton products, but changing the setting does not affect the status, i could not successfully update to itunes 6+ and the girl from apple said it has no major upgrade in it, but my grace note data base does not work any more, i get a yellow triangle and problem with http and stuff, so i changed to winamp for filing my music, though i believe, sound wise, itunes might be slightly better, but winamp is consumer friendly and whiskey bernstein in my case, the "momo" time thief gray of itunes is not a turn on, so does any one know what can happen to the cddb data access ? merci, henri

There are no duplicate items.
If you want to listen to a song on your iPhone and also on your iPod, you have to have a copy in each library.
You just tick sync all songs in each library then tick/untick each song as necessary for each library.
I never uncheck anything.
I just add/delete from a playlist and sync.
How the **** do we now know which library we are in???
You know which **** library you are in because it is the one you **** well opened.
If you only use one library, there is no wondering which library you are using.
Any way, good luck!

How to access two oracle data base with out DB link

Hi,
I have two data base schema
one is held in oracle 10g and the other in 11g ,Currently i am using DB link to access both the database. i am accessing around 70 tables using DB link.

The target database can implement PL/SQL web services. These can be called via HTTP.
The local database can use UTL_HTTP to make a call to the target database's web service for accessing target database data.
Both databases can use AQ (Advance Queues). This can be integrated with an application server's JMS queues.
This enable one database to enqueue a request to the other database, and for that database to respond by sending data.
There are numerous such type of interfaces that can be used. Some primitive. Some advanced. Some simple. Some complex.
The easiest and most flexible mechanism is however a database link. And it does not make sense to disallow database links for security and management reasons, but allow JMS for example. The network infrastructure is the same for both methods. The network protocol is the same. The security issues and concerns are the same - except that JMS for example is significantly more moving parts and make configuration and security a lot more complex than using a database link.

Access non-Oracle data base from Oracle Data base?

Hi,
I have a system using Oracle data base but i have to query some data in
Access data base called TA_2008.mdb for specific table called FPTrans
My oracle database SID=Ahmed10g my schema is attend/attend.
I have tried to use the Heterogenous Services Generic Connectivity Agents .
I think i have to build the ODBC driver for Access database not for oracle and specify the Access DB name
But i built the driver for oracle.
Please clear the steps for me and correct me if i am wrong .......................
1. Create ODBC driver [microsoft ODBC for Oracle] as File Data Source Name =attendoraclefds
user : attend
password : attend
Server :ahmed10g
2. create intilization Parameter file in the path D:\oracle10gDB\product\10.2.0\db_1\hs\admin
called : initATTENDORACLEFDS.ora
CONTAINS PARAMETERS:
HS_FDS_CONNECT_INFO=FILEDSN=attendoraclefds
HS_FDS_TRACE_LEVEL=ON
3. Edit TNSname.ora file :
attendoraclefds =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = awahaishi_lptp.sepocye.com)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = attendoraclefds)
(HS = OK)
4. Edit Listener.ora file :
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =

a question about transparent gateway,sb help me plz!!

Since Apple's data base has been accessed by burglars, why can't Apple track serial numbers?

If Apple's data base is accessed by people like this, why can't the same data base be used to track ownership? MOst Apple users sign on to itunes and share their system information. Would it not make sense to share the serial numbers with a reporting system?
If I call into the local Apple store, will I receive any support in locating my systems or will they want to sell me an app to track them?
The data is available for Apple to promote an independent recovery sytem...why don't they? Is there no money in it?

why can't the local Apple store access the national data base and find out where it was being serviced.
They can do that now, if the system is at an authorized service center. It's highly unlikely that a stolen system would just happen to have been checked into a service center at the time you happen to look, though. I also doubt that Apple would provide that information to you just on your request.
As to the report you are referencing, is it coinicidence homes with multiple Apple systems were targeted? In my neighborhood, only homes with more than two Imacs were hit...and only Apple systems were taken.
Such information would not be available to any burglar, nor has there been even a rumor that Apple's internal customer databases have every been compromised. So yes, it was either coincidence or the burglars casing the premises, not at all hard to do. It's even often possible by doing a scan of someone's WiFi network; few people have theirs adequately secured.
Apple is not law enforcement. It's not their job to try and track stolen property; that's the job for the police. There's nothing further to be said.
