Nobody knows whats the table is for....
Actually we were working with oracle 7.3 upto 2004. On 2004 we upgraded to 9iR2. May be the DBA in that time made some mistake.... i think so....thats why all these tables are still here....
I was not in the picture during that time.
Now my question is how can i know whether this table is necessary or not. I asked the developers here they said they are not using these tables. But my manager is afraid to delete these tables.
now what should i do?

Hi,
Yet another request to use my crystal ball.
We had one pc which is having oracle 9i enterprise manager configured(windows 2000) only to connect the db.
This remembers me of the Gospel of St. Luke, chapter 2, where it is stated,
'and they found the child in the manger'.
This resulted a Jewish theologian to remark: 'The manger? Well, so that must have been their own manger'
So what does 'the' db mean? The Linux one? Or a separate on Win2000?
It is quite possible to manage a Linux database using OEM on Win2000, with OMS on Win2000.
'But our server is not having enterprise manager'. Yet another riddle. Which server? There seem to be at least two.
1 Now if I drop these tables, will I be able to connect to our database using the windows2k pc through Enterprise Manager?
Yes, but only in standalone mode, and you can't use OEM alerts, and jobs anymore. You would be better off using Sqldeveloper, as OEM Sql worksheet is a nightmare.
2 That is your decision.

oemctl ping oms
will check whether you have an Oracle Management Server running.
You already seem to have the Enterprise Manager Repository, so you must have OMS running somewhere. (Why install the repository, if you don't use it)

How to find whether the patch is applied or not in SOA?

Dear Legends,
I need to find a given patch(13615085) is applied or not in SOA Environment(RAC). I do not have O/s Level access, so I cannot issue Opatch lsinventory.
I tried
select * from dba_registry_history; - nothing is displayed.
Thanks in Advance,
Karthik

To check patchs installed:
From Opatch
$ORACLE_HOME/Opatch> opatch lsinventory
From sql
select * from dba_registry_history;
*To execute Opatch you don't need root privileges, you can also do it from oracle user
If you don't see anything executing "select * from dba_registry_history;" You haven't any patch installed.

How to find whether remote database is up or not (connected via dblink)

Hi,
I am using dblink to connect Biz database from Dev database.(Biz, Dev - database names)
Running dbms job using the dblink from the Dev database to update data on Biz database...
Problem is dbms job should run if and only if the Biz database is up for which i created the dblink...
1) How to make sure or implement the check to find whether the Biz is database is up or not in Pl/sql or sql...
2) How to reschedule the dbms jobs once the database is up
pls suggest me how to find whether the database is up or not b4 running the dbms job?
Using- Oracle 10g

The only way to know whether the remote database is up (and whether the network between the two databases is up and whether the remote database's listener is up and whether the password configured in the database link is correct and whether the local TNS alias is correct, etc) would be to actually run a query against the remote database over the database link. In other words, the way to figure out whether the link is up is to let the job run and catch & handle exceptions when there are problems.
By default, a job scheduled via DBMS_JOB will automatically reschedule itself if there is an unhandled exception by geometrically backing off (it waits 1 minute after the first failure, 2 minutes after the second, 4, 8, 16, 32 minutes, etc until it's marked as broken after 16 failures). You could, of course, catch appropriate exceptions and handle them in a reasonable fashion and manually reschedule jobs at intervals that make more sense for your particular job.

How to find all the tables associated for a particular transaction

Hi-
May I know how to find all the tables, related(foreign key) tables for a transaction within SAP GUI?
Up to my technical knowledge, this can be achieved by looking database diagrams from DB level. But that would be for entire database as a whole. What I'm expecting is to see transaction level relative tables that too from SAP GUI. Please share the possibilities if any.

Sekhar

Dear Micky Oestreich
May be we possess expertise or high level experience, it should not show up in our way of communication. Every professional starts with the basic stuff to learn. When the question is raised in such minimum polite way, the same level of courtesy is expected in return. If you felt my question was basic, you might have refused it gently. If you are in good mood or bad mood it doesn't matters.

Thanks for your response. It helped me.

Hi guys,Explain how to find whether the user request is dialog or bc ...

how to find whether the user request is dialog or bc or some other wp and where we can see that ?

Hello Damodar,
You can find out that in SM50.
However one piece of advice. I have noticed that you are raising lots of questions about very basic questions. Either you new to SAP or dont know anything about SAP Basis and want to get in this area. Or else you are preparing for some interview. In either of these cases expecting solutions given at SDN are not going to be of much help. Better read yorself in SAP Help as most people do. SDN should not be overly used for such purposes. Basic questions are welcome but you want to learn SAP through SDN !!!

Hi Ravi,
To find out all tables used go into the CRM source system to transaction RSA3 and prepare the selections for extraction of your datasource.
In a parallel session execute transaction ST05 and press the button 'Activate Trace'
Go back to the extracor checker and execute the extraction.
Switch sessions and subsequently 'Deactivate Trace' and 'Display Trace'.
This will list all tables used.

How to know whether the javascript is disabled or not while loading the jsp

Hi,
My query is like how to know whether the javascript is disabled or not while loading the Application main JSP in Mozilla browser.
I want some Java code or JavaScript code.

To the point, just let JS fire a specific HTTP request inside the same session.
This can be done in several ways. 1) Create a hidden <img> element and set the `src` attribute so that it will request a (fake) image from the server. The server just have to intercept on this specific request. 2) Fire an ajaxical request and let the server intercept on it. You can use a Filter for this which sets a token in the session scope to inform that the client has JS enabled.

How to know whether the tables in function module is importing or exporting parameter?

Hi guys,
Why the tables are used in function modules, I knw it transfers internal tables, but thing is that how would i know instantly that whether table is getting imported or exported to the funtion module? Do i need to go through program flow or can we know just by seeing the function module?

Hi anjali,
Tables are like multi line containers ,which can act as both import and export parameters .
means,the data in the table can be used by the function module during its execution and the same table can be populated with result after the fm execution .
you can also refer :http://help.sap.com/saphelp_erp60_sp/helpdata/en/d1/801ece454211d189710000e8322d00/content.htm

Hi Raj
Function Modules
Function modules are procedures that are defined in special ABAP programs only, so-called function groups, but can be called from all ABAP programs. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the SAP System. They are managed in a central function library. The SAP System contains several predefined functions modules that can be called from any ABAP program. Function modules also play an important role during updating and in interaction between different SAP systems, or between SAP systems and remote systems through remote communications.
Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the Function Builder. The actual ABAP interface definition remains hidden from the programmer. You can define the input parameters of a function module as optional. You can also assign default values to them. Function modules also support exception handling. This allows you to catch certain errors while the function module is running. You can test function modules without having to include them in a program using the Function Builder.
The Function Builder also has a release process for function modules. This ensures that incompatible changes cannot be made to any function modules that have already been released. This applies particularly to the interface. Programs that use a released function module will not cease to work if the function module is changed.

You can execute function module in SE37ie you can perform the activiites defined in the function module by executing it.
By deleting BOM you mention the FM name in se37 and execute. In some function module it will ask input parameters as developed in the program , you have to give the input parameters and execute.
