How to check the database existence using java.

Hi All,
I need to know if a database exists or not using DB2 sql statements. Is there any sql to find that.
Thanks in advance

try to connect to the database. if it is possible, the database exists - if not - well there may be a number of reasons, but if your database URL is correct, your network is ok and your database engine is running, the database is not existent.

How to check the database connection using OCI

I am working on enhhancement of very old application developed using C and OCI. It has a background process which acts as a middleware for interaction of any other front end process with oracle database. Any processes, which needs to interact with database sends a request to background peocess and then it will execute a call to execute the stored procedures for performing requested operation (like select, update, insert) on table and will send the result back to respective process. So this process has to be always running in background and connected to branch database.
If branch database gets restarted or connection gets dropped due to some ad-hoc problem then the background process also has to be restarted manually. Because this process establishes the connection to branch database only once on start up and it does not have the intelligence to reconnect automatically in such scenario.
I am looking forward to build the intelligence in this process to automatically reconnect if connection with branch database is lost. But I am not familer with OCI, and I am not sure if there is any OCI call which can determine if my earlier connection is still available. Can any one please tell me if there is any other way to check the connection other than the execution of dummy query, then check if it gets executed properly and then do the actual query.
Thanks in advance,

Hi,
If you are reworking the application can you not build in the functionality to re-establish a connection if there is a failure? That is, a submission from the application server to the database server detects a failure, etc. and then re-establishes the connection. If you need a more frequent check than during a user-initiated roundtrip, you may be best served by using the "dummy query" technique on some time interval.
From my understanding using HA Event Notification would require a RAC database (plus a multi-threaded application and services correctly configured on the RAC-side).
In the documentation I see this:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14250/oci09adv.htm#sthref1495
"Applications must connect to a RAC instance to enable HA event notification."
In any case, this has the potential to be a bit complicated...

In ecatt - how to check at database level using ABAP

Hi,
How to check at database level using ABAP in Ecatt tool.
say,for example I want to check a particular sales order is invoiced or not ,at the database level and if it is invoiced I have stop proceeding to invoicing of that sales order number.
Could anybody suggest on this with an example?
thanks.

Hi,
you can use the command GETTAB to access single db records.
Full specified or partitial specified keys can be use at GETTAB. It will return always only one record, also if a couple could match your selection.
For more advanced scenarios you can also use eCATTs Inline ABAP. In a block between the commands ABAP. ENDABAP. you can code ABAP statements, e.g. SELECT ... INTO TABLE ...
eCATT script parameters of type 'V' defined in that script using ABAP/ENDABAP will be transfered into the ABAP block and back to script after ABAP perform.
Best regards
Jens

How to connect the database (JDBC) using service name rather than SID

How should we make the connection to the database using service name. Initially, we are using the SID to make the database connection, with following setting in the data-source.xml in OC4J using ABCDB as the SID.
<data-sources>
     <data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="jdbc/ABCDB"
          location="jdbc/ABCDB"
          pooled-location="jdbc/OracleDSPooled"
          xa-location="jdbc/xa/OracleDSXA"
          connection-driver="oracle.jdbc.driver.OracleDriver"
          username="ABC"
          password="ABC"
          url="jdbc:oracle:thin:@191.1.4.126:1521:ABCDB"
     />
</data-sources>
It work, but now we need to make the connection using this service name ABCSERVICE, but it doesn't work in the OC4J (JDBC). May I know how should we handle this connection?
Thanks and Regards,
Pang

Finally, I got the solution to make the database connection using service name, with putting the tnsname setting in URL portion.
url="jdbc:oracle:thin:@(description=(address=(host=191.1.4.126)(protocol=tcp)(port=1521))(connect_data=(SERVICE_NAME = ABCSERVICE)))"
And now, it is working fine.

How to check the material consumption using tables

Hi,
I would like to know how to generate or view the material consumption at table level. Can anyone please specify the transactions codes and tables names how to check the consumption of material. I also like to know how to analysis the consumption of material between components and finished material. Please provide me the step by step wise how to do.Thanking you
Regards,
Sivaji Kumar Madhu Kiran

You can calculate material consumption in table MSEG. you will need to segregate the material documents based on movement types and then add or reduce the quantities of each material document. for example a material document with movement 101, add the quantity for the material, and when there is a issue material document like 201 or 221 reduce the quantity from the material stock.

Hi,
You might want to check the JCDK user guide (cJDK_Users_Guide_bin_do.pdf) for details of using an emulated card environment. It outlines how to use the simulators provided with the JCDK. This should tell you how the deploy process works and will give you some insight into what this script is doing.

How to disconnect the database connection using crystal report

Post Author: cp_pramodu
CA Forum: Crystal Reports
Hi All,
We have developed an application using .Net and Crystal Reports 10 for generating Adhoc reports from Business system (db sybase 12). We are using the below mentioned script for opening rpt files.
Try
       ReportDocument1.Load(sReportName)
       For Each table In ReportDocument1.Database.Tables
              ' Get the TableLogOnInfo object.
              logonInfo = table.LogOnInfo
              ' Set the server or ODBC data source name, database name,
              ' user ID, and password.
              logonInfo.ConnectionInfo.ServerName = sReportServerName
              logonInfo.ConnectionInfo.DatabaseName = DBName
              logonInfo.ConnectionInfo.UserID = UserName
              logonInfo.ConnectionInfo.Password = Password
              ' Apply the connection information to the table.
             table.ApplyLogOnInfo(logonInfo)
Next
'Me.Cursor = Cursors.WaitCursor
Me.CrystalReportViewer1.ReportSource = ReportDocument1
'Me.Cursor = Cursors.Default
Catch ex As Exception
'Response.Write(ex.Message)
Finally
Me.Cursor = Cursors.Default
'ReportDocument1.Close()
'ReportDocument1.Dispose()
End Try
Each time user opens the report a new connection is established to the database, can we disconnect the connection established from crystal reports, while closing crystal report. At the same time i want to setup an Idle time for these connections. In database level, i will not be able to set idle time in database level, as it affect our electronic channels.
Waiting for a reply.
Thanks & Regards,
Pramodu. C. P

How to check the database is running in which normalization

All,
I wanted to know in which normal form(1NF,2NF,BCNF) my database is working. How to find that...Suggestions Please .

Tippu, I will agree with pretty much everything that the other posters have already posted.
Related to the concept of normalization, in the database would be the definitions of primary key (PK), unique key (UK), and foreign key (FK) constainsts within the database. Looking at the constaints definded in the database by querying the rdbms dictionary view DBA_CONSTRAINTS might be of interest for trying to identify and understand the relationship between tables in your applications. However, there is no database requirement that these relationships be defined within the database.
That is instead of declaring a PK on tableA there might just be a unique index and no FK to the header table, tableA, from its child detail table, tableB, declared in the database in this case. It would be totally up to the application to enforce this relationship. Still the view will provide information if most of the table relationships are formally defined in the database or not.
