Hai,
Iam currently logged onto oracle without any DBA privileges and want to know the database name. Please let me know how can i find it.
Thanks.

if u have "Select Any Table" privilege to your database user in which u logged in then fire the below query.

Getting the table names in an MS Access database

Hi,
I am new to JDBC and making a client/server application that updates a MS Access database through jdbc:odbc.
I need to get a list of existing user tables in the db. I have found a great document on the net which has the code, however the code doesn't work. I have tried different ways and looked every where with no success. (link to the doco: http://www-128.ibm.com/developerworks/opensource/library/j-jdbc-objects/)
Here is my dbManager class that handles all db related services in my application. I would appreciate any help I can get as I have exhusted all my avenues.
Thanks

How to get the database owner name in T-SQL script

Hello, All!
I want to get the database ower name (in format DOMAIN\user) by through T-SQL script. But SELECT * FROM sys.databases returns only owner_sid.
Please show me a way - how to get the owner name, if you have only owner_sid. Or, may be, somebody know another way ?

Problem in getting the database connection from a connection pool

Hai All,
I am facing a problem in getting the database connection from a connection pool created on weblogic server 8.1.
I am using the Oracle database 8.1.7.
I have configured my connection pool, datasource and JNDI in weblogic.
In my java program i have the following code to retrieve the connection.
import java.sql.*;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
class jdbcshp1 {
    public static void main(String[] args) {
     Connection connection = null;
     try {
           Hashtable ht = new Hashtable();
           ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); // Wanna get rid of this.
           ht.put(Context.PROVIDER_URL,"t3://localhost:7001"); // wanna get rid of this.
           // Get a context for the JNDI look up
           Context ctx = new InitialContext(ht);
        javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("myjndi1");
          //Create a connection object
          connection = ds.getConnection();
     The above code is working fine but, the two ht.put statements are creating problem.
The problem is, after converting the application into WAR file it can be deployed
on any machine or different port on same machine. My application fails if its deployed on
weglogicserver which is at different port.
Is there any way that i can get rid of those ht.put statements or any other way to solve the problem.
any help is appreciated.
Thanks in advance
Pooja.

Hai All,
Firstly, thanks for ur reply.
Even i have seen some code which uses context constructor with out any parameter and works fine.
i dont understand why its not working for my code.
When i remove those ht.put code and use context constructor with out any parameter, it giving an error.
Context ctx = new InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("ocjndi");
connection = ds.getConnection();The error is as follows:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
the above error is forcing me to include those code but if the port number is changed the code will not work. Plz let meknow if some setting have to be made.
I appreciate all ur valuable help.
Thanks once again.
Pooja.

How to get the table name of a field in a result set

hi!
i have a simple sql query as
select tbl_customerRegistration.*, tbl_customerAddress.address from tbl_customerRegistration, tbl_customerAddress where tbl_customerAddress.customer_id = tbl_customerRegistration.customer_ID
this query executes well and gets data from the database when i get ResultsetMetaData from my result set (having result of above query) i am able to get the field name as
ResultSetMetaData rsmd = rs.getMetaData();//rs is result set
String columnName = rsmd.getColumnName(1);
here i get columnName = "Customer_id"
but when i try to get the tabel name from meta data as
String tableName = rsmd.getTableName(1); i get empty string in table name....
i want to get the table name of the respective field here as it is very important to my logic.....
how can i do that.....
please help me in that regard as it is very urgent
thanks in advance

So far as I'm aware, you can't get metadata information about the underlying tables in a query from Oracle and/or the Oracle drivers. I suspect, in fact, that the driver would have to have its own SQL parser to get this sort of information.
I'm curious though-- how do you have application logic that depends on the name of the source table but not know in the application what table is involved? Could you do something "cheesy" like
SELECT 'tbl_customerRegistration' AS tbl1_name,
tbl_customerRegistration.*

Getting the file name using ehdr:getRequestHeader function in style sheet

Hi, I am facing an issue while using ehdr:getRequestHeader function to get the name of the file, which was placed in FTPS server and read by FTP Adapter. In style sheet I am trying to get the file name as below.
<xsl:variable name="fileName"
select="ehdr:getRequestHeader('/fhdr:InboundFTPHeaderType/fhdr:fileName','fhdr=http://xmlns.oracle.com/pcbpel/adapter/ftp/;')"/>
and based on the file name I am trying to fetch the values from Property file, map it to a schema and make a SOAP service call.
When i use the above functionality in style sheet exception occurs and in ESB instance I am not able to view the exception.
It is saying as 'Details of the message are not available, The message details would have been purged'. In logs it is showing the following error trace.

When I use the same function getRequestHeader for FileAdapter, it is working fine. Do anyone know why this issue occurs? Is this an issue with environment?

As far as I can see the problem is the invoke of the SOAP service. This could be because of an empty filename but maybe there are other issues. First, make sure that the filename is read correctly by looking it up in the BPEL runtime process. Maybe the content is different than you expected it so that the read action for the properties give wrong result. Are you sure that ehdr is the correct prefix for the ftpheader?

How to get the real name of a user from WFSYST-AGENT

Hi,
I am retrieving the WFSYST-AGENT value (which correspond to the US<user_id> of the agent responsible of a task) in a container variable in my workflow.

Set the DB_NAME initialization parameter in the initialization parameter file (PFILE) to the new database name.
Note:
The DBNEWID utility does not change the server parameter file (SPFILE). Therefore, if you use SPFILE to start your Oracle database, you must re-create the initialization parameter file from the server parameter file, remove the server parameter file, change the DB_NAME in the initialization parameter file, and then re-create the server parameter file.

Reading csv file how to get the Column name

Hi,
I am trying to read a csv file and then save the data to Oracle.
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection c = DriverManager.getConnection("jdbc:odbc:;Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=.;Extensions=csv,txn");
Statement stmt = c.createStatement();
ResultSet rs = stmt.executeQuery("select * from filename.csv");
while(rs.next())
System.out.println(rs.getString("Num"));
My csv file looks like this:
"CHAM-23","COMPANY NAME","Test","12",20031213,15,16
Number,Environ,Envel,Date,Time
"1","2",3,"4",5
"6","7",8,"9",9
Now is there anyway using the above code I start processing the file from the second row that holds the names of the columns and skip the first row. And also can I get the name of the column using ResultSet something like:
if columnName.equals("Number")
Because I may have a csv file that could have more columns:
"CHAM-24","COMPANY NAME","Test","12",20031213,16,76
Number,Environ,Envel,Date,Time,Total,Count
"1","2","3","4","5",3,9
"6","7","8","9",9",,2
So I want to get the column name and then based on that column I do some other processing.
Once I read the value of each row I want to save the data to an Oracle Table. How do I connect to Oracle from my Application. As the database is on the server. Any help is really appreciated. Thanks

The only thing I could think of (and this is a cluj) would be to attempt to parse the first element of each row as a number. If it fails, you do not have a column name row. You are counting on the fact that you will never have a column name that is a number in the first position.
However, I agree that not always placing the headers in the same location is asking for trouble. If you have control over the file, format it how you want. If someone else has control over the file, find out why they are doing it that way. Maybe there is a "magic" number in the first row telling you where to jump.
Also, I would not use ODBC to simply parse a CSV file. If the file is formatted identically to Microsoft's format (headers in first row, all subsequent rows have same number of columns), then it's fine to take a shortcut and not write your own parser. But if the file is not adhering to that format, don't both using the M$ ODBC driver.

Can you get the file name of the current executing TSQL script?

Can you get the file name of the current executing TSQL script? I wrote entries to a generic log file and would like to include the script name.

Okay, So What you can do is
1. Read get the version from your database and redirect it to a text file(SQLCMD outout can be directed to text file using -o option or windows redirection operator >)
2. Now you can read this value from the text file either inside a batch file or a powershell script and decide what operations you can do.

How can I use JDBC to get the db name in a db url ?

Hi,
My program needs to read a database url from a txt file and connect to the specify database. And my program also needs to know what's the database name. So DatabaseMetaData or Driver can retrieve the database name from the url ?
Please brief me about that.
thank a lot.

You need to write a java program to read the text file with buffered streams. Then you need to use this file as a bean.
In the same file you can have connection to your database.
get theconnection and related things in your web application.

How to modify the database name

Hi people
Im a developer and it's the first time that I use the Xe version of oracle. I need to modify the database name but I don't know how to make this. Im finding the commands but I don't meet this.
Anyone can help me?
Thanks
Best Regards

Hi,
XE is XE is XE ... ;-)
If you'd like to rename it you may get a database license for at least a STANARD EDITION ONE database, upgrade your XE to SE-ONE and then rename your database.
But (as it has been noted before) for obvious reasons there's no way to rename an XE database to something else :-)
Kind regards
Mike

Agreed, but IMO, i still feel its best if there is no tie in between consumer class level details and the database it talks to. A service layer is needed in between them.Sounds like you've done a bit of this before. Me, I've either been a modeller/DBA, doling out data, or a nuts and bolts programmer (and actually more toolmaker than apps, but did a bit of that too).
Do you know of a good book about the "middle ground" (ie, these service layers)? I understand it empirically, but haven't had a lot of exposure to it.

PS: Apologies. Edited my previous post, presumably while you were composing your reply, when I finally realized what '.filed' meant.Most of my work is in web development, never been a DBA :) . The biggest 'concern' in my shop is 'separation of concerns'. The UI group reports up to a different IT head, the DB group reports up to a different IT head and so on. The looser the coupling between these systems, the lesser the project costs (Integration, QA etc) are. Martin Fowler's books contain good information about separation of concerns in an enterprise environment. The two books which i recommend are

How to get the country name from IP address?

Hello All,
I am able get the IP address of the visitors by using
String ipAddress = request.getRemoteAddr(); .
I'm also getting the host name by using
InetAddress iaddress = InetAddress.getByName( ipAddress );
String ipaddr = iaddress.getHostName();
But... I'm not able to find the Country's name from which that IP is coming from.
Is there any class in JAVA that will help me find the respective country's name??
Thank u!!!

There is no magic way to tell country from IP address. You can guesstimate the country using a IP-to-country mapping database, with some accuracy.
I use the free version of the GeoIP (google for it) database; it is a file that you download, and they have a Java API or you can roll your own. They also have better quality databases for a fee, and apparently a web service. I prefer a file because it's faster and more reliable to check against a memory data structure than to make a long distance TCP/IP call. The web service isn't magic either; it is just an interface to the same database, and it doesn't give 100% accuracy, nothing will. If you use the file you may want to make it a monthly to-do item to download the latest version. There are other similar databases around too; google for "geolocation".

Change the Database Name in Essbase Studio

Hi All,
Happy new year to all of you.
Is there a way to change the database name in Essbase Studio, what I can see now once we have registered a database in Database Sources panel, we can't change the Database Name because it is always grayed out but the server name, user name and password can be changed.
Actually I have mentioned this issue to our team before starting development and they proposed me the schema that I can use, but suddenly our client did not agree with it that we have been using, and then our client asked us to use another schema, FYI we are using Oracle Database as the data source.
Can you guys here share how to manage this situation.
Thanks,
Rudy

For Essbase Studio, the configuration metadata are saved as CP_tablenames, look for the CP tables, and make proper database change for the database name.
1. Make a Oracle backup for the CP tables before you change the metadata so that you can get back in case if error
2. Change the CP_CONNECTION TABLE, NAME column
3. Change the CP_SOURCE table, column DNAME, for example, it is called TBC.Sales, change to NewDB.Sales
I am not sure if there are other table also need to be updated, anyway, when you update the DBname in the metadata level, everything should be consistent in all of the related tables. Here, I assume the new db has the same table names as the old db, if the new db has very different table names, recreating everything may be easier and has less risk.
