Help Using Oracle (In General)

I am new to Linux and Oracle, so please bear with me.
I finally was able to install Oracle 11g on my CentOS computer. (This took a long time...I'm a slow learner).
Now I'm trying to create an database or just trying to USE Oracle. Where and how do I create an new database?
I searched around this forum and saw that you should use the command "dbca" to create a database.
If this is true, I have several questions:
1. Where do I type this command (on root or on oracle user)?
2. Do I need to be in a specific directory?
3. How exactly do I use the command "dbca"?
I appreciate any help I can get. But please I need step by step solutions; providing me with a link to an Oracle documentation guide hasn't helped me.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/create.htm#g1034097 <--This guide is very confusing and not clear in it's directions.
Or maybe, does anyone know of an Oracle Tutorial for Dummies? This would help too. ;-)
Thanks again.
Note: Remember, I am new to Linux AND Oracle. Thank you!

Reading installation documentation and following it always makes things work better.
1. The docs are at http://tahiti.oracle.com
2. Use a supported operating system (free) such as Oracle Enterprise Linux (download at http://otn.oracle.com)
3. If you find you are confused by some aspects of the docs there are many of us that have posted examples on the web.
Mine are at http://morganslibrary.org/library.html under "Linux" with different demos for the most recent 3 versions.

Help using Oracle Diagnostic Logging (LoggingContext)

Hi,
We are developing a new Product from scratch and have decided to use as much as we can from Oracle Libraries. Currently we are using Oracle Diagnostic Logging (ODL) for logging in our application, having a wrapper on top of it, which will make our product as well in-line with other oracle product logging.
We have requirements to log based on LoggingContext as in Log4j's Mapped/Nested Diagnostic Context. I believe we can do the same using oracle.core.ojdl.logging.context.LoggingContext but can't find more information on how to use it.
Can anybody provide examples or links to learn, understand and implement using LoggingContext in ODL?

ODL generates log files in XML format only. Using ODL you can not have plain text format log files. You have to decide what is more desired - log rotation (that ODL provides) or text format (which is the default, non-ODL, format). If text format is more desired than don't enable ODL and write your own shell script to rotate application log (but that can only be done while OC4J is down).
At the same time if you are concern about readability of log file (i.e. text format is easier to read vs. xml format) than you might consider using one the log viewer tool (log viewer in EM or printlogs command line) provided by Oracle. Both of these tools help you view the logs in much more readable format than just looking at xml format log file.
(printlogs utility is under $OH/diagnostic/bin directory. Run "printlogs -help" to read about it).
Hope this helps.
Thanks

Help using oracle syntax "SUM(col1) over (order by col2)" using ODI

Hi all
I want to load data from oracle to ESSBASE using ODI, and I know oracle have such syntax sum(col1) over (order by col2,col3) which can get the accumulation data, e.g
Oracle data table
col1, col2, value
A 2009-1 10
A 2009-2 10
A 2009-3 10
And the essbase need
col1 col2 value
A 2009-1 10
A 2009-2 20
A 2009-3 30
However after i try this in ODI, error occur:
org.apache.bsf.BSFException: exception from Jython:

I know ODI think sum.. over must append group by , however it's not! How to solve this problem.
Thank All for your attention
SOS!
Ethan

Hi Ethan,
In my exeprnc I faced a similar kind of situation.
Two work arounds.
1. Write one procedure and execute the same using ODI procedure.
2. Customize a Km and use that KM in your interface.
I guess in your query Group by function is not needed. (if this is the case you can achive this by a smple customization step in KM)
for example : your current KM will generate a query like this:-
select x,y, sum(x) over (order by y) as sumx FROM TestTable group by x, y
and you need a query like this
select x,y, sum(x) over (order by y) as sumx FROM TestTable
go to your KM (duplicate the KM which you are using and rename _withoutGroup )
remove the group by function from select query
(remove the API function <%=snpRef.getGrpBy()%> from insert into i$ table step)
please let me know if you need more help on this
regards,
Rathish

Help needed in using oracle rules SDK

Hi,
For testing my rulesets using oracle rules SDK I doing the following:
1. Creation of dictionary, ruleSet.
2. Declared two kinds of globalVariable variables in my datamodel :
Final and non-Final.(Type of these varaibles are String and Double only)
3. Final globalVaraibles are used in creating rule's patterns.
4. Non-Final globalVariables are used in creating rule's action.
5. Functions are created for asserting globalVariables values and
returning non-final varaibles, since those are required as action
results.
6. In java code I am testing my ruleset (dict.testRuleSet()). Before
testing i am populating my final global variables (since these are used
in rule's patterns),
and updating datamodel.
The above procedure is working fine and I rules are successfully working.
Now, first of all i want to know if the above mentioned approach is correct or it needs to be reframed??
secondly, when i update datamodel with values (in java code itself) it
takes 4-5 seconds in updating it. This is the main issue that why it is
taking this much time??
any comment would be of great help.
Thanks in advance.

I will send up an alert for you, Colin. Even though I use iTunes for Mac, troubleshooting it isn't my forté.

Looking for some help with using Oracle stored procedures in vb2010

First off thank you to whoever lends me a hand with my problem. A little background first I am in a software development class and we are currently building our program using VB (I have no experience in this), and Oracle(currently in a Oracle class so I know how to use Oracle itself just not with VB).
I am using vb2010 express edition if that helps. Currently I have a stored procedure that takes a 4char "ID" that returns a position (ie, salesperson,manager ect). I want to use the position returned to determine what vb form is displayed (this is acting as a login as you dont want a salesperson accessing the accountants page for payroll ect).
Here is the code I have currently on the login page of my VB form
Imports Oracle.DataAccess.Client
Imports Oracle.DataAccess.Types
Public Class Login
Dim conn As New OracleConnection
Private Sub empID_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles empID.Click
End Sub
Private Sub LoginBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoginBtn.Click
conn.ConnectionString = "User ID = Auto" & _
";Password = ********" & _
";Data Source = XE"
conn.Open()
Dim sq1 As String = "Return_Position" 'name of procedure
Dim cmd As New OracleCommand(sq1, conn)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add(New OracleParameter("I_EmpID", OracleDbType.Char, 4)).Value = Emp_ID.Text
Dim dataReader As OracleDataReader = cmd.ExecuteReader
dataReader.Read()
Dim position As New ListBox
position.Items.Add(dataReader.GetString(0)) 'were I am getting an error, I also tried using the dataReader.getstring(0) to store its value in a string but its a no go
If position.FindStringExact("MANAGER") = "MANAGER" Then
Me.Hide()

I have read the oracle.net developer guide for using oracle in vb2010 and have successfully gotten through the document however they never use a stored procedure, since the teacher wants this program to user a layered architecture I cannot directly store sql queries like the document does, thus the reason I want to use stored procedures.
This is getting frustrating getting stuck with this having no background in VB, I could easily do this in c++ using file i/o even through it would be a pain in the rear....

Hello,
I am calling Oracle 11g stored procedures from VB.Net 2010. Here is a code sample (based on your code) you should be able to successfully implement in your application.
Please note that you may have to modify your stored procedure to include an OUT parameter (the employee position) if it doesn't have it yet.
Private Sub LoginBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoginBtn.Click
Dim sProcedureName As String = "Return_Position" 'name of stored procedure
Dim ORConn as OracleConnection, sConn as String
Dim sPosition as String, sDataSource as String, sSchema as String, sPWD as String
Dim cmd As OracleCommand
'please provide below sDataSource, sSchema and sPWD in order to connect to your Oracle DB
sConn = "Data Source=" & sDataSource & ";User Id=" & sSchema & ";Password=" & sPWD & ";"
ORConn = New OracleConnection(sConn)
ORConn.Open()
cmd = New OracleCommand(sProcedureName, ORConn)
With cmd
.CommandType = Data.CommandType.StoredProcedure
'input parameter in your stored procedure is EmpId
.Parameters.Add("EmpID", OracleDbType.Varchar2).Value = Emp_ID.Text
.Parameters.Item("EmpID").Direction = ParameterDirection.Input
'output parameter in your stored procedure is Emp_Position
.Parameters.Add("Emp_Position", OracleDbType.Varchar2).Direction = ParameterDirection.Output
.Parameters.Item("Emp_Position").Size = 50 'max number of characters for employee position
Try
.ExecuteNonQuery()
Catch ex As Exception
MsgBox(ex.Message)
Exit sub
End Try
End With
sPosition = cmd.Parameters.Item("Emp_Position").Value.ToString
'close Oracle command
If Not Cmd Is Nothing Then Cmd.Dispose()
Cmd = Nothing
'close Oracle connection
If Not ORConn Is Nothing Then
If not ORConn.State = 0 Then
ORConn.Close()
End If
ORConn.Dispose()
End If
ORConn = Nothing
If UCase(sPosition) = "MANAGER" Then
Me.Hide()
Dim CallMenu As New Menu()
CallMenu.ShowDialog()
End If
LoginBtn.Enabled = False

How to use oracle thin driver?...pls help

Hello. I am trying to insert a word file into my Oracle 9i database using JSP. I have tomcat running as my standalone server. So far, i have been using the sun.jdbc.odbc driver to implement all my DB accesses. Recently however, i found out that in order to use Oracle specific objects such as BLOBS or BFILES, i have to use the oracle thin driver or OCI driver.
So far, i have downloaded the thin driver and put it into the tomcat shared/common folder and also put the .jar file into my classpath. Now, i am having trouble as to how to call the oracle thin driver inside my JSP code.
My previous code read as:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:Andy","user","pass");
How do i switch over to the oracle thin driver in JSP? Any help would be much appreciated. Thank you
Andrew

Class.forName ("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@hostname:port:SSID", "user", "password");

Help! How To Use Oracle as SQL for a Forum with Related Post

Hi All,
I added an SMF forum on my [Tech Blog|http://oscarmini.com] using the sub directory forum. Now I want to encode a fresh forum using Oracle for the database instead of the usual MySQL. I don't really know if this is possible. If it is, then let me know if their is a script for this, and so I can ask other related questions too.
But firstly, is it possible?

I think Oracle have taken down all the sample applications.
As I recall it was quite controversial at the time. Supposedly they're upgrading them to the latest version of Apex - some of them were quite old - but obviously there's a gaping void in the meantime.
The official Oracle statement is [url http://www.oracle.com/technetwork/developer-tools/apex/application-express/packaged-apps-090453.html]here. It turns out they're not going to upgrade the apps but rewrite them entirely. So I predict the gaping void will last for some time yet :(
There's [url https://forums.oracle.com/forums/thread.jspa?threadID=2253686&start=0&tstart=0]a thread on the Apex forum which has a link to the Oracle Chinese website, which still has the samople apps, including the Discussion Forum. Download it (if you dare) from [url http://translate.google.com/translate?js=n&prev=_t&hl=en&ie=UTF-8&layout=2&eotf=1&sl=auto&tl=en&u=http%3A%2F%2Fwww.oracle.com%2Ftechnetwork%2Fcn%2Fdeveloper-tools%2Fapex%2Fpackaged-apps-087541-zhs.html]here.

But when I did your suggestion:

I got the same error as before which is:

Using Oracle Text with CLOB field containing multiple languages

I'm using Oracle 10g (NLS_CHARACTERSET is set to. AL32UTF8) and have a table with a CLOB field which is storing text written in either English and/or Simplified Chinese.
The following index has been created on this field:
CREATE INDEX text_index
ON text_table(text_field)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('FILTER CTXSYS.INSO_FILTER');
I'm having issues in returning text which matches the Chinese text using the CONTAINS operator. For some reason the following query is returning rows which do not contain any Chinese text:
SELECT *
FROM text_table
WHERE contains(text_field,'炫%') > 1;
A newsgroup user advised me to produce an explain plan using ctx_query.explain.
I created 2 explain plans, one which was searching the index for 'A%' and the other searching for the Simplified Chinese character '炫%'. The results for the first test were as expected whereby the values contained within the OBJECT_NAME field all began with the letter 'A'.
The second test however produced somewhat unexpected results. The OBJECT_NAME field this time contained various words, both English and Simplified Chinese. I could be wrong but it appeared to store every individual word in the CLOB field. Both tests produced different EQUIVALENCE rows, the first test was:
OPTIONS = Null
OBJECT_NAME = A%
Whereas the second test produced:
OPTIONS = (?)
OBJECT_NAME = %
Am I right in thinking the Simplified Chinese character is for some reason being converted to a '?' character?
Any help on this will be much appreciated.

As you're not specifying a lexer to use, it will use the BASIC_LEXER, designed for space-separated European-type languages. This won't work effectively with Chinese.
If you know which documents are Chinese and which are English, you can write this into a LANGUAGE column and use the MULTI_LEXER - this will allow you to specify BASIC_LEXER for the English texts, and CHINESE_LEXER or CHINESE_VGRAM_LEXER for the Chinese texts.
If you don't know the language, you must use either WORLD_LEXER (10g) or AUTO_LEXER (11g). These lexers will automatically determine the language of the documents and index them appropriately. In general. MULTI_LEXER will be faster and more accurate than either of the automatic alternatives.
When querying for Chinese characters you need to be very careful with your NLS_LANG settings. You need to make sure that the character set defined in NLS_LANG is the same as the character set from which you've pasted (or typed) the chinese characters.
The "?" in output usually just means "I don't know how to translate this character into your output character set". Sometimes it may appear as a reversed question mark.
