Number of views in an Oracle database

a. Is there any reason number of views in a database will have a "big" impact in the performace of the database. I believe "No". But I needs some facts to prove that.
b. If there will be an impact, can any one tell me what is that number will be for a machine which 48GB memory with 24 processors running Oracle 9I on a HP environment.

Well.. very "abstract" questions, but I think
a. it depends
number of views per se doesn't matter. Actually I have experienced cases where a few "bad" views brought the machine to its knees. Or using views when no proper statistics was available.
b. How big is a house?
:) what is x if we know that y is 48 and z 24?
But you have a very powerful machine there, and to some extent you could hide a lot of performance problems with it.

How to view history in oracle database?

hi..
is there any method to view history of sqlplus command in oracle database ?.
This is because i would like to know what my vendor done to the oracle..
Thank you,
baharin

This is because i would like to know what my vendor done to the oracle..Interesting enough.
There is no direct method to view the commands executed from SQL*Plus.
If that sqlplus session was launched on Windows platform AND the command window buffer was already set to a higher value AND you have not yet closed that command window then you can launch sqlplus again in the same window and go through the history of commands.
Else, you can try mining your archive logs (assuming your database is in archive log mode), find out the commands executed from that particular session and hope you get all of them (as some commands are/were not supported by log miner).

Can I define tables/views of another oracle database as data sources in DBI?

Hi!
Assuming I created a dblink between an Oracle EBS database and another oracle database and I wish to create custom dashboards and reports in Oracle Daily Business Intelligence, will the tables/views from the another oracle database be allowed as the data sources?
Thanks.

Pl do not post duplicates - Can I read data from other database and tables in Oracle Daily Business Intelligence?
Whether the custom tables are in the same database or a separate database is a trivial issue - a database link and local synonyms can easily mask where the tables are located.

How to find the number of ODBC connections to Oracle Database

Hi All,
How to find the number of ODBC connections and all connections to the Database in last week. Are there any views to get this information?
Thanks in advance,
Mahi

What Ed said is true that Oracle doesn't note which type of protocol is connecting to the database, however, you can see which program is accessing the database.
For example: if you already know of a user using ODBC, you can verify as:
select username, osuser, terminal, program from v$session where username = 'SCOTT'
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Assuming that you can confirm the progam noted in the above (example) is the one using ODBC, then you can change the query such as:
SQL> select username, osuser, terminal, program from v$session where program = 'w3wp.exe';
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Just for kicks, I checked our listener.log file, but there was no reference of odbc in it either.
Hope this helps...

Crystal Report Viewer Not Releasing Oracle Database Connections

I have a very simple vb.net 3.5 web application that uses the Crystal Report viewer 2008 to open a report. My requirements are as follows:
1. Reports are built by another company and provided to us and used in a web environment
2. All reports contain parameter fields
3. The web application must be generic enough that a report can be added to a list and the user simply selects the report and provides database login information. The Crystal report viewer with handle the request for parameter values and prompt the user for their values.
4. All reports connect to an Oracle 10g server.
The above requirements have been meet and we have an extremely simple web application that runs the reports. It is working very well other than the crystal report viewer is not releasing the database connections. This is bad because the credentials are on a per user basis and that same user must login to a different oracle application simultaneously. They are being denied access because the credentials are already in use. We do not have control nor influence over the policies in use on the Oracle server. Ideally we would like to control the Crystal Report viewer so that it closes connections after use.
The web application code is:
Private Sub viewReports_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
If Not IsPostBack Then
ConfigureCrystalReport()
End If
End Sub
Private Sub ConfigureCrystalReport()
'Load the Crystal Report viewer with a report.
Try
Dim reportPath As String = Server.MapPath(Session("reportname"))
crViewer.ReportSource = reportPath
Catch ex As Exception
Response.Write(Server.MapPath(Session("reportname")) & "
" & ex.Message.ToString & "
" & ex.StackTrace.ToString)
End Try
End Sub
Can anyone shed some light on this topic? Thank you

Hello, Timothy;
By default, having the report in session will hold it open for 20 minutes.
If you create the report as a ReportDocument object you can take it out of session and release it more efficiently. That will release the connection.
    Private Sub ConfigureCrystalReports()
        If (Session("hierarchicalGroupingReport") Is Nothing) Then
            hierarchicalGroupingReport = New ReportDocument()
            hierarchicalGroupingReport.Load(Server.MapPath("Hierarchical Grouping.rpt"))
            Session("hierarchicalGroupingReport") = hierarchicalGroupingReport
        Else
            hierarchicalGroupingReport = CType(Session("hierarchicalGroupingReport"), ReportDocument)
        End If
        myCrystalReportViewer.ReportSource = hierarchicalGroupingReport
    End Sub
In the Form Unload of the Viewer:
            'Take the report out of session
            Session("hierarchicalGroupingReport") = Nothing
            Session.Contents.Remove("hierarchicalGroupingReport")
            'Clean up the ReportDocument object
            hierarchicalGroupingReport.Close
            hierarchicalGroupingReport.Dispose()
            hierarchicalGroupingReport = Nothing
            GC.Collect()

Hi,
the view V$PARAMETER must be accessed through SAP/Oracle Database Monitor lets you view the active Oracle database parameters and the contents of the init.ora file.
Alternatively, you can use transaction st04. You need to apply SAP Note 706927 before using the database monitor.
Hope this information is help to you.

We were able to do the same thing with Oracle Application Server and Oracle WebLogic Server. I cannot remember how different the processes were, but it seems like they were very similar. I am going to give you the instructions on how we implemented a "Read PDF" procedure on the WebLogic Server. If you are still on the Application Server you may have to do some Google searches, but it all boils down to the mod_plsql DAD Configuration file.
Our PDF was located in a table with the following structure:
CASE_DOCUMENTS
   (id_document                    NUMBER NOT NULL,
    doc_blob                       BLOB,
    note                           VARCHAR2(240),
    created_by                     VARCHAR2(20) NOT NULL,
    created_dt                     DATE NOT NULL,
    case_id                        NUMBER NOT NULL,
    filename                       VARCHAR2(100) NOT NULL)Based on that table structure we created a procedure named READ_PDF which you will reference below in the dads.conf file below:
CREATE or REPLACE procedure read_pdf (p_id_document IN number)
is
view_file     blob;
BEGIN
select doc_blob
    into view_file
    from case_documents
   where id_document = p_id_document;
OWA_UTIL.MIME_HEADER ('APPLICATION/PDF', FALSE);
HTP.P ('CONTENT-LENGTH: ' || DBMS_LOB.GETLENGTH (view_file));
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (view_file);
END;
GRANT EXECUTE ON read_pdf TO financial_user_role -- Name of role to execute
/Basically, you are passing in one parameter and that is the primary key for your table. You are selecting the pdf stored in a BLOB for that primary key. The commands below that allow the pdf to open up so you can view it – we got this off some search we did a few years ago.
Now, you need to add logic to your Oracle Form that will call the procedure above, but the URL is based on the dads.conf file that we will set up below… Anyway, we created a button on the form module with a label of "View". In the WHEN-BUTTON-PRESSED trigger the logic looks like this:
-- The View logic uses the DAD (Database Access Descriptors) method to view a .pdf file from the form.
-- The DAD was created on WebLogic Server with the name findadgen. This allows an http request be made
-- to the database.
declare
v_file          varchar2(400);
v_success       boolean;
ret_val         number;
v_http_link     varchar2(400);
begin
-- The format of the link is as follows: hostname:port/pls/DAD_name/procedure_name
v_http_link := 'http://finas03:8888/pls/findadgen/read_pdf?p_id_document=' || :case_documents.id_document;
web.show_document(v_http_link, '_BLANK');
end;The name of our WebLogic Server is "finas03" so that is what is listed in the URL. The "findadgen" is the name of the <Location> in the dads.conf file below, the "read_pdf" is the name of the procedure we created above, the "p_id_document=" is the IN parameter listed in the READ_PDF procedure created above, and the ":case_documents.id_document" is the reference to the primary key in our Oracle Form.
For WebLogic, you can either go through Enterprise Manager (directions below) or update the dads.conf file on the filesystem directly (if you update the dads.conf file directly then skip to step 4 and ignore step 5):
1.     Enterprise Manager -> Web Tier -> ohs1
2.     Oracle HTTP Server (pull-down) – Administration – Advance Configuration
3.     Select File – dads.conf
4.     Add something similar:
# ============================================================================
#                     mod_plsql DAD Configuration File
# ============================================================================
# 1. Please refer to dads.README for a description of this file
# ============================================================================
# Note: This file should typically be included in your plsql.conf file with
# the "include" directive.
# Hint: You can look at some sample DADs in the dads.README file
# ============================================================================
<Location /pls/findadgen>
    SetHandler pls_handler
    Order allow,deny
    Allow from All
    AllowOverride None
    PlsqlDatabaseUsername financial
    PlsqlDatabasePassword sdo_3#d1
    PlsqlDatabaseConnectString ffindbTNSFormat
    PlsqlNLSLanguage AMERICAN_AMERICA.WE8ISO8859P1
    PlsqlAuthenticationMode Basic
    PlsqlDefaultPage read_pdf
</Location>You are adding the <Location> section to your dads.conf file. The "finddadgen" is the name that you will reference in a change you fill make to your Oracle Form. The "financial" is the Schema, the "sdo_3#d1" is the password for that Schema, the "ffindb" is the database that the stored procedure is located on, and the "read_pdf" is a stored procedure you will have to create in order to read the pdf.
5.     Press the "Apply" Button
6.     Obfuscate the DAD password by running the dadTool.pl script located in $ORACLE_HOME/bin (This was done on Unix on our server with the following commands):
$> LD_LIBRARY_PATH=$ORACLE_HOME/lib;export LD_LIBRARY_PATH
$> cd $ORACLE_HOME/bin
$> perl dadTool.pl -f /u01/app/oracle/middleware/asinst_1/config/OHS/ohs1/mod_plsql/dads.conf
7.     Restart the Oracle HTTP Server using Fusion Middleware Control:
Enterprise Manager -> Web Tier -> ohs1
Oracle HTTP Server – Control – Shutdown
Oracle HTTP Server – Control – Start Up
If you followed the instructions above, you should have created a stored procedure, added logic to your Oracle form to reference that stored procedure, and created an entry in the dads.conf file. Once you move the form onto the server and you restart the HTTP Service, you should be able to view a pdf that is stored in a table directly from your Oracle Form.

MS Access: Oracle9i: How To: Open an Oracle "VIEW" in a DAO Database ???

NEWBIE Alert!
Esteemed Forum Participants and Lurkers:
===============================
I have successfully opened an Access (2002) DAO Database from a remote Oracle database and fetched all of the TableDefs (all 534 of them!), but I'm told that what I actually need is 2 'Views'. I have tried to access these 'Views' as TableDefs and as QueryDefs, but these attempts cause an error message that they "don't exist in the collections". Here is my Access VBA code ...
Sub DAO_TEST()
    Dim myDAOWorkspc As DAO.Workspace 'Declare a Workspace
    Dim myDAOdb As DAO.Database        'Declare a handle for the Oracle Database
    Dim aTable As DAO.TableDef         'Declare an iterator for the TableDefs
    Dim aQuery As DAO.QueryDef
    Dim strODBC As String 'Declare a Connection String
    ' Initialize the connection string
    strODBC = "ODBC;UID=myID;PWD=myPWD;DSN=ORA_DB"
    ' Create a Workspace ... I have no idea what to declare as User and Pwd,
    ' but I am an admin (but that's NOT my user ID) and this works!
    Set myDAOWorkspc = DAO.CreateWorkspace("myWorkspc", "admin", "")
    ' THANKS to Justin Cave for the following !!!
    ' For DAO to Oracle: Control Panel > Administrative Tools > Data Sources (ODBC)
    ' Select appropriate DSN and click Configure button
    ' Select Workarounds tab and turn "Set Metadata Id Default to SQL_TRUE" checkbox to CHECKED
    '                               1st param is DNS NAME!!!
    Set myDAOdb = myDAOWorkspc.OpenDatabase("ORA_DB", dbDriverComplete, True, strODBC)
'> ERROR: Item not found in this collection!!!
    Set aTable = myDAOdb.TableDefs("ad_owner.itm_dtl_view")
'> ERROR: Item not found in this collection!!!
    Set aQuery = myDAOdb.QueryDefs("ad_owner.itm_dtl_view")
' This WORKS with the above errors commented out
    Debug.Print "    START OF TABLE NAMES"
    For Each aTable In myDAOdb.TableDefs
        Debug.Print aTable.Name
    Next
    ' Clean up the house please
    myDAOdb.Close
    Set aTable = Nothing
    Set aQuery = Nothing
    Set myDAOdb = Nothing
    Set myDAOWorkspc = Nothing
End SubI need to figure out how to access "Views" such as "ad_owner.itm_dtl_view". Thank you for any and all comments, suggestions, and assistance.
Blessings in abundance, all the best, and ENJOY!

Number of available records in Oracle 10g express database

Hi,
I am facing problems in getting the number of available records in Oracle 10g express database with the following query.
string filename = dbObject.FILENAME;
string vendorID = dbObject.VENDOR_ID;
OracleCommand myCommand = _connection.CreateCommand();
myCommand.CommandText = "SELECT COUNT(*) FROM ASSET_PROCESSING_OUTPUT WHERE *FILENAME = :filename AND VENDOR_ID = :vendorID*";
myCommand.CommandType = CommandType.Text;
myCommand.Parameters.AddWithValue("filename", filename);
myCommand.Parameters.AddWithValue("vendorID", vendorID);
OracleDataReader reader = myCommand.ExecuteReader();
Using this command how can I get if the record exists in the database with the given value.
Thanks in advance.

It appears you're only executing the statement. You need to fetch the result to see the value returned by the SELECT statement.

INVALID Oracle Database Catalog Views 10.1.0.5.0

I am trying to resolve an INVALID state on the Oracle Database Catalog Views component of an Oracle 10.1.0.5.0 database.
I was trying to resolve an issue with Data Pump by running: catalog.sql, catproc.sql and catexp.sql as SYS to add the EXFSYS schema.
Doing this made the Oracle Database Catalog Views go INVALID.
I have 61 invalid objects after running utlrp.sql, 26 of these are owned by SYS.
Anyone know of a good way to resolve this issue or a metalink note, other link they can guide me to? I would like to avoid having to rebuild the database.
Thanks!!!

Anyway .... this is how to resolve this issue:
Note: Ensure that the SHARED_POOL_SIZE and JAVA_POOL_SIZE parameters are set to at least 150M each, and then restart the instance in MIGRATE mode and execute catpatch as detailed in the following steps:
Before starting this process, notify users of database that the database will be unavailable for approximately 2 hours. Proceed with proper notification procedures before shutting down the database.
1.     sqlplus /nolog
2.     spool $ORACLE_HOME/rdbms/log/catpatch_ddmmyy.log
3.     connect / as sysdba
4.     alter system set shared_pool_size = 200M scope=spfile; (if necessary)
5.     alter system set java_pool_size = 150M scope=spfile; (if necessary)
6.     shutdown immediate
7.     startup migrate
8.     @$ORACLE_HOME/rdbms/admin/catpatch.sql
9.     spool off
10.     shutdown immediate
11.     startup
12.     (validate): select comp_name,version,status from dba_registry;

Replication of database views/materialized views from big oracle to mobile client

Hi all,
Has anyone done a replication of a view or a materialized view
from big oracle to oracle lite? I can get replication of a
database table happening(although I cant seem to find the table
when I log into the odb using msql) but it just doesn't seem to
work with views(hence the path I have taken which is to use
materialized views). Anyone? Cheers

Hello,
Yesterday I met the same problem and very sad about this, however, my story is much more complicated (I think so).
I have 6 databases:
2 - 11g
2 - 10g
2 - 9i
Every database of each release has different characterset(UTF8 and AL16UTF16).
I am trying to create Materialized view with FAST REFRESH on Oracle 11g, when master tables are located on 10g database and 9i database.
Materialized view, which points to 9i database, was successfully created.
Materialized view, which points to 10g database, gets ORA-12028
Like you, I tried many notes from METALINK and thought at the begining that the problem is my characterset. But, when the materialized views were successfully built on Oracle 9i database, I understood that the problem is something else.
Did you find the actual reason why this issue does not work??
Thanks,
Alex
