Oracle 9i database connection

hi
when I coonect to database in Java, I got error message:
connection failedIo exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=153092352)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
Cheers, Helen

ERR=12505 resolves to an Oracle error:
TNS-12505 TNS:listener could not resolve SID given in connect descriptor
Cause: The SID in CONNECT_DATA was not found in the listener's tables.
Action: Check to make sure that the SID specified is correct. The SIDs that are currently registered with the listener can be obtained by typing "LSNRCTL SERVICES listener_name". These SIDs correspond to SID_NAMEs in TNSNAMES.ORA, or DB_NAMES in the INIT.ORA file.

While creating MViews in oracle 9i database connecting to table in an orac

Hi all,.
While creating MViews in oracle 9i database connecting to table in an oracle 11g database....
Eg : create materilized view testmview as select * from testtable@db_linkname
ORA-03113: end-of-file on communication channel
any idea
Regards,
Shiju

There would be a trace file written on the 11g database server. Please review the trace file.
Your 9.2 environment must be running 9.2.0.4 or higher. The 9.2.0.4 is the minimum patchset level required for it to be supported connecting to an 11g (11.1 or 11.2) database.

Programm change in Oracle ADF database connection

Hello!
Our company uses an application implemented in Oracle Forms. We have about 2500 users. Each user works with a database using Oracle c your login / password.
We want to migrate to Oracle ADF. But the concept of Oracle ADF - under a single user connection.
But the position of the database administrators - do not use OracleInternetDirectory (LDAP), does not create users in WebLogic. :(
In our company, users are created in the database Oracle. Users are database role.
Our idea is to send in an application ADF user name and password. Safety is solved at the database level.
Can I do this:
1. When the application starts to change the ADF database connection to a user username / password?
2. Can there be problems in the future?
3. Are there any examples?
Please help

Hi,
You can create a custom authentication provider in WLS that uses a JAAS Login Module that attempts to connect to the database for authentication pupose. The application itself would run with a JDBC Data Source, so that you only use the database account to authenticate the user and get his/her database roles as authorization groups. I have a sample for this on my to-do list but so far hadn't the time to get to it. So yes, you don't need OID or LDAp to manage users but could keep going using the database

Error in Oracle Lite Database connection

Hi,
I have installed the Oracle Application server 10.1.3.1.0 on my laptop (basic installation).
I tried to define a database connection in the JDeveloper connection navigator to the Oracle lite database. When I test the connection I got an error:
"Internal Error:Invalid Connect String".
I have defined in the connection tab of the Edit database connection in the following way:
Driver class: oracle.lite.poljdbc.POLJDBCDriver
Library: OLite
Classpath: C:\product\10.1.3.1\OracleAS_1\bpel\lib\olite40.jar
URL: jdbc:polite4@localhost:100:orabpel
Could anyone tell me which user and password I should define for the oracle lite database which is delivered with Oracle Application server 10.1.3.1.0?

Hi,
Did you start the SOA suite on your workstation?
If so, can you reach the BPEL Console
if so, check via Enterprise Manager the connect string in the OC4J instance of BPEL (oc4j_soa -> administartion -> JDBC > conenctions, or data-sources.xml)
Copy the connect string into your OLite config if it works

For database access from Java, you will use JDBC.
For the specifics of the oracle spatial database, you'll have to check the documentation/forum of Oracle.

Oracle 11G + Database Connection taking too much Time

Hi ,
I am using Oracle 11G . When i try to connect to oracle database
sqlplus system/impetus@database
it takes too much time ( more than 1 min )
I am not getting why this is happening ?
Before some day it was working fine but suddenly the problem occurred.. Is this issue is related to log files generated by oracle or memory related issue ( sga and pga)..
Any Help please ?

Darn! /tmp/capture.log does not contain what I expected it to contain.
So a different approach is needed.
issue the following command:
script /tmp/capture.log
#now you are in a new shell & issue the next 3 lines
strace sqlplus system/impetus@database
exit
Ctrl-d (Control D)
now issue the following commands.
ls -l /tmp/capture.log
wc -l /tmp/capture.log
Post the results from 2 commands above back here

Oracle 11g database Connection & Response are very slow

I have an ORACLE 11g R2 on lRed Hat Enterprise Linux Server release 5.3 (Tikanga).
initially it was working fine.
Now a days while attempting to connect into the database from network using @service_name
it takes a lot of time to establish the connection and even it gets connected the query response time is very high.
on the other hand if I connect from the native database machine's terminal without @service_name it works fine & the response time is convincing. But even from the native database machine's terminal with @service_name it is giving me the same pain.
can any body help me how to fix this.
Thanks in advance..

Oracle 8i Database Connection Error

Hello
I have installed Oracle8i Enterprise on WinNT
4.0.However I am unable to connect to the
database thru' SQLPlus and I am getting the above error "TNS COULD NOT RESOLVE SERVICE NAME".I also checked the same thru' Net8i
assistant and tried testing of connection to database which has been created under my name
"Sumit" .I am therefore unable to connect to the database and getting similar errors ORA-12541 and sometimes ORA-01034.Please help me out.The login user name I am using is "scott"
password "tiger" and hoststring is "Sumit".
Thanks

Dear Sudip,
Thanks a lot for responding to my message ..I had lost hope of
receiving a response.Sudip,I tried connecting throu' Net8 configuration
as "SYSTEM" and password "MANAGER" but couldnt connect thro'.Although
I must mention that I could log on to SQLPLUS as INTERNAL/ORACLE after
which I gave the STARTUP command .The Oracle instance got started
however it also gave me an error ORA-00205 "error in identifying
controlfile, check alert log for more info".Now I tried to create a
SCOTT/TIGER schema but the script does not run and I get the following
error
SP2-0310: unable to open file "OraHome81\RDBMS\ADMIN\SCOTT.SQL"
and the same with "Sumit\RDBMS\ADMIN\SCOTT.SQL" .I am neither able to
create a table as it gives "database not open error" .
Sudip there is another aspect which I would like to bring to your
attention .It is that in the Control panel,when I click the server icon
it gives me "not enough server memory to process this command".
Also when I click the Services icon and try to start the
OraHome81Management server it gives me "the system could not find the
environment option that was entered" and is unable to start and with
the OraHome81TNSListener it gives me "the process terminated
unexpectedly " error and is unable to start either.
Now I wonder where the problem could lie !.Could it be with the OS
--WinNt and if so what could be the way to rectify it.Please help if
you can or alternatively if you know about any other forum where this
problem can be addressed..Thanks again..REGARDS

What is that i need to do for connectioning to Oracle 7 server at remotely.

Error
java.sql.SQLException: Io exception: The Network
Adapter could not establish the connection
Is this a driver problem ?It does not appear like a driver problem.
It could be:
a. A network problem
b. A configuration problem (something to do with TNSNAMES.ORA)
c. An incorrect hostname or port being used in your code (which you have not posted)
d. Something that I am not aware of.
Are you able to connect to the instance using SQL-Plus?

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()

Sql * plus 9 is not able to connect oracle 7 database

Today I have installed oracle 9i release 2 and found that the sql * plus provided with is unable to connect oracle database version 7. But before that we were able to connect the oracle 7 database well.
Any one having a clue on that...?
Is it a product bug...?
If so then please provide me some alternative solution clue or patch download link. Please remember in any condition currently it is not possible discard my oracle 7 database.
With Regards.
Soumen.

No, it is not a bug. You just cannot connect with Ora9i R2 SQL*Plus to an Ora7 database.You cannot create a DB link between the two database either, if you are planning on doing that.
A solution is to install Ora8 client, which can connect to both Ora9 and Ora7 database (but a db link will stil be impossible).
