Not able to connect to Oracle 10G server

Hi All
I have installed Oracle Clinet 10G and i am able to connect to oracle server using sql plus, but not through Microsoft OLEDB data provider for Oracle.
Error : Test Connection Failed because of an error initializing provider, oracle error occured,
but error message could not be reterived from Oracle.
also before installing Oracle clinet i have SQL Server 2005 and 2008 client in my system.

consider using WireShark or Ethereal to packect sniff the data exchange between MS client & Oracle listener/DB

    please let me konw how to connect to the sql developer.
    Did you perhaps do a custom install? The DB software includes a version of sql developer and, by default, installs it in the sqldeveloper folder of the DB_HOME. Does that folder have sql developer in it?
    I suggest that you NOT use the version of sql developer that ships with the database. That version will NOT be the current version.
    Download the current version of SQL Developer, unzip it into a new folder and create a desktop icon for it.
    http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html
    The current version includes many, many bug fixes from that earlier DB version and you will have far fewer probems with it.

  • Not able to connect with Oracle server through VBScript without DSN

    Hi
    I have both Oracle9i and Oracle10g clients installed with local system.
    I am able to connect to Oracle Database 11g Enterprise edition server though sqlplus through command prompt and also through AQT without any error.
    As the server has lots of database ,whenever I connect to a particular database through sqlplus from command prompt,I connect as below
    C:>sqlplus username/password@service_name
    and it gets connected without any error.
    When I am trying to connect the same database through VB Script,I am getting ORA-12560 TNS:Protocol Adaptor Error.
    Below is the connection string I am using:
    Database_String = "SERVER=xxxx.vvvn.Com;Driver={Oracle in OraHome92};DATABASE=service_name;user id=userid; password=passowrd"
    I have installed a Oracle10g server in my local system and tried to connect the same way and I was successfully ,but its not working when the server is running remotely.
    Does it make any difference with the version of driver being used ?Should I need to modify my connection string anyway.
    Please help me as to identify the issue.Thank you very much in advance.

  • Not able to connect to Oracle EBS from host Windows 7

    Hi, I have installed oracle EBS version 12.1.1 (32 bit) on OEL ver 6.3 (32 bit). I have installed Linux on Oracle VM virtualbox ver 4.1.16.
    I am having host OS as Windows 7 home on my laptop.
    While setting up the Network in Oracle VM virtualbox, I have set "attached to" as 'Host Only Adapter'.

    I have entered following setting in C:\Windows\System32\drivers\etc\hosts file.

  • Connection to Oracle 10g server on Oracle 8i client machine

    Hi guys,
    I wonder if you could help. I need to access Oracle 10G server using a client machine with Oracle 8i on it. I am getting the following error: "ORA-12154: TNS:could not resolve service name"
    I believe I have tnsnames.ora correctly set for the service. I was wondering if I am missing something or it is just not possible to connect to 10g. Do I need to install the Oracle 10g client on the same client machine as 8i? Would they run Ok together?
    Urgent response would be appreciated
    Thanks

    There are limitations in your combination (8.1.7 Client - 10g server), but you should get a different error. Anyway, please post the following :
    - the exact (complete, e.g. 8.1.7.4, 10.1.0.3) server and client version
    - from the client the content of sqlnet.ora and the relevant part of tnsnames.ora
    - from the server the result of "lsnrctl services"
    Would they run Ok together?Yes, of course you have to use different Oracle homes.

  • Not Able to Connect to Intranet Web Server

    We have ASA5550 (ver. 8.0.4). We setup Split-tunneling. The Remote users were NOT able to access the intranet web server using Cisco VPN client. However, they were able to access other internal resources. We were able to ping the IP address of the Intranet Web server, but we were NOT able to ping by name. Do you have any suggestions?
    Thanks.

    Thanks for your response and information. The VPN adapter shows the Corporate office's DNS server. When I typed NSLOOKUP, the Remote computer also showed the Corporate office's DNS server. So, does it mean the DNS is setup correctly on the ASA?
    We have about 100 Remote offices, do we need to put in 100 DNS servers for Split-DNS? The Remote offices are using Cisco VPN client to connect to us.
    Thanks.

  • Clients not able to connect to MS exchange server over a cisco switch

    Hello,
    I have a Cisco L3 switch.
    I have a Exchange server and until i split the network into every thing was working ok, meaning the clients can connect to the Exchange without issues.
    But after i split the network into 2 vlans, moving the exchange in one vlan and the clients in another vlan, i have complains saying that the users are not able to connect to exchange periodically.
    Even users from the same subnet also cannot connect to the exchange often.
    Meaning the clients can connect to the exchange and suddenly it will stop working. at the same time i can ping the exchange and that shows there is no routing issue or LAN issue.
    But still clients cant connect to the exchange, when i reboot it will start working again for some time.
    wondering whether it could be related to any network related issue or MTU or PMTUD issues.
    The whole issue started only after we split the network into two vlans.

    If you have physical access to the switch, it may save time to look at the port LEDs which give you the link status or may indicate an error condition (if red or orange). The table below describes the LED status indicators for Ethernet modules or fixed-configuration switches:

  • Not able to connect to oracle 11g database source through OBI Server

    Hi,
    I am having an issue regarding the database connectivity.
    Iam unable to connect to the oracle 11g database through OBI server. However its connecting through SQL Plus with same username/password@hoststring. Its giving the error as :
    [nQSError: 17001]Oracle Error code:1017,message:ORA-01017: invalid username/password; logon denied at OCI call OCILogon
    [nQSError: 17014]Could not connect to Oracle database.
    Please help me out in resolving the issue.

    If it's working in one place and not the other then it's obviously not an OBIEE problem.
    Are you typing it in right??
    Do you have multiple tnsnames.ora files pointing to different databases, maybe sqlplus is picking up one and toad & OBIEE the other and so the username/pw is wrong for that database?
    There's a limited amount that can be said to help, as the error is 100% clear what the problem is :) it's just working out whether you're connecting to the database that you think you are connecting to, and then whether the username & PW you're entering is correct for that DB.
    BTW OBIEE 10.1.3.4 is supported with 11g, and we're using it without problem here.

  • Not able to connect to oracle 11g using toad9.6

    Hey...
    I installed 11g on Win7- 64 bit. I'm able to connect to DB using Sql*plus and cmd prompt but when i try to connect through toad, it says no client installed.
    I installed 11g with "Desktop class" option.
    any suggestions ???

    Hi,
    1. If you have installed db and toad on the same machine, then the ORACLE_HOME of the database can be used as client.
    2. But if you have installed Database on machine1 and you try to connect from laptop1 then on laptop1 client must be installed (to allow TNS communication).
    In case 1 above, check installed clients in the window (Session -> New Connection) on TOAD and make sure it is not red. And define TNSNAMES.ORA in the same oracle home listed in installed clients.
    In case 2 above, you must have to install a client to allow the communucation between toad and server.
    Thanks
