Is OEM 10g functional withou SYS user connection?

Hi,
By our policies we don't have remote sys connectrion. However, many OEM operations have some configuration that requires SYS login. How do I go about it?
Thanks!
Alex

<<By our policies we don't have remote sys connection.>>
Do you mean that you should not use the user 'sys' to connect to the database from a remote location?
If that is the case, you may be able to make use of the SYSDBA and SYSOPER system privileges. What is your initialization parameter 'remote_login_passwordfile' set to?
The following link may be of help.

  • SYS user connects at database level, is it correct?

    My senior colleague has given me following information about the sys user. I want to know, is it correct?
    Since SYS user connects at the database level, therefore, on killing the active session of the SYS user,only the current statement is cancelled. The database session does not disconnect. Instead it continues to run the remaining statements in the script file in case we are running a script file containing a lot of SQL statements.

Instead it continues to run the remaining statements in the script file in case we are running a script file containing a lot of SQL statements.Running a SQL script very likely means SQL*Plus is used. One of two types of Oracle sessions will be created via sqlplus. A dedicated session. Or a shared server session.
    A dedicated session can also be local (sqlplus connects "directly" to the dedicated server process), or remote (sqlplus connects via tcp/ip to the dedicated server process).
    A server session is usually "killed" using the alter system kill session command. Despite the differences between shared and dedicated server connections, the end result is the same. The session terminates abnormally (session UGA will be released, session will be cleaned up, rolled back, etc) - and the session ceases to exist.
    So irrespective of how that sqlplus session runs that script - the session, when killed, will cause a sqlplus failure. And no subsequent script commands would be executed by that Oracle session.
    What can happen is that sqlplus continues running, continues reading the script, and continues submitting commands to be executed. However, with the server session killed, there is no server process to service the commands submitted by the sqlplus client. In this case, sqlplus will throw the error "+SP2-0640: Not connected+" after each of the commands it tries to execute after the server session was killed.
    The only time when sqlplus will be able to continue is when the session is not killed, but interrupted. The Oracle Call Interface (OCI) supports a OCIBreak() call - allowing the client to interrupt-and-abort the request that its server session is currently executing.
    For example, sqlplus sends a OCIBreak() while it waits for a server response (e.g. waiting for the answer to a SQL select query), when the user presses Ctrl-Break to abort that request.
    In this case, the session still exists - and the client can issue a new request that the session will service. But an OCIBreak() cannot be triggered (to my knowledge) externally from another Oracle session. You need to send the client process a "break request" (like a Ctrl-Break keystroke) in order to trigger that client process to make an OCIBreak() call to Oracle and interrupt its server process.

  • How to change password of sys user connected as sysdba?

    How to change password of sys user connected as sysdba?
    I have connected with user name sys as sysdba in oracle 9i with password oracle.
    I want to change the password . I typed password and pressed entered. It asks me to type old password, then new password and retype the new password. When I press enter it gives error message "ERROR:
    ORA-28008: invalid old password"
    Password unchanged.
    does anyone know about this...? how to change the password..?

    You may be using operating system authentication to log in as sys with sysdba privileges.
    By using password utility, you can change the password of sys user (which is in database) which is "change_on_install" when you create a database.
    You can change this password.

  • Connect DB - SYS user with wrong password

    Hi All,
    A strange thing I have noticed with SYS user since Oracle 9i(never worked on earlier versions) is that I can connect to the SYS user as SYSDBA with wrong password as well! Please guide how to prevent this...
    (I have searched for a solution online but was unable to find any :( )
    SQL> CONN SYS/AAA@TEST AS SYSDBA
    Connected.
    SQL> DISC
    Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production

    Connected.
    SQL>
    SQL> DISC
    Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production*009*

    There is nothing wrong and nothing should be, IMO, prevented.
    When you log in to the server as an user in the dba group (Unix) or the ora_dba group (Windows), you are a power user and O/S authentication applies to you, and you don't need a password.
    Logging in as owner of the software (oracle) all the time, what many DBAs do, is a bad idea anyway, as you can remove anyufile on O/S level.
    Strategies to prevent this:
    - make sure your account isn't in the groups I mentioned
    or
    - disable O/S authentication by editiing sqlnet.ora
    Both procedures are documented.
    Finally please note anyone who has root access can get around this easily.

  • Unable to connect using connect string in linus using sys user in Linux

    Hi,
    I am facing problem in using connect string while connecting as sys user in Linux OS
    For example:
    When I am connecting as
    sys/sysoracle as sysdba its getting connected.
    But when I am providing the connect string such as sys/sysoracle@TEST as sysdba its showing with error as:
    ORA-12505: TNS :listener does not currently know of SID in connect descriptor
    Any help will be benefitial for me
    Thanks and Regards

    >
    ORA-12505:
    TNS:listener does not currently know of SID given in connect descriptor
    Cause:     The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a SID for an instance (usually a database instance) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
    Action:     
    - Wait a moment and try to connect a second time.
    - Check which instances are currently known by the listener by executing: lsnrctl services <listener name>
    - Check that the SID parameter in the connect descriptor specifies an instance known by the listener.
    - Check for an event in the listener.log file.>
    So are you sure that TEST is a right connection string that you are using and is rightly configured?

  • Connect as sys user as sysdba using vbscript

    Hi I have to connect to the oracle database using sys user as sysdba using a vbscript.
    I have the following part in the script:
    Const TARGET_CONN = "DRIVER={Microsoft ODBC for Oracle};SERVER=XYZ;UID=sys;PWD=abc;"
    Set conn = CreateObject("ADODB.Connection")
    conn.Open TARGET_CONN
    When i run the script i get the error: connection as SYS should be as SYSDBA or SYSOPER
    Does anybody know how to do resolve this?
    Thanks in advance.

    Hi,
    If you were using Oracle's ODBC driver, you'd add "as sysdba" as part of the password, ie:
    "DRIVER={oracle in oradb11g_home1};dbq=XYZ;UID=sys;PWD=abc as sysdba;"
    However, you're using Microsoft's driver and I wouldnt be surprised if Microsoft's driver doesnt support it. If it does though, I'm not sure what you need to do.

  • Can't use voice/video functionality with external domain connected users through federation

    Hello All,
    Hope you keeping well..!!
    We are communicating with external customers lync server through federation option setup on our corporate lync server.  We have received the federation setting from the customer with SIP address which has been setup on our corporate lync servers after
    that we were able to browse the customer contact through corporate lync account.
    We were also able to chat with external customer but however voice/video functionality are not working through same session.  Whenever we try to dial out external customer lync account it ended with error message "call ended due to network issue".
    We have checked the setting from corporate lync servers and network point of view but doesn't find any issue which cause the disconnection to voice/video over lync.  Could you pl help or guide with the way to resolve the issue.
    Thanks, MK

    Thanks for your reply.<o:p></o:p>
    Audio/Video works fine within corporate when dial any lync contact.  We only have issue while trying to use the same functionality with any other
    external lync contact configured over federation option.<o:p></o:p>
    We already checked the security rules and all required ports are open, as confirmed by local resolver group.<o:p></o:p>
    We have checked with external parties and according to them their systems are hosted by Microsoft as part of office 365 suite and they already have
    federation option for 17 different customers which works fine.  Which means issue must be your local end.<o:p></o:p>
    Is there any tool available to identify the issue from client end?<o:p></o:p>
    Also I have a question here....In my corporate environment...client is sitting in India and lync servers are hosted in UK and users connect to it
    over MPLS route.  In Client lync configuration we have  internal/external servers configured .....so when i tried to make a voice call with external lync users then I see from netstat -a command that traffic hitting to multiple public IP addresses
    directly from my machine..<o:p></o:p>
    Does it mean that client required internet connectivity with specific open media ports to connect with external parties for video/voice? or in ideal
    case all request should handle by corporate internal server which should took UK internet path to connect with external lync contact?
    Thanks, MK

  • Installing OEM 10g (10.2.0.1) Grid Control on Linux86

    Hi friends,
    I have successfully installed OEM Grid in our RHEL 4.6 server (1st time).
    At the end of the installation I got this message:
    See below for information pertaining to your Enterprise Manager installation:
    1. Use the following URL to access the Enterprise Manager Grid Control:

    How do I access #2? what is the URL corresponding to it? Or is it done through SQLPlus?
    Thanks a lot,
    Ms K

    Thanks Raj,
    Of course I will upgrade it, but for now I am still cramming on how to complete my installation huhuhhu:(
    Firstly....
    How do you install management agent for linux86?
    I have already installed OEM 10g Grid Control OMS on my linux sever which also has EBS R12.1.
    Do I need to install a "management agent" on this server, to be able to manage my EBS R12.1?
    Secondly....
    I want to manage our EBS 11i which resides on another server (remote).
    I downloaded the Linux_Grid_Control_agent_download_10_2_0_2_0.zip file from OTN,
    and put it to the target server.
    I unzip it following the readme.txt to the
    1. Download the Linux_Grid_Control_agent_download_10_2_0_2_0.zip file from OTN.
    2. Copy the downloaded file to <OMS_HOME>/sysman/agent_download/10.2.0.2.0 directory.(create <OMS_HOME>/sysman/agent_download/10.2.0.2.0 directory, if it doesn't exist.)
    3. cd <OMS_HOME>/sysman/agent_download/10.2.0.2.0
    4. <OMS_HOME>/bin/unzip Linux_Grid_Control_agent_download_10_2_0_2_0.zip
    5. If agent_download.rsp doesn't exists at <OMS_HOME>/sysman/agent_download/10.2.0.2.0 directory then:
        a. mv agent_download.rsp.bak agent_download.rsp
        b. edit agent_download.rsp and modify s_OMSHost="%s_hostname%" and s_OMSPort="%s_OMSPort%" with the correct OMSHost and OMSPort values.(However, even if you are specifying a secure Management Service, you must still enter the non-secure port number here)
            eg. s_OMSHost="stadv26.us.oracle.com"
                s_OMSPort="4889"
    6. Edit <OMS_HOME>/sysman/agent_download/10.2.0.2.0/linux/agentDownload.linux and modify OMShost=%s_OMSHost% and httpPort=%s_OMSPort% with the correct OMSHost and OMSPort.(However, even if you are specifying a secure Management Service, you must still enter the non-secure port number here)
       For eg. OMShost =stadv26.us.oracle.com
               httpPort=4889
    7. Follow the agentDownload instructions from 5.4 section of Oracle Enterprise Manager Installation and Basic Configuration Guide.But when I got to #7 ....the documentation is not clear, as usual there are lots of injected unrelated topics which make the documentation "topsiturvy" and very hard to follow.
    Can you just tell me, based on your experience how to install the agent? Someone told me to run OUI?
    But I can not find it on the unzip >Linux_Grid_Control_agent_download_10_2_0_2_0.zip file
    Thanks a lot.
