Oracle 10g XE - unable to connect to the database home page

Hi,
I have installed Oracle 10g XE on my computer. When I try to open the Database home page at http://127.0.0.1:8080/apex, I get a Page not found error.
I have followed the steps outlined in the forums-
a) did "netstat -a"
Output : found that port 8080 isn't being used.
b) did "lsnrctl status"
Output: under Services summary - instance "CLRExtProc" is unknown
- instance "PLSExtProc" is unknown
- instance "xe" is ready
- instance "xe_xpt" is ready
c) did "sqlplus / as sysdba"
Output : Connected to Oracle 10g Express Edition
d) did "select status from v$instance "
Output : Mounted
e) did "select open_mode from v$database"
Output : Mounted
f) did "startup"
Output : started the database
Not sure why the database home page still wouldn't open. Any help is appreciated.

Hi,
>>What is the command to change the status to "READ WRITE" ?

  • "Unable to connect to the database" when connected to corporate network

    Hi
    Installed Primavera P6 V7 and Oracle 10g in Stand alone on XP 32bit machines with SP3. When our machines are NOT connected to the corporate network it works fine.
    However when connected to the network we can not access the locally stored database. We get message "primavera unable to connect to the database. would you like to configure the database connection now"
    Database on servers that we set up are fine regardless.
    If we connect machines to just the internet, again no issues.
    So something is stopping Primavera opening local database when connect on our corporate network.
    Any ideas please?
    Thanks

    This may be a long shot but look into how your TNSNAMES.ora file is being distributed on the domain (or are you possibly utilizing LDAP.ora on the domain side?).
    Some time ago I remember a company scripting an ENV variable on domain logon that altered where the Oracle client would pull the TNSNAMES from.

  • Unable to Connect to the database in RCU, Oracle11g XE on Laptop/Windows

    Software downloaded unzipped and installed from OTN
    OBIEE foundation 11.1.1.5
    Repository Creation Utility 11.1.1.5
    Oracle Database Express Edition 11.2
    Issues
    1. I installed Oracle 11g express edition. I am able to start/stop and run sql against the database however the homepage ("get started " accessed from Start > Programs > Oracle Database 11g XE > Get Started) does not work. This i will post in a separate thread but I am writing this anyway just in case it has some relevance.
    2, This is the one I need help with. Can you confirm that these are the parameters when I hit the "create" option in RCU because I get the error message saying I cannot connect.
    Hostname:This is the same as the hostname, when I go to cmd prompt like below
    C:>hostname<enter> That is what I am using.
    Port and Service :Can you confirm, Port = "1521" and Service = "XE". 1521 is the Database listener port when I installed Oracle 11g Database Express Edition. I am not putting the quotes in the boxes in the RCU.
    Should the service be OracleServiceXE - i have tried it but does not work.
    Anyway I get this message:
    Unable to connect to the database using the provided details.
    Please enter a valid hostname and port or check if the listener is up and running.
    Any ideas appreciated.

    Hi,
    Like Abhi said, check your tnsnames.ora file to check the port number and service name is correct or not for the Express Edition database you have installed.
    and when you are running RCU installer, Please give system adminstrator account of OracleXE like 'sys' or 'system' account with confirmed port number and service name.
    Hope this helps.

  • Unable to connect to the database to product shared services

    Hi
    I got an error in configuring shared services with the Oracle server database
    "" Unable to connect to the database to product shared services ""
    I created a database that is working properly when accessed by a client.
    I typed everything in config utility, Does we need to take care of any other servies?
    I appreciate if any one help with this.
    Thanks

    Version: Hyperion System 9 and Oracle 9i

    John is of course correct that XP is not a supported environment for Essbase 9.3.x.
    Having said that, I have successfully installed Shared Services, Essbase, and EAS on multiple XP laptops. I have done so with 9.2 (painful) and 9.3.1 (just about painless) although always against SQL Server. This is strictly for development/kick the tires work, never as a production environment.
    Planning has quite an issue with XP (and Vista) although I have heard that there is a Windows Registry fix for this.
    Of course Oracle support is going to gong you if you call up with questions about your laptop -- it isn't supported.
    One last thing -- Shared Services and laptop suspends =! stability. For my development purposes, I have backed off Shared Serivces and just go with Essbase as a service with native security and EAS.

    P.S. VMs are probably the way to go if your desktop/laptop has the horsepower to drive a proper OS with the VM overhead. On a 4 gigabyte laptop with a Duo Core (no, not a Mac, I just can't remember what Intel calls it -- the power of marketing) VMServer running Windows Server 2003 and the full stack is pretty slow, but it works.

  • INS0009: Unable to connect to the database with user SYS

    Hi all,
    I'm trying to create an OWB repository with OWB repository assistant (10.2.0.2.) on a 10.2.0.1. database (windows XP platform). I get the following error every time I fill in the connect info for the SYS user:
    INS0009: Unable to connect to the database with user SYS. java.sql.SQLException: ORA-01017: invalid username/password; logon denied
    I can connect to the database (sqlplus sys/<password>@orcl as sysdba) and the OS user is in the ora_dba group. Also checked the database parameters remote_login_passwordfile (= EXCLUSIVE) and O7_DICTIONARY_ACCESSIBILITY=TRUE.
    Does anyone know what the problem is? Any help is appreciated.
    Regards,
    Quinten

    Ok I found the problem myself, I used the wrong sys password :-(. I thought the password I used to logon in sqlplus was right (sqlplus sys/<password>@orcl as sysdba) but the password doesn't matter when you logon as sysdba! So I altered the password for the user sys and now I can continue the steps of the repository assistant.

    Well, that's an old version of SharePoint! That database is the name of the configuration database for your deployment. This may have to do with the Timer Service.
    Can you check this kb to see if it's of any use for you?

  • REG: Unable to connect to the database

    Hi All,
    I have installed mdm 7.1 sp06 on one server  with database as SQL on other server, was able to mount the server and running fine but when trying to connect to the database using the user sa, giving the error "Unable to connect to the database server".
    Can any one please help in how to connect to the database on other server?
    Regards,
    Mounika.

    hello,
    What sequence did you follow.
    the normal sequence is to start the data base server first and then the mdm server.
    Kindly take a restart of the servers and check th mds.ini file for the relevant settings for Database connectivity.
    Mostly the restart will solve the problem, if it still doesnt do let me know
    regards,

  • Can not load the Database Home page

    I have installed the database on a XP sp2 computer. After the installation is complete I try to open the database home page using the short cut created by the installation program and I receive an error from in I.E. “The page can not be displayed”. I tried to connect using the Run SQL command line by typing "connect system/password (My system password create in the installation)" and I receive another set of errors:
    ORA-01034: ORACLE not available
    ORA-27101: shared memory realm does not exist

    Hi,
    did the installation complete without errors?
    Check the logfiles for "ORA-" messages:
    cd D:\Oracle\XE\app\oracle\product\10.2.0\server\config\log
    D:\Oracle\XE\app\oracle\product\10.2.0\server\config\log>grep "ORA-" *
    cloneDBCreation.log:ORA-01109: Datenbank nicht geoffnetThis is what it looks like after my install on XP, the one message is ok.
    What about the user accounts you used for the install?
    Was the install user a local admin user on your machine?
    What does the command net localgroup ORA_DBA say?
    Is the user you are trying to connect to the XE db a member of this local group?
    Here is the output from my machine:
    D:\Oracle\XE\app\oracle\product\10.2.0\server\config\log>net localgroup ORA_DBA
    Aliasname ORA_DBA
    Beschreibung Members can connect to the Oracle database as a DBA without a password

  • Unable to connect to the database instance using Enterprise Manager.

    I just install Oracle 10gr2 in my computer and after successful installation created a database instance which also install successfully. I then configure the listener using Net Manager and then start the database instance, the listener and dbconsole, everything seems to work fine and checking the status of this services from the command prompt indicates everything started successfully. But when I try to use Enterprise Manager I was directed to the Database Down Page with a message unable to connect to database instance. I try to use startup and perform recovery but every time I log-in to the database an error message comes out:
    SQLEXCEPTION
    ORA-00604: error occurred at recursive SQL level 1
    ORA-12705: Cannot access NLS data files or invalid environment specified.
    It seems for Enterprise Manager to connect to the database it needs to access this NLS(National Language Support) data files or specify an environment variable to point to this data files. I am just new to Oracle and I am having difficulty solving this particular problem. Where is this data files located and how do I configure Enterprise Manager to access this NLS data Files?
    Any help however small will be highly appreciated.

    Are you able to connect to the database via SQLPlus?
    What Operating System are you using?
    Assuming Windows, can you RUN regedit to open Windows Registry and check the value or NLS_LANG when you select
    HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_<your_oracle_home>
    Examples of vaules you may find:
    1. ENGLISH_UNITED KINGDOM.WE8MSWIN1252
    2. AMERICAN_AMERICA.US7ASCII
    3. AMERICAN_AMERICA.WE8MSWIN1252
    4. FRENCH_FRANCE.WE8MSWIN1252
    5. GERMAN_GERMANY.WE8MSWIN1252
    If you are not able to connect to SQLPlus, from the command prompt try setting one of the above:
    e.g.
    D:\>set NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
    D:\>sqlplus /nolog
    SQL>connect sysman/password
