I Forgot Oracle XE Password for Database administrator user "system"

Hello,
is there a chance to get my password back for the database administraor account with the username "system" or to reset it otherwise? Unfortunately I have no change to remember it. Is there help for that problem?

If you would like to change password:
you login to sys and then change password of some users if you need
linux:
export ORACLE_SID=XE
export ORACLE_HOME=<ORACLE_PATH>
sqlplus / as sysdba
SQL> alter user system identified by <new_pass>;
window:
set ORACLE_SID=XE
set ORACLE_HOME=<ORACLE_PATH>
sqlplus / as sysdba
SQL> alter user system identified by <new_pass>;

    suresh.m2015,
    It's going to be impossible for anyone in this forum to help with your issue if you don't provide any more detail about your environment and Apex installation. However, from your post it looks like the Apex database objects are missing or invalid.
    Did you follow the Apex installation guide step by step? For example, did you run apexins.sql?
    It's important to follow the documentation. The script you are running to change the admin user password should not be run until after the Apex installation is complete.

  • "You may need to enter the name and password for an administrator"

    I am suddenly getting this message when I try to copy a file from my new Macbookpro to my Powerbook running 10.4.9.
    "You may need to enter the name and password for an administrator on this computer to change the item named "file i am trying to transfer". stop continue
    I hit continue and get the error message: "The item "that I am transferring" contains one or more items you do not have permission to read. Do you want to copy the items you are allowed to read?
    I say continue and get the error: "The operation cannot be completed because you do not have sufficient priveleges for some of the items."
    My network was working fine until today. I can copy fine to all other computers on my network. But not this one.
    If I initiate a transfer from the Powerbook, everything works fine.
    Ideas?

    I experience the exact issue between a macbook pro and an iMac.
    I can access the files locally on my macbook, copy them on usb-stick, etc.
    but ... when I try to copy the files to my iMac ... it fails with the sequence of questions you mentioned.
    However!
    I can copy whatever I like from my macbook if I use my wifes account.
    So...
    Imho there is a problem when the SAME account is used on both systems.
    In my case, I copied my account from the macbook to the (new) iMac.
    Mac OS X seems to be confused when the same accounts are used.
    Does this makes sense?
    All help welcome.

  • PLEASE HELP  Forgot my admin password for os x Yosemite

    hello every one i really need  help. i forgot my admin password and i really need the stuff which is inside can anyone please help??? i already checked online  but i did not get what  i need cuz  of this photo i did cheek the box of resting my password with an apple id.

    Boot from the Recovery Partition and reset your password from there.
    Here’s how:
    1/ Make sure your computer is completely shut down.
    2/ You’ll have to be quick next: Press the Mac’s power button. As soon as you either hear the loud chime, or see the display light up - usually after a second or 2 - on your keyboard press [cmd] + [r] Keep these keys on your keyboard pressed until you either see an Apple Logo with a loading bar or a spinning gear.
    After a few minutes, you’ll be presented with a Utilities screen. This is the Recovery partition. If this step is already giving you problems, try using a USB-keyboard. It doesn’t have to be an Apple-keyboard. If you have a Windows-tailored keyboard laying around, use the “Windows-flag” key in stead of the [cmd]-key and it should also work.
    3/ Find the menu called “utilities” in the top left corner of your computer’s display. It’s in between the menus “edit” and “window” Don’t be confused with the menu called “os x utilities” 
    Choose Terminal. A somewhat old-fashioned looking window will pop up, waiting for a text command from you. This is the Terminal.
    After the # type: resetpassword and press return. Note that there is no space between ‘reset’ and ‘password’ 
    What you’ll see next is an rectangular window that gives you the option to reset passwords. Set a new password for all the users that you need.
    We’re ready to reboot your Mac now. Click on the Apple Menu and choose “startup disk” Choose to boot from “Macintosh HD” Please let us know if this solved your issue, or if the steps above did not work, or could not be performed for some reason.

  • Sneak Preview ABAP - Password for Database Manager Operator Control

    Hello All , My first installation 'SAP NetWeaver 2004s Sneak Preview ABAP' was aborted where I did supply the password for Database Manager Operator Account : Control . When I am trying to reinstall , the installation fails and it comes back with a message
    ' The check of the control user password failed . Check logfile XCMDOUT.LOG '.
    I think I am supplying the correct password which I entered originally .
    Thanks
    Rajesh Kapoor

    hi there,
    the default password for control is control.
    According to about threethousandfivehundredandtwelve postings in here your problem might arise due to the usage of special characters in the password, e.g. a +(plus).
    What do the last few lines of your XCMDOUT.LOG read?
    regards,

  • Pre-requisite for lab setup for database administration track.

    Hi, does anybody know what setup is required to participate in Lab for database administration track on Feb 11?

    The code you have in the rules file looks like it is incorrect. PCon would not be defined automatically and would therefore return zero. I think what you are actually looking for is something like:
    Call Hs.Con ("",HS.Node.PCon(""),"")
    Note that you can determine if the consolidation rules are used from you metadata under AppSettings. Look for the setting called ConsolidationRules. If you set this to Y, it uses the rules under Sub Consolidate(), if you set it N, it will automatically consolidate even if you have nothing under Sub Consolidate().
    Further, you can affect what gets consolidated in the metadata. Some of your accounts etc. may not be set correctly. Some things to check:
    For Accounts, make sure that IsConsolidated is checked and the AccountType is correct
    Also for Accounts, ensure that EnableCustom1Aggr ... is checked
    Finally, if the Entities have different currencies, check if you are getting data up to [Parent Total]. If not, the problem is your translation and not your consolidation.
