"Perform whole database Recovery" Host Credentials problem

Hello,
I have minimal knowledge of the Oracle database system but currently I need to recover a Oracle 10G database on a Windows Server 2003 Standard edition.
Im trying to use the Oracle Enterprise Manager. Im logged into the instance with SYS as SYSDBA. On the Perform Recovery page there are fields for "Host Credentials" Could someone explain to me what credentials EM is asking for. Whatever account I try to use EM gives a Validation Error stating
Error - Connection to host as user test failed: ERROR: Wrong password for user
Ive tried both local and Active Directory accounts that have full admin rights on the Host machine. With the AD account I tried using just the user name and allso domain\username. The page asks for "To perform recovery, supply operating system login credentials to access the target database." which sounds like the account has to have both access to the host and the database. Does that mean I have to create an external account in the instance? I even tried that but im not sure I configured it properly.

Well found the solution. Atleast to this problem. Had to give the account "Log on as batch job" rights under Local Policy -> User Rights Assignment

  • Object Level Recovery or Whole Database recovery

    I'm hoping someone may know how to advise me on the following;
    On a datawarehouse db (10.2.0.1.0) a team member removed records from three tables, and I have since attempted flashback recovery without success. The database is in Archivelog mode, with Flashback enabled, but no Flashback logging enabled. The rows were removed on Friday afternoon (it is now Monday). I attempted to get flashback logging enabled by tagging the "Enable Flashback Database" tag in the Flash Recovery region of Recovery settings, and restarting the database. The database when restarted went into mount state, and subsequently on restarting (from mount - I did not dismount the db), it still has Flashback logging disabled. I attempted flashback again but the team member states the record stil arn't there. EM however had given the message 'The select tables...X X....have been flashed back'. However I can see also that Em says flashback logging is still disabled.
    I now consider I might be better off to perform a 'Whole Database Recovery', as I simply want to get the tables recovered. I'm not sure if this will mean re-keying though. Can anyone advise? Thanks in advance. DW

    The first step you should try is flashback query. Because using flashback query your database will remain intact, you don't lose anything from your database. Of course most likely it's too late for you now. Just for future reference.
    Flashback database is only available after you configured Flash Recovery Area and turn it on. Sound like it's does apply here as well. Remember even you could successful flashback your database to the point before deletion, you will lost all data changes after that point. Flashback database only buy you sometime, because you don't need to restore datafile from backup.
    The third option would be restore from your last backup, ( the latest one before deletion happen) and do incomplete restore to the point in time right before the incident.

  • Recovery host credentials error...

    When I try to perform a recovery (click on the Perform Recovery button), on the first page it required me to enter the Host Credentials and Database Credentials in order to proceed.
    Once I have key in both, it direct to another page where it ask for reovery selection. And below the selection there is another Host Credentials.
    But when i enter the Host login again this time, it prompt me the following message.
    ERROR: The specified host user is not a member of the operating system DBA group. The host user must be a DBA group member since the database user does not have the SYSDBA role.
    Isn't it the Host login I enter in the first place same as second Host Login? Anyway there should be one Host Credentials only rite? How can I check and resolve this problem ? I'm Using 10g EM.
    Thanks

  • Host Credentials problem

    I am trying to 'Export to Export file' some individual schemas. I will take this information to a test/development server and import it there to work on.
    When prompted for the Host Credentials I have problems. I am logged on as the Administrator of the domain and I am using these same credentials here only I get one of 2 different error messages.
    1) When I use the credentials of
    Username: Administrator
    Password: admin_password
    I get
    -- Examine and correct the following errors, then retry the operation:

    This is on Windows 2003 server.
    Any suggestions would be apprecitated.

    Ok. Could you check if the DBConsole Service is started as a Domain User or as a Local User.
    My guess is that yoiu are facing the same problem as this thread. Check the solution to it. If it is not the same, then let me know.

  • Enterprise Manager Host Credentials Problem on Windows Vista

    I have similar problem as discribed here before, but the difference is, that I am using Windows Vista and I have tried "Log as a batch job" and "Log as a service" privilleges. It does not help. I have Oracle Personal Edition 10.2.0.3 on Windows Vista. May there be some other security issues on Vista? The error message is not "Wrong password for user" but simply "Error" with no explanation.

  • Host credentials problem in Vista Basic

    Dear All,
    I am using Vista basic OS. I have installed Oracle 10g. I have to use import functionality to import the data. In order to use that in enterprise manager,It asks to enter Host credentials. I tried with DBA credentials, It gives invalid password error. I also tried to add ora_dba group,but unfortunately I cann't add in vista basic as it doesn't support adding Local security group snapin. So please help me how and where to add host credential in order to access import functionality in enterprise manager.
    Thanks in advance.
    Regards,
    Sangamesh

    Helllo,
    As you already know Vista basic and home premium not supported but you can give a try by going to
    First create a user with a password (hope you can do this vista basic)
    control panel --> adminstrative tools--> look for local security policy (if it exists in vista basic) --> local policies and search for user assignments--> log on as a batch job , add your new user and apply changes. Then use this new user as host credentials.

  • Problem in performing multiple Point-In-Time Database Recovery using RMAN

    Hello Experts,
    I am getting an error while performing database point in time recovery multiple times using RMAN. Details are as follows :-
    Environment:
    Oracle 11g, ASM,
    Database DiskGroups : DG_DATA (Data files), DG_ARCH(Archive logs), DG_REDO(Redo logs Control file).
    Snapshot DiskGroups :
    Snapshot1 (taken at 9 am): SNAP1_DATA, SNAP1_ARCH, +SNAP1_REDO
    Snapshot2 (taken at 10 am): SNAP2_DATA, SNAP2_ARCH, +SNAP2_REDO
    Steps performed for point in time recovery:
    1. Restore control file from snapshot 2.
         RMAN> RESTORE CONTROLFILE from '+SNAP2_REDO/orcl/CONTROLFILE/Current.256.777398261';
    2. For 2nd recovery, reset incarnation of database to snapshot 2 incarnation (Say 2).
    3. Catalog data files from snapshot 1.
    4. Catalog archive logs from snapshot 2.
    5. Perform point in time recovery till given time.

    1. Why did recovery failed 2nd time, but not 1st time and why is RMAN looking for online redo log group_1.257.807150859 in 2nd recovery ?
    3. I tried restoring control file from AutoBackup, in that case both 1st and 2nd recovery succeeded.
    However for this to work, I always need to keep the AutoBackup feature enabled.
    How reliable is control file AutoBackup ? Is there any alternative to using AutoBackup, can I restore control file from snapshot backup only ?
    4. If I restore control file from AutoBackup, then from what point of time/SCN does RMAN restores the control file ?
    Please help me out in this issue.
    Thanks.

    Hello experts,
    I'm little newbie to RMAN recovery. Please help me in these doubts:
    1. If I have datafiles, archive logs & control files backup, but current online REDO logs are lost, then can I perform incomplete database recovery ?yes, if you have backups of everything else
    2. Till what maximum time/scn can incomplete database recovery be performed ??Assuming the only thing lost is the redo logs, you can recover to the last scn in the last archivelog.
    3. What is role of online REDO logs in incomplete database recovery ? They provide the final redo changes - the ones that have not been written to archivelogs
    Are they required for incomplete recovery ?It depends on how much incomplete recovery you need to do.
    Think of all of your changes as a constant stream of redo information. As a redolog fills, it is copied to archive, then (eventually) reused. over time, your redo stream is in archivelog_1, continuing into archvivelog_2, then to 3, and eventually, when you get to the last archivelog, into the online redo. A recovery will start with the oldest necessary point in the redo stream and continue forward. Whether or not you need the online redo for a PIT recovery depends on how far forward you need to recover.
    But you should take every precaution to prevent loss of online redo logs .. starting with having multiple members in each redo group ... and keeping those multiple members on physically separate disks.

  • Host Credential Problem in Oracle 10g on Windows

    Hi,
    I have another problem that is really bothering me. I
    have tried using Oracle database 10g on Windows XP and
    it works fine till you shut down and attempt to
    restart (or any administrative task)with the EM. It
    asks for the Database and Host credentials but always
    rejects the Host credentials. Now because i only have
    the Administrator as the OS user, i try to give this
    user and it's password and it still doesn't accept
    that.
    What could be the problem??? I infact have realized
    that this problem is NOT there if i use 10.1.0 on Red
    Hat Linux AS 3 because for the host credentials i use
    the OS user Oracle and the password (Owner of Oracle
    Installation)and it goes through fine.
    In Windows, what should i do to rectify this problem.
    Or is it a bug with Oracle on Windows. Or where should
    i get the relevant Host credentials Oracle requests on
    Windows or should i create a user??? Please
    HELP!!!!!!!!!!

  • Host Credentials to perform recovery

    Hi,
    I prepare for the oca exam, trying to perform recovery in enterprise manager at windows7 os.
    the DB in mount mode.
    in OEM, I click on "perform Recovery" from the home page.
    it ask for host credentials. I get "ORA-01031: insufficient privileges".
    when the DB is open for other alternatives, I don't have this problem.
    I tried to save preferred credentials, which still did not work.
    what is the problem, why I can not login in mount mode?
    thanks.

    Hi,
    since you are getting a read error, it might as well be, that your datafile is defective.
    Try the same dd-command to /dev/null, to see if it is possible to read the entire file.
    First make sure that your null-device is existing, otherwise you might face a root-fs full problem.
    dd obs=1024K bs=1024K if=/oracle/ANP/sapdata2/sr3_9/sr3.data9 of=/dev/null
    or try a dbverify on it, which would also read the entire file and do a checksum test.
    brbackup -c -u / -m /oracle/ANP/sapdata2/sr3_9/sr3.data9 -t online -w only_dbv
    Good luck

  • Use of host credentials.

    Hi,
    Please can u educate me on the above named subject.Anytime i want to perform an action that requires the use of host credentials e.g.performing recovery or importing data,it brings out an unspecified error thereafter stopping the enterprise manager from working. Thanks.

    Hi,
    Any time you need to perform an operation over the OS, the OEM will request the Host Credentials (OS Username and password/e.g. user: Oracle, Password: xxxxx) to execute your request because when you connected to the web console you only enter the DB Username and password not the OS ones. That mean the OEM don't have the information necessary to connect to the OS to write something to disk, or execute something over the OS (Backup, recover,etc).
    If you are using linux/windows the hostname credentials should be the user who has installed the oracle 10g database software, if Windosw the user you are using need to be member of the ora_dba group and have Local Security privilege 'Log on as a batch job'.
    What you need to do is go to start----> Programs----> admin tools----> Local security policy --->local policies ---> user rights assignments
    In the list to your right, look for 'Log on as a batch job', double click and add the same OS local user you using to access OEM web to the group.I hope this answer your question. You can always say to the OEM to save your OS username and password, this way you are not going to be asked all the time.
    Cheers,
