Create Standby DB with diff Dbname

Hi all,
10g
I want to create a standby db "PROD" to another server. But the problem is that there is also and exising "PROD" instance in that server :(
Can I create it using different name like "PROD2"?
Thanks a lot,
zxy

DB_NAME should be same with primary DB but you can change DB_UNIQE_NAME as compared to primary DB
The DB_NAME parameter should be identical on both primary and standby databases. However, you need to change the db_unique_name parameter for primary and the standby database. DB_UNIQUE_NAME parameter should not be identical and you may set it like;
Primary:
DB_NAME=ORCL
DB_UNIQUE_NAME=ORCL
Standby:
DB_NAME=ORCL
DB_UNIQUE_NAME=ORCLSTB
dbname in standby database

  • On the AGO Function need to Create TODATE function with Diff levels - MTD,Q

    Hi All,
    My Basic Requirement is to Create Time Series Function on AAA ie ( Month To Date , Quarter To Date and Year To Date )
    The Logic for the AAA = XXX / Previous 3 Months Revenue.
    we know that we can use the AGO Function to create Previous 3 months Revenue with Month is Level . But the issue is .... i cant use AGO function since i need to perform Year to Date, QTD and MTD upon 'AAA' this OBIEE doesn't permit to use nested time series functions upon varying levels .
    So How can i Resolve the issue ie creation of TODATE function on the AGO Function with Diff levels
    Thanks,
    Swapna S

    hi,
    for your requirement create three repository variables like
    for previous 3 months create repository variable like
    select to_char(sysdate,'yyyymm') -3 from dual;
    for month to date first calculate first day of the month
    select To_Char(Add_Months(Last_Day(Sysdate),-1) + 1,'MM/DD/YYYY') from dual;
    after put a filter in answers date between first date of the present month and current date
    create the same thing for year to date
    calculate first date in the year like following query
    select To_Char(Trunc(Sysdate,'YEAR'),'MM/DD/YYYY') from dual;
    after that apply filter date b/w first date in the year and current date
    i hope it works for your scenario

  • Creating Standby database with Oracle 10gR2 SE (no dataguard). Procedure

    Hello,
    I have problems in creating a standby database without Dataguard (Oracle Standard Edition)
    -Oracle 10gR2 SE (No DataGuard !!!!)
    - SUSE Enterprise 10.
    Both primary and standby databases are running in Virtual machines (lab).
    I will describe the exact steps I followed :
    1.---------------------------------------------------
    Both primary and standby databases have exactly the same file / folder structure
    2.---------------------------------------------------
    I enabled archive log mode with a new destination : /opt/oracle/oradata/orcl/archive_logs.
    Also : SQL> alter database force logging;
    3.---------------------------------------------------
    I shut down the primary database (shutdown immediate)
    4.---------------------------------------------------
    I created a standby controlfile on the primary database:
    SQL> startup mount
    SQL> alter database create standby controlfile as '/tmp/standby.ctl'
    SQL> shutdown immediate
    5.---------------------------------------------------
    I did a cold backup from the primary db to the standby db
    (I copied all the db files, control files, redo log)
    6.---------------------------------------------------
    I copied from the primary db to the standby db the standby control file
    (from primary /tmp/standby.ctl)
    7.---------------------------------------------------
    I copied from the primary db to the standby db the standby control file
    (from primary /tmp/standby.ctl)
    8.---------------------------------------------------
    I created on the standby database a pfile from the spfile :
    SQL> create pfile from spfile;
    9.---------------------------------------------------
    I edited the pfile and changed the controlfile location (with the standby controlfile created in step 4)
    >>>>> *.control_files='/opt/oracle/oradata/orcl/standby.ctl'
    10.--------------------------------------------------
    I started the standby db
    SQL> startup mount pfile='/opt/oracle/product/10.2/db_1/dbs/initorcl.ora'
    SQL> alter database recover managed standby database disconnect from session;

    Hi
    Ref to your Oracle SE Standby issue, we were in similar situation couple of years ago to build an Automated Standby for our disaster recovery on Oracle SE. We finally got a solution provider Anbul Technologies , they have a one of their solutions based on Oracle SE which provided fully automated Standby in Oracle SE.
    We are successfully running that solution in our prod env for many years. You can visit their site www.anbultechnologies.co.uk or contact them for further details. They are Uk based but provides support and services all over Europe.

  • Create standby DB with RMAN backup in Oracle 9.2.0.6

    I am tring to create a standby DB in different host with different directory using RMAN. The commandv with which I tried to create the standby database is the follow:

    RELEASE CHANNEL ch00;
    when $BACKUP_TYPE=0
    Can anyone help my with this problem?? Thaks
    Cristian.
    PS. Sorry my bad english because I am from Latin America

    Requirements are:
    1 the backup should be accessible to both target and auxiliary database in the same location.
    2 On Unix this can be arranged through NFS, provided you set the read and write buffer to 32k.
    Obviously the backup can not be located in $ORACLE_HOME/dbs, as you can not mount a NFS directory over $ORACLE_HOME/dbs without loosing functionality.

  • Problem creating physical Standby database with RMAN

    Hi All
    I am trying to learn oracle dataguard and as part of the process learning creating standby database.
    Platform : Sun-Fire-V250 Sparc, Solaris 10
    Database Version - Oracle 11R2
    I am creating standby database on same server, so directory structure is different.
    Following the instructions on Oracle site I managed to create a functional physical standby database. But I am not able to create standby database using RMAN. These are the steps that I followed-
    1.Set up all necessary parameters on primary database as done while creating physical standby database manually, eg setting force logging, creating standby logs etc.
    2.Edited parameter file on primary database as done while creating manual pysical standby database creation. Some of the changes done are-
    On Primary Database:
    *.FAL_CLIENT='orcl11020' #Primary database unique name
    *.FAL_SERVER='stdby_11' #Standby database unique name
    db_file_name_convert='/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020'
    log_file_name_convert='/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11/redo_mem','/<dir>/oradata/orcl11020/redo_mem'
    standby_file_management=auto
    *.log_archive_config='DG_CONFIG=(orcl11020,stdby_11)'
    *.log_archive_dest_1='LOCATION=/<dir>/flash_recovery_area/ORCL11020/archivelog
    VALID_FOR=(ALL_LOGFILES,ALL_ROLES) db_unique_name=orcl11020'
    *.log_archive_dest_2='SERVICE=stdby_11 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) db_unique_name=stdby_11'
    *.LOG_ARCHIVE_DEST_STATE_1='ENABLE'
    *.LOG_ARCHIVE_DEST_STATE_2='ENABLE'
    *.LOG_ARCHIVE_FORMAT='%t_%s_%r.arc'
    *.LOG_ARCHIVE_MAX_PROCESSES=30
    Copied same pfile for standby database and modified following-
    *.control_files='/<dir>/oradata/stdby_11/stdby_11.ctl','/<dir>/fra_stdby/stdby_11/stdby_11.ctl'
    *.db_name='orcl1102'
    *.db_unique_name='stdby_11'
    *.FAL_CLIENT='stdby_11'
    *.FAL_SERVER='orcl11020'
    db_file_name_convert='/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11'
    log_file_name_convert='/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020/redo_mem','/<dir>/oradata/stdby_11/redo_mem'
    standby_file_management=auto
    *.log_archive_dest_1='LOCATION=/<dir>/fra_stdby/STDBY_11/archivelog
    VALID_FOR=(ALL_LOGFILES,ALL_ROLES) db_unique_name=stdby_11'
    *.log_archive_dest_2='SERVICE=orcl11020 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
    db_unique_name=orcl11020'
    3. Add relevant information in tnsnames.ora and listener.ora files and then restart listener.
    3. Created password file with same credential as primary database.
    4.Up-to-date RMAN backup of primary database available.
    5.Create standby controlfile with rman
    While primary database s open (I tried with primary database in mount mode as well)-
    $>rman catalog rman/paswd@rman target /
    RMAN> BACKUP CURRENT CONTROLFILE FOR STANDBY;
    6. Open a new terminal and startup standby database in nomount mode using parameter file created -
    $>ORACLE_SID=stdby_11
    $>export ORACLE_SID
    $>sqlplus / as sysdba
    SQL>STARTUP NOMOUNT pfile='<location/initfilename.ora'
    SQL>quit
    $> rman AUXILIARY / target sys/passwd@orcl11020 catalog rman/passwd@rman
    RMAN>DUPLICATE TARGET DATABASE FOR STANDBY DORECOVER;
    RMAN finishes without error but archive logs are not being tranported. Looking at the log, following caught my eye-
    Error 1017 received logging on to the standby
    Check that the primary and standby are using a password file
    and remote_login_passwordfile is set to SHARED or EXCLUSIVE,
    and that the SYS password is same in the password files.
    returning error ORA-16191
    FAL[client, ARC2]: Error 16191 connecting to orcl11020 for fetching gap sequence
    Errors in file /<>dir>/diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
    ORA-16191: Primary log shipping client not logged on standby
    Errors in file /<dir>/diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
    ORA-16191: Primary log shipping client not logged on standby
    So on both primary and standby I confirmed
    SQL> show parameter remote_login_passwordfile
    NAME TYPE VALUE
    remote_login_passwordfile string EXCLUSIVE
    To make double sure that password files are same, I shutdown both databases, delete password files and recreated with same credentials.
    Password files are called - orapworcl11020 and orapwstdby_11
    Can someone guide me where thisngs are going wrong here please.

    Not sure if I understood it clearly.
    SELECT * FROM V$ARCHIVE_GAP;
    returns no rows so there is no gap.
    But could you please explain me the result of the previous query. To catch up again, on standby when I check
    SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG
    SEQUENCE# APPLIED
    75 NO
    74 NO
    76 NO
    77 NO
    I understand that though archive files have been copied across but they are not applied yet.
    On primary when I give your query -
    SELECT name as STANDBY,SEQUENCE#,applied, completion_time
    2 FROM v$archived_log
    3 where dest_id=2
    4 and sequence# BETWEEN 74 and 80;
    I get -
    STANDBY SEQUENCE# APPLIED COMPLETIO
    stdby_11 74 YES 28-JUN-11
    stdby_11 75 YES 28-JUN-11
    stdby_11 76 YES 29-JUN-11
    stdby_11 77 YES 29-JUN-11
    stdby_11 78 YES 29-JUN-11
    stdby_11 79 YES 29-JUN-11
    stdby_11 80 YES 29-JUN-11
    stdby_11 75 NO 07-JUL-11
    stdby_11 74 NO 07-JUL-11
    stdby_11 76 NO 07-JUL-11
    stdby_11 77 NO 07-JUL-11
    stdby_11 78 NO 07-JUL-11
    I have intentionally given
    sequence# BETWEEN 74 and 80
    because I know in the current incarnaion of the database, max sequence is 78.
    So my understanding is, the rows between 28-29 June are from previous incarnation, correct me if I am wrong
    Archive files of the current incarnation, since I successfully created standby database are shipped but yet to be applied - am I right?
    Then my final question is, when will these archives be applied to standby database?
    I am sorry to ask too many questions but I am just trying to understand how it all works.
    Thanks for your help again

    Looks like very difficult and inform you mgmt about the drawbacks of running olderv ersions
    may be you can try something like this but i dont know whether it is supported or not
    db_file_name_convert=['/dev/vx/dsk/suportaldg/oracle3','/dev/vx/dsk/suportaldg/STDBY/oracle3']

  • Creating standby database using RMAN

    When I'm creating standby database with RMAN command
    'duplicate for standby' backups for creating standby database
    have to be accessible from host where standby database
    is created. I can copy the backups to standby host, or use
    NFS to share the disk with backups to standby host.
    But when I have backups in ASM diskgroup how can
    I achieve it would be accessible from standby host?
    Thanks a lot for advice,
    M.

    OK, thanks,
    I will create standby using Grid, but I have the following problem:
    database instance is running on the host where I want
    to create standby database. The running instance is for
    testing purposes and has the same db_name, db_unique_name, db_domain
    parameters as in primary database.
    I will change db_unique_name to be distinct from primary database one,
    should I also change instance SID not to be the same in
    testing database and standby on the same host, or when creating standby
    database I can specify distinct one for standby database?

  • Creating a Standby Database with the Same Directory Structure

    Hello gurus,
    I am self-learning the feature Oracle Data Guard, so I am testing it on Oracle 10g R2.
    At Oracle documentation there is a section F.4.: Creating a Standby Database with the Same Directory Structure*, that explains how to create a standby database with RMAN but there is something that I don´t understand:
    In the standby server, I created a database with the SID equal to production database* with the objetive to have the same directory structure, but when I try to startup nomount the standby database with pfile appear this expected error:
    ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes
    So my question is: Is possible have the Same Directory Structure on both: Production and StandBy server?
    Thanks in advanced.

    Uwe and mseberg: thanks for your quick answers
    I have a doubt: How can you have the same directory structure if you have differents SIDs?, for example if you follow the OFA suggestions you would must have:
    On Production server: */u01/app/oracle/oradata/PRIMARY/system.dbf*
    On StandBy server: */u01/app/oracle/oradata/STANDBY/system.dbf*
    Or you created the directory structure manually on StandBy server? For example replacing the string STANDBY* to PRIMARY* before create the database using dbca.
    Do you understand my doubt? Excuse me for my english.
    Thanks.

  • Error - when creating a standby database with EM 10g Grid Control

    Hi,
    I am experiencing some problems when I want to create through the EM 10g Grid Control a standby database from a allready existing db. At step 2 when the files should be generated and copied to the other system, I am always getting the error that there isn't enough disk space on the other system. This can't be because there is at least 30GB free and the installer is asking for less than 1GB. I was searching the whole internet for a solution to this issue, but there was just nothing that could help me out with that point...
    Has someone an idea at this point? Thanks for helping...
    I am working on a Windows 2003 Server - Enterprise Edition for every system (Grid Control, Primary DB and Standby DB).
    Best regards,
    Patrick.

    Check that filesystem space using GC under targets>hosts on which you are trying to create standby. Do you have any specific error message from GC ? If GC shows proper size under host filesystem section then there shuld be no such problem. Double chk ur locations too.

  • What are the differences of creating a physical standby database with ASM?

    I want to create a physical standby database for my 10g(10.2.0.1) database. But it is using ASM. Is it possible to create a standby database for a database using ASM?
    What are the differences of creating a physical standby database with ASM?

    tell us what your research shows and we'll try to
    validate it. I am simulating Oracle ASM on a PC and I want to try
    DataGuard on it now. So I am trying to create DataGuard
    on an ASM system. The purpose is only learning and test.That's telling us how you are researching, not what you have observed.
    Your research could have included looking at the documetation, and you might have found http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/scenarios.htm#sthref1642
    which discusses exactly what you are looking for.

    I am creating a standby database with active database option (without any backups). When i am checking number of connections in my primary database, i can see 3 rman connections
    from the standby machine. How oracle reaches to a conclusion of 3 sessions ? Is this number fix or this number can be manipulated with requirment ?

    Check for the RMAN parallelism in standby database it might be set to 3.

  • How to manually create a standby db with SAN for hardware cluster failover

    Hi all,
    The primary db(oracle 9i r2, Sun Solaris) puts its datafile, redo logs, control files in SAN while the pfile, listener and tnsnames files are in its local hardisk. I need to create a standby db(not for dataguard) for hardware cluster failover, where if the primary db fails the hardware cluster will failover to standby db(mounting the datafile, redologs, control files in
    SAN to a mount point automatically and start the db services). But I don't know how to create the standby db, I would install the db software first then should I copy the pfile(created from primary db), listener and tnsnames files to standby db? What are the correct steps to do it? Any advice is greatly appreciated.

    Thanks ackermsb for the reponse. I think I have confused of setting standby db and creating a HA. What I trying to achieve is creating a HA with vendor clusterware and oracle e.g. Sun Cluster HA for Oracle.
    The steps involved in preparing the primary and standby oracle are:
    Oracle application files – These files include Oracle binaries, configuration files, and parameter files. Need to installed separately in two servers locally.
    The Database-related files – These files include the control file, redo logs, and data files are placed in a Cluster File System.
    What I don't how to do it is, after installing the oracle binary in standby server, should I create the listener, tnsnames and pfile or copy them from the primary db?
    Thanks in advance.

    Are you trying to change the iCloud ID on your phone?
    Also, you can change your iTunes ID by going to Settings>iTunes & App Store, tap the ID, sign out, then sign back in with the ID you want to use.

  • Problem with create standby by rman oracle9.2

    Additional information: 349248
    The scripts are ok becouse they work earlier.
    The main database was a standby but now is primary.
    I create new standby base on remote server
    I have in bdump strange error for me until create rman copy for standby:
    Clearing standby activation ID 1004670785 (0x3be20f41)
    The primary database controlfile was created using the
    'MAXLOGFILES 5' clause.
    The resulting standby controlfile will not have enough
    available logfile entries to support an adequate number
    of standby redo logfiles. Consider re-creating the
    primary controlfile using 'MAXLOGFILES 8' (or larger).
    Use the following SQL commands on the standby database to create
    standby redo logfiles that match the primary database:
    ALTER DATABASE ADD STANDBY LOGFILE 'srl1.f' SIZE 409600000;
    ALTER DATABASE ADD STANDBY LOGFILE 'srl2.f' SIZE 409600000;
    ALTER DATABASE ADD STANDBY LOGFILE 'srl3.f' SIZE 409600000;
    ALTER DATABASE ADD STANDBY LOGFILE 'srl4.f' SIZE 409600000;
    Any suggestions?
