• move the primary database files to another location

  Hi all
  
  I move the files of my primary database to another location on the same server, but on a different drive (from f: to G :) with rename comand but file name will be the same, after you have moved the files what step I need to perfom on standby DB will have on my database pending?)

  This doc is everything after you rename the primary file, I'm not rename all the files I need to just move file from one place to another without changing the file name.

  I hope you know how to move files from one place to the other on the primary database. It's not just copying the files from one disk to another and then to go to the top of your database.

  You rename your data files or copy it to another location, how the controlfile to know you have copied/renamed to a different location?

  I guess you 1 to ask the question of how to move files to a different location in primary education and then move on standby.

  Steps to follow:
  1 Hope you brought your primary database.
  2 copy the datafiels to one disk to another.
  3. attach the primary database.
  4 rename all data files that you moved to this control file would know the changes.
  SQL > alter rename file 'G:\oracle\user01.dbf' to 'F:\oracle\user01.dbf ';
  5. subsequently open the database.
  Refer this to move data files from one place to another http://www.orafaq.com/wiki/Move_datafile_to_different_location, http://www.adp-gmbh.ch/ora/admin/move_datafiles.html

  on autonomy in standby:
  1 cancel the MRP
  2. change the db_file_name_convert to point to «F:\»... »
  3. Mount the backup database
  4. start the MRP

  Hope that these steps are clear.

• Migration of data from the old platform to the new primary database, need advice.

  I have physical standby facility and everything works now.
  
  Next weekend, we will do the actual migration of the old platform to the new environment.
  
  I have several issues of concern.
  
  Migration will go to the primary database. I'll have to remove patterns and inside expdp dmp.
  
  While I do all those, what data base waiting? should I disable it again apply?
  
  What other concerns and precautions I need to take before I have to remove all data from primary school and do a migration?
  
  Thank you in advance.

  Hello;

  My main concern would be the FRA (assuming you use it).

  By doing all that generates a ton of archives, you have to worry about the space on both sides.

  I would consider increasing my FRA on both sides.

  I would not disable the recovery, but I look very close and be willing to adjust my space as needed.

  As long as you don't miss space you should be fine. I had once a backup log files more than 250, and it took about 15 minutes to catch up.

  Have a little prepared scripts in advance if you can increase the space or delete archive applied and it should be fine.

  I also opened at least two terminals on the primary and Standby. Everyone look at space and the other to execute all what you need to adjust the space.

  The rest is common sense, first do the smaller drawing if you have an idea what to expect. Decaying etc. as much as possible.

  I have a shell script called 'quickcheck.sh' (use a separate but .env file it will send information vital back)

  With a little work, you can do this in something that makes it easy to keep an eye on things.

  #!/bin/bash
  ####################################################################
  #
  
  if [ "$1" ]
  then DBNAME=$1
  else
  echo "basename $0 : Syntax error : use . quickcheck  "
  exit 1

  # Set the Environmental variable for the instance
  #
  . /u01/app/oracle/dba_tool/env/${DBNAME}.env

• I used to work with Interbase and Firebird and used databases the keyword "domain". I am now switchig to Oracle as a primary database and would like to find an alternative appropriate "domain" in Oracle, as it appears he does ' t taken in charge the stand

  I used to work with Interbase and Firebird and used databases the keyword "domain".

  I am now switchig to Oracle as a primary database and would like to find a suitable

  Variant of 'area' in Oracle such that it appears he does ' t support the standard SQL syntax.

  for example:

  Create the int2 smallint field;

  create domain id2 int2 default 0 not NULL; / * for the primary key * /.

  create domain rel2 int2 default 0 not NULL; / * foreign key * /.

  I tried a couple of approaches to achieve this "area" is:

  1. create synonym - cannot be used with the basic types;

  2. create the type - type of work, but the implementation is rather clumsy

  and can be costly in terms of performance.

  Is there something else to Oracle that can emulate the feature "domain"?

  Thanks in advence, I got really approciate any help on this.

  Alex.

  Your best approximation is CREATE TYPE, but their is nothing of what is a 100% adjustment.

  For example, if you create a domain with a check constraint you need to implement than separately on each table.

• No index on the primary database. Need help with "COUNT OFF"; option

  11 GR 2 11.2.0.3 under linux

  Hi everyone,.

  It's an honor to be with you guys.

  I have a big question here and I am unable to decide on a permanent solution.

  We have a primary database that is configured to have a logical expectation.

  The logic of the day before was not built by me. But I'm now support...

  So as the title suggests, there is NO primary index / unique + not null on a large number of tables in the database of emergency primary/logic. But the application logic guarantees uniqueness values rather than null.

  Here is where the problem starts.

  Guys request DO NOT want us to create an index on the primary database.

  According to my understanding, because the database lack of clues, the apply SQL must do a full table scan whenever it changes / remove data. It is a very expensive process and consumes a lot of time. This takes hours together to apply a minute with a value of newspapers on the logic of the eve... A huge lag is created during the hours and is not acceptable.

  So as I told you earlier, the guys request do not want an index on the tables not supported.

  They use the database pending logic exclusively for information purposes and it's like production for them...

  
  Let me give an overview...

  According to the document on the creation of the logic of the day before for 11.2 as below

  http://docs.Oracle.com/CD/E11882_01/server.112/e41134/create_ls.htm#SBYDB4730

  Step 1 to find tables without identifying unique logic in the primary database.

  Query the DBA_LOGSTDBY_NOT_UNIQUE view to display a list of tables SQL may not apply be able to uniquely identify. For example:

  SQL> SELECT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_NOT_UNIQUE

   2> WHERE (OWNER, TABLE_NAME) NOT IN 

  3> (SELECT DISTINCT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_UNSUPPORTED) 

  4> AND BAD_COLUMN = 'Y'; 

  The above query has 1040 tables in a particular schema. All the these have no index is not null primary / unique.

  
  Now according to the step 2 as below, we have an option to add a disabled RELY primary key constraint.

  Step 2 Add a disabled RELY primary key constraint.

  If your application provides the rows in a table are unique, you can create a primary key disabled RELY constraint on the table. This avoids the overhead of maintaining a primary key on the primary database.

  Can someone explain what this RELY constraint is disabled and how to function and help please?

  
  I have a few questions about the constraint to RELY.

  (1) change current plans of optimizer on primary for the execution price?

  (2) can help to boost the performance of SQL apply without creating index on the logical standby database?

  (3) it will change current plans of optimizer logical pending for the SQLs running?

  What are the options that I need to increase the performance and table scan complete engine AVOID SQL apply on the logic of the day before?

  Thanks a ton for reading my post.

  
  Kind regards

  Abhishek

  In fact, I've implemented a key primary rely disabled on primary and unique index on the logic of the previous day.

  The logic of Eve runs lightning fast now

• Primary database is RAC and physical intelligence is the single instance

  Hi all
  
  I use Oracle RAC 11.2.0.3 as primary database, we will begin to use the Oracle Data Guard.
  I am designing my infrastructure and planing to use single instance Oracle 11.2.0.3 my stand physical database.
  
  My question is it possible to have my sleep as single instance database while the primary is RAC?
  is it possible to build my Oracle database single instance ensures from the primary database to the RAC, RMAN backup?
  Are there restrictions (or all of the points to consider) as my primary database is CARS while the physics of Eve is the only Oracle instance?
  
  in the link below
  [http://docs.oracle.com/cd/B28359_01/server.111/b28294/concepts.htm#i1039416]
  It was mentioned that primary can be CARS or simple and even the day before, but my question is possible to have primary as CARS all on standby as single instance? or it should be like each other?
  

  The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters (RAC) database.
  Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle RAC database.

• LOG_ARCHIVE_DEST_2 parameter error and cannot start the primary database

  Hello
  I was getting errors in my RMAN backup script. I took a glance on the database settings. Looks like I made a mistake when I was in the LOG_ARCHIVE_DEST_2 setting in the standby database. Instead of putting on the eve I put it in the name of the primary instance. I also noticed that the LOG_ARCHIVE_DEST_2 setting has been changed in the primary database where I put it first. I guess he's changed when I changed the sleep setting. I have two questions:
  
  (1) can the parameter LOG_ARCHIVE_DEST_2 be changes for the correct setting now that I set it wrong. The reason why I ask is because when I tried to change by using the following ALTER SYSTEM command I got an error saying something about conflicting attributes. I guess it's because the name of the primary instance has been upgraded with the DB_UNIQUE_NAME instead of the name of the standby instance. If I could change the LOG_ARCHIVE_DEST_2 setting to sleep first then maybe I can change the primary to the correct setting? Please provide markets.
  
  ALTER SYSTEM SET LOG_ARCHIVE_DEST_2 ='SERVICE = < DB PRIMARY > ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = < PRIMARY_INSTANCE > '
  
  (2) the second question is you can start a database using a spfile? (I use ASM and Data Guard) I ask because while I was connected to the primary database I executed the following command:
  
  ALTER SYSTEM SET LOG_ARCHIVE_DEST_2 = 'SERVICE = < PRIMARY_INSTANCE > ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = < PRIMARY_INSTANCE >' scope = spfile;
  
  I then stop the database and try to start but it won't start because it says to conflicting attributes. I don't create a pfile from spfile file before you shut down the database. (I'm bad). How can I change the setting for the primary database to start over. (The PFILE file is different in ASM. There are sub + DATA but has only a single line indicating where is the location of the SPFILE) I need to run the following RMAN RESTORE CONTROLFILE FROM backup AUTOMATIC;
  
  Please help as it is a production environment that was supposed to be delivered only yesterday.
  
  Any help will be greatly appreciated!
  
  Thanks in advance.

• difference between the eve of the database and primary database

  can someone tell me the difference between the database and the database of relief in simple layman's language...
  
  Thanks in advance

  The primary database is the active production database.
  STANDBY database is a database backup (or read-only).
  Basically, the database pending is in power of the primary database (mechanism depends on the type of sleep) where users are connected to.

• Pending passage of the primary database to database

  Hi Experts,
  
  There is a database of oracle 10 g on a windows server and the database pending 1 * 0 g on another windows server *. The archivelogs in the primary database are generated on a network drive and they are applied on a regular basis of the primary database to the standby database, but now the primary database server broke down. If someone can tell me how to failover the database ensures the primary. I followed these steps but still Iam unable to move forward

  7 change the database for validation at the grade crossing;
  
  All records of the primary database in the backup catalog are applied with success, until no 6 but not 7 would give me an error indicating that the required media recovery. Can someone help me?
  
  Thanks in advance...

  HI srp.

  As u mentioned above you are primary database server crashed.

  Now, you want to switch to mode ensures primary school.

  Use the following commands to go to primary school

  1 startup nomount
  2. change the mounting base pending;
  3. recover standby database managed disconnect from the session.
  4 recover managed standby database finish skip standby logfile;
  5 change the database for validation at the grade crossing;
  6. immediate cessation
  7. starting

  Otherwise, you need to activate the standby database using the command sequence

  SQL > recover managed database finish pending;
  SQL > alter database activate standby database;
  SQL > stop & start.

  Kind regards
