• Effects of the opening of a primary database in resetlogs on the standby database

  Hi all

  Operating system: Solaris

  Can anyone throw some light below the explanation is given in case of recovery through the OPEN RESETLOGS Statement oracle documentation

  If the database pending...	Then...	Perform these steps...
  Not asked to redo data beyond the new resetlogs SCN (after the start of the new branch of data recovery)	Redo apply automatically takes the new branch of the roll forward.	No manual intervention is required. The MRP automatically resynchronizes the database pending with the new branch of data recovery.

  Just to give a concrete example, I did a test on one of my VM boxes. The database currently shows:

  SQL > select sequence #, the journal of v status $;

  SEQUENCE # STATUS

  ---------- ----------------

  34 ACTIVE

  CURRENT 35

  ACTIVE 33

  While on the eve, I stopped the redo apply so the standby status is:

  SQL > select sequence #, used from v$ archived_log;

  SEQUENCE # APPLIED

  ---------- ---------

  YES 30

  31 YES

  32 YES

  33 NO.

  34 NO.

  The database ensures in a few newspapers behind the primary.

  On the primary, I moved the journal a few sequences, close, the bootable media and restored and recovered 37 sequence:

  RMAN > run

  2 > {}

  3 > restore database;

  4 > up 37 sequence;

  5 > restore database;

  6 > alter database open resetlogs;

  {7 >}

  During the open resetlogs operation, I have to tail the log of alerts on the standby database and the following output shown:

  RFS [11]: identified the type of database such as 'physical' standby: customer is ARCH pid 17192

  So as you can see, the log shows the standby detects the resetlogs on the primary operation and the new branch of the roll forward and received the next archivelog with sequence 1.

  Audit on the eve, it shows the status following the archivelogs:

  SEQUENCE # APPLIED

  ---------- ---------

  33 NO.

  34 NO.

  35 NO.

  36 NO.

  37 NO.

  38 NO.

  2 NO.

  And after restart the managed recovery process, it now shows:

  SEQUENCE # APPLIED

  ---------- ---------

  31 YES

  YES 30

  YES 19

  YES 33

  34 YES

  35 YES

  YES 36

  37 NO.

  38 NO.

  1 YES

  2 YES

  Archivelogs with sequence 37 and 38 were not implemented because of the CAMILLE on the main sequence until (but not including!) 37 and then properly applied the next archivelogs of the new branch of the roll forward, with sequence 1 and 2.

• Archived not getting applied to the standby database.

  Hello
  
  I turned the parameter standby_file_management to manual and since I created 3 primary data file, but they are not applied to the standby database.
  I turned on the Auto setting and started the MRP process but still not able to apply archive.
  Version Oracle 10.2.0.5
  
  
  Please suggest,
  Amit Sharma

  Hello

  Your problem is that the MRP standby automatically when a data file is added on the primary database. The reason would be that the parameter STANDBY_FILE_MANAGEMENT is set to MANUAL on the standby database.

  Please refer to this http://shivanandarao-oracle.com/2012/04/02/managed-recovery-process-mrp-terminates-on-standby-database-upon-adding-datafile-on-the-primary-database/

• Backups on the physics of the standby database?

  I use dataguard and standby a physical database. How to assign backups on the physics of the standby database to reduce the load on the primary database.
  
  environment: windows
  
  Database version: 11.2.0.1.0
  
  
  What are the pro and cons on the allocation of jobs of RMAN backups for the physics of the standby database?

  Hello;

  The backup database is an identical copy of the primary database block.

  Therefore, you just save one of the two (you can choose to only save the day before, however, if you want to remove the load on the primary). But if you are uncomfortable with the primary backup, it is not necessary for the safeguarding of the day before. (Since you can recreate the primary backup before).

  The only important part, is that you use the RMAN catalog. Then only known RMAN, the two are identical and can use the same backup.

• create the standby database using backup to restore

  Hello

  I'm creating a database ensuring 11g using a manual process of restoring a backup, but nothing helped. I can restore same failed backup.

  Here are the steps that I followed (courtesy of ORACLE-BASE) BASE-ORACLE Data Guard physical standby Setup in Oracle Database 11 g Release 2 -

  I'm confused about these steps:

  Copy the files from the primary to the standby server.

  Copy Standby controlfile to all locations. 
  $ scp oracle@ol5-112-dga1:/tmp/db11g_stby.ctl /u01/app/oracle/oradata/DB11G/control01.ctl 
  $ cp /u01/app/oracle/oradata/DB11G/control01.ctl /u01/app/oracle/fast_recovery_area/DB11G/control02.ctl
  

  My question is, for the 2nd copy, I have to stop the primary db? given that control01.ctl is updated all the time?

  Then I have not used the previous day ctl (db11g_stbg.ctl) and copy it into /u01/app/oracle/fast_recovery_area/DB11G/control02.ctl instead?

  Your help is very appreciated.

• Question from beginner on the fusion of the Recrords in the Table

  This question is about question 10-b of merger on page 3-41, it says:
  (page 3-41 "Oracle Database 10g SQL Fund. II Vol.1")
  
  Merge the data into the EMP_DATA table that is created in the lab last in the data in the table emp_hist. assume
  EMP_DATA external table data corresponds to the EMP_HIST of table, update the email column
  table EMP_HIST to match the row in the EMP_DATA table. If a row in the EMP_DATA table is not
  match, to be inserted in the tables of EMP_HIST lines are considered as corresponding whenever his first and
  family name are the same.
  
  For me, this issue is built wrong. First of all in the last lab we have not been asked to create EMP_DATA. Secondly, EMP_DATA is empty.
  Thirdly, this question asks us to merge into the table EMP_HIST while EMP_DATA is empty.
  
  Table EMP_HIST currently copied data from the employees table. Structure EMP_HIST:
  
  FIRST NAME VARCHAR2 (20)
  LAST_NAME NOT NULL VARCHAR2 (25)
  EMAIL NOT NULL VARCHAR2 (45)
  
  EMP_DATA table is empty. I created it as follows:
  
  create or replace directory emp_dir
  like 'F:\emp_dir ';
  
  drop table emp_data;
  
  CREATE TABLE emp_data
  (first name VARCHAR2 (20))
  , last_name VARCHAR2 (20)
  , email VARCHAR2 (30)
  )
  EXTERNAL ORGANIZATION
  (
  TYPE oracle_loader
  Emp_dir default DIRECTORY
  ACCESS SETTINGS
  (
  RECORDS DELIMITED BY NEWLINE CHARACTERSET US7ASCII
  NOBADFILE
  NOLOGFILE
  FIELDS
  (first name POSITION (01:20) TANK)
  , last_name POSITION (22:41) TANK
  CHAR POSITION (43:72) by email)
  )
  LOCATION ('emp.dat'));
  
  Back to our question, I've done the merger as follows:
  
  merge into e emp_hist
  with the help of emp_data d
  on (e.first_name = d.first_name)
  When matched then
  game update
  Select = d.last_name,
  e.email = d.email
  When not matched then
  Insert values (d.first_name, d.last_name, d.email);
  
  I get this error:
  
  Error report:
  SQL error: ORA-29913: error in executing ODCIEXTTABLEOPEN legend
  ORA-29400: data cartridge error
  KUP-04040: file emp.dat in EMP_DIR not found

  29913 00000 - "error in the execution of %s legend".
  * Cause: The execution of the specified legend caused an error.
  * Action: Examine the error messages take appropriate measures.
  
  On the other hand, I said I'm going to try this:
  
  merge into emp_data d
  using e emp_hist
  on (d.first_name = e.first_name)
  When matched then
  game update
  d.last_name = select,
  d.email = e.email
  When not matched then
  Insert values (e.first_name, select, e.email);
  
  I get this error because the external table's final after its creation (no update, insert, delete authorized) as far as I know:
  
  Error report:
  SQL error: ORA-30657: operation not supported on external organized table
  30657.0000 - "operation not supported on external-organized table".
  * Cause: User attempted on the operation on an external table which is
  not supported.
  * Action: Don't do that!
  
  **********************************
  
  I don't know what to do. I did my best, please help.

  What happens if I want to import large data set in the external table?

  Hmm, external table is just a definition on how you want to watch a file as a table in the database. Think of it as a tool to import data.

  1. first of all, have a ready file (with data).

  2. create an external table using the format of the file.

  3. now you should be able to see the data when you do this. Select * from my_external_table.

  4. now, create an ordinary table where you want the data to insert permanently.

  5 insert into permanent_table select * from my_external_table.

  I hope this helps.

• Need help on Physics of the standby database

• Upgrade to 11.2.0.4 with the physics of the standby database

  Dear gurus,

  
  We have the obligation to upgrade databases 11.2.0.1 existing 11.2.0.4 and 11.2.0.2 to 11.2.0.4 running on AIX boxes. We have physical databases of Eve configured for these databases of different version.

  During the preparation of the documentation for upgrade, we observed that FORCE_LOGGING is disabled for the production databases and observed, there are objects along 350 + with journaling = No. and logging = NULL and patterns are SYS, SYSMAN, APEX_030200, OLAPSYS, XDB, SYSTEM, OIMDBUSER, MDSYS, EXFSYS, WMSYS, ORDDATA, PERFSTAT.

  My query:

  I can still proceed with the upgrade still under the document indicated for "upgrading a database with a physical Standby database in place" without you connect the data dictionary objects will be not be updated pending database.

  Can you please let me know your suggestions on this please?

• GoldenGate to replicate physical of the standby database

  Friends,

  I don't have an answer instead of data guard

  Could we use oracle Portal gold to replicate a physical custody ensures data in a new logical basis?

  Or we need to replicate keeps the primary database data in a new logical basis?

  Thank you

  newdba

  Use the extract parameter TRANLOGOPTIONS with the ARCHIVEDLOGONLY option. This

  force option extracts for ALO mode against a primary or logical standby

  database, as determined by the PRIMARY or STANDBY LOGIC value in the db_role

  column in the view v$ database. The default is to read newspapers online.

  TRANLOGOPTIONS with ARCHIVEDLOGONLY is not necessary if you use the ALO mode against a

  standby database physical, as determined by the PHYSICAL INTELLIGENCE value to the

  db_role column of v database $. Extract works automatically in ALO mode if it

  detects that the database is a physical standby.
