• ORA-01830 during an attempt of incomplete recovery

  Hi guys,.
  
  I practice the incomplete recovery but my RMAN script fails with the following error:
  ORA-01830: date format picture ends before converting all of the input string
  
  Here's the RMAN script
  
  RUN
  {
  May 7, 2010 until 05:00 ";
  restore the database;
  recover the database;
  ALTER database open resetlogs;
  }
  
  My NLS_DATE_FORMAT has the value
  * # env | grep-i nls *.
  * # NLS_DATE_FORMAT = HH24:MI:SS * MON-DD-YYYY
  
  Linux x 86, Oracle 10.2.0.4

  In your case, case issues (my output is in windows, but should be the same on linux)

  SQL> alter session set nls_date_format='DD-MON-YYYY HH24:MI:SS';  -- sqlplus can handle uppercase
  
  Session altered.
  
  SQL> select sysdate from dual;

  Now let's see what happens when I put the NLS_DATE_FORMAT correctly:

  C:\Documents and Settings\User>set nls_date_format=DD-MON-YYYY hh24:mi:ss
  
  C:\Documents and Settings\User>rman target /

  4> }
  
  executing command: SET until clause
  using target database control file instead of recovery catalog
  

  Now, usually when I write RMAN scripts I'll put the nls_date_format there it will always be good for the rman session:

  run {
  set until time "to_date('07-MAY-2010 05:00:00','dd-mm-yyyy hh24:mi:ss')";
  }
  

• difference between complete and incomplete recovery

  someone can explain the difference between incomplete recovery and full

  Hello

  I think everyone had given enough information the subject.
  Always add some info might be useful: -.

  Complete the recovery: -.

  Basically completely recovered, as the word says full, why must the files (I mean that Backup should persist)
  Backups of data files, logs needed archiving, online redo logs and the controlfile are available.
  The DB can undergo or experience of damage with losing them any information. This case led to a complete recovery.

  The usual process of recovery will be (user managed)

  Make files of data performed in offline mode
  Restore data files
  Recover data files
  Make data files online

  Complete healing is possible, while the database is OPEN and until or unless that important storage spaces get made that SYSTEM or UNDO tablespaces.

  Incomplete recovery: -.

  That the specified name to lose data on purpose, it is said when a complete recovery is impossible or you want to lose some information which has been recorded by mistake or due to corruption of the files. This leads to the incomplete recovery
  Some time its effects in reason lost some files as file control and current control file does not know the current state of the DB. These cases causes too incomplete recovery.

  Incomplete recovery steps:

  Mound the DB
  Restore files
  Recover the database (up to time, cancel or change the number or number of SNA)
  Finally open the DB with newspapers to reset

  Please keep in mind that RESETLOGS Initializes the redo online files, and this is a new incarnation of the database.

  You can also use the RMAN to achieve things.

• incomplete recovery of a data file.

  I'm performing incomplete recovery of a data file that uses the following scenario.
  SQL > select * v log$;
  shows current journal seq is 10;
  
  I perform dml as follows:
  SQL > update hr.emp set salary = 1000;
  SQL > commit;
  
  Now, I've deleted log archiving with sequence # 9 alongwith users.dbf datafile.
  Now to perform an incomplete recovery of the datafile, users.dbf. I followed the following steps.
  RMAN > the judgment;
  RMAN > bootable media.
  RMAN > run
  {
  until the sequence 9;
  restore data file 4;
  recover datafile 4;
  }
  RMAN > alter database open;
  Now, when I ask about hr. EMP, it shows the updated lines, i.e., salary column has been updated with 1000;
  I want to know that after the incomplete rcovrry until the seq, what other newspapers is applied. My example shows that this newspaper seq 10 has also been applied. Pls help me to improve my understanding.
  I can't understand the reason to get updated when the incomplete recovery lines.

  Hello.

  You cannot perform incomplete recovery of a single data file. After recovery, before opening the database, all SNA must be synchronized between controlfiles, redo logs and data files. A single data file must be restored and recovered to the last SCN for the database to open. If you want / need to do incomplete recovery, always restore ALL data files, recover their until the desired point in time and then open the database with resetlogs synchronize all data with controlfiles and redo logs files.

  In your case, you have made a complete recovery of the data file. Very probably data repeat still available in the online redo logs were used to recover the data at the last CSS file (since you said that you have removed the archiving log - which, incidentally, makes your online backup no need for a full recovery, after the redo logs switch line and crushes with sequence #9 redo log and beyond).

  When experimented with incomplete recovery, until the RCS or at least up to the time, it allows you to specify the point in time recovery with much more accurately and without guessing, what happened in whatever sequence of journal. You must manually remove the files of data or archivelog files before playing with incomplete/complete recovery. In fact, it is a good practice not to delete the database of linked files: o)

• incomplete recovery until error

  I want to perform incomplete recovery with RMAN using up to that time, I performed the following tasks
  
  stop immediately;
  bootable media;
  ALTER session set nls_date_format ='YYYY-MM - DD:HH24:MI:SS';
  
  RMAN target sys/sys@alvis
  
  Run {}
  until the time ='2011 - 02 - 10:15:25:00';
  restore the database;
  recover the database;
  ALTER database open resetlogs;
  }
  
  
  but it shows the following error
  
  RMAN-03002: failure of the command set to 10/02/2011 16:41:31
  ORA-01861: literal does not match the format string
  
  
  Wat could be the problem?
  
  
  Thanks in advance

  You set your NLS_DATE_FORMAT in a database session, however, your RMAN connection is for another session.

  Try setting NLS_DATE_FORMAT as an environment variable in your OS BEFORE connecting to RMAN command-line.

  Something like:

  C:\>SET NLS_DATE_FORMAT=YYYY-MM-DD:HH24:MI:SS
  C:\>RMAN sys/sys@alvis
  

  or

  $ NLS_DATE_FORMAT=YYYY-MM-DD:HH24:MI:SS
  $ export NLS_DATE_FORMAT
  $ RMAN sys/sys@alvis
  

• RMAN incomplete recovery

  Jin
  I use oracle10g (10.2.0.4.0) in windows service pack 2 32-bit. with RMAN, I took a backup of a tablespace. Then, I created a table and the database is closed. Off, I deleted the file data in this table. Now I started the database in the editing phase, started the RMAN. I restored the tablespace by RMAN and then I got to a point where I did not create the table. But the RMAN performs a complete recovery. When I check the table there is always. How is it possible? can someone help me please... I am totally confused.
  
  Here are the commands I used in the above scenario
  
  RMAN > BACKUP TABLESPACE USERS (BACKUP 13:00 HRS)
  
  
  SQL > CREATE TABLE TEST AS SELECT * FROM EMPLOYEES; (CREATED AT 17:00 HRS)
  SQL > IMMEDIATE SHU
  
  physically remove the data from the users table space file.
  
  SQL > STARTUP MOUNT
  
  RMAN > CONNECT TARGET SYS/password
  
  RMAN > RESTORE TABLESPACE USERS
  
  RMAN >RECOVER DATAFILE 4 until time ' to_date ('2010-11-23 16:00 ',' ' YYYY-MM-DD HH24:MI:SS) "
  
  SQL > ALTER DATABASE OPEN RESETLOGS (DISPLAYS AN ERROR THAT RESETLOG CAN SE DO AFTER INCOMPLETE RECOVERY)
  
  SQL > ALTER DATABASE OPEN
  
  SQL > SELECT * FROM TEST (THE TABLE EXISTS)
  
  
  Please tell me what is wrong in the above scenario? I use wrong queries?
  
  
  Thanks in advance

  You cannot recover a Tablespace (or Datafile) to a point in time that is not consistent with the rest of the database, unless you use an auxiliary Instance. TSPITR (TablespacePointInTimeRecovery) uses an Auxiilary Instance where SYSTEM, UNDO and the required storage space are recovered to the point passed in time without affecting the current instance of the current database. The tablespace can then transported the auxiliary to the active database instance - you can have RMAN automatically do this but, personally, I would manually.

• Incomplete recovery of 17 HP envy touchsmart

  I have a laptop HP Envy Touchsmart product model E1P14AV 17 t-j100 number 17.

  I'm trying to restore to the factory via a USB port, but get incomplete restoration. I tried all the methods of the HP recovery method and all three gave the same answer. It runs through everything and reload the software but gives this answer. If I click on try again it tells me to insert the recovery media.

  Try changing the date in the BIOS to 01/01/2012. Save & Exit. Boot from recovery and to run the process-, but on the first reboot, it initiates enter the BIOS to ensure the update is still. If so let recovery resume - if not change again, then restart.

• Incomplete recovery, cannot get further than to insert media

  I tried to perorm a cooling system on my windows 8 hp portable m7-j020dx. a full backup of the system was executed just before the update just in case.  After the update the laptop rebooted one last time and a screen popped up indicating implete restoration.

  The list of errors are as follows

  [6:58:36.74] ChkErrBB.CMD: detect an error in the PININST_BBV.

  [6:58:36.74] ChkErrBB.CMD: check c:\system.sav\Logs\BurnBootWarn.log

  [6:58:36.77] --------------------------------------------------

  [6:58:36.77] critical error condition has been detected to BBV1...

  First of all I do not have to do a system restore just a system refresh.  Second on the pop-up screen, he says the restoration has not ended.  Please select one of the following buttons:

  Save the details of the journal try again

  I saved the newspaper, I looked at the details, but, when I click on start a new screen appears that says insert media recovery. Unfortunately, I can't get past this point. I can hear the CD drive spin upward and try to read CD inside, but nothing else.

  I didn't remove the disc 6 but, it is not reading. I opened the CD player and I tried the 1st disk, still nothing happens. I then tried the rest of the 2nd, 3rd, 4th, 5th, 6th CD. Then, I tried to boot up the laptop hard and again the same screen came, and the same problem occurs.

  I also went into the bios and went through every possible system check and they all came back past. (notice, the only thing I did the laptop hardware wise was having a 840 840 samsung series series 250GB SSD professionally installed and had information on the original HDD migrated on the SSD using the supplied migration of samsung software.) Any help would be greatly appreciated.

  I tried to insert the old hard drive. Goes on for some strange reason (and that includes most of the computers laptops hp not only the m7-j020dx) in order to solve the problem. You must restart the computer quickly press ESC to enter the bios. Once in the bios, press f5 to reset to the factory settings. Press f10 to save and exit. After that, the recovery of HARD drive works perfectly.

• Impdp problem with disconnection of Oracle (without recovery)

  Hi all
  
  I am trying to import a data dump generated from an Oracle Enterprise Manager 10.2.0.4.0 on a server unix with the following command:
  expdp mc/XXX DIRECTORY = DUMPFILE EXPORT_DIR = SLTN-MCEXPORT-2010-07 - 22.dmp PATTERNS = MC LOGFILE = SLTN-MCEXPORT-2010-07 - 22.log
  
  I want to import into oracle XE 10 g (10.2.0.1.0) on a windows server. That's why I do the following:
  
  Impdp mc/xxx DIRECTORY = DUMPFILE EXPORT_DIR = SLTN-MCEXPORT-2010-07 - 22.dmp PATTERNS = MC LOGFILE = SLTN-MCIMPORT-2010-07 - 22.log
  
  I had to manually create TABLESPACE MC_DATA: 'MC_DATA' of CREATE TABLESPACE DATAFILE 'D:\OracleHisRuns\Dumps\SLTN-MCEXPORT-2010-07-22.dmp ';
  
  Then a table fails MC. CURVEPOINTS
  
  And finally we are disconnected from Oracle
  
  The determined type SCHEMA_EXPORT/TABLE/INDEX/INDEX processing
  UDI-00008 operation error 3113 and 3114 error.
  
  and I can't get back. I again install Oracle XE.
  
  Anyone know why this is happening? Is it a memory problem? Or is there a problem when the user, the tablespace is created next to me?
  Maybe the export and import between these two Oracle database versions are not compatible?
  
  Any help would be greatly appreciated.
  
  Many thanks in advance,
  Thomas

  Hello
  I think you're confusing the creation of storage with the expdp dumpfile. You tried to add the dumpfile to the database as a data file, and then it was corrupted.

  What you need to do is add a new space of tables with a brand new file - nothing to do with the dumpfile.

  And then perform the import with the dumpfile - you will probably need to this regenerate your source system.

  See you soon,.

• RMAN backup - incomplete recovery

  Hi guys,.
  
  just a test scenario.
  
  For example, I have a daily rman full backup at 20:00 yesterday. the database is in archiveloj... However we do not backup the archivelogs.
  
  This morning at 10:00, all databases, controlfile, redologs, archivelogs files are deleted from the system accidentally.
  
  
  the database can still be restore?
  
  1. create the controlfile to trace
  2. restoring the database
  3. restore database until cancel (it will be prompt will be the next newspaper which is not available)
  4. alter database open resetlogs
  
  open resetlogs will work without even a log available to apply to the rman backup archiving?
  
  Thank you

  The question is: "what is the definition of a FULL BACKUP?"

  What you have is a database backup that did not include the ArchiveLogs.
  You cannot recover the database with only a database backup unless the database backup was in State of MOUNT-no is not OPEN.

  A "backup of the closed base" is a FULL database backup.
  A "hot Database backup' is not COMPLETE unless ArchiveLogs are included.
  The command 'BACKUP of DATA PLUS ARCHIVELOG' RMAN; could meet the requirement of a full backup (although it does not include the ORACLE_HOME, EM/GridConsole tnsnames.ora, listener.ora files, etc).

  Day 1, day 2, day 3... consist of hours for the respective activity.
  
  
  Please guide me how to go about... I tried to create views. What will be the best way to do it.

  select activity_name,
         sum(decode(effort_date,:day1,hours,0)) day1,
         sum(decode(effort_date,:day1+1,hours,0)) day2,
         sum(decode(effort_date,:day1+2,hours,0)) day3,
         sum(decode(effort_date,:day1+3,hours,0)) day4,
         sum(decode(effort_date,:day1+4,hours,0)) day5,
         sum(decode(effort_date,:day1+5,hours,0)) day6,
         sum(decode(effort_date,:day1+6,hours,0)) day7
  from Activity a, Activity_details d, Effortentry e
  where a.activity_id=d.activity_id
  and d.effort_id = e.effort_id
  and effort_date >= :day1
  and effort_date < :day1+7
  group by activity_name
  

  As you can see you need to pass only a single parameter: day1.

• Incomplete data file recovery

  Hello
  
  I use oracle database 10g (10.2.0.10) in RHEL5. I want to make a point in time recovery a backup data file. Through RMAN, I published the following command
  
  RMAN > run {}
  2 > sql ' alter session set nls_date_format = "dd-mon-yyyy hh24:mi:ss";
  3 > set until that time August 21, 2011 13:04 ';
  4 > restore datafile 4;
  5 > recover datafile 4;
  6 > alter database open resetlogs ;}
  
  But RMAN made a full recovery. Yet once again, I deleted the data file and restore the backup data file. Now, I wrote the following at the SQL prompt
  
  SQL > alter session set nls_date_format = 'dd-mon-yyyy hh24:mi:ss ";
  Modified session.
  SQL > recover datafile ' / u01/app/oracle/oradata/ORATESTDB/datafile/o1_mf_users_751h7fmh_.dbf' until August 21, 2011 13:04 ';
  ORA-00274: illegal until recovery option
  
  It displays the above error. But I am able to perform incomplete recovery of the complete database using RMAN same as above.
  
  Done datafile point-in-time recovery is not possible? or is there something wrong in my approach?
  
  Kind regards

  A data file can be recovered to a point in time which is incosistent with the rest of the database.
  (why? Data integrity! A table with several extensions that can cover several data files. You can't have some scopes with data from 12:05 and other extensions into another file of data retrieved using data from 10:05! Even if it's a single datafile tablespace, you will violate referential integrity (whether or not they are applied) If, say, the SALES table has entries until 12:05, but the SALES_LINES table has entries until 10:05!)

  You can make a Tablespace recovery time by using an auxiliary Instance and then copy the tablespace back. You must maintain integrity.

• Recovery in Oracle 10g XE problem

  Hello
  
  I made a backup of database earlier. I dropped a table after that and tried to recover the database.
  It gives the following errors:
  SQL > recover database until cancel using backup controlfile;
  ORA-00283: cool cancelled due to errors
  ORA-01110: data file 6: ' / usr/lib/oracle/xe/oradata/XE/andromeda1.dbf'

  ALTER database open resetlogs

  I deleted the andromeda1.dbf Advisor manually.please.
  
  Thank you

  Sorry for the delay in replying I was kinda busy :)
  You should try to identify what tablespace file belongs, for example using the script below:

    1  select tablespace_name, file_name
    2* from dba_data_files
  SQL> /
  
  TABLESPACE_NAME                          FILE_NAME
  ---------------------------------------- ---------------------------------------
  SYSTEM                                   C:\APP\MOB\ORADATA\ORCL\SYSTEM01.DBF
  SYSAUX                                   C:\APP\MOB\ORADATA\ORCL\SYSAUX01.DBF
  UNDOTBS1                                 C:\APP\MOB\ORADATA\ORCL\UNDOTBS01.DBF
  USERS                                    C:\APP\MOB\ORADATA\ORCL\USERS01.DBF
  

  You should file a tablespace to which this file belongs

  drop tablesapce tablespaceName including contents;
  

  The last thing to do is to remove the file from the file system

  rm -f /path_to_your_file
