• Diffrence between the tablespace is ONLINE and READ WRITE?

  Hi all

  I'm very confused on the tablespace is ONLINE and READ WRITE?

  Some say that if the tablespace is online, this means that its READ WRITE and when its offline then its READ-only.

  So, what is the difference between them:

  ALTER TABLESPACE offline tablespacename; -> done mean READ only now?

  ALTER TABLESPACE tablespacename online; -> is it means its READ WRITE now?

  If Yes, then what is the use of the following command if above 2 commands? :

  ALTER TABLESPACE tablespacename [READ ONLY |] READING WRITING];

  Kind regards

  Confused Ritu

  In addition, when the tablespace is offline, objects belonging to those who are not available for use to users. You wouldn't be able to query for objects in a tablespace offline.

  When the tablespace is read only - no write operation cannot be performed i.e. etc. INSERT/UPDATE/DEL. Oracle says that read-only tablespaces provides a way to protect the historical data so that users cannot modify it. You can drop objects, such as tables or indexes, to a tablespace read-only, but you can't create or modify objects in a tablespace read only

  In order to bring a tablespace OFFLINE to ONLINE - so that it is available to users, you must "ALTER TABLESPACE online tablespacename" command. A tablespace online can be READ ONLY or READ WRITE mode.

• ALTER table move online in an encrypted tablespace

  Hello

  Our DBA want to put all our data in encrypted storage.

  Once they create encrypted tablespaces, we will have to do «alter table move online...» "orders for encrypted storage space around the tables.

  Has anyone here done already?   Keeps the table moved really 'on-line' (available at query/insert/update) during the move?  Or will we have to wait some time stop/downtime while the tables are moved?
  What about the tables with long or CRAFT?

  Thank you!

  KSandberg and to add to the recall of John that only ITO tables can be moved online, if the table needs to be moved offline the indexes would be invalid until rebuilt.  If the table is an IOT I suggest you rebuild the index online after the move because even if the indexes are always used the logical ROWID is more pointing to the correct location and access of the index will be less effective that will you rebuild the index.

  The dbms_redefinition package could be an alternative solution if you need to move the tables no - ITO online.

• ALTER TABLESPACE BEGIN BACKUP MODE

  Hi all
  When we issue alter tablespace begin backup command then freezes the data file headers and all modified blocks will be written to streams and when we issue end backup command then the database will write the blocks changed to data files by accessing files redo.
  my doubt is suppose archiver process archive redo files and all redo files are overwritten. now how the database will write the changed blocks to restore and database dealing with this task.
  
  TIA

  "Hot backup" is obsolete with 10g or more recent technology as Rman covers this much better.
  Please switch to RMAN at your early convenience.

  Also, as the database must be in archivelog backup online, it is not a problem, that the online redo log files are overwritten, like recovery will use two online redolog files and archived.
  Your question doesn't make sense to me.
  Redo are written in files LGWR, ARCH Archive files. Changes are written to the database by DBWR. All who are independent processes, and the changes are written to redo front to be written to the database.

• alter tablespace offline...

  Hello
  
  http://docs.Oracle.com/CD/E11882_01/server.112/e25494/tspaces005.htm
  
  just a quick question,
  

  alter tablespace....offline temporary

  A tablespace can be taken offline temporarily, even if there are error conditions for one or more files in the storage space. When you specify TEMPORARY offline, the database supports offline data files that are not already in offline mode, the control points as she does.
  If no file is offline, but you use the temporary clause, media recovery is not required to bring to the online storage space. However, if one or more files from the storage space are offline due to clerical errors, and you are taking the tablespace offline temporarily, the tablespace requires recovery before you can bring it online.
  
  Based on the explanation above, done means that these datafile (with the error condition) code with the storage space you want to use offline will not in offline mode.
  Oracle will be only offline these 'good' datafile associate with storage space?
  
  My confusiong early when he mentions:

  if one or more files of the tablespace are offline because of write errors,

  which make me feel that even in the midst of erros, all storage data files will be always taken offline.
  
  The documents also mention:
  

  Specify TEMPORARY only when you cannot take the tablespace offline normally. In this case, only the files taken offline because of errors need to be recovered before the tablespace can be brought online. Specify IMMEDIATE only after trying both the normal and temporary settings.

  In this case, based on my current knowledge, I mention since all data files are taken offline in the middle of the condition of erros, we just need to recover those files that have the condition of error on them. ???

  Well, Yes, but it's because the files of data with errors will already be ordering offline offline will not be offline them.
  >
  that means the code of these datafile (with the error condition) with the tablespace you want to use offline will not be in offline mode
  >
  No - the doc says that data files wilth errors have been offline. And after ordering TEMPORARY if you try to put the storage space online, it will fail because it will try to put offline the with online also return errors.

  That's why the doc has this cautionary
  >
  Caution:

  If you take a tablespace offline, use the NORMAL clause (default) if possible. This setting ensures that the tablespace requires not coming online restore, even if after incomplete recovery, you reset the sequence of redo logs using an ALTER DATABASE OPEN RESETLOGS.
  >
  You should check the status of all data files before you use CONNECTION TEMPORARY offline, or if a data file is already offlilne because of a clerical error, you will find that what you thought was temporary will avoid you to bring online storage space unless you do a recovery.

• Missing ALTER TABLESPACE syntax... STRATEGY TO ADD DEFAULT ILM

  Hi all

  I'm checking the syntax of the statement:

  ALTER TABLESPACE tbs1

  STRATEGY TO ADD DEFAULT ILM

  STORE COMPRESS ADVANCED SEGMENT LINE AFTER 30 DAYS OF ACCESS LOW;

  The statement of work, but I found this syntax in the SQL (version 12.1) reference.   The song 'ILM add POLICY' after the 'DEFAULT' keyword is not documented.

  Did I miss something or Iit s a lack of documentation?

  Thank you

  Best regards

  Angelo Della Penna

  John,

  The OP post "alter TABLESPACE.

  (The DEFAULT clause for ALTER TABLESPACE for the TABLESPACE points CREATE documenttion).

  There is no clause of ILM for default for CREATE TABLESPACE.

  https://docs.Oracle.com/database/121/SQLRF/statements_7003.htm

  Therefore, it is undocumented (or a bug in the documentation)

• How to change the 'Drive' for the BSO cubes (just like we do using "alter tablespace" for ASO cubes) using MAXL etc.?

  Hello team,

  I'm trying to make a backup copy of the cube by using the copy commands, BSO

  but after copy, I need to change the drive letter (for the data and indexes of the files) using MAXLs.

  I am able to do for cubes ASO using "Alter tablespace" i.e. for example, change "D:\" car ' to 'E:\. "for the tablespace files.

  I need to do the same for the BSO cubes? any idea?

  Kind regards

  Amit

  Don't forget while you can also change the drive it can't displace data. You would have to export the data, delete the database, change the disks, and then reload.

  For the actual command of MaxL watch the MaxL Alter Database command. You can add, dorp or set volumes of disk for ind and pag files

• How to Setup Data Guard with alter tablespace... begin backup approach

  Hello!
  
  I am writing this compilation of documents in a guard daata establishing in 10g. I was in charge to present different approaches in implementing on Rhel 5.
  
  I came across 3 procedures (which is to duplicate a database with RMAN, then configure it to a Data Guard feature). I read a process using (let's this is what the article said, but procedure was presented):
  
  alter tablespace... .begin backup;
  alter tablespace... .end backup;
  
  then copy the generated files and configure it to the data protection feature.
  
  Someone help it with that? Is there like a blogsite or steps I can take for this scenario?

  Hello;

  The best I found was: (and its same 10 Oracle! and not RMAN.)

  http://sites.Google.com/site/catchdba/physical-standby-database-using-HOTBackup

  There, an old link here on this topic:

  DataGuard configuration using hot backup files

  Hard to find much on this topic as "Hot Backup" almost always comes to RMAN.

  This collection of notes can also help:

  DataGuard knowledge browser Product Page [ID 267955.1]

  And the "Formidable" Powerpoint:

  www.dbspecialists.com/files/presentations/standbydb.ppt

  Seems that this method is dead somewhere between Oracle 8 and Oracle 9

• Alter tablespace name wrong when creating data file

  Hello
  
  While creating a data file, I used alter tablespace name wrong.
  For example,.
  I used:
  ALTER TABLESPACE ADD datafile APPS_TS_SEED ' / d01/oracle/stkmnfun/db/apps_st/data/a_txn_data05.dbf' size 1024M;
  
  Correct one:
  ALTER TABLESPACE ADD datafile APPS_TS_TX_DATA ' / d01/oracle/stkmnfun/db/apps_st/data/a_txn_data05.dbf' size 1024M;
  
  I have created a more a_txn_data06 with the correct STORAGE space...
  But, did anyone know how this can be corrected?
  
  
  Thanks in advance,

  As long as it has not at all affected in this data file, you can deposit with

• is it OK to alter tablespace temp SYS of the running production database

  Dear,
  
  is it OK to alter tablespace temp of the user SYS of the running production database
  
  Business database version 10.2.0.5
  single instance on AIX
  
  We have two temp tablespace temp and temp2
  
  I'm trying to rebuild the index by using sys connection but its not working, cannot extend the temp tablepspace
  
  then I checked this system a default temp tablespace is of a size of 2 GB
  
  on the other hand, all other schemas has (including the owner of the index) have the temp of larger size.
  
  
  He suggests to change the tablespace temp of SYS.

  Ok. Then the answer is Yes, change the SYS temp tablespace should not be a problem. If you use SYS to reconstructions of index maintenance is another story. In any case, Yes, change the tablespace temp should not be a problem. Other sessions of this user would continue using the old tablespace until their completed transaction. New transactions will begin using the newly designated temp tablespace.

  Hope that helps,

• Question about ALTER TABLESPACE add datafile on/slide

  Good afternoon
  
  As an exercise, I created a STORETABS tablespace and added a data file using the command:
  

  SQL> alter tablespace storetabs add datafile 'e:/storetabs3.dbf' size 50M;

  This successful step. A new file was created at the root of e: as expected.
  
  Following this command, I have published:
  

  SQL> alter tablespace storetabs drop datafile 'e:/storetabs3.dbf';
  
  Tablespace altered.

  The command succeeded. However, the file * ' e:/storetabs3.dbf' * has not been deleted. After re-reading the documentation found at http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_3002.htm, I feel that deleting the operating system file itself is something that must still be done manually.
  
  Question: Am I right that there is no option to cause 'alter tablespace < tablespace > drop datafile < datafilename >' remove it the o/s file? In other words, should the o/s file always be deleted manually as a separate step?
  
  Thank you for your help,
  
  John.

  John,

  Don't know what part of the documentation page you are referring to but on the same page to the following location
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3002.htm#sthref5437,
  He clearly staes

  Specify DROP to drop from the tablespace an empty datafile or tempfile specified by filename or file_number.
  This clause causes the datafile or tempfile to be removed from the data dictionary and deleted from the operating system.
  The database must be open at the time this clause is specified
  

• ALTER Index Rebuild online

  My database is out 10 gr 2. Sometimes, I pass command ALTER INDEX < index name > REBUILD online on the indexes that are 500 MB in size. It takes about ten minutes to run the command. The database alert log shows no activity for the first six minutes, and DML is allowed on the associated table. At about minute seven journal alerts shows the first of a series of five online redo logs switches. They are each 100 MB.
  
  During the time that online redo logs, DML execution sessions cannot fill. When the new version of the index was created again online records switching station, the original copy of the index disappears, the ALTER INDEX command ends, and blocking for DML ceases.
  
  I read that the DML statements are not affected by executing ALTER INDEX REBUILD online, but experience shows that the blocking of the above sessions. Can someone explain to me what is happening in the different stages of the index rebuild? Is there something I can do to eliminate the blocking of the DML statements during the period when redo online record switch?
  
  Thank you
  Bill
