• Alter system switch logfile

  Hi all

  9i

  RHEL5

  We make the standby database as our report server. It comes to unload part of the Production workload to improve performance.

  To get the latest data, or before you run reports on the standby server, I'll first > alter system switch logfile;

  So that the backup database will be updated the last transactions to date.

  How often should I run the command? Is this enough to run it only once? or I'll run it n times according to the number of newspapers of recovery?

  Thank you very much.

  JC

  In 9i to run queries on the standby database, you must open the database in read-only mode standby. In this case there is therefore no question of switching logfile or so. Before opening the database in standby mode ReadOnly, you make sure that all the archiving of primary logs are applied to the standby database in managed recovery mode. Once this Eve is open for requests.

  I suggest you read below. It erases the concepts and is specific for 9i

• alter system switch logfile crashes

  Hi Experts,

  Please help me determine the above error.

  Recently, I was told to take one of our EBS environment in archivelog mode. While doing this activity, I coped 'ORA-16014.

  The steps that I follow are listed below:

  SQL > alter system set log_archive_dest_1 = ' location = / mnt/DEVarchive/trcdev ' scope = spfile;

  Modified system.

  SQL > alter system set log_archive_format='TRCDEV_%s_%t_%r.arc' scope = spfile;

  After reading the newspaper to alert carefully, it is clear that it is not able to archive the logs and archiving is hung.
  

  The reason could be my destination Archive got filled, but in my case, my destination archive has a free space of about 24 G.

  
  

  Please tell me how to troubleshoot further, a quick response will be highly appreciated.

  
  

  -Thank you
  

  @John

  I checked log_archive_dest_2 and it is set to null. And I think it would be better if I leave it in its default state.

  @Mustafa

  Db_recovery_file_dest is also set to null.

  Further, I disabled the archivelog mode and erase all the settings that I did for archiving logs (parameter as log_archive_dest_1 log_archive_format).

  I have another session close immediately and started the database in editing mode. After that, I activated all the setting again and activated the archivelog mode for my database.

  SQL > alter database open;

  Did bounce my DB once again, and then manually change logfiles 2 - 3 times and BOOM everything seems to work fine now. No more no hung sessions and archives are generated too.

  A big thanks to everyone in this thread.

• Query on ALTER SYSTEM SET

  
  Hello

  I was under the impression that

  "PFILE has limitation to change settings for initialization of dynamically. If any initialization parameter must be changed, we can edit the pfile parameter changes take effect with the next restart of the system

  To work around this limitation, Oracle has created the concept of the SPFILE initialization parameter can be changed dynamically using ALTER SYSTEM SET statement. »

  But, today, I started my test using PFILE database and run the following command to change the setting of the memory_target from 300 to 290 M.

  ALTER SYSTEM SET memory_target = 290 M;

  And to my surprise, this statement executed correctly without errors and memory_target parameter has been set to the new value (of course, in memory).

  Isn't it change the init dynamically using PFILE itself?

  Please clarify my doubt and correct my understanding.

  Kind regards

  You have a bad mixing on the genesis of the SPFILE. Yes, it is a binary file and all this but remember, isn't the SPFILE which makes a dynamic parameter or a PFILE that makes static, but it is the nature of the setting itself which allows to happen. Yes, the difference in the PFILE and SPFILE parameter would be obvious when you change a dynamic parameter, and would give a rebound to the db. Since the PFILE file has not been updated (it's a text file must be updated manually), with the next restart, the setting would take the same value as it has in the PFILE file. But with the SPFILE, depending on what you have set in SCOPE, the parameter should behave accordingly.

• When ALTER SYSTEM ARCHIVE LOG happens implicitly...

  Hello
  
  When you scan the v$ archived_log SIDE primary SCHOOL, I saw below output
  
  NAME OF CREATOR REGISTR SEQUENCE # FAL
  -------------------------- ------- ------------ ----------------- ---
  /U05/prod/archivelogs/ARC_816992406_1_22885.dbf ARCH ARCH 22885 No.
  /U05/prod/archivelogs/ARC_816992406_1_22886.dbf FGRD FGRD 22886 No.
  
  
  Then I went to the alert log file and search for the sequence #, I found that
  
  When the newspaper switch happens through * ALTER SYSTEM ARCHIVE LOG *, then this sequence archive log CREATOR and REGISTRAR will be FGRD.
  What command of newspaper happens automatically (90% complete log file), then this sequence archive log CREATOR and REGISTRAR will be ARCH.
  
  
  If * ALTER SYSTEM ARCHIVE LOG * happens synchronously means control will not return to the process unless and until the underlying log file has been
  archived completely, so the CREATOR and the REGISTRAR is FGRD.
  
  My question is, under what circumstances * ALTER SYSTEM ARCHIVE LOG * happen implicitly.

  I agree with you.

  The environment that I take abt is DATAGUARD Enviornment.

  I have not published ALTER SYSTEM ARCHIVE LOG CURRENT of any session (foreground process) of the primary DB.
  But I can still see ALTER SYSTEM ARCHIVE LOG in the log to alter.

  When you call the command ALTER SYSTEM ARCHIVE LOG CURRENT , then oracle write in the journal of the alerts as:

  So my question on what scenario ALTER SYSTEM ARCHIVE LOG will be captured in the log of alerts.
  because it's a mistake to run foreground process ALTER SYSTEM ARCHIVE LOG .

  Have you had a logs archived backup RMAN script which is called ALTER SYSTEM ARCHIVE LOG CURRENT

   RMAN> run
             {
                sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
                backup  archivelog all delete all input;
             }
  

  If you try the command ALTER SYSTEM ARCHIVE LOG CURRENT on stanby, you get error ORA-01109: database is not open. This means database is not open READ/WRITE mode.
  Then we can use ALTER SYSTEM ARCHIVE LOG CURRENT on the standby database.

  Thanks for the interesting thread

• Do we need apostrophes when you set values with ALTER SYSTEM?

  DB version: 11.2, 10.2
  Version: AIX
  
  What logs the values of character with ALTER SYSTEM, do I have to enclose the value within single quotes.
  
  
  Both the below worked. So I'm a bit confused.

  SQL> ALTER system set audit_trail=NONE scope=spfile;
  
  System altered.
  
  -- Tested with single quotes on another DB
  SQL> ALTER system set audit_trail='NONE' scope=spfile;
  
  System altered.

  What logs the values of character with ALTER SYSTEM, do I have to enclose the value within single quotes.

  When you pass several parameters, you can use single quotes, in other cases sound option.

  If you have multiple databases on hold, you must configure by separating with single quotes.
  For example,.
  (1) fal_client = "STBY1", "STBY2", "STBY3" and so on.
  (2) log_archive_dest_2 = "service = stby lgwr async... '

  If you see under SPFILE settings, here, some are mentioned with single quotes & SEC_CASE_SESITIVE_LOGIN is not in quotes. But the value is always the same.

  From SPFILE;

  *.remote_login_passwordfile='EXCLUSIVE'
  *.sec_case_sensitive_logon=FALSE                                       "used NO QUOTES"

  Since you have already issued ALTER SYSTEM KILL SESSION

• Method to identify the user isuing ALTER SYSTEM

  Hi all
  We have a database of test in which APPS (a power user) access is given to all developers. We had kept TIMED_STATISTIC to false in this case, so that the load is reduced to the minimum. From these last days, we change this value at the level of the system, and we are unable to identify the person.
  
  Is there a way I can write a database trigger to capture this specific ALTER SYSTEM event? Any help in this regard is highly appreciated.

  Hi Keita,
  My mistake, I do not pay attention on behalf of the author. Forgive me for my doubts; they may be stupid - I'm not a DBA, but I'm a preparer SQL.

  If I use audit_sys_operations - he will capture all ALTER SYSTEM orders by any user. Then narrow it down us to the test user by issuing ALTER AUDIT test SYSTEM. Please correct me if I'm wrong.

  In my PB, there are at least 300 developers work at the moment - is possible to limit this information to a specific event to ALTER SYSTEM? In addition, we are in a WINDOWs environment. If cron does not work. It would be much better if I could device a method to write the details of the session incriminated at a table.

  There is no problem with the log command. Please refer to the documentation for more information on the syntax 'PLUS ARCHIVELOG '.

  Adding BACKUP... MORE ARCHIVELOG causes RMAN, follow these steps:

  * 1. Executes the ALTER SYSTEM ARCHIVE LOG CURRENT command.*

  * 2. All runs THE BACKUP ARCHIVELOG. Note that if backup optimization is enabled, then RMAN passes the newspapers that he has already saved to the specified device

  * 3. Backup the rest of the files specified in BACKUP command.*

  * 4. Executes the ALTER SYSTEM ARCHIVE LOG CURRENT command.*

  * 5. Backup of all remaining archived logs generated during the backup.*

  This ensures that backups of data taken when the command file is recoverable in a consistent state.

• Using the copy Flash "alter system suspend '"

  Hello friends,
  
  I just had the opportunity to have the IBM/Tivoli to present a new feature called Advanced Copy Services.
  This feature offers the possibility to take a copy of 'flash' very fast to a database (hot water), and then copy it to another partition of HDD or on SAN or network server, and then allows us to use RMAN to perform a normal "flashcopied" database copy The time it takes to make a copy of 'flash' is expressed in only a few minutes. In fact, I would like to know precisely how long it takes for a real database about 300 GB.
  
  The whole point of the software is to eliminate the need for long time for backups.
  
  This sounds good, and I'm trying to understand how this can be done.
  
  Apparently, Oracle has a (fairly new) modifies the system suspend and resume command that makes this possible.
  
  Someone at - he used these change orders in the system for this purpose (flashcopy and backups)? Is it really possible to run for this purpose?
  
  I found a few sites with information on this subject and it seems that this can be done as the seller says.
  When Oracle offer this new feature? I wasn't aware of this.
  
  NOTE: When I did a few tests, I "suspended" the database, yet I could still select tables, but I could not perform any DDL and DML. Apparently suspends performs a form of locking transaction on all objects in the database.
  
  Thank you.

  Is your goal to a backup or a copy of the database?

  I used flash for both, but the Services of integrated advanced copy the Flashcopy and Tivoli Storage Manager with the Protection of data for instant capture devices. I never wanted to integrate Flash copy with Tivoli, my main goal was a brief overview of the database for backup or duplication. I always once a flash for backup just manually send the Flash files to TSM. If there are a few advanages it to integrate Flash and TSM, I have never done.

  I've never used suspends alter system as part of the copy of flash, because it suspends all I/o operations and for copy makes flash a recovery managed on the other end eliminates this need however if your database is large enough with enough file Flash with the suspension systems may not be all that practice because I had a database that took almost 5 minutes to get the flash has started on all of its volumes and the suspension for that length of time I'd be against. However Metro Mirror (PPRC) I think requires suspends, so, according to the technology behind the presences for advanced copy Services may be required esp if the wish is to leave the boundaries of the San to copy/backup however documentation is really taking only about copy flash.

  I would like to ask the question how long will be my database must be in a sleep state? As I have indicated that if the database has a large number of volumes that need to be flashed this might take a bit so if you have a busy database that could be a factor to consider.

  One thing I wonder is if you need to maintain the drive around because the flash back for quick restoration why not only run a physical standby and run backup from it with PDT it will serve the purpse even unloading the backup to another server, and when you re-instantiate the day before use flash for this not to mention some of the other benefits you get to have physics of the day before.

  Then, look carefully the benefits and disadventages of the use of GBA in your environment based on your needs and your requirements.
