• Oracle Redo Log activity

  Hi members,
  
  I have an Oracle database instance where the log files continue to grow even when there is no activity of the use of the application.
  What I noticed it seems to be some model of frequency as to where this newspaper activity occurs.
  My question is, is there any default Oracle process or to the demand for jobs that will result in the generation of this log data.
  
  
  Thank you
  Alan

  Hello
  You will have many background running processes and that they generate text-based newspapers. You for example MMON, automatic backups (if enabled), 11g you have autotask process which tune top sqls, collect stats etc. Then, even when nobody connects to the db you'll always some activities there.

• Difference between redo logfiles, Undo Tablespace, Archive log data file

  Can some please highlight the difference between Undo and Redo Logs
  Also why we need to separate the archive logs when the recovery log data can be written directly in data files...
  
  Help you will be highly appreciated...

  Hello

  Ed gave you a very good answer.

  Rememeber database files are online and they are written to by DBWR process. So we have the database files, redo log files and archive logs.
  In order to avoid all the crawl log when you perform a recovery, database performs control points that summarize the State of the database. This operation of control point provides a shortcut to the recovery. At the checkpoint, the database knows that all incorrect pages were written to disk (for example, database files). At the time of recovery, the log (which includes-finished and unfinished transactions) is used to bring the database to a consistent state. The system locates the time of the last checkpoint and returned to this position in the log file. Then he restores forward all completed transactions (read committed) that occurred after the last checkpoint and rolls back all transactions that were not committed, but that began before the last checkpoint. This is where online log files are used.

  Now imagine that you need to back up your database GB 100 + all 10 minutes. It would be a waste of space! So you take a backup of your database at time t and backups of archiver process redo logs periodically to check the newspapers so that redo log files can be replaced and RMAN will use the last backup and archive the log files to recover your database at the time.

  Now, I mentioned the checkpoint process. The Checkpoint process regularly launches a control point that uses DBWR to rewrite all the blocks Sales in the data files, so synchronize the database. Imagine one dam is running and have exhausted all the redo log files. At this point, Oracle will wait until all Sales already queued blocks have been written to the buffer on disk (database files) foremost him redo log files can be considered as superfluous and available for re-use (i.e. can be overwritten). This will result in the following message in the alert.log:

  Thread 1 advanced to log sequence 17973
    Current log# 3 seq# 17973 mem# 0: /oracle/data/HAM1/log3aHAM1.dbf
    Current log# 3 seq# 17973 mem# 1: /oracle/data/HAM1/log3bHAM1.dbf
  Thread 1 cannot allocate new log, sequence 17974
  Checkpoint not complete

    Current log# 3 seq# 17973 mem# 1: /oracle/data/HAM1/log3bHAM1.dbf
  Thread 1 advanced to log sequence 17974
  

  I am sure you have done the following:

  alter database mount;
  
  Database altered.
  

  When you mount a database, Oracle combines the instance started the database. Oracle control files are opened and read. However, no checking such as the restore/recovery is performed

  alter database open;
  
  Database altered.
  

  An open command opens the data files, recovery logs, it performs automatic and consistency of database recovery. At this point, the database is now ready to be used by all valid users.

  HTH,

  Mich

• Standby redo logs

  Hi all

  For the installation of dataguard, supposed to docs create standby redo logs on the standby server.

  It does not mention to create logs to redo waiting on the primary server.

  So what happens if I pass of the day before?

  Then my primary db now becomes the day before db. But there is no waiting for redo logs?

  Kindly shed lights...

  Thank you very much

  Hi Sysas and ALL,

  the rule is to create a group of newspapers waiting to roll forward pending Eve more than the number of redo log group in the primary.

  Do you mean > the rule is to create a group of newspapers waiting to roll forward pending Eve more than the number of the Group of online redo logs in the primary?

  So, if I have 3 ONLINE redo log groups and 4 STANDBY redo log at the primary level, 3o + 4 s = 7

  I'll create 3 groups of online redo logs and 1 redo log group ENSURES the standby?     3O + 1 s = 4

  Why not just create everything as even with the main number?  3O + 4 s = 7 for sleep?

  Thank you.

  Sorry... If you have 3 groups of newspapers online redo (in primary and standby), and then create 4 STANDBY redo record groups (primary and standby).

• How to uninstall Oracle Database 11 g release 2?

  Hello
  I want to uninstall Oracle Database 11 g release 2.
  
  Im running the deinstall.bat that is located on:
  C:\app\MachineName\product\11.2.0\dbhome_2\deinstall
  
  then in the command window, I get this message:
  Specify all headphones single instance that must be configured out [LISTENING]:
  
  What should I enter here?
  What is an auditor?
  
  Thank you...

  Generally, the default value (BACKSPACE) is correct.

  The listener is the network feature which helps you connect. He listens to new connection attempts.

  I like to think it's a traffic COP that allows a connection, but has nothing to do with later.

  The listener is a named process that is running on the Oracle server, waiting for requests from the client to connect to the Instance.

  The listener does not normally handle connections once the original request was made. The listen listen on a default port is 1521.

• Thread 1 cannot allocate new logs, 714 - Checkpoint sequence is not complete

  Thank you in advance,

  This message indicates that Oracle wants to re-use a redo log file, but the current position of the control point is always in this newspaper. In this case, Oracle must wait until the position of the control point passes this newspaper. Because the objective of additional control point never accused tail current log more than 90% of the smallest size of log file, this situation might be met if DBWR writing too slowly, or if a log switch occurs before the log is completely filled,
  or if the size of the log files is too small. When the database is waiting on the checkpoints, redo generation is stopped until the journal is made.

• Data Guard CARS

  Hello
  is there a special configuration or guidelines to the configuration data guard on an Oracle cluster database, or as the only forum?
  Thank you very much

  Hello

  Do you want to say that each instance on a cluster to own his own spfile, and I need to change each separately spfile to redo waiting for shipment?

  All cluster database instances must use the same shared spfile... You can also change the spfile... you will have to update using the command:
  alter system set parametername = value scope = spfile sid = InstanceName

  My second question is that each instance generates its own recovery logs to archive, so should not be that database waiting to be ordered into clusters, no? It will applied logs coming recovery for any instance of cluster, is that correct? even if it's only one not clustered instance Eve...

  You can have a single instance watch and all the newspapers all primary levels will apply to it...

• How to display the charging icon when updating of charts

  Hello

  in my actual page, I have an IR and a chart based on the data presented in the ir. When the user applies a filter in the ir, the data in the chart changes. to achieve this, I retrieve the State of the ir filter, rebuild the graphical application, a refreesh in a DA triggered after the update of the IR region.

  So far so good. now my problem:

  the graphical query is sort of a long walk. This means that it takes about 30 seconds to get the data. First, the graph is displayed, it said "loading data". so that the user knows that he (or she) have to show patience.

  but during the refreshing of the region of cat and re - run the query the old values are presented. as long as the new query is running. Once the query has been completed, the table is updated, new data are presented.

  what I want is to give the user some sort of information, new data are loaded. either by disabling the table before you start the new query, either by showing any sort of reload the icon or the text.

  can you give some advice my way to reach one or other purpose?

  Greetings

  Peter

  (APEX 4.2)

  Hello yeti.

  In your DA trigger "discount for after ' IR in which you rebuild the query and refresh the chart area:

  • Add/before the first chart refresh 'Real' action 'Execute JavaScript code' with the code like:

  apex.widget.waitPopup();
  

  • Add the last 'Real' action "Execute JavaScript Code to the code like:

  $('#apex_wait_popup').remove();
  $('#apex_wait_overlay').remove();
  

  It will show the Oracle APEX waiting popup with loading image and an overlay to disable the interaction of the user with the page until your DA runs and then remove the popup of waiting and the cache.

  Kind regards

• Functions in the rules of Foglight

  Hello

  I tried to find the definitions of the custom functions used in the rules, but have failed so far. Can someone guide me in the right direction?

  For example: DBO - redo wait Contention
  Function used: DBWC_SingleInstanceOnlyRuleFilter (scope, "DBO - Redo Wait argument", "3", status);

  I need to understand that, in order to take advantage of the features within my rules as well as to better understand the existing rules.

  P.S. I'm aware of the use of the functions with WCF dashboards.

  Thanks in advance

  Hi Ashley.

  These types of features used in the Foglight rules are said to be "named scripts. They are different from the functions used in the WCF dashboards. They are often deployed in Foglight via a cartridge, especially when a rule provided by this cartridge uses the script. Once a named script is within Foglight, other rules may use it.

  You can't see the source code of a script within the Foglight user interface.  If you want to see the source for such a script, the best approach is to understand what Foglight cartridge, it was deployed in, then make a copy of the file of the cartridge and crack open the copy with WinZip or WinRAR - you will probably be able to locate the source of the script here in a XML political oversight.

  I hope this helps.

• No. before the value in the log file for the PK column on updates

  I can't seem to get 'before' values for columns which are PK appears in my trail files.  For example: when playing with a velocity template:

  #foreach ($op in $tx)

  #foreach ($col in the $op)

  front: $col.getBeforeValue)

  After: $col.getAfterValue)

  #{end}

  #{end}

  ... If the operation is an INSERT, then the values for all columns in the later, so the INSERTS are very well.

  If the operation is a DELETION, then the value of column PK * fact * appear in the front, if DELETIONS are fine.

  ... If the operation is an UPDATE, then the PK column value does * not * appear in both the front or after, if updates are broken.

  I tried to set the following in the parameters to my snippet... each with no change in the results:

  I run OGG Capture for Oracle Version 11.2.1.0.3 on Solaris, sparc 64-bit on the OGG is running against my DB Oracle redo logs.

  I'm under OGG Capture Version 11.1.1.0.0 on Solaris, sparc 64-bit of the system on which I am pumping files path, against which I'm reading the front of values in a userexit, as described above.

  Thanks for the tips / pointers.

  In order to get the PK column for an update, you must add an additional newspaper group that includes the primary key columns with the GGSCI ADD TRANDATA command. This is discussed in the Oracle GoldenGate Oracle installation and Guide in the section "To enable additional logging at the level of the table", found here:

  http://docs.Oracle.com/CD/E22355_01/doc.11111/e21406.PDF

  A combination to add TRANDATA and GETUPDATEBEFORES, you should get what you want. Here's more information:

• Reading user output pump extract path fails to start

  I have the following environment:

  Oracle DB on system A

  GG for DB Oracle installation on the system has (GG)

  GG for Java installation on system B (GG (B)

  I have a srcDb extracted under GG who bed the Oracle redo logs and generates files path on the system.

  I have a pumpDb extracted under GG it pumps the srcDb trail on a remote trail on system B

  I am trying to configure an excerpt uePump running under GG B on system B to read in the files of trail that GG A pumped on him in an exit from the user... but I'm crashes with the following error when you try to start uePump on GG B installation:

  Mgr.PRM: EXCERPT from UEPUMP.

  uepump.PRM: EXCERPT from UEPUMP.

  uepump.PRM:problem on line 27.  File, table, or record expected definition.

  uepump.PRM: PROCESS ABENDING.

  I have a sourcedefs variable in my uepump settings, and I can check it is finding/reading the file (... by naming evil in settings and seeing complain).  I generated the definition file using the defgen on the installation of A GG on the host and FTP'd the file system B system.  I'm assuming that the line number mentioned in the above error refers to the definitions file.  Line 27 of this file is:

  Type of database: ORACLE

  ... and this is also the first line of 'no comment' the definitions file (... assuming that the comments in the files defgen start with an asterisk... *)

  This is a problem between versions of GoldenGate of GG facility A and B GG?

  GG (which defgen generated definitions) is:

  Oracle GoldenGate V11.2.1.0.3 for Oracle 11 g 64 bit on Solaris 9/10

  GG B (where I see the error when you try to read the definition file is:)

  Oracle GoldenGate V11.1.1.0.0 for Java on Solaris 64 bit

  Any help or advice is appreciated.

  Yes, this error has been observed when there are differences between the formats between DEFGEN versions. This is discussed in the following article in the knowledge on MOS:

  Replicat abend OGG-00303 ERROR problem on line xx. File, table, or record expected definition. (Doc ID 1455370.1)

  11.2 Ogg, there is a new parameter NOEXTATTR. It is used in DEFGEN. When the OGG version in a target site is smaller than the source site, defgen must use the NOEXTATTR parameter to generate a sourcedef file target what site can read. If you use a sourcedef without NOEXTATTR file, a replicat abend with error 00303

  So, there are two ways to work around the problem:

  1. use a paramfile defgen with NOEXTATTR option, or

  2. generate the definition file with the same OGG version as the version of site target OGG.

  Best regards
