Local capture only seems to process archived logs - not online logs

In Oracle 10g R2 I have set up a local capture and apply on a logical standby database. I am configured to capture table level changes with LOGFILE_ASSIGNMENT = IMPLICIT, but the capture process only seems to find changes when the local redo logs are archived. I read that local capture will try to read the online redo if it can and then resort to the archive log. I don't see anything on why the online redo couldn't be used (except if LOGFILE_ASSIGNMENT = EXPLICIT). I want the capture to read the online redo rather than waiting for an archive. Can you help me? The status of the capture shows "WAITING FOR REDO" until archive time.

Anybody else ever experience this?

Two copies archive logs with only one defined

Hi,
On a 11g database, I have only got flash_recovery_area defined. When switched into archive log mode, I have expected only one copy of archive logs produced in the defined USE_DB_RECOVERY_FILE_DEST location, but there is another copy generated as well under $ORACLE_HOME/dbs directory. How to explain that? and how to DISABLE the second copy to be produced?
Thanks for any help

This is the way 11g install sets up the archive destination intially after creating the database using DBA.
What you can do is to go to the Recovery Settings in Enterprise Manager. You would notice that Archive Log Destination number 1 is set to usr/oracle11g/R1/dbs/arch while number 10 is set to USE_DB_RECOVERY_FILE_DEST
Remove the entry for Number 1 (leave it blank). Apply the settings. This will force Oracle to only log to flash_recovery_area.

Archive Log vs Full Backup Concept

Hi,
I just need some clarification on how backups and archive logs work. Lets say starting at 1PM I have archive logs 1,2,3,4,5 and then I perform a full backup at 6PM.
Then I resume generating archive logs at 6PM to get logs 6,7,8,9,10. I then stop at 11PM.
If my understanding is correct, the archive logs should allow me to restore oracle to a point in time anywhere between 1PM and 11PM. But if I only have the full backup then I can only restore to a single point, which is 6PM. Is my understanding correct?
Do the archive logs only get applied to the datafiles when the backup occurs or only when a restore occurs? It doesn't seem like the archive logs get applied on the fly.
Thanks in advance.

Thanks for the great explanation! So I can do a point in time restore from any time since the datafiles have last been written (or from when I have the last set of backed up datafiles plus the archive logs). From what you are saying, I can force the datafiles to be written from the redo logs (by doing a checkpoint with "alter set archive log current" or "backup database plus archivelog"), and then I can delete all the archive logs that have a SCN less than the checkpoint SCN on the datafiles. Is this true? This would be for the purposes of preserving disk space.Hi,
See this example. I hope this explain your doubt.

Oracle 10g - switch off archive logs

Hi,
I understand in oracle 10g, the following parameter is not longer available:
LOG_ARCHIVE_START=FALSE
Can i confirm that for now, only way to disable archive log is to execute the following command when in mount stage:
alter database noarchivelog;
There's not other parameter we can specify in pfile to disable it permantely?
thanks

You are correct. No other parameters.

Capture process issue...archive log missing!!!!!

Hi,
Oracle Streams capture process is alternating between INITIALIZING and DICTIONARY INITIALIZATION state and not proceeding after this state to capture updates made on table.
we have accidentally missing archivelogs and no backup archive logs.
Now I am going to recreate the capture process again.
How I can start the the capture process from new SCN ?
And Waht is the batter way to remove the archive log files from central server, because
SCN used by capture processes?
Thanks,
Faziarain

Using dbms_Streams_Adm to add a capture, perform also a dbms_capture_adm.build. You will see in v$archived_log at the column dictionary_begin a 'yes', which means that the first_change# of this archivelog is first suitable SCN for starting capture.
'rman' is the prefered way in 10g+ to remove the archives as it is aware of streams constraints. If you can't use rman to purge the archives, then you need to check the min required SCN in your system by script and act accordingly.
Since 10g, I recommend to use rman, but nevertheless, here is the script I made in 9i in the old time were rman was eating the archives needed by Streams with appetite.

                       -z Check if log is still needed by logminer (used in streams),
                                it requires -i <sid> and also -g for Oracle 8i
              This program list, delete or move half of all file whose extention is given [ or default 'arc']
              It check the size of the archive directory and if the percentage occupancy is above the given limit
              then it performs the action on the half older files.
        How to use this prg :
                run this file from the crontab, say, each hour.
     example
     1) Delete archive that is sharing common arch disk, when you are at 85% of 2500 mega perform delete half of the files
     whose extention is 'arc' using default affected file (default is -r 2)
     0,30 * * * * /usr/local/bin/watch_arc.sh -e arc -t /arc/POLDEV -s 2500 -p 85 -d -v /var/tmp/watch_arc.POLDEV.log
     2) Delete archive that is sharing common disk with oother DB in /archive, act when 90% of 140G, affect by deleting
     a quater of all files (-r 4) whose extention is 'dbf' but connect before as sysdba in POLDEV db (-i) if they are
     applied (-f is a dataguard option)
     watch_arc.sh -e dbf -t /archive/standby/CITSPRD -s 140000 -p 90 -d -f -i POLDEV -r 4 -v /tmp/watch_arc.POLDEV.log
     3) Delete archive of DB POLDEV when it reaches 75% affect 1/3 third of files, but connect in DB to check if
     logminer do not need this archive (-z). this is usefull in 9iR2 when using Rman as rman do not support delete input
     in connection to Logminer.
     watch_arc.sh -e arc -t /archive/standby/CITSPRD -p 75 -d -z -i POLDEV -r 3 -v /tmp/watch_arc.POLDEV.log

CAPTURE process error - missing Archive log

Hi -
I am getting cannot open archived log 'xxxx.arc' message when I try to start a newly created capture process. The archive files have been moved by the DBAs.
Is there a way to set the capture process to start from a new archive ?
I tried
exec DBMS_CAPTURE_ADM.ALTER_CAPTURE ( capture_name => 'STRMADMIN_SCH_CAPTURE', start_scn =>9668840362577);
I got the new scn from DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();.
But I still get the same error.
Any ideas ?
Thanks,
Sadeepa

If you are on 9i, I know that trying to reset the scn that way won't work. You have to drop and recreate the capture process. You can leave all the rules and rulesets in place, but I think you have to prepare all of the tables again.

Source DB on RAC, Archived Log Downstream Capture:Logs could not be shipped

I don't have much experience in Oracle RAC.
We are implementing Oracle Streams using Archived-Log Downstream capture. Source and Target DBs are 11gR2.
The source DB is in RAC (uses scan listeners).
To prevents, users from accessing the source DB, the DBA of the source DB shutdown the listener on port 1521 (changed the port number to 0000 in some file). There was one more listener on port 1523 that was up and running. We used port 1523 to create DB link between the 2 databases.
But, because the listener on Port 1521 was down, the archived logs from the source DB could not be shipped to the shared rive. As per the source DB DBA, the two instances in RAC use this listener/port to communicate with each other.
As such, when we ran DBMS_CAPTURE_ADM.CREATE_CAPTURE procedure from the target DB, the Logminer Data Dictionary that was extracted from the source DB to the Redo Logs was not avaialble to the target DB and the streams implementation failed.
It seems that for the archived logs to ship from the source DB to the shared drive, we need the listener on the port 1521 up and running. (Correct me if I am wrong ).
My question is:
Is there a way to shutdown a listener to prevent users from accessing the DB and have another listsener up so that the archived logs can be shipped to the shared drive ? If so, can you please give the details/example ?
We asked the same question to the DBA of the source DB and we were told that it could not be done.
Thanks in advance.

Make sure that the dblink "using" clause is referencing a service name that uses a listener that is up and operational. There is no requirement that the listener be on port 1521 for Streams or for shipping logs.
Chapter 4 of the 2Day+ Data Replication and Integration manual has instructions for configuring downstream capture in Tutorial: Configuring Two-Database Replication with a Downstream Capture Process

How do I setup RMAN not to delete archive log files on the source database so GoldenGate can process DDL/DML changes?

I want to setup RMAN not to delete any archive log files that will be used by GoldenGate.   Once GoldenGate is completed with the archive log file, the archive log file can be backup and deleted by RMAN.   It's my understanding that I can issue the following command "REGISTER EXTRACT <ext_name>, LOGRETENTION" to enable to functionally.   Is this the only thing I need to do to execute to enable this functionally?

Hello,
Yes this is the rigth way using clasic capture.
Using the command : REGISTER EXTRACT Extract_name LOGRETENTION.
Create a Oracle Streams Group Capture (Artificial) that prevent RMAN archive deletion if these are pending to process for Golden Gate capture process.
You can see this integration doing a SELECT * FROM DBA_CAPTURE; after execute the register command.
Then, when RMAN try to delete a archive file pending to process for GG this warning appear AT RMAN logs:
Error:     RMAN 8317 (RMAN-08317 RMAN-8317)
Text:     WARNING: archived log not deleted, needed for standby or upstream capture process.
Then , this is a good manageability feature. I think is a 11.1 GG new feature.
Tip. To avoid RMAN backup multiples times a archive pending to process, there is a option called BACKUP archivelog not backed 1 times.
If you remove a Capture process that is registered with the database you need to use this comand to remove the streams capture group:
unREGISTER EXTRACT extract_name LOGRETENTION;
Then if you query dba_capture, the artificial Streams group is deleted.
I hope help.

Archive log miss : How to restart capture

Hi Gurus,
I configured hotlog CDC distributed on 10.2.0.4 Databases.
I make a mistake: in my source Db I have deleted an Archive log,
and now the state of Capture process in V_$STREAM_CAPTURE is "WAITING FOR REDO: LAST SCN MINED 930696".
Now I'd like to restart the capture process from the next archive (just after the missed archive)
How is it possible?
tnk Fabio

I'm sorry to tell you that, but it's not possible. (Just as it's not possible to recover database with missing logs...)
You will have to recreate the capture process and to re-instantiate the replicated tables.
Regards,

Question about only new archive logs backed up in backup

Hi,
We are taking daily two online backup. We are running database in ARCHIVELOG mode. We configure database in PRIMARY and PHYSICAL STANDBY mode. Till now, we were taking all archive logs in backup. But it was causing problem of lot of space utilization of disk.
So based on search in this forum, I am planning to take only new archive logs generated since last backed up using following command.
BACKUP ARCHIVELOG all not backed up 1 times format '$dir/archivelogs_%s_%t' FORCE;
I am not sure about how it impact during restore and recovery when we take only new archivelogs in backup.
We restore database and then after perform always incomplete recovery till latest SCN capture in backup using following commands.
RESTORE DATABASE;
RECOVER DATABASE UNTIL SCN $BACKUP_LAST_SCN;
Do you see any problem/risk of implementing this solution going ahead?
Please let me provide your thoughts/inputs for this.
Thanks.

Hi,
We are not deleting archive logs from actual location after backup. We keep latest 6 days archive logs at actual location. But here we are planning to put only new archive logs in backup image which were not backed up due to disk size problem.
For your reference below is our datbase backup RMAN commands. We are taking full database backup.
run {
ALLOCATE CHANNEL C1 TYPE DISK;
delete noprompt archivelog all completed before 'sysdate-5';
SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';
BACKUP INCREMENTAL LEVEL=0 CUMULATIVE format '$dir/level0_%u' DATABASE include current controlfile
for standby force;
SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';
BACKUP ARCHIVELOG all not backed up 1 times format '$dir/archivelogs_%s_%t' FORCE;
BACKUP CURRENT CONTROLFILE format '$dir/control_primary' FORCE;
Then in this polich do you see any problem when we restore database as PRIMARY or PHYSICAL STANDBY on server. We are using Oracle 10.2.0.3.

How do I retrieve call history from my iPhone 4S? It only seems to log for about a month and I need an earlier date?

How do I retrieve call history from my iPhone 4S? It only seems to log for about a month and I need an earlier date?

If you have backup of your files, you can get your call history back as long as you sync iPhone with iTunes frequently.
OK, the first thing you are required to do is close the function of "prevent iPhone from syncing automatically." in iTunes, avoiding to sync iPhone again.
Now, connect your iPhone to pc and open iTunes.
iTunes> preferences> devices
All the backup data in iTunes will be displayed.
Then,click the File menu and select Devices > Restore from Back up
your iPhone will restart and you can find them back.
This method only can find back the latest history, to get back the old, you should turn to a third party program for help.

Is the only way to import large amount of data and database objects into a primary database is to shutdown the standby, turn off archive log mode, do the import, then rebuild the standby?

I have a primary database that need to import large amount of data and database objects. 1.) Do I shutdown the standby? 2.) Turn off archive log mode? 3.) Perform the import? 4.) Rebuild the standby? or is there a better way or best practice?

Instead of rebuilding the (whole) standby, you take an incremental (from SCN) backup from the Primary and restore it on the Standby. That way, if, for example
a. Only two out of 12 tablespaces are affected by the import, the incremental backup would effectively be only the blocks changed in those two tablespaces (and some other changes in system and undo) {provided that there are no other changes in the other ten tablespaces}
b. if the size of the import is only 15% of the database, the incremental backup to restore to the standby is small

Archive a FCP Project to DVD (with used captures only)

Is there a way to backup a project with USED Captures only.
So, the FCP file with the used captures, delteing all the unused captures.
Would be a great option to use or make correction in the future!

Backing up to DVD is probably the worst type of archive, not just because of the limited data space available but because the disks do deteriorate as a vastly increased speed compared to tape.
Even hard drives, if used for archiving and just left on a shelf can fail because they are not used!
Tape is still the best and most reliable.
We've been experimenting with Bluray data backups but of course, always have a tape back up on top of that!

Is RMAN only way to take backup and delete Archive Logs?

On primary db:
===============
OS: Windows 2003 server 32-bit
Oracle: Oracle 10g (10.2.0.1.0) R2 32-bit
On Physical standby db:
===============
OS: Windows 2003 server 32-bit
Oracle: Oracle 10g (10.2.0.1.0) R2 32-bit
Data Guard just configured. Archive Logs are properly being shipped to standby db. Is RMAN only way to take backup and delete Archive Logs from both primary and standby db? What other command can be used?
Thanks

No, but anything else is way more work. Without using RMAN you would have to find another way to keep track of applied logs.
RMAN make this very simple :
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;Using another method would be like using the handle of your screwdriver as a hammer.

Local capture only seems to process archived logs - not online logs
