Log gap detection WITHOUT Dataguard
Heys,
I am looking for a solution to keep my standby database up2date.
I set up the enviroment according to http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10g_RACPrimaryRACPhysicalStandby.pdf
The RedoLog Apply works fine.
But how can I ensure that log are re-transfered so that no gaps come up.
Is there a way to manually configure this ?
Thx for your help
Christian
Check this script
SELECT LOCAL.THREAD#, LOCAL.SEQUENCE# FROM (SELECT THREAD#, SEQUENCE# FROM V$ARCHIVED_LOG WHERE DEST_ID=1) LOCAL WHERE LOCAL.SEQUENCE# NOT IN (SELECT SEQUENCE# FROM V$ARCHIVED_LOG WHERE DEST_ID=2 AND THREAD# = LOCAL.THREAD#);
Go for real time apply

Physical standby without dataguard
Naive question.
I am going thru metalink note (374069.1) on how to create a physical standby. In that note, they didn't mention data guard stuff. Am I to assume that physical standby without dataguard can be created?
Thanks.It might appears to be easy to create psuedo standy but you will have hardtime to simulate the automatic archive log apply and gap resolve.
Plus the level of data availability provided by self-managed standby can't come close to Data Guard can offer.
With Data Guard you can almost get zero data loss between Primary and Standy, depends on your redo logfile size there could be many data in online redo logs. -
Hello all,
I have one query regarding Gap detection & resolution.
1) On a 10.2.0.4 DB with physical standby, gap detection and resolution happened using automatic gap resolution without setting FAL_server and FAL_Client on the standby. So I would like to know why should one set the said parameters?
Thanks and regardsWell, please refer to below link
http://docs.oracle.com/cd/B19306_01/server.102/b14239/log_transport.htm#i1268281
it's says that automatic gap resolution doesn't require any setting but primary should be available. For FAL_SERVER, you can specify name for other standby by , oracle stream also from where you can get the archive log too, in case primary not available for some reason.
Thanks

Hi,
I've successfully created a standby for a single node Primary Database in 10g on Redhat Enterprise Linux 4.0 Update 4.0. I'm planning to add one more standby site to the same primary database. Now, my question is...
1. Is it possible to setup more than one standby without the help of DataGuard.
2. If possible, please guide me how to do it(step-by-step).
Thanks in advance...
MaheshIf you've already configured one Standby without DataGuard, you'd use the same method for the second standby.
Since we do not know your scripts and how you are propagating archive logs and putting the standby in recovery mode -- all of which would be "custom" methods in the absence of DataGuard -- we can't really advice you . Because it is difficult to advice on extensions to a customisation without looking at a customisation.
Many sites have implemented a scripted Standby without DataGuard using methods available since Oracle7. However, the frequency and method of archivelog propagation and how and when the standby database "wakes up" to apply the archivelogs etc are all site specific.
Let's say that you DO use the ARCH process on the primary database to propagate archivelogs to the Standby destination site. Since Oracle 10g allows multiple log_archive_dest_n sites, you can just add one more site and have the archivelogs propagate to the additonal site. However, there are other parameters (eg MANDATORY/OPTIONAL, REOPEN, DELAY etc) that you would set based on your requirements.
The two standby instances would be independent {unaware} of each other -- you can script delays between the archivelogs so that the two standby aren't always at the same level (this allows "fallback" to an "older version of the database" when necessary). You could have one standby stop recovery and open read only for some time.
Short Answer : Yes, it is possible to have multiple "standby"s without DataGuard.
Correct Answer : How you do it depends on how you want to extend your current implementation.

Hi all.
Oracle 9i ( SE )
I'm trying to figure out how to create a standby database without dataguard. I've read that its possible, but I can't find any documentation on exactly how to do it. From what I've gathered I should be able to
Create a duplicate database from primary backups
Put standby database into "some recovery mode" - this is the bit I'm stumped at
Copy archive logs from primary to standby, where they will magically be applied?
I need to migration lots of datafiles to new disks, and cannot afford the downtime to just move them, so I'm thinking the best way to do it is to create a standby and keep it as close to synced to the primary as possible, then shutdown primary, apply file logs, point primary to the new datafile location..
Can anyone either point me to a good article on doing standby with dataguard, or if there is a better way to move large ( move procedure will take about 4-5 hours) tablespaces/databases with minimum downtime.
Thanks.Hrmm, maybe? so is "Data Guard" by itself available for SE?
When I startup the database it reports
"Oracle Data Guard is not available in this edition of Oracle."
I'll go poke around that document too.
btw. the document I read which suggests this is possible is, http://www.dba-oracle.com/oracle_tips_failover.htm
Thanks

Hey, in my configuration I found a log gaps dated two months ago.
Since april logs are transfered to my physical standby, but are not applied, due to the log gap.
I am wondering, why dataguard is not coming up with an error.
I was expecting a message like: Database not up to date --- or something like this...
When I query the configuratin it still comes up with: SUCCESS
Event the show databae verbose command replies with SUCCESS
Is that an expected behaviour ?
ChristianI assume that during the transfer of the logfile something went corrupt, as the asm instance failed.
Now the logfiles already deleted by the retention policies, so no way to get the redologs back to the system.
But anyway, I was expecting to get a message in the broker configuration that the standby is not up to date :-(

Forced Due to Logging Gap what does this mean
It seems to be new in SP 2013 that when monitoring the ULS logs there are large instances of the phrase
Forced due to logging gap :
Can someone advise as to the exact meaning of this? There are extremely few references on the net, only a few examples of people posting their ULS entries for unrelated questions.
Seems a bit odd as it is extremely common in our logs - kind of a bummer as it must contribute a measurable amount to log file size bloat.

I’ve found what it’s doing but not how to modify the behavior. In the Microsoft.SharePoint.Diagnostics.ULS class there is a private method called “HandleLoggingGaps”.
This method is called before trace data is sent to the log in several of the core logging methods. When called, it checks both the LastSkippedTraceTime value and the last traced time in the current correlation context plus a variable called MaxLoggingGap
against the current date/time.
The MaxLoggingGap value is set by default to 50 milliseconds but there is an environment variable “_ULS_MAX_LOGGING_GAP_IN_MILLISECONDS_” that it will use instead
if that variable contains a value. This would seem to indicate that the gap time is configurable but I have yet to find the setting that will do so. I did some reflecting of the powershell cmdlets but so far not found any direct correlation (although
EventLogFloodProtectionQuietPeriod and EventLogFloodProtectionNotifyInterval in the set-spdiagnosticconfig cmdlet look promising).

Standby log files in Oracle Dataguard
Hi,
What is the difference between standby log files and online redo log files in a Dataguard environment?
What is the use of standby log files?
Thanks,
Charith.You're probably familiar with the Online Redo Logs (ORLs). Transaction changes are written from the Log Buffer to the ORLs by the LGWR process.
If you are setting up a physical standby, then you will want to create Standby Redo Logs (SRLs) in the standby database. When SRL's are in place, a process called LNS will transport redo from the Log Buffer of the primary to the RFS process on the standby which will write the redo to the SRLs. If the SRL does not exist, RFS can't do this. The biggest benefit of using SRLs is that you will experience much less data loss, even in MAX PERFORMANCE mode. Redo will constantly be shipped. You won't have to wait for ARCH to transport a full archived redo log.
Cheers,
Brian -
Archive log gap is created is standby when ever audit trail is set to DB
Hi
I am a new dba. I am facing a problem at production server that whenever audit_trail parameter is set to db , archive log gap is created at the standby site.
My database version is 10.2.0.4
Os is windows 2003 R2
Audit_trail parameter is set to db only in primary site, after setting the parameter as db when I bounced the database and switched the logfile , archive log gap is created in the standby..I am using LGWR mode of log transport.
Is there any relation beteen audit_trail and log transport ?
Please note that my archive log location of both the sites has sufficient disk space and the drive is working fine.Also my primary and standby is in WAN.
Please help me in this.Any help will be highly appreciated.
Here a trace file which may be helpful to give any opinion.

Are The SDU/TDU settings are configured in the Oracle Net files on both primary and standby ? I will see if I have an example.
The parameters appear fine.
There was an Oracle document 386417.1 on this, I have not double checked if its still available. ( CHECK - Oracle 9 but worth a galance )
Will Check and post here.
I have these listed too. ( Will check all three and see if they still exist )
When to modify, when not to modify the Session data unit (SDU) [ID 99715.1] ( CHECK - still there but very old )
SQL*Net Packet Sizes (SDU & TDU Parameters) [ID 44694.1] ( CHECK - Best by far WOULD REVIEW FIRST )
Any chance your firewall limit the Packet size?

Physycal Standby archive log gap....
Archive log gap caused... The reason being before the logs can be shipped to standby location where deleted by rman backup... So restored the archives on primary database site back again... These old logs from the gap are not getting shipped to the standby site, but the new ones generated currently are getting shipped.
Can some one help what action do I have to take to resolve the gap? And how to know what's causing and not letting this shipping happen?
Or shall I manually ship these gap archive logs to the standby site?1) Yep running 9i.. But still its not shipping...Are FAL_CLIENT & FAL_SERVER parameters are defined at standby level?
If not, define them at standby level. Those parameter will help to get missing (gap) archives from primary database.
2) If so shipped manually do have to register the archive logs? Just copy from primary to standby and don't need to register any gap, that was in 8i and when there was no background process MRP (media recovery process). If the standby database is in auto media recovery, then, it will automatically applies all the archived logs.

How to create physical standby database without dataguard
Hi,
Can anyone please help me how to create Physical Standby Database without dataguard. As i am using Oracle 10.2.0.1 Standard Edition for production databases.
Please find the specifications of my server :
Database : Oracle 10.2.0.1(Standard Edition)
Server : Linux 4.0(32 bit machine)
As we know that Dataguard cannot be created in Standard Edition as we dont have that option in this edition. So please help me how to create the physical standby database.
Thanks in advance.

Hi,
Our reports run very slow in SharePoint Integrated mode. I look at the logs and I see that for one report request there are bunch of "Forced due to logging gap" rows. Is it some kind of a configuration issue or is it working as it should. Below
is the full log for one report request. I have no admin experience at all and I am confused what each one in the logs mean. I have made some of them in bold font as I suspect it is some kind of configuration issue there. Could you please help understanding
those logs?

Thank you.That is likely the case as native mode is quicker than SharePoint-integrated.
A couple of things to check, and perhaps change if you can:
1) Make sure the latest SSRS ReportViewer is deployed to the SharePoint WFEs. This does not have to match your SSRS deployment version. See http://msdn.microsoft.com/en-us/library/gg492257.aspx
for the compatibility table.
2) If possible, move SSRS to the same SharePoint servers that end users interact with (e.g. the "WFEs").
3) Make sure the underlying server hosting SharePoint has C-States disabled (these are Intel C-States, e.g. C1, C2, C3... aka processor sleep states). If the server has any sort of power regulation, make sure it is at maximum performance (rather than some
form of power saving).
4) Make sure the underlying Windows OS has it's Power Management set to Maximum, rather than any sort of power savings.
You can review the execution logs in the Reporting Services database. Take a look at the ExecutionLog3 view. Compare the TimeProcessing (time it takes to process the report) and TimeRendering (time it takes for the processed report to render to the end user).

How to know the delay in redo log apply on Active Dataguard 11g
Hello All,
How to know the delay in redo log apply on Active Dataguard 11g...
Do we need to wait till log switch occurs?
Or is it recommended to schedule a log switch every 15 min, no matter data is updated/inserted or not in primary?
Please suggest...
Oracle : oracle 11g Release 2
OS : RHEL 5.4
Thanks

Next,
From primary:-
SQL> select thread#,max(sequence#) from v$archived_log group by thread#;
THREAD# MAX(SEQUENCE#)
1 29680
From standby:-
SQL> select thread#,max(sequence#) from v$archived_log where applied='YES' group by thread#;
THREAD# MAX(SEQUENCE#)
1 29680
What is the redo transport service you are using? is it LGWR or ARCH ?
Output of query select * from v$parameter where name like 'log_archive_dest_2' shows below value...
SERVICE=b_stdb LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=b_stdb
So is it lgwr already configured...? if yes then how do i see the delay in both servers..
Yes, the network is good as they both resides in same LAN within same rack

Whenever I try to log-in, I, without no specific reason ,automatically been logged-out.
To whom it concerned.
Good morning, I'm Bohyeon Kim from South Korea. I've been really appreciating your company's CC service which is like super excellent.
But, for a couple of days lately, i've been having this problem like shown above. Whenever I try to log-in, I, without no specific reason ,automatically been logged-out. Strangely, I have no problems at all using CC products (like Illustrator) though. Plus, I've paid every single fee for monthly plan perfectly well.
I hope this problem will be fixed as soon as possible, since I have to use CC like everyday for my business.Sign Out When Sign In http://forums.adobe.com/thread/1450581?tstart=0 may help

Manually Gap Detection & Resolution
Hello,
1) For manually resolving a gap, which one is the recommended method?
-By using RMAN incremental backup Or
-By manually copying missing archived files to the standby and register them with Standby
2) For Gap Detection and Resolution, does Oracle use both Automatic Gap Resolution & Fal Gap Resolution simultaneously or one after the other?
Thanks1) For manually resolving a gap, which one is the recommended method?
-By using RMAN incremental backup Or
-By manually copying missing archived files to the standby and register them with StandbyIf you have archives on primary then still i strongly recommend to troubleshoot and resolve the issue, If suppose the archives are transported and those archives are
deleted on standby from OS then again catalog those archives with standby. So that you can start recovery.
You can go for incremental rollforward, if in case you do not have any archives on primary or standby and no backups of archives available, But you have some more manual steps, you can check in detail from below link
http://www.oracle-ckpt.com/rman-incremental-backups-to-roll-forward-a-physical-standby-database-2/
2) For Gap Detection and Resolution, does Oracle use both Automatic Gap Resolution & Fal Gap Resolution simultaneously or one after the other?it will do automatically, initially detection will happen so that it analyze what the High and Low sequence/SCN need to recovery of course you can check from v$archive_gap, Based on that it will fetch the archives from the primary to resolve the GAP.
HTH.
