Monitoring Data Guard with SNMP?

I have configured Data Guard within two Oracle environments and have written a small Perl script which monitors the applied log service and sends an email if something fails to be applied.
I am assuming this is not the most efficient way of monitoring the systems and would like to use SNMP.
Can anyone tell me if it is possible to monitor Data Guard using SNMP (traps)? If so would you know what documents are available?
Cheers!

RMAN in active data guard with real time apply ON without a catalog DB

I would like to know whether I can take RMAN backups (both level 0 & incremental) in active data guard with real time apply ON without a catalog database. version is 11.2.0.3.2. Will it make difference in the control file of standby syncing with primary? Can I use these backups on primary to restore and recover the database(including control file backup)?

Thank you very much msberg. Could you please answer the below queries as well?
Should I cancel Real Time Apply before starting RMAN?
Will it make difference in the control file of standby syncing with primary? Is it possible to use these backups on primary to restore and recover the database(including control file backup)? If possible, how will I do that?

Using OEM to monitor Data Guard database

Can someone please send me the link or docs of how to use OEM monitoring data guard? In specific, I would like to use OEM to monitor and be sure logs are applying to stand by site.
Any ideas?

Hello ,
I will extend the document on the Fast Failover feature one of these days.
What you need to do is:
For using Fast Failover, you need to configure the Data Guard observer process.
The configuration of this process can be done by selecting the Fast-Start Failover Disabled link on the Data Guard page of the database (Primary or Standby).
You will be automatically redirected to the Fast-Start Failover: Configure Page.
From this page you can do the configuration of the DG observer process, that then will enable you to activate the Fast Failover feature.

Data Guard with Oracle 9i and 10g -- have you done it?

We have an ERP system (JDEdwards, db size approx 600 GB) and we'd like to copy the data in this system to a database on another computer. We'd use the remote database for reporting, so we need it to be available. We are looking at using Data Guard running in Logical Standby mode.
The ERP database is Oracle 9i, and we are considering having the Logical Standby database be 10g. Have you done this and if so, what was your experience?
Here's why we want to do this. There are many tables in the ERP database that contain descending indexes. We can't change this, and it is not supported with Data Guard under Oracle 9.2. Tables with descending indexes do not copy to the logical standby database.
We were told that this is corrected in a newer release of Oracle, and we were wondering if a 10g database would properly copy tables with descending indexes.
Thanks in advance for any experiences you can share.
Best Regards,
Mike

What you are trying to do might not be possible. Because when you create logical standby you have to create a physical standby first and convert it. Primary and standby have to be same version.
In furture it might be possible because 10G will support rolling upgrade of logical standby.
However even it's possible you have to go through a lot of pain to setup and maintain it because Oracle don't support the setup.
What you could try are Stream and Replication, I will say Stream is very interesting one. Because Oracle say : "Oracle Streams and Oracle Data Guard (including Data Guard SQL Apply) are independent features based on some common underlying infrastructure and technology. "

Oracle8i Data Guard with log shipping

Is it true that :
in Oralce8i, with the data guard, there will be zero data loss if online redologs have been mirrored in DR site and in the event of DR, the last un-finished redolog can be used to recover the database.
What product is used to apply the redolog ?
I know Oracle9i claim this is possible, but when will Oracle9i available to Sun platform ?

Yes, that's correct. As soon as you leave the restore session, you have to provide a 'overlap' of log information so that the recovery can continue.
> 2. Can't I mix the restoring of incremental and log backups in this way: log001, incremental data, log002, ...? In my tests I was able to restore the incremental data direct after the complete data, but not between the log backups.
No, that's not possible. After you've recovered some log-information the incremental backup cannot be appliead as a "delta" to the data are anymore as the data area has already changed.
> 3. Can I avoid the state change to OFFLINE after a log restore?
Of course - don't use recover_cancel
As soon as you stop the recovery, the database is stopped - no way around this.
There are some 3rd party tools available for this, like LIBELLE.

Steps for Data Guard with one primary and 2 standby

Hi,
Database :10.2.0.4, 11.2.0.1
Os: Windows , Unix
A ----------------> Primary database
B ----------------> Standby Database 1
C ----------------> Standby Database 2
I want to configure *2 standby* databases for single primary database.
Lets take, A ,B and C are my machines.My data guard configuration will be like,*archive logs will be moving* from A to B and A to C.
If i do any switchover in between A and B , now B is primary and remaining A and C are standby databases.At this stage also , archive logs should move from B to A and B to C. Also, same should happen from C to A and C to B,If i do switchover in between B and C.If everything is fine , then i will do switchback to main Primary database(A).
How do i have to mention PFILE in all machines ,the parameters like
LOG_ARCHIVE_DEST_1=LOCATION=<PATH> -- LOCAL ARCHIVE PATH
LOG_ARCHIVE_DEST_2=SERVICE=
LOG_ARCHIVE_DEST_3=SERVICE=
FAL_SERVER=
FAL_CLIENT=
STANDBY_FILE_MANAGEMENT=
In my tnsnames.ora , primary,standby1 and standby2 are my service entries and these are same in all of my machines.
Please suggest me , how do i can configure my pfiles in all machines ?.
Thanks,
Sunand

Parameters need to configure Data Guard with Data Guard Broker

Hi gurus,
I'm following this guide http://www.oracle.com/us/solutions/sap/wp-ora4sap-dataguard11g-303811.pdf, but it isn't clarify what parameters we need to set to get the service up.
I noticed that we can setting up for two ways, either Oracle Enterprise Manager or Data Guard Broker. Do we need to configure the same parameters to OEM and after to activate the DGMGRL?
Can you help me?

Monitoring DHCP leases with SNMP

Hi,
is there a way to monitor the number of DHCP leases (show ip dhcp binding) of a DHCP pool created on a 2960 switch?
Regards, Leonardo

Once I got my SNMP host to accept the correct attribute and configure the event trap all I had to do was add the trap command to the router. I then bounced one of my low usage PRI's (which had 0 calls on it ) and got the following event traps on the SNMP host:

It doesn't tell you specifically which interface is down but at least it narrows it down to the gateway/router. Most of our gateways have only one PRI anyway.
We use Spectrum One Click for network monitoring.

Is this the best way:

or are there some other traps that I can enable?

Hi Guys,
I am looking for a shell script that i can cron ,which monitors dataguard env (10g and 11g )and sent email alerts if DR go out of sync say by 10 or 15 logs
i found couple on the net but not working for some reason
http://emrebaransel.blogspot.com/2009/07/shell-script-to-check-dataguard-status.html
if you guys have some please share

You are using an advanced version of Oracle and want to plug an obsolete script into it??
Why not just monitor the Data Guard with EM or Grid Control and setup emails in there? It is 100% more reliable than anything else.

9i RAC to single standby DB with Data guard

hello gurus,
I have a question, Im trying to set up a standby database.
The primary DB would be a two node 9i RAC R2, to a one single standby DB.
I done this already. My question is if I can use data guard with this type of configuration. I have try to configured it with OEM and the GUI does not support this.
does any one know if this can be achieve using dataguard's CLI??
thanks

well that is something out of my reach for the moment.
I have to do everything on 9i.
I have the standby environment running already, i just want to make my life easier trying to ad min this environment using data guard
