Ifiles DataGuard
Hi all
EBS 11i
9i
RHEL5
I'm configuration dataguard for ebs 11i with Doc 216212.1
In Section 3: physical Standby Ridge - point 2: configuration Oracle Net communications to and from the standby.
The task is to create a <CONTEXT_NAME>_ifile.ora
. and listener_ifile.ora.
These files are required? I check from its parent listener.ora and tnsnames.ora files and I see that thay are just redundant?
Their content also exist in the parent file?
Please enlighten if I need these files.
Thank you very much
JC
Hello
Because they are many DBA worldwide and with different standard environment maintained (custom) for them, so in order to solve the complexity (or instead of change/complicate things), they give flexibility as inputs plug-in and plug-out to file (with ifile as subset). So that they can add or just throw will be a comment in tnsnames.ora based switch above and switch back.

What you have shown here is the log_archive_dest_2 of the primary database. You must clear the log_archive_dest_2 of the standby database too.
The error is speaking on the parameter log_archive_dest_2 of the database pending. 12 c, then the broker configuration, you must clear the log_archive_dest_2 (destinations archive remote) on the primary and standby databases. DG broker would take care of her.
On autonomy in standby:
SQL > alter system set log_archive_dest_2 = ";
And then try to add the standby database to the broker configuration.

Small questions about Dataguard
Hello
I have a few questions about Dataguard. I'm new to DG, carry me so for the display of these fundamental questions:
We plan to install Oracle 12 c to Win 2012 R2 with primary and physical intelligence on different physical servers. We are looking for HA solution, but cannot afford to license CARS. The two primary & Eve are going to be in the same data center connected via a 1 gigabit network. So I have a few questions related to it.
(a) since both of our primary & Eve is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.
(b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?
(c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?
(d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?
(e) I was reading about the modes of Protection, account required to our current situation & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.
(f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.
Concerning
Learner
(a) since both of our main & secondary is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.
Well it will not provide the level of HA that is RAC. RAC is a Transparent Application failover. With a physical standby, you need to apply some delay for a failover operation. You can implement the observer that can automate the failover and reduce the time.
(b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?
This isn't really the DG broker, but rather the observer you will need to implement. The DG broker automate failover. It will be the observer who "sees" (where its name) that the principal is down and initiate the failover process. To do this, the observer will use the DG broker, so it will be necessary.
(c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?
You'll want to read on the QuickStart failover. http://www.Oracle.com/technetwork/articles/smiley-fsfo-084973.html
(d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?
The DG broker is required to run on the database server. The DG broker will run on the primary and standby. I think that what you're asking really anything is if the observer can run on a PC. Yes it can. However, it is probably not a good idea. A PC will not have the internal hardware redundancy, a server can have. If the PC can fail more often than to a server. And if the gods are bad, it will fail when you most need.
(e) I was reading about the modes of Protection, account required to our current scenario & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.
Your choice should depend on the amount of data loss is acceptable.
(f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.
Oracle integrated security only works on Windows with a MS Failover Cluster. Real DBAs do not have Oracle on MSFC.
See you soon,.

Problem is fixed - value StaticConnectIdentifier checked to a database of primary and standby in dgmgrl ==> primary port and standby was wrong wrt to the listening port value.

Hi all
I nam using Oracle 11 g on RHEL 5 2.
I had implemented the DataGuard (database physical Standby).
I just want to know in case of failover, my Eve becomes primary, and after some time my first back, how will I do that primary to new standby/primary.
I mean, that is, after the failover if the failed node comes up, what is the best way to do is tandby again.
I'll reconfigure the dataguard setup?
Kind regards.
This reinstante can be so configured DGMGRL, right?
If the broker is configured, the reinstatement may be made.
If the broker is not configured, then you have to flashback to the "old primary" database to the value "Eve became primary YVERT" and then convert pending database. (Please note that you must have active flashbacks).
Please see the I posted in my previous answer. Which don't use a broker.

How to apply the patch to power supply in an environment of dataguard
I need to apply a patch of power supply in an environment of dataguard. I would like to know the sequence of steps I must follow.
Can someone please help me on this? DB version is 11.2.0.4 and I need to apply 11.2.0.4.3 PSU.
In order to apply the fix, you must first carefully read the "Readme" of the patch for instructions.
To give an overview of the sequence of steps to follow to apply a patch in environment dataguard, here it is:
1 reporter on the primary to the standby log shipping.
2 cancel the MRP on the standby database.
3. apply the patch of power supply on the standby server. -See the Readme for instructions.
4. ensure that the standby db is mounted and the earpiece is in place on the standby server.
5. do not run any script correction on the standby database.
6. apply the patch of power supply on the principal server.
7. make sure that your primary database and the listener on the primary server is running.
8 turn on the primary to the standby log shipping.
9 start the MRP on the standby database.
10. run the script of correction (catbundle.sql) on the primary database and monitor the progress of the eve of the resumption.
Please refer to this

Hi all
I want to have dataguard with cars at two knots in physical configuration and standby.
For this I have question how archives will be transmillted from the primary to physics.
This means that the head node 1 will on node1 Eve and similarly for node 2 archives or all primary archives will be forwarded to node 1.
Kind regards.
It is understood that if any node on sby descends to archive two primary nodes will keep to be shipped on an active node of SBY (only MRP should be active on THST)... good?
Yes, if MRP is not running on the active node of the standby, then you must manually start the MRP.
If she is correct understanding, then I have only one doubt that we all configuration setting or a parameter for this archives begin is transmitting on the active node on SBY or oracle manages automatically?
No, you don't have to make any changes.
Reason: on the database principal, you set the log_archive_dest_2 (or any remote dest parameter to ship again to wait), you would use the "service =
'.»» This alias would have the "scan name" Eve and all the nodes of the standby registered the listener to scan that you can be aware of. So even if 1 the standby node goes down, primary will always be able to ship the remake on the eve and the node is active on the eve will receive them and apply.
For example:
On the primary:
The log_archive_dest_2 looks like:
Service string LOG_ARCHIVE_DEST_2 = "srpstb", ASYNC NOAFFI
Optional delay of RM = 0 compressio
n = disable max_failure = 0 max_co
nnections = 1 reopen = 300 db_uniq
ue_name = "srpstb" net_timeout = 3
valid_for 0, =(online_logfile,a)
ll_roles)
NET watch alias name looks like this:
SRPSTB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = ora12cdr-scan)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = srpstb)
)
)

As I mentioned, again the DG transport and apply the will to work in mixed versions. But it is not supported by Oracle for longer period. When I say not supported which means lets say if you hit any bugs in mixed environment associated with DG, then you can't get a support to connect to a new bug... etc... However, mixed versions are supported bby Oralce for 30 days. This is because any time the migration/upgrade that you can keep primary and standby in different versions.

Speed of transfer network for dataguard
Hi all

RHEL6
I'll put up dataguard PROD at the DR site.
What is the network speed required between servers in site/two for dataguard?
Is enough 1 MB/s?
Thank you very much
JC
You may consider setting up to use a time based on check-in. In order to keep the size of 1 G, but the archive size is just what data is there when the archive is created. It's much smaller than I'm used to it, so apologies for that. See the init parameter archive_lag_target. There are, of course, to many ways to set up DG.
ALS is a document that defines (among other things) the speed at which you can recover. 15 or 20 minutes is often suggested for when companies are unable to arrive at a precise definition. So every 15 minutes, the db spits out a newspaper, DG move more and the applied. Some deliberately put places in a lag time too much, then you can "pull the plug" If you know someone has screwed up bigtime, without having to make a recovery. You also must define exactly how you will apply newspapers (there are a number of options, make sure that you understand the concepts) and expectations for the digital switchover and how to deal with the app and substitution.
