Data Guard :: Broker Connecting To Standby Database Fails?
Jun 4, 2013
I checked lots of pages but I'm not able to find a solution für my problem. I already set up a primary and a standby database (prim = ALPHA1 / standby = ALPHA2). After enabling my dgmgrl configuration I got two errors:
DGM-17016: failed to retrieve status for database "alpha2"
ORA-16664: unable to receive the result from a database
The dg log from ALPHA1 says:
06/04/2013 16:06:57
Site alpha2 returned ORA-16664.
Data Guard Broker Status Summary:
Type Name Severity Status
Configuration alphadgb Warning ORA-16607
Primary Database alpha1 Success ORA-00000
Physical Standby Database alpha2 Error ORA-16664
While the dg log from ALPHA2 (standby) says:
06/04/2013 16:43:28
SPFILE is missing value for property 'LogArchiveFormat' with sid='ALPHA2'
Warning: Property 'LogArchiveFormat' has inconsistent values:METADATA='arch_ALPHA2_%S_%t_%r.arc', SPFILE='(missing)', DATABASE='arch_ALPHA2_%S_%t_%r.arc'
Failed to connect to remote database alpha1. Error is ORA-12514
Failed to send message to site alpha1. Error code is ORA-12514.
How can I solve this issue? Every type of tnsping is successfull. The sqlplus login from the primary to the standby database works, the other way round works too! Therefore the tnsnames and listener data seems to be correct.
My configuration for ALPHA1 (primary db):

create another standby database on a new server.
I'm running Oracle 11.2 EE on Solaris 10.
We already have one standby database, but now, I want to create another standby database on another server, which ultimately I will make primary and then replace and destroy our current primary/standby databases.
Also, just for the heck of it, I tried to look in our DB Console, and the "Add standby database" is grey'd out.
Is this because I am only using DB Console, and not Grid?But if that were the case, why would the option even be in DB Console, or perhaps is there a lmiitation to the number of standby databases you can manage with DB Console?

I got a primary database which ships logs successfully to a standby database where it is applied successfully as well.
I can connect using the tns name defined for data guard (which are already used for log shipping) in sqlplus.
Yet, at the time of configuring data guard broker,the command add database 'standby' connect identifier is 'to_standby'; fails.
Looking into drc<instance>.log, I see the error ora-03113 network I/O.
I haven't seen any error like that online and I can't explain why it does that when logs can ship already with the same connection identifier.
I have edited dest_2 with and without parameters LGWR and SYNC and reconfigured the broker without success. I've removed the configuration files and tried again.
I've checked that the password file is the same on both servers as well.Nothing seems to work. Is there a parameter I'm missing somewhere.

I have dataguard configuration operating in maximum availability mode with a local standby db (A - lgwr sync not using real time apply) and a remote standby db (B - lgwr async). I then simualted a crash of my primary database with batch jobs running. Since the stby db A is in lgwr sync option ,all the commited data in the current online redo log has been transmitted to stby A and is present in its stby redo log (Group 2).How do I apply this stby redo log to the remote stby db.
Tried the following methods.
1.ftp the stby redo log to the remote db and tried to regiter it, got an error that it is not completely archived.
2.issued the recover standby database command and supplied the stby redo log when it asked for the sequence in the stby redo, got an error saying there is corruption in a block(tried this option multiple times ended up with the same result.)

Controlling User Access to Tables in a Logical Standby Database can be controlled using the following command:
ALTER DATABASE GUARD STANDBY;
My simple question is: how can I know the current active Guard setting in the standby database?

I am fairly new to Oracle and have recently started learning the basics of Data Guard. I have set-up a Primary 11g database which successfully ships and applies logs to a Single Standby (on the same server) as expected. Manual switchovers work fine; however, I have found a slight problem when performing switchovers using the Data Guard Broker utility.
The switchover is successful- but the broker cannot restart the Primary instance. The strange thing is that when I perform a switchover in the opposite direction (i.e. the new Primary goes back to standby again) it works fine. The error is receive is: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
The majority of posts I have seen on this topic seem to point to incorrect listener / tnsnames set up but they have exactly the same values. If both databases are identical, why does it work one way but not the other? I will provide any necessary files to pinpoint where the issue could be.

I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site

I have set up a single instance standbys for rac databases. Now, I need to offload the backups from the primary on to the standbys.
1. cancel managed recovery
2. connect to target(standby) and catalog and backup the standby
3. put standby in managed recovery mode.
I think following these steps, I can restore primary(?). Now, My question is, how can I use these standby backups to clone/refresh databases? I tried it by connecting to target(primary), catalog and auxiliary but rman is using the primary backups instead of standby's to refresh the auxiliary database.

i have done oracle data guard between two databases (database A is the primary) and (database B is the standby), and it was working fine for two weeks, then the network admin did some changes on the firewall on standby side, which made the primary database can not write on standby redo log , so archives was generated on primary and do not generated on standby by, now we solve the firewall probelm and new archives generated on primary is generated on atandby too, but now i have a gap in archives on standby database and standby database now is not synchronized with primary database, and data changes happen on primary is not reflected on standby, also archives that were generated on primary and did not generated on standby during the problem time is not registered in V$ARCHIVED_LOG neither on primary database nor on standby database
