in a RAC multi-node environment with single instance dataguard..Recovery is not running automatically I have to re-run the recovery command to make them sync and this command works for already archived log files no upcoming archive log file applied I have to re-run the recovery command again for newly archived log files.
View 2 RepliesPrimary RAC and Standby RAC databases are using version 10.2.0.4. They are configured & controlled via Data Guard Broker. Currently, the observer runs from one of the Standby nodes. All are on Solaris x86 64bit OS version 10.
Now, I have to move Observer to 3rd DC and I am looking If I could use another OS for observer instead of same as DB OS version. Why? Our new infrastructure is on RHEL Linux, therefore, I would like to deploy observer once and then wait for existing databases to be upgraded and moved to RHEL. Also, i understand that database and observer software should be of same version e.g. 10g, 11g.
My question is what if i install & configure observer on RHEL ? The end result would be:
1. Primary DB: Solaris 10, Oracle Software binaries version 10.2.0.4
2. Secondary/Standby DB: Solaris 10, Oracle Software binaries version 10.2.0.4
3. Observer: RHEL 5.8, Oracle Software binaries version 10.2.0.4
Is it accepted mix configuration say e.g. to run for six months? Also, it would be grateful to know if there any license implications when running observer on a different node running no databases at all.
I new to data guard concept.
I am using oracle 10g with data guard configured , I have primary ( A ) and standby database ( B ) .But because of some unavoidable conditions the primary database ( A ) got shutdown and was not starting , We shifted the standby database ( B ) at new location and changed it to primary with following command ,
startup mount;
alter database recover managed standby database finish;
alter database commit to switchover to physical primary;
shutdown;
startup;
This new primary ( B ) was open for end users for 2 days during which old primary ( A ) was shutdown .
I took the backup of ( B ) and restored it on A AND shutdown the B . Now A is acting as Primary database. Server B is shutdown . I want to change server B to standby database with A running as Primary .Is it possible ?
I have a SAN systems with primary and secondary interfaces. i need to know what is best practice of oracle to use disaster recovery features, with automatic or manual failover concept.
example.
Primary Server Duty Station 1 New York
Secondary Server Duty Station 2 Los Angelous
requirement : If primary server in DS 1 gets fire and completed get down then secondary server DS 2 should become primary server and reply to client request with AUTO or Manual failover concept.
I have done the configs as per the guide here [URL] .... This is a physical standby db

How I do I make sure that the DR site is recovering automatically ?
My standby database was working fine which was running in maximum performance mode .Suddenly i found that logs are not being applied though archived logs are received from primary database.i issued the command in mount mode: alter database recover managed standby database disconnect from session;
altered database this command runs successfully. but MRP process in not initiated which i confirmed with the query (select process,status from v$managed_standby;)
i have done oracle data guard between two databases (database A is the primary) and (database B is the standby), and it was working fine for two weeks, then the network admin did some changes on the firewall on standby side, which made the primary database can not write on standby redo log , so archives was generated on primary and do not generated on standby by, now we solve the firewall probelm and new archives generated on primary is generated on atandby too, but now i have a gap in archives on standby database and standby database now is not synchronized with primary database, and data changes happen on primary is not reflected on standby, also archives that were generated on primary and did not generated on standby during the problem time is not registered in V$ARCHIVED_LOG neither on primary database nor on standby database

I have created dataguard between two instances hosted in two different servers. I have done switchover from primary to standby & then again standby to primary with DGMGRL utility.
1- When I done switchover to primary & trying to open standby database in readonly mode it was giving below error-
ORA-01154: database busy. Open, close, mount, and dismount not allowed now
Why this error was coming ?
2- As I was not able to open standby database in read only mode, I have executed below command-
alter database recover managed standby database disconnect from session;
which return an error as-
ORA-01153: an incompatible media recovery is active
After this I have executed-
alter database recover managed standby database cancel;
which executed successfully.
& then after standby database open in read only mode.
Why above error was coming ?
3- After this I had tried to check the checkpoint_change# & controlfile_change# from primary database and result shows both number were different.
Why they are not matching ?

We have an Oracle application 12.1.1 running with oracle database 10.2.0.4 and we're using HP-UX itanium 11i v3 servers for both application and database, our requirement is to establish a Disaster Recovery site out of our building to ensure data protection.
What is the best option we can use to reduce the cost and to implement the DR site? can we use data guard ? and will be the configurations and requirements for it?

Quote:
To change the standby database from being open for read-only access to performing Redo Apply:
Terminate all active user sessions on the standby database. Restart Redo Apply. To start Redo Apply, issue the following statement:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> DISCONNECT FROM SESSION;
To enable real-time apply, include the USING CURRENT LOGFILE clause:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> USING CURRENT LOGFILE;
this is what happen
SYS@ngdr> alter database recover managed standby database disconnect session;
alter database recover managed standby database disconnect session

ERROR at line 1:
ORA-00274: illegal recovery option SESSION

okay since I encountered the illegal recovery options session, I decided to use alter database recover managed standby database using current logfile; now the session seems to be hanging forever.

However, for my practice, I need to estimate archived logs size before backup them, so I need to stop archive log for a while and enable it later during DB running.
I check Oracle documents, it only mentions changing archive log mode at DB mounted but not open.
We are using OCI call library to connect to Oracle database through one application. When we try to run this application through valgrind( a memory leak detection tool for linux) then, OCIServerAttach() call is failing to connect to db and it says that "ORA-1034 :Oracle not available"," Oracle instance may be down", etc. However, our oracle instance is running and database is open. When we run our application normally ( not through the tool) then everything is working fine.

Why there could sudden spike of demand on UNDO data in Active Data Guard ?
I am working in a bank as an system consultant, i have a SAN Storage Area and oracle as below.
SAN 1
This interface includes the DATA FILES of the oracle tablespace
SAN 2
SAN1 Mirrors the DATA FILES of the oracle tablespace to SAN 2
1. Can i rely on real time data recovery from SAN2 ?
2. if SAN1 (Data Files are currupted) will the SAN2 Data Files will be currupted as well.
3. If the SAN2 is currupted then what Oracle Features can be used to have uncurrupted data.
