I know the uses of ORAPWD utility and REMOTE_LOGIN_PASSWORDFILE initialization parameter.I wish to know that, what will be the primary purpose of using ORAPWD passwordfile in the following situations.
1. RMAN Cloning.
2. Dataguard Standby configuration.
In DR site. i have to clone the database from pshysical standby database and clone db will be normal db not standby. Is it possible to do rman duplicate from active dataguard? will it support the duplicate database from active database or i have to take the rman backup of standby database and duplicate from backup piece.

In addition, how do I get a "user" in the password file when orapwd accepts file, password and entries as paramaters. Does this mean I need to give user "sys" sysdba privs?

Which makes sense to me as my understanding of this is that the log is written, send to the standby, applied, then applied on the primary, yes?
So my questions are:
Why is there a lower entry on the primary (234) marked as opening, when it's closing 235, and writing 236, what does LNS mean?
Why is the second archive on the standby saying "CONNECTED 0" and do RFS, & MPR0 mean?
My init files say this:
Primary:
log_archive_dest_1='LOCATION=/u01/archive/prod/arch'
log_archive_dest_2='SERVICE=prod_stby LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=prod_stby'
Standby:

log_archive_dest_2='SERVICE=prod LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=prod'

I've got a physical standby database and I'm now licensed for Active DataGuard. I would like to automate the ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION command to be executed right after the STARTUP command so that whenever the database is started by our DBSTART script, it activates READ ONLY W/APPLY immediately after start without manual intervention. This is probably simple, but I figured I'd ask before starting to pore through documentation.....!
View 6 Replies View RelatedWhat is the purpose of Standby Redo Log Files in Data Guard configuration? When it is utilized by the database?
View 4 Replies View RelatedWe have a 10g environment with DataGuard running for reporting purposes. Our application team is getting ready to upgrade their application and it requires that several SQL Scripts be run to perform the primary database updates. A couple of them are over 1 MB in length. My concern is that these scripts will break DataGuard. I am not a DBA by any stretch, but I seem to remember there are certain limitations with DataGuard.
I have reached back to the team and asked them to have the Vendor confirm these scripts are validated for a DataGuard environment and I have also reached out to the System DBAs for review. I am wondering if there is an utiility available that can check the SQL to confirm if there are any DDL or DML statements that will not work in DataGuard. Likewise, we are going to run these scripts in a non-production DataGuard enabled environment first, but I want to have some level of confidence, that this will be a success.
I have a dataguard setup, a primary and a standby.my instance is testdb.i have set all necessary dataguard parameters and everything seemed to work well initially with logs being moved from primary to secondary and being applied there.but all of a sudden i see that the primary pushes logs to the standby and at the standby end these logs are available but not applied.
when i try to execute the: alter database recover managed standby database cancel; it hangs for a long time and never returns to sql prompt.
i bascially want to stop and restart the MRP process to apply the logs but cannot cancel the managed recover mode.Is it advisable to kill the mrp process at os level using "kill -9 "?
Refer a MOS Note for configuring data-guard on Exadata with DR server being and Exadata DBM too.

We have a non-production Oracle 10g Cluster running on Linux, with DataGuard (logical standby). From time to time, we need to refresh the schema on primary, but to do so as always caused problems with the logical standby. Our DBAs can never get it to complete successfully. They have tried a bunch of different methods (even provided from Oracle), but it does not work. e have a bunch of skip statements on the
Everytime, we need to refresh the schema, we have to build the entire database (primary and logical standby) from production RMAN backup. As you can imagine this is a very time consuming ordeal. There has got to be a way this process can be completed in a timely manner.
I was thinking of the following....
1) shut down dataguard, log shipping
2) lock user, kill sessions, drop user from primary
3) lock user, kill sessions, drop user from logical standby
4) run impdb on production export file on primary
5) run impdb on production export file on logical standby
6) re-enable dataguard, log shipping
7) confirm logs being applied, databases in sync
We are only replicating the one schema to the logical standby. I am not clear on how redo logs would be applied to the logical standby. There are hundreds of them @ 100 mb each, so I would think if we do this independently, I could somehow sync primary and logical standby after the imports complete.
1) The Primary Database is UP. The Physical Stand By Database is DOWN. The Current Archive Log Sequence is 99 in Primary.
We have to apply Archive Log from 51 to 99 to the Standby Database. But Unfortunately, there is no backup of those Archivelogs and the ArchiveLogs from 51 to 98 have got deleted at Primary end.
Now how will you apply these Archive Logs from Primary Database to Physical Standby Database?
Note : The Physical StandBy Database is DOWN.
We have to configure Dataguard for our 24x7 critical banking 2 Node RAC database(10.2.0.4). Before proceeding with the configuration we have to make sure what steps we should follow to have minimum or no downtime.
1) Document covering DG setup in RAC environment.
2) We have to perform switchover as well so need its steps too. Either the normal switchover steps would be used or have to stop/start rac services as well.
we are running oracle database 11.2.0.3 and tomcat on the same machine(SLES 11).
I need to contol tomcat(start/stop) depending to database status. For example, if database stops or become standby then to stop tomcat service.
i have configured physical standby in my local system, to check logshipping i created a table at primary db, wen i tried to check in standby, it says table does not exist..below are primary & standby alert entries..

Given facts:
rman is used to backup database A to disk
rman is used to put those disk backups to tape
rman is used to duplicate database A to database B on another host
the duplicate process worked fine before we started testing encryption
the duplicate process worked fine with database A having an encrypted column in one table in a non-encrypted tablespace
Now, database A has an encrypted tablespace with nothing currently in it. The duplicate process now ultimately fails with ORA-19913, unable to decrypt backup.
I am not using encrypted backups, not specifying encrypt or decrypt anywhere in the duplication process. The only thing that is encrypted is the one tablespace in database A. I have the same wallet files on Host A (database A) and Host B (database B). Wallets are open. So why does the duplication process fail because the backup cannot be decrypted?

This My backup policy and retention
I have monthly full database backup on march the backup started 2nd march 15:31 and completed at 03 march 11:12 AM retention period 3 years
We have ADHOC ARCHIVE backup which will run for certain conditions if the file system threshold reach 80%
In between the monthly backup the ADHOC ARCHIVE jobs has executed from 03Mar2011 00:00 to 03Mar2011 05:14 this retention period is 30 days
So while restore the database with monthly backup i can't able to recover the the datafiles due to adhoc archive files are missing.
We are cloning a database, but using the restore method ( version 11.1.0.7). The source and destination path are different. As we are using the source controlfile, before restoration SET new name inside the run block is the way to change the path.
I was just wondering, if there is any other way to do it. Because, we have around 1000 datafiles, and dont want write everything in the run block. Also, this goes from Non-ASM to ASM. I tried DB_FILE_NAME_CONVERT, but it seems to be not working.
run
{
Set newname for datafile 1 to '+DATA_DG1';
Set newname for datafile 2 to '+DATA_DG1';
Set newname for datafile 3 to '+DATA_DG1';
Set newname for datafile 4 to '+DATA_DG1';
restore database;
switch datafile all;
}

You could say that what I'm trying to achieve is analogous to a flashback, but rather than specifying a timestamp, I'd like to simply restore the entire db to exactly what was there when the tagged backup was taken.Here is the RMAN script I am using for the backup procedure:

I'd like to take these backups in online mode, and I've tried taking both a consistent and inconsistent backup modifying the above script.Additionally, I'm using the following restore script to try to revert the database to the state when the backup set was taken (and am testing the data being restored by deleting some data entries after taking the backup):
run {
#shutdown db (should be done already)
SHUTDOWN IMMEDIATE;
#mount db
STARTUP NOMOUNT;
#show RMAN settings

When performing the restore, I dont see the data backed up, rather I see the latest data still in the database. why the state of the db is not getting reverted to the backupset with tag='latest'.Finally, here below I've listed the rman settings for reference:
