Apr 9, 20131) If i do changes in table on primary database and if i open standby database in Read-Only mode, i can see those changes immediately only if Real Time Apply is enabled. Am i correct? Database version is 10.2.0.4
2) From 11g, It is possible to apply redo while the standby is open in read only mode. prior to 11g, it was not possible. Right?
3) Should I first cancel Managed Recovery prior to issuing “ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY”?
RMAN :: Oracle Recovery Catalog Database In Primary And Standby Mode
Jul 9, 2013The customer wants the RMAN recovery catalog database to be highly available so that none of the RMAN database backup jobs are impacted at the time of taking the database backups. There are are 200+ databases running on OEL, RHEL and Windows. So we planned to host the recovery catalog database on Oracle Active DataGuard 11.2.0.1 Enterprise Edition on RedHat EL 5.8 version on two physical servers.
The Primary Instance will be in one server in the Primary DC and the Standby Instance will be on another server in another DC. Also all the database datafiles are hosted in ASM Diskgroups on SAN (DATA, FRA, REDO, ARCH diskgroups). Are there any specific RPM/patch/OS user custom/specific settings or configurations needed..?
Data Guard :: Apply Standby Redo Log To Physical Standby Database
May 26, 2013I 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.)

Data Guard :: ORA-00274 / Illegal Recovery Option SESSION Physical Standby DB
May 6, 2011oracle version: 10gr2
os:windows 32
I have configured a physical standby database.
I have set the physical standby database to open read mode for a short while.
according to [URL] in order to set db in for from open read-only to applying redo data
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
SYS@ngdr> alter database recover managed standby database using current logfile;
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.

Data Guard :: Apply Patches On Oracle Database With Logical Standby Database?
Apr 22, 2011I 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

Data Guard :: Backups On Physical Standby Database (RAC)?
Nov 23, 2011I 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.
