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?
Oracle 11g R2.

Our system administrator upgraded from apex 4.1 to 4.2 last night. This morning, we no longer have the dev-toolbar at the bottom of the page when I run a page from Application Builder. Not sure where to look to sort that out.

I have set up a cross platform (Microsoft Windows IA (32-bit) -> Linux x86 64-bit) data guard and it worked fine.Then I did a switch over (which again worked) and found out the data is not getting replicated at all.. checked the data files available from the new primary database and found out they are in the windows format as below..
SQL> select name from v$datafile;

I would like to know about oracle 12c. In 12c, when i read documents,i understood that one container DB(CDB) can contain upto 253 pluggable DB and this pluggable DB(PDB) is similar to our traditional database(pre 12c).
1) whether my existing database (11.2.0.3) can be upgraded as pluggable DB and plugged it in CDB?
2)i read that we can move from local data center model to cloud in this version. Is that mean that once PDB is ready, whether we can plug it in CDB using private cloud or public also possible?
3)If public cloud is possible, are both CDB and PDB accessed through cloud client only?If so, whether our user data that is available under PDB also moved to external place?

Our organization has recently decided to go for storage metro cluster solution for disaster recovery. In a Data guard environment, we normally calculate how much archive log is generating and based on that value we calculate the required bandwidth.
For storage metro cluster, we need to find how much block is changing in our primary database, and the same rate of change would apply on DR cluster. Now, i need to give the assumption how much changing is happening in my system. How to calculate the change.

I am very new to data guard...I have a primary and a physical standby database...If the primary got crashed, are the users directly switched to physical standyby (is it automated) or the DBA has to manually do the fail over or switch over....is it the same concept as in RAC like TAF....How can the DBA know that the users are disconnected from the database.....explain with some steps...
the version is 10.2.0...

Log shipping stopped logging/shipping into the Standby Database in one of our Oracle Data Guard Servers about two month ago and there was no change carried out as at that time. The Data Guard has only one Standby database. I have been managing the log shipping and recovery manually.

I am working on Data Guard concepts. I have configured Data Guard which is working fine.
Now I am trying to work on script which can give me output on OS prompt if there are any archive gaps..
I tried to use few commands on a script archgap.sh as

I have a Windows 2003 server with Oracle 10.2.03 database residing in one datacentre, with Dataguard configured to a physical standby in a similar location (proven process that works great).
I now have a requirement to transfer and synchronize the same live database to a database in a different country (AIX box), purely for data purposes not failover etc. I can transfer an export of the Database and have this up and running as a logical database of the live on AIX, but is it then possible to configure dataguard on the Windows server to also send updates to this logical database on the AIX system? Thus keeping them in sync with each other?

I have a RAC system with DR set-up, this is a test environment and it doesn't have any backup, why DR is required but it exist. Since this is a test a lot or archives gets generated and deleting the archives has become a daily job for this server manually.
I want have a script to delete archive logs which is in non-ASM (i.e. filesystem) after ensuring that the archive log has been applied in standby database. If this can done only by RMAN.

Application server server (2 server) -Solaris 10
Web server (2 server for Failover)= RHEL
For DR
Database (1 node)-Solaris 10
need to know
1.What are the best practice to implement and to configure DR as Non-RAC physical standby for RAC database server.
2.What are implication if we go for single node except failover node unavailability for DR.
3.What are the steps of Switchover in this case.
4.What's the recommended backup solution for 8-10 Terabyte database

[ START REDO APPLY USING REAL-TIME APPLY ]
SQL> alter database recover managed standby database using current logfile disconnect;
Which of the two commands should i use in my production database.
