How to find the server is whether standby (slave) or primary(master) in Postgresql replication ?

-
Method 1 You can check the mode of the server using "pg_controldata". [pgsql@test~]$ pg_controldata /usr/local/pgsql/data84/ Database cluster state: in archive recovery --> This is Standby Database Database cluster state: in production --> This is Production Database [Master] Method 2 You can use pg_is_in_recovery() which returns True if recovery is still in progress(so the server is running in standby mode or slave) postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- t (1 row) If Return    false   so the server is running in primary mode or master postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- f (1 row)

rman interview and scenario based questions and answer and also rman(backup and recovery) discussions panel

set 1 1.What is RMAN? Recovery Manager (RMAN) is a utility that can manage your entire Oracle backup and recovery activities. 2.What is the difference between using recovery catalog and control file?  When new incarnation happens, the old backup information in control file will be lost.

If you don’t already have VirtualBox,  download it here for your platform of choice . Once you are configured, we will be all set to get started. Creating your RHEL VM in VirtualBox The steps are pretty simple. We need to start by creating our new machine. Set the OS type as Linux, and choose Red Hat 64-bit for the version: Next, we choose the memory. For speedier response, let’s pick 2GB (aka 2048 MB) for our memory: Next, we choose to create a new disk: Select VDI as the disk type: Choose dynamically allocated as the growth method: We want a little bit of play room, so make the disk 20 GB. Because it’s dynamic, it will only use disk space as it actually gets filled, so you should be ok as long as you have room locally: Now we have the new VM ready to start with, so click the green Start arrow and let’s build our server: The VM will complain about having nothing on the disk, so just let that error sit and click the little CD icon on the bottom...
