1/47

Creating an Oracle 11g Dataguard on VWware

using rman "duplicate target database for standby

from active database"

I created a VMware Linux Redhat 5.3 server using the Unbreakable Linix distribution provided by racle.In this exercise I will use the server ha! as "aster and the server ha# as standby

$he beauty of this exercise is that I a" going to use the new 11g command %duplicate target database &orstandby &ro" active database%. $his co""and creates a standby database &ro" an active database on the &ly.

In previous releases the '() had to take a backup o& the "aster* copy it over onto the standby site and restoreit. (y using %duplicate target database &or standby &ro" active database% no ad interi" backup is needed* thedata&iles are directly copied over.

Create an 11g database to start with

$o start with* the racle !!g so&tware will be installed choosing only the re+uired co"ponents and a databasecreated &ro" the ,UI

3/47

I will leave out co"ponents that are not necessary


4/47

-aving "oved the VMware nodes around* I &orgot to check the status o& the network and a result the errorR)!#!5/ occurred.


5/47

$he reason &or the error R)!#!5/ was that the network was down0 it is better &or everybody that it is up.


6/47

Configuring the database as a master

$he &irst re+uire"ent is that the database is put in %1R2 L,,I4,% "ode.


7/47

I& you decide to run the data guard in "axi"u" protection or "axi"u" availability* the transaction are copiedover to the standby site by the log writer and are written to the standby log&iles0 this is why we create standbylog&iles that will be used not locally* but by the standby.

$he view V6$)4'(78L, contains in&or"ation about the standby redo logs.

)nother way o& checking the progress is* o& course* to create a user LL on the "aster database and his tablet8a* populate it and "ake sure that it gets propragated onto the standby.


26/47

)t this point we have a working data guard0 as the grid control is beco"ing "ore and "ore popular* I will

investigate how to "anage the data guard &ro" the console* as shown in next pages

F)'G

!anage a Data uard configuration with the rid

Control

1or this exercise I will be using the VMware Linux serversC grid!>g* which hosts the ,rid 2ontrol "anage"ent

server* ha!* where the "aster database in a data guard couple is running* and ha#* where the standby databasehas benn created. (oth ha! and ha# are con&igured with the grid control* both having a "anage"ent agent.


27/47


28/47

ur purpose is to couple the "aster database M)6$R1 on ha! with the standby database 6(1! on ha#

9e start setting up the data guard broker con&iguration using the grid control


29/47

9e expect that we will be able to choose 6(1!* and the screenshot o&&ers indeed this option

$his is an installation on a VMware Redhat 5.3 guest syste"0 the purpose o& this &ull exercise is using the gridcontrole to "anage the !!g 'ata ,uard con&iguration on two other VMware guest operating syste"s.

)s there is no grid repository available* I will choose to create a database* install the M6 and install the agenton "y virtual node grid1$g.

ven i& the M6 is local* an agent is needed. I will use the version !>.#.>.!.! to "ake "y li&e di&&icultJso"eti"es in our pro&ession as '() we are &aced by co"plex environe"entsK* and then upgrade to !>.#.>.5
