Find information about dataguard
Hello,
I read the next note about dataguard
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239.pdf ,
then I have several questions.
- 1 - I do not understand which manage dataguard.
- is it brocker or OEM or manually ?
- If Oem have I to install package and pay a licence for it ?
- If brocker, have I to install a patch or package on an other server. and If "yes" what and where is the patch ?
- 2 - My database primary failed who modify the secondary database and start this database in mode primary ? OEM, Brocker or mannually ?
