Backing up an Oracle Data Guard environment

Figure 4 below lists the configuration files on the used setup as an example.

Figure 4 Primary instance - Configuration Files

Now copy both files into the same directory and replace the primary system name (oracle2 in our

example) by the standby system name (oracle1), so you should have now 4 files listed as seen in

Figure 5. There is no need to modify the contents of the files.

Figure 5 Primary and Standby Configuration Files

CAUTION

It is required to have the same Oracle Configuration settings for Primary

and Standby instance. ORACLE_HOME, ORACLE_SID, DBID might be the

same (Oracle Data Guard requirements), but database connection string is

not identically as a default – see details below how to configure tnsnames

resolution.

Data Protector stores the connection strings in encrypted way. In case primary and standby instance

are using different connection strings the described setup will fail.
