3. The password of the replication user that is used for streaming connection to the primary cluster.

4. A replication test that can be done to ensure the correct username and password with necessary privileges and the whether the pg_hba.conf updates are correct.

5. The result of the replication test.

6. By, default the observer is enabled that will start monitoring the configuration as soon the DR cluster is created.

7. Click start to start creating the DR cluster using WAL streaming method.

...

Below is a detailed explanation of how the DR cluster is created in the background.

...

This method of creating the standby is specific to Dbvisit. The wal files from the primary are copied to standby at regular intervals and applied on the standby.

...

-bash-4.2$ ls -lrt /u01
drwx------ (or drwxr-x---).  5 postgres postgres  4096 Aug 16 16:41 tablespace
drwx------ (or drwxr-x---). 20 postgres postgres  4096 Aug 26 12:06 PG5433-12

5. The location of the configuration files (postgresql.conf, pg_hba.conf, and pg_indent.conf). This location can be different from the primary data directory, but the example below has these two in the same directory. Keeping the same as the primary is recommended, but this can also be different in the standby. postgresql.conf, pg_hba.conf, and pg_indent.conf need to be placed in the same folder.

6. For this example, a Hot standby is created that can be accessible for reporting purposes as the databases in the cluster are in read only mode.
